CHAPTER FIRST
INTRODUCTION
1.0 INTRODUCTION
Human being needs minimum knowledge of Mathematics for their survival. It
is needed daily by everybody. In this complex world passing through scientific and
technological age, the practical value of Mathematics is going to be increasingly felt
and recognised. Counting notation, addition, subtraction, multiplication, division,
weighing, measuring, buying, and many more are simple and fundamental process of
Mathematics which have got an enormous practical value in life.
The knowledge and skill in these processes can be provided effectively by
adopting innovative practices in teaching Mathematics in schools. It is our common
observation that the Mathematics subject is mainly taught by lectures. The teachers
rarely use other methods of instruction. Self developed materials are also used rarely
in teaching learning of the Mathematics subject, which results in memorization for
examination purpose and it is also observed that the students forget the content and
rarely apply it in their day-to-day. Self developed materials can help to increase the
interest of students and teachers.
Mathematics Experiment Notebooks (MEN) is new Self developed material
that can be used at upper primary classes. Development of Mathematics Experiment
Notebooks (MEN) has provided new opportunities for delivering instruction in
innovative ways. The researcher is a teacher educator working in the field since last
17 years and related to teaching “Mathematics”. He felt unsatisfied about strategy of
instruction and hence decided to undergo a research on use of Mathematics
Experiment Notebooks (MEN) to teaching Mathematics for upper primary classes.
The Mathematics Experiment Notebooks (MEN) can be more effective in comparison
with the traditional.

In this chapter the researcher has discussed about the history of Mathematics
teaching, importance of Mathematics in human life, methods of teaching
Mathematics, innovative practices in Mathematics teaching, present status of
Mathematics at upper primary level, statement of the study, definitions of the terms,
significance , scope , delimitations , objectives , assumptions , hypotheses and
organisation of the study.
1.1 HISTORICAL REVIEW OF DEVELOPMENTS IN MATHEMATICS
Mathematics is a man made and progressive science. Sudhir Kumar (2000)
and Sidhu, Kulbir Singh (1985) explained the some remarkable development, ideas
and processes in Mathematics in his books. They are considered to be landmarks in
the history of Mathematics in the following way.
The Shulba Sutra‟s (800 BC–200 AD), which gave simple rules for constructing altars
of various shapes, such as squares, rectangles, parallelograms, and others. The Shulba
Sutras gave methods for constructing a circle with approximately the same area as a
given square, which imply several different approximations of the value of π. The
Shulba Sutras compute the square root of 2 and gave a statement of the Pythagorean
Theorem.
In the 5th century AD, Aryabhata wrote the Aryabhatiya, it is related to rules
of calculation used in astronomy and mathematical mensuration.
In the 7th century, Brahmagupta identified the Brahmagupta theorem,
Brahmagupta's identity and Brahmagupta's formula, and for the first time, he clearly
explained the use of zero as both a place holder and decimal digit, and explained the
Hindu-Arabic numeral system.
In the 12th century, Bhaskara II lived in southern India and wrote extensively
on all then known branches of mathematic. His work contains mathematical objects
equivalent or approximately equivalent to infinitesimals, derivatives, the mean value
theorem and the derivative of the sine function. To what extent he anticipated the
invention of calculus is a controversial subject among historians of mathematics
In the history of mathematics there have been some very remarkable
developments in the form of discovery and evolution of certain ideas and processes.
These ideas and processes claim special status and significance in the overall progress
3
of mathematical knowledge. They are considered to be landmarks in the history of the
subject. At this moment we shall discuss only few of them.
A) Notation System
Number is one of the roots of mathematics, but it has taken roots and flowered
into a full-fledged system over the period of centuries. The origin of notation system
is as old as the man himself. It is claimed that birds and insects also have some
number sense. This elementary concept took centuries to take any concrete shape.
