Abstract
Problem
solving consists
of using generic or ad
hoc methods, in an orderly manner, for finding solutions to
problems. Some of the problem-solving techniques developed and used in
artifical intelligence, computer science,engineering,
mathematics, or medicine are related to mental problem-solving
techniques studied in psychology.The study was conducted in G.V.H.S.S
Nedumkandam. The 22 students of 8 C were selected as the subjects for the
study.

1. INTRODUCTION
Problems are a central part of
human life. Everybody in this world, from birth onwards faced with some
problems. Any single work of in the life situation is in a sense of problem,
simple or complex requiring solution. One of the objective of the modern
education is to develop problem solving skills.
Problem solving ability is sometimes
reffered to as reasoning.One should be trained to reason in a systematic and
orderly manner to find solutions to problems. Solutions to problems are drawn
out of experiences.
The problem solving behavior involves
convergent and divergent thinking. The former involves generalization and the
latter discrimination or differenciation. The problem solving behavior results
from the leaving of new and more complex higher order rules. The present
experiment minimizes the verbal component of thinking, while one arrives at a
solution for the problem.
After identifying the existence of
a problem,we must define it’s scope and goals. Problem solving does not usually
begin with a clear statement of the problem;rather most problems must be
identified in the environment ;then they must be defined and represented
mentally.
Psychologists have described
the problem solving process in terms of a cycle. The cycle constitute following
stages in which the problem solver must:
1) Identify the
problem.
2) Define and
represent the problem mentally.
3) Deveop
solution strategy.
4) Organise
his/her knowledge about the problem.
5) Allocate
mental and physical resources for solving the problem.
6) Monitor
his/her progress towards the goal.
7) Evaluate the
solution for accuracy.
Problem :-
To study the process of
reasoning through analysis of the subject behavior while solving similar
problems of increasing difficulty.
2. METHOD
a) Subjects:
There are 22
children of the class 8 C in G.H.S.S Nedumkandam is selected as subject s for the problem
solving.
b) Apparatus:
Five wooden blocks varying in size with a stand having 3 poles and stop
clock.
c) Procedure:
Three positions below
labeled A,B,C were used. The poles of wooden blocks arranged in the order from the
largest at the bottom and the smallest was placed at the top. Then the subject
was seated comfortably. The following instructions were given.
“You are to move this wooden blocks placed in the pole A to either pole
B or C ,moving only one block at a time, and never placing a large block upon a
smaller one. Use all the three positions in making the moves. Try to think ahead
of each time and formulate mentally a plan of actions before you start to
moving the blocks. If it seems impossible to form a plan you may start with
trial and error and formulate a plan as you work alone. Ready go.”
A. B. C.
The experiment was started with the
simplest problem of 2 blocks, the number
of moves for each problem was restricted. The highest level of the problem was
with the 5 blocks. For each child the time taken was note down using stop clock. When the subject
succeed in two consecutive trials in a particular problem , she was asked to go
to the next higher problems. When the subject failed to solve the problem in
two consecutive trials, the experiment was stoped. Soon after the experiment,
introspective report was collected and was recorded in after in the table.
3. RESULTS
The
table shows the group data in the problem solving experiment.
4. DISCUSSION
The
present experiment has been conducted to study the process of reasoning through
analysis of the subject’s behavior while solving similar problems of increasing
difficulty. Problem solving reffers to an individual’s ability to find out the
solutions to the problem or finding out
all the possible alternatives for the same problem. Since we are living in a
competitive world, one of the important aim of education is to develop a
problem solving ability in an individual and hence it is imparitive to analyse
the problem solving ability of an individual.
On analysis of the
group data, it is found that all the 22 subjects in the group have taken the
minimum of the 2 trials for the two block
problem. The subject JPP has taken the highest time of 23 seconds and the subject NS has taken the
lowest time of 6 seconds. The subject AB has taken the highest time of 25
seconds, and the subject SS has taken the lowest time of 15 seconds for three
block problem.
The subject SB has taken the highest time of 38 seconds and the subject AV has taken
lowest time of 33 seconds for four block
problem. Except AV and SB all others failed to complete the four block problem.
5. CONCLUSION
i.
The majority of the
subjects in the group able to solve the the problem with 3 blocks.
ii.
Individual differ in the
problem solving ability.

Reflective
Journal:
It’s very interesting to do the problem
solving experiment among the students. They are very interested to the
experiment. Some of the students succeed in 4 block probem. But none of them
succeed in 5 block problem. All of them
have a competition mentality towards the problem.
