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

This study explores the impact of principals’ human resource management (HRM) competencies on elementary school teachers’ performance in Majalengka Regency, Indonesia. Given the strategic role of school principals in managing educational resources, especially teachers, this study aims to examine how specific dimensions of HRM competencies contribute to teacher performance. A quantitative, correlational research design with a cross-sectional survey approach was used. The study involved 400 teachers from 80 public elementary schools selected through proportionate stratified random sampling. Data were collected using validated questionnaires measuring HRM competencies (six dimensions) and teacher performance (four dimensions). Statistical analyses included descriptive statistics, Pearson correlations, simple and multiple linear regressions, and Structural Equation Modeling (SEM). The findings revealed that principals’ HRM competencies significantly influenced teacher performance (R² = 0.615, p < 0.001). Among the HRM dimensions, human resource development had the strongest effect (β = 0.402), followed by performance appraisal (β = 0.234) and HR planning (β = 0.203). Teacher performance was generally high, particularly in personality and pedagogical competencies. All regression assumptions were met, confirming the robustness of the analysis.The results suggest that effective HRM by school principals, especially in continuous professional development and fair performance evaluations, plays a pivotal role in enhancing teacher performance. However, compensation and work relationship dimensions showed room for improvement, indicating potential policy gaps. Principals’ HRM competencies are vital for improving teacher performance. Educational policymakers should prioritize leadership development programs focusing on HRM strategies to strengthen teacher quality and educational outcomes at the elementary level.

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

The development of critical thinking skills at the elementary school level is a foundational component in preparing students to navigate complex, real-world problems that demand analytical reasoning, evaluative judgment, and effective problem-solving. This study investigates the efficacy of an interactive e-module grounded in Problem-Based Learning (PBL) principles in enhancing the critical thinking abilities of fourth-grade students, with a particular focus on mathematics and science instruction. A quasi-experimental design was implemented, comprising an experimental group that utilized the PBL-based e-module and a control group that received conventional instruction. Data collection methods encompassed pre- and post-tests measuring critical thinking performance, observational protocols documenting student interaction with the module, student perception questionnaires, and semi-structured interviews with both students and teachers to elicit qualitative insights. The findings indicate that students in the experimental group exhibited significantly greater gains in critical thinking skills, as evidenced by a substantial improvement between pre- and post-test scores. Moreover, these students engaged more actively in collaborative discussions and problem-solving tasks relative to their peers in the control group. The results underscore the effectiveness of PBL-based e-modules as pedagogical tools for fostering critical thinking at the elementary level. The study's implications point to the transformative potential of integrating PBL frameworks into digital learning environments to enhance educational quality and student engagement in primary education settings