The primitive man used various ways to count. He used fingers, cuts in the
tree, lines on the ground, pebbles etc. for the purpose. The notation system originated
and developed differently in different countries.
a) Babylonians
The Babylonians used wedge-shaped symbols. One was represented by V, ten
was represented by <, hundred by V<.
b) Hebrews and Greeks
They used letters of the alphabet to denote numbers. For example X (alpha)
stood for one, B (beta) stood for two, and i (iota) stood for ten.
c) Roman System
The roman system is based on the idea of counting by fingers or lines. Thus I,
II, III represented one, two, and three respectively. V stands for the whole hand or the
gap between the thumb and the four fingers. To avoid the clumsy IIII for four, they
wrote I before V. This symbol also gave rise to the idea of positional value. Similarly
symbols VI, VII etc., were developed. The symbol X for ten seems to be the
combination of two fives.
d) Hindu-Arabic System
Our present system in the form of numerals 1, 2, 3, etc., was originated by
Hindus. It was transmitted to the West through the Arabs and hence the name Hindu-
Arabic System.
The early Hindus had no symbol for zero and they had different symbol for
10, 20, and 30 etc. Later on the symbol 0 was evolved by the Hindu mind, meaning
„Sunya‟ i.e. nothingness. One interpretation connects the concept of zero with Hindu
4
concept of Nirvana, the ideal state of nothingness. Arabs also made certain
modifications in the Hindu numerals. During the 13th
century the Hindu Arabic
numerals became popular in the West and virtually spread all over the world.
By and by, certain modifications and improvements were effected and the
Hindu Arabic system assumed the present shape.
B) Metric System of Weights and Measurements
Before the evolution of metric system of weights and measurements, there was
a wide variety of measuring units prevalent in different parts of the world. Due to lack
of means of communication and exchange of experiences, different regions even in
the same country used different units of measurement.
For measurement of length, man used various limbs of the body e.g. foot,
span, cubit, etc. yard came from the word yard which means a stick. In England a yard
was fixed as the distance from nose to the thumb of King Henry I. Ancient people in
India also measured the yard similarly. The unit of weight „Pound‟ was used by
Romans. At some place, the pound was considered to be of 13 ounces, at another of
13 ounces.
So there was a lot of confusion in the system of weights and measures. In
1970, the king of France decided to have uniformity in the system. He appointed a
committee of scientists for the job and also invited other nations to send their
scientists.
These scientists took the distance from the North Pole to the equator on a line
running through Paris and the one ten-millionth part of this distance was named as
meter. Now the meter is defined as the length of standard bar kept in Paris. For shorter
measurements, the meter was divided by tens.
Area
Similarly unit of area were developed on the same principle, and we have
square meters, square decimeters‟ and square centimeters as the units of area.
Weight
The weight of one cubic centimeter of water at 40C was taken as a gram. The
gram was further divided into decigrams, centigrams and milligrams and multiplied
into decagrams, hectograms, and kilograms.
5
The metric system of weights and measurements is definitely superior to non-
metric system on various grounds.
C) Logarithms
The word Logarithm is the combination of Greek words „logos‟ and
„arithmos‟. Logos means to reason, and to calculate. Arithmos means a number. Thus
Logarithm stands for calculations involving numbers.
Logarithms were invented by a Scotman , John Nepier after many years of
hard labor. The problems before him were to find out some way to cut short lengthy
calculations. Napier spent about twenty years on the theory and finally Logarithms
were evolved.
Napier began to multiply, divide, square and extracts square roots of various
numbers. Finally 1614 the first table of Logarithm of numbers was prepared.
The terms Mantissa and Characteristic were introduced by Briggs in 1624.The
first table of Logarithm of trigonometric functions to the base 10 was made by Gunter
in 1620.Gauss suggested using it for the fractional parts of all decimals.
D) Computer Mathematics
This is the age of automation. Computer have their origin in mans attempts to
find ways and means to facilitate calculations.
