Finally, we’re not convinced that this isan appropriate learning outcome for first-year students. They are just being inducted into thescholarly community of engineers, and their information needs may be better served by lesstechnical articles.Student ConfidenceOn the pre- and post-tests, in addition to probing for students’ knowledge and experience withresearch concepts and tools, we asked one confidence question.

But in the past two years, with the support of a NSF-DRK-12 grant and cooperation with the education department, the PD training was extended tothree weeks.

With a fewexceptions, most respondents expressed their intent to forgo any future action with regard to theproposed curriculum models. For some, the reasons reflected a belief that there was not aconvincing case for the type of change embodied by these models. For example, regarding the 2-year co-curriculum model, one person cautioned that the model did “not align with our strategicplan or vision or needs or requests from employers.” Others feared the implications ofengineering technology being aligned too closely with engineering. “I discussed the concept withour faculty.

Studiesindicate that people in the U.S. are much more likely than the Japanese to believe that innateability (as opposed to effort) underlies children's success in mathematics12. Schoenfeld madetwo important observations based on the results of these studies7. “First, parents and students who believe ‘either you have it or you don't’ are much less likely to encourage students to work hard on mathematics than those who believe ‘you can do it if you try.’ Second, our nation's textbooks reflect our uniformly low expectations of students: ‘U.S. elementary textbooks introduce large numbers at a slower pace than do Japanese, Chinese

and reflect on the how it might work. Faraday’s law and examples ofsome applications are discussed. Students then examine the ring thrower from the point of viewof Lenz’s law. Next students are given a copper pipe and a very strong magnet that fits insidethe pipe. When the magnet is dropped inside the pipe it falls more slowly than a magnet fallingthrough a non-conducting pipe. This difference is to the magnetic field caused by the currentinduced in the pipe by the field of the falling magnet. Students are asked to explain the reasonfor the slower rate of falling. The principle is the same as the ring throwing device but this notrevealed to the students initially. Figures 9 and 10 are photographs of these two devices.Figure 11 shows a sample
