However, it is not sufficient to simply assign a “pre-packaged” hands-on activity. Tomaximize the educational benefits of the project, students must be involved in all stages includingproject selection and scheduling. Fosnot 3 observes that learning occurs “through engagement inproblem posing as well as problem solving, inference making and investigating, resolving ofcontradictions, and reflecting.” Therefore, a complete educational experience would require studentinvolvement in all phases of the project.

semester, using a scheme developed by Brown (1995). Team members hand in individual assessments of one another’s level of effort and teamwork on an 11-point verbal scale ranging from “excellent” to “no-show.” They are instructed to consider how consistently and how well their teammates completed assigned tasks, prepared for team meetings, showed up for team meetings, fulfilled their team roles (coordinator, recorder, etc.), and helped other team members. They are also cautioned that the ratings should not reflect intelligence or technical competence. The ratings are converted to numbers (100, 87.5, 75,…,0). The ratio of an individual’s average rating to the overall team rating is multiplied by the average team report

One possible explanation of this fact isthat in the countries where such systems were developed and are used, the political and economicsystems are quite stable, i.e., the external conditions of functioning of academic institutions donot change so rapidly.We believe however that, for a country whose higher education system is strongly affected by afast transformation of the political and economic system, the criteria that reflect the dynamics ofchanges made at the academic institution in the past and the preparation of the institution forfuture changes, such as those proposed in Section 3, are good indicators of education quality.Although

INTRODUCTION In the US, as in most other countries, the field of engineering has been traditionallyoccupied by men. However, demographic trends indicate that by the year 2000 sixty-eightpercent of the new entrants into the US labor force will be women and minorities.1 Led bygovernment and industry, this reality has manifested itself in a national movement to encourageeducational institutions to increase the numbers of women and minorities pursuing careers inengineering.2 Statistics compiled over the last two decades reflect the status of women in

At least twosensor applications are necessary: one to help navigate the robot through the mazewithout colliding with the walls, and the second to detect the candle light.

Also note that thislist does not include 8 of the 18 items because it was decided not to include items where thelargest number of respondents ranked the items either 1 or 2 (i.e. low in importance).

This is not the case in the CSU or at Cal Poly.As structured, GEB at Cal Poly is anachronistic. It currently reflects a medieval/classical focus on English, historyand philosophy that addresses only a portion of what the truly educated college graduate should know. It does notmeaningfully address additions to the central body of human knowledge produced during the scientific revolution,and is absolutely mute with respect to technology.

that differences in achievement andparticipation parallel the differences in belief and attitude (Boekaerts, 1994). As compared totheir peers of equal skill, students with higher expectations, self-confidence, and good controlperform better in mathematics. Positive beliefs about their problem solving ability turn mathproblems into interesting activities worthy of their effort. Students with unfavorable personalbeliefs view math problems as threatening and non-interesting experiences. These beliefs arecoupled to low math performance (Seegers and Boekaerts, 1995). In addition, Boekaerts (1994)hypothesizes that ambiguous math problems requiring re-framing, modeling, experimentation,and/or reflection can promote insecurities and disturbed task

Also the OSU study found that the highest ranked technicalskills were in the computer and graphics area2. However, our results put a higher emphasis uponCAD knowledge and a lower emphasis upon computer programming than the OSU study. Thischange may simply reflect the changes in the workplace since their study was undertaken in1992.

Our use of this algorithm, which isbased in the field of combinatorial optimization, reflects properties of Boltzman machines - a neural networkcharacterized by massive parallelism.We will demonstrate two implementations of this algorithm in simulated annealing. Each of the implementationsdepends upon a neighborhood structure and a transition mechanism. In the first implementation our neighborhoodstructure is a linear transformation of the vector space of all configurations and the transition probability isdeterministic. In this case, we will use techniques from character theory of finite groups to analyze simulatedannealing. In the second implementation, a special case of which includes the first implementation

However,many respondents commented that this was not the case in technology management.The results from this study as well as some of the comments made by the respondents point to afew areas of opportunities. These include:• The development of more technology management case studies should be encouraged. A large number of courses use case studies and a number of respondents commented that it was difficult to find appropriate case studies that had sufficient technical content.• There is no common usage of textbooks. This might reflect a shortage of appropriate textbooks. It was noted however, that it might be difficult to develop textbooks that satisfy the diverse demand that exists.• There