Probably the earliest attempt was a table of dust or sand on which calculations
were carried out with the help of stick. This was known as abacus. Next attempt
probably ruled table with small stick, pebbles or counters arranged in lines. Using the
principle of position a single bead on a line would represent 1, in next line would
represent 10 and so on.
The next development was given by Napier in1617. He arranged system of
rods to represent the method of calculation. These rods were called „Napier‟s Bones.
In 1642, Pascal developed first mechanical computer. He attached cylinders with the
notched wheels of rocks. Each wheel was divided into ten small divisions. The system
was so arranged that one complete rotation of unit wheel would turn one division on
the tens wheels and so on. It was an adding machine. Leibnitz introduced in this, a
device to calculate multiplications and divisions.
6
Towards the beginning of 19th
century, Charles Baves, a professor of
Mathematics in the Oxford University invented computer consisting of 18 wheels. In
1944, world‟s first electronic computer was invented. It was called electronic brain of
the world. It consisted of 3500 parts. It would take 300,000 micro seconds in addition
of two numbers. Then came more and more sophisticated computers.

1.2 IMPORTANCE OF MATHEMATICS IN HUMAN LIFE
Right from human existence on this earth, the man wanted to answer the
questions like; How many? How much? How big? How long? etc. For answering
these questions man invented arithmetic, algebra, geometry. This knowledge was born
in the need of human.
There is need of Mathematics in anybody‟s day-to-day and lifelong planning,
evaluation, assessment, judgment, guidance and direction for future.
The prices, rates, discounts, commissions, rebates, interest, taxes, production,
distribution, profit, loss, bank, post, shares trading etc. are the issues concerned to
everybody. There is no escape from Mathematical concepts of life and livelihood.
If we shut off Mathematics from daily life and all civilization comes to a
standstill. In this world of today nobody can live without mathematics for a single
day. Human being needs minimum knowledge of Mathematics for their survival. It is
need daily by everybody consciously or unconsciously out of his /her necessity. Any
person ignorant of Mathematics will be easily cheated. Mathematics has a constant
power on our everyday lives, and contributes to the wealth of the country. Thus
knowledge of Mathematics fundamental processes in Mathematics and the skill to use
them are the preliminary requirements of a human being these days.
The main reason for studying mathematics is that it is interesting and
enjoyable. People like its challenge, its clarity, and the fact that you know when you
are right.
Sidhu, Kulbir Singh (1985) explained the importance of Mathematics and it is
helpful to create the values, which is useful to meaningful human life.
7
These are as under:-
A) Practical value
He cannot do without learning how to count and calculate. Any person
ignorant of it, he is easily cheated in counting, notation, addition, subtraction,
multiplication, division, weighing, measuring, selling. These fundamental processes
of Mathematics have many practical values.
B) Disciplinary value
It trains and disciplines the mind. Mathematics creates discipline in the mind
because it is exact time and knowledge. It develops reasoning and thinking powers.
Reasoning in Mathematics possesses certain characteristics. These are:-
1. Characteristic of Accuracy
Accurate reasoning thinking and judgment are essential for its study.
Accuracy, exactness and precision compose the beauty of mathematics
2. Characteristic of certainty of results
The answer is either right or wrong. Subjectivity or difference of
opinion between the teacher and the taught is missing. The student can verify his
result by reverse process. It is possible for the child to remove his difficulty by self-
effort and to be sure of the removal. He develops faith in self-effort which is the
secret of success in life.
3. Characteristic of originality
Most work in mathematics demands original thinking, reproduction
and cramming of ideas of others is not very much appreciated. When the child has a
new or a different mathematical problem, it is only his originality which keeps him
going. The discovery or establishment (derivation) of a formula or conversion of
formula in one form to another is also his original work. This practice in originality
enables the child to face new and challenging problems with confidence.
4. Characteristic of similarity to the reasoning of life
Clear and exact thinking is as important in daily life as in mathematics.
Before starting with the solution of the problem, the student has to grasp the whole
8
meaning. Similarly in daily life, while undertaking a task, one must have a firm grip
over the situation.
