Abstract

Probability theory is inherently abstract and structurally complex, often creating substantial cognitive barriers for students when solving problems. This study aims to formulate a genetic decomposition of core probability concepts based on the mental structures constructed by undergraduate learners. Guided by the APOS (Action–Process–Object–Schema) theoretical framework, the research employed a three-phase methodological cycle: (1) epistemological analysis of fundamental probability concepts, (2) design and administration of diagnostic and instructional instruments, and (3) analysis and validation of students’ cognitive structures. The study was conducted at two universities in Central Java, Indonesia, involving four mathematics education undergraduates enrolled in an introductory probability course. Data were collected through content analysis, domain-specific assessment instruments, and semi-structured interviews. The APOS framework was used to trace students’ mental constructions in relation to classical probability, independence, conditional probability, total probability, and Bayes’ theorem. The results reveal that students had not fully internalized the mental objects and schemas required to coordinate these concepts during problem-solving activities. Their reasoning remained largely at the process level, particularly in representing sample spaces, applying counting techniques, and thematizing probability structures. Nonetheless, several elements of their cognitive behavior aligned with the refined genetic decomposition. The findings highlight the necessity of strengthening students’ APOS-based mental constructions to support the development of coherent probabilistic schemas and enhance conceptual as well as procedural fluency.

Abstract

The research aims to develop an inquiry learning model based on Javanese cultural ethnomathematics. This research uses research and development methods with the Plomp educational development model. Research stages include:1) preliminary research, 2) development or prototyping phase, and 3) assessment phase. In this research, the development stage was carried out at the initial investigation stage and the design stage which included field observations, literature studies, focus group discussion, preparation of learning models and learning tools and continued with small-scale trials. Field observations were carried out through observing cultural sites and junior high schools at three provinces in Indonesia, Yogyakarta province, West Java province, and East Java province. Data collection techniques in this research are interviews, observation and questionnaires. The data obtained was analyzed using quantitative descriptive analysis techniques. The development results at the initial investigation stage generated a preliminary syntax for the inquiry learning model. The subsequent design stage produced a complete mathematics learning model based on Javanese cultural ethnomathematics, documented in a comprehensive book accompanied by learning tools. Trial results indicated that the developed inquiry learning model meets valid criteria and is suitable for classroom implementation. The significance of this research lies in its contribution to integrating local cultural knowledge into mathematics instruction through an inquiry-based pedagogical approach. By embedding Javanese ethnomathematical concepts into structured inquiry learning, this study provides an innovative model that supports contextualized learning and aligns with national curriculum demands for culturally relevant pedagogy. Furthermore, the model offers a practical framework for teachers to develop meaningful learning experiences that bridge formal mathematics with students’ cultural environments.

Abstract

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.
