Abstract

This research aimed to determine the effect of learning model on: science process skills in SMA Negeri 1 Langsa. The research applied experimental queasy method research with 3 classes which were using by cluster randome technique. Class A learnt with problem based learning model, class B with  guided discovery lerning model, while class C (control) learnt with conventional lerning model. the data analysis technique used Covariat Analysis (ANACOVA) at the level of significance α = 0,05 by using SPSS 21.0. The result showed: there was significant effect of learning models on student’s science process skill (F = 50.953; P = 0.00). student’s science process skill learnt by problem based learning (84.5 ± 5.3) significantly higher than guided discovery (75.30 ± 7.7), and conventional learning models (65.90 ± 8.1).

Abstract

This study was aimed to determine the effect of problem based learning and group investigation on: (1) learning outcomes; and (2) creative thinking ability of student in class XI of SMAN 1 Muara Batu. This type of research is a quasi-experimental research with pretest-posttest control group design. Samples were selected using random cluster sampling technique and divided into experimental and control classes. Class XI IPA3 was applied problem-based learning model,  class XI IPA1 was applied to the model group investigation, and class XI IPA2 was applied in the conventional learning (control). Multiple choices were used to measure learning outcomes, while tests of creative thinking skills in the form of essay questions. Data were analyzed using Analysis Covarian (Anacova) at significance level α = 0.05 and followed by Tukeys test with SPSS 21.0. The results showed that: (1) There was an effect of learning model to the learning outcomes of students (F = 14.183, P = 0.000). Students who were taught by problem-based learning model was significantly different from those of group investigation and conventional learning model; and (2) There was an effect of learning model to students creative thinking abilities (F = 12.030, P = 0.000). Students who were taught by problem-based learning model was not significantly different from the group investigation model but differed significantly with students who were taught by conventional learning model.
