Base Ten Block Facts

 FACTS ABOUT THE BASE TEN BLOCKS.

1) Dimensions of 1 ones block = 1 cm by 1 cm by 1 cm. So, volume = 1 cm cube. 

Total surface area = 6 x 1 cm sq = 6 cm sq. 

2) Dimensions of 1 tens block = 10 cm by 1 cm by 1 cm. So, volume = 10 cm cube. Total surface area = 4 x 10 cm sq + 2 x 1 cm sq = 42 cm sq. 

3) Dimensions of 1 hundreds block = 10 cm by 10 cm by 1 cm. So, volume = 100 cm cube. Total surface area = 4 x 10 cm sq + 2 x 100 cm sq = 240 cm sq. 

4) Dimensions of 1 thousands block is 10 cm by 10 cm by 10 cm. So, volume = 1000 cm cube. Total surface area = 6 x 100 cm sq = 600 cm sq. 

Because of the above facts, we can even use base ten blocks to teach other topics like measurements in mathematics and volume calculations in science.

Pedagogy of Mathematics

 Mathematics...

“Teaching of Mathematics is a challenging adventure. It has its own discouragements, its danger and its rewards. 

Mathematics is a creation of human mind concerned chiefly with ideas, process and reasoning and hence it requires much careful attention, efforts, concentration and clear thinking on the part of the teacher as well as the students. So the teachers and curriculum framers should select and grade the materials in the order of difficulty. The important educational maxims such as easy to difficult, near to remote, simple to complex, known to unknown, concrete to abstract, particular to general, empirical to rational are the techniques or guiding principles of grading the content and methodology of Mathematics.” 

An excerpt from the book ‘Pedagogy of Mathematics’ authored by Dr. P.M Jaleel and Dr. Sajna Jaleel

Math Myths

 Twelve Math Myths

1. MEN ARE BETTER IN MATH THAN WOMEN.

Research has failed to show any difference between men and women in mathematical ability. Men are reluctant to admit they have problems so they express difficulty with math by saying, "I could do it if I tried." Women are often too ready to admit inadequacy and say, "I just can't do math."


2. MATH REQUIRES LOGIC, NOT INTUITION. 

Few people are aware that intuition is the cornerstone of doing math and solving problems. Mathematicians always think intuitively first. Everyone has mathematical intuition; they just have not learned to use or trust it. It is amazing how often the first idea you come up with turns out to be correct.


3. MATH IS NOT CREATIVE. 

Creativity is as central to mathematics as it is to art, literature, and music. The act of creation involves diametrical opposites--working intensely and relaxing, the frustration of failure and elation of discovery, satisfaction of seeing all the pieces fit together. It requires imagination, intellect, intuition, and aesthetic about the rightness of things.


4. YOU MUST ALWAYS KNOW HOW YOU GOT THE ANSWER.

Getting the answer to a problem and knowing how the answer was derived are independent processes. If you are consistently right, then you know how to do the problem. There is no need to explain it.


5. THERE IS A BEST WAY TO DO MATH PROBLEMS. 

A math problem may be solved by a variety of methods which express individuality and originality-but there is no best way. New and interesting techniques for doing all levels of mathematics, from arithmetic to calculus, have been discovered by students. The way math is done is very individual and personal and the best method is the one which you feel most comfortable.


6. IT'S ALWAYS IMPORTANT TO GET THE ANSWER EXACTLY RIGHT.

The ability to obtain approximate answer is often more important than getting exact answers. Feeling about the importance of the answer often are a reversion to early school years when arithmetic was taught as a feeling that you were "good" when you got the right answer and "bad" when you did not.


7. IT'S BAD TO COUNT ON YOUR FINGERS.

There is nothing wrong with counting on fingers as an aid to doing arithmetic. Counting on fingers actually indicates an understanding of arithmetic-more understanding than if everything were memorized.


8. MATHEMATICIANS DO PROBLEMS QUICKLY, IN THEIR HEADS.

Solving new problems or learning new material is always difficult and time consuming. The only problems mathematicians do quickly are those they have solved before. Speed is not a measure of ability. It is the result of experience and practice.


9. MATH REQUIRES A GOOD MEMORY.

Knowing math means that concepts make sense to you and rules and formulas seem natural. This kind of knowledge cannot be gained through rote memorization.


