Implementation of Case Based Learning (CBL) to Improve Scientific Reasoning Skill on Simple Harmonic Vibration Topic

Abstract

This research aim to describe the increase scientific reasoning skill and the responses learners toward of implementation Case Based Learning (CBL) in SMA Negeri 1 Puncu. The type of this research is pre-experimental with one group pretest-posttest design use 1 implementation class and 2 replication class. The data analysis used analysis implementation of learning and analysis pretest-posttest use t-pair test, analyze n-gain and ANAVA. The result show that the scientific reasoning increase in SMA Negeri 1 Puncu are medium category, The replication class 1 with a value <g> of 0.6230, The replication class 2 with a value <g> of 0.6002 and The implementation class with a value <g> of 0.6020 with the result that increase in these class are consistent. Based on the results, it can be concluded that there was improvement scientific reasoning skills after implementation of Case Based Learning (CBL) on simple harmonic vibration topic.
