Land and Water Resource Engineering 2. Biological EngineeringBackgroundLand and Water Resource Engineering builds on a traditional strength in AgriculturalEngineering. This limited specialization focuses on the stewardship of our land and waterresource. Issues are soil conservation, water quality, non-point source pollution, precisionfarming, decision support

motivational tools served as means to create a betterteaching and learning environment in the classroom and in the laboratory. The response of thestudents was constantly monitored. The results show that the various activities strategicallyplanned to motivate the students to become active learners and to situate them in the context ofthe practice of Civil Engineering had a positive effect on several aspects, including theirperception the of the significance of the knowledge being acquired, of the reality of their futureprofession and of the importance of the tools they might need. Another significant increaserelates to the perception the students ended up with of their capacity to transfer the knowledgeacquired to other situations.1. General

The design is a trimaran-type vessel with a streamline main hull andpontoons for stability. The original reasons for implementing this concept included reducedresistance, adequate stability, ease of constructibility, sufficient internal volume to accommodatea propulsion system, and adequate deck area to support a series of solar cells (figure 1

last few years, a significant effort has been taken to restructure the system of study atthe Faculty. Students admitted before 1994 have followed the traditional pattern of university-level engineering education in Poland, i.e., they have pursued a five-year program leading to adegree equivalent to the Master of Science (Master of Engineering) in the selected field ofengineering3,4. With the beginning of the academic year 1994/95, a new system of study wasintroduced. In what follows, we briefly describe those features of the system that mostsignificantly contribute to its flexibility.

Examples of these for the design ofstepper motor (SM) applications are: 1) the level of the technical progress in the particularapplication, 2) manufacturing technology requirements, 3) safety and environmental factors, 4)equipment and machines used in the process, 5) economic considerations.

each problem requires that the student-generated part beexamined term by term. In this case, evaluating the function for x=1 would detect the error whencompared with a hand calculation (with presumably correct syntax). However, the instructorprefers never to use 1.0, but at least use 1.1, etc., because if the correct term is 2x and one usex=1, the same answer is obtained if the term is 2x or 2. These subtle distinctions and strategiesare important to learn.The next part of the computer tools one needs to learn is when to use which tool. It is easy tosolve a single nonlinear algebraic equation in both MATLAB and EXCEL. Sets of nonlinearequations can be solved in both by developing an optimization function which is to be mini-mized, giving the

Engineers?MIT's first Dean for Undergraduate Education, the late Margaret MacVicar, once noted [1] thatthe challenge for educators with respect to integration of engineering, humanities and socialsciences is to bring about: “...a true educational partnership among the technical, arts, social andhumanistic disciplines so that on some level students see the interrelationships between scienceand technology on the one hand, and societal, political, and ethical forces on the other.”One approach to exploring such interrelationships is through the STS courses and programs thathave sprung up over the past quarter century. Indeed, the critical reflection on the interactionsamong engineering, humanities and social sciences typically found in successful STS

Introduction “The reasonable man adapts himself to the world; the unreasonable man persists to adapt the world to himself. Therefore, all progress depends on the unreasonable.”George Bernard Shaw Given that the goal of research is to induce progress by advancing the state-of-the-art,Shaw’s comment would suggest that there is no straightforward way to teach someone how tobecome a good researcher. If Shaw is correct, it would seem that the job of a teacher of futureresearchers is to somehow teach a sort of “controlled unreasonableness.” While the
