Effectiveness of Multimedia-Based Instructional Materials in Teaching Mathematics for Grade Two Learners

Abstract

INTRODUCTION

Having found out that the pupils have a poor understanding of Mathematics, the researchers thought that using the Multimedia-Based Instructional Materials in teaching Mathematics would be a great help to improve the learner's performance. The purpose of the study is to find out the effectiveness of instructional materials.

METHODS

To find the effectiveness of Multimedia-Based Instructional Materials, the study used the Experimental Method of Research. A pretest before the exposure to the instructional materials and post-test after the exposure to the instructional materials, consisting of thirty items. To find the significant difference between the pre-test and post-test scores of the control and experimental group, an independent t-test was used. To find the significant improvement in the level of performance of the controlled and experimental group, dependent t-test was used.

RESULTS

The control group obtained a mean score of 13.51 in the pre-test with the verbal interpretation of Satisfactory. Similar to the experimental group. The computed standard deviation of 3.61 and 3.62 respectively.In the post-test, the control group obtained a mean score of 21.68 verbally interpreted Satisfactorily. Likewise, the experiment group obtained a mean score of 23.78. The computed standard deviation of 2.63 and 3.76 indicate that the score of both groups is dispersed. The computed t value of -0.22 at a 5% level of significance is less than the critical value of 2.00, thus accepting the null hypothesis in the pre-test. The computed t value of 2.21 at 5% of significance is greater than the critical value of 2.00, thus rejecting the null hypothesis. This means that there is no significant difference in the performance of the controlled and experimental group in the pre-test. However, in their post-test scores, there is a significant difference in their performance. With respect to the performance of the experimental in the pre-test the computed t-value of 82.51. This is greater than the tabular t-value of 1.69 at .05 level of significance. This rejects the null hypothesis stating that there is a significant difference in the performance of the grade two learners before and after the exposure to the Multimedia-Based Instructional Materials in teaching Mathematics.

DISCUSSIONS

There is a marked improvement on the performance in Mathematics of the pupils after they were taught using the Multimedia-Based Instructional Materials in Mathematics. This showed that pupils comprehend and learned better.
