A CET Videotaped Laboratory in Materials Testing -An Evaluation and Comparison with On-campus Delivery Methods

摘要

This paper evaluates the videotaped version of the Materials Testing Laboratory course andcompares it to the on-campus version of the course. The videotaped version was first offered inthe summer of 1999 and has been offered to approximately 50 students each summer since thattime. The initial method of assessment of the course was to compare the grades of laboratoryexperiments. It was later decided that the assessment method should include a proctoredexamination with questions keyed to specific objectives.This proctored examination has been added to the course and the preliminary evaluation of theresults indicates that the videotaped course delivery is not as effective in the delivery of the 'howand why' concepts as the classes held on campus. Extenuating circumstances mandate thatadditional study of the relevant issues is appropriate. This effort is a positive outcome ofABET's mandate for continuing improvement in teaching.
