Menumbuhkan Literasi Matematis Siswa dalam Pembelajaran Melalui Lensa Konstruktivistime
No full textMathematical literacy is a key competency of the 21st century, but student achievement in Indonesia is still low. The research aims to describe the constructivism approach in fostering students' mathematical literacy. The research method is qualitative with the type of literature study through the review of reputable articles indexed by Science and Technology Index and Scopus and relevant scientific books. The results showed that students experienced obstacles in solving mathematical literacy problems, including difficulties in interpreting problems, modeling contextual problems, drawing conclusions according to context, and understanding relationships between concepts. The constructivism approach based on Piaget and Vygotsky's theories can overcome obstacles through active learning, where students build knowledge through interaction with the environment and social experiences. To foster mathematical literacy through constructivism approach, teachers need to apply three main principles, namely authentic principle, scaffolding principle, and reflective principle. The three principles form a complementary pedagogical framework for building deep conceptual understanding and mathematical problem-solving skills

Exploring the gender gap in physics learning: conceptual understanding of magnetism among indonesian senior high school students
No full textStudents' conceptual understanding of magnetism has been extensively studied, but limited research focuses on gender-based differences. This study aims to analyze Indonesian senior high school students’ conceptual understanding of magnetism and evaluate the influence of gender. A quantitative approach was applied using a conceptual test adapted from the Magnetism Conceptual Survey (MCS), consisting of ten multiple-choice items covering key concepts. Data from 120 students (57 males and 63 females) were analyzed. The average score was 66.84, which falls into the “Good” category based on predefined scoring intervals. Statistical analysis using the Mann-Whitney test revealed no significant gender difference (p = 0.836), and the effect size was negligible (Cohen’s d ≈ 0.078), indicating the difference was not practically significant. However, some concepts were particularly challenging, such as distinguishing between electric charge and magnetic poles (37.5% correct) and understanding magnetic force (45.8% correct). These findings suggest that while students generally demonstrate a good level of understanding, conceptual difficulties persist regardless of gender. Variations in learning outcomes appear to be influenced more by cognitive and contextual factors, such as item characteristics, spatial visualization skills, and mastery of basic physics concepts, rather than gender itself. Instructional emphasis should therefore prioritize conceptual clarity in these difficult areas over gender-specific strategies
