Blended Guided-Inquiry General Chemistry Laboratory Course: An Introduction to Chemical Research
Bibliographic record
Abstract
In the face of increasing constraints on funding and laboratory space, chemistry educators must find ways to creatively marshal their resources to effectively teach introductory chemistry students the knowledge and skills they need despite these challenges. This has been the goal of the First-Year General Chemistry Laboratory at the University of British Columbia, which maximizes students’ preparation for their limited time in lab using a combination of online and face-to-face guided inquiry for a large number of students. The theme of the laboratory course, an introduction to scientific research, provides a framework from which to teach students basic, transferable chemistry research skills: proposing scientific questions, formulating hypotheses and designing experiments to test them, finding pertinent information in scientific literature, learning experimental techniques, keeping a laboratory book and recognizing safety issues. The first term teaches basic laboratory skills and record keeping, to prepare the students for investigative projects in the second term. The blended guided-inquiry approach provides students with tools that they will be able to confidently apply in a variety of new situations by giving them a deep understanding of the scientific process.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
