Analysis Summary 1

• ChE performed above that of national average in– Process Equipment Design– Ethics– Engineering Economics– Material Science/Strength of Material

42

Analysis Summary 2

• Passing rate of our students has been steadily declining over the past years (70% in 2004)

• UTK/ChE performs below that of national in quite a few subject matters in most years

• Weakest performance in– Circuit, fluid mechanics, and statics– Material and Energy Balance– Heat and Mass Transfer– Transport– Computer and numerical methods

43

Possible Means for Improvement

• Formal orientation period at the beginning of ChE401• Letter grades from A to F• Continued stress of FE in junior and senior/fall courses• No retake of 401 exam allowed; • Homework problems (shoing work) for each topic

(multiple choice) ; and make it mandatory to get a grade• Additional review of selected morning exam topics;

department purchase professional FE review videos for AM sections

• Other suggestions?
