The development of instructional media chemo-edutainment (CET) based chemistry ludo game on atomic structure topic for 10^th grade senior high school students

This study aims to develop a valid and practical instructional media based on Chemo-Edutainment (CET), specifically a chemistry ludo game for atomic structure topic. This study used Research and Development (R&D) method with 4-D model, consists of Define, Design, Develop and Disseminate. This study performed validity and practicality test. The instructional media validated by three lecturers from chemistry department FMIPA UNP and two chemistry teachers from MAN 1 Payakumbuh. The validity and practicality questionnaire were used as the instruments in this study. The data collected by disseminating the questionnaire then analysed using Kappa Cohen formula. Based on the data, the validity level of the developed instructional media was 0.77 and the practicality level at 0.85 (from teachers) and 0.94 (from students). This result means that the developed instructional media can be used in learning atomic structure topic.
