THE COMPARATION STUDY OF LABORATORY EXPERIMENT AND udCOMPUTER SIMULATION METHODS IN INCREASING STUDENTS’ udCOGNITIVE ACHIEVEMENT AND SCIENCE PROCESS SKILLS ON THE udTOPIC OF LINEAR MOTION

摘要

This research aims to compare the effectiveness of laboratory experiment and computer udsimulation methods in the teaching-learning of physics. It can done by testting the difference of cognitiveudachievement and science process skills for students who learn physics, on the topic of linear motion, by udusing laboratory experiment and computer simulation methods. This topic includes motions along a udstraight line with a constant velocity and a constant acceleration. udThe research method was a quasi-experiment with pretest-posttest experimental group design. It udwas conducted in SMAN 2 Wates. The population was all students in this school and the sample was the udX-grade students. The sampling technique was the cluster random sampling. After drawing lots, the X-Agrade student was the experiment group using simulation and the X-C-grade student was the experiment udgroup using experiment laboratory. Data were collected by using pretest and posttest, based on students’ udcognitive achievement and science process skills. Data analysis method to test hypothesis was Manova ud(Multivariate Analysis of Variance). Before hypothesis testing, the pre-requisite analysis was done, that is udthe normality of data distribution and variance homogeneity.udThis research shows that (1) there were the increasing differences of cognitive achievement and udscience process skills between students who learn physics on the topic of linear motion by using udlaboratory experiment and computer simulation methods; (2) the laboratory experiment method was more udeffective than the computer simulation.
