Abstract

This study aims to determine the effect of problem-based learning models assisted by pocket book physics on problem-solving abilities. The type of research used was quasi-experimental design with pretest-posttest control group design. The population in this study were all students of class X MIPA Senior High School in Mataram. The research sample was taken using cluster random sampling technique, so that the selected students of class X MIPA five were 31 people as the experimental class and the X class MIPA six as many as 27 people as the control class. The experimental class was treated in the form of a problem-based learning model assisted by pocket book physics mobile and the control class was treated in the form of conventional learning. The instrument used to measure problem solving ability is a test instrument in the form of a descriptive test of five items. The research hypothesis was tested using the t-test with a significance level of 5%. The t-test produces a t-count value of problem solving ability of 5.832 which is smaller than  which is equal to 2.003 so that H0 is rejected and Ha is accepted. So it can be concluded that there is the influence of the problem-based learning model assisted by pocket book physics on students' problem solving abilities. This result can be proven by the N-gain test, where there is an increase in problem solving abilities of 60% for the experimental class and the control class by 34% with the medium category.

Abstract

This study aims to examine the effect of the guided inquiry learning model assisted by contextual videos on the mastery of the physics concepts of students. This type of research is a quasi-experimental design with untreated control group design with pretest-posttest. The population in this study were all students of class X MIA SMAN 3 Mataram. Sampling uses a purposive sampling technique, so students selected class X MIA 3 as the control class and class X MIA 2 as the experimental class. The type of test used for concept mastery consists of 30 multiple choice questions. The average value of posttest mastery of concepts in the experimental class and control class is 73.20 and 66.18. The statistical analysis used for hypothesis testing in this study was the t-test with a significance level of 5%. Hypothesis test results show the value of t arithmetic 2.52 is greater than the value of t table that is 2.00 so that H0 is rejected and Ha is accepted it can be concluded that there is an effect of the guided inquiry learning model assisted by contextual videos on the mastery of the physics concepts of students.

Abstract

This research is aimed to determine the effect of guided-inquiry learning model using PhET simulation on creativity at SMAN 1 Tanjung of academic year 2019/2020. This research is quasi-experimental with non-equivalent control group design. The population of this research is all student of grade XI SMAN 1 Tanjung of academic year 2019/2020, while the sampling technique used purposive sampling, while the sampling are the student of grade XI MIPA 2 as the experimental group and the student of grade XI MIPA 1 as control group. Creativity data be measured on creativity test which the type test used 7 essay. The research hypothesis was tested using t-test independent. The result of t-test show that tobtained>ttable. It means that there is the effect of guided-inquiry learning model using PhET simulation on creativity at SMAN 1 Tanjung of academic year 2019/2020.

Abstract

Problem-solving is a high-level ability to find solution to a problem. In the problem-solving process, students have to identify and understand the problems, plan the solutions, execute the plans and review the resolution process. This ability is needed by students to produce meaningful knowledge. This article discusses the effect of virtual labs in physics learning toward student’s problem-solving abilities. The improvement of problem-solving skills was analyzed in each step of the solution process. This quasi-experimental study was conducted at three different senior high schools. There were 165 students participating in this study, all of whom were divided into three experimental groups and three control groups. The research instrument used was five to eight questions of essay test. The results showed that the problem-solving ability of the experimental group was higher than that of the control group at each school. The analysis of each problem-solving step showed that, in each school, the students' ability to identify and define the problem and also to establish goals and objectives show a similar result. Students have an excellent ability in identifying problem up to plan for problem-solving, whereas for the step of analyzing the choice of ideas and step to follow up of problem-solving overall still need to be improved. Students who are unable to complete a particular problem-solving step will not be able to complete the next step well.
