EFEKTIVITAS MODEL PEMBELAJARAN THINK TALK WRITE BERBASIS SIBERNETIK TERHADAP KEMAMPUAN PEMECAHAN MASALAH MATEMATIKA SISWA - 2151500018

ABSTRAK
Tujuan eksperimen ini untuk melihat keefektifan model pembelajaran Think Talk Write berbasis sibernetik guna membantu siswa memecahkan masalah matematika. Metode yang digunakan yaitu kuantitatif dengan tipe penelitian eskperimen semu. Sampel dipilih dan terdapat dua kelas dengan kemampuan memecahkan masalah matematika yang sama berdasarkan analisis nilai awal. Analisis data melalui uji-t dengan α = 0,05. Instrumen tes telah diakui validitasnya oleh kedua validator dan berupa soal memecahkan masalah matematika disertai rubrik penilaian. Hasil tes tersebut
dilakukan uji-t sebagai uji efektivitas dan didapatkan penentuan bahwa H0 ditolak. Hal itu bermakna terdapat perbedaan rata-rata kemampuan pemecahan masalah matematika siswa dari dua kelas sampel. Berdasarkan marginal rata-ratanya, kelas yang diterapkan model pembelajaran Think Talk Write berbasis sibernetik lebih baik daripada kelas dengan pembelajaran konvensional.
Kata kunci: pemecahan masalah matematika; sibernetik; think talk write.
ABSTRACT (10pt)
The aim of this experiment is to see the effectiveness of the cybernetic-based Think Talk Write learning model to help students solve mathematical problems. The method used is quantitative with a quasi-experimental research type. The sample was selected and there were two classes with the same ability to solve mathematical problems based on initial value analysis. Data analysis via t-test with α=0.05.
The test instrument has been recognized for its validity by both validators and is in the form of questions to solve mathematical problems accompanied by an assessment rubric. The results of the test were carried out by a t-test as a test of effectiveness and it was determined that H0 was rejected.
This means that there are differences in the average mathematical problem solving abilities of students
from the two sample classes. Based on the marginal average, classes that apply the cybernetic-based Think Talk Write learning model are better than classes with conventional learning.
