Abstract

This quantitative research with a quasi-experimental design demonstrates several significant findings regarding the quality of LAPS-Heuristic learning with performance assessment and open-ended questions of students' Mathematics’ Creative Thinking Ability (MCTA): (1) In the planning phase, the validation of learning materials and research instruments was classified as at least satisfactory; (2) During the implementation phase, the quality assessment sheets from the first to the third meetings were as at least satisfactory; (3) Student's response to LAPS-Heuristic learning combined with performance assessment and open-ended questions was notably positive, achieving a rating of 70.75%, which is categorized as strong; and (4) During the assessment stage, the results obtained from the LAPS-Heuristic learning combined with performance assessment and open-ended questions, indicate several notable findings concerning students' MCTA. First, the completion rate for students engaged in LAPS-Heuristic learning combined with performance assessment and open-ended questions surpassed 75%. Second, the average of students' MCTA who participated in LAPS-Heuristic learning, combined with performance assessment and open-ended questions, demonstrated significant improvement compared to those who participated in LAPS-Heuristic learning. Third, the proportion of experiment class students exhibiting stronger MCTA than the control class students. Keywords: MCTA, LAPS-Heuristic, Performance Assessment, Open-Ended.

Abstract

Mahasiswa cenderung kesulitan memahami konsep geometris karena pembelajaran terlalu fokus pada simbol dan rumus tanpa dukungan visual. Situasi ini menunjukkan perlunya pendekatan pembelajaran inovatif yang mampu menjembatani antara abstraksi matematika dan pengalaman konkret mahasiswa. Untuk mengatasi hal tersebut, digunakan pendekatan pembelajaran berbasis proyek yang memadukan masalah kontekstual dan media video sebagai sarana pemahaman. Penelitian ini bertujuan untuk mengeksplorasi bagaimana penggunaan video proyek berbasis masalah kontekstual dapat meningkatkan kemampuan berpikir geometris mahasiswa dalam memahami konsep integral dalam kalkulus. Penelitian ini menggunakan pendekatan kualitatif dengan desain studi kasus dengan melibatkan 30 mahasiswa semester I Program Studi Pendidikan Matematika di salah satu perguruan tinggi negeri di Jawa Tengah. Instrumen yang digunakan meliputi lembar observasi aktivitas belajar, pedoman wawancara mendalam, dan rubrik penilaian tugas proyek video yang valid dan reliabel. Data dikumpulkan melalui observasi proses pembelajaran, dokumentasi proyek video mahasiswa, serta wawancara untuk mendalami proses berpikir mereka. Analisis data dilakukan dengan kerangka kerja analisis yang melalui tahap reduksi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian menunjukkan bahwa integrasi masalah kontekstual melalui video proyek secara signifikan mendorong mahasiswa untuk menghubungkan representasi visual dengan makna integral secara geometris. Mahasiswa menunjukkan peningkatan kemampuan dalam mengidentifikasi elemen geometris, mengonstruksi model integral dari konteks nyata, dan mengkomunikasikan ide matematika secara visual dan logis. Kami merekomendasikan agar dosen kalkulus mengadopsi pendekatan pembelajaran berbasis proyek kontekstual sebagai strategi yang efektif untuk mengembangkan berpikir geometris dan meningkatkan pemahaman konsep integral dalam kalkulus.

Abstract

Understanding Students' Creative Processes in Solving Open-Ended Statistical Problems Within a Culturally Responsive Environment. Objectives: This study aims to analyze the creative thinking process in solving open-ended problems through Culturally Responsive Teaching (CRT) based on personal experience using SPSS. Methods: This qualitative case study sample consisted of 26 international students from a mathematics education program. Three subjects were selected by purposive sampling to be interviewed based on flexibility, fluency, and novelty. Data were obtained through tests and interviews (triangulation methods), which were analyzed, included data collection, analysis, research findings, and interpretation based on Wallas' theory (preparation, incubation, illumination, and verification). Findings: The four stages appeared in the creative thinking process of the three subjects, but not linearly. In the preparation, the subject showed the ability to understand the problem based on a learning experience. The incubation is characterized by the exploration of strategies, both technical (A1), contextual (A2), and structural-conceptual (A3). Illumination occurs when subjects discover new connections between methods or unexpected analysis results. In the verification stage, they not only check procedures but also encourage reflection on the meaning of the data. This dynamic shows that creative thinking is cyclical and flexible. In the flexibility, three subjects showed different approaches in combining data visualization and statistical tests, with a tendency to move between stages of thinking. On the fluency, subjects were able to generate multiple problem contexts based on learning experiences, but varied in the depth of reflection and strategy used. There were original reconstructions of ideas and problem structures on the novelty, especially when facing bidirectional data, with meaningful interpretations influenced by their respective learning experiences. The CRT appeared strong in the way subjects connected statistical data with learning experiences. It allows students to strengthen the meaning at each stage of creative thinking. The findings emphasize the importance of CRT to develop contextual creative thinking. Keywords: creative thinking, culturally responsive teaching, open-ended problem, SPSS.
