<![CDATA[This research aimed to develop an animation media of particles matter based on chemistry representation for student in junior high school; describe the characteristics of developed animation media; describe the teachers’ feedback and students response to an animation media of particles matter based on chemistry representation; and knowing the obstacles encountered when developing an animation media of particles matter based on chemistry representation. This research use the Research and Development method. The results showed that teachers’ responses of the developed animation media in the content’s suitability aspect were 93% and in the readable aspect were 94%. All of the teachers’ responses were very hight category. The result showed that students’ responses of the developed animation media in the content’s readable aspect were 91,69% and in the attraction aspect were 86,70%. All of students’ responses were very high category. Penelitian ini bertujuan untuk mengembangkan media animasi partikel materi berbasis representasi kimia untuk siswa pada tingkat Sekolah Menengah Pertama; mendeskripsikan karekteristik media animasi yang dikembangkan; mendeskripsikan tanggapan guru dan siswa terhadap media animasi partikel materi berbasis representasi kimia; dan mengetahui kendala-kendala yang dihadapi ketika mengembangkan media animasi partikel materi berbasis representasi kimia. Metode penelitian yang digunakan adalah metode Penelitian dan Pengembangan. Hasil penelitian menunjukkan bahwa tanggapan guru terhadap media animasi yang dikembangkan pada aspek kesesuaian isi adalah 93% dan keterbacaaan sebesar 94%, semua termasuk kriteria sangat tinggi. Menurut tanggapan siswa pada aspek keterbacaan adalah 91,69% dan kemenarikan sebesar 86,70%, semua termasuk kriteria sangat tinggi.Kata kunci: media animasi, partikel materi, representasi kimia]]>