10. MATH IS DONE BY WORKING INTENSELY UNTIL THE PROBLEM IS SOLVED.Solving problems requires both resting and working intensely. Going away from a problem and later returning to it allows your mind time to assimilate ideas and develop new ones. Often, upon coming back to a problem a new insight is experienced which unlocks the solution.


11. SOME PEOPLE HAVE A "MATH MIND" AND SOME DON'T.

Belief in myths about how math is done leads to a complete lack of self-confidence. But it is self-confidence that is one of the most important determining factors in mathematical performance. We have yet to encounter anyone who could not attain his or her goals once the emotional blocks were removed.


12. THERE IS A MAGIC KEY TO DOING MATH.

There is no formula, rule, or general guideline which will suddenly unlock the mysteries of math. If there is a key to doing math, it is in overcoming anxiety about the subject and in using the same skills you use to do everything else.

Methodology and Pedagogical Analysis of Primary Mathematics


Introduction
Education is not only considered essential for the pleasant development of one’s personality but also for the growth and progression of the country as a whole. Elementary education is regarded as the foundation for the growth of not only the individuals but for the welfare of the entire nation. Elementary education in India is regarded as the foundation of compulsory schooling that is considered essential for the individuals. It is preceded by pre-school or nursery education and is followed by secondary education.
The central government and the state government and other organizations have been involved in the progression of elementary education. The 86th constitutional amendment act, 2002 made education the fundamental right of the children within the age group of six to fourteen years. Right of Children to Free and Compulsory Education Act, 2009 was recognized. It stated all children should be made provision of free education up to the age of fourteen years. The role of education within the framework of social and economic progress is well recognized. Universalisation of Elementary Education (UEE) has opened up opportunities for the individuals leading to their social and economic development. Education is not only meant to improve the knowledge of the individuals but also in enhancing the overall quality of life.
Purpose (Aims) of Elementary Mathematics Education
The primary grades are often considered the most important years of a child’s school career. In grades K–5, students acquire content knowledge that they will use as the foundation for the rest of their education. As with all of the core subjects, there are certain objectives for mathematics that should be addressed in the primary grades.
The primary grades are often considered the most important years of a child’s school career. In grades K–5, students acquire content knowledge that they will use as the foundation for the rest of their education. As with all of the core subjects, there are certain objectives for mathematics that should be addressed in the primary grades.
Mathematics introduces children to concepts, skills and thinking strategies that are essential in everyday life and support learning across the curriculum. It helps children make sense of the numbers, patterns and shapes they see in the world around them, offers ways of handling data in an increasingly digital world and makes a crucial contribution to their development as successful learners. Children delight in using mathematics to solve a problem, especially when it leads them to an unexpected discovery or new connections. As their confidence grows, they look for patterns, use logical reasoning, suggest solutions and try out different approaches to problems. Mathematics offers children a powerful way of communicating. They learn to explore and explain their ideas using symbols, diagrams and spoken and written language. They start to discover how mathematics has developed over time and contributes to our economy, society and culture. Studying mathematics stimulates curiosity, fosters creativity and equips children with the skills they need in life beyond school.
One of the skills needed to be successful in the 21st century, elementary math is becoming an increasingly important part of early childhood education.
According to the National Association for the Education of Young Children, the math skills that students learn at a young age build a foundation for future learning endeavors and can be a good indicator of whether or not young people will be able to meet and overcome new challenges as they mature.
"Mastery of early math skills predicts not only future math achievement, it also predicts future reading achievement," Greg Duncan, a researcher at Northwestern University, said in a statement.
The following are some of the important aims of Mathematics education at elementary level.
·       Acquire understanding of numbers and numeration

