Abstract

This research is quantitative. The population of this research was all of Micro Enterprises in Kulon Progo Regency. The sample of this research were 156 micro-entrepreneurs in the Kulonprogo district. This research used a simple random sampling technique to get the data. The researcher used a questionnaire as the instrument, which tested both its validity and its reliability. The data analysis technique used in this research is the Chi-Square test. The result showed, the majority of respondents had knowledge (79,5%), and the ability of financial literacy (80,8%) was categorized in the high-level category. There was a no different level of financial literacy for the micro-entrepreneur in Kulon Progo Regency based on the gender.

Abstract

Trigonometri sering dianggap sulit oleh siswa karena konsepnya yang kompleks dan metode pengajaran yang monoton. Tujuan dari penelitian ini adalah untuk membuat Kartu TrigonoMatch sebagai alat pembelajaran untuk meningkatkan disposisi matematis pada pembelajaran trigonometri. Diharapkan bahwa media ini akan dapat diandalkan dan berguna untuk pembelajaran trigonometri di sekolah menengah. Penelitian ini menggunakan metodologi ADDIE (Analisis, Desain, Pengembangan, Implementasi, Evaluasi) bersama dengan pendekatan R&D, yang difokuskan pada tahap pengembangan. Lembar validasi dan kuesioner kepraktisan digunakan sebagai instrumen penelitian. Validitas dihitung menggunakan rumus , sedangkan kepraktisan diukur dengan . Hasil dalam rentang 80%-100% dianggap "sangat valid" atau "sangat praktis." Hasil penelitian menunjukkan bahwa media Kartu TrigonoMatch "sangat valid," dengan skor 95,71% dari ahli media dan 83,7% dari ahli materi. Uji kepraktisan menghasilkan 91,67% dari guru dan 81,6% dari siswa, yang dinilai "Sangat Praktis." Media ini meningkatkan motivasi, minat, dan pemahaman siswa terhadap trigonometri sambil memberikan pengalaman yang menarik dan interaktif. Keberhasilannya disebabkan oleh desainnya yang interaktif dan mampu menarik perhatian siswa. Penelitian ini menyimpulkan bahwa Kartu TrigonoMatch memiliki dampak positif pada pembelajaran matematika dengan menyediakan alat yang inovatif dan menyenangkan, sehingga meningkatkan minat siswa terhadap matematika, khususnya trigonometri.

Abstract

This study aims to analyze students’ critical thinking skills in solving trigonometry problems using a qualitative case study approach. The participants were 29 twelfth-grade students from SMAN 1 Kadipaten. Data were collected through classroom observations, students’ written responses, and semi-structured interviews and were analyzed using NVivo 14 software. The findings revealed that only a small proportion of students demonstrated adequate critical thinking indicators, particularly in the areas of interpretation, analysis, inference, and evaluation. While 69% of students were able to construct appropriate mathematical models, only 31% correctly applied relevant formulas, and merely 3% succeeded in accurately stating the final answers. The interview results supported the analysis, indicating that many students faced conceptual misunderstandings, procedural difficulties, and lacked reflective thinking in validating their solutions. These findings underscore the need to enhance students’ critical thinking skills through visual learning tools, reflective discussions, and contextual problem-solving exercises. This study contributes to the development of diagnostic assessment instruments and the design of adaptive instructional strategies in mathematics education, particularly for complex topics such as trigonometry.
