Abstract

This study aims to determine the actual situation of student with indicators of mathematical creative thinking abilities used are originality, fluency, elaboration and flexibility to determine their mathematical creative thinking skills. Creative thinking is defined as the basic abilities that must be mastered and developed  by each student with the aim of creating new things, new ways or giving new idea in generating ways to produce new ways and solve problem as alternative solutions that are different from those that already exist before. A total of 37 student of class 8 at one of the state junior high schools in Karawang regency were the research subject and qualitative descriptive as the research method. There are 4 questions about the ability to think mathematically creatively on the flat shape material as a tes instrument given to student. Data analysis in this research is data reduction, data  display, and verification.  The results of this study were the lowest score 18,75 and highest score of 93,75with an average score of  35,3. The conclusion is that students’ mathematical  creative thinking skills in junior high school students in karawang city are less creative.

Abstract

This type of research is a qualitative descriptive study that aims to analyze the mistakes of junior high school students in completing social arithmetic material. The subjects used were 20 students of class VIII-C SMP Sejahtera 2 Cileungsi, one of the private junior high schools in Bogor Regency. The data collection technique used was in the form of student test results with written questions in the form of descriptions of 5 questions, then each error faced by students was described in each question number on the social arithmetic material. The data analysis performed was data reduction, data presentation and conclusion drawing. The highest percentage of errors was in question number 4, which was 75%, while the lowest percentage of errors was in question number 2, which was 10%. Based on the results of the study, it showed that there were several mistakes in solving the essay questions, namely errors in understanding the basic concepts, errors in principle in reading the essay questions, and errors in operating the data contained in the questions. The conclusion from the results of this study obtained data that the ability of students still experienced many errors in solving social arithmetic questions.

Abstract

This study aims to determine the student difficulties in the SPLDV material. This research is a quantitative descriptive study that examines students difficulties yn the SPLDV material based on indicators (1) Modeling the SPLDV (2) Analyzing the completion of the SPLDV (3) Finding the solution to the SPLDV using Elimination and Subtitution methods (4) Summarizing the grap and (5) Linking the SPLDV in everyday life. The research was carried out in one of the private junior high school in Padalarang. The subjects of this research ere 15 students who have studied the SPLDV material. The data collection is by giving questions to student. The data analysis technique went though three stages, namely data reduction, data presentation, and conclusion. The results of the study show that there are still students who have difficulty in concluding the indicators of the graph, this can be seen from the average value of 27% which belong to the very poor category. It is also found that the factors that make the indicators on the SPLDV material esperience difficulties are the lack of accuracy when working on problems, difficulty in classifying known objects, and not mastering the concepts and principles of SPLDV.

Abstract

The purpose of this study was to determine the ability to increase understanding of mathematical concepts of SMP Negeri 4 Natar students by applying the ELPSA learning model, ELPSA learning model through dart board math media and conventional learning models. The method in this study is a quantitative method using Quasy Experimental research and the research design used is Pretest-Posttest Control Group Design. The normality test used the Liliefors method, the homogeneity test used the Bartlett method. The N-Gain test is used to see the increase in the ability to understand mathematical concepts. Hypothesis testing using the one-way ANOVA test was continued using the Scheffe test (follow-up test) using a significant level of 5% or 0.05 and it can be concluded that increasing understanding of mathematical concepts applied by the ELPSA learning model through dart board math is better than increasing understanding of mathematical concepts who were treated with the ELPSA learning model and the conventional learning model.
