Abstract

Siswa sekolah menengah mengalami kesulitan dalam memahami materi matematika yang abstrak, salah satunya bangun ruang sisi datar (BRSD). Alternatif pembelajaran yang dapat membantu kesulitan siswa pada materi bangun ruang sisi datar menggunakan discovery learning berbasis Visual Basic Applications (VBA) Microsoft Powerpoint. Tujuan penelitian untuk menganalis respons ahli terhadap media VBA Microsoft Powerpoint, mendeskripsikan penerapan discovery learning berbasis VBA Microsoft Powerpoint pada materi bangun ruang sisi datar, dan menganalisis respons siswa terhadap penggunaan media VBA Microsoft Powerpoint. Penelitian menggunakan pendekatan kualitatif dengan metode deskriptif. Subjek penelitian adalah satu kelas siswa kelas VIII pada salah satu SMP di kota Bandung. Instrumen menggunakan lembar validasi media dan skala pendapat siswa. Hasil penelitian menunjukkan respons ahli terhadap tampilan media sangat baik, sedangkan respons ahli terhadap sajian materi pada media sudah baik. Penerapan discovery learning berbasis VBA Microsoft Powerpoint memiliki tahap-tahap yaitu stimulation, problem statement, data collection, data processing, verification, dan generalization. Respons siswa terhadap penggunaan media VBA Microsoft Powerpoint sudah baik. Mereka dapat memahami materi BRSD melalui media VBA Microsoft Powerpoint, aktif mengikuti pembelajaran, dan merasa senang.

Abstract

This study aims to increase the mathematical communication skills of students at class VII A on rectangular flat material through the Think-Talk-Write (TTW) approach in SMP Negeri 11 Cimahi. This type of research is CAR or Classroom Action Research  using a model from Kemmis and McTaggart with spiral research, the population sample are all students of class VII A Cimahi 11 Public Middle School consisting of 36 students. This study to be composed of 3 cycles in which each cycle to be composed of the 3 stages that is planning, implementation, and observation reflection, before and after the study was given an instrument test in the form of a description test. In each cycle there is an activity observation sheet. The results of this study indicate that students' mathematical communication skills can be increase through the Think-Talk-Write (TTW) approach application.
