They spent the full time period generating solutions and werenotified when there was five minutes remaining. The solutions were analyzed using the ideationmetrics: quantity of non-redundant ideas, quality, novelty, and variety, which are detailed in thenext section.

The statement “overall I rate this course asexcellent” received an average 4.6 on the same scale. Student comments reflect theirsense that the course was well designed “The experiments we did in class were a greatway to see the theory we discussed come true”; “It was a great way to connect what wewere learning to the everyday life of cooking.”. The main criticism for the course wasthat it had no dedicated kitchen-laboratory space

Digital Logic Circuit lab with TTL chips on traditional breadboardThe lab on breadboard with logic gates (all hardware based labs) is an outstanding method togive the students very basic understanding of the digital logics. However, as the circuits grew,we noticed two problems every year, viz: a) students get bored with multiple wire connectionsand get frustrated when circuit did not work, and b) it was never possible to complete all the labsprescribed in the syllabus.To alleviate these two potential problems, we adopted two new methods in the lab.

The morechallenging a question, the better; like the more that they can think like out of the box, thebetter.” Michael from HBCU1 even faced some doubt, “…I thought about changing my majorseveral times.

Rotating Principal Stresses In A Materials Science CourseABSTRACTThis work constitutes a laboratory component of a junior level materials science course andillustrates the importance of rotating principal stresses in the design of components such as theautomotive crankshaft. The activity is centered on Mohr’s circle for biaxial stress situationsinvolving time varying normal and shear stresses. A number of dynamic situations have beenconsidered, namely. (a) sinusoidally varying normal and shear stresses that are in phase, (b)sinusoidally varying normal and shear stresses that are 90° out of phase, (c) constant normalstress and sinusoidally varying shear stress, and (d) sinusoidally varying normal stress andconstant
