Developing Computer-Based Module Based Ethnoscienceson Merapi Volcano and its Eruption

Abstract

Studying science based on Ethnoscience has many advantages for students. The author develops teaching materials in the form of electronic modules based on Ethnoscience on the Merapi Volcano and its Eruption and to determine the quality and response of students to this product. The e-module development applies the 4D model (define,design, develop, and disseminate) from Thiagarajan. The data was collected in SMPN 2 Kemalang (Kemalang Public Junior High School 2) and SMPN 2 Cangkringan (Cangkringan Public Junior High School 2). The instruments used in the study were interview sheets, expert assessment questionnaire sheets, science teacher assessments, and student response questionnaires data collected by observation, interviews, questionnaire forms, and documentation. Furthermore, the data were analyzed descriptively, referring to Anas Sudijono. The validity of the instrument uses Aiken's V with CVI values ranging from 0.83-1.00. The analysis results show that the average percentage of the overalleligibility of E-Modules by Experts is 94% (Very Good), the feasibility assessment by science teachers is 80% (Good). The average percentage of evaluation by students from SMPN 2 Kemalang (Kemalang Public Junior High School 2) is 80% (Good). At the same time, the results of the average rate of the overall response of SMPN 2 Cangkringan (Cangkringan Public Junior High School 2) students is 82% (Very Good). These results indicate that the product is feasible to use.
