Abstract

This research is a experimental research. The aim of this study was to determine whether the mathematical problem solving ability of students who get learning with exploration method is better than the students who get expository. The population of this study was all students of class VIII SMP in Cimahi. Sampling studies selected by strata. The first step is to choose a school in the town of Cimahi random, then choose two classes at the school by random. The instrument used in this study include the test instrument and the instrument of non tests. Test instruments used in the form of an evaluation sheet consisted of pretest and posttest, whereas the non-test instrument used was the questionnaire. Analysis is conducted quantitative data analysis. The results showed that the mathematical problem solving ability of students who received learning by exploration method is better than the mathematical problem solving ability of students who received expository. Keywords: exploration methods, mathematical problem-solving ability, expository method

Abstract

Tujuan penelitian ini adalah untuk meningkatkan partisipasi aktif mahasiswa pada mata kuliah Analisis Kurikulum dan Materi Pembelajaran Matematika I dengan menggunakan model pembelajaran kooperatif tipe StudentsTeam-Achievement Division (STAD). STAD adalah salah satu tipe pembelajaran kooperatif dengan langkah-langkah meliputi Presentasi kelas, pembagian tim/kelompok, kuis, menentukan skor kemajuan siswa, dan rekognisi tim. Penelitian ini merupaka penelitian tindakan kelas. Subjek penelitian adalah mahasiswa program studi pendidikan matematika Universitas Ahmad Dahlan tahun ajaran 2014/2015 yang menempuh mata kuliah Analisis Kurikulum dan Materi Pembelajaran Matematika I. Objek penelitian meliputi seluruh proses pembelajaran dengan menggunakan model pembelajaran kooperatif tipe STAD dan partisipasi aktif mahasiswa pada mata kuliah Analisis Kurikulum dan Materi Pembelajaran Matematika I. Instumen penelitian meliputi peneliti, lembar observasi, dokumentasi, dan pedoman wawancara. Hasil penelitian menunjukkan bahwa penerapan model pembelajaran kooperatif tipe STAD dapat meningkatkan partisipasi aktif mahasiswa dalam mata kuliah Analisis Kurikulum dan Materi Pembelajaran Matematika I.

Abstract

Tujuan dari penelitian ini adalah untuk menggambarkan penguasaan kemampuan matematika siswa pada materi fungsi, dan mendeskripsikan kemampuan penalaran dan komunikasi pada setiap skor dengan menggunakan rubrik penilaian unjuk kerja. Metode deskriptif kuantitatif digunakan dalam penelitian ini dikarenakan terdapat relevansi pada proses awal sampai kesimpulan yang tersusun. Adapun, sampel yang diambil adalah sebanyak 77 mahasiswa tingkat satu pada salah perguruan tinggi swasta tahun akademik 2014/2015. Berdasarkan hasil penelitian dapat disimpulkan bahwa: 1) kemampuan matematis mahasiswa secara klasikal telah mencapai ketuntasan yang ditandai dengan nilai rata-rata diatas Kriteria Ketuntasan Minimum (KKM), sebaliknya ketuntasan secara individual hanya mencapai 63%. 2) Kemampuan mengkomunikasikan gagasan ke dalam bentuk digram matematika secara keseluruhan hampir lengkap, jelas, efisien, dan tidak ragu-ragu. Sedangkan, untuk kemampuan menggunakan ide-ide dan prosedur penalaran matematika untuk menarik kesimpulan yang telah dibuktikan, secara keseluruhan sebagian besar adalah benar, walaupun, masih terdapat kesalahan perhitungan yang serius. Kata Kunci : penalaran matematis, komunikasi matematis.
