Development of interactive media based on mathematics with HOMTS and learning by doing orientation

Mathematics learning needs to act as a bridge between students’ everyday culture and mathematics in school. The digital age requires teachers to develop innovative interactive media that contains hands-on activities and can improve higher-order thinking skills. This research is a Research and Development (R&D) of interactive media, namely lectora inspire based on ethnomathematics with HOMTS orientation and learning by doing. The steps in this research are (1) potential problems; (2) data collection; (3) product design; (4) design validation; (5) design revisions; (6) product trials; and (7) product revisions. The results showed that lectora inspire based on ethnomathematics with HOMTS orientation and learning by doing is appropriate to be used as interactive media in learning linear equation systems for senior high school students.
