Abstract

The massive spread of COVID 19 has disrupted the entire system of human life, including the education system. The policy decided by the Indonesian government regarding the learning process must be based online and the university's quick response by taking the initiative to use virtual classroom-based learning. However, with virtual classroom-based learning, independence is the main keyword for the success of student learning processes. The implementation of the virtual classroom-based learning process is based on constructivism theory. Student's initial knowledge becomes important in constructivist classes in achieving learning goals. This research is pre-experimental research with one shoot case study design. Determination of the research sample by purposive sampling technique with a sample size of 33 students of mathematics teacher candidates at Majalengka University. The statistical analysis used was Anova one path. The results showed that the scale of self-regulated learning for mathematics teacher candidates differed significantly based on initial knowledge categories (high, medium, and low). This study concludes that initial knowledge is an important part of student success in virtual classroom-based learning.

Abstract

Mathematical creative thinking ability and self-efficacy are a combination of abilities students need to have when studying mathematics. Mathematical learning is expected to improve both abilities. However, teachers still use conventional learning such as direct teaching, which results in a low increase in students' mathematical creative thinking abilities and self-efficacy. So we need alternative student-centred learning and teachers as facilitators who provide scaffolding. The study was conducted to obtain a description of the discovery learning process with scaffolding which aims to improve the ability to think creatively and self-efficacy. Two quasi-experimental designs with three class groups were used: The Matching-only Pretest-posttest Control Group Design was used to measure mathematical creative thinking skills, and The Matching-only Posttest-only Control Group Design was used to measure the self-efficacy scale. Based on the results of one-way ANOVA, the mathematical creative thinking ability of students discovery learning with scaffolding is better than discovery learning and conventional learning. Likewise, this happens to 'self-efficacy, based on the one-way ANOVA that students' self-efficacy of discovery learning with scaffolding is better than discovery learning and conventional learning. The learning process of discovery learning with scaffolding has a positive impact on the improvement of mathematical creative thinking abilities and self-efficacy

Abstract

Fraction concepts represent one of the most challenging mathematical domains in elementary education, with persistent international difficulties in student comprehension despite their fundamental importance for advanced mathematical proficiency. Traditional instructional methods emphasizing rote memorization have consistently demonstrated limitations in fostering deep conceptual understanding. This study investigated the effectiveness of Problem-Based Learning (PBL) in enhancing elementary students' fraction understanding compared to conventional teaching approaches. A quasi-experimental design with non-equivalent control groups was employed, involving 38 elementary students from nine schools. The experimental group (n=16) received PBL instruction featuring authentic, real-world fraction problems requiring collaborative solution strategies, while the control group (n=22) participated in traditional direct instruction. Data collection utilized pre-test and post-test assessments measuring conceptual and procedural fraction understanding, structured classroom observations documenting engagement and learning behaviors, and student feedback questionnaires capturing motivation and confidence levels. The experimental group demonstrated substantial improvement with a mean increase of 33.25 points (Cohen's d = 3.47), while the control group showed minimal gains (7.78 points, Cohen's d = 0.91). Paired-sample t-tests confirmed statistically significant differences (p < 0.001) favoring the experimental group. Qualitative analysis revealed enhanced collaborative learning, mathematical discourse, and problem-solving confidence among PBL participants. Student motivation scores were significantly higher in the experimental group (M = 4.31 vs. 3.18). Results provide robust empirical evidence supporting PBL's superiority over traditional methods for fraction instruction. The findings validate constructivist learning principles and demonstrate that authentic problem-solving contexts facilitate deeper conceptual understanding, multiple representational thinking, and sustained student engagement, addressing persistent challenges in elementary mathematics education.

Abstract

This study aims to analyze students’ critical thinking skills in solving trigonometry problems using a qualitative case study approach. The participants were 29 twelfth-grade students from SMAN 1 Kadipaten. Data were collected through classroom observations, students’ written responses, and semi-structured interviews and were analyzed using NVivo 14 software. The findings revealed that only a small proportion of students demonstrated adequate critical thinking indicators, particularly in the areas of interpretation, analysis, inference, and evaluation. While 69% of students were able to construct appropriate mathematical models, only 31% correctly applied relevant formulas, and merely 3% succeeded in accurately stating the final answers. The interview results supported the analysis, indicating that many students faced conceptual misunderstandings, procedural difficulties, and lacked reflective thinking in validating their solutions. These findings underscore the need to enhance students’ critical thinking skills through visual learning tools, reflective discussions, and contextual problem-solving exercises. This study contributes to the development of diagnostic assessment instruments and the design of adaptive instructional strategies in mathematics education, particularly for complex topics such as trigonometry.

