Straight Line

This study aims to determine the level of communication skills and mathematical creative thinking of junior high school students through tests of straight-line equation questions, and analyze the difficulties of students in solving problems in the matter of straight-line equations. The population in the study were all eighth grade students of Pasundan 1 Junior High School 1 Cimahi with a sample of 9 students in class VIII I who were taken using the proportionate stratified random sampling technique that is by taking samples from each strata proportionally randomly with the provisions of each of the 3 high-ability students , 3 students with moderate ability and 3 low-ability students. The research data was collected through a test of mathematical communication skills based on the indicators of 4 essay questions. The results showed students' mathematical communication skills of 34.4% included in the less category, while for creative thinking ability was 41% including sufficient categories. Based on the answer analysis students have been able to identify elements that are known and asked and stated them in mathematical symbols, able to identify the links between elements / data that are known and asked, only students have not been able to complete mathematical models and determine relevant solutions. Based on the results of the average questionnaire shows that students' self-confidence in mathematics learning can be categorized as being. These results are directly proportional to the results of tests of low mathematical communication skills and creative thinking abilities that are categorized sufficient.

The purpose of this study was to determine the improvement of students' mathematical communication and disposition abilities taught with discovery learning models. This study us quantitative approach with the type of experimental research and the research design us pretest and posttest design type experiments. The sample was chosen randomly from two classes of 7th grade in one of public junior high school in Sigli, Aceh. The research instrument used was mathematical communication ability test and mathematical disposition questionnaire. The data analysis of students' communication and disposition ability was done by two-way ANAVA test at a significant level of 0.05. The results showed that the improvement of students' mathematical communication and disposition skills taught with discovery learning models was better than those taught with conventional approaches. Furthermore, there was no interaction between discovery learning model and the level of students towards improving communication skills and mathematical dispositions. Therefore, the mathematics teachers can implement discovery learning models in learning to build the next polyhedron. Future researchers should conduct research at other schools in order to improve students' mathematical communication skills in mathematics learning

The purpose of this study was to analyze and explore the effectiveness of constructivism approaches in improving mathematical communication skills of junior high school students in the city of Paser. The experimental quasi method was used in this study to test the hypothesis of the study. The sample of the study at three junior high schools in Paser City, representing high, medium and low school students.. The instruments used in this study were pre-post test, pre-post questionnaires, and observation. The data were analyzed using independent sample t-tests, paired sample tests, annova tests, and descriptive analysis. The findings of pre-post test and pre-post questionnaire analysis using t-test showed that there were significant differences in group mathematical communication skills using constructivism approach compared to groups using conventional approaches at all achievement levels of high school students (high, simple and low). Based on the observation, it is found that high achievement school students have good mathematical communication skills in mathematical communication, these are identified in many aspects and observation indicators achieved by students during learning.
