Abstract
Undergraduate chemistry laboratory courses are delivered through hands-on exploration of the lecture material, however, students face challenges in performing the physical actions of the experiments and these are dependent on the method the instructions are delivered. A student who knows and understands proper laboratory techniques will have an easier time with the experiment, be less stressed, work more safely, obtain results that match expectations and re-enforce the lessons learned in lecture. Recently, we have re-evaluated and modified the way the laboratory technique instruction is delivered to students in our laboratory courses. In order to focus the attention of students on the proper way to use the glassware and common apparatus used in most undergraduate laboratories, a Laboratory Techniques experiment was developed as well as laboratory technique centered exercises. We will present our efforts to improve student learning, instructor observations, data and graphing skills to support the effectiveness of these initiatives.

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
