Reflect It-on (Rio) Device: Innovative Instructional Materials in Optics

Abstract

INTRODUCTION

Teaching strategies used by teachers are key determinants in the performance of students. Teacher must use appropriate instructional materials to stimulate and experience the reality in the classroom. Instruction must be designed in such a way that it address the needs of the learners and achieve high level of performance. Utilization of innovative materials such as Reflect it-on device specifically in teaching image formation in concave mirror will support the students’ procedural skills and knowledge by using authentic materials that are locally available. It also provides teachers’ ability to transform traditional strategies into a current trend in teaching the lessons.

METHODS

The study utilized the experimental method research design in gathering the essential information that answered the problems presented. The respondents of the study were 75 Grade 10 students of Pedro Guevara Memorial National High School. The questionnaires served as the main tool which help solicit responses from the student. Same set of pre-test and post-test was served to the students to compare part groups and measure the degree of change occurring as a result of treatments or interventions. Mean, standard deviation and T-test statistics were used to measure the significant effects of utilizing Reflect It-On (RIO) device as innovative instructional materials in optics.

RESULTS

The findings revealed that the three groups showed fair level of performance based on their pre-test mean scores thus both groups of respondents are almost of the same level of understanding and performance. Based on the post-test mean scores, experimental group C got the highest mean. Outstanding performance was obtained by experimental group C; while Satisfactory performance was obtained by experimental group A; Very satisfactory performance was shown by experimental group B. Significant difference was noted on the students' level of performance based on the pretest and post test scores.

DISCUSSIONS

The result implied that the use of Reflect It-On device as an Innovative Instructional Material is effective in teaching the lessons in optics. Furthermore, the result of the study also supports the students' procedural skills and knowledge by using authentic materials that are locally available. Moreover, the study implied that utilization of Reflect it-On device has an important role in the teachers' ability to transform traditional strategies into current trends in teaching the lessons in optics.
