Abstract

Abstract. The National Examination in Indonesia has been abolished since 2020. Hence, the Indonesian Junior High School (SMP) makes its final examination items for the 9th-grade, and from the results, the school determines success in the course. The final examination has an important role and significant value in making decisions about students' graduation. Therefore, this study is aimed to analyze the Online Final Examination items in one of the public junior high schools in Bandung. The sample was 234 students in grade 9 using their mathematics examination tests, comprising 20 multiple-choice items with 4 options (A-D), while the data processing used Winsteps software with the Rasch modeling technique. Subsequently, the Rasch model results showed an acceptable people separation statistic of 1.54 and poor person reliability at 0.7<0.8. The item separation statistics was in a good category at 2.21, while the reliability at 0.83 was excellent. Although 4 online final examination items were in the fit category, 16 were good and capable of dividing students according to their abilities. They also provided very detailed data about the quality of the items and the ability of each grade 9 student. Since each test item is included in the fit category, this study contributes information on preparing and analyzing the Online Final Examination to teachers.

Abstract

STEAM-based learning (Science, Technology, Engineering, Arts, and Mathematics) is a learning approach that combines these five fields of science in one learning activity. This approach aims to develop students' critical thinking, creative and problem-solving skills. The current study seeks to analyze teacher responses in implementing STEAM-based learning media to improve the quality of learning in Riau Malay Culture subjects. This research was conducted using a qualitative approach. Data was collected through questionnaires distributed to elementary school teachers who teach Riau Malay Culture subjects in Pekanbaru City, Riau. The research results show that teachers have a positive response to the implementation of STEAM-based learning media. Teachers assess that STEAM-based learning media can improve the quality of learning in Riau Malay Culture subjects. This is because STEAM-based learning media can make learning more interesting, interactive and meaningful for students. However, it should be noted that teachers are necessary to possess a deep understanding of the STEAM approach in order to pursue effective implementation. Therefore, there needs to be support from the school in providing the facilities and infrastructure needed to implement STEAM-based learning media.

Abstract

Learning is evolving rapidly in the 21st century, as evidenced by advancements in science and technology (IPTEK), including the use of comics as a medium for learning mathematics. The incorporation of ethnomathematics comics based on the architectural features of Masjid Al-Akbar Surabaya serves as an innovative learning tool to address issues such as unengaging media and students’ reluctance to learn mathematics. This study aims to: (1) examine the process of developing ethnomathematics comics about the Al-Akbar Mosque of Surabaya to help elementary school students recognize the names and characteristics of geometric structures; (2) assess the feasibility of these comics as a learning medium; and (3) analyze teachers' and students' responses to their implementation in the classroom. This study employs a research and development (R&D) approach using the ADDIE development model, which consists of four stages: analysis, design, development, and implementation. Data collection methods include documentation, surveys, observations, interviews, and literature reviews, while data analysis combines qualitative descriptive and quantitative techniques based on expert validation and Likert-scale responses. The results indicate that (1) the three initial stages of the research process—analysis, design, and development—were successfully carried out according to the established framework; (2) validation data from material experts, linguists, and learning media specialists rated the comics as "highly feasible"; and (3) responses from class II-A teachers, expert teachers, and four class II-A students also confirmed a "highly feasible" rating. These findings suggest that the developed ethnomathematics comics based on the Al-Akbar Mosque are effective and appropriate for elementary school students in learning about geometric structures. This research contributes to mathematics education by integrating ethnomathematics into instructional media, fostering cultural appreciation while enhancing students' understanding of geometric concepts. Additionally, it provides a structured framework for developing ethnomathematics-based learning resources that can be adapted to other cultural and architectural contexts.

Abstract

Knowledge transfer is not easy especially for mathematics. Various factors need to be considered and think about how to transfer the knowledge effectively. The traditional teaching method does not help students to achieve deep learning and to solve this problem, there is a need to new learning method. The 6-questions cognitive model is a new learning model that is developed in China in 2012. This model can stand on its own or be combined with technology-based learning media. This research aims to introduce the 6-questions cognitive model by using a qualitative method. Researchers did literature research to know the deeper meaning of the 6-questions cognitive model. The result of this research shows that the cognitive model can help students to achieve deep learning and it can also be combined with a technology-based learning media. Teachers can use this research result to teach mathematics in school. Future research can find out about the effect of 6-questions cognitive model on the students' high order thinking skill.

Abstract

Several inconsistent research results regarding the effect of Problem-Based Learning (PBL) in enhancing Mathematical Abilities (MA) of primary school students have been reported widely by some researchers. To summarize, estimate, and evaluate the effect of PBL on MA of primary school students and investigate the study characteristics that provoked the heterogeneous effect size, a systematic review and meta-analysis was employed. Hedge's equation was employed to measure effect size using Comprehensive Meta-Analysis (CMA) software as an analysis tool. The synthesis of 16 relevant primary studies revealed that the overall implementation of PBL had a high positive effect (g = 1,050) significantly compared to conventional learning on MA of primary school students based on a random effect model. Moreover, the characteristics of the sampling technique, publication index, and MA significantly caused the heterogeneity of the effect size of PBL towards students' MA. Thus, these results suggest that primary school mathematics teachers should select PBL as one of the best solutions to enhance students' MA and consider the characteristics of students MA that will be improved. Besides, researchers should select random sampling as a sampling technique to select the sample and the literature indexed by Scopus as references to support the quality of research.

Abstract

This study develops an integrated video-based hybrid online learning model with problem-based learning (PBL) for Linear Algebra instruction in resource-constrained contexts. A qualitative case study with three experts and five students using thematic analysis yielded 13 codes organized into five themes: technological challenges, video characteristics, hybrid architecture, PBL implementation, and motivation strategies. Findings reveal that 100% of participants identified infrastructure constraints as primary barriers, necessitating downloadable mobile-optimized content. Optimal video specifications include 15-20 minute instructor-led explanations with embedded interactivity. The study reconceptualizes 'authentic problems' for abstract mathematics from contextual realism to conceptual genuineness, demonstrating that effective PBL engages genuine mathematical thinking—comparing representations, investigating theorems, exploring counterexamples, rather than forced real-world applications. The developed three-phase hybrid model integrates asynchronous video foundation, synchronous collaborative problem-solving, and asynchronous portfolio consolidation. Multi-stakeholder convergence on core principles provides robust design guidance, while divergences regarding scaffolding and accessibility illuminate implementation challenges. The study contributes theoretically by challenging traditional PBL frameworks for abstract domains and methodologically by demonstrating that integrating expert pedagogical knowledge with student experiential perspectives yields contextually feasible models. Practical implications address institutional digital learning policies, LMS developer feature priorities, and educator implementation guidelines adaptable across resource-constrained contexts globally.
