Development of outdoor Science Activity of Biomass Briquette Making as Supplementary Activity in Teaching Heat Transfer

Abstract

The study aimed to develop an inquiry-based lesson plan integrating biomass briquette making as a supplementary activity for teaching heat transfer and related thermodynamic concepts. This aims to enhance Grade 7 learners' academic performance and understanding of students in physics, particularly the concepts of thermodynamics.  The participants of the study were 10 (ten) in-service science teachers and 3 (three) graduate students majoring in physics education, selected purposively. This study employed a Research and Development (R&D) design and utilized a quantitative method with qualitative support in developing the 7E lesson plan. Quantitative data was obtained from the panel of evaluators’ ratings on the developed lesson using the Likert scale and the rubric. Aiken’s V Coefficient was used to assess the content validity of the lesson plan. Qualitative data was obtained through in-depth analysis of the evaluators' comments and suggestions on the developed lesson. The inquiry lesson was enhanced based on the comments and suggestions from evaluators, to ensure that the lesson was aligned with the DepEd learning competencies. The developed inquiry lesson received a “Valid” rating from the 10 In-service Science teachers and 3 graduate students in Physics Education. The positive rating from the evaluators indicates that the lesson with biomass briquette integration has the potential to enhance the Grade 7 academic performance, particularly in comprehending challenging abstract physics concepts such as heat transfer and related thermodynamics concepts. Therefore, this study recommends using inquiry lessons and measuring student learning through pretest-posttest to evaluate their understanding of the topic of heat transfer. Furthermore, explores the long-term impact of the inquiry lesson on learners’ behaviors toward physics and their ability to apply the concepts of thermodynamics in different situations.
