The effectiveness of science experiment through multimedia teaching materials to improve students' critical thinking

Abstract

The aims of this study is to explore the effects of three different forms multimedia teaching to critical thinking skills of students in the context of the science laboratory. The three forms of multimedia teaching materials are static images, videos, and animations, that used to teach science trial for 120 students from Elementary School teacher education university of Samudra, Langsa. The method used in this study is a quasi-experiment with pretest to posttest control group design. The pretest method was given to college students to determine their learning achievement before given the application multimedia to experiment science during learning process for the experimental group and also the implementation multimedia and learning feedback from a list of several questions. Descriptive statistics and ANOVA were also given to analyze data that have been collected. This study shows that videos and animations have bigger effects in critical thinking skills in the context of science laboratories rather than static images and observation performance. In addition, animation video in presentation can help students to understand the experiment and learning science easily.
