Ocean wave energy learning project (OWELP): a program to communicate alternative energy technology

Abstract

ABSTRACT Background Efforts to communicate the use of alternative energy as a solution to the continued scarcity of world energy were continuously carried out. However, not all countries with abundant potential for alternative energy sources focus on this, resulting in a lack of human resources who study the field of alternative energy. Purpose This study aims to communicate the topic of ocean wave energy and its technology as an alternative energy source through the Ocean Wave Energy Learning Project (OWELP) program. Sample This study utilized a purposive sampling method on 31 pre-service physics teachers taking environmental physics courses at one of the universities in a small area in Indonesia. Methods This study utilized a mixed-method research of explanatory design. The first stage of quantitative research used a pre-experimental approach with a one-group pretest-posttest design. Data collection instruments were in the form of knowledge test sheets consisting of essay questions, observation sheets on the implementation of lecture programs, rubrics of product assessment, and interview sheets. The next stage is the phase of collecting qualitative data to explain the results obtained in the quantitative phase through interviews. Quantitative data on learning outcomes were analyzed using the Wilcoxon test, a further test of effect size, and N-gain analysis, while the qualitative data were analyzed descriptively. Results The results of the data analysis showed that the OWELP program positively influenced students’ mastery of the concepts. The OWELP program also effectively increased pre-service physics teachers’ mastery of ocean wave energy concepts as an alternative energy source. In addition, the OWELP programcan indirectly equip various skills such as critical thinking, creative thinking, problem-solving, collaboration, and communication. Conclusion The OWELP program can be used to improve pre-service physics teachers’ mastery of the concept of using ocean wave energy as an alternative energy source.
