in CAD pedagogy, define designintent as a description of how an object is modeled and also how it should perform once it isaltered 15. They also assert that CAD software records the succession of features used to create amodel, which reflects the user’s opinion of the best approach to accomplish a specific task. Theyfurther state that design intent should be more comprehensive than shapes and sizes of features,but must encompass consideration of manufacturing methods and relationships between features.A student’s ability to accurately model an object correlates with their ability to visualize andassemble the objects cogently.Zhang and Luo state that CAD illustrates design intent through its history, features, parameters,and constraints16

students passed (n=14) with threshold raw scores of 95 orbetter. The raw scores for 86% (6/7) the students who did not pass fell within 10 correct answersof the passing score (85-94). One of the students who did not pass, drop the course. Another whodid not pass the exam took an incomplete for the course and eventually passed the certificationexam and the course. The fact this student passed the exam is not reflected in these data.As well, it did not appear pursuit of a Business Administration minor by the students influencedcertification exam performance. The proportion of students pursuing a Business Administrationminor who passed the exam was basically the same as the proportion of students pursuing someother minor or that were not pursuing a

technology subjects that were comparable to the classicalacademic subjects challenged the nature of technical education in Ireland [15]. As a resulttechnology subjects were redeveloped to reflect more academic constructs. This is evident inthe introduction of senior cycle Technical Drawing as a state examinable subject in 1969.This syllabus attempted to make the subject more academic and as a result concepts andtopics were deliberately addressed in more abstract terms in an effort to distance itself fromthe applied, vocational nature of its origins [16]. However, recent years have seen a shift infocus for technology education, and in particular graphical education, within the Irish highschool level system. Design and Communication Graphics (DCG) was

Specifically, the researcherswanted to see if replacing the PSVT-VOR with one that uses pictures of everyday objects(i.e. Pictorial VRT), that by common everyday associations students might do betterusing images on visual-based tests. But, as the findings indicate it is just the opposite,students that participated in this study did statistically better using the traditionalgeometry or isometric drawing version of the same test that was repurposed witheveryday images.Based on the

information systems as a new informationvisualization subdomain that complements the focus on analytic tasks, and also providesanalytics, awareness, social, and reflective sights.A Collaborative Design Process The mini-challenge of “Situation Awareness Display Design” started in the beginning ofMay and its submission deadline was on July 8, 2013. We organized a team with two ComputerGraphics Technology (CGT) students, three Interaction Design (IXD) students and two faculties.The seven team members started to actively work on these challenges from the middle of May.The two faculties, one come from CGT, one come from IXD, served in multiple roles –supervisor, teacher, collaborator, and researcher to study the collaboration process.

I am also going to start using chamfers and rounds as a feature.” • “In the future, I will try not to group up different features in a mirror so that I could change the part if necessary.” • “After seeing how useful mirror is in the past few labs, I will certainly employ more use of that feature.”A few reflected on the situational aspects of modeling strategy: “I would certainly use differentmodeling strategies depending on the intended future of a particular part file.” Some of thesecomments may reflect the students’ inexperience with changing models, as it was observed thatmany students immediately opened the sketches to make simple dimensional changes rather

respond to conceptual questions13. Students were given either an incomplete or incorrectsolution, they then formed pairs, discussed their answers, and presented their understanding byusing an interactive SMART Podium to the whole class. The quick feedback greatly aided theinstructor in helping students address a given misconception. Peer instruction promoted thecollaboration, conceptual understanding, and problem-solving skills. Concept testIn this method, the lectures were punctuated by multiple-choice conceptual questions to teststudent understanding of the material. Often the distracters (incorrect responses) reflect commonstudent misconceptions14. Previous research has found that students attention spans duringlectures is typically fifteen
