MODEL PROBLEM BASED INSTRUCTION DENGAN METODE DEMONSTRASI DALAM PEMBELAJARAN FISIKA DI SMA

Abstract

This study is aimed to comprehend the difference of the learning outcomes of students during using problem based instruction model with the demonstration method with conventional learning and to describe critical thinking skills of students with problem based instruction model with demonstration methods in learning physics in senior high. This type of research is experimental. The population in this study is a class X student of MAN 2 Jember. The research instrument is the cognitive aspects of products to measure student learning outcomes, analytical test to measure critical thinking skills of students and observers to measure cognitive of processes and affective during learning activities using problem based instruction model with the demonstration method. Data were analyzed using t - test using manual calculations. Based on the results of the study , got value students t_test = 1,82. Further value t_test  is consulted by the value t_table got of value db = 70 with significance level of 5% is 1,66. So,  can be detailed that the t_test value> t_tabel (1,82 > 1,66), thus H₀ (null hyphothesis) is rejected and H₁ (alternative hyphothesis) is accepted and the critical thinking skills of students in the learning activities using problem based instruction model with demonstration method that is equal to 70.22 % thus classified as good. The conclusion of this study are: 1) problem based instruction model with demonstration methods is better than conventional learning; 2) critical thinking skills of students with problem based instruction model with demonstration methods classified as good.
