PENGEMBANGAN MEDIA INTERAKTIF UNTUK MENINGKATKAN KEMAMPUAN KOMUNIKASI MATEMATIS SISWA SMP KELAS VIII MATERI PERBANDINGAN

This research is motivated by the rare development of interactive media based on Adobe Flash software that focuses on improving students' oral mathematical communication skills. The purpose of writing this paper is to find out how to develop interactive media to improve valid and effective oral mathematical communication skills of junior high school students. Data were collected in the Lamongan area with the subjects of class VIII junior high school students who were randomly selected. The method used is descriptive qualitative with data collection techniques carried out by giving tests and interviews. Based on the results of the field trials, it was found that the interactive media that had been developed by the researcher had met the criteria for a good and effective learning tool by fulfilling the following requirements: (1) valid, that is, it had met the valid criteria.
