Physics Problems

This research is a descriptive study with a qualitative approach, which aims to describe the ability of junior high school students to solve physics problems in various forms of problem representation. The subjects in this study were the IX grade junior high school students in six Palu city schools. Respondents for interviews in the study amounted to 4 people for each form of problem representation, with the criteria of students who answered right, students who answered ± 50% correct, students who answered incorrectly, and who did not answer. The instrument used was a test of problem solving skills and interviews. The data obtained were analyzed qualitatively including data reduction, presenting data and verification while descriptive analysis was performed by calculating the total score, calculating the percentage and categorizing problem solving abilities. The results obtained by the average ability of junior high school students to solve physics problems in various forms of problem representation 21.86% (less category), with the percentage of each form of representation ie verbal representation 36.09% (less category), image/picture representation 23.78% (less category), diagram representation 19.47% (poor category) and graphic representation 8.10% (poor category).

The rapid of education today requires empowerment skills to construct a science, one of the ways is adapting and training in a skill of problem-solving to face more advanced through learning and teaching materials. The purpose of this research is to know the difference skill of problem-solving based on learning science in junior high school in the different academic. Collecting data using rubric problem-solving skill given to students with academic distinction on April. The instrument of this research is a rubric problem-solving skill validated by the experts. The data were analysed with descriptive quantitative using Microsoft Exel. The result of data analysis of this research, there are some differences in problem-solving skills science of a junior high school of difference academic. A student who got the high score in academic tends to have better problem-solving skills.

Good Problem

Problem solving is solving problems. To develop problem-solving skills, students need to solve many problems on their own. But they also need to see good problem-solving techniques illustrated by you, the teacher. In this article, four specific problems are presented, discussed, and extended to illustrate how diverse instructional strategies, materials, and resources can be used in the junior high school classroom to develop these skills.

Problem Description

The purpose of this study was to analyze the problem solving skills of junior high school students based on student gender. This research is descriptive qualitative. Data from the research results obtained from the results of writing written questions and the results of oral interviews of 14 students of class VIII from Waringin Middle School, Bandung. The instrument used is 3 numbers of material questions that are in accordance with indicators of cognitive aspects. The results of this study indicate that from the problem description given and from the results of interviews about problem solving abilities of junior high school students with female gender on average, it is better than the problem solving ability on average junior high school students have a way to solve while solving problems. So that researchers can conduct research using active student learning methods to get better results, and also be able to understand other factors related to problem solving problems of junior high school students, both male and female students.

This study aims at producing an assessment instrument of the PISA model to measure students’ problem-solving skills and scientific literacy in junior high schools that are valid, practical, and having potential effects. This research employed the design of development studies. The analysis used the Item Response Theory (IRT) Rasch model based on the junior high school students' responses to the developed PISA assessment instrument on natural science subjects. The result of this study was a test set of PISA model for the material of Vibration, Wave, and Sound consisting of 40 items. The test was valid in terms of content, constructs, and language according to the expert assessment, and practical based on small group trials. It also had a potential effect based on the students’ answers and questionnaires results in the field test. The qualitative analysis showed that the developed test had several potential effects, i.e. the development of students' problem-solving skills and scientific literacy so that they gained a relatively high ability to solve a test with the PISA model. The results of quantitative analysis through field test trials showed that there was a significant effect from the application of the PISA model test to enhance students’ scientific literacy and problem-solving skills in the junior high school with the Sig. value of 0.000 which was less than the significance level of 0.05 (α = 5%).

This study aims at analyzing the effect of the Virtual Instrument System Laboratory (Vis-Lab) to enhance technological literacy and problem-solving skills among junior high school students. This type of research can be categorized as Quasi-experimental research with Nonequivalent Control Group Design. The subjects of this study were the seventh-grade students in one of the junior high schools in Sleman Regency, Yogyakarta. The research instrument consisted of pretest and posttest on technological literacy and problem-solving skills. The data analysis technique used N-Gain analysis, prerequisite test, hypothesis testing with MANOVA, and effect size. Based on the MANOVA test, the Sig. value of 0,000 <α (0.05) indicated that there was a gap in the students’ technological literacy and problem-solving skills between the control and the experimental class. The use of VIS-Lab learning media enhanced the ability of technological literacy by 9.0% for the experimental class and 2.1% for the control class respectively. Meanwhile, the effective contribution to the use of VIS-Lab learning media was 36.5% for the experimental class and 4.73% for the control class. It means that the use of VIS-Lab learning media contribute effectively to improving the ability of technological literacy and problem-solving.