5. Characteristic of verification of results
Results can be easily verified. This gives a sense of achievement,
confidence and pleasure. It inculcates the habit of self-criticism and self evaluation.
6. Power not knowledge
In this ever advancing society the important thing is not only to learn
facts, but also to know how to learn facts. The main thing is not the acquisition of
knowledge but the acquirement of the power of acquiring knowledge.
7. Application of knowledge
Knowledge becomes real and useful only when the mind is able to
apply it to the new situations. Ability to apply knowledge to new situations is
inculcated in students. They acquire the power to think effectively. It generates the
otherwise latent powers of thinking, reasoning, discovery and judgment of the child.
In addition to these major and fundamental disciplinary values, there are few
other values, which is of equal importance. These are: -
1. Development of concentration.
2. Power of expression.
3. Self-reliance.
4. Attitude of Discovery.
5. Quality of hard work.
C) Cultural Value
It is said, “Mathematics is the mirror of civilization”. It helped man to
overcome difficulties in the way of his progress. The prosperity of man and his
cultural advancement have depended considerably upon the advancement of
mathematics. The modern civilization owes its advancements to the progress of
various occupations such as agriculture; engineering, surveying, medicine, industry,
navigation; road-rail building etc. and contribution of mathematics in their
advancement cannot be undermined.
9
Therefore mathematics shapes culture as a play back pioneer. Some of the
important aspects of cultural heritage have been preserved in the form of
mathematical knowledge only and learning of mathematics is the only medium to pass
on this heritage to the coming generations. Mathematics is also a spin for cultural arts,
such as music, sculpture, poetry and paining.
Sidhu, Kulbir Singh: (1985) pp 9 to 14
1.3 HISTORY OF TEACHING METHODS
According to the Encyclopedia of Educational Research, (Fourth Edition) , Dr. J.V.
Naralikar , C.V. Bhimasankaram and a project of the American Educational Research
Association (1969), it was possible to saw many precursors of contemporary research
issues in the history of teaching methods.
1. The Rhetoricians used the method of systemized limitation to teach young men of
ancient Athens to speak effectively.
2. Socrates used exhortation to induce the learner to become concerned about
achieving the good, true and beautiful and engages the learner in dialectical self-
examination. He also used a kind of conditioning to discipline appetites. His
method culminated in intellectual training in dialectics by means of the Socratic
dialogue, whereby deductive relations were discovered to exist in reality,
definitions were clarified, and the relations between them were tested.
3. In the 8th
century A.D. Alcuin made use not only of riddles, poems, puzzles and
witty exchanges but also emphasized drill and repetition.
4. Abelard, in the 12th
century used the lecture method, structured materials
logically, and argued theological and philosophical issues by the method of
reconciliation between affirmative and negative sides of question.
5. In the 16th
century, Ascharm, taught the classics by the tutorial method and also
used the method of double translation in teaching languages. Individual
differences were also noticed during the teaching process.
6. The Jesults, in the 16th
century, systemized materials, methods and teacher
training, in order to standardize procedures for motivation, presentation, practice,
and testing. Individual and team rivalry, corporal punishment, reviews, lectures,
written assignments, correction work, etc. were used as techniques.
10
7. Comenius, in the 17th
century, advocated the principle of proceeding from the
universal to the particular, understanding rather than memorization, learning
through teaching others, correlation etc.
8. Pestalozzi (1746-1827) advocated the principle of proceeding from concrete to
abstract, the particular to universal, etc; full freedom was given to the physical
movements of the pupils; real object were discussed in a progression from sense
impression to formal definitions i.e. inductive process of concept formation.
9. Froebel (1782-1852) invented the kindergarten method of teaching.
10. Herbart (1876-1941) formulated ideas to identify steps in teaching, preparation,
presentation, association, systemization, and application.
11. Kilpatric (1871-1965) John Dewey‟s foremost disciple advocated the project
method.
