Summary of Past Performance
** Except for 1995 (3 people), 1996 (16) and 2001(24), UTK/ChE has consistently performed below both state and national averages
** Of those who don’t pass, they miss only by 1 to 9 points (70 is passing) --> 1 to 7 AM problems, or 1 to 3.5 PM problems

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?
