Engineering iimdamentals and theoretical and analytical concepts seem to sink in better whenlinked to applications and engineering design methodologies. The challenge is to emphasize design withoutcompromising basic principles. “The crux of the design process is in creating a satisfactory solution to a need it is what engineering isall about” [1]. Design is perceived to be “creative problem solving” which requires both creative and criticalthinking skills. Conwell, et. al. [1], considered those two skills to be synergistic. The development of one skillaids in the development of the other. Developing these skills requires creative approaches to: (1

Hav-ing students wrestle with problems in realistic contexts will produce new insights thatcan provide abundant and unanticipated rewards for students and instructor. Cases can be used (1) as vignettes of engineering history and experience, (2) as amp-lification or application of lecture material, (3) for introducing new or ancillary tech-nology, (4) as problem sources, (5) as bases for design projects, (6) as bases for labora-tory exercises, and (7) as general learning and educational resources.

- octane. The mole fraction of propylene is 0.515. When recovery of the propylene is desired, it passes through a series of heat exchangers and an adiabatic flash valve to lower the pressure and change the temperature. The final product is 99 mole% propylene vapor at 30 psia and 60°F. The n-octane is returned to storage. A heat exchange network for a propylene storage facility is shown in figure 1 (1). The feed stream, which contains propylene dissolved n-octane, is preheated in the first heat exchanger, H-1, to recover heat by partially condensing a recycled stream consisting of propylene and n-octane. This feed mixture is further heated to its bubble point in a second heat exchanger, H-2, using high pressure steam

Interior walls were typicallyconstructed of 3 1/2” metal studs with a double layer of gypsum board on each side. Exterior walls were ofbrick with 6“ metal stud back-up, an air space and insulation.The roof structure of the addition was also handled differently than the original building.

Our plans for support of the Robotic Soflware Systems course involved the acquisition of “smart” roboticsystems, that is, we anticipated acquiring robots that have on-board microprocessor systems and the ability to becontrolled from a teaching pendant. These characteristics would provide for quick “start-up” time for students tobecome familiar with the system by learning to guide, control, and store trajectory programs for the robotsystem’s manipulator arm, thus, learning the fundamentals of this new type of 1/0 system prior to delving intoinstrumentation

Specifically, the senior project course for NJIT’s Electrical Engineering Technology (EET) program emphasizes two aspects of project development: 1. project design and 2. the development process associated with design and implementation. Although achieving a working model of a project is considered of prime importance, equal importance is given to the development process used to design and implement a project.

The primary goal of the Engineering Major at Hope College is to prepare students for direct entryinto graduate school in the engineering speciality of their choice. To enable the students to haveadequate preparation in a four year program in which the engineering major must conform to thestandards for all other liberal arts majors, significant curricular choices have been made. Guidance inthese choices have been provided through: 1) advice from a consulting group of academic engineers,2) visits to traditional and non-traditional engineering schools, and 3) discussion with graduate schoolfaculty members as to the preparation really needed for graduate

the form of classroom lectures is still the most prevalent methodat institutions of higher learning. While classroom lectures are an important component of teaching, theireffectiveness, as far as student’s comprehension of the subject is concerned, may be less than desirable. Ofparticular concern is the way engineering courses are typically taught — based primarily on lectures. In-depthunderstanding of the physical concepts and methods of analysis discussed in an engineering course, especially atthe senior-level and beyond, requires an enhanced method of instruction that gives full consideration tovariation in students’ learning styles and thinking preferences. 1 However, tailoring of classroom lectures alone,toward this objective, would

conventional technological options and thinking. The new designs from ecological engineering are generally less expensive or have lower energy intensity than traditional approaches and they often result in more environmentally sound systems or decisions. These qualities of ecological engineering designs (less economic cost and greater environmental value) are bringing more attention to the discipline from decision makers, who seek to implement the designs, and from educators, who must decide how to incorporate the information into university curricula. In this paper the efforts at the University of Maryland towards developing an ecological engineering curriculum are described. There are two purposes of the paper: 1) we
