Abstract

This research is motivated by the emergence of barriers to student in grade VIII of SMP Negeri 2 Hiliduho in flat-sided. The purpose of this research is to design a mathematics learning module based on Discovery Learning and Obstacle Solving on the material of prisms and pyramids that is valid, practical, and effective. This type of research is design research. The design model used is the Didactical Design Research (DDR) model. The first stage is analyzing the didactical situation before learning. The second stage is the metapedidactic stage, which is learning activities to carry out individual trials, small group test, and field trials. The third stage is the retrospective stage, which is the stage of analyzing the metapedidactic stage.  Based on the research results, the designed learning module has been tested very valid by two material expert validators with an average percentage of 92.18%, language expert validator of 97.73%, and design expert validator of 98.80%. Furthermore, the module is also very practical to be use by students with a percentage of practicality of 92.23% and the percentage of practicality from the teachers of 93.18%. The module was also very effective with a percentage of classical completeness of 81.48%. From the research results above, the learning module designed based on Discovery Learning and Obstacle Solving has met expectations or objectives of the research.

Abstract

Mathematics is a subject that must be mastered by students at school. But the reality is that SMP Negeri 1 Botomuzoi students suffer from learning difficulties because of the mathematical communication skills of the students who are still in the category. So, the student is unable to communicate his ideas and ideas without the teacher's involvement. The aim of this study was to find out the influence of Trefffinger's learning model on students' mathematical communication skills. This type of research is experimental research using experimental methods (quasy experimental research). The research population was a whole of class VIII students consisting of 4 classes with samples of 2 classes taken by random sampling, namely class VIII-3 as a control class and class VIII-4 as an experimental class. The data is collected by giving the student a mathematical communication skills test that is analyzed by guiding the student's mathematics communication ability test withdrawal. Based on the results of the research, obtained the test of the hypothesis with the value thitung = 11,687 and the value ttable = 1,67. Because thitung > ttable or 11,687>1,67 then reject Ho and accept Ha. which means “There is an effect of Treffinger's learning model on the mathematical communication skills of students in SMP Negeri 1 Botomuzoi

Abstract

This research is based on a preliminary study conducted by researchers during observations at SMP Negeri 3 Mandrehe Barat. The problem is that students' mathematical problem-solving skills still need improvement. This study aims to determine whether there is an effect of brainstorming learning methods on students' mathematical problem-solving ability. This type of research uses the quasi-experimental research method involving two groups that are given different treatments. The population of this study was all VIII classes of SMP Negeri 3 Mandrehe Barat, and two classes were selected by simple random sampling as research samples, namely class VIII-A totaling 20 students as an experimental class taught using the brainstorming learning method and class VIII-B 21 students as a control class taught using conventional learning methods. Data were collected through student mathematical problem-solving ability tests. Based on this research, the results of hypothesis testing are   and . Because   > , then Ho is rejected, and Ha is accepted that there is an effect of brainstorming learning method on students' mathematical problem-solving ability at SMP Negeri 3 Mandrehe Barat.

Abstract

This study was motivated by the lack of self-confidence, fear, worry, discomfort, and nervousness of students during the mathematics learning process and the low mathematical communication skills of students. This study aims to determine the effect of self-efficacy and mathematical anxiety on students' mathematical communication skills. This type of research is correlational research with quantitative methods. The research instrumental used are self-efficacy questionnaire, mathematical anxiety questionnaire and mathematical communication ability test. The population in this study amounted to 43 people with a sample size of 39 people taken using probability sampling with simple random sampling technique. The data analysis used is multiple linear regression. Based on the results of the study, obtained in the First hypothesis the value of tcount(3.9116) >ttabel (0.0631) with H0 rejected and Ha accepted which if students' self-efficacy is higher then students' mathematical communication skills are also higher and vice versa. In the second hypothesis, the value of tcount(0.2819)>ttabel (0.0631), with H0 rejected and Ha accepted which if students' math anxiety is high then their math communication skills are low and vice versa. Concluded that the two independent variables together have a significant influence on the dependent variable with a percentage of 32.45%.
