KEEFEKTIFAN PBL DITINJAU DARI KEMAMPUAN BERPIKIR KRITIS DAN KREATIF MATEMATIS, SERTA SELF-ESTEEM SISWA SMP

Abstrak

Penelitian ini bertujuan untuk mendeskripsikan: (1) keefektifan problem-based learning (PBL) ditinjau dari (a) kemampuan berpikir kritis matematis, (b) kemampuan berpikir kreatif matematis, dan

(c) self-esteem; serta (2) perbandingan keefektifan problem-based learning dan pembelajaran konven- sional ditinjau dari (a) kemampuan berpikir kritis matematis, (b) kemampuan berpikir kreatif mate- matis, dan (c) self-esteem. Penelitian ini merupakan penelitian eksperimen semu. Pengumpulan data menggunakan metode pemberian pretest dan posttest kemampuan berpikir kritis dan kreatif mate- matis, serta pemberian angket self-esteem sebelum dan sesudah perlakuan. Uji statistik yang diguna- kan adalah uji proporsi dan uji selisih antara dua proporsi. Hasil penelitian menunjukkan pada taraf signifikansi 5% dapat disimpulkan bahwa (1) problem-based learning efektif ditinjau dari kemampuan berpikir kreatif matematis, tetapi tidak efektif ditinjau dari kemampuan berpikir kritis matematis dan self-esteem; serta (2) problem-based learning lebih efektif dibandingkan pembelajaran konvensional ditinjau dari (a) kemampuan berpikir kritis matematis, (b) kemampuan berpikir kreatif matematis, dan

(c) self-esteem.

THE EFFECTIVENESS OF PBL ON MATHEMATICAL CRITICAL AND CREATIVE THINKING SKILLS, AND SELF-ESTEEM OF JUNIOR HIGH SCHOOL STUDENTS

Abstract

This study aims to describe: (1) the effectiveness of problem-based learning (PBL) on (a) mathematical critical thinking skill, (b) mathematical creative thinking skill, and (c) self-esteem; and

(2)  the comparison in the effectiveness between problem-based learning and conventional learning on

(a)  mathematical critical thinking skill, (b) mathematical creative thinking skill, and (c) self-esteem. This study was a quasi-experiment.The data were collected through a mathematical critical and creative thinking skills tests, student’s self-esteem questionnaire. The data were analyzed descriptively and statistically. The statistic tests were used test on one proportion and tests on two proportion. The results of the study that at the significance level of 5%, it can be inferred that (1) problem-based earning is effective on mathematical creative thinking skill, but it’s not effective on mathematical critical thinking skill and self-esteem; and (2) problem-based learning is more effective than conventional learning on (a) mathematical critical thinking skill, (b) mathematical creative thinking skill, and (c) self-esteem.
