CAEE-201 Spring AY2013-14 : Take-Home Assessment

Some of you may wish to know how the class performed on the final Take Home Assessment. Here are some comments

I graded all the essay questions myself – almost everyone was careful and received full credit
I reviewed the “item analysis” provided by BbLearn. It looks at the performance on each question to see if there problems because they were poorly written or possibly required material that was not presented in class.
- As a result of that review I decided to add 8.7 points to each person’s raw score to make allowance for possible lack of clarity, although I found no questions that I felt were wrongly stated.
- The result of this increase in the exam is reflected in the column –CAEE-201 TakeHomeAdj

Learning after Graduation – It’s almost certain that you’re going to need to go on learning throughout your career as an engineer. Many of you chose answers that indicated your thought there wouldn’t be much later learning.
Heat Transfer Calculation – this was the same basic question as in Lab #1
Nested IF Function – This was admittedly a difficult question, but it was directly based on the hydrology lab. Learning to use this kind of logic will almost certainly be beneficial in your engineering career.
Gas Concentrations – A key result of the IAQ lab was that you cannot have all things – low ozone and low CO2 merely by ventilating.
Revit Type – Revit is BIM software, not a sketching or drafting tool. When I Googled the word Revit the first entry stated that as I did in class.
EER – EER is a ratio of BTU/Watt-Hour – It’s a measure of efficiency of an air conditioning system. it is NOT dimensionless as it is used.
Member Weight Calculation – It’s surprising that a number had difficulty with this one. You needed to calculate the volume and multiply by the density, being sure to watch the units of volume to work in either in^3 or ft^3.

I covered this in a separate post