In these sketches of teaching methods advocated by historical figures,
anticipations of following contemporary ideas issues may be discerned; the learners
developmental stages, theories of cognitive development; categories of educational
objectives; types of motivation, social arrangements, ranging from independent study
through tutoring and dialogues to competitions and lectures, issues in cognitive
structuring , such as the inductive verses the deductive arrangement of learning
experiences and the use of drill and games ; the interaction of teaching methods with
learner characteristics , so that optimal outcomes are attainable only through some
individualization , the standardization of materials and the systemization of
experience.
All these concerns of the historical examples have counter parts in the research
and developmental work of the 1960‟s.
The post-war years really witnessed remarkable and breath-taking advances in
the realm of mathematical learning. A brief review of such movements, together with
a study of factors that gave rise to them, would not therefore be out of place here.

1.4 METHODS OF TEACHING MATHEMATICS
Students have different intellectual capacities and learning styles that favor to
knowledge growth. As a result, teachers are interested in ways to effectively cause
students to understand better and learn. Teachers want to bring about better
understanding of the matter. It is the responsibility of the educational institutions and
teachers to seek more effective ways of teaching in order to meet individual‟s and
society‟s expectations from education. Improving teaching methods may help an
institution meet its goal of achieving improved learning outcomes. Sudhir Kumar
(2000) explained the methods of teaching Mathematics in his book in the following
way.
Lecture Method:
In this method teacher prepared his talk at home and pours it out in the class. The
student listens silently, attentively and tries to grasp the point. The listeners remain
passive. He may not even write anything on the black board simultaneously or may
not even argue a point with the listeners by cross questioning.
Inductive Method:
It is the method of constructing formula with the help of a sufficient number of
concrete examples. The learner proceeds from particular to general, concrete to
abstract and examples to formula. The student gets generalizations after the numbers
of concrete cases have been understood.
This method proceeds in the following way.
Observation
Comparison
Findings
Generalisation
Deductive Method:
This method is the opposite of inductive method. The learner proceeds from
general to particular, abstract to concrete and formula to examples.
The teacher told and explains the pre-constructed formula to the students and
applies the formula to solve the examples.
12
Heuristic Method:
There are no typical steps for this method. The teacher told the problem, creates a
learning situation and ask the students to solve the problem with own effort. The
teacher in the role of looker and students tries to move independently. Self
confidence, self reliant and thinking power is to be developed in the individual to
make him successful pupil.
Problem Solving Method:
The student is involved in the finding the answer to a given problem. This
method proceeds in the following way.
1. Recognising the problem
2. Defining the problem
3. Collecting relevant data
4. Organising the data
5. Formulating the tentative solution
6. Find out the correct solution
7. Verifying the result
Project Method:
Students learn better through association, cooperation and activity is the principle
of project method.This method involves the following steps
1. Providing a situation
2. Choosing
3. Planning
4. Executing
5. Evaluating
6. Recording
13
Analytical Method:
Teacher split up the unknown problem into simpler parts then these can be
recombined to find the solution or to know hidden aspects. Thorndike says that all the
highest intellectual performance of the mind is analysis.
Synthetic Method:
We proceed from known to unknown. It is the opposite of analytical method. The
teacher starts with the known data and connects to the unknown part. It is the process
of putting together of known parts of information to reach the point where unknown
information becomes obvious and true. Sudhir Kumar : (2000) pp54-82
Laboratory Method or Self-Discovery Method:
It is more elaborated and practical form of the inductive method. It makes the
subject interesting as it combines play and activating.
The construction work in geometry is on the whole a laboratory work e.g., the
drawing of a line; construction of an angle; construction of a triangle, quadrilateral,
parallelogram etc. all involve the use of some equipment and so their nature is that of
laboratory work.
This method helps to improve students‟ hand skills, makes them more
productive and increases their active involvement in learning. Students can create a
relationship between theory and practice by using experimental teaching method
.They applying theory into their real life problems through experiments.