Curriculum of Elementary Mathematics Education
The word curriculum is derived from the Latin word ‘currere’ which means ‘run’. Thus curriculum means a course to be run for reaching a certain goal or destination. Thus the traditional definition of curriculum is a course of study or training leading to a product or education. Teaching learning process does not operate in a vacuum. Certain planned experiences have to be provided in a school so that optimum human development according to the needs of a particular country is possible. Thus the term curriculum in recent years has come to mean all the planned activities and experiences available to the students under the direction of the school.
The primary grades are often considered the most important years of a child’s school career. In grades K–5, students acquire content knowledge that they will use as the foundation for the rest of their education. As with all of the core subjects, there are certain objectives for mathematics that should be addressed in the primary grades.
Numbers and Basic Functions
At the most basic level, mathematics involves counting, recognizing numbers and performing simple operations like addition and subtraction. In the primary grades, students should be provided with numerous opportunities to master these skills. Upon exiting primary school, children should be comfortable with writing and identifying numbers, rote counting forward and backward and comparing numbers and quantities. Primary students should have knowledge of number facts and families. They should also be able to add, subtract, multiply and divide numbers.
Measurement and Estimation
In the primary grades, students should be taught about the measurement of length, weight and capacity. Children should be introduced to the comparative language, such as "shorter," "heavier" and "longer," and should be able to apply these concepts when considering different objects and units of measurement. Primary students should also learn about money and time and be able to measure time in terms of hours, days, months and years. In addition to measurement, children should be taught about the estimation of quantities and capacities.
Geometry
Learning about shapes, symmetry, position and direction is a key objective for primary school mathematics. Students should be exposed to two- and three-dimensional shapes and be able to identify, name and draw them. Children in the primary grades should also have an understanding of line and rotational symmetry, as well as the manipulation of objects in space. Additional spatial concepts of position, like "above," "under," "next to" and "beyond," should be addressed in primary mathematics education as well.
Data Collection and Interpretation
Being able to collect, organize and interpret data is an important skill that is taught in the primary grades. Students should be given opportunities to answer questions through sorting and organizing data by using graphs, charts, tables and Venn diagrams. They should also learn to compare objects and data based on given criteria.
Critical Thinking and Problem Solving
Mathematics should be used to develop critical thinking and problem solving. Presented with a problem or situation, primary students should be able to identify the proper strategies needed to come to conclusions and carry out calculations. Throughout primary school, students should progress from using concrete objects and written calculations to carrying out operations mentally. Children in primary school should also have the ability to identify and continue patterns, provide examples and non-examples of mathematical statements, and form and test hypotheses.
Appreciation and Uses
One of the most important aims of students at this level is to develop a positive attitude toward mathematics. Students should understand and appreciate the functionality of mathematics. In addition to valuing math, primary school students need to be taught how to use mathematics in their everyday lives. They should be exposed to all the uses of mathematics, from counting out change or telling time to use angles in architecture or art.
Methodology

In the changing scenario, students’ involvement in classroom, teaching method and teachers’ commitment are the factors that affect the teaching learning process. The traditional aspects of educational outcomes are based on pure (factual) subject knowledge and its memorization. On the other hand, modern aspects of educational outcomes concentrate on the progressive side of knowledge and its applications with individual involvement (Dogan, 2011)
According to the National Council of Teachers of Mathematics (NCTM) there are five process strands in teaching mathematics at any level.

   iv.         Connections

ü  Recognize and use connections among mathematical ideas
ü  Understand how mathematical ideas interconnect and build on one another to produce a coherent whole
ü  Recognize and apply mathematics in contexts outside of mathematics

     v.         Representation

ü  Create and use representations to organize, record, and communicate mathematical ideas
ü  Select, apply, and translate among mathematical representations to solve problems
ü  Use representations to model and interpret physical, social, and mathematical phenomena
The elementary mathematics teachers must handle the mathematics teaching in the following ways.

ü Reason abstractly, reflectively, and quantitatively with attention to units, constructing viable arguments and proofs, and critiquing the reasoning of others; represent and model generalizations using mathematics; recognize structure and express regularity in patterns of mathematical reasoning; use multiple representations to model and describe mathematics; and utilize appropriate mathematical vocabulary and symbols to communicate mathematical ideas to others.
ü Formulate, represent, analyse, and interpret mathematical models derived from real-world contexts or mathematical problems.
ü Organize mathematical thinking and use the language of mathematics to express ideas precisely, both orally and in writing to multiple audiences.
ü Demonstrate the interconnectedness of mathematical ideas and how they build on one another and recognize and apply mathematical connections among mathematical ideas and across various content areas and real-world contexts.
ü Model how the development of mathematical understanding within and among mathematical domains intersects with the mathematical practices of problem solving, reasoning, communicating, connecting, and representing.

   iii.         Content Pedagogy

relationship to student learning within and across mathematical domains in teaching elementary students and coaching/mentoring elementary classroom teachers.
ü Analyze and consider research in planning for and leading students and the teachers they coach/mentor in rich mathematical learning experiences.
ü Plan and assist others in planning lessons and units that incorporate a variety of strategies, differentiated instruction for diverse populations, and mathematics-specific and instructional technologies in building all students’ conceptual understanding and procedural proficiency.
ü Provide students and teachers with opportunities to communicate about mathematics and make connections among mathematics, other content areas, everyday life, and the workplace.
ü Implement and promote techniques related to student engagement and communication including selecting high quality tasks, guiding mathematical discussions, identifying key mathematical ideas, identifying and addressing student misconceptions, and employing a range of questioning strategies.
ü 3f) Plan, select, implement, interpret, and assist teachers in using formative and summative assessments to inform instruction by reflecting on mathematical proficiencies essential for all students.
ü Monitor students’ progress and assist others, including family members, administrators and other stakeholders, in making instructional decisions and in measuring and interpreting students’ mathematical understanding and ability using formative and summative assessments.

