Abstract

Numbered Heads Together learning model is a cooperative learning model that aims to improve collaborative mathematical understanding. Mathematical communication ability is the ability to convey ideas or mathematical understanding. NHT can be applied in mathematics learning activities on campus to improve students' mathematical communication skills and is relevant or in accordance with Vygotsky's learning theory which emphasizes collaboration in learning activities. The results of the collaboration of the NHT learning model can improve students' mathematical communication skills because there is a process of social interaction and exchange of ideas in the learning model

Abstract

This study is motivated by the limited research on the relationship between the quality of educational services and student satisfaction, despite this phenomenon significantly impacting the learning experience in Islamic educational institutions. The aim of this research is to measure the effect of the quality of educational services on the satisfaction of eighth-grade students at MTs Unwaanunnajah. This study employed a quantitative approach with a survey design, involving 78 respondents selected using saturated sampling technique. Data were collected through a questionnaire and analyzed using SPSS version 29, with validity tests, reliability tests (Alpha Cronbach), normality tests, linearity tests, and simple linear regression analysis. The results indicate a positive and significant effect of the quality of educational services on student satisfaction, with an F value of 26.734 (p < 0.001) and a correlation coefficient of 0.510, which is categorized as moderate. The coefficient of determination (R²) value of 0.260 indicates that 26.0% of student satisfaction is influenced by the quality of educational services, while the remaining 74.0% is influenced by other variables. These findings support the objectives of the research and reinforce the theory that dimensions of service quality, which include responsiveness, assurance, tangibility, empathy, and reliability, play a crucial role in shaping student learning satisfaction. The main conclusion of this study is that improving the quality of educational services can enhance student satisfaction. The implications of this research include theoretical contributions to enriching the literature on the quality of Islamic educational services, as well as practical recommendations for school management to continuously improve service quality. This study also opens opportunities for further research with a broader scope and comparisons across institutions.

Abstract

Online learning requires students to possess strong self-directed learning abilities to ensure that the learning process remains effective. To ensure the accurate measurement of these abilities, an evaluation instrument with sound measurement quality is essential. This study aims to analyze the validity and reliability of the Self-Directed Online Learning instrument among secondary school students using the Rasch Model. The study employed a descriptive quantitative approach involving 757 secondary school students as respondents. The research instrument was the Self-Directed Online Learning Scale (SDOLS), consisting of 17 items measured on a five-point Likert scale. Data analysis was conducted using the Rasch Model with the assistance of Winsteps software. The results indicate that 15 items met the validity criteria based on the Outfit Mean Square (MNSQ) values, while 2 items did not meet the required criteria. Reliability analysis shows that the instrument demonstrates adequate reliability, while respondent reliability falls into the good category. These findings suggest that the Self-Directed Online Learning instrument is appropriate for measuring students’ self-directed learning in online learning at the secondary school level, although refinement of several items that do not meet the criteria is recommended.
