The ability to think critically is one of the abilities that must be possessed by students in facing the rapid development of the times. Students' critical thinking skills can be developed through Socratic questions. This research is to find out 1) the types of Socratic questions used in learning and 2) whether Socratic questions can optimize students' critical thinking skills. The method used is a qualitative and quantitative approach with a pretest-posttest one group design. The research subjects were mathematics education students who attended linear algebra courses at Muhammadiyah Metro University. Data collection was carried out through observation and tests with descriptive qualitative and quantitative data analysis techniques. Socratic questions asked by lecturers in learning linear algebra include questions of clarification, investigative assumptions, reasons, investigative evidence, and beliefs. Socrates' questions can stimulate students' critical thinking activities to strengthen their understanding of concepts. Students' critical thinking skills increased in the medium category. The types of Socratic questions used in learning are distinguished based on three stages, namely in the introduction stage, the types of questions asked by the lecturer are clarification questions. At the core stage, Socratic questions include questions of clarification, investigative assumptions, evidence/reasons, and beliefs. And in the concluding stage, Socrates' question is a clarifying question. Socratic questions used in learning can optimize students' critical thinking skills. The results of this study are expected to be a reference for lecturers in applying Socratic questions in learning, especially in linear algebra courses.

Computational Thinking (CT) is essential for 21st-century problem-solving but remains underdeveloped in abstract mathematics courses like linear algebra. This study addresses the gap by integrating APOS theory, Realistic Mathematics Education (RME), and digital tools into a strategic learning model to enhance CT and conceptual understanding. A Design-Based Research (DBR) approach was employed to develop, implement, and evaluate the model with 73 first-year university students enrolled in a linear algebra course at Institut Bakti Nusantara. Participants were grouped by class section into experimental (APOS–RME–digital integration) and comparison (conventional digital instruction) groups. Data were collected through pre-post CT assessments, classroom observations, surveys, and learning analytics. Students in the experimental group showed significantly higher gains across five CT components—abstraction, decomposition, algorithmic design, evaluation, and generalization—compared to the control group, with medium to large effect sizes. Improved conceptual understanding of vectors and linear transformations was also observed. Learners reported high usability and perceived instructional value, particularly in contextual and interactive tasks. Implementation challenges related to digital access and skills were mitigated through structured onboarding and offline resources. The findings demonstrate that a well-integrated APOS–RME digital model can systematically develop CT and mathematical understanding. High engagement and usability support its practical viability in higher education settings. This model offers a scalable, theory-informed framework for digital mathematics instruction. Future research should explore long-term impacts, equity strategies, and cross-institutional adoption to further enhance its applicability and sustainability.
