Abstract

This study aimed to describe the level of critical thinking skills in Year 7 students of SMPN 1 Narmada related to the subject of Algebra. This study was quantitative descriptive. The instruments of this study implemented the indicators based on Perkins and Murphy’s levels of critical thinking skills, which are (1) clarification, (2) assessment, (3) strategy, and (4) inference. There were 352 students in this study population with 64 students as the samples were obtained with a simple random sampling technique. Written test and interview was applied as the data collection technique with descriptive statistics as the data analysis technique. The results showed that 4,69% of the students grouped as having a high level of critical thinking skills had already had the ability to answer all questions completing all stages of critical thinking skills. While 4,69% of the students categorized as having the middle level had answered the questions using their level of critical thinking skill except for numbers 3 and 4 leaving some incompleted stages of critical thinking skill. Significantly, 90,62% of the students categorized as low level were not able to answer the questions with the stages of critical thinking skills. This concluded that the level of critical thinking skills on the subject of Algebra in Year 7 students of SMPN 1 Narmada is low categorized.

Abstract

This study aims to describe the types of reasoning errors made in solving number pattern problems. Based on mathematical reasoning procedures, error analysis was carried out based on student learning styles. The stages of mathematical reasoning in this study include the stages proposing conjectures, finding patterns, and drawing conclusions. The research subjects for class VIII A of SMPN 8 Mataram for the academic year 2021/2022 were selected by purposive sampling. To deepen the research results, two students were selected from each type of learning style. The instruments in this study are learning style questionnaires, number pattern tests, and interview guidelines. The data analysis technique used quantitative and qualitative data analysis techniques. From the results of the study, we obtained the percentage of mathematical reasoning errors, namely: (i) students with visual learning styles at the stage of proposing a guess made 42%, finding patterns 72%, and drawing conclusions 71%; (ii) students with auditory learning styles stage proposed 53% conjectures, finding patterns 67%, and drawing conclusions 70%; (iii) students with a kinesthetic learning style stage proposed 56% conjectures, finding patterns 67%, and drawing conclusions 70%; (iv) the causes of student errors with visual, auditory, and kinesthetic learning styles are a lack of understanding of number pattern material, a lack of thoroughness in calculations, a lack of thoroughness in understanding questions, and a lack of experience with concluding final results.

Abstract

This study aims to describe the critical thinking skills of class VIII students at SMP Negeri 1 Narmada in solving story problems based on a two-variable system of linear equations. This type of research is called descriptive qualitative. The instrument used in this study uses the stages of Perkins and Murphy's critical thinking skills, namely (1) clarification, (2) assessment, (3) inference, and (4) strategy. The subjects in this study were from class VIII.8, which consisted of 36 students, then given essay tests and interviews. The test results data were analyzed to determine the categories of students' critical thinking abilities in the high, medium, and low categories. Then interviews were conducted to examine the test results that had been obtained by students in the high, medium, and low categories. The results of this study indicate that 14% of students with high critical thinking skills have not been able to complete the strategy stage. Fifthly percent of students with moderate critical thinking skills have not been able to complete the inference and strategy stages. Thirty-six percent of students with low critical thinking skills have not been able to complete all stages. This shows that students' critical thinking skills in solving story problems on the material of a two-variable linear equation system are in the medium category.

Abstract

This study aims to determine the effect of the WhatsApp-assisted realistic mathematics learning model (PMR) on the mathematics learning outcomes of seventh grade students of SMPN 13 Mataram in the 2021/2022 academic year. This type of research is a quasi-experimental study with Posttest Only Control Group Design which is a form of research method. Experiment. The population in this study were seventh grade students of SMPN 13 Mataram, the sample technique used was cluster random sampling. The samples of this study were students of class VII (I) as the experiment class and class VII (J) as the control class with a total of 33 students. The instruments used are lesson plans and student learning outcomes test sheets (posttest) on the set material. The data analysis used was the t test to see differences in learning outcomes, and the effect size test to see how much influence the realistic mathematics learning model (PMR) had on students' mathematics learning outcomes. Based on the results of the posttest data analysis using the t-test, it was found that t_count = 2.1457 > t_table = 1.1998 with a significant level of 5%, so H_0 was rejected and the effect size test was d = 0.5408 (medium). So it can be concluded that learning using the realistic mathematics learning model (PMR) assisted by WhatsApp has a significant effect on the mathematics learning outcomes of seventh grade students of SMPN 13 Mataram in the 2021/2022 academic year.

Abstract

This study aims to determine the effect of problem-based learning models on social arithmetic material on the achievement of mathematics learning for grade VII students of SMP Negeri 2 Lingsar for the 2021/2022 school year. This Quasi-Experimental Design research is designed by The Posttest Only Control Group Design. The population is all grade VII students of SMPN 2 Lingsar, as many as 278 students. Sample determination is carried out by the Cluster Random Sampling technique. Class VII.5 used a problem-based learning model with 31 students as an experimental class, and Class VII.9 used a direct learning model with 30 students as a control class. The data on the achievement of learning mathematics is obtained through the final test. The assumption tests in this study are the normality test and the homogeneity test. Data analysis in this study used descriptive statistical analysis and a t-test. The results showed that the average learning achievement of the experiment class was 79,10 greater than the average learning achievement of the control class, which was 70,23. In this study, the problem-based learning model had a moderate influence on 79% of the expectations of mathematics learning achievement of grade VII students
