Development of E-Module based on Phenomenon-based Learning in Thermochemistry to Facilitate Student during Covid-19 Pandemic

Covid-19 pandemic has affected psychological condition and alteration of human behavior. This also has an impact on education system in Indonesia. To continue the learning process, an effort is needed by conducting an online learning. To bolster up the implementation of online learning processes, e-module is needed to be used as online teaching material. This study aims to develop an e-module based on phenomenon-based learning in Thermochemistry material which is feasible to be implemented in the learning processes in school by offline and online. This study used a research and development (R & D) study using Plomp model. Data collection techniques used expert validation questionnaires and user response questionnaires. Feasibility level of e-module based on phenomenon-based learning in thermochemistry seen form the function aspect as a teaching source based on the experts and users' research is 98.3%; hence, the e-module based on phenomenon-based learning which developed is feasible to be implemented as the teaching sources. The e-module based on phenomenon-based learning is tested to 10 high school students, and then they are requested to fill out the respondent questionnaires and the results are 90.13%. The advantages of e-module based on phenomenon-based learning are: (1) equipped with a description of phenomena-based material found in everyday life; (2) equipped with critical questions to improve students' critical thinking skills; (3) equipped with learning videos as a support for students to repeat the teaching material; (4) and it can be used anywhere and anytime.
