Evaluation and Observation

Content Quality

Rating: 4.5 stars
Strengths: Very professionally produced with good documented case studies and factual background.
Concerns: none

Potential Effectiveness as a Teaching Tool

Rating: 4.75 stars
Strengths: The overall DVD is very effective in showing potential problems, safety measures, and consequences of dust explosions. Narration is strong but stresses the learning objectives.
Concerns: May seem melodramatic

Ease of Use for Both Students and Faculty

Rating: 4.75 stars
Strengths: Need equipment or own streaming server. limits the breadth of use based on the resources available. However the purchase price ($25) is nominal.
Concerns: none

Other Issues and Comments: K-State may want to consider a talking paper to go along with the DVD. This would give the instructor a chance to stop the DVD and discuss various portions rather than sitting and watching for 30 minutes then try to go back and review.
