Masalah yang ditemui di lapangan adalah kemampuan berfikir kritis matematis peserta didik yang belum optimal. Kemampuan berfikir kritis matematis peserta didik dapat ditingkatkan dengan menggunakan perangkat pembelajaran berbasis kecerdasan majemuk. Tujuan dari penelitian ini adalah untuk mengetahui proses dan hasil pengembangan perangkat pembelajaran berbasis kecerdasan majemuk dalam meningkatkan kemampuan berfikir matematis peserta didik. Jenis penelitian ini adalah penelitian pengembangan (Development Research). Model pengembangan yang digunakan adalah model Plomp yang terdiri dari tiga fase yaitu fase investigasi awal (preliminary research), fase pengembangan atau pembuatan prototype (development or prototyping phase), dan fase penilaian (assessment phase). Pada bagian ini hanya membahas penelitian pada investigasi awal (preliminary research). Instrument yang digunakan pada fase investigasi awal (preliminary research) adalah angket peserta didik, pedoman wawancara guru, catatan lapangan, lembar soal tes pendahuluan. Hasil analisis data pada fase investigasi awal (preliminary research) menunjukkan bahwa 1) rendahnya kemampuan berfikir kritis matematis, 2) kemampuan peserta didik bervariasi, 3) cara belajar peserta didik bervariasi, 4) perangkat yang digunakan guru kurang memfasilitasi peserta didik untuk meningkatkan kemampuan berfikir kritis matematis peserta didik, 5) kurang terlibatnya peserta didik dalam proses pembelajaran, 6) peserta didik sulit memahami Bahasa yang digunakan pada sumber belajar.The problem encountered in the field is that students' mathematical critical thinking skills are not satisfying yet. Students' mathematical critical thinking skills can be improved by using multiple intelligence-based learning tools. The purpose of this study was to determine the process and the results of the development of learning tools based on multiple intelligence in improving students' mathematical thinking skills. This is a development research. The development model used is the Plomp model which consists of three phases, namely the preliminary research phase, the development or prototyping phase, and the assessment phase. This thesis only discusses the preliminary research phase. The instruments used in this research are student questionnaires, teacher interview guidelines, field notes, preliminary test question sheets. The results of data analysis in the preliminary research phase showed that 1) there is a lack of mathematical critical thinking skills, 2) Students have various kinds of abilities, 3) There are differences in students’ learning styles, 4) There is a lack of teaching tools used by the teacher so that the students are not able to improve their critical thinking mathematically, 5) there is lack of students participation in the learning process, 6) It is difficult for students to understand the language used in the learning resources.

This research aimed to develop local instruction theory that is valid, practical, and effective to help elementary school students developing their mathematical problem-solving skills. Therefore a sequential activityis design on dailybasis to encourage students to develop their ability to solve mathematical problems, especially on the topic division. To achieve the goal, realistic mathematics approach was implemented to grade three elementary students in the learning process. The designed activities were validated by experts on the aspects of mathematical contents, language, didactical process based on realistic mathematical approach. Data were analyzed with descriptive statistics and parametric statistics. The validation results show that the local instruction theory was valid, and the implementation shows that the local instruction theory is practical and effective in improving students' mathematical problem-solving skills.

Kemampuan berpikir kritis merupakan kemampuan yang diperlukan dalam perkembangan dunia saat ini. Namun, kemampuan berpikir kritis peserta didik masih rendah. Halminimdisebabkan peserta didik masih ketergantungan kepada guru dalam menerima informasi serta pembelajaran yang terjadi di kelas belum memfasilitasi kemampuan berpikir kritisnya dalam bidang geometri. Untuk itu dikembangkan lembar kerja peserta didik berbasis teori Van Hiele yang diharapkan dapat membantu mengatasi masalah tersebut. Tujuan dari pengembangan produk ini yaitu untuk mmenghasilkan mlembar kerja peserta didik berbasis teori Van Hiele yang efektif dalam meningkatkan kemampuan berpikir kritis matematis peserta didik kelas VIII SMPN 13 Padang. Subjek penelitian ini adalah peserta didik kelas VIII SMPN 13 Padang. Model pengembangan yang digunakan diadaptasi dari model Plomp. Ada tiga tahapan pada model ini yaitu preliminary research, prototype phase, and assesment. Pada penelitian ini difokuskan melihat keefektifan produk pada tahap assesment. Tahap assesment dilakukan pada uji lapangan (field test) yang terdiri dari 30 peserta didik selama 6 kali pertemuan. Keefektivan produk dilihat setiap pertemuan pada tahap field test serta tes yang diberikan pada akhir pertemuan. Hasil penelitian diperoleh bahwa kemampuan berpikir kritis matematis peserta didik cenderung meningkat selama enam kali pertemuan serta tes akhir juga menunjukkan bahwa terjadinya peningkatan sebesar 73,33%.
