The SS1 sessions provided a supportiveenvironment for students to work together on homework and group projects while building asense of community and shared success. The SS2 sessions were one hour long and included theentire class, along with the SS1 Leaders. These sessions included workshops on studytechniques, test taking, physics lab

If students have a weak background and/or a low confidence with IT, then ITintegration should be different from a group of students whose background and confidence ishigher. The challenge was finding a consistent, quantifiable measure. To accomplish this, wedeveloped an IT impact analysis factor (IAF), which is a weighted average comprised of thestudents

Thereason for this low rating is unknown, but, in any case, only a very small minority of the studentsfelt this way.Planned Future WorkThree of the four described experiments (i. e., the electric circuit, the cooling of a cylinder, andthe cantilever beam experiments) are portable and can be moved via carts into the computer lab.Plans are to make a small-scale, portable version of the orifice flow meter experiment that canalso be transported into the computer lab. It is also planned to modify the experiments so thatexperimental results can be projected in real-time on the computer lab screen.ConclusionsThis paper discusses

It is most practical to use a procedure such as the Geyser Greenhouse or Hyunh & Feldt to accommodate for violation of compound symmetry/sphercity. 5. Tukey’s test of additivity indicates whether there is an interaction term or residual additivity. If there is an interaction term, power goes down since the type II error for factor A increases. 6. In addition to checking the above assumptions, Multiple Comparison Procedures may be used. The MCPs selected depend on whether spericity has been met. However, they do not apply to the research questions in this project, so they are not run.I hope to learn whether student attitudes improved

reforming our engineering educational system has been made. The challenge hasbeen how to make the needed change happen in the curriculum. New practices in teaching suchas inquiry- and project-based learning, experiential learning, and service learning10 as a way forlearning non-technical skills are now common.New changes in curricula and/or extra requirements from students can put pressure on thealready-packed engineering curriculum. The reform effort of the department of civil andenvironmental engineering at University of Vermont, described above, developed a series ofthree system courses to implement the reform. Students were displeased about the organizationof the newly designed systems courses.11 Some too-ambitious curriculum reform efforts
