Development and Utilization of Strategic Intervention Material in Chemistry -Learning Area in Science 10

Abstract

INTRODUCTION

In the K -12 Program that we have today in our Enhanced Basic Education Curriculum, Science is in spiral progression to expose the learners to a wide variety of concepts/topics, skills and attitudes until they are mastered as the end point of the program. It is for this vision the researchers believe that it's high time to enlighten the cloudy minds of the students to ensure the mastery of structured science competencies. It is, for this reason, the researchers would like to share her contribution to an optimum method of teaching science, chemistry in particular. They, therefore, embarked on developing and utilizing strategic intervention materials in chemistry that she believes will enhance learning and remedy to the least mastered skills of the students.

METHODS

This paper made use of a descriptive research design with the teacher-made questionnaire as the instrument to gather data. The researcher used the purposive sampling to come up with 60 respondents who got grade 79% and below in their summative test and subjected to study on difficulties encountered in mastering the competency on chemical reactions. Strategic intervention material was developed and utilized for intervention class. The mean Percentage score and T-test were the statistical tools used to determine the significant difference in the score of pre and post-test.

RESULTS

Students encountered difficulties in studying the chemical reaction in Chemistry Learning Area of Grade 10 Science specifically in writing and naming chemical formula as the result of the item analysis of their summative test. Strategic Intervention Material in writing and naming chemical formula was developed and utilized successfully and helped the students in enhancing their skills in writing and naming chemical formula as revealed in the significant difference between the Pre and Post-Test results of the assessment.

DISCUSSIONS

The utilization of strategic intervention material was able to increase the performance of the students in writing and naming chemical formulas. Grade 10 teachers can use intervention materials to help students name compounds and write chemical formulas. Varied strategies in teaching the topic could be applied by the teacher to ensure that students learn and love the subject. This paper implied that teachers can do something for the development and improvement of students' performance. It is just a matter of analysis, reflection, and action.
