Abstract
Penelitian ini bertujuan untuk mengembangkan bahan ajar transformasi geometri yang berorientasi pada kemampuan berpikir kritis siswa. Penelitian ini merupakan penelitian pengembangan yang mengikuti tahapan R&D (Brog & Gall, 1989). Ujicoba lapangan dilakukan pada siswa kelas XI SMA Fransiskus Bandar Lampung tahun pelajaran 2018/2019, dengan XI-A1 sebagai kelas eksperimen dan kelas XI-A3 sebagai kelas kontrol. Perbedaan perlakuan dari kedua kelas adalah penggunaan bahan ajar transformasi geometri. Pengumpulan data menggunakan lembar validasi untuk menentukan validitas bahan ajar, angket respon siswa dan praktisi untuk menentukan tingkat kepraktisan dan instrumen tes kemampuan berpikir ktitis siswa untuk menentukan kefektifan bahan ajar setelah pembelajaran yang kemudian dianalisis dengan uji perbedaan rata-rata. Hasil penelitian ini adalah pengembangan bahan ajar tranformasi geometri yang dikembangkan valid, praktis, dan efektif. This research was aimed to develop a geometry transformation learning material that is oriented to students' critical thinking ability. This research was an development research that followed R&D stages (Brog & Hall, 1989) until the main field test. The field-testing was conducted on grade XI students of SMA Fransiskus Bandar Lampung academic year 2018/2019 where XI-A1 was chosen as the experiment class and XI-A3 as the control class. The difference in treatment between these two classes was in the using of the geometry transformation learning material. Data were collected using the validation sheet to determine the validity level, the students' response questionnaire to determine the practicality level, and the students' critical thinking ability test instrument to determine the effectivity of the learning material after the learning process. Afterwards, data were analyzed by the difference in mean test. It can be concluded from the research result that the developed geometry transformation learning material was valid, practical, and effective.
