IMPROVING CRITICAL THINKING SKILL AND SCIENTIFIC BEHAVIOR THROUGH THE IMPLEMENTATION OF PREDICT OBSERVE EXPLAIN LEARNING MODEL

Abstract

Critical thinking skills and scientific behaviors are important abilities that must be mastered and possessed by students in solving problems. The problem which frequently faced by students is they have been able to comprehend the science but have not been able to provide conclusions logically and systematically. The phenomenon shows the low critical thinking skills and scientific behaviors of students. To overcome these problems, it needs a change in the process of delivering learning material to students. This research aims to answer the question of whether learning through the implementation of the predict observe explain model has an effect on improving student critical thinking skills and scientific behaviors. The method used in this research is an experimental design pretest posttest control group. The parameters measured were critical thinking skills and scientific behaviors. Improvement of critical thinking skills and scientific behaviors was measured by calculating gain normalization (n-gain). The instruments used were the observation sheet and objective tests with five alternative answers. Data collection is done through pretest, posttest and observation during the learning process. Analysis of critical thinking skills was done by comparing the initial ability with the final ability of students and tested the significance of the two different tests on average using independent simple t-test. The results of the study indicated that the initial ability of thinking skills between the experimental and control classes did not have a significant difference, while the final ability showed significantly different results. Based on these results, it can be concluded that the implementation of the the predict observe explain model contribute in student critical thinking skills and scientific attitudes.
