Application of Scramble Learning Model to Improve Learning Outcomesof Chemistry Study High School Students 3 South Tambun

Abstract

Chemistry learning at SMAN 3 Tambun Selatan is still dominated by teacher-centered information delivery, sample modeling and practice questions. As a result, students are less interested and more passive in the process of learning chemistry. Based on the results of the chemistry learning process questionnaire that has been filled out by students of class X and XI of SMAN 3 Tambun Selatan FY 2018/2019 the results obtained in the statement are able to understand the chemistry obtained answer "yes" as much as 42.5%, do not feel difficulties in learning chemistry obtained "yes" answers as much as 6.3%, and able to do chemical tasks without cheating obtained "yes" answers as much as 16.8%. So, it can be said that the chemistry learning outcomes of SMAN 3 Tambun Selatan is very lacking. This study aims to determine the increase in chemistry learning outcomes of students at SMAN 3 Tambun Selatan TA 2018/2019. This study uses a pretest-posttest control group design. The study population was students of class X IPA SMAN 3 Tambun Selatan TA 2019/2020. The research sample consisted of two classes, namely class X IPA 4 as an experimental class using a scramble model and X IPA 5 as a control class without using a scramble model with a sample of 62 students. Normality and homogeneity tests use the Kholmogorov-Smirnov test and the Levene test. Hypothesis testing uses Paired sample t-test on the hypothesis of learning outcomes. There is an increase in chemistry learning outcomes. In the hypothesis test Ha learning outcomes are accepted, with the value of t arithmetic (29,133)> t table (2,000).
