Abstract

Kemajuan ilmu dan teknologi saat ini menuntut para guru agar melek teknologi. Dengan pemahaman dan penggunaan teknologi dengan baik diharapkan berimplikasi pada siswa yang diajar. Siswa perlu dibekali dengan pengetahuan dan pemahaman teknologi yang tepat guna dan berhasil guna, agar mampu menerapkan teknologi dalam menyelesaikan permasalahan dalam kehidupan sehari-hari. Salah satu pendekatan pembelajaran yang melibatkan teknologi dan ilmu pengetahuan adalah pendekatan pembelajaran berbasis STEAM. Kegiatan pengabdian ini dilaksanakan dengan tujuan untuk meningkatkan kemampuan dan pemahaman guru-guru SD Negeri Emereuw Kota Jayapura dalam merancang, membuat, dan menerapkan pembelajaran berbasis STEAM. Hasil pengabdian menunjukkan bahwa (1) Pelaksanaan kegiatan berjalan dengan lancar, (2) Semua peserta mampu memahami materi yang disampaikan, dan (3) Guru/peserta dapat memahami pendekatan pembelajaran berbasis STEAM melalui kegiatan simulasi.

Abstract

Teacher communication is critical in mathematics learning, influencing students’ understanding, engagement, and academic success. This study explores the communication practices of novice, intermediate, and senior mathematics teachers when teaching trigonometric comparisons in right triangles. Using a qualitative exploratory design, classroom observations and interviews were conducted with three vocational high school teachers in Keerom Regency, Papua Province, Indonesia, focusing on five communication aspects: clarity, assertiveness, responsiveness, relevance, and presentation style manipulation. The findings reveal significant differences among the teacher groups. Novice teachers exhibited excellent communication by integrating prerequisite knowledge, employing visual aids, and connecting lessons to real-world applications. Intermediate teachers demonstrated structured but conventional communication methods, focusing on content delivery with limited interactivity. Senior teachers, while experienced and accurate, relied heavily on traditional lecture-based approaches and displayed limited responsiveness to student needs. This study highlights the strengths of novice teachers’ student-centered strategies, such as group activities and guided discovery, which enhanced student engagement and comprehension. The research underscores the need for professional development programs to promote innovative teaching practices across all experience levels. Future studies should examine how professional growth and contextual factors influence teacher communication, contributing to improved mathematics learning outcomes.       Keywords: teacher communication, vocational school, trigonometry, teaching experience. DOI: http://dx.doi.org/10.23960/jpmipa/v25i4.pp1854-1869

Abstract

Based on the experience of the researchers taught the subject of Economic Mathematics many students who have not been able to solve the problem solving. One alternative that can be used to solve the problem is by using Polya steps. When solving a mathematical problem, each student has a different way of thinking. The difference is possible because of differences in student cognitive style. The cognitive styles used in this research are Field Independent cognitive style and Field Dependent cognitive style. The material chosen in this research is the demand function, the Bid Function, the Savings Function and the Taxation Function. This research is a descriptive research with qualitative approach which aims to describe the problem solving ability of student mathematics using Polya steps in terms of cognitive style of FI and FD. Subjects in this research are students of VI semester of Mathematics Education Program. Technique of taking research subject is by purposive sample. The results showed that FI subject understood the problem well. In the planning step, the FI subject can analyze the information received. Subjects use previously learned information and solve problem-solving given to the problem as planned and check back on each question. The subject of FD can not receive information and understand the problems that exist in the problem and can not process information/do not understand the purpose of the problem. In the planning step, the subject of FD is unable to think how to solve the problem and is not accustomed to rechecking
