Multimedia pembelajaran merupakan suatu kombinasi dari berbagai media yang dirancang atau diprogram secara terstruktur dan interaktif untuk menyajikan konsep pembelajaran. Hendaknya dipersiapkan multimedia pembelajaranuntuk membantu memudahkan pembelajaran agar siswadapat memahamikonsepdanmerepresentasikan konsep pembelajaran matematika.Tujuan penelitian ini adalah mengembangkan multimedia pembelajaran matematika berbasis teori APOS (aksi, proses, objek dan skema) dan efektivitasnya terhadap pembelajaran pada materi statistika dan peluang yang valid menurut ahli. Efektivitas pembelajaran diukur denganpeningkatan kemampuan representasi matematis dan multimedia dipersepsikan dengan baik oleh siswa. Jenis penelitian ini adalah penelitian pengembangan yang mengembangkan multimedia pembelajaranmatematika dan instrumen yang digunakan adalah angket penilaianahli materi dan ahli desain pembelajaran, angket tanggapan guru dan siswa, persepsi siswa, dan tes hasil kemampuan representasi matematis siswa. Dari hasil analisis tes kemampuan representasi didapat peningkatan kemampuan representasi matematis siswa pada kategori tinggi, berdasarkan uji gain untuk materi statistika skor yang diperoleh 0,7 dan materi peluang skor uji gain diperoleh 1,3. Dan hasil analisis dari angket persepsi siswa didapat persentase 95% menunjukkan kategori “sangat positif”. Dapat disimpulkan multimedia pembelajaran yang dikembangkan sangat baik dan dapat meningkatkan kemampuan representasi matematis siswa. Sehingga multimedia pembelajaran efektiv digunakan oleh guru dan siswa SMA khususnya pada pembelajaran materi statistika dan peluang.Kata Kunci : Multimedia Pembelajaran, Teori APOS, Efektivitas Multimedia learning is a combination of various media that are designed or programmed in a structured and interactive way to present the concept of learning. Multimedia learning should be prepared to help facilitate learning so students can understand the concept and represent the concept of mathematics learning. The purpose of this study was to develop a multimedia learning mathematics based on APOS theory (actions, processes, objects and schemes) and its effectiveness on learning in statistical materials and valid opportunities according to experts. The effectiveness of learning is measured by increasing the ability of mathematical representations and multimedia are well perceived by students. This type of research is development research that develops multimedia mathematics learning and the instruments used are questionnaires for assessment of material experts and expert learning design, questionnaires of teacher and student responses, student perceptions and test results of studentsmathematical representation abilities. From the results of the analysis of the representation ability test obtained an increase in students mathematical representation ability in the high category, based on the gain test for statistical material the score obtained was 0,7 and the probability material gain test score was 1,3. And the results of the analysis of the student perception questionnaire obtained a percentage of 95% showed the category “very positive”. It can be concluded that multimedia learning that is developed is very good and can improve students mathematical representation abilities. So that effective multimedia learning is used by teachers and high school students, especially in learning statistical materials and opportunities.Keywords: Learning Multimedia, APOS Theory, Effectiveness