ü Engage students and coach/mentor teachers in using developmentally appropriate mathematical activities and investigations that require active engagement and include mathematics-specific technology in building new knowledge.
ü Collect, organize, analyse, and reflect on diagnostic, formative, and summative assessment evidence and determine the extent to which students’ mathematical proficiencies have increased as a result of their instruction or their efforts in coaching/mentoring teachers.
Approaches in Teaching Elementary Mathematics
Use Everyday Objects
we already have everything we need to begin teaching math to our child. Buttons, pennies, money, books, fruit, soup cans, trees, cars — we can count the objects you have available. Math is easy to teach when we look at all of the physical objects we can count, add, subtract, and multiply.
Everyday objects also help us teach our child that objects don't have to be identical to be important in math. Counting apples is a great math lesson, but counting apples, oranges, and watermelons together expand the thought process. The child is connecting counting with various objects, instead of running through a routine numbers game of 1, 2, 3.
Use Dramatizations
 Invite children to pretend to be in a ball (sphere) or box (rectangular prism), feeling the faces, edges, and corners and to dramatize simple arithmetic problems such as: Three frogs jumped in the pond, then one more, how many are there in all?
Use Children's Bodies
Suggest that children show how many feet, mouths, and so on they have. When asked to show their "three arms," they respond loudly in protest, and then tell the adult how many they do have and show ("prove") it. Then invite children to show numbers with fingers, starting with the familiar, "How old are you?" to showing numbers you say, to showing numbers in different ways (for example, five as three on one hand and two on the other).
Use Children's Play
Engage children in block play that allows them to do mathematics in numerous ways, including sorting, seriating, creating symmetric designs and buildings, making patterns, and so forth. Then introduce a game of Dinosaur Shop. Suggest that children pretend to buy and sell toy dinosaurs or other small objects, learning counting, arithmetic, and money concepts.
Use Children's Toys
Encourage children to use "scenes" and toys to act out situations such as three cars on the road, or, later in the year, two monkeys in the trees and two on the ground.
Use Children's Stories
Share books with children that address mathematics but are also good stories. Later, help children see mathematics in any book. In Blueberries for Sal, by Robert McCloskey (Penguin, 1993), children can copy "kuplink, kuplank, kuplunk!" and later tell you the number as you slowly drop up to four counters into a coffee can.
Use Children's Natural Creativity
 Children's ideas about mathematics should be discussed with all children. Here's a "mathematical conversation" between two boys, each 6 years of age: "Think of the biggest number you can. Now add five. Then, imagine if you had that many cupcakes." " Wow, that's five more than the biggest number you could come up with!"
Use Children's Problem-solving Abilities
 Ask children to describe how they would figure out problems such as getting just enough scissors for their table or how many snacks they would need if a guest were joining the group. Encourage them to use their own fingers or manipulatives or whatever else might be handy for problem solving.
Use a Variety of Strategies
Bring mathematics everywhere you go in your classroom, from counting children at morning meeting to setting the table, to asking children to clean up a given number or shape of items. Also, use a research-based curriculum to incorporate a sequenced series of learning activities into your program.

