During a lecture, students take class notesand ask questions. Such a pattern obviously has some problems. For instance, the one-hourlecture may be too short to solve student’s problems or to answer student’s questions. Theavailability or accessibility of an instructor after lecture hours is one of important key issues inteaching of engineering courses. Today, with help of high technology of telecommunication, theteaching of engineering courses can be improved greatly with many ways. Teachingengineering courses through the Internet is one of them (1, 2, 3, 4, 5 and 6).The Internet is a

This exercise will utilize the methodsactually used by a project team from a Biomedical Instrumentation Corporation in which both engineersand technicians from various disciplines participated.The steps involved will consist of the following: 1. Determine the nature of the problem and create specifications. 2. Brainstorming to compile a list of possible solutions. 3. Select three best possible solutions. 4. Sketch one of the solutions. 5. Suggest ways to test solutions.This method can be used in any number of technology courses and will help the student preparefor problem solving and working in a team environment.IntroductionThe following is a method of problem solving used by project teams in industry.

The project assignments include general guidelines only and encouragecreativity in both functionality and design.

German investigations have demonstrated the beneficial results of teaching formaldesign methodology.1. IntroductionDesigning and design theories, methodologies and methods have been under intensiveinvestigation since about 1960 (compare chapter 3 in 1). In these investigations, several distincttrends can be found.One, the artistic trend, claims that designing needs creativity (and only creativity?), thatcreativity is an inborn trait of particular humans, and that inspiration comes from an unknownsource. In this way, the designer is unique, talented and privileged. Designing, in the extreme,cannot be taught or learned. Only a
