Abstract

This study aims to determine the profile of students' problem-solving skills and the implementation of free inquiry models in high school. This type of research conducted using preliminary research methods with data collection techniques in the form of written tests filled out by students, student interview questionnaires, and teacher interview questionnaires. The data obtained were analyzed descriptively qualitatively. The study was conducted on 30 students of class XII Science 5 of Senior High School 1 Driyorejo. The results showed that only a few students used the strategy of problem-solving skills in solving Dynamic Electric problems. Of all students studied, 16 students had moderate category problem-solving skills ranging from 1.00-1.99, and 14 students had low category problem-solving skills with a range of 0.00-0.99. The lowest problem-solving skills criteria are at point C (conceptualize the strategy). So it can be concluded that the implementation of a free inquiry learning model assisted by virtual laboratories (PhET) in schools does not optimally cause students to be inactive in class so that the problem-solving skills of students are not in the high category.

Abstract

This study aims to determine and analyze students' understanding of the motion concept taught with video-based learning assisted by Tracker Software. The subjects of this descriptive qualitative research were 30 students from 10th grade at SMA Negeri 5 Palu. The instruments in this study were multiple-choice tests and interviewed guide. Multiple-choice tests are used with reasons and are equipped with a Specific Response Index (CRI). It was given before and after video-based learning assisted by Tracker Software applied. To add the information about students' understanding, the interview with a few respondents was done. Respondents were selected based on subjects' written test results in the high, medium, and low categories. They also were interviewed related to their conception and certainty of their answers. In learning by using video-assisted by tracker software, the student also employed the worksheet in experimenting. The results showed that a conceptual understanding of student motion on the initial test could be categorized as low. After using video media that is assisted by Tracker Software, students' conceptual understanding increases. Thus, the teacher can use video media and software to teach physics concepts that can be directly observed and displayed using mathematical and graphical representations.

Abstract

The research aims to obtain information on the ability to understand the physics formulas of high school students being taught through direct learning models. The population subjects in this study were 360 high school students. The research sample was taken using a random class technique, with a total sample of 79 students. This research used instruments in the form of tests of understanding students' physics formulas in the form of essays that have been tested before being used in research to determine the validity and reliability of the tests. The normality test is performing on the experimental class which obtained Xcount2  <  Xtable2 (1,68 < 9,49) and the control class Xcount2  <  Xtable2 (1,47 < 9,49), the normality of the two data groups is normal. Homogeneity testing of variance used F-test get value 1,15, which Ftable = 1.74 (Fcount < Ftable), the variance of the two data groups is homogeneous. Data processing uses inferential analysis techniques with the "t" test. There is two class, which one class as an experimental class that was treated in the form of direct teaching-learning models and another class as a control class taught conventionally. The results there is an increase in the score of students' understanding of physics formulas taught through direct learning models. It can happen because students are invited to get accustomed to gaining procedural knowledge also can capture and interpret physics formulas that are taught through modeling or experiment.
