Transcript of INDUCTIVE-DEDUCTIVE METHOD OF TEACHING MATHEMATICS

Inducto- Deductive Method = Inductive Method + Deductive Method
A Child Observes a rising of sun and getting of darkness after the setting of sun This He Observes everyday…
CONCLUSION:
“The Sun Rises Everyday And Also Sets Everyday”
A Child Eats
Green Apple
EVERYTIME and Feels its sour taste.
CONCLUSION:
CONCLUSION: ALL THE GREEN APPLES ARE SOUR IN TASTE
What is INDUCTIVE METHOD???
INDUCTIVE-DEDUCTIVE METHOD OF TEACHING MATHEMATICS
INDUCTIVE METHOD Principles:

Maxims : proceeding from
Concrete to Abstract,
Particular to general,
Example to formula.
Direct Experiencing.
Conclusions are based on repetition at many times.
Child concludes after each observation.
Child generalizes after many observations
A child measures each and every triangle and concludes that, “Sum of angles in every triangle is equal to 180 degrees”
CONCLUSION:
CONCLUSION:

He Generalises that, (1st Term+2nd Term)2 = (1st Term)2 + 2 (1st Term)(2nd Term) + (2nd Term)2
c) Simple Interest of Rs. 600/- for 4 years at 3% p. a.
Simple Interest= 600x4x3/100= Rs. 72

WHAT WILL BE A CONCLUSION???
MERITS:


 Scientific Method
 Content becomes crystal clear to students , as they develop on their own formula/ laws / Principle
 Based on Actual Observation and Experimentation .
 Thinking is Logical
 Suitable for beginners
 Increases Pupil – Teacher Relationship
 Home Work is reduced.
DEMERITS:


Not suitable for all topics

Time Consuming Method

Laborious Method

Not Suitable for all types of students

Un- prepared teacher can not make use of this method
DEDUCTIVE METHOD
a method of reasoning by which concrete applications or consequences are deducted from general principles or theorems are deduced from definitions and postulates
“ALL THE GREEN APPLES ARE SOUR IN TASTE” The child may be told that he should never eat the green apple because they are sour. Afterwards he may verify this facts by tasting green apples.
PRINCIPLES :
Maxims : Proceeding from
Abstract to Concrete,
General to Particular,
Formula to Examples.
Students are given formula/rules/laws/princ iples directly .
They solve problems using them.
1)EXAMPLES: •Students are told that the sum of angles(3) in a triangle is 180degrees. • Then the students verify the same . •Students will conclude that “sum of angles of triangle is equal to 180 degrees”
3)The Teacher may announce that today he is going to learn Simple Interest. He will then give the relevant formula. i.e. S . I . = p x r x t/ 100 And Asks the Student to solve the Problem based on this formula
MERITS:

Time Saving Method
 Suitable to all topics
 Suitable to all Students
 Glorifies Memory
.Useful at Revision Stage
 Enhances Speed and efficiency
 Mostly Used at Higher Stage level
DEMERITS:

Unpsychological Method
 No Originality and Creativity
 Blind Memorization
Educationally Unsound.
 Students are Passive Learners.
 Reasoning is not clear
A Child Observes a rising of sun and getting of darkness after the setting of sun This He Observes everyday…
Inductive approach is advocated by Pestalaozzi and Francis Bacon
In this we first take a few examples and greater than generalize.
The children follow the subject matter with great interest and understanding. This method is more useful in arithmetic teaching and learning.
inductive instruction is a much more student-centered approach and makes use of a strategy known as ‘noticing’.
3. Square of an odd number is odd and square of an even number is even.

Solution:
Particular concept:
12 = 1 32 = 9 52 = 25 equation 1
22 = 4 42 = 16 62 = 36 Equation 2
General concept:
From equation 1 and 2, we get
Square of an odd number is odd
Square of an even number is even.
DEDUCTIVE METHOD
A child is told “The Sun Rises Everyday And Also Sets Everyday!” This fact child verifies by daily observation
