Abstract

The study aims to analyze the problem solving ability of junior high school students on linear equation system of two variable. The method of this study is qualitative descriptive method. The subject of this study is 20 students IX at one state junior high school in Kabupaten  Karawang. Technique data collection using test and interviews. Technique data analysis using data reduction, data presentations and drawing conclusions. The results obtained in this study are from the 4 stages of mathematical problem solving ability, the percentages are as follows: (1) understanding the problem by 33%, (2) planning problem solving by 87%, (3) implementing a solution plan by 65%, (4) checked back by 47%. Most students with high abilities already understand the problems given, students with moderate abilities are mostly less careful in carrying out solving plans and students with low abilities mostly do not understand the problems contained in the questions.

Abstract

The study aims to determine the effect of the problem-based learning (PBL) model assisted by Google Site on the students’ mathematical concept understanding ability. This type of research uses quantitative research with an experimental method. The subject is two classes, 30 students in VIII G as the experimental class and 30 students in VIII I as the control class. The data collection technique uses a description test in the materials in flat-sided shape and interviews for observation. Technique data analysis using the t-test with SPSS version 26 and determining the magnitude of the effect using the effect size test. The result obtained that the average mathematical concept understanding ability of students who receive learning with the PBL model assisted by Google Site is better than students who receive learning with conventional learning. Thus, it can be shown that a significant effect of applying the PBL model assisted by Google Site on the mathematical concept understanding ability. The effect size on the students’ post-test is 1.85. This shows that the effect of the problem-based learning model assisted by Google Site on the students’ mathematical concept understanding ability is in the high category.
