Abstract

The aim of the research is to find out whether there is an increase in students' mathematical reasoning abilities with the discovery learning learning model compared to ordinary learning. The method used was quasi-experimental with a non-equivalent pretest-posttest design. The population in this study were class VIII students at SMP PGRI 1 Cimahi. The sample in this study was 30 students from class VIII-C and class VIII-D for each class. Class VIII-C is used as an experimental class and class VIII-D is used as a control class. The data collection technique in this research was through a written test consisting of six descriptive questions. The data obtained will be analyzed and processed with the help of IBM SPSS version 26 for Windows software. Based on the research results, H_0 was rejected and H_1 was accepted, meaning that there was an increase in the mathematical reasoning abilities of students whose learning used regular learning. Thus it can be concluded that there is an increase in mathematical reasoning abilities in the experimental class which uses the Discovery Learning Learning Model.

Abstract

The problem in this study is to evaluate the improvement of students' geometry skills using the GeoGebra application by focusing on two key indicators: logical thinking and drawing skills. This study employs both quantitative and qualitative methods. In the first stage, quantitative data were collected through pretests and posttests to measure student geometry skill changes. In the second stage, qualitative methods were used to explore and validate the quantitative findings through geometry skill tasks and interviews. The research subjects were second-semester mathematics education students at Bina Bangsa University, selected using purposive sampling. The findings reveal that students who engaged in geometry learning with GeoGebra experienced significant improvement in both logical reasoning and geometric drawing skills. Students became better at visualizing geometric problems, constructing geometric figures accurately, and connecting visual information to logical reasoning processes. GeoGebra improved students’ ability to identify patterns, perform deductions, draw conclusions, and visually communicate geometric ideas. It is recommended that GeoGebra be complemented with mathematical writing and drawing activities in geometry instruction to strengthen further the logical and visual dimensions of students’ geometric thinking.

Abstract

Latar belakang penelitian ini adalah siswa SMK membutuhkan suatu keahlian, kemampuan atau kecakapan untuk mengaplikasikan setiap kompetensi termasuk kecakapan matematis dalam dunia kerja. Kecakapan matematis dinilai sangat penting dan dibutuhkan dalam meningkatkan kualitas dirinya. Tujuan penelitian ini untuk melihat hasil analisis kesalahan siswa SMK dalam menyelesaikan soal kecakapan matematis pada materi bangun ruang. Subyek yang digunakan adalah 5 orang siswa kelas XII di SMK TI Pembangunan Cimahi. Bentuk pengambilan data yaitu pemberian soal tes dengan indikator berbeda pada setiap butir soal. Penelitian ini merupakan sebuah studi pendahuluan. Dari rekapitulasi perhitungan yang telah dilakukan, didapat bahwa persentase kesalahan yang paling banyak dilakukan siswa yakni 80 % pada indikator adaptive reasoning (penalaran adaptif), dimana siswa masih melakukan kesalahan dilihat dari aspek konseptual sebesar 30%, aspek prosedural juga 30% serta aspek teknik 20%. Sedangkan persentase kesalahan yang paling sedikit dilakukan siswa yakni 20 % pada indikator procedural fluency (kelancaran prosedural), dimana siswa tidak melakukan kesalahan dilihat dari aspek konseptual, tetapi pada aspek prosedural melakukan kesalahan 10% serta aspek teknik juga 10%. The purpose of this study was analyzing the answers of Vocational students on a mathematical proficiency test in three-dimensional geometry. The subjects of this study were 12th-grade students in SMK TI Pembangunan Cimahi. The data obtained from giving a test with indicators of students' mathematical proficiency that is different in each item question. This is a preliminary study. Based on the recapitulation of the results in the analysis and calculations that have been made, it was found that the most percentage of errors made by students is 80% on adaptive reasoning indicators, where students still make mistakes seen from conceptual aspects by 30%, procedural aspects also 30% and technical aspects 20%. While the least percentage of errors is 20% on procedural fluency indicators, where students do not make mistakes on conceptual aspects, but on procedural aspects and technical aspects make mistakes of 10%.

Abstract

Abstrak: Fondasi utama pembangunan suatu bangsa adalah pendidikan, karena melalui pendidikanlah kualitas sumber daya manusia dapat ditingkatkan secara sistematis dan berkelanjutan. Upaya peningkatan mutu pendidikan menjadi prioritas strategis, khususnya melalui penguatan peran calon guru penggerak sebagai agen transformasi di satuan pendidikan. Pendampingan bagi calon guru penggerak menjadi langkah penting dalam menciptakan ekosistem pembelajaran yang inovatif dan adaptif, khususnya di jenjang sekolah dasar. Untuk saat ini, tantangan pendidikan hadir dalam berbagai bentuk, seperti keterbatasan akses terhadap sumber daya pendidikan, kurangnya pelatihan berkualitas bagi guru, serta kesenjangan dalam pemanfaatan teknologi pendidikan yang dimiliki oleh guru-guru sekolah. Oleh karena itu, program pendampingan yang terstruktur dan berkelanjutan diarahkan untuk membekali calon guru SD dengan kompetensi yang mumpuni. Kegiatan ini berfokus untuk meningkatan kreativitas dalam merancang pembelajaran yang kontekstual, menyenangkan, serta relevan dengan kebutuhan dan karakteristik siswa.Selain itu, pendampingan ini juga diharapkan mampu menjawab tantangan implementasi kurikulum merdeka, khususnya dalam hal penyesuaian konten dengan kebutuhan lokal, pemanfaatan teknologi digital secara efektif, serta pemenuhan kebutuhan belajar siswa dengan latar belakang yang beragam. Melalui pendampingan pembelajaran inovatif dan pendekatan komprehensif, diharapkan memberikan perubahan positif dalam dunia pendidikan bagi calon guru SD. Perubahan ini tidak hanya akan memperkuat kapasitas guru sebagai pendidik profesional, tetapi juga memberikan dampak berkelanjutan bagi peningkatan kualitas pembelajaran dan pembangunan karakter generasi muda sebagai pilar masa depan bangsa.Abstract: One of the main foundations of a nation's development is education, as it is through it that the quality of human resources can be systematically and sustainably improved. In the Indonesian context, efforts to improve the quality of education are a strategic priority, particularly through strengthening the role of prospective teacher leaders as agents of transformation in educational institutions. Mentoring prospective teacher leaders is a crucial step in creating an innovative and adaptive learning ecosystem, particularly at the elementary and secondary school levels. Currently, educational challenges present themselves in various forms, such as limited access to educational resources, a lack of quality teacher training, and gaps in the utilization of educational technology by school teachers. Therefore, a structured and ongoing mentoring program is aimed at equipping prospective elementary school teachers with adequate pedagogical, technological, and social-emotional competencies. This activity focuses on enhancing creativity in designing contextual, enjoyable, and relevant learning that addresses students' needs and characteristics. Furthermore, this mentoring is also expected to address the challenges of implementing the independent curriculum, particularly in adapting content to local needs, effectively utilizing digital technology, and meeting the learning needs of students from diverse backgrounds. Through this innovative learning assistance and comprehensive approach, it is hoped that positive changes will be made in the world of education for prospective elementary school teachers. These changes will not only strengthen teachers' capacity as professional educators but also have a lasting impact on improving the quality of learning and developing the character of the younger generation, the pillars of the nation's future.
