Traditional multiple-choice tests frequently fail to capture the subtle cognitive ability of mathematical abstraction in subjects like trigonometric ratio. The purpose of this study was to create and evaluate a performance-based evaluation tool to gauge students' proficiency with mathematical abstraction in the context of trigonometric ratio. Three constructed-response items made up the instrument, and each one was assessed using a unique analytical rubric that was in line with revised Bloom's taxonomy and abstraction processes. Following person-fit screening, 700 replies from 913 tenth-grade students in six Indonesian high schools were kept. Strong item fit, suitable threshold values, and high discrimination indices were found via Generalized Partial Credit Model (GPCM) analysis, demonstrating the instrument's efficacy in distinguishing between different levels of abstraction. Unidimensionality was confirmed by exploratory factor analysis, which had an excellent model fit and explained 41.0% of the total variance (RMSEA = 0.0301; TLI = 0.9775). Item difficulty levels matched the sample's ability distribution quite well, according to person-item mappings. The construct validity of the analytical rubric was further reinforced by high factor loadings and communalities. Results show that the created tool is theoretically and psychometrically solid, providing a strong means of evaluating Mathematical Abstraction in HOTS. The study demonstrates how GPCM-based analytical scoring may be used to capture complex cognitive performance and guide teaching strategies in accordance with the Merdeka Curriculum.

This study aims to analyze the Computational Thinking (CT) skills of grade IV students in mathematics learning with number materials. Based on the CT skill test conducted on 37 students at SDN Sepanjang Jaya III, the results showed that students' ability in the indicators of decomposition (53.12%) and pattern recognition (54.68%) was still in the poor category, which indicated the difficulty of students in breaking down problems into simpler parts and recognizing patterns in numbers. Meanwhile, the indicators of abstraction (60.41%) and algorithmic thinking (77.34%) showed better achievements, although still in the sufficient category. These results reveal that students have begun to be able to sift through relevant information and follow problem-solving steps systematically, but still struggle in developing algorithms for more complex problems. This study suggests that mathematics learning in elementary school needs to place more emphasis on pattern exploration, problem-based learning, and unplugged activities to strengthen students' CT skills, especially in the aspects of decomposition and pattern recognition, as well as to encourage the development of logical and algorithmic thinking skills in a more in-depth manner.

The increasing adoption of digital beauty technology through Virtual Try-On (VTO) platforms powered by artificial intelligence (AI), augmented reality (AR), and virtual reality (VR) necessitates a precise understanding of user preferences. This study aims to model user responses to VTO features using Item Response Theory (IRT), specifically the Graded Response Model (GRM) for ordinal-scale items and the Nominal Response Model (NRM) for non-ordinal categorical items. A total of 15 items were analyzed using GRM to assess users’ perceptions of AI accuracy, feature convenience, and visual satisfaction. Additionally, five non-ordinal items were modeled using NRM to capture explicit preferences for specific VTO functionalities, such as digital interaction and visual simulation. The results show that the average user preference score was 3.02 out of 5 (SD = 1.03), while the total preference score averaged 60 out of 100 (SD = 10.7), with response distributions approximately normal (skewness = 0.12; kurtosis = -0.24). The item information curves from the GRM indicated that several items contributed high information (above 2.0), effectively differentiating users within the −1 to +1 ability range. In the NRM analysis, the “real-time color visualization feature” exhibited the highest utility parameter (c = 1.98), indicating a strong user preference for this feature. The integration of GRM and NRM enables a more nuanced and flexible mapping of user preferences. This study presents a novel psychometric approach by combining GRM and NRM within a single VTO context to simultaneously capture both ordinal and nominal dimensions of user experience, which has not been extensively explored in prior research. These findings provide meaningful insights for the development of adaptive, personalized, and intelligent AI-based VTO systems to enhance the quality of user experience in digital beauty applications.

This study aims to analyze the implementation of the Game Based Learning (GBL) model in enhancing students’ mathematical creative thinking skills through a Systematic Literature Review (SLR) approach. A total of 100 articles were identified from Google Scholar and Publish or Perish, then screened through the stages of identification, screening, eligibility, and inclusion using the PRISMA guidelines. From this process, 15 articles met the eligibility criteria and were analyzed in depth. The review findings indicate that the GBL model consistently provides positive outcomes in improving students’ mathematical creative thinking abilities. Various game-based media—such as Wordwall, quiz games, board games, digital games, and Construct 2–PhET Simulation-based applications—were proven effective in encouraging students to generate flexible and original ideas, enhance problem-solving skills, and strengthen conceptual understanding in mathematics. Beyond the cognitive domain, GBL also influences the affective and psychomotor domains by improving motivation, learning engagement, and students’ motor coordination. However, the effectiveness of GBL depends on the quality of game design, alignment with the curriculum, availability of technological facilities, and teachers’ competence in managing the learning process. Overall, this study concludes that GBL is an innovative instructional model that effectively supports the development of students’ mathematical creative thinking skills. With sufficient media resources, technological support, and well-prepared teachers, GBL holds strong potential to be optimized as a learning strategy across various educational levels.
