Abstract

Previous research has shown knowledge, perceptions, and attitudes are essential factors during mathematics classroom instruction. The current study examined the effects of a 3-week fraction instructional unit using concrete models, problem-solving, and problem-posing to improve elementary preservice teachers’ knowledge, perceptions and attitudes towards fractions. A quasi-experiment design was implemented to gather data via closed-ended, open-ended, and essay tasks from a convenience sampling of 71 female elementary preservice teachers during pre- and post-assessments. The study discovered that the select preservice teachers were weak in the content knowledge specifically on unit-whole, part-whole, equivalent area, arithmetic operations, and ordering fractional values. In contrast, the incorporation of concrete models, problem-solving and problem- posing was effective in improving the preservice teachers’ level of pedagogical content knowledge, perceptions and attitudes towards fractions. Implications of the results and suggestions are discussed.

Studi masa depan harus bertujuan untuk mengatasi keterbatasan. In the 21st century, Science, Technology, Engineering, and Mathematics (STEM) education is critical in building a strong workforce for the digital age. The STEM field is crucial to innovation, economic growth, and global competitiveness. However, a shortage of skilled professionals in the STEM field is a massive challenge for business and industry. The digital era has ushered in new technologies and demands for skilled workers with up-to-date knowledge and expertise. Therefore, promoting STEM education and encouraging students to pursue STEM careers is imperative. This study used a qualitative method involving four lecturers with interview data collection techniques. Research outcomes can be achieved by providing high-quality STEM education, enhancing curricula, engaging students in hands-on learning activities, and developing partnerships between industry and academia. In conclusion, investing in STEM education is critical to building a more robust workforce in the digital age and ensuring that individuals and communities thrive in the 21st-century economy. The implications of this research highlight the growing demand for a strong STEM workforce in the digital age, emphasizing the need to prioritize STEM education and training initiatives. Policymakers should allocate resources to improve STEM curricula, promote hands-on learning experiences, and encourage collaboration between educational institutions and industry partners. In addition, educators should focus on developing critical thinking, problem-solving and digital literacy skills among students to prepare them for the evolving job market. Companies should actively participate in establishing STEM education programs, providing internships and mentorship opportunities to bridge skills gaps and cultivate a highly skilled workforce. Studies may rely on limited sample sizes or specific geographic areas, which can affect the generalizability of the findings. In addition, the focus of studies on the digital age workforce may need to pay more attention to other essential sectors or future technological advances. In addition, the research does not consider the influence of cultural, socioeconomic, and gender differences on STEM education and workforce development. Future studies should aim to overcome the limitations.

Abstract

This study explores the impact of STEM integration on student performance in the Madrasah (school) Science Competition (KSM), focusing on how STEM-based learning enhances academic achievement. The growing importance of STEM education globally emphasizes its potential to improve students' scientific knowledge and critical thinking. Integrating STEM in Madrasah education, mainly through science competitions like the Madrasah Science Competition (KSM), challenges students to apply theoretical knowledge in practical, real-world contexts. Despite the increasing interest in STEM education, researchers have yet to fully understand its specific impact on student performance in KSM, particularly within the context of Islamic schools. Here, we examine how STEM integration affects student achievement in KSM. The research employs a qualitative approach, using thematic analysis to analyze open-ended questioning with students who participated in KSM. The results reveal that STEM integration on student achievement in KSM resulted in (a) scientific inquiry and problem-solving, hands-on experimentation, theoretical knowledge application, (b) use of technology and tools, and resource disparities, (c) increased engagement through STEM, and confidence in problem-solving, (d) limited access to resources, (e) collaborative learning in STEM projects, and team dynamics and support, (f) enhanced scientific understanding, and development of critical thinking skills, (g) improved KSM outcomes, and increased interest in science careers. The implications suggest incorporating STEM into Madrasah curricula can enhance academic achievement and foster critical thinking skills. Future research could explore the long-term impact of STEM integration on broader educational outcomes and investigate ways to scale STEM practices across Madrasah institutions.

Abstract

Understanding what knowledge mathematics teachers develop during lesson study is crucial for improving teaching practices and student learning outcomes. Despite widespread use of lesson study as a professional development approach, limited research has explored the specific types of teacher knowledge that emerge through this collaborative process, especially in secondary education contexts. This study explores the types of knowledge developed by mathematics teachers during the implementation of Lesson Study. Using a qualitative case study design, data were collected from three Lesson Study cycles involving four junior secondary school mathematics teachers. Data sources included classroom observations, video recordings of planning and reflection sessions, and teaching documents. Transcript-based lesson analysis was employed to examine changes in teachers’ knowledge across three key domains: mathematical content knowledge, pedagogical content knowledge (PCK), and awareness of student thinking. Findings indicate that participation in Lesson Study encouraged deeper conceptual understanding, more deliberate instructional decisions, and greater sensitivity to students’ learning processes and misconceptions. These outcomes highlight the transformative potential of Lesson Study in fostering collaborative, practice-based professional growth. The study concludes by recommending the strengthening of school–university partnerships and the institutionalization of Lesson Study as an effective and context-responsive approach to mathematics teacher development in Indonesia.
