Abstract

This study was motivated by the results of a dialogue with one of the mathematics teachers of SMAN 7 Palu which showed that the mathematical communication of students of SMAN 7 Palu was still quite low. While the students' interest in learning mathematics has increased quite a bit. One of the aspects that must be mastered by students to achieve learning objectives is the ability of mathematical communication. The purpose of this study is to: (1) Show whether or not there is a significant positive effect of mathematical communication ability on mathematics learning achievement of class X students of SMAN 7 Palu (2) Show whether or not there is significant positive effect of learning interest on mathematics learning achievement of class X students of SMAN 7 Palu Palu (3) Show whether or not there is a significant positive effect of mathematical communication ability and learning interest on mathematics learning achievement of class X of SMAN 7 Palu. This research is a research with quantitative approach. The population this study were all class X students of SMAN 7 Palu in the school year 2023/2024 which arnounted to 357 people. The sampling technique used was simple random sampling with a sample of 36 students. Data collection was obtained through a test of mathematical communication skills in SPLDV (System of Linear Equations of Two Variables) material, a questionnaire of interest in learning and report card scores in mathematics even semester of the 2023/2024 school year. Data analysis in this study was carried out using normality test, linearity test, multicollinearity test, heteroscedasticity test and autocorrelation test. Hypothesis testing in study used simple and multiple linearregression analysis test, F tests and coefficient of determination tests. The results of data analysis show that the research data is normality distributed, each independent variable on the dependent variable is linear, there is no multicollinearity, no heteroscedasticity and no autocerrelation symptoms. The results of hypothesis testing show that at a significance level of 5% (1) There is significant effect of mathematical communication skills on mathematics learning achievement of class X stdents of SMAN 7 Palu by 25,9% (2) There is a significant influence of learning interest on mathematics learning achievement of class X students of SMAN 7 Palu by 27,1% (3) There is significant influence of mathmematical communication ablitity and learning interest on learning achievement of class X students of SMAN 7 Palu by 38,0%.

Abstract

This study aims to obtain the results of error analysis of 8th grade students of SMP Negeri 6 Palu in terms of mathematics ability with high, medium and low ability categories in solving AKM problems. The subjects of this study were 3 students of class VIII SMP Negeri 6 Palu who were selected based on the category of mathematical ability level. The type of research used was descriptive with a qualitative approach Students' errors were analyzed using Newman's procedure which includes five categories of errors: reading, comprehension, transformation, process skills and encoding. Data were obtained through AKM numeracy level 4 written test and in-depth interviews. Based on the results of the research and discussion, it can be concluded several things. namely: (1) none of the subjects made reading errors, because when asked to read the problem all subjects could read the problem properly (2) none of the subjects made comprehension errors, this can be seen during the written test and interview that all subjects can explain the important information contained in the problem and can explain what is asked in the problem (3) transformation errors were made by all research subjects, because the three subjects could not use the appropriate problem solving method. (4) process skill errors were made by all research subjects, because the three subjects were mistaken in operating the problem or incorrect in performing calculations (5) encoding errors were made by all research subjects, because the three subjects were wrong in writing the results or did not write the final result of the answer.

Abstract

This study aims to describe the application of the Team Games Tournament type cooperative learning model assisted by quizizz in improving student learning outcomes on the material of rank numbers in class VIII SMP Negeri 21 Palu. The subjects in this study were all students of class VIII SMP Negeri 21 Palu. The research instruments used consisted of observation sheets, test questions and interviews. The results showed that the Team Games Tournament type cooperative learning model assisted by quizizz could improve student learning outcomes on the material of power numbers in class VIII SMP Negeri 21 Palu, by following the steps of the Team Games Tournament type cooperative learning model, namely: (1) class presentation, (2) learning in groups, (3) games, (4) tournament, and (5) team recognition. The results of the end-of-action test showed that in cycle I it was seen that students were still difficult in solving the problems given so that there were some students who could not solve the problem and there were students who still had difficulty in determining negative power numbers. Whereas in cycle II students had a better understanding of how to work on power numbers in determining the properties of power numbers. Based on the percentage of Classical Learning Completeness (KBK) in cycle I, it shows that students have difficulty in solving negative power number problems. This can be seen from the number of students who completed, namely out of 22 students who took the final test, there were only 14 students who got a complete score or got a score that reached the KKM of 75, so the percentage in cycle I only reached 63.63%. Whereas in cycle II shows that of the 17 students who took the final test, 16 students obtained a complete score or reached the KKM which is 75, so the percentage results in cycle II reached 93.11%. In addition, the results of observations of teacher activities in managing learning and student activities in participating in learning show an increase in each cycle. Based on the data from the research results, it can be concluded that the cooperative learning model of Team Games Tournament type assisted by quizizz can improve student learning outcomes on rank number material in class VIII SMP Negeri 21 Palu.

Abstract

This study is a descriptive study with a qualitative approach that aims to describe and examine students' errors in solving linear equations of one variable (PLSV) based on Newman's stages and their causes. This data was collected through written assignments and interviews. The subjects of this study were students of class VII b at SMP Negeri 19 Palu. The informants in this study were three students of class VII b with each student having high ability, one student having medium ability, and one student having low ability at SMP Negeri 19 Palu who made the most errors. The results of this study indicate that the types of errors made by students are: (1) reading errors, (2) understanding errors, (3) transformation errors, (4) pcess skill errors, and (5) errors in writing answers. The factors causing the errors made by students are: (1) students are not careful in working on the questions. (2) students are unable to read words or recognize symbols in the questions (3) do not know the steps in solving the questions (4) students are in a hurry when solving the questions. (5) students do not understand the material being studied.
