Abstract

The factors causing students' learning difficulties are highly varied, including in mathematics education. Learning difficulties refer to the various challenges or barriers individuals face in the learning process, which can impact their ability to acquire, process, and apply knowledge and skills. Due to their diverse nature, these difficulties affect various aspects of the learning process. This study aims to describe the learning difficulties students face, particularly in mathematics education. The sample for this study comprises 25 students, specifically all students in class VIII-B. The data collection methods include tests, interviews, and documentation as supplementary data. The analysis reveals that 48% of the students fall into the "moderate" category of mathematics learning difficulties, while 40% are categorized as experiencing "difficult" challenges in learning mathematics. Specifically, in the topic of exponentiation, these learning difficulties stem from challenges in mastering and understanding the concepts, particularly in solving mathematical problems, and difficulties in number operations or lacking operational skills, leading to incorrect problem-solving. Interview results further support that students continue to experience significant difficulties in learning mathematics, especially in the topic of exponentiation.

Abstract

Learning processes and daily life are significantly influenced by reasoning ability. Specifically, in mathematics education, reasoning is crucial for students to master. Reasoning plays a vital role in the development of mathematical thinking, serving as a foundation that enables students to delve into and understand general mathematical concepts and to draw conclusions from mathematical problems. By applying a problem-based learning model, students can be assisted in solving mathematical problems related to current issues. This study uses a qualitative approach with a phenomenological perspective, aiming to analyze and describe students' mathematical reasoning abilities through the problem-based learning model. The research was conducted at SMP Negeri 4 Gunungsitoli Utara. The results showed that after the reasoning ability test, student scores varied, with the highest score being 87, the lowest 31, and an average of 63.35, categorized as moderate. The analysis identified several factors affecting students' reasoning abilities, including lack of conceptual understanding, inconsistency in problem identification, lack of precision, and difficulty in finding formulas to solve problems.

Abstract

One effective alternative for students to enhance their understanding of the concepts they are learning through systematic study activities is the use of Student Worksheets (LKPD). There are many mathematical skills that students need to develop, one of which is critical thinking. The ability to think critically in mathematics should be improved. This research employs the Research and Development (R&D) method. The R&D method is used to create a product and evaluate its effectiveness. In this study, the resulting product is the development of open-ended LKPD for the topic of Congruence and Similarity of Plane Figures for eighth-grade students. Based on the results from each validation test, the improvement from the first and second revisions by the material expert validator (Validator 1) showed a percentage increase of 18.59%, and the improvement in assessment by the Validator 1 was 12.1%. The language expert validator showed an improvement of 27.38% from the first to the second revision. The design expert validator showed an improvement of 33.47% from the first to the second revision. Furthermore, the practicality test results indicated that 89.87% of the open-ended LKPD is practical for use in mathematics instruction. Data from the learning achievement test revealed a student mastery percentage of 87%. This indicates that the development of open-ended LKPD for mathematics instruction on the topic of Congruence and Similarity of Plane Figures has a very high level of effectiveness.

Abstract

The Merdeka Curriculum is a recent initiative in Indonesia's education reform aimed at granting greater autonomy to schools and teachers in designing the learning process tailored to students' needs. Specifically, the Merdeka Curriculum is a government-driven process designed to create an environment that encourages students' active participation in learning, particularly in mathematics education. This process also involves active student engagement and reflects the outcomes of the learning experience. Student learning outcomes refer to the abilities acquired through educational activities and serve as quantitative indicators of post-learning evaluation. This study was conducted at UPTD SMP Negeri 4 Gunungsitoli Utara, specifically in Grade VIII. The research design is a qualitative descriptive study aimed at analyzing and describing student learning outcomes with respect to the implementation of the Merdeka Curriculum. Analysis of test results, which were administered to assess students' understanding of exponentiation concepts, revealed an average score of 65.74, with a mastery percentage of 70.37% and a non-mastery percentage of 29.63%. The student learning outcomes under the Merdeka Curriculum also show significant variation, depending on the preparedness of schools and teachers for implementing this curriculum.
