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)Ã‚Â 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.

This research and development aims to develop LKPD based on open-ended and test its effectiveness on critical thinking skills in mathematics. This development phase begins with research and information gathering, planning, initial product form development, initial field testing, major product revisions, and main field testing. The subjects of this study were the eighth grade students of Al-Huda Jati Agung Junior High School in the academic year 2019/2020. The effectiveness test was conducted to determine the effectiveness of LKPD on the ability to think critically mathematically. The LKPD based on the open-ended developed was suitable for use in the excellent category based on the results of the validation of two expert validators. Preliminary field trial results indicate that LKPD is included in the good category. Field test results show that the average increase in students 'critical thinking skills in mathematics using LKPD on an open-ended basis is higher than the increase in average students' critical thinking skills in mathematics that do not use LKPD based on open-ended, so it can be concluded that LKPD based on open-ended effective for improving students' critical thinking math skills.
