PENGARUH MODEL PEMBELAJARAN KOOPERATIF TIPE STAD DENGAN PENDEKATAN PEMECAHAN MASALAH TERHADAP KEMAMPUAN BERPIKIR KRITIS MATEMATIS DITINJAU DARI PENALARAN FORMAL
Abstract
Penelitian ini bertujuan mendeskripsikan pengaruh model pembelajaran kooperatif tipe STAD dengan pendekatan pemecahan masalah dan penalaran formal terhadap kemampuan berpikir kritis matematis bagi siswa kelas X SMA Negeri 5 Denpasar tahun pelajaran 2012/2013. Desain penelitian ini menggunakan Post-test Only Control Group Design. Metode random sampling digunakan untuk menentukan kelompok eksperimen dan kontrol dari empat kelas setara di kelas X SMA Negeri 5 Denpasar yang berjumlah 84 orang. Data dianalisis secara deskriptif dan untuk pengujian hipotesis digunakan Anava Dua Jalur.
Temuan penelitian menunjukkan bahwa: (1) terdapat perbedaan kemampuan berpikir kritis matematis pada siswa yang pembelajarannya menggunakan model kooperatif tipe STAD berpendekatan pemecahan masalah dengan siswa yang pembelajarannya menggunakan model kooperatif tipe STAD. Ini dapat dilihat dari hasil analisis didapat FA hit = 82,292 dan nilai sig = 0,000 (p < 0,05), dan nilai rata-rata kemampuan berpikir kritis matematis pada siswa yang pembelajarannya menggunakan model kooperatif tipe STAD berpendekatan pemecahan masalah dengan siswa yang pembelajarannya menggunakan model kooperatif tipe STAD ( A1 = 74,14 > A2 = 62,36) dan (2) terdapat interaksi antara kemampuan berpikir kritis matematis pada siswa yang pembelajarannya menggunakan model kooperatif tipe STAD berpendekatan pemecahan masalah ditinjau dari penalaran formal. Ini dapat dilihat dari hasil analisis (FhitungAB = 5,589 dan nilai sig = 0,000, yang berarti bahwa nilai sig < 0,05). Hasil ini menunjukkan bahwa dalam mempengaruhi kemampuan berpikir kritis matematis, secara statistik model pembelajaran dan penalaran formal saling berinteraksi.

This research aimed to describe the affect of cooperative learning mode STAD type with problem solving approach and formal reasoning to the way of mathematical critical thinking students in class X in SMA Negeri 5 Denpasar in the year of 2013/2014. The design of this research used Post-test Only Control Group Design. Random Sampling had been used to defined the experiment cluster and control from four equal classes in class X in SMA Negeri 5 Denpasar which amount around 84 students. The data was analyzed using descriptive analysis and to testify the hyphoteses the researcher had used Anava with two paths.
The research’s result had been shown that : (1) there was the difference in mathematical critical thinking ability to the students that their learning was using cooperative learning STAD type mode with problem solving approach with the students that was using cooperative learning STAD type mode. This can be noticed through the analysis result which gained FA hit = 82.292 and the value of sig = 0.000 (p<0.05), and the average value for the ability of mathematical critical thinking for the students that was using the cooperative learning STAD type with problem solving approach with the students that was using the cooperative learning STAD type.
(x A1 = 74.14 > x A2 = 62.36) and (2) there was the interaction between the mathematic critical thinking ability to the students that was using cooperative learning STAD type mode with problem solving approach which was viewed from formal reasoning. This can be shown from from the analysis result (F hitung AB = 5.589 and sig value = 0.000, which signified that the sig value < 0.05). This research result has shown that in affecting the mathematic critical thinking ability, statistically the learning mode and formal reasoning is having the interaction.
