One alternative model of learning that is expected to improve problem-solving skills is the Problem Based Learning model. This research aims to examine the problem-solving abilities of junior high school students. This study is classified as Quasi Experiments that was conducted at SMP Nurul Huda in Karawang. This research was an experimental design with 80 seventh grade student as a sample, it is divided into two different classes as a Problem Based Learning class and conventional learning class. The two classes were given pretest and posttest to determine students' problem-solving abilities. The results showed that problem solving abilities students who obtained learning with Problem Based Learning were better than students who received conventional learning. The success of students in learning mathematics with Problem Based Learning and problem-solving problems shows good results.   Salah satu alternatif model dan pendekatan pembelajaran yang diperkirakan dapat meningkatkan kemampuan tersebut adalah model Pembelajaran Berbasis Masalah. Penelitian ini bertujuan untuk menelaah kemampuan pemecahan masalah dan minat belajar siswa SMP. Penelitian ini termasuk Kuasi Eksperimen yang dilakukan pada salah satu SMP di kota Karawang, Penelitian ini adalah suatu eksperimen berdisain  dengan sampel 80 siswa kelas VII pada dua kelas yang berbeda sebagai kelas Pembelajaran Berbasis Masalah dan kelas pembelajaran konvensional. Kedua kelas yang diteliti diberikan pretes dan postes untuk mengetahui kemampuan pemecahan masalah dan minat belajar siswa.  Hasil penelitian menunjukan bahwa kemampuan  pemecahan masalah dan minat belajar siswa yang memperoleh pembelajaran dengan Pembelajaran Berbasis Masalah lebih baik dari pada siswa yang memperoleh pembelajaran konvensional. Keberhasilan siswa terhadap pelajaran matematika dengan Pembelajaran Berbasis Masalah serta terhadap soal-soal pemecahan masalah menunjukkan hasil yang baik.

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).

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 article is derived from the research result entitled “The Application of Problem Solving Approach in Improving Junior High School Students’ Mathematical Communication and Disposition Skill”. The research is purposed to see and analyze if there are some improvements in mathematical communication and disposition skill achievement of the students who have been treated using problem solving approach compared to the students who are still treated using conventional approach. The population of the research is all students at a junior high school in Subang regency. Out of these students,  40 students of class VIII D were chosen randomly as the experiment class, and 41 students of class VIII C have also been randomly chosen as the control class. The data in this research have then been analyzed using parametric and non-parametric statistic. The result of this analysis has shown that the achievement of experiment class students’ mathematical communication and disposition skill is better than the achievement of the control class students. The experiment class students’ mathematical disposition is also better than those of the control class. Lastly, the result also shows that there is some kind of correlation between the mathematical communication and mathematical disposition on the level of medium.

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.
