Riemann Geometry is a difficult elective for students. The ethnomathematics approach is one way to make it easier for students to learn geometry. The aim of this research is to produce a learning theory for Introduction to Riemann Geometry through an ethnomathematics learning approach that is valid. This research method applies a research design. There are three stages, namely Preliminary Research; Prototype, and the last is the Assessment Stage. The results of this research are that the learning and its tools are valid based on validation by seven experts. In conclusion, the initial design of the learning theory for Riemann Geometry is very valid.

The proficiency of students in mathematical problem-solving skills is believed to be shaped by factors such as mathematical concepts understanding, creative thinking skills, and self-efficacy. This research endeavors to investigate the interplay among self-efficacy, mathematical concepts understanding, creative thinking skills, problem-solving skills, and mathematics learning outcomes. Employing a survey approach, the study encompasses all ninth-grade students in Central Bengkulu, Bengkulu, Indonesia, with a sample of 100 students selected through proportional stratified random sampling. Data collection involves Likert scale instruments for self-efficacy, along with tests for mathematical concepts understanding, creative thinking skills, and problem-solving skills. Path analysis techniques are applied for data analysis. The findings of the research indicate that mathematical concepts understanding, creative thinking skills, and problem-solving skills collectively exert a positive influence on mathematics learning outcomes. Additionally, it is demonstrated that self-efficacy, understanding mathematical concepts, and creative thinking skills collectively contribute positively to problem-solving skills. Furthermore, the research reveals a direct positive influence of self-efficacy on both mathematical concepts understanding and creative thinking skills.

This research aims to determine whether there is a positive correlation between mathematics learning habits through an ethnomathematics approach and entrepreneurial behavior. This research is survey research conducted by mathematics education students in Bengkulu and Lubuklinggau. The sample for this research consisted of 70 students. There are two questionnaires as research instruments. Both are a questionnaire on mathematics learning habits using an ethnomathematics approach, and an entrepreneurial behavior questionnaire. The result of this research is that the complete structural equation model fit test is a good fit, which means that the empirical structural equation model is suitable with the theoretical (conceptual) structural equation model. The results of the hypothesis test show that the calculated t value is 11.364 > 1.96, which means Ho is rejected, meaning that this research hypothesis is accepted. The conclusion is that there is a positive correlation between mathematics learning habits through an ethnomathematics approach and entrepreneurial behavior.

Purpose: This study examines cognitive transitions and epistemological obstacles in undergraduate mathematics education by testing an integrated APOS and SOLO+ framework within formal ε-δ limit proofs. Method: Using an explanatory sequential mixed-methods design, CB-SEM analyzed data from 278 undergraduates to test theoretical structural relationships. Qualitatively, a "diagnostic task analysis" employing the Constant Comparative Method examined task-based interviews from 8 key informants to dissect transitional cognitive anomalies. Findings: CB-SEM confirmed that Structural Complexity (SOLO+) significantly partially mediates the effect of Cognitive Mechanisms (APOS) on Proof Proficiency, explaining 62.4% of the variance. Qualitative autopsies identified two specific transitional traps: Interiorization Instability (Semi-Relational level), marked by universal quantifier failures and reversed logic in linear tasks; and Encapsulation Rigidity (Semi-Extended level), marked by intuitive blockages during bounding strategies in non-linear tasks. Consequently, a grounded taxonomy was generated to distinguish superficial syntactic "slips" from deep-seated epistemological "errors." Significance: This framework shifts pedagogical evaluation from outcome-based syntax to transitional cognitive diagnosis, providing a powerful blueprint for addressing learning barriers and laying the theoretical foundation for future diagnostic tools.
