Abstract

Practicum is often applied in acid-base topics and makes learning more meaningful because students can directly observe the chemical processes that occur during the practicum. This research aims to produce an acid-base practicum e-module based on STEM-REACT as a solution to the problems experienced by students during an acid-base practicum due to the lack of learning media to complement the practicum. The development of the e-module used the Borg & Gall research and development model. The learning stages in the e-module are arranged based on the REACT learning strategy, and the STEM aspects in the e-module include (1) Science, applying acid-base concepts in the practicum, (2) Technology, using soil meter and creating practicum videos, (3) Engineering, designing and conducting practicum according to systematic work steps, (4) Mathematics, analyzing and solving problems mathematically. The validation test percentages by content and language experts ranged from 80-100% and media experts ranged from 81-92%, with reliability values of 0.9268 for content and language experts, and 0.9538 for media experts. Small-scale e-module trials obtained a value of 63-100%, while large-scale trial results ranged from 67-100%, and teacher trial results ranged from 75-100%. Based on the assessments^ results, the e-module developed is suitable to use in chemistry learning.
