Abstract

Learning algebraic structures is often considered difficult for students to understand because of its abstract and theoretical nature. Without the right approach, students can find it difficult to relate theory to practice and master the basic concepts in algebraic structures. This article aims to examine the effectiveness of the application of the scaffolding method in learning algebraic structures. This study uses a qualitative approach by collecting main data through interviews with students of Mathematics Education at HKBP Nommensen University. The data analysis techniques used include data interpretation, data reduction, and conclusion drawn. The findings of the study show that the application of scaffolding provides more effective understanding for students, helping them overcome difficulties in learning complex material. In addition, scaffolding also increases students' interest in learning and makes learning algebraic structures more fun. Thus, this study confirms that scaffolding is an effective method to increase understanding and motivation for learning in learning algebraic structures.

Abstract

This research aims to examine conceptually how the Independent Curriculum is implemented in learning practices in schools, especially in shaping student character through the dimension of the Pancasila Student Profile. This study uses a literature study method with a descriptive-qualitative approach, which combines the analysis of policy documents and the study of educational theory. The results of the study show that the Independent Curriculum presents a learning system that is oriented to the principle of "independent learning", which provides freedom for students to explore their potential according to their interests, talents, and learning needs. The teaching tools used, such as the Pancasila Student Profile Strengthening Project, not only support academic aspects, but also instill spiritual, social, and moral values in depth. Thus, learning in the Independent Curriculum not only focuses on the transfer of knowledge, but also the formation of a whole human being who has a strong spiritual foundation and is able to contribute to the life of the wider society.

Abstract

This study aims to determine the effect of the Discovery Learning model on students’ mathematical conceptual understanding in grade VIII of SMP Negeri 4 Pematangsiantar. The sample of this study was class VIII-10 consisting of 30 students. The research instruments were a questionnaire and a test. The questionnaire was used to identify the implementation of the Discovery Learning model, while the test was used to measure students’ conceptual understanding of linear equations. The instruments consisted of 20 questionnaire items and 4 test items, which had been validated and declared reliable. The research design employed a one-shot case study. Data analysis included prerequisite tests (normality and linearity) and simple linear regression analysis. The results of the study showed the regression equation Y=6.571+0.411XY = 6.571 + 0.411X. The significance test revealed that tcount>ttablet_{count} > t_{table} (8.194 > 2.048) and sig. value < 0.05 (0.000 < 0.05), indicating a significant effect of the Discovery Learning model on students’ mathematical conceptual understanding. The contribution of variable X (Discovery Learning model) to variable Y (mathematical conceptual understanding) was 70.6%..

Abstract

This study aims to determine the effect of the Contextual Teaching and Learning learning model on students' mathematical critical thinking skills at Cinta Rakyat 3 Private Junior High School, Pematangsiantar. This study uses a quantitative approach. The method used by the researcher is an experimental method. This research method was chosen to see how much influence the Contextual Teaching and Learning learning mode has on students' mathematical critical thinking skills on the material of curved cylinder side solids at Cinta Rakyat 3 Private Junior High School, Pematangsiantar. Based on the results of data analysis and discussion, it can be concluded that there is a positive and significant influence of the use of the Contextual Teaching and Learning learning mode on students' mathematical critical thinking skills on the material of curved cylinder side solids, grade IX of Cinta Rakyat 3 Private Junior High School, Pematangsiantar. This influence is shown through the regression equation Y = 22.457 + 0.743X with b = 0.743. By using the t-test, namely t_calculated > t_table = (10,364 > 3,583) it shows that the significance and by using the coefficient of determination it can be seen that the influence is 79.3%.

Abstract

This study aims to determine the Effect of Thinking Aloud Pair Problem Solving (Tapps) Method on Mathematical Communication Skills of Students of HKBP Private Vocational School Pematangsiantar. The type of research used by the researcher is experimental research. Experimental research is a research to determine whether there is an effect of something imposed on the subject of investigation. This research will be conducted using a single case study design (one-shot case study), where one group of experimental classes becomes the research subject. In the experimental group, a treatment is applied in the form of the application of the Thinking Aloud Pair Problem Solving (TAPPS) Learning Method which is considered successful. After the treatment, a post-test evaluation is carried out and from the results of the measurement, conclusions will be drawn. Based on the results of data analysis and discussion, it can be concluded that there is a significant influence of the Thinking Aloud Pair Problem Solving (TAPPS) Method on students' mathematical communication skills in Statistics material at HKBP Private Vocational School Pematangsiantar. This influence can be seen from the regression equation = -56.532 + 1.088 with a regression coefficient of 1.088 and a determination coefficient of 91% which shows that there is a very strong relationship between the Thinking Aloud Pair Problem Solving (TAPPS) Method and students' mathematical communication skills

Abstract

This study aims to critically analyze the implementation of the Kurikulum Merdeka (Independent Curriculum) in mathematics education, focusing on the alignment between policy discourse and classroom practices. Utilizing a literature review approach, this research examines relevant national and international sources and synthesizes findings related to the challenges, innovations, and reflective practices surrounding the curriculum implementation. The analysis reveals that although the Kurikulum Merdeka promotes flexible, contextual, and student-centered learning, its practical application still encounters pedagogical, cultural, and structural barriers. Innovations such as project-based learning, ethnomathematics integration, and digital media utilization offer promising strategies, yet these remain hindered by insufficient teacher readiness and systemic support. This study recommends strengthening teachers’ professional capacities, transforming school learning cultures, and conducting further practice-based research to authentically embed the spirit of independent learning into mathematics instruction in a sustainable manner.
