Relational comprehension represents a critical skill that students should acquire to correctly associate concepts. This investigation aims to cultivate a High Order Thinking Skills (HOTS)-based Student Worksheet that is both valid and practical, as well as effective, with the potential to significantly influence the relational comprehension of senior high school students. The 'design research' method, incorporating a 'formative research' development model, is used in this research, which is broken down into two stages: initial assessment and self-review. This study was carried out at Muhammadiyah 1 High School in Palembang, focusing on tenth-grade students. Data was evaluated qualitatively in a descriptive manner, founded on observations, interviews, and tests. The study's findings highlight that the developed HOTS-based student worksheet is valid, practical, and efficient in boosting students' relational comprehension once implemented in the classroom. The test outcomes indicate that students possess a reasonably good ability to comprehend HOTS category C4 problems, but are lacking in understanding HOTS category C5 problems. Therefore, additional research is deemed necessary to enhance students' understanding of HOTS category C5 problems.

Background: Mathematical modeling is an important skill in mathematics education, helping students use math to solve real-world problems. Teaching and assessing this skill can be challenging, especially when students need to apply algebraic concepts in their models.Aim: This study aims to assess the ability of high school students to model mathematical problems related to weight changes using arithmetic sequences. The focus is on how well students can understand the problem, identify relevant mathematical concepts, apply these concepts, and explain their results.Method: The study involved 28 high school students who were given two open-ended modeling tasks. A qualitative descriptive approach was used to analyze how students performed in four key stages of mathematical modeling: understanding the problem, identifying mathematical concepts, applying mathematical procedures, and explaining the results.Results: The results showed that 79% of the students reached the minimum proficiency level in mathematical modeling. Students performed very well in understanding the problem (94.05%) and identifying relevant mathematical concepts (90.48%), but had more difficulty in applying these concepts, especially in algebraic calculations (71.43%). This suggests that more attention is needed in teaching algebra within modeling tasks.Conclusion: The study highlights the benefits of using real-world contexts to improve students' mathematical modeling skills. However, it also points out the need to strengthen students' understanding of algebra to help them apply mathematical concepts more effectively. Integrating more mathematical modeling into the curriculum could better prepare students to solve complex real-world problems.

Problem-solving ability is a critical component of mathematics education, particularly in understanding Pythagorean theorem concepts. However, current instructional practices often lack integration of STEM approaches and interactive digital tools that support the development of this ability. This study aimed to develop a valid, practical, and potentially effective STEM-based Electronic Student Worksheet (E-LKPD) to enhance students’ problem-solving ability. The research employed the ADDIE development model (Analyze, Design, Development, Implementation, and Evaluation) and involved expert validation, practicality testing, and effectiveness assessment with eighth-grade students in a public junior high school following the Merdeka Curriculum. Data were collected through expert validation sheets, student practicality questionnaires, and problem-solving ability tests, then analyzed using descriptive statistics. Results showed that the E-LKPD met validity criteria with an average score of 4.20, reached a practicality level of 85.33%, and demonstrated a positive potential effect, with 57.71% of students achieving a good performance in problem-solving ability. These findings indicate that the developed STEM-based E-LKPD aligns with pedagogical and technological requirements and is suitable for implementation in mathematics learning contexts. This study contributes to digital mathematics pedagogy by offering a contextual STEM-based learning tool supported by interactive technology, addressing current needs in technology-integrated instruction.

Mathematics education in the 21st century, a field increasingly shaped by rapid technological advancement and global demands for critical thinking, necessitates the use of contextual, technology-enhanced learning media that promote higher-order thinking skills, particularly in the area of problem solving. Addressing this need, the present study focused on developing a STEM-based digital worksheet, a technology-integrated instructional tool aimed at enhancing students’ mathematical problem-solving skills within the topic of the Pythagorean Theorem. Adopting a Research and Development (R&D) framework, specifically the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation), the study involved a series of methodical phases designed to ensure both pedagogical soundness and technological relevance. Data collection involved conducting interviews and observations, analyzing relevant documents, validating content through expert review, and administering both practicality questionnaires and performance-based assessments grounded in Polya’s problem-solving rubric. Validation by three subject-matter experts, serving as evaluators of content quality and instructional alignment, resulted in an average score of 83.68%, denoting high validity. Practicality, assessed through one-on-one and small-group trials, achieved a mean score of 82.33%, reflecting strong user acceptance and ease of implementation. A field test with 30 students revealed an average problem-solving score of 75%, with notable strengths in identifying and understanding the problem, and relative weaknesses in the final stage of reviewing solutions. These findings, while preliminary, suggest that developing and implementing STEM-based digital worksheets can serve as a promising approach to fostering mathematical problem solving by embedding learning in contextual, interactive, and technologically enriched environments.

