A Supplemental Module to Improve the Conceptual Understanding of Hydrocarbons of Selected Grade 9 Students

Abstract

For so many years, instructional materials have been developed and utilized in different subject areas, but still the use of effective instructional materials in teaching has long been a concern. This study attempted to design and evaluate a supplemental module which aims to determine whether the students will have a better conceptual understanding of hydrocarbons. The subjects of the research were sixty (60) students of Muntinlupa Business High School during the school year 2015 –2016. The students were divided into two (2) groups: thirty (30) of them had undergone learning with the use of the module marked as Group 1 and the other thirty (30) had undergone learning without the use of the module marked as Group 2. Researcher-made pre-test and post-test were the research instruments. The findings obtained from the quantitative data showed that there is a significant difference in the conceptual understanding of the students about hydrocarbons particularly those students who had undergone learning with the use of the module compared to the students who had undergone learning without the use of the module. This suggests that the supplemental module significantly contributed to the conceptual understanding of students about hydrocarbons. The use of the module, indeed, improved the quality of instruction making the entire teaching-learning process more meaningful and relevant.
