Abstract

This research aims to analyze students' mathematical problem solving abilities in Higher Order Thinking Skills (HOTS) on lines and angles. The research method used was descriptive analytical with the research subjects being class VIII students at MTs Ar-Raudhatul Hasanah Medan. Data was collected through a mathematical problem solving test with a focus on the HOTS aspect, namely providing a series of HOTS questions specifically designed to explore students' skills in dealing with complex aspects of Lines and Angles. The research results show that students show various levels of proficiency in solving complex problems that require critical thinking and in-depth understanding of line and angle material and that most students still experience difficulty in answering questions that require the application of HOTS. The implication of this research is to improve the mathematics curriculum at MTs Ar-Raudhatul Hasanah Medan by including more HOTS elements. This may include improvements to curriculum structure, emphasis on HOTS concepts, and integration of teaching methods that support the development of high-level problem solving

Abstract

This study aims to determine the differences in mathematical communication ability and mathematical problem-solving ability of students taught using cooperative learning models of the Student Team Achievement Division (STAD) type and Think Pair Share (TPS) type at SMP Nurul Hadina Patumbak. The background of this research is based on the low levels of students’ mathematical communication and problem-solving abilities, caused by the dominance of conventional teaching methods that have not provided students with sufficient opportunities to participate actively in the learning process. This study employed a quantitative approach using a Quasi-Experimental Design with a Non-Equivalent Control Group Design. The study population consisted of all eighth-grade students of SMP YPI Nurul Hadina Patumbak in the 2025/2026 academic year, comprising two classes. Samples were selected using purposive sampling, namely class VIII A (22 students) as Experimental Group I receiving the STAD learning model, and class VIII B (24 students) as Experimental Group II receiving the TPS learning model. The research instrument consisted of essay tests in the form of pretests and posttests to measure mathematical communication ability and mathematical problem-solving ability. Data were analyzed using the Independent Samples t-test and MANOVA with SPSS version 26.0, preceded by normality (ShapiroWilk) and homogeneity (Levene’s Test) prerequisite tests. The results showed that the mean posttest score for mathematical communication ability in the STAD class was 82.27 compared to 78.75 in the TPS class, while the mean posttest score for mathematical problem-solving ability in the STAD class was 84.09 compared to 80.21 in the TPS class. The independent t-test revealed significant differences in mathematical communication ability (t = 2.847; sig. = 0.007) and mathematical problem-solving ability (t = 3.124; sig. = 0.003) between the two classes. The MANOVA results also confirmed a significant simultaneous difference on both dependent variables (F = 7.084; sig. = 0.002). The N-Gain score of the STAD class (0.60) was higher than that of the TPS class (0.52), although both fell within the moderate category. Therefore, it can be concluded that the STAD cooperative learning model is more effective than the TPS model in improving the mathematical communication and problemsolving abilities of eighth-grade students at SMP Nurul Hadina Patumbak.

Abstract

This study aims to analyse the role of madrasah principal leadership in fostering teacher career development at MIN 1 Labuhanbatu. The background of the study highlights the persistent challenges faced by madrasah teachers in achieving the expected qualifications and professional competencies, often hindered by the lack of strategic and effective leadership. This research adopts a qualitative phenomenological case study approach, involving one madrasah principal and three teachers as participants. Data were collected through in-depth interviews, direct observation, and document analysis, and were analysed using Miles and Huberman’s interactive model of qualitative data analysis. The findings reveal that a firm yet transparent leadership style, characterised by inclusive decision-making and consistent motivation from the principal, plays a significant role in creating a positive and supportive work climate. Such leadership enhances teacher engagement, commitment, and continuous professional growth. The study concludes that effective leadership in Islamic schools is a critical factor in improving educational quality through the sustainable development of teacher careers.