Character education plays an important role in shaping individuals who not only excel academically but also possess strong morals and high social values. In the context of mathematics learning, character values not only help students understand numerical concepts but also instill discipline, hard work, and perseverance. This study aims to analyze the implementation of character values in mathematics learning and the role of teachers in developing them. The subjects of the study were 100 high school students from public schools in Palembang. Data were collected through questionnaires and interviews and analyzed using descriptive methods. The results showed that the values of discipline, hard work, and religiosity were dominant, while creativity and communication remained weak. Therefore, efforts are needed to develop these values, particularly creativity and communication, through improved teacher professionalism, interactive learning, integration of real-world contexts, and addressing students' psychological barriers.

Character education is one of the government's flagship programs today. As part of national education, character education is expected to instil character values at all levels of education, including in mathematics, and examine how character values are applied in mathematics learning in schools from the perspective of teachers and students. Using a qualitative descriptive approach, data were collected through structured and unstructured questions asked to students at one of the selected SMA Negeri 1 Palembang. Participants consisted of 88 students, namely 58 females and 30 males, and 1 teacher who was interviewed in the data collection stage to provide views from the educator's perspective. Participants were selected purposively to ensure contextual relevance. The results of the study showed that attitude was the most dominant factor influencing students in mathematics learning, while other factors that also influenced were the role of teachers, student activity in learning, and student inactivity. To assess the effectiveness of character education in mathematics learning, this study used an exploratory learning-based approach with in-depth assessment and strengthened collaboration, so that teachers were better able to instil character values directly and indirectly.

Teachers need to improve students’ creative thinking skills by incorporating relevant everyday contexts. Soccer, as a familiar part of daily life, has not been widely used in education, and its impact on creative thinking requires further study. This research aimed to develop a contextual physics e-module centered on soccer to enhance creative thinking in physics learning. The study followed Rowntree's development model, including planning, development, and evaluation, with Tessmer’s formative evaluation through expert reviews, one-on-one assessments, small-group evaluations, and field tests. The creative thinking indicators used in the research are fluency, flexibility, originality, and elaboration. Data were collected from 346 high school students in Palembang via walkthroughs, questionnaires, and written tests, then analyzed using SPSS version 16. The results showed that the soccer-based physics e-module is valid (Sig. 0.00), practical (one-to-one: 82.75%; small group: 91.00%), and in the moderate category for improving creative thinking (N-gain: 0.59). These findings highlight the need to explore other everyday contexts and assess the long-term impact of the e-module across different educational settings.

The flexibility of mathematical thinking among prospective mathematics teachers remains relatively low, primarily due to learning approaches that do not meaningfully connect mathematical concepts with real-world contexts. This study aims to design and implement a STEM-based learning trajectory on the topic of parabolic equations to foster the development of mathematical thinking flexibility in prospective teachers. The research employs a design research approach consisting of two stages: a pilot experiment to test and refine the learning trajectory, and a teaching experiment to implement and evaluate its effectiveness. The participants were students who had completed an Analytical Geometry course. Data were collected through activity sheets, Desmos documentation, video recordings, and interviews. Data were analyzed using a retrospective analysis method, which involved three main steps: (1) organizing data from various sources, (2) conducting within-case analysis to trace students' thought processes throughout each activity, and (3) synthesizing patterns across cases to identify the development of mathematical flexibility. The results show that the learning trajectory consisting of four main activities: video analysis, elevation angle experiments, graphing parabolas using Desmos, and determining parabolic equations effectively facilitated the development of mathematical flexibility in three aspects: representational, conceptual, and procedural. Students demonstrated the ability to shift between different representations, understand the interconnections among mathematical concepts, and adapt problem-solving strategies to contextual situations. The teaching experiment also revealed increased student engagement, higher quality of discussion, and a greater diversity of strategies employed. This study recommends the integration of real-world contexts, such as football throw-ins, to support STEM-based mathematics instruction aimed at developing flexible mathematical thinking in prospective teachers.