The most challenging task of a teacher is to ensure self-learning of
Mathematics among the students. This can be best realized through “self-discovery”
method of teaching of Mathematics. The experiments envisaged precisely promote
this spirit of teaching and learning.
According to the Dr.N.M.Rao (2009) the major steps to be followed in this
approach are the following
The students predict the result experimentally by repeating the experiment
several times.
1. Prove or disprove the prediction by the deductive method of Mathematics.
14
2. Try to answer the open-ended questions at the end of the experiment and
generalize wherever possible.
Broadly, the following steps are suggested for every experiment.
1. Title of the experiment
2. Objective of the experiment
3. Description/Analysis of the experiment, with figure
4. The procedure of the experiment- How the experiment is to be conducted.
5. The prediction obtained after doing the experiment several times. The prediction
may be a correct result or may not be correct.
6. Mathematical proof/disproof of the above prediction.
7. The result (Thermos/Generalisation).
8. The open-ended questions relating to this experiment for the students to pursue the
Discovery method.
Learning by Doing:
There are several ways of learning, viz., Learning by seeing and Learning by
doing. “Learning by Doing” is one of the most effective ways of learning. It is in this
context that mathematics experiments play a vital role in not only arousing the interest
of the learner but also in making the learning of mathematics more meaningful. In the
process of “Learning by Doing”, students also learn some applications of
Mathematics in real life situations, Hence the use mathematics experiments ensures
better understanding among the students.
Mathematics Laboratory:
Mathematics Laboratory is a place where students can learn and explore
mathematical concepts and verify mathematical facts and theorems through a variety
of activities using different materials. These activities may be carried out by the
teacher or the students to explore, to learn, to stimulate interest and develop favorable
attitude towards mathematics.
Laboratory method is based on the principles of “learning by doing” and
“Learning by observation” and proceeding from concrete to abstract. Students do not
15
just listen to the information given but do something practically also. Principles have
to be discovered, generalized and established by the students in this method. Students
learn through hands on experience. This method leads the student to discover
mathematical facts. After discovering something by own efforts, the student starts
taking pride in his achievement, it gives him happiness, mental satisfaction and
encourages him towards further achievement.
Need and purpose of Mathematics Laboratory:
Dr.N.M.Rao (2009) explained some of the ways in which a Mathematics
Laboratory can contribute to the learning of the subject are:
1. It provides an opportunity to students to understand and internalize the basic
mathematical concepts through concrete objects and situations.
2. It enables the students to verify or discover several geometrical properties and facts
using models or by paper cutting and folding techniques.
3. It helps the students to build interest and confidence in learning the subject.
4. The laboratory provides opportunity to exhibit the relatedness of mathematical
concepts with everyday life.
5. It provides greater scope for individual participation in the process of learning and
becoming autonomous learners.
6. The laboratory allows and encourages the students to think, discuss with each other
and the teacher and assimilate the concepts in a more effective manner.
7. It enables the teacher to demonstrate, explain and reinforce abstract mathematical
ideas by using concrete objects, models, charts, graphs, pictures, posters, etc.
Dr.N.M.Rao: (2009) p.p.11-12
1.5 AIMS OF TEACHING OF MATHEMATICS
Education is imparted for achieving certain ends and goals. Various subjects of
the school curriculum are different means to achieve these goals so with each subject
some goals are attached which are to be achieved through teaching of that subject.
According to Sidhu, K.S. (1995) the goals of teaching mathematics are as below:
1. To develop the mathematical skills like speed, accuracy, neatness, brevity, estimation,
etc.
16
2. To develop logical thinking, reasoning power, analytical thinking, and critical-
thinking.
3. To develop power of decision-making.
4. To develop the technique of problem solving.
5. To recognize the adequacy or inadequacy of given data in relation to any problem.
6. To develop scientific attitude i.e. to estimate, find and verify results.
7. To develop ability to analyze, to draw inferences and to generalize from the collected
data and evidences.
Aims of teaching Mathematics at the elementary level.
