Abstract

This study is motivated by students' low critical thinking skills, particularly in three-dimensional geometry. Moreover, the limited availability of effective interactive learning media impedes the development of these skills. Three-dimensional geometry requires a more engaging and interactive approach to enhance understanding. This study aims to develop GeoGebra-based learning media within the Problem-Based Learning model to enhance students' critical thinking skills in mathematics. The research method employed is Research and Development using the ADDIE design model. The study subjects consist of eighth-grade students. The research instruments include validation sheets, practicality questionnaires, and tests. The validation results indicate that the GeoGebra validation score is reaching 95.16% (highly valid). The practicality test showed an average score of 96.09% (highly practical). The obtained N-Gain score of 0.7655 (high category) indicates an improvement in students' critical thinking abilities. The findings of this study conclude that the use of GeoGebra in PBL-based learning is effective in enhancing students' mathematical critical thinking skills and can serve as an innovative alternative for teaching three-dimensional geometry. The findings of this study have positive implications for enhancing students' critical thinking skills through the integration of interactive learning tools such as GeoGebra, which can improve engagement and understanding in mathematics.

Abstract

Literasi numerasi dan literasi finansial merupakan kompetensi penting yang perlu dimiliki oleh mahasiswa calon guru matematika dalam menghadapi tantangan kehidupan dan pembelajaran abad ke-21. Literasi numerasi berperan dalam kemampuan memahami dan menggunakan informasi kuantitatif, sedangkan literasi finansial berkaitan dengan pengambilan keputusan keuangan yang tepat. Penelitian ini bertujuan untuk mengeksplorasi hubungan antara literasi numerasi, literasi finansial dan efikasi diri matematika mahasiswa calon guru matematika. Penelitian ini menggunakan pendekatan kuantitatif dengan metode korelasional. Subjek penelitian adalah mahasiswa program studi pendidikan matematika yang dipilih menggunakan teknik purposive sampling. Data dikumpulkan melalui instrumen tes literasi numerasi dan angket literasi finansial. Analisis data dilakukan menggunakan uji korelasi Pearson. Hasil penelitian menunjukkan bahwa terdapat hubungan yang tidak signifikan antara literasi numerasi, literasi finansialdan efikasi diri matematika mahasiswa calon guru matematika. Temuan ini mengindikasikan bahwa pembelajaran matematika di LPTK perlu dirancang tidak hanya untuk meningkatkan kemampuan numerasi dan efikasi diri, tetapi juga perlu mengintegrasikan konteks finansial secara eksplisit agar literasi finansial mahasiswa calon guru matematika dapat berkembang secara optimal.

Abstract

Indonesian Migrant Workers (PMI) in Brunei Darussalam face limited access to continuing education, lack of entrepreneurial skills, and insufficient understanding of the integration between education, ecology, and business. To address this gap, the FMIPA team from Universitas Negeri Surabaya conducted an online EduEcopreneurship training in November 2025. The activity employed a participatory workshop approach and a pretest-posttest evaluation design. Results indicated a significant improvement in participants’ conceptual understanding, with average scores rising from 52.4 to 84.2 (a 31.8-point increase, or 60.7%). Moreover, 93.3% of participants successfully designed business ideas that integrated the three core pillars of EduEcopreneurship: Eco-Innovation, Eco-Opportunities, and Eco-Commitment. Participant feedback was rated “Good” (average 4.08 on a 5-point scale). These findings confirm that EduEcopreneurship serves as an effective dual empowerment model,combining non-formal education and sustainable economic development,for migrant workers.