Use Technology
Try digital cameras to record children's mathematical work, in their play and in planned activities, and then use the photographs to aid discussions and reflections with children, curriculum planning, and communication with parents. Use computers wisely to mathematize situations and provide individualized instruction.
Use Assessments to Measure Children's Mathematics Learning
Use observations, discussions with children, and small-group activities to learn about children's mathematical thinking and to make informed decisions about what each child might be able to learn from future experiences. Also try computer assessments. Use programs that assess children automatically.
Assessment
Assessment is the means by which we determine what students know and can do. It tells teachers, students, parents, and policymakers something about what students have learned: the mathematical terms they recognize and can use, the procedures they can carry out, the kind of mathematical thinking they do, the concepts they understand, and the problems they can formulate and solve. It provides information that can be used to award grades, to evaluate a curriculum, or to decide whether to review fractions. Assessment can help convince the public and educators that change is needed in the short run and that the efforts to change mathematics education is worthwhile in the long run.
Assessment basically consists of two types, formative and summative. The formative is ongoing process and the later is pencil-paper test. Whatever the type of assessment we take, there are certain principles to follow.
Principles for Assessing Mathematics Learning
      i.         The Content Principle
Assessment should reflect the mathematics that is most important for students to learn. Any assessment of mathematics learning should first and foremost be anchored in important mathematical content. It should reflect topics and applications that are critical to a full understanding of mathematics as it is used in today's world and in students' later lives, whether in the workplace or in later studies. Assessments should reflect processes that are required for doing mathematics: reasoning, problem solving, communication, and connecting ideas. Consensus has been achieved within the discipline of mathematics and among organizations representing mathematics educators and teachers on what constitutes important mathematics. Although such consensus is a necessary starting point, it is important to obtain public acceptance of these ideas and to preserve local flexibility to determine how agreed-upon standards are reflected in assessments as well as in curricula.
Assessment makes sense only if it is in harmony with the broad goals of mathematics education reform.
     ii.         The Learning Principle

Assessment should enhance mathematics learning and support good instructional practice. Although assessments can be undertaken for various purposes and used in many ways, proponents of standards-based assessment reform have argued for the use of assessments that contribute very directly to student learning. The rationale is that challenging students to be creative and to formulate and solve problems will not ring true if all students see are quizzes, tests, and examinations that dwell on routine knowledge and skill. Consciously or unconsciously, students use assessments they are given to determine what others consider to be significant.

   iii.         The Equity Principle

Assessment should support every student's opportunity to learn important mathematics. The equity principle aims to ensure that assessments are designed to give every student a fair chance to demonstrate his or her best work and are used to provide every student with access to challenging mathematics. Equity requires careful attention to the many ways in which understanding of mathematics can be demonstrated and the many factors that may colour judgments of mathematical competence from a particular collection of assessment tasks.
Equity also requires attention to how assessment results are used. Often assessments have been used inappropriately to filter students out of the educational opportunity. They might be used instead to empower students: to provide students the flexibility needed to do their best work, to provide concrete examples of good work so that students will know what to aim for in learning, and to elevate the students' and others' expectations of what can be achieved.
Equity also requires that policies regarding use of assessment results make clear the schools' obligations to educate students to the level of new content and performance standards.
Purpose of Classroom Assessment
One of the first things to consider when planning for assessment is its purpose. Who will use the results? For what will they use them?
Assessment is used to:
ü  inform and guide teaching and learning

A good classroom assessment plan gathers evidence of student learning that informs teachers' instructional decisions. It provides teachers with information about what students know and can do. To plan effective instruction, teachers also need to know what the student misunderstands and where the misconceptions lie. In addition to helping teachers formulate the next teaching steps, a good classroom assessment plan provides a road map for students. Students should, at all times, have access to the assessment so they can use it to inform and guide their learning.

