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 aims to obtain a problem-solving profile of a two-variable linear equation system for grade VIII students of SMP Negeri 21 Palu reviewed from the student’s mathematical abilities based on Polya steps. This study uses a qualitative method with a qualitative descriptive approach based on the problem-solving steps proposed by Polya. The results of the study showed that the subjects used in this study were three students, namely students with high mathematical ability (ZN), students with moderate mathematical ability (LT), and students with low mathematical ability (KB). The results of the study showed that subjects who had high, medium and low mathematical abilities in solving SPLDV mathematical problems were as follows: (1) in understanding problems, subjects with high mathematical abilities and were reading problems repeatedly, as well as their knowledge of "statement" sentences and "question" sentences. In contrast to subjects with low mathematical skills, they can identify the information available with their knowledge of "statement" sentences and "question" sentences, but subjects with low ability cannot understand every information in the problem even though they have read the problem repeatedly, (2) in planning problem solving, subjects with high mathematical ability and have a solution plan that The same is by using a combined method between elimination and substitution. In contrast to subjects with low mathematical ability who do not have a single mathematical solution plan at all, (3) in carrying out the problem-solving plan, subjects with high and medium mathematical ability can apply problem-solving strategies according to what has been previously planned, in contrast to subjects with low mathematical ability who do not solve problems because they cannot plan problem solving, (4) In re-examining the results of problem solving, the subject with high mathematical ability re-examines the results of his work by re-examining the results step by step of each process to find the answer. Furthermore, subjects with medium and low mathematical abilities do not re-examine their work because the subject cannot solve the given problem.

Abstract

This study aims to analyze: (1) the effect of self-efficacy on student math learning achievement, (2) the effect of self-regulation on student math learning achievement, and (3) the effect of self-efficacy and self-regulation simultaneously on student math learning achievement. This research used ex-post facto method and was conducted at Tadulako University. The study population was all Mathematics Education students class of 2023 which amounted to 130 people. The sample of 98 students was selected through proportional random sampling technique. The instruments used include self-efficacy questionnaire, self-regulation questionnaire, and GPA data of the first and second semester in mathematics courses as indicators of learning achievement. Data analysis begins with classical assumption tests: normality, linearity, heteroscedasticity, and autocorrelation. Furthermore, hypothesis testing was carried out with simple and multiple linear regression analysis, F test, and coefficient of determination test. The results showed that all classical assumptions were met. The results of hypothesis testing show that self-efficacy has a significant effect on math learning achievement with a contribution of 15.5% with a p-value < 0.05  namely <0.001, self-regulation has a significant effect with a contribution of 13.1% with a p-value < 0.05 namely <0.001, and simultaneously both have a significant effect on learning achievement with a contribution of 16.7% with a p-value < 0.05 namely <0.000. Although this effect is significant, the effect is relatively small, which indicates that not only self-efficacy and self-regulation are factors that determine student learning achievement.