Abstract

This study aims to evaluate the effect of the guided inquiry method on students' adaptive reasoning ability at the secondary school level. With a quasi-experimental design using a Nonequivalent Control Group Design, class X IPS 1 applied guided discovery, while class X IPS 2 was the control with conventional learning. Adaptive reasoning ability data were obtained from pretests and posttests, then tested using paired-sample T-test. The results showed a significant increase in the experimental class (N-Gain: 0.64) compared to the control class (N-Gain: 0.55), with a significance value of 0.009. This finding indicates that the application of the guided discovery method has a more significant positive impact on improving students' adaptive reasoning ability when compared to conventional learning. The implication is that teachers and education practitioners can consider using this method to improve the quality of mathematics learning at the secondary school level. Further studies could explore specific aspects of this method and its long-term impact on student achievement

Abstract

This research aims to strengthen students' mathematical problem-solving skills by creating teaching modules based on the Discovery Learning approach. Because traditional teaching approaches often fail to engage students effectively, the development of this module is essential. In our research, we use research and development (R&D) techniques with 4D models up to the Development stage, which concentrates on module design and testing. Based on the findings of the validity test, media experts got a score of 73%, while material experts got a score of 87%. The criteria used include relevance, completeness, ease of understanding, suitability for discovery learning, and problem-solving skills. Meanwhile, practicality received an average score of 93.5% from teachers and students. Therefore, modules can be considered legitimate and useful, and are expected to improve student engagement and problem-solving skills. Through this research, it is hoped to significantly advance mathematics education with the creation of more creative teaching strategies. The findings provide a foundation for future studies to refine and expand Discovery Learning-based instructional materials in mathematics education.

Abstract

Peningkatan kualitas pembelajaran matematika menuntut guru untuk mampu merancang pembelajaran yang berpusat pada siswa, namun guru matematika SMA di Kabupaten Majalengka masih banyak yang menerapkan pola content-driven dan belum terbiasa mendesain pembelajaran berbasis riset yang memperhatikan hambatan belajar siswa. Tujuan kegiatan pengabdian ini adalah meningkatkan pemahaman dan kemampuan guru dalam merancang pembelajaran berbasis Didactical Design Research (DDR) melalui pendampingan pada forum MGMP. Metode kegiatan dilaksanakan melalui tiga tahapan, yaitu pra-workshop, pelaksanaan workshop dan Forum Group Discussion (FGD), serta pasca-workshop yang diikuti oleh 56 guru matematika SMA di Kabupaten Majalengka. Instrumen yang digunakan mencakup angket, lembar observasi, dan rubrik penilaian desain pembelajaran. Hasil kegiatan menunjukkan adanya peningkatan pemahaman, partisipasi, dan antusiasme guru terhadap pembelajaran berbasis riset sebagai alternatif selain Penelitian Tindakan Kelas (PTK). Selama kegiatan, peserta berhasil menyusun luaran berupa analisis kurikulum dan identifikasi hambatan belajar siswa. Pada tahap pasca-workshop, 85,7% peserta berhasil menyusun analisis apriori yang komprehensif, sementara 92,9% peserta telah mengimplementasikan desain pembelajaran mereka di kelas dan melakukan refleksi posteori. Kegiatan ini disimpulkan efektif dalam meningkatkan kompetensi guru SMA dalam merancang pembelajaran berbasis riset. Namun, meskipun desain pembelajaran telah siap, guru masih memerlukan pendampingan klinis lanjutan berupa coaching clinic for writing untuk mentransformasikan hasil analisis apriori dan posteori menjadi karya tulis ilmiah yang sistematis, sehingga dapat memberikan kontribusi yang lebih luas bagi pengembangan pendidikan matematika.
