Developing ChemonDro Application on Redox Concepts to Improve Self-Regulated Learning of Students

This research aimed to produce an android-based learning media called ChemonDro (Chemistry on Android) application on the concepts of oxidation-reduction (redox) reaction and to identify the improvement of students' self-regulated learning. The development research procedures were adapted from the Gall, Gall & Borg development model consist of four phases: planning, product development, formative evaluation and revision, and summative evaluation. ChemonDro validations were conducted by two lecturers. ChemonDro assessments were conducted by five chemistry teachers and five peer reviewers. ChemonDro evaluations were conducted on senior high school students grouped into one-to-one evaluation on 6 students, small group evaluation on 10 students, and field test evaluation on 32 students. Field test evaluation was conducted to determine the effect of ChemonDro used on self-regulated learning. Instruments used in this study include a questionnaire of media assessment and a questionnaire of self-regulated learning. The media assessment questionnaire was given for a media expert, a materials expert, reviewers, peer reviewers, and students. Questionnaire of students' self-regulated learning was given to students before and after the learning process. The results showed that the ChemonDro on redox concepts developed can improve the chemistry self-regulated learning of senior high school students.
