Abstract

This Research aims to know about the reasoning ability and mathematic representation ability to the results of mathematic lesson in students grade VIII SMP Negeri 1 Batulayar year academic 2019/2020. This research used quantitative approach with ex post facto research type. The population of this research is the eighth grade students of SMP Negeri 1 Batulayar. In determining the sample, probability sampling technique with the type of cluster sampling was used. The sample in this research is the students of class VIII B SMP Negeri 1 Batulayar amounted to 22 students. Data analysis used was multiple linear regression analysis. From the result of the data analysis we found the significant influence between reasoning ability and representative mathematic’s ability to the mathematics learning result of mathematic lesson in students grade viii smp negeri 1 batulayar year academic 2019/2020 with Fcount = 78,812 > F(2,19) = 3,52. The data we wroute as the same regration that Ŷ=-2,452+0,466X1+0,575X2. The equation show us that reasoning ability and the representative mathematic’s ability increase 1 unit and the learning result will increase to 0,466 from reasoning mathematics ability plus 0,575 representative mathematic’s ability.

Abstract

This study aims to determine the effect of learning motivation and parental attention on mathematics learning achievement of grade VIII students at SMPK Tunas Daud Mataram 2020/2021. This type of research is ex-post facto. The sample class was selected using a saturated sampling technique, obtained 34 students consisting of 2 classes. Data retrieval in this study was carried out by providing a questionnaire on learning motivation and parental attention and a number pattern test. Analysis of SPSS 21 program data, consisting of prerequisite tests and hypothesis testing. The prerequisite test on the data analysis used, namely the normality test of the results obtained on learning motivation, namely 0.245 and parental attention, namely 0.162 so that it is said that the data is normally distributed, the linearity test of the results obtained on learning motivation is 0.958 and parents' attention is 0.597 so that The data has a relationship with learning achievement and the multicollinearity test of the results obtained is 1.340, namely there is no relationship between independent variables. The contribution of learning motivation to mathematics learning achievement was 19.6% and parents' attention to mathematics learning achievement was 19.2%. The existence of a positive relationship between learning motivation and learning achievement and parents' attention to learning achievement is indicated by a positive correlation coefficient. A positive coefficient value indicates that the higher the motivation to learn and the attention of parents, the higher the student's learning achievement.

Abstract

This study aims to determine the influence of the cooperative learning model CORE type on the mathematical communication skills at the eight grade students of SMPN 2 Kediri in Academic Year 2019/2020 on cube and block material. The method used in this study was a quasi-experimental research design with post-test only control group design. The population of this study were all eight grade students of SMPN 2 Kediri in academic year 2019/2020, which were distributed in three classes. The sample class was selected using cluster random sampling technique, obtained class VIII-B as the experimental class and class VIII-C as the control class. As for data collection techniques, namely observation and tests. The data analysis technique used the prerequisite test, namely the normality test and the homogeneity test followed by the pooled variance t-test. Based on the results of data analysis, it was found that there was a difference between the mathematical communication skills of students who obtained the cooperative learning model CORE type and those who used the direct learning model. Classes that using the CORE model get an average score of 77.86 while those taught with the direct learning model get an average score of 65.15. This shows that learning using the cooperative model type CORE has an influence on the mathematical communication skills of students of class VIII SMPN 2 Kediri in academic year.

Abstract

The aim of this study is to describe the problem-solving ability of the ninth grade students with high, medium, and low interest in learning mathematics on math problems type Higher Order Thinking Skill (HOTS) in SMPN 2 MATARAM 2020/2021. This type of research is descriptive qualitative and the instruments used are mathematics questionnaire, the HOTS test, and an interview. The results of questionnaire via google form, there were 35 students of ninth grade has learning interest of high, medium, and low respectively 15, 16, and 4 students. Then, with stratified random sampling, 2 students were selected at each level to work on HOST test and interviews. The results of the data analysis from the ninth grade students of SMPN 2 Mataram 2020/2021 are the students with high interest in learning mathematics had very good at understanding problems, compiling plans, implementing plans, and reviewing. Students with moderate interest in learning mathematics are very good at understanding problems, good at planning, but quiet enough for implementing plans and reviewing. Meanwhile, students with low interest in learning mathematics are very good at understanding problems, good at planning, but lacking in implementing plans and very less in the reviewing them

Abstract

The aim of this study was to describe the differences of students' problem-solving abilities in completing mathematics problem in the form of story-based problems in terms of gender difference. The type of research used is qualitative and quantitative descriptive research using research instruments, namely tests of problem-solving abilities and interview. Selection of subjects using a random cluster random technique, based on teacher considerations. The subjects in this study were 26 students of class IX of SMPN 8 Mataram in the academic year of 2020/2021. The data collection method started from making observations at school, then distributing the problem-solving ability test which contains 2 problems in the form of elaborative questions. AT the last stage, the researcher conducted interviews with 6 people who were obtained from each representative of the criteria for the test results of the problem-solving abilities that had been given. The data analysis technique in this study was conducted by looking at the test scores of mathematics problem-solving abilities seen from the criteria of high, moderate, and low. The results obtained were: (1) the ability of female students in grade IX at SMPN 8 Mataram to solve mathematics problems related to the statistical topic in form of story-based problems was in moderate criteria with the average score obtained was 73.44, (2) the ability of male students in grade IX at SMPN 8 Mataram to solve mathematics problems related to the statistical topic in form of story-based problems was in moderate criteria with the average score obtained was 77,64, and (3) the difference in problem-solving abilities of male and female students lies on the steps used in solving mathematics problems based on Polya problem solving stages.