ü  help students set learning goals
Students need frequent opportunities to reflect on where their learning is at and what needs to be done to achieve their learning goals. When students are actively involved in assessing their own next learning steps and creating goals to accomplish them, they make major advances in directing their learning and what they understand about themselves as learners.
ü  assign report card grades
Grades provide parents, employers, other schools, governments, post-secondary institutions and others with summary information about student learning.
ü  motivate students
Research (Davies 2004; Stiggins et al. 2004) has shown that students will be motivated and confident learners when they experience progress and achievement, rather than the failure and defeat associated with being compared to more successful peers.
The Assessment Process
ü  Effective classroom assessment in mathematics:
ü  addresses specific outcomes in the program of studies
ü  shares intended outcomes and assessment criteria with students prior to the assessment activity
ü  assesses before, during and after instruction
ü  employs a variety of assessment strategies to provide evidence of student learning
ü  provides frequent and descriptive feedback to students
ü  ensures students can describe their progress and achievement and articulate what comes next in their learning
ü  informs teachers and provides insight that can be used to modify instruction.
The assessment process starts with planning based on the program of studies learning outcomes and involves assessing, evaluating and communicating student learning, as shown in the following diagram.
What to Assess
The process of assessment in mathematics includes the following dimensions of
mathematical learning:
ü  concepts and procedures
ü  mathematical reasoning
ü  dispositions towards mathematics
ü  using mathematical knowledge and techniques to solve problems
ü  communication
Types of Assessment
Pre-assessment or diagnostic assessment
Before creating the instruction, it’s necessary to know for what kind of students you’re creating the instruction. Your goal is to get to know your student’s strengths, weaknesses and the skills and knowledge they possess before taking the instruction. Based on the data you’ve collected, you can create your instruction.
Formative assessment – Assessment for Learning
Formative assessment is used in the first attempt of developing instruction. The goal is to monitor student learning to provide feedback. It helps to identify the first gaps in your instruction. Based on this feedback you’ll know what to focus on for further expansion for your instruction.
Assessment for learning is ongoing assessment that allows teachers to monitor students on a day-to-day basis and modify their teaching based on what the students need to be successful. This assessment provides students with the timely, specific feedback that they need to make adjustments to their learning.
After teaching a lesson, we need to determine whether the lesson was accessible to all students while still challenging to the more capable; what the students learned and still need to know; how we can improve the lesson to make it more effective; and, if necessary, what other lesson we might offer as a better alternative. This continual evaluation of instructional choices is at the heart of improving our teaching practice.
Summative assessment – Assessment of Learning
Summative assessment is aimed at assessing the extent to which the most important outcomes at the end of the instruction have been reached. But it measures more: the effectiveness of learning, reactions on the instruction and the benefits on a long-term base. The long-term benefits can be determined by following students who attend your course, or test. You are able to see whether and how they use the learned knowledge, skills and attitudes.
Assessment as Learning
Assessment as learning develops and supports students' metacognitive skills. This form of assessment is crucial in helping students become lifelong learners. As students engage in peer and self-assessment, they learn to make sense of information, relate it to prior knowledge and use it for new learning. Students develop a sense of ownership and efficacy when they use teacher, peer and self-assessment feedback to make adjustments, improvements and changes to what they understand.
Confirmative assessment
When your instruction has been implemented in your classroom, it’s still necessary to take assessment. Your goal with confirmative assessments is to find out if the instruction is still a success after a year, for example, and if the way you're teaching is still on point. You could say that a confirmative assessment is the extensive form of a summative assessment.
Norm-referenced assessment
This compares a student’s performance against an average norm. This could be the average national norm for the subject History, for example. Another example is when the teacher compares the average grade of his or her students against the average grade of the entire school.
Criterion-referenced assessment
It measures student’s performances against a fixed set of predetermined criteria or learning standards. It checks what students are expected to know and be able to do at a specific stage of their education. Criterion-referenced tests are used to evaluate a specific body of knowledge or skill set, it’s a test to evaluate the curriculum taught in a course.
Ipsative assessment
It measures the performance of a student against previous performances from that student. With this method you’re trying to improve yourself by comparing previous results. You’re not comparing yourself against other students, which may be not so good for your self-confidence.
Tools and Techniques for Assessment
As students work with mathematical tasks, they should be able to:
ü  explain, interpret and justify what they know in their own ways, not just present what others have said about the topic
ü  make and explore connections that are not immediately obvious
ü  speak to their peers about the personal strategies they have used to arrive at their solutions
ü  provide evidence of their learning based on explicit criteria
ü  create new ways to express ideas, insights and feelings; e.g., making models or representations as they devise various ways to solve a problem, justifying their solutions, creating simulations, working with what they understand in new situations or contexts
ü  take action when they recognize that their understanding of issues, problems and ideas could be improved.
