Development of chemistry e-module flip pages based on chemistry triplet representation and unity of sciences for online learning

The digital module can be used as a solution in online learning during the Covid-19 pandemic. The purpose of this study was to develop and evaluate a Chemistry e-Module Based On Chemistry Triplet Representation and Unity of Sciences. Research and development were conduct to developed this e-module. The steps were: (1) research and information collected; (2) planned; (3) developed a primary form of product; (4) preliminary field-tested; (5) main product revision; (6) main field-tested; (7) operational product revision; (8) operational field-tested; (9) final product revision; (10) dissemination and implementation. Pre-test post-test control group design was applied to see the effectiveness of e-Module on critical thinking skills. Data were collected using test and non-test methods. The research subjects were students of the Chemistry Education Department, UIN Walisongo. Chemists and multi media experts have done the validation to test the initial quality of the products and give a feedback for the product improvement. The results of the validation test from experts reviews obtained a mean score of 3.85 from a maximum score of 4, which indicated that the e-Module was in the Eligible category. The media expert’s assessment got a mean score of 4.0 from a maximum score of 5 which means that the e-module was in the Appropriate category in media aspects. The e-Module got a mean score of 3.64 from the highest score of 4, which means that the e-module developed was in the very feasible category according to students. T-test results showed that there were differences in N-gain score between control and experimental group. It has been proved to be significantly different (sign test from SPSS showed < 0,05), with the mean score of the experimental class being higher than the control class. The Control group achieved an N-gain score of 0.53 (moderate category) otherwise experimental group achieved 0.80 (high category) which was higher than the control group.
