Abstract

This study aims to describe the role of supervision in supporting the optimization of the implementation of the independent training program through the Merdeka Teaching Platform (PMM). The research used a descriptive approach with data collection techniques in the form of a first cycle mentoring questionnaire filled out by two teachers. The research instrument involves six indicators which include teacher involvement in watching training videos, studying materials, completing modules, doing post-tests, completing real action sheets, and obtaining self-training certificates. The results showed that the first teacher obtained a final score of 91% with five indicators achieved, while the second teacher achieved a final score of 100% with all indicators achieved. Supervision played an important role in monitoring teachers' involvement in each stage of the training. These findings provide a concrete picture of the implementation of supervision in supporting the optimization of self-training in PMM.

Abstract

Penelitian pengembangan ini bertujuan untuk mengembangkan media pembelajaran augmented reality (AR) berbasis pendekatan saintifik yang valid, praktis dan efektif dalam meningkatkan kemampuan spasial matematika siswa. Penelitian ini didasari oleh rendahnya kemampuan spasial matematika. Pengembangan dilakukan dengan menggunakan model ADDIE (Analysis, Design, Development, Implementation, Evaluation). Penelitian ini dilakukan di UPTD SMP Negeri 11 Pesawaran pada semester ganjil tahun pelajaran 2025/2026. Rancangan penelitian menggunakan pretest-posttest experimental control group design. Teknik pengumpulan data meliputi wawancara, observasi, angket, dan tes kemampuan spasial matematika. Instrumen penelitian terdiri dari instrumen tes dan non tes (angket dan observasi). Hasil penelitian menunjukkan bahwa media pembelajaran AR tergolong valid berdasarkan penilaian ahli materi sebesar 0,867  dan ahli media sebesar 0,875, praktis berdasarkan respon peserta didik sebesar 0,904  dan respon guru matematika sebesara 0,90. Selanjutnya, media pembelajaran AR efektif berdasarkan uji t pada data N-Gain. Dengan demikian, media pembelajaran AR berbasis pendekatan saintifik memenuhi kriteria valid, praktis dan efektif untuk meningkatkan kemampuan spasial matematika siswa.