Teachers can use a variety of assessment tools and strategies to assess student performance. Some of these strategies and tools include:
Anecdotal Notes
Anecdotal notes are used to record specific observations of individual student behaviours, skills and attitudes as they relate to the outcomes in the program of studies. Such notes provide cumulative information on student learning and direction for further instruction. Anecdotal notes are often written as the result of ongoing observations during the lessons but may also be written in response to a product or performance the student has completed. They are brief, objective and focused on specific outcomes. Notes taken during or immediately following an activity are generally the most accurate. Anecdotal notes for a particular student can be periodically shared with that student or be shared at the student’s request. They can also be shared with students and parents at parent–teacher–student conferences.
The purpose of anecdotal notes is to:
ü  provide information regarding a student's development over a period of time
ü  provide ongoing records about individual instructional needs
ü  capture observations of significant behaviours that might otherwise be lost
ü  provide ongoing documentation of learning that may be shared with students, parents and teachers.
Tips for Establishing and Maintaining Anecdotal Notes
ü  Keep a binder with a separate page for each student. Record observations using a clipboard and sticky notes. Write the date and the student’s name on each sticky note. Following the note taking, place individual sticky notes on the page reserved for that student in the binder.
ü  Keep a binder with dividers for each student and blank pages to jot down notes. The pages may be divided into three columns: Date, Observation and Action Plan.
ü  Keep a class list in the front of the binder and check off each student's name as anecdotal notes are added to their section of the binder. This provides a quick reference of the students you have observed and how frequently you have observed them.
ü  Keep notes brief and focused (usually no more than a few sentences or phrases).
ü  Note the context and any comments or questions for follow-up.
ü  Keep comments objective. Make specific comments about student strengths, especially after several observations have been recorded and a pattern has been observed.
ü  Record as the observations are being made, or as soon after as possible, so recollections will be accurate.
ü  Record comments regularly, if possible.
ü  Record at different times and during different activities to develop a balanced profile of student mathematics learning.
ü  Review records frequently to ensure that notes are being made on each student regularly and summarize information related to trends in students' learning.
ü  Share anecdotal notes with students and parents at conferences.
Observation Checklists
Observing students as they solve problems, model skills to others, think aloud during a sequence of activities or interact with peers in different learning situations provides insight into student learning and growth. The teacher finds out under what conditions success is most likely, what individual students do when they encounter difficulty, how interaction with others affects their learning and concentration, and what students need to learn next. Observations maybe informal or highly structured, and incidental or scheduled over different periods of time in different learning contexts.
Observation checklists allow teachers to record information quickly about how students perform in relation to specific outcomes from the program of studies. Observation checklists, written in a yes/no format can be used to assist in observing student performance relative to specific criteria. They may be directed toward observations of an individual or group. These tools can also include spaces for brief comments, which provide additional information not captured in the checklist.
Before you use an observation checklist, ensure students understand what information will be gathered and how it will be used. Ensure checklists are dated to provide a record of observations over a period of time.
Tips for Using Observation Checklists
ü  Determine specific outcomes to observe and assess.
ü  Decide what to look for. Write down criteria or evidence that indicates the student is demonstrating the outcome.
ü  Ensure students know and understand what the criteria are.
ü  Target your observation by selecting four to five students per class and one or two specific outcomes to observe.
ü  Develop a data gathering system, such as a clipboard for anecdotal notes, a checklist or rubric, or a video or audio recorder.
ü  Collect observations over a number of classes during a reporting period and look for patterns of performance.
ü  Date all observations.
ü  Share observations with students, both individually and in a group. Make the observations specific and describe how this demonstrates or promotes thinking and learning. For example; "Eric, you contributed several ideas to your group's Top Ten list. You really helped your group finish their task within the time limit."
ü  Use the information gathered from observation to enhance or modify future instruction.
Conversations
Learning conversations are particularly effective in helping students make connections. There are a number of ways to keep track of learning conversations. For example:
ü  Record the learning conversations by using a digital recording device. Either the teacher or students can download the recording and use audio editing software to identify the most salient parts of the conversation and add them to their portfolios.
ü  Record the learning conversations by video. Either the teacher or students can create video recording and use video editing software to identify the most salient parts of the conversation and add them to their portfolios.
ü  Record their emerging understandings, working theories, solutions and reflections through a classroom Web site; e.g., chatroom, blogs, wiki. Students can then continue their conversations outside of school, build on each other's ideas, and have a rich record of how their knowledge was built and how deep understanding emerged through open conversation.
Portfolios
A portfolio is a purposeful collection of student work samples, student self-assessments and goal statements that reflect student progress. Students generally choose the work samples to place in the portfolio, but the teacher may also recommend that specific work samples be included. Portfolios are powerful tools that allow students to see their academic progress from grade to grade.
