Authentic assessment of the ability to critical thinking mathematics of junior high school students in grade VIII on statistics materials

2024-09-08T09:32:53+07:00

Mathematical critical thinking is essential for students in the twenty-first century. People become more adaptive, open-minded, and better able to react to a range of events and problems as their critical thinking skills grow. The ability for children to think critically is still quite limited. The lack of instruction that fosters mathematical critical thinking skills is to blame for this. After giving students a mathematical critical thinking stimulus while they were studying, this study aims to assess students' capacity to use critical math thinking on statistical content. The research technique used is called qualitative descriptive research. Data collection techniques include test-and-nontest approaches. Analysis of critical thinking skills is done by looking at assessment, assumption analysis, and argument analysis. Students from SMP Negeri 9 Yogyakarta in grade VIII made up the research sample. This research produces three categories of students' critical thinking abilities, namely: 1) high category students are able to analyze assumptions, analyze arguments, and evaluate; 2) medium category students are able to analyze arguments and evaluate, but are still not capable enough to analyze assumptions; and 3) low category students are not yet able to analyze assumptions, analyze arguments, and evaluate.

A Meta analysis: Does PBL influence junior high school students' mathematics abilities?

2024-09-08T09:40:25+07:00

This research aims to measure the mathematics abilities of junior high school students using the Problem Based Learning (PBL) learning model. The research method used is descriptive quantitative using meta analysis. The research mapped was obtained from journal articles, theses, theses and dissertations published between 2010 and 2020 with the help of publish or perish software as an article collection application. The research article meta-analysis technique uses the JASP 0.14.1.0 application to further interpret the heterogeneity, aggregate, bias detection, forrest and funnel plot tests. The results of the research show that the mathematics ability of Indonesian junior high school students is 74 on a scale of 0 -100. This aggregate was obtained from heterogeneous previous research results with a high category deviation index which is possible for bias. Strengthening bias was also obtained from the Rank correlation test and Regression test for Funnel plot asymmetry ("Egger's test") which showed that the p-value <0.05 and funnel plot results which did not show that the data represented a range of mathematical ability scores. This means that data from previous research shows that Problem Based Learning is indicated to have biased data that cannot generalize the effectiveness/ineffectiveness of this learning method. Researchers should publish the results of this PBL research even if the results obtained are not as expected.

2024-09-08T09:43:53+07:00

The mathematical generalization ability of students at one junior high school, especially in Makassar, is relatively low. One alternative to improve students' mathematical generalization abilities is to apply active, collaborative and inductive cooperative learning models. This research aims to determine the difference in the average score of mathematical generalization abilities of students taught through active, collaborative and inductive cooperative learning models, and students taught through cooperative learning models on flat-sided geometric material. This research used a quasi-experimental design with a pretest-posttest control group design in class VIII at a junior high school in Makassar, Indonesia. The sample in this study was 35 students in the control group and 31 students in the experimental group. The instrument used is a mathematical generalization ability test. Data were analyzed using the n gain test. Based on the analysis, the average n-gain score for students' mathematical generalization abilities in flat-sided geometric material after being taught by applying active, collaborative and inductive cooperative learning models was 0,51 or experienced a moderate increase and the percentage of learning completeness was 93,55%. Therefore, it can be concluded that junior high school students' mathematical generalization abilities increased after being taught using active, collaborative and inductive cooperative learning models.

2024-09-08T09:45:44+07:00

The aim of the research is to summarize the experiences of grade 11 students at SMA Negeri 4 Palu based on Newman's theory. This type of research is descriptive, using a qualitative approach. The research subjects were two students selected from 35 class XI students. The findings of this research are as follows: (1) Not a single subject experienced errors in reading the lesson material, because at that time every subject was considered able to read the lesson material correctly. (2) Not a single subject made a mistake in understanding, as seen in the interview phase. All research subjects were able to provide understandable and questionable information regarding the subject. (3) Each research subject carries out transformation error correction. This transformation error is characterized by the failure of a subset that reduces the problem of the mathematical model. (4) Process skills errors were made by each research subject. This is explained by the subject's understanding of the steps taken in answering the question, but most of it is caused by the subject's errors occurring in the transformation step and the subject being unable to solve mathematical problems accurately. (5) an error in writing the final answer (encoding error) was made by each research subject; This is differentiated by the fact that there are subjects who do not determine the final results of their learning and there are also subjects who fail to determine the final results due to errors in the previous stage.
