Abstract

Penelitian ini dilakukan dengan tujuan untuk mengetahui pengaruh dari model pembelajaran kooperatif tipe Student Teams Achievement Division (STAD) dengan berbantuan LKPD terstruktur terhadap kemampuan representasi matematis siswa. Metode yang digunakan pada penelitian ini adalah penelitian Quasi-Experiment atau eksperimen semu dengan post-test only control group design. Teknik pengambilan sampel menggunakan teknik cluster random sampling. Sampel penelitian yaitu siswa kelas VIII-A dan kelas VIII-C di SMP Negeri 2 Jakarta. Kemampuan representasi matematis siswa diukur menggunakan instrumen penelitian yaitu empat soal uraian pada pokok bahasan bangun ruang sisi datar yang telah valid dan reliabel. Hasil pengujian hipotesis menggunakan uji-t’ dengan taraf signifikansi alpha = 0,05 diperoleh hasil bahwa uji t’ = 2,6 lebih besar atau sama dengan t tabel = 0,367 sehingga H0 ditolak yang berarti bahwa rata-rata kemampuan representasi matematis siswa yang menerapkan model pembelajaran kooperatif tipe STAD berbentuan LKPD terstruktur lebih tinggi dibandingkan peserta didik yang menerapkan model pembelajaran konvensional tipe ceramah. Kemudian diperoleh nilai Cohen’s d sebesar 0,641 dengan persentase besar pengaruhnya sebesar 73% yang termasuk ke dalam kategori medium (sedang). Berdasarkan hasil perhitungan, dapat disimpulkan terdapat pengaruh dari penerapan model pembelajaran kooperatif tipe Student Teams Achievement Division (STAD) berbantuan LKPD Terstruktur terhadap kemampuan representasi matematis siswa SMPN 2 Jakarta. ***** This study was conducted with the aim to determine the effect of the Student Teams Achievement Division (STAD) cooperative learning model with the help of structured LKPD on students' mathematical representation abilities. The method used in this study is Quasi-Experiment with post-test only control group design. The sampling technique used cluster random sampling techniques. The research samples were students of class VIII-A and class VIII-C at SMP Negeri 2 Jakarta. Students' mathematical representation ability was measured using research instrumens with four description questions on the subject of polyhedron that have been valid and reliable. The results of hypothesis testing using the t’- test with a significance level of alpha = 0.05 obtained that the t’-test = 2,6 more than or equal to t-table = 0,367, so that H0 is rejected which means that the average mathematical representation ability of students with STAD-type cooperative learning model with structured LKPD is higher than students with the conventional lecture-type learning model. Then the Cohen's d value is 0.641 with a large percentage of influence of 73% which is included in the medium category. Based on the calculation results, it can be concluded that there is an effect from the application of the Student Teams Achievement Division (STAD)-type cooperative learning model assisted by structured LKPD on the mathematical representation abilities of SMPN 2 Jakarta students.
