Learned and ConclusionsThere were quite a few lessons learned by the instructor from this PBL experiment:1) The hardest part about the experiment was, in the first place, picking a good PBL problem thatwas relevant to the class material at hand. Some of the criteria that the author used in selecting aproblem were: a) the design has to emphasize, or at least force the use of, concepts and equationslearned in the classroom, b) the possible solution designs should be relatively simple to make orbuild, not costly in dollar amount, and not very time consuming.2) The second thing learned was that the implementation of PBL takes a significant portion ofthe instructor’s time.3) The instructor needs to alert students to verify assumptions made in their

. ConclusionLearning science and engineering concepts should not be a passive process - to understand, astudent must do. Learning should be a hands-on experience. American Chemical SocietyPriestley Medalist Harry B. Gray stated this quite vigorously “I ... would ... do away withintroductory ... lectures completely, and build a first-year course entirely around experiments.’’We believe that these workshops are good examples of the types of active learning exercises thatcan be adapted by others to fit their teaching goals. We would be happy help others implementsimilar programs. Proceedings of the 2003 ASEE Gulf-Southwest Annual Conference The University of Texas at Arlington

station (model PM 5; 2000 x magnification), a pair of Karl Suss RFmicroprobes (model PH 150), and the set of Pragmatic Instruments MEMS Driver Systemarbitrary waveform generators (model 2414A).The microengines are based on the addition of electrothermal actuators in parallel in order toharness a greater force. When two sets of thermal actuators are used in conjunction, one toengage a pawl and another to move a linear mechanical slider, we can achieve continuous linearmotion. The pawl is activated first, driving the translator down and forcing a mesh between thesets of gear teeth (Fig. 2 (B)). While the gear teeth sets are meshed, the translator is activatedpushing the shuttle (Fig. 2 (C)). Before the translator finishes its cycle, the pawl is

The eminent AI guru is notorious for his difficult tests, so the students have begged him repeatedly for a multiple choice quiz. Finally, with a devious smile, he agrees. On the next test, he asks the first question in Swahili, which no one can read. However, the following answer choices are in English.
