Abstract
Laboratory-based learning can be weakened by a lack of connection with underlying theory and limited contextualization to enhance motivation. To address these shortcomings, a framework for the development of web-based multimedia prelaboratory modules is proposed. The framework incorporates supportive information (content), utility value (context), multimedia design principles (design), and questions/explanatory feedback (formative assessment). On the basis of this framework, prelaboratory modules were developed for three second-year organic chemistry experiments in a chemical engineering course. Each module consists of a few short animation videos and a few questions. The videos include explanation of theories and justification for experimental procedures (supportive information), as well as explanation of utility value to increase student motivation. The effectiveness of the modules was assessed through multiple strategies including a survey with learning and utility value/motivation constructs, student grades for the modules, time spent on the modules, and the number of times videos were watched. Students in general expressed positive views regarding the prelaboratory modules in terms of understanding and relating theory to procedures, and understanding the utility value of the material. Half of the students reported increased motivation as a result of understanding the utility value of the knowledge they acquired. Thus, prelaboratory exercises based on this framework may alleviate some of the educational challenges in undergraduate laboratories.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
