Abstract

During the learning of mathematics in SMA Negeri Benlutu, especially in class XI, teacher use WhatsApp group to send materials in .pdf format to students. Meanwhile, there is no sufficient learning media to support learning in the classroom. Therefore, the purpose of this study is to create interactive learning media, to help students understand valid, practical, and effective mathematical concepts about geometric transformation material in class XI MIPA SMA Negeri Benlutu. This research uses the research and development (R&D) method with the ADDIE development model consisting of five stages: analysis, design, development, implementation, and evaluation. The instruments used are interviews, questionnaires, and concept understanding tests. The results showed that the ThransForMath application met the three criteria of learning media feasibility: valid, practical, and effective. Valid criteria were obtained from the average validity of three material and media experts, which reached 4,7, or in the "valid" category. Practical criteria are obtained from the average practicality of all students in small and large classes, which reached 4,74 and 4,83, respectively, or in the "practical" category. Effective criteria are obtained from the results of students' concept understanding tests in small and large class trials of 100% and 88%, respectively, or in the "effective" category.

Abstract

Utilization of Whole Number Multiplication Board Teaching Aids in Mathematics Learning Multiplication Material Using the Inquiry Learning Model to Improve Student Learning Outcomes in Class IV Uptd Sdi Perumnas 1. The research problem is that learning tends to use the lecture method so that learning is less interesting which causes student learning outcomes to be low. The aim of this research is to improve the learning outcomes of class IV UPTD SDI Perumnas 1 students using the inquiry learning model by utilizing the multiplication board teaching aid. This research method uses the PTK method which consists of 4 stages, namely planning, implementation, observation and reflection. The subjects in this research were class IV B students, totaling 20 students. Data collection techniques are in the form of observation and tests, while the data analysis technique used is quantitative descriptive. The research results showed that in cycle I, the percentage of teacher activity was 64%, the percentage of student activity was 70.50% and the average student test results were 60.5 with a completion percentage of 50%. Meanwhile, in cycle II there was an increase with the percentage of teacher activity being 96%, the percentage of student activity being 80% and the average student test result being 78 with a completion percentage of 80%. Based on the research results obtained, it can be concluded that learning by utilizing multiplication board teaching aids using the inquiry learning model can improve the learning outcomes of class IV UPTD SDI Perumnas 1 students.

Abstract

This study aims to describe student’s mathematical reasoning abilities in solving trigonometry problems based on Gregorc thinking styles among XI students at SMA Negeri 1 Lobalain. The  research adopts a descriptive qualitative approach. Data collection techniques include thinking style questionnaires, test questions and interviews. The data analysis process follows the Miles and Huberman model, which consists of data reduction, data presentation and conclusion drawing. The results showed that, students with concrete sequential (SK) thinking style only fulfilled the indicators of presenting mathematical statements and using patterns and relationships to analyze mathematical situations. Students with abstract sequential (SA) thinking style are better at reasoning than students with other thinking style categories, but have not been able to fully compile and provide reasons for the correctness of the solution where abstract sequential thinkers are unable to provide reasons for the solution obtained from the problem. Students with a concrete random (AK) thinking style also did not fulfill all indicators of mathematical reasoning. They were only able to present mathematical statements and utilize patterns and relationships to analyze mathematical situations. Meanwhile, students with abstract random (AA) thinking style were only able to present mathematical statements.

Abstract

Kompetensi pedagogi merupakan salah satu kompetensi penting yang harus dimiliki seorang guru yang menjadikannya berbeda dengan profesi lainnya. Kompetensi ini menyangkut perencanaan pembelajaran, pengelolaan kelas, penguasaan teori belajar, evaluasi pembelajaran serta pendidikan karakter. Penguatan kompetensi ini menjadi kunci bagi guru dalam menciptakan pengalaman belajar yang berkualitas, mengembangkan potensi siswa, dan mencapai tujuan pendidikan secara optimal. Pentingnya kompetensi ini berdampak pada capaian hasil belajar siswa serta karakter siswa. Adapun masalah mitra ini adalah 1) keterbatasan pemahaman mengenai kurikulum merdeka dan pembelajaran berdiferensiasi, 2) kurangnya pemanfaatan teknologi dalam pembelajaran, 3) kurangnya pemahaman dalam penerapan deep learning, 4) keterbatasan dalam manajemen kelas dan pendekatan personalisasi. Solusi dari masalah ini dilaksanakan dalam bentuk pelatihan penguatan kompetensi pedagogi. Kegiatan pelatihan ini dilaksanakan bagi guru profesional lulusan PPG yang berkarya di Kota SoE dan sekitarnya sebanyak 90 peserta pada tanggal 21 Maret 2025. Kegiatan pelatihan dalam bentuk ceramah dengan materi dibawakan oleh instruktur kemudian diskusi, dan kerja mandiri. Hasil kegiatan menunjukan adanya peningkatan pemahaman tentang kurikulum merdeka, pembelajaran berdiferensiasi dan deep learning
