and lectures and tends to be information rich. Step 2 can be complex and abstract as it may require new language, concepts, paradigms, and ideas. Retention is most effectively achieved by making connections to students’ prior knowledge and requires use of both lower and high level cognitive levels. 3. Practice under Constrained Conditions. This step transfers the new information gained in Step 2 to practice under highly constrained conditions. This step requires active learning principles. The classical approach in engineering education is the short-answer homework problem, but discussions, laboratories and group problem solving are also successful.

middle school teachers (teaching Biology and Math) were selected toparticipate in research dealing with tissue engineering. Teachers worked for six weeks (fourdays a week) within the research laboratory on formation of porous structures usingbiodegradable polymers. Teachers were exposed to the technique of forming porous structuresusing chitosan and gelatin solution in various shapes using the apparatus available in thelaboratory. A low cost freeze drying system that is safe for operation by sixth grade students wasdeveloped. The overall cost of performing the experiment is also significantly cheap and lesstime consuming.An envisioned project for the current academic year under implementation in the sixth grade isfreeze drying chitosan-gelatin
undergraduate laboratory experience. In 2010 we addedthree completely new experiments to the course; these activities (a student-directedexperiment with thermoelectricity, a pump performance module, and a fluid flowexperiment of unparalleled flexibility) were designed to encourage exploration, to appealto students with different learning styles, and to promote physical contact between thestudent and the underlying phenomena. This paper describes our initial experiences with,student reaction to, and our assessment of, these changes to the laboratory course.Introduction The childhood environment for the previous generation of engineers was verydifferent.

-based educational tools have been developed (15-22) for specific areas, such asprocess control, laboratory experimentation, thermodynamics, and process design. To obtainrealistic solutions for multiphysics problems in two or three spatial dimensions, one must usemore advanced approaches for solving coupled systems, which are usually based on the finiteelement method. This requires a good understanding of the basic theory behind the method, asolid knowledge of linear algebra, and a host of other supporting techniques that are related todiscretization, mesh generation, nonlinear equation solvers, numerical stability, to name a few,along with computer science skills for implementation. These skills are often beyond the scopeof the typical
important aspect of this project because traditionally, the chemical engineeringcurriculum stresses the scaling up of laboratory chemical reactions to larger chemical processingunit operations and often students enter the class with the bias that chemical engineering means“scaling up”. Particularly as studies of biochemical reactions in microbiological systems, suchas proteomics or in microfabricated devices as in the body-on-a-chip described here, are soprevalent in the chemical engineering research literature, it is important that students are exposedto the possibilities and advantages for scaling down chemical processes and the related careerchoices.Student appreciation of the significance of scale down on several levels (efficiency, safety

The course emphasizes programming and coupling math concepts with measurements and data. The second required, 1 credit course is Introduction to Engineering Modeling. This is an introduction to mathematical modeling of physical and chemical systems; verification of mathematical models by experiment; development and interpretation of engineering drawings, process flow diagrams (PFDs), and piping and instrumentation diagrams (P&IDs); use of a drawing program, such as Visiotec; and an introduction to the process simulator AspenPlus.
