PIAGET'S THEORY OF COGNITIVE DEVELOPMENT

STAGES OF COGNITIVE DEVELOPMENT

Piaget identified four stages of cognitive development

1. Sensori-motor stage - Children  learn through their five senses, goal-directed actions and object-permanence. They experience ego-centricism and fail to understand others' point of view.


2. Pre-operational stage - This stage covers 2-7 years of age. Children are able to do one step logical problems, develop language but still continues to be ego-centric


3. Concrete stage - This stage occurs during 7-11 years of age and develops logical thinking and concrete ideas in the children but they still struggle with abstract ideas.



4. Formal operational stage - This stage spans from age 12 to adulthood. Children think about abstract concepts. Thinking, reasoning, planning, problem solving abilities are developed.    



Educational Implications of Piaget's Cognitive Development Theory
1. Teacher must consider maturation level of the students in order to know what and how to teach.
2. Adequate amount of concrete material is required for good understanding
3. Securing attention of the students towards material presented
4. Creating environment which is both assimilating (using pre-existing cognitive structures) and accomodating (changing the cognitive structures).

CORRELATION OF MATHEMATICS WITH OTHER SUBJECTS

Image
        Mathematics correlates with almost all school subject. Sciences uses mathematics the most. Even the Fine Arts use mathematics to some extent. Mathematics has characteristics like symmetry, similarity, originality, generalization and verification. All these characteristics make mathematics very usable, practical and versatile. Relation of mathematics with science, economics and fine arts is covered in this text Relation of Mathematics with Sciences       1. Physics  -           (i) The numerical derivations of many Laws of science are provided by mathematics.      (ii) Newton Laws of Motion, Gravitational Laws, Boyle's Law, Charles Law etc. require mathematics for practical understanding.          (iii)  All measurements, units and measuring devices depend upon mathematics.            2.  Chemistry -        (i) Chemical equations, balancing of equations       (ii) Atomic number, atomic and molecular mass, atomic mass units, radii of atoms and molecules.        (iii) Chemica

MATH PROBLEM SOLVING

Image
SOLVING A PROBLEM OR PROBLEM SOLVING IN MATHEMATICS             I have a problem, I want to solve it. Say the problem is - Who Shaves the Barber?  To solve this, do I need mathematics? The answer is No. I just need to ask the barber and the problem will be solved. Lets take another example. I want to go on a vacation for 5 days. For that I have to take a leave, select a place for vacation, check how much money is required, check booking dates with hotel, decide mode of transport and make a time-plan of visits to different places during vacation. Now the question arises, "Do I need mathematics?" The answer is Yes. Money required, dates, distance to travel and time-plan need mathematics. This is the real life example of problem-solving in mathematics. For this you have to think, plan, reason out, apply logic and solve the problem systematically.              Writing solution and finding solution are two different scenarios. Writing a solution means solving a problem without th

OBJECTIVES OF TEACHING MATHEMATICS

Image
INSTRUCTIONAL AND BEHAVIOURAL OBJECTIVES   Instructional Objectives  1. These are the statements of measurable learning that is intended to take place as a result of instruction. 2. These are set according to the level of students in a particular class. 3. These are classroom objectives unique to each course or subject. 4. These are derived from the terminal behaviour which the students are expected to display as a consequence receiving instruction. Behavioural Objectives 1. These are the objectives in terms of behaviour of the students. 2. These are description of observable student behaviour related to learning. 3. Behavioural objectives should identify the following    (i) Learner - for whom the objectives are written.     (ii) Behaviour - targeted for change.    (iii) Conditions - under which the behaviour will be performed.    (iv) Criteria - for the acceptable performance of behaviour to occur.   EXAMPLE TOPIC - PYTHAGORAS THEOREM I. COGNITIVE OBJECTIVES    1. To state
