Abstract

This study was conducted to determine the effect of buzz group discussion learning methods on the activeness and learning achievement of physics in class VIII of SMPN 4 Praya Barat Daya 2015/2016 Academic Year. The type of research used in this study is a kind of quasi-experimental research. The population in this study were all eighth-grade students totaling 38 people consisting of class VIII A totaling 20 people as the experimental class and class VIII B totaling 18 people as the control class with the sampling technique used was a saturated sampling technique. The instruments used are valid observation and test sheets both in content, construct, and empirical with a value of 3.34; 3.40; and 3.23, and reliable with the value of αCronbach = 0.608. The results of this study were also able to influence the achievement of learning physics. Based on statistical calculations using the ttest test, the value of tcount = 23.00 is greater than t table = 2.02 (t count = 23.00> t table = 2.02). Thus, it can be concluded that there is the influence of buzz group discussion learning methods on the activeness and learning achievement of physics in class VIII Praya Barat Daya SMP 4 2015/2016 Academic Year.

Abstract

Science learning carried out by teachers mostly uses conventional methods and rarely uses media in the activities of their teaching and learning process. Media mind mapping in physics learning can be used to describe a lot of material and can package it to be more interesting. The aim of this research to determine the effect of mind mapping media toward the students’ concept understanding. This study used quasi-experimental research with pretest and posttest control group design. The population used was all students of class X in SMA Negeri 1 Lingsar at 2018/2019 Academic Year. The number of samples are 32 students for the experiment class and 33 students for the control class taken by purposive sampling technique. Data analysis technique used is the t-test using IBM SPSS Statistics 22. Based on the results of hypothesis testing (t test), it is known that the significance value of the posttest data (0.00) is smaller than alpha testing (0.05), so it can be stated that the mind mapping learning method influences the students' understanding of concepts.

Abstract

The role of education is to improve the quality of education, especially in producing high-quality students. High-quality students are those who are able to think critically, creatively, logically and take initiatives in responding to issues in society caused by the impact of the development of science and technology. This study aims to determine the effect of a scientific approach to students' critical thinking skills. This study is an experimental research with one group pretest-posttest design. The sample of this study consisted of one class (28 students), which was treated using a scientific approach. Critical thinking skills are measured using a test instrument and then analyzed statistically (t test). Hypothesis test results indicate that there is an effect of using a scientific approach toward students' critical thinking skills.
