The Development of E-Module Based on Guided Inquiry Learning on the Fundamental Laws of Chemistry Topic for X Grade

Abstract

This study aimed to produce an e-module based on guided inquiry learning on the fundamental laws of chemistry topic that is valid and practical for x grade. The type of this research was Research and Development (R&D) with a four-D (4D) development model that consists of four stages; (1) define, (2) design, (3) develop, and (4) disseminate. This research was limited to the validity and practicality test. The validity test was carried out by 8 experts and the practicality test was carried out with a limited trial on teachers and students conducted at MAN 2 Kota Payakumbuh. The research instrument was used in the form of a validity and practicality questionnaire which was analyzed using Aiken's V formula. Data analysis obtained an average validity of content was 0.92 with a valid category, while the average validity of the media was 0.95 with a valid category. Based on the practicality test of teachers and students, the percentages are 0.97 and 0.87, respectively, in the very practical category. Based on the study results, it can be said that the e-module based on guided inquiry learning on the fundamental laws of chemistry topic for x grade was valid and practiced to use in the learning process.
