Abstract

Penelitian ini bertujuan: (1) mendeskripsikan keefektifan pendekatan problem posing dalam setting pembelajaran kooperatif tipe TAI dan pendekatan konvensional ditinjau dari kemampuan komunikasi dan pemecahan masalah matematis, (2) membandingkan keefektifan pendekatan problem posing dalam setting pembelajaran kooperatif tipe TAI dan pendekatan konvensional ditinjau dari kemampuan komunikasi dan pemecahan masalah matematis. Populasi dalam penelitian ini adalah siswa kelas VIII SMP Negeri 11 Purworejo yang berjumlah 190 orang dan tersebar dalam 6 kelas. Berdasarkan pengambilan sampel diperoleh kelas VIII F sebagai kelompok eksperimen dan kelas VIII E sebagai kelompok kontrol. Data dianalisis menggunakan one-sample t-test, uji MANOVA dengan rumus T2 Hotteling dan uji-t dengan kriteria Bonferroni. Hasil penelitian adalah sebagai berikut. (1) Pada taraf kepercayaan 95%, penerapan pendekatan problem posing dalam setting pembelajaran kooperatif tipe TAI efektif, sedangkan pendekatan konvensional tidak efektif ditinjau dari kemampuan komunikasi dan pemecahan masalah matematis. (2) Penerapan pendekatan problem posing dalam setting pembelajaran kooperatif tipe TAI lebih efektif dibandingkan dengan penerapan pendekatan konvensional.

Kata Kunci: problem posing, pembelajaran kooperatif tipe TAI, komunikasi matematis, pemecahan masalah matematis.

The Cooperative of the TAI Type-Set Problem posing in Terms of the Communication and Problem Solving Competencies

Abstract

This study aims to: (1) describe the effectiveness of the cooperative learning of the TAI type-set problem posing approach and the conventional approach in terms of the mathematical communication and problem solving competencies, (2) compare the effectiveness of the two approaches in terms of their mathematical communication and problem solving competencies. The research population comprised the 190 Grade VIII students, distributed in six classes, of SMP Negeri 11 Purworejo. The selected sample consisted of Class VIII F as the experimental group and Class VIII E as the control group. The data were analyzed using one-sample t-test, MANOVA test with T2 Hotteling's formula and t-test with Bonferroni criterion. The results of the study are as follows. (1) At the 95% level of signi-ficance, the mathematics teaching through the cooperative learning of the TAI type-set problem posing approach is effective and the conventional approach is not effective in terms of the mathematical communication and problem solving competencies. (2) The application of the cooperative learning of the TAI type-set problem posing approach is more effective than that of the conventional approach.
