Teacher Education (ITTE) at the University of Limerick (Ireland) and NorthCarolina State University (USA). An in-depth review of the nature and purpose of graphicsbetween both institutions is presented. A number of pertinent questions relating to thedefinition of being graphically capable and curriculum planning are presented. This paperwill be of particular interest to academics who teach Engineering Design Graphics, highschool teachers and engineers.

individual organization. Collaboration suggests a more durableand pervasive relationship, and the authority is determined by the collaborative structure. Weaim to establish a true collaborative relationship in this design competition task. To judge thecollaboration type of design, identifying its mission, authority, and relationship is important.Kvan [26] suggested that collaboration is also episodic and cyclical. Collaborators interactperiodically, but they work independently and parallel during portions of the design. Kvan’smodel is demonstrated by Fig. 2. There are generally four stages in an iterative cycle: meta-planning, negotiation, expert work, and evaluation

. The objective was to ensure that all design technology graduates possessedan understanding of technology management practices in the areas of production, planning, andcontrol; quality control; safety; and management specifically. The goal was to improve the levelof understanding of technology management among graduating design technology graduates.An initial study of the students’ performance was completed in the spring of 20121. In this study,the performance of design technology majors on their understanding of technology managementwas ascertained. The criterion for success included (a) a 91% pass rate for all who sat for thecertification exam and (b) for those who did not pass the exam, the number of correctly answeredexam items will fall

The grade earned by students was either Satisfactory/Unsatisfactory.During Autumn 2012, there were four sections of ENGR 1180 offered. The students sat four to atable where a computer was available to each student at the table. The workbook utilized wasDeveloping Spatial Thinking Workbook by Sheryl Sorby and software by Anne FrancesWysocki.8 A Tactile Modeling Set (linking cubes shown in Figure 1) were provided to studentsto build the objects based on a given coded plans (Figure 2) detailed in the workbook. Thesecolorful linking cubes were available during class and for students to take

They further define the components of CAD expertise to include thegeneral categories of the part modeling task, procedural 3D CAD knowledge, strategic 3D CADknowledge, declarative 3D CAD knowledge, graphical and visualization capability, modelingdeconstruction capability, and metacognitive processes 19.Evaluating CAD ModelsStudies involving the evaluation of CAD models have been quite diverse.

an important aspect in the development ofmodeling strategies.Barnes et al.24 suggests that many of the exercises presented to students are in the form of“elegant solutions” which present essentially one single obvious modeling approach. Fortunately,even very simple parts such as those presented in standard graphics texts can be modeled usingdifferent strategies. In planning a part model, the designer must decompose or “featurize” thepart to be created in the solid modeling system. Two common strategies for modeling simpleparts involve decomposition into features based on either additive or subtractive approaches.30Metrics for Evaluating Solid Model Part ComplexityIt is important to choose parts for CAD instruction that present increasing

resources16. Wanget al17 develops a VA system to help bridge managers analyze bridges and plan maintenances.Wong et al18 created a visualization system called GreenGrid to examine power systeminformation through semantic encoding, multilevel graph visualization, and force-directedlayout. Jigsaw19 and CZsaw20 enable users to make sense of a large collection of text. They offera collection of visualizations to detect the connection among alternatives. With document view,scatter-plot view, history view, and dependency graph, these visualizations can help usersexamine the connection between entities and support analytical strategies. Such VA systemshave been widely adopted in many domains. But it is still rare to see the application of VA onPLM.Possible
