Abstract

This research aims to describe students' problem solving profiles in solving story problems adding and subtracting integers based on learning styles (visual, auditory and kinesthetic) using the Polya approach. This research uses a qualitative approach with descriptive methods. The research subjects consisted of three class VII students at SMP Negeri 2 Palu, each of whom represented a visual, auditory and kinesthetic learning style. The results of the research showed that students with a visual learning style did not fully understand the problem according to the Polya procedure, even though they could state some of the information in words. -said himself. Subjects prepare plans logically and carry out steps systematically, but do not double-check the results so that there are errors that are not corrected. Students with an auditory learning style can understand problems completely and formulate plans by adding up information based on time sequence. Subjects executed plans consistently but did not thoroughly double-check results, resulting in errors being left uncorrected. On the other hand, students with a kinesthetic learning style show good understanding, prepare appropriate plans, carry out steps systematically, and recheck the results according to Polya procedures, so that they get the correct answers and are confident in the results. This research provides insight into the influence of learning styles on mathematical problem solving abilities and the importance of paying attention to the re-examination step in the learning process.

Abstract

This study aims to see how the effect of learning motivation and interest in learning on student math learning outcomes. This research was conducted at SMP Negeri 5 Palu. This research is an ex-post facto research. The population in this study were all VIII grade students of SMP Negeri 5 Palu in the 2023/2024 school year totaling 95 people. The sampling technique used was proportional sampling. The sampling technique used was simple random sampling with a sample of 33 students. Data collection was obtained through a questionnaire of learning motivation, a questionnaire of interest in learning, and the value of students' math uas results. The results of hypothesis testing show that at a significance level of 5% (1) sig value (0.000) < (0.05) then H_0 is rejected, so it can be concluded that there is a significant effect of learning motivation on the mathematics learning outcomes of students in class VIII SMP Negeri 5 Palu by 76.1% (2) sig value (0.000) < (0.05) then H_0 is rejected, so it can be concluded that there is a significant influence of learning interest on the mathematics learning outcomes of VIII grade students of SMP Negeri 5 Palu by 39.6% (3) sig value (0.000) < (0.05) then H_0 is rejected, so it can be concluded that there is a significant influence of learning motivation and learning interest of VIII grade students of SMP Negeri 5 Palu by 81.5%..

Abstract

This research aims to obtain a description of the application of the model Problem Based Learning in differentiated learning to improve the learning outcomes of class VII E students at SMP Negeri 18 Palu on triangle congruence material. This type of research is Classroom Action Research (CAR) with reference to the research design of Kemmis and Mc. Taggart, namely 1) planning, 2) implementing actions, 3) observation, and 4) reflection. The subjects in this research were 22 students in class VII E of SMP Negeri 18 Palu and 3 students were selected as informants. Data collection techniques are observation, tests, interviews and field notes. This research consists of two cycles with two meetings in each cycle which follow the PBL learning steps in differentiated learning in the phase of organizing students to learn and the phase of guiding individual and group investigations. In the phase of organizing students to learn, the teacher groups students based on academic mapping, namely (1) category 1 group (comprehensive understanding), students who understand the material completely, (2) category 2 (partially understanding), students who understand most of the material and (3) category 3 group (limited understanding), students who show very limited understanding of the material. Meanwhile, in the phase of guiding individual and group investigations, the teacher guides each group with different treatment, namely (1) category 1 group (comprehensive understanding), the teacher provides a little guidance to search for information independently because they are deemed to have been able to solve the problem given. (2) category 2 group (partially understanding), the teacher provides guidance but still leaves room for students to find their own solutions, and (3) category 3 group (limited understand), the teacherguides directly to direct students in searching for information. In cycle I the number of students who completed was 12 students with a completion percentage of 54.5% and in cycle II the number of students who completed was 18 students with a completion percentage of 81.8%. The results of observing teacher activities were in the good category with a value in the first cycle of 84% and an increase in the second cycle of 95%. The results of observing student activities in cycle I were 73% and in cycle II there was an increase of 93%. The average score in the final action test in cycle I was 68% and increased in cycle II, namely 80.7%. Based on the research results, it can be concluded that the implementation of the model Problem Based Learning in differentiated learning can improve the learning outcomes of class VII E students at SMP Negeri 18 Palu on the material of triangle similarity.

Abstract

This study is a qualitative research that aims to obtain a description of the types of errors and factors that cause errors made by seventh grade students of MTs Alkhairaat Pusat Palu in solving algebraic form problems using error analysis based on the Newman Procedure. This data was collected through written tests and interviews. The subject of this study was one student of class VII C at MTs Alkhairaat Pusat Palu who made the most mistakes. The results of this study indicate that the types of errors made by students are: (1) Reading errors, namely students cannot read the symbols contained in the problem; (2)Comprehension errors, namely students misunderstand the problem in the problem; (3) Transformation errors, namely students incorrectly determine the solution steps to be used in solving the problem; (4) Process skill errors, namely students incorrectly calculate the results of subtraction; and (5) Encoding errors, namely students incorrect in writing the final answer. The factors that cause errors made by students are: (1) students do not know the symbols in the problem; (2) lack of understanding of algebraic form material; (3) do not know the correct steps in solving the problem; (4) do not apply the concept of arithmetic operations correctly; and (5) lack of thoroughness and rush when solving the problem.
