Abstract
This is an Experimental research entitled Effectiveness of Experimental
Verification in Teaching Geometry. The objectives of the study were ‘to compare the
achievements of the students taught by using experimental verification method and
traditional method in geometry’ and ‘to analyze the effect of experimental verification
in learning mathematics’.
A pretest, posttest, equivalent group design was adopted to achieve the
objective of the study. For this, two groups were selected by stratified sampling
method from two government schools of Syangja district, which were similar in
socio-economic status and result of the students from each school 20 students were
selected for a sample of the study. In order to make the groups comparable a pretest
was administered to both group which resulted that the groups are comparable at 0.05
level of significance. Both the experimental and control group were taught by
researcher himself for 2 weeks by using and without using experimental verification
respectively. Researcher taught the chapter ‘area of triangle and quadrilaterals and
regular polygon’ of mathematics textbook of grade VIII prescribed by government of
Nepal. Student’s behavior was observed by the researcher during the experimentation.
After the completion of experimentation, an achievement test was administered on the
both group. The result of test was analyzed by using t-test at 0.05 level of
significance.
It is found that the mean achievement score of students taught by using
experiment verification is better than the mean achievement score of the students
taught by without using experiment verification. Hence there is significant difference
between the achievement of students taught by experimental verification and
traditional method. From the observation, it is concluded that almost of the students
taught by using experiment verification were very active, laborious, regular,
concentrative and competitive.
