Longitudinal Trends in Pre University Preparation. A Cohort Evaluation Using Introductory Mathematics and Physics Courses (1980-2019)
H. R. Paz
The transition from secondary to higher education represents a critical point in academic trajectories, particularly in programmes with a strong emphasis on basic sciences. Across…
Technological Transitions and the Limits of Inference in Adaptive Educational Systems
H. R. Paz
In contemporary educational systems, academic performance indicators play a central role in institutional evaluation and in the interpretation of student trajectories. However, und…
The Stagnant Persistence Paradox: Survival Analysis and Temporal Efficiency in Exact Sciences and Engineering Education
H. R. Paz
Research on student progression in higher education has traditionally focused on vertical outcomes such as persistence and dropout, often reducing complex academic histories to bin…
When Administrative Networks Fail: Curriculum Structure, Early Performance, and the Limits of Co-enrolment Social Synchrony for Dropout Prediction in Engineering Education
H. R. Paz
Social integration theories suggest that students embedded in supportive peer networks are less likely to drop out. In learning analytics, this has motivated the use of social netw…
A Leakage-Aware Data Layer For Student Analytics: The Capire Framework For Multilevel Trajectory Modeling
H. R. Paz
Predictive models for student dropout, while often accurate, frequently rely on opportunistic feature sets and suffer from undocumented data leakage, limiting their explanatory pow…
