Abstract

Pemilihan jurusan pendidikan yang tepat sangat penting untuk perencanaan karir, terutama bagi calon-calon guru. Keputusan pemilihan jurusan ini seringkali sulit diambil karena berbagai faktor yang kompleks. Penelitian ini bertujuan untuk mengembangkan Fuzzy Inference System (FIS) dengan metode Mamdani untuk membantu calon mahasiswa guru di universitas pendidikan dalam memilih jurusan yang sesuai. Pengembangan sistem FIS menggunakan metode RAD (Rapid Application Development). Kriteria yang digunakan untuk pengolahan data melalui FIS meliputi nilai CBT pada tahun 2023, kapasitas jurusan, dan minat mahasiswa pada tahun 2022 khusus dalam kelompok SAINTEK di Indonesia. Mamdani digunakan untuk memberikan rekomendasi berdasarkan data calon mahasiswa terkait kemampuan kognitif, literasi bahasa, dan penalaran matematis. Hasilnya menunjukkan bahwa sistem ini dapat digunakan dalam membimbing calon mahasiswa saintek dalam memilih jurusan yang sesuai dengan minat dan potensi mereka. Penelitian ini secara khusus memberikan manfaat bagi calon mahasiswa SAINTEK yang ingin melanjutkan pendidikan ke perguruan tinggi di universitas-universitas pendidikan di Indonesia, dengan memberikan panduan yang terstruktur dan sistematis untuk pemilihan jurusan. Choosing the right education major is very important for career planning, especially for prospective teachers. Choosing a major is often challenging due to various complex factors. This research aims to develop a Fuzzy Inference System (FIS) using the Mamdani method to help prospective student teachers at educational universities choose an appropriate major. FIS system development uses the RAD (Rapid Application Development) method. The criteria used for data processing through FIS include CBT scores in 2023, department capacity, and student interest in 2022, specifically in the SAINTEK group in Indonesia. Mamdani provides recommendations based on prospective student data regarding cognitive abilities, language literacy, and mathematical reasoning. The results show that this system can guide prospective science and technology students in choosing majors that suit their interests and potential. This research provides explicit benefits for prospective SAINTEK students who wish to continue their education at tertiary institutions at educational universities in Indonesia by providing structured and systematic guidance for selecting majors.

Abstract

The online learning methods used during the pandemic have impacted students' ability to communicate, collaborate, and build interpersonal relationships, which are crucial for developing collaborative skills. Students face limitations in receiving feedback and direct guidance from classmates and teachers, which affect the development of their collaborative skills. This research aims to develop STEM-Collaborative based teaching materials for arithmetic learning that can enhance students' critical thinking abilities. Research and development (R&D) approach was employed in this study using the 4-D development model. The development stages involved identification, design, and development. The research population consisted of 10th-grade students in a Vocational High School in the Bondowoso region. The research sample was selected using cluster random sampling technique, including individual trials, small group trials, and field test. Data was collected through expert validation sheets, questionnaires, and students' critical thinking ability tests. The research produced products in the form of Student Worksheets, Lesson Plans, and STEM-Collaborative Learning-based Assessment of Critical Thinking. The results showed that the developed instructional materials were valid based on expert evaluations. According to student assessments, the developed instructional materials were highly practical with a score percentage of 86%. The test results demonstrated a high improvement in students' critical thinking (n-gain = 0,703). There was a significant difference in students' critical thinking abilities between the experimental group and the control group (p < 0,05). Therefore, the developed instructional materials can be considered effective in fostering students' critical thinking. The implementation of STEM-Collaborative learning from these teaching materials has provided a positive contribution to enhancing students' critical thinking skills.

Abstract

This meta-analysis study aimed to investigate the effectiveness of ethnomathematical approaches to students' mathematical creative thinking (MCT) skills in Indonesia. Twenty-two articles in the last decade were synthesised from online databases through a rigorous selection process based on inclusion and exclusion criteria. Data analysis was carried out using a meta-analysis technique of a random effect size model using Cohen's g. This study showed that mathematics learning with an ethnomathematical approach significantly improved students' mathematical creative thinking skills with an effect size of 1.247, which is relatively large. This study does not have publication bias constraints, so the results are scientifically reliable. Therefore, this study suggests that schools in Indonesia integrate an ethnomathematical approach to mathematics learning to support students' MCT skills. Further research is recommended to develop a learning model with an ethnomathematical approach focusing on enhancing students' MCT skills.   Keywords: Meta-analysis, effectiveness, ethnomathematics, mathematical creative thinking

Abstract

Geometry learning requires a comprehensive understanding of spatial reasoning, but students face difficulty in mastering the skill. As a virtual technology, Augmented Reality (AR) offers a solution to overcome the challenges in spatial reasoning with the potential to represent and manipulate objects and develop spatial images mentally. Therefore, this research aimed to develop a mobile educational game named GEMBI AR to support students' spatial reasoning skills in geometry learning. The ADDIE model consists of analysis, design, development, implementation, and evaluation phases used to conduct research and development (R&D). The participants included six expert validators, two mathematics teachers, and eighteen eighth graders. In addition, the expert validators validated GEMBI AR in terms of quality. The result showed that GEMBI AR was valid as a geometry learning tool. According to the feedback of teachers and students, GEMBI AR was practical for educational purposes since the application positively impacted spatial reasoning. Students' spatial reasoning skills were also enhanced to compare the differences in the pre-test and post-test using Wilcoxon (Z = –3.578, p = 0.000 < 0.05). Meanwhile, the N-Gain score of 0.576, showing moderate improvement, reflected gains in spatial perception, mental rotation, and visualization. These findings suggest that GEMBI AR is a functional and valid educational resource useful for helping students develop geometric spatial reasoning. Thus, geometry learning supported by GEMBI AR has the potential to enhance spatial reasoning in secondary school.

Abstract

Many students have difficulty learning statistics, especially if they do not have a strong mathematical foundation. This study aims to analyze the influence of learning motivation and self-regulated learning (SRL) on statistics learning outcomes. The study was conducted using a quantitative approach on 50 fourth-semester students of the Early Childhood Education study program at a university in Papua, Indonesia. Data were collected through valid and reliable motivation and SRL questionnaires. The results showed that, separately, motivation and SRL did not have a significant effect on learning outcomes. However, simultaneously, both variables had a significant effect on learning outcomes. However, when combined, both significantly affected student learning outcomes, indicating that students with high motivation tended to have better SRL. These findings emphasize the importance of integrating motivational support with developing SRL strategies to improve academic achievement in statistics learning. Therefore, educational interventions that encourage motivation while strengthening SRL abilities can be an effective solution in helping students face challenges in learning statistics. Further research is suggested to explore mediating or moderating variables such as learning styles, emotional intelligence, and social support that may enrich understanding of the dynamics between motivation, SRL, and learning outcomes in various educational contexts.