1. To provide a good start to the pupils in learning Mathematics.
2. To provide pupils to clarify about fundamental concepts and processes of
Mathematics.
3. To create in pupils an enduring interest on the subject and to develop a love for it.
4. To introduce pupil to mathematical games puzzles, recreations, hobbies and to unfold
before them the mysteries of the subject.
5. To develop in pupils a taste for and confidence in Mathematics.
6. To develop in pupils accuracy and efficiency in fundamental processes.
7. To acquaint pupils with mathematical language and symbolism.
8. To develop in them the habits such as regularity, practice, patience, self reliance and
hard work.
9. To prepare pupils for the learning those subjects, which are intimately related with
Mathematics.
10. To acquaint pupils with mathematical language and symbolism.
11. To prepare pupils for the learning of Mathematics of higher classes.
12. To intimate and develop required discipline in the learner‟s mind.
Sidhu Kulbir Singh: (1992)
1.6 INNOVATIVE PRACTICES IN MATHEMATICS TEACHING
Mathematics is a subject which has to be learnt by doing rather than by
reading. Looking to the aims of teaching mathematics it can be seen that more focus is
laid to the higher level of objectives underlying the mathematics subject, like critical
thinking, analytical thinking, logical reasoning, and decision-making, problem-
17
solving. Such objectives are difficult to be achieved only through verbal and
mechanical methods that are usually used in the class of mathematics. The verbal
methods of instruction give all importance to speech and texts, to the book and to the
teacher. From an historical point of view this method was majorly used until the end
of the nineteenth century. In one of these verbal methods teachers are simply satisfied
with giving the mathematical rules to pupils and having them memorize it. They
justify this method by saying pupils would not understand explanations. Their task is
to transmit to their pupils the knowledge which has accumulated over the centuries, to
stuff their memory while asking them to work exercises, e.g. the rule of signs and
formulas in algebra; students memorize this and remember it! Another verbal method
involves explanation. Teachers who use this method assume that the mental structure
of the child is same as the adult‟s. But a developmental stage according to Piaget is a
period of years or months during which certain developments take place. Teachers
think teaching must imply logic, and logic being linked to language, or at least to
verbal thought, verbal teaching is supposed to be sufficient to constitute this logic.
This method leads to series of explanations and students at the initial steps of logical
explanations trying to understand and grasp but slowly the gap is created between the
explanations transmitted by teacher and received by students which lead to the poor
understanding on part of students and they develop a fear of the subject: Math‟s
phobia. The Education Commission (1964-66) points out that “In the teaching of
Mathematics emphasis should be more on the understanding of basic principles than
on the mechanical teaching of mathematical computations”. Commenting on the
prevailing situation in schools, it is observed that in the average school today
instruction still confirms to a mechanical routine, continues to be dominated by the
old besetting evil of verbalism and therefore remains dull and uninspiring.
1.7 PRESENT STATUS OF MATHEMATICS AT UPPER PRIMARY LEVEL
National Curriculum Framework 2005 proposes five guiding principles for
curriculum development:
1. Connecting knowledge to life outside the school;
2. Ensuring that learning shifts away from rote methods;
3. Enriching the curriculum so that it goes beyond textbooks;
4. Making examinations more flexible and integrating them with classroom life;
18
5. Nurturing an overriding identity informed by caring concerns within the
democratic policy of the country.
