Abstract

ABSTRAKMasalah penelitian ini adalah rendahnya kemampuan penalaran logis matematis siswa. Penelitian ini bertujuan untuk mendeskripsikan efektifitas pembelajaran kooperatif ditinjau dari peningkatan kemampuan penalaran logis matematis siswa SMA. Penelitian ini berbentuk quasi eksperimen dengan desain kelompok kontrol pretes-postes. Sampel penelitian ini berjumlah 38 siswa yang diambil secara proposive sampling dari dua kelas siswa pada suatu sekolah swasta di Kabupaten Halmahera Selatan. Penelitian ini mempunyai dua variabel, yaitu: pembelajaran kooperatif sebagai variabel bebas, dan kemampuan penalaran logis matematis siswa sebagai variabel tak bebas. Intrumen yang digunakan untuk pengumpulan data adalah tes kemampuan penalaran logis matematis. Data primer yang diperoleh dari penerapan instrumen tes tersebut, dianalisis menggunakan statistik uji One-Sample Test pada taraf signifikansi α=5%. Hasil penelitian menunjukkan bahwa kemampuan penalaran logis matematis siswa SMA melalui pembelajaran kooperatif mencapai 74,97% dalam kualifikasi baik dan peningkatannya mencapai 0,72 tergolong tinggi.Kata Kunci    :   Penalaran Logis Matematis, Kemampuan Penalaran Logis Matematis Siswa, dan Pembelajaran Kooperatif  ABSTRACTThe research problem is the lack of logical mathematical reasoning abilities of students. This study aimed to describe the effectiveness learning cooperative in terms of improvement of mathematical logical reasoning abilities of high school students. This form of quasi-experimental research design with pretest-posttest control group. Sample size was 38 students were taken proposive sampling of two classes of students at a private school in South Halmahera. This study has two variables, namely: cooperative learning as independent variables, and logical mathematical reasoning abilities of students as dependent variables. Instruments used for data collection is a logical mathematical reasoning ability tests. Primary data were obtained from the application of the test instrument, were analyzed using a statistical test of the One-Sample Test at significance level α = 5%. The results showed that the logical mathematical reasoning abilities of high school students through cooperative learning reaches 74.97% in both qualifying and the increases were relatively high 0.72.Keywords:        Mathematical Logical Reasoning, Mathematical Logical Reasoning Ability Students, and Cooperative Learning