The physical structure of a portfolio refers to the actual arrangement of the work samples, which can be organized according to chronology, subject area, style or goal area. The conceptual structure refers to the teacher's goals for student learning. For example, the teacher may have students complete a self-assessment on a work sample and then set a goal for future learning. The work sample self‑assessment and the goal sheet may be added to the portfolio
Work samples from all curricular areas can be selected and placed in a portfolio. These can include stories, tests and reflections about work samples.
Effective portfolios:
ü  are updated regularly to keep them as current and complete as possible
ü  help students examine their progress
ü  help students develop a positive self-concept as learners
ü  are shared with parents or guardians
ü  are a planned, organized collection of student-selected work
ü  tell detailed stories about a variety of student outcomes that would otherwise be difficult to document
ü  include self-assessments that describe the student as both a learner and an individual
ü  serve as a guide for future learning by illustrating a student's present level of achievement
ü  include a selection of items that are the representative of curriculum outcomes, and what the student knows and can do
ü  include the criteria against which the student work was evaluated
ü  support the assessment, evaluation and communication of student learning
ü  document learning in a variety of ways—process, product, growth and achievement
ü  include a variety of works—audio recordings, video recordings, photographs, graphic organizers, first drafts, journals and assignments that feature work from all of the multiple intelligences.
An essential requirement of portfolios is that students include written reflections that explain why each sample was selected. The power of the portfolio is derived from the descriptions, reactions and metacognitive reflections that help students achieve their goals. Conferencing with parents, peers and/or teachers helps synthesize learning and celebrate successes. Some students become adept at writing descriptions and personal reflections of their work without any prompts. For students who have difficulty deciding what to write, sentence starters might be useful.
Question and Answer
Questioning serves as assessment when it is related to outcomes. Teachers use questioning (usually oral) to discover what students know and can do. Strategies for effective question and answer assessment include:
ü  Apply a wait time or 'no hands-up rule' to provide students with time to think after a question before they are called upon randomly to respond.
ü  Ask a variety of questions, including open-ended questions and those that require more than a right or wrong answer.
ü  Use Bloom's Taxonomy when developing questions to promote higher-order thinking.
ü  Teachers can record the results of question and answers in anecdotal notes or include them as part of their planning to improve student learning.
Checklists, Rating Scales and Rubrics
Checklists, rating scales and rubrics are tools that state specific criteria and allow teachers and students to gather information and to make judgments about what students know and can do in relation to the outcomes. They offer systematic ways of collecting data about specific behaviours, knowledge and skills.
The quality of information acquired through the use of checklists, rating scales and rubrics is highly dependent on the quality of the descriptors chosen for assessment. Their benefit is also dependent on students’ direct involvement in the assessment and understanding of the feedback provided.
The purpose of checklists, rating scales and rubrics is to:
ü  provide tools for systematic recording of observations
ü  provide tools for self-assessment
ü  provide samples of criteria for students prior to collecting and evaluating data on their work
ü  record the development of specific skills, strategies, attitudes, and behaviours necessary for demonstrating learning
ü  clarify students' instructional needs by presenting a record of current accomplishments.
Tips for Developing Checklists, Rating Scales and Rubrics
ü  Use checklists, rating scales and rubrics in relation to outcomes and standards.
ü  Use simple formats that can be understood by students and that will communicate information about student learning to parents.
ü  Ensure that the characteristics and descriptors listed are clear, specific and observable.
ü  Encourage students to assist with constructing appropriate criteria. For example, what are the descriptors that demonstrate levels of performance in problem solving?
ü  Ensure that checklists, rating scales and rubrics are dated to track progress over time.
ü  Leave space to record anecdotal notes or comments.
ü  Use generic templates that become familiar to students and to which various descriptors can be added quickly, depending on the outcome(s) being assessed.
ü  Provide guidance to students to use and create their own checklists, rating scales, and rubrics for self-assessment purposes and as guidelines for goal setting.
Checklists usually offer a yes/no format in relation to student demonstration of specific criteria. This is similar to a light switch; the light is either on or off. They may be used to record observations of an individual, a group or a whole class.
Rating Scales allow teachers to indicate the degree or frequency of the behaviours, skills, and strategies displayed by the learner. To continue the light switch analogy, a rating scale is like a dimmer switch that provides for a range of performance levels. Rating scales state the criteria and provide three or four response selections to describe the quality or frequency of student work.
Teachers can use rating scales to record observations and students can use them as self-assessment tools. Teaching students to use descriptive words, such as always, usually, sometimes and never helps them pinpoint specific strengths and needs. Rating scales also give students information for setting goals and improving performance. On a rating scale, the descriptive word is more important than the related number. The more precise and descriptive the words for each scale point, the more reliable the tool.
Effective rating scales use descriptors with clearly understood measures, such as frequency. Scales that rely on subjective descriptors of quality, such as fair, good or excellent, are less effective because the single adjective does not contain enough information on what criteria are indicated at each of these points on the scale.
