ofsecond-grade students met with the project team to discuss robots. During this session, studentswere introduced to: (a) industrial robots and the tasks they often perform, (b) task planning andcommunication with robots (programming concepts), and (c) robotics-related jobs and theimportance of studying math and science in school. Several short video segments (2-5 minuteseach) showing industrial robots performing interesting tasks were also shown to the studentsduring this session.After the initial 40 minute session, the research team met with each of the second-grade classesseparately for a robot programming activity. The goal of this activity was to engage the childrenin a fun, hands-on activity that would introduce them to the concepts of task

appropriate equations and variables to solve problems from written material.  Transitivity and reversibility. Students are able to algebraically manipulate equations and to discern relationships between variables knowing that if A is taller than B, and B is taller than C, then A must be taller than C and that if Z = X+Y then Y=Z-X.  Conservation. Students can understand that certain characteristics can be conserved even in different forms so that logical relationships can be formulated. The content in classes on material and energy balances rely fundamentally on such conservation principles – although conservation of energy is much more complex for students who use concrete reasoning.

The proposedcenter’s faculty members will focus on linking the student teams with the resources of the IncUBator. Students maycreate their own company or work with existing companies. In so doing, the university will: a) create the goals,roles, procedures, and relationships that must be developed for students to successfully work with the IncUBator andits related companies and b) create models of success that will demonstrate to area companies the advantages ofworking with graduate student E-teams.

At that time,assessment data and observations indicated that MET students in the capstone courses oftenlacked experience in some fundamental engineering skills – specifically a.) Students lacked the opportunity to exercise the classroom topics of correctly interpreting engineering drawing details such as dimensional tolerance and surface finish callouts, material references. b.) Students had no opportunity to plan and execute the manufacture of multiple components from design drawings that had been created by another individual. c.) Students had little experience with standard industry documentation

To do this, we created two grading silos: (a) Average performing students,and (b) Low performing students. This was done to eliminate the bias that might result fromcomparing high performing teams from one year to low performing teams in another. We basedour silos’ grade range on the University’s transcript guide and the course’s historical average. Apresentation was deemed to belong to the average performing silo if it received a B (between73% and 76%).

past the middle of the semester, there wasnot enough time to accomplish all three tasks, and none of the submitted designs met the full setof design criteria. If the project had been introduced early in the semester as a required part ofthe curriculum, the students earning an A or B for the course would have submitted designswhich would have been more likely to meet the criteria.Freshman design projects are necessarily a gamble; students are asked to design a structure ormachine before taking any mechanical design courses, so the results are often strong in conceptbut weak in technical soundness. Clearly, juniors or seniors would have developed betterdesigns. However, by exposing freshmen to a design problem early in their academic careers