The development of the upper primary syllabus has attempted to emphasis the
development of mathematical understanding and thinking in the child. It emphasises
the need to look at the upper primary stage as the stage of transition towards greater
abstraction, where the child will move from using concrete materials and experiences
to deal with abstract notions. It has been recognized as the stage wherein the child will
learn to use and understand mathematical language including symbols. The syllabus
aims to help the learner realise that mathematics as a discipline relates to our
experiences and is used in daily life, and also has an abstract basis. All concrete
devices that are used in the classroom are scaffolds and props which are an
intermediate stage of learning. There is an emphasis in taking the child through the
process of learning to generalize, and also checking the generalization. Helping the
child to develop a better understanding of logic and appreciating the notion of proof is
also stressed. The syllabus emphasises the need to go from concrete to abstract,
consolidating and expanding the experiences of the child, helping her generalise and
learn to identify patterns. It would also make an effort to give the child many
problems to solve, puzzles and small challenges that would help her engage with
underlying concepts and ideas. The emphasis in the syllabus is not on teaching how to
use known appropriate algorithms, but on helping the child develop an understanding
of mathematics and appreciate the need for and develop different strategies for
solving and posing problems. This is in addition to giving the child ample exposure to
the standard procedures which are efficient. Children would also be expected to
formulate problems and solve them with their own group and would try to make an
effort to make mathematics a part of the outside classroom activity of the children.
The effort is to take mathematics home as a hobby as well. The syllabus believes that
language is a very important part of developing mathematical understanding. It is
expected that there would be an opportunity for the child to understand the language
of mathematics and the structure of logic underlying a problem or a description. It is
not sufficient for the ideas to be explained to the child, but the effort should be to help
her evolve her own understanding through engagement with the concepts. Children
are expected to evolve their own definitions and measure them against newer data and
information. This does not mean that no definitions or clear ideas will be presented to
19
them, but it is to suggest that sufficient scope for their own thinking would be
provided. Thus, the course would de-emphasise algorithms and remembering of facts,
and would emphasis the ability to follow logical steps, develop and understand
arguments as well. Also, an overload of concepts and ideas is being avoided. We want
to emphasis at this stage fractions, negative numbers, spatial understanding, data
handling and variables as important corner stone‟s that would formulate the ability of
the child to understand abstract mathematics. There is also an emphasis on developing
an understanding of spatial concepts. This portion would include symmetry as well as
representations of 3-D in 2-D. The syllabus brings in data handling also, as an
important component of mathematical learning. It also includes representations of
data and its simple analysis along with the idea of chance and probability.
The underlying philosophy of the course is to develop the child as being
confident and competent in doing mathematics, having the foundations to learn more
and developing an interest in doing mathematics. The focus is not on giving
complicated arithmetic and numerical calculations, but to develop a sense of
estimation and an understanding of mathematical ideas.
Taking into consideration the national aspirations and expectations reflected in
the recommendations of the National Curriculum Framework developed by NCERT,
the Central Board of Secondary Education had initiated a number of steps to make
teaching and learning of mathematics at school stage activity-based and
experimentation oriented. In addition to issuing directions to its affiliated schools to
take necessary action in this regard, a document on „Mathematics Laboratory in
Schools – towards joyful learning’ was brought out by the Board and made
available to all the schools. The document primarily aimed at sensitizing the schools
and teachers to the concept of Mathematics Laboratory and creating awareness among
schools as to how the introduction of Mathematics Laboratory will help in enhancing
teaching- learning process in the subject from the very beginning of school education.
The document also included a number of suggested hands-on activities.
The researcher has been working as lecturer in Education with Mathematics
method at the different Colleges of Education since 1993. The researcher has also
worked as an assistant teacher of Mathematics at Secondary School for four years.
The general observation of the researcher is that Mathematics has been the result
making subject at the S.S.C. and H.S.C. examination. The failure percentage of
20
students in Mathematics subject remains a point to think over. To fulfill the objectives
of the course book, there should be three main principles.
i. „Learning by doing‟,
ii. „Learning by observation‟, and
iii. Proceeding from concrete to abstract.
As per the nature of the course book, wording and language of the content is
based on practical method. NCERT published New Curriculum framework in 2001
focusing on Mathematics laboratory. This framework indicates that Mathematics
laboratory should have a place in the science laboratory.
Keeping in mind all such things, the researcher has been encouraged to
develop such a Mathematics Experiment Notebook that would enhance the pupils to
learn Mathematics in a better way which ultimately affect their achievement in
Mathematics positively.
