Abstract

This study aims to Getting a description of errors and factors that cause errors in doing UAS for grade VIII students of SMPN 2 Galang, knowing the teachings of 2023-2024. This research is a descriptiveresearch with a qualitative approach. The subject of this study is to take 12 students of grade VIII SMP N 2 GALANG based on the value of UAS results under the KKM and teacher recommendations that can represent the answers of other students' mistakes. The researcher selects the subject by looking at the results of the student's final semester exam. Values that are below the MMC (minimum completeness criteria) will be analyzed for errors. The standard of KKM scores set at school is 75, so that students' UAS scores that are less than 75 are analyzed for errors. The results of this study show the types of mistakes made by grade VIII students of SMP N 2 Galang based on Newman's procedure: (1) errors in understanding. (2) errors in transforming, (3) errors in process skills, and (4) errors in writing the final answer. Factors that cause errors: (1) lack of students' understanding of the material that has been taught. (2) mastery of basic mathematical skills in the form of weak mathematical computing. (3) lack of understanding of concepts that make students easily forget the material that has been learned. (4) the learning model is not optimal, so that students still have difficulties in learning mathematics and tend to consider mathematics as a difficult and confusing subject.

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

The purpose of this study is to obtain an analytical description of students' critical thinking skills in solving trigonometry problems based on personality type. This research is a qualitative study with a descriptive approach. The results of this study are as follows: Student MHA with a guardian personality type met 1 critical thinking indicator on question number 1, which is focus, and met 6 critical thinking indicators on question number 2, namely focus, reason, inference, situation, clarity, and overview (FRISCO). Student MHA with a guardian personality type tended to be thorough in completing the given problems. Student AI with a rational personality type met 6 critical thinking indicators, namely focus, reason, inference, situation, clarity, and overview (FRISCO). Student AI with a rational personality type was good at analyzing and tended to ignore things deemed unnecessary or time-consuming. Student FA with an artisan personality type did not complete question number 1. Student FA with an artisan personality type met 3 critical thinking indicators, namely focus, reason, and inference on question number 2. Student FA with an artisan personality type tended to be slow in learning/understanding mathematical material, proven by the fact that student FA with an artisan personality type could not complete question number 1 and tended to rush in working on the problem. Student AL with an idealist personality type met 4 critical thinking indicators, namely focus, reason, inference, and situation. Student AL with an idealist personality type elaborated their answers in detail, both orally and in writing.

Abstract

This study aims to describe the errors of grade VIII students at SMP Negeri Satap 1 Tinombo Selatan in solving story problems involving two-variable linear equation systems using the Newman method. Newman’s method identifies five types of errors: reading, understanding, transformation, process skills, and coding. This research employs a descriptive qualitative approach. The subjects include three students with different mathematical abilities: one high-achieving student (A), one medium-achieving student (T), and one low-achieving student (S). Data collection techniques involve written tests and interviews, with data credibility ensured through member checking. The data analysis process includes data condensation, data presentation, and conclusion drawing. The results indicate that none of the subjects experienced reading errors. However, all three made mistakes in understanding the problems. Subject T did not write what was asked in problem one and misidentified the question in problem two. Subject S also failed to state what was asked in problem two. All subjects struggled with transformation errors, mainly due to incorrect variable assignments. Subjects A and S made errors in problem two, while subject T also struggled with proper notation. Regarding process skills, subject A could not complete the division operation, subject T failed in algebraic manipulation in problem one and miscalculated multiplication in problem two, and subject S did not proceed to the next step. Finally, all three subjects made coding errors. Subjects A and S did not write conclusions, while subject T omitted and incompletely stated conclusions for problem two.
