Development and Validation of Multimedia Instructional Learning Materials in Earth and Life Science for Senior High School

Abstract

INTRODUCTION

Science and Technology plays a significant role for every learner in building strong pillars for economic and social progress in the future.

However, based on the students performance in the NAT, science is one of the most difficult subjects that give a very low score in the said area in this regard the researcher would like to developed and validate multimedia instructional learning material that could increase the achievement rate on the said subject.

METHODS

A. Participants of the Study 5 Science Teachers and 5 Master Teachers of Science for validation purposes. 20 Grade 11 students of OBBNHS-SHS for the experimental group 20 Grade 11 students of OBBNHS-SHS for controlled group

B.Data Gathering Methods Utilization and validation of a questionnaire checklist by the 10 experts Pre-test and Posttest which has been developed by the researcher

C.Plan for Data Analysis Experimental research design utilizes a survey method in validating the Developed Multimedia Instructional Learning Materials The researcher used percentage and ranking to determine the least mastered competency in Earth and Life Science

RESULTS

The evaluation of Science teachers in the entire variable has a very in height extent on all variable. The result on pre-test and post-test has 0.05 level of significance, and 59 degrees of freedom, the computed t-value of 78.0 is greater than the critical t-value of 2.0. This means that the null hypothesis is rejected and that there is a significant difference in the performance of the students before and after using the developed multimedia instructional learning materials.

DISCUSSIONS

This implies that the Develop Multimedia Instructional Learning Materials is an effective tool in improving the students’ performance and could be developed base on the list of mastered topic in improving the students’ performance in Science. The following recommendations were made:

1.Strengthen the validity and reliability of the study by increasing the number of validators; and2.Additional interactive activities for the student.
