PENGARUH PENDEKATAN CONTEXTUAL TEACHING AND LEARNING (CTL) BERBANTUAN MEDIA POWERPOINT TERHADAP PENINGKATAN HASIL BELAJAR IPA FISIKA

Abstract

Based on the interview results through some of the physics teacher in the district of Camplong, Sampang regency was taken information that the students' learning outcomes is still low below a predetermined school standard criteria. This is due to the lack of use of a medium of learning, the learning process used teacher-centered so that most students are not able to link between what they learn with how they can use it in real life. The purpose of this study was to identify the effect of the CTL-approach by powerpoint media to increase student learning outcomes physics. The method used in this research is Quasi Experiment by using a nonrandomized control group pretest-posttest design and divided into two groups: the experimental group and the control group. The research instrument used is the form of multiple choice objective test. This test consists of four options and the results are analyzed by t-test. From the calculation results obtained t value at 10.81 while t table of 2.021 at significance level of 0.05 or knowable t count > t table. Based on N-gain calculation, it can be stated that the improvement of learning outcomes on physics by using CTL approach-aided the powerpoint media is higher than in conventional learning, 0.71>0.52. Based on the results of statistical analysis and descriptive, it can be concluded that there is significant influence from the applying of CTL approach-aided powerpoint media to improve the learning outcomes of students in class VIII MTs on physics.
