Chemture Gamification to Improve Learners' Cognitive Ability on Acid-Base Material

Abstract

This study aims to obtain learning media in the form of games that meet the appropriate category in improving the cognitive abilities of students on acid-base material. The type of research used is Research and Development (R&D) with reference to Thiagarajan's 4D development model and limited to the Development stage. The instruments used include validation sheets, student response questionnaires, student activity observation sheets, and pretest-posttest sheets. The results obtained showed that the validity of the media received a score ≥ 3 with valid criteria, the practicality of the media obtained from the results of the response questionnaire and the observation sheet of students' activities for the response questionnaire obtained a percentage of 92.50% with very practical criteria, while the results of the observation of students' activities at meeting 1 were 91.1% while meeting 2 was 94.4% with very practical criteria. The effectiveness results were obtained from the pretest-posttest results which were analyzed using the classical test and T-test, the analysis results using the classical test obtained a value of 97.06% for the test of students' cognitive learning outcomes with the effective category. The Wilcoxon test results showed that the learning outcomes obtained a significance value (2-tailed) of 0.000 which indicated that there was a significant difference in pretest and posttest learning outcomes. So, it can be concluded that the Chemture game has met the feasible category as a learning media to improve students' cognitive abilities.
