<![CDATA[Low learning motivation is one of the main obstacles in mathematics education, particularly due to the abstract nature of the subject, which often causes students to become passive and less enthusiastic. This study aims to improve students’ motivation in learning mathematics through the implementation of the Problem-Based Learning (PBL) model among seventh-grade students at SMP Negeri 14 Denpasar. The research employed a classroom action research (CAR) approach, conducted over two learning cycles. The study involved 41 students as participants. Data were collected through observations and learning motivation questionnaires. The results showed an increase in students’ learning motivation from an initial 38% to 70% in the first cycle and 91% in the second cycle. This improvement indicates that the application of the PBL model significantly enhances students’ active participation and enthusiasm in learning mathematics. Therefore, PBL can be considered an effective instructional strategy to address low learning motivation in mathematics among junior high school students.]]>

<![CDATA[This study aims to explore the learning styles of Mathematics Education students of the Faculty of Teacher Training and Education, Nias University in completing project-based assignments. The background of this study is based on the fact that each student has a different learning style tendency, which has a direct impact on the strategy and results of completing assignments. This study uses a qualitative approach with a case study method. The subjects of the study consisted of seven active students who were selected purposively based on their involvement in lecture project assignments. Data collection techniques include in-depth interviews, observation, and documentation. The results of the study indicate that students have a tendency towards three main learning styles, namely visual, auditory, and kinesthetic. Students with a visual style prefer the presentation of information graphically and systematically. Auditory students tend to understand the material through discussion and verbal explanation, while kinesthetic students are more active in assignments that involve direct practice. These variations in learning styles affect the way students plan, work on, and complete project assignments. It was also found that group work is more effective when each member has a complementary learning style. This study concludes that understanding students' learning styles is important for lecturers to consider in designing project-based assignments. With the right approach, the learning process will be more inclusive and meaningful for each individual.]]>

<![CDATA[This study aims to analyze the Computational Thinking (CT) abilities of prospective mathematics teacher students enrolled in the Teacher Professional Education Program at Universitas Islam Sumatera Utara. Using a descriptive quantitative approach, CT abilities were examined based on four main indicators: decomposition, pattern recognition, abstraction, and algorithmic thinking. Data were collected through contextual open-ended tests, perception questionnaires, and limited interviews involving 24 PPG students. The results showed that, in general, students' CT abilities fell into the moderate category, with the highest achievement in pattern recognition and the lowest in abstraction. Most students had never received explicit instruction in CT, yet acknowledged that this approach helped them solve mathematical problems more systematically. These findings highlight the importance of explicitly integrating CT skills into mathematics education curricula through problem-based and digital literacy-oriented learning approaches. The study recommends strengthening instructional strategies to develop students’ systematic and logical thinking abilities as future mathematics educators.]]>

<![CDATA[This research discusses the harmonious chromatic number on the Cartesian product of a path graph with three vertices (P_3) and a star graph with n vertices (S_n). Harmonious coloring is a vertex coloring of a graph such that each pair of colors appears on at most one edge. The objective of this research is to develop a harmonious coloring algorithm and also to determine and prove a general formula for the harmonious chromatic number of the graph P_3×S_n. The research method is literature-based with a mathematical approach, start from constructing modified adjacency matrices until testing the coloring algorithm. The proof is conducted through mathematical induction and structural graph analysis. The result shows that the harmonious chromatic number of P_3×S_n for n=1 is 5, for n=2,3 is 7, for n=4 is 8, whereas for n≥5, it is n+3.]]>
