Abstract

The objective of this simulation study was to evaluate the accuracy of item parameters estimation when employing the 3PL IRT model, mainly focusing on sample size and the length of the test (number of test items). The investigation used six datasets produced by WinGen, each comprising 5000 responses and varying test lengths within 10 to 40 items. For each dataset, the study conducted simulations and re-analyzed the data 15 times, generating a total of 2025 data subsets and estimating 225 parameters for each item. The results revealed that smaller sample sizes led to more pronounced biases, emphasizing a recommended minimum sample size of 3000 for precise parameter estimation. Additionally, the study found that a limited number of items (short test) yielded biased estimations and proposed a minimum of 25 or 40 test items for accurate estimation using the 3PL IRT model. These findings offer valuable insights for test developers in making informed decisions regarding sample sizes and test length, ultimately ensuring reliable and accurate parameter estimates.

Abstract

A study of mathematics integration with technology and Islamic values becomes an interesting topic to be studied by many scholars. The mathematics integration is essential to be applied in learning so that it can make students become Muslim individuals who have excellent character and proficiency in utilizing technology. However, there are still few studies that investigate mathematics integration with technology and Islamic values. Therefore, this study aims to describe phenomena directly related to mathematics learning that contain Islamic values and the use of technology in the learning process. The type of this study was descriptive research using a qualitative approach. The subjects of this study were three mathematics teachers who teach at Madrasah Tsanawiyah (MTs). The study procedure was carried out to find the phenomenon of research subjects that occurred at MTs. The validity of the data used the triangulation of the source and method. Data were collected through literature review, interview, and observation. The study results showed that three MTs had applied Islamic values and technology content in mathematics learning. This study recommends the need for innovation in MTs to design mathematics-integrated learning with Islamic values and the use of technology to help teachers create efficient learning, attract students' learning interest, and create an active learning environment for students.

Abstract

This research examines the digital literacy skills of teachers in Finnish education using a dataset of 4,988 teachers from 2017 to 2019. The dataset includes variables such as gender, age, level of urbanization, self-efficacy, professional development, digital engagement, and information skills. Teachers were categorized based on their digital competence. The study uses Unsupervised C-Mediums (UPFCM) clustering to analyze teachers' online experiences and identify distinct groups. Descriptive statistics and correlation analyses reveal relationships between key variables, suggesting that self-efficacy, teaching relevance, and digital engagement significantly influence teachers' digital literacy. The results indicate different digital competence profiles, providing insights into professional development needs. The study highlights the importance of personalized learning programs to enhance digital competence and bridge skill gaps. Using an advanced clustering approach, this study contributes to understanding teachers' digital skills. Provides a foundation for data-driven educational advancements aimed at increasing digital literacy in the teaching profession.

Abstract

Integrating Problem-Based Learning (PBL) with the Flipped Classroom (FC) model has gained attention as a strategy to enhance students' mathematical problem-solving skills (MPSS). While multiple studies have examined this approach, their findings show considerable variation. A meta-analysis was conducted using Comprehensive Meta-Analysis (CMA) software to synthesize findings from previous studies. A random-effects model was applied to account for variability among studies. The pooled effect size was g = 1.06 with a p-value 0.01, indicating a strong and statistically significant positive impact of the PBL-FC model on MPSS. Moderator analysis showed that the effectiveness varied significantly by media platform used (Qb = 21.98, p = 0.01) and type of publication (Qb = 7.94, p = 0.01). However, no significant differences were found regarding educational level (Qb = 7.45, p = 0.06), experimental group size (Qb = 0.29, p = 0.62), or publication year (Qb = 0.21, p = 0.64). The forest plot indicated consistent positive effects across most studies, although variations in effect sizes suggest heterogeneity due to differences in methodology, populations, or contexts. This meta-analysis confirms that the PBL-FC model significantly improves students' MPSS. Differences in media platform and publication type should be considered in future implementations. These findings provide a foundation for best practices and further research into enhancing critical thinking through PBL-FC integration.

Abstract

This research explores the transformative role of Artificial Intelligence (AI) in enhancing student engagement in higher education, specifically focusing on Educational Technology students at Yogyakarta State University, Indonesia. Through a descriptive quantitative approach, the study investigates how AI integration affects learning motivation, implementation patterns, and overall educational experiences in the digital era. A purposive sample of 25 fourth-semester students completed a structured questionnaire to assess their knowledge, usage patterns, and perceptions of AI in learning. Results revealed a high level of AI awareness (96%) and experience (100%) among students, though only 64% reported regular implementation in academic activities. Student perceptions were overwhelmingly positive, with 96% acknowledging AI's effective impact on learning, 92% reporting significant learning support, and 88% expressing intention to continue using AI in future studies. Despite these positive outcomes, the motivational aspect of AI received a comparatively lower rating (68%), suggesting areas for improvement. The study identifies AI's potential to create personalized, adaptive, and interactive learning environments while addressing concerns about over-reliance and ethical considerations. This research contributes to understanding how AI can be optimally integrated into higher education to enhance student engagement while maintaining fundamental educational values. The findings suggest that AI serves not as a replacement for educators but as a powerful complementary tool that transforms the educational landscape in the digital age.

Abstract

The demands of 21st-century education require university students to possess strong critical and innovative thinking skills. However, theoretical learning in higher education remains predominantly conventional, resulting in limited opportunities for students to construct knowledge deeply. This study aims to analyze and evaluate the effectiveness of a deep learning approach in enhancing critical and innovative thinking skills among master's level students. The research employed a convergent parallel mixed-methods design, involving 46 graduate students as research participants. Data were collected using a mixed-form questionnaire consisting of closed-ended and open-ended items, supported by documentation. Quantitative data were analyzed descriptively using percentages, while qualitative responses were interpreted thematically. The results indicate that theoretical learning still lacks variation and consistency, yet 93.5% of students reported that deep learning fosters critical thinking and 87% agreed that it encourages innovative thinking, although only 45.7% frequently apply both during coursework. Students also expect more collaborative, project-based, case-based, and exploratory learning supported by digital media. The study concludes that deep learning is a relevant and potential approach to strengthen critical-innovative thinking skills, addressing existing instructional limitations. This research implies the need for a structured deep learning model to optimize theoretical courses and create more reflective and student-centered learning.
