Abstract

Despite the rapid expansion of multimedia-based learning in education, the availability of psychometrically validated evaluation instruments remains limited, underscoring the urgent need for reliable, standardized measurement tools. This study aims to develop and validate a multimedia-based learning product evaluation instrument that measures three main constructs: feasibility, practicality, and attractiveness. The study used an instrument development design with an integrated psychometric approach that combines classical measurement theory (Classical Test Theory), Structural Equation Modeling (SEM), and the Rasch Model. Content validity was assessed using expert judgment, as measured by Aiken's V coefficient and the Content Validity Ratio (CVR). Construct validity was tested through Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA). Structural analysis was conducted to examine the relationships between constructs, and multi-group analysis (teachers and students) was conducted to test model invariance. Data were collected from 257 respondents, comprising 153 students and 104 teachers. The results showed that the instrument had high content validity (mean Aiken's V = 0.89), very high reliability (α = 0.93), and a good measurement model fit (CFI = 0.96; RMSEA = 0.054). Rasch analysis showed item reliability of 0.96, and no serious misfit was found. Multi-group analysis showed the model was invariant between teachers and students. Thus, this instrument meets modern psychometric standards and is suitable for use in evaluating multimedia-based learning products.

Abstract

This study investigates the effectiveness of inquiry-based virtual experiments in improving elementary students' cognitive skills and science process skills in learning electricity concepts. The integration of digital simulations into elementary science instruction has become increasingly important for supporting conceptual understanding and scientific inquiry, particularly for abstract topics such as electricity. The population consisted of sixth-grade students at a public elementary school, from whom 25 were selected using purposive sampling based on technological readiness and curriculum alignment. The study employed a quasi-experimental design using a one-group pretest–posttest approach. The learning intervention was implemented through four inquiry-based sessions using PhET Interactive Simulations (Circuit Construction Kit: DC). Data were collected using two validated multiple-choice instruments: a 17-item cognitive test aligned with five levels of Bloom's Revised Taxonomy and an 18-item science process skills test measuring six indicators, including observing, classifying, predicting, interpreting data, drawing conclusions, and communicating. The instruments demonstrated good internal consistency (KR-21 = 0.83). Data were analyzed descriptively by comparing pretest and posttest scores. The results showed an increase in students' posttest mean scores, reaching 79.3% for cognitive skills and 73.1% for science process skills.

Abstract

Many students exhibit low levels of critical thinking and motivation for learning, indicating the need for innovative instructional approaches. This study aims to examine the impact of Numbered Heads Together (NHT) learning using Google Sites on students' critical thinking and motivation to learn. This research was conducted in two high schools in Yogyakarta. This study employed a quantitative quasi-experimental design, involving students from 11th-grade science classes. The experimental group learned NHT on Google Sites, whereas the control group received instruction using a scientific approach. The sampling technique uses a cluster random sampling. The research instrument uses a test and a questionnaire, and data are collected through pretest and posttest measures. Furthermore, the data were analyzed using MANOVA. The results from hypothesis tests showed significant differences in students' critical thinking and motivational learning, both simultaneously and separately, between students who were given NHT-Google Sites and those who were given a scientific approach, with a simultaneous effective contribution of 31.4%, which is categorized as large. and separately, 26,2% for critical thinking skills and 14,8% for student learning motivation, each of which was in a large category. Overall, students' critical thinking and motivation to learn in NHT using Google Sites were higher than those of students who received instruction using a scientific approach. These findings suggest that the Numbered Heads Together learning model, when implemented with Google Sites, can be an effective instructional strategy for enhancing students' critical thinking skills and motivation to learn.

Abstract

This study reconstructs the Poda Na Lima philosophy into a contextual school leadership framework to bridge the gap between formal administrative demands and local cultural values. The objective is to analyze how these indigenous values are interpreted and implemented by school principals in North Tapanuli. Using a qualitative exploratory design, the study employed purposive sampling to select 15 participants (3 principals, 9 senior teachers, and 3 community leaders) from the elementary school population. Data were gathered through in-depth interviews, field observations, and document analysis. Results indicate that Poda Na Lima encompasses five dimensions: leadership accountability, teacher professionalism, infrastructure management, environmental development, and social ethics. These values are operationalized through transparency, role modeling, and ethical communication within the school community. In conclusion, integrating indigenous wisdom fosters a contextual leadership model that strengthens school governance and social harmony. It is recommended that local education authorities integrate this framework into leadership training programs to enhance culturally-responsive school management.

Abstract

Prospective teachers should participate in pedagogical competency programs and engage in teaching practice to become professional teachers. The urgency of this study lies in examining the factors that influence career choices and assessing the quality of future professional teachers. This study investigates the effects of career self-efficacy (SE) and career interest (CI) on career choice (CC), with career exploration (CE) as a mediator, during the teaching internship. The population was 675 accounting education students who participated in the teaching internship program. The study used a simple random sampling method, yielding 251 respondents. The questionnaire included the career decision-making career self-efficacy scale-short form (CDMSE-SF), career exploration survey (CES), and career choice. A quantitative approach using structural equation modeling (SEM) was employed in WarpPLS 5.0. The study results show a direct relationship between career self-efficacy, career interest, and career exploration on career choice. Career exploration at the teaching internship also mediates the relationship between career self-efficacy and career interest in teaching career choice. It indicates that teaching internship programs increase students' confidence, thereby strengthening their resolve to pursue a career as an accounting teacher. Future studies may also explore other variables such as outcome expectations and personal background factors.

Abstract

As technology integration has become increasingly central to contemporary education, the need for valid and contextually fair instruments for assessing teachers' Technological Pedagogical Content Knowledge (TPACK) has become more urgent. This study aimed to develop and comprehensively validate a TPACK self-assessment instrument for Indonesian in-service teachers. A total of 1,297 teachers selected through purposive and convenience sampling from diverse provinces, school levels, and geographic locations participated in the study. The 48-item instrument, distributed across seven TPACK dimensions (TK, CK, PK, PCK, TCK, TPK, and TPACK), employed a 4-point Likert scale. Psychometric evaluation followed a multistage approach: (a) construct validity via corrected item-total correlations, in which all items met the r ≥ .30 threshold (range: .57–.79); (b) internal consistency reliability using Cronbach's alpha, with all dimensions exceeding .70 (α = .78–.97); (c) exploratory factor analysis (EFA), which supported the theoretical factor structure (KMO = .968; Bartlett's χ² = 54,279.51, p < .001); (d) confirmatory factor analysis (CFA), which yielded marginal fit indices (CFI = .707; RMSEA = .107), suggesting the need for model refinement; and (e) differential item functioning (DIF) analysis, which revealed minimal gender-based bias but notable location-based DIF. Overall, the instrument demonstrated strong psychometric properties for measuring teachers' TPACK in the Indonesian context. The findings highlight the importance of refining TPACK instruments to ensure greater measurement fairness across diverse educational settings and support future teacher professional development initiatives.
