Color-Coded Clam Shells: Localized Learning Material in Increasing the Mastery Level on Bohr's Atomic Model

Abstract

INTRODUCTION

Science is a core element in elementary and secondary levels. It aims to develop scientific literacy among students and prepares them to actively participate in the natural world. Based on the result of the First Quarter Examination in Science, Grade 9 students got the lowest MPS of 38.1 %. It also shows that based on the diagnostic test for the Second Quarter, the least mastered topic includes the Bohr atomic model, with students having difficulty in understanding the concept with pure lectures and abstractions. The use of localization in teaching science will be a great help to students since it involves materials that are available in their locality. It is along this line of thought that the researcher conducted research for the purpose of determining the effect of using Color-Coded Clam Shells as a Localized Learning Material in increasing the mastery level on Bohr Atomic model of Grade 9-Fortitude students at Linga National High School.

METHODS

The pretest and posttest were administered to Grade 9-Fortitude students. The scores in the pretest and posttest were gathered and statistically treated. The researcher used the descriptive survey method. To obtain the data needed to determine the effects of Color-Coded Clam Shells as a Localized Learning Material in Bohr’s Atomic model, a researcher-made questionnaire is constructed. A 5-point Likert-type scale is used, ranging from strongly agree to disagree, to determine their responses concerning the matter mentioned above.

RESULTS

The result of the assessment showed the pretest result with a weighted mean of 2.48, SD of 0.83, and SE Mean of 0.13 as compared to the post-test which has a Mean of 9.64, SD of 0.62, and SE Mean of 0.10. A significant mean difference of 7.16 manifested that using Color Coded Clam Shells has a significant increase in the mastery level of Bohr's atomic model of Grade 9-Fortitude students at Linga National High School. The researcher found out that Grade 9-Fortitude students enjoy using color-coded clam shells in the activity. The weighted mean of 4.615 with a verbal interpretation of strongly agree indicates that the use of color-coded clamshells has a great impact on the students.

DISCUSSIONS

Based on the result, the Color Coded Clam Shells, as localized learning material, increase the mastery level of Grade 9-Fortitude students on Bohr's atomic model. The researcher highly recommends the use of these clam shells as localized learning material to science teachers and they should utilize it to other topics so the students can easily understand science concepts.
