Training videos were created to assure that all staff assigned to proctor the laboratory practical would have consistent training. The practical required students to determine the density of an unknown solution. Brief videos included department staff members using both correct and incorrect procedures to determine the density. Proctors were asked to review these videos and compare them to the grading rubric (the same rubric was used for all videos). Proctors submitted their completed rubrics to the authors via email and rubrics were reviewed to ensure similar grades were given across multiple proctors. Interviews were conducted after proctoring to gauge proctor opinion of the video training process. While the videos described in the talk were used to train proctors for the laboratory practical, the authors feel that the technique could be directed at general laboratory training of teaching assistants.
