Abstract

Kemampuan visual-spasial sangatlah dibutuhkan dalam memahami berbagai bentuk-bentuk geometri dalam kehidupan sehari-hari. Oleh karena itu guru perlu memahami dan memiliki kompetensi yang baik terkait kemampuan visual spasial. Artikel ini difokuskan pada hasil pelaksanaan workshop PMRI pada materi bangun datar bagi guru-guru KKG Gugus 1 Kec. Bilalang Kota Kotamobagu. Metode pengabdian yang digunakan terdiri dari beberapa tahapan, namun pada atikel ini difokoskan pada tahapan mengembangan dengan metode desian riset yaitu tahap preliminary design, tahap eaching experiment, dan tahap retrospective analysis. Dari hasil workshop tersebut terlihat bahwa guru-guru peserta workshop telah mampu memahami konsep dasar bangun datar menggunakan kemampuan visual-spasial. Selain itu, peserta juga mampu menunjukkan ketertarikan dalam penggunakan pendekatan PMRI pada pembelajan. Di akhir workshop peserta juga telah menghasilkan bahan ajar bangun datar untuk di implementasikan pada pembelajaran matematika di kelas.

Abstract

This research was conducted to improve student learning outcomes in flat-sided building materials taught using the Google Meet application. Classroom Action Research (PTK) was born on class VIII A students of SMP Negeri 2 Tomohon on flat-sided building material. The subjects in this research were 25 students in class VIII A. The implementation of the Google Meet application in PTK activities is carried out in 2 cycles, where each cycle consists of 2 meetings and 1 test, with one meeting lasting 2 x 40 minutes. The results of research in cycle I using the Google Meet application obtained a percentage of student completion of 48%. In cycle II, using the Google Meet application, student completion was 76%. These results show that the Google Meet application can improve learning outcomes.
