The second assessment consisted of anevaluation of the final projects, which were a collection of five sketches with different views ofan engineered product. Evaluations of the pre- and post-test drawings and the final projects byoutside reviewers and positive observations by engineering faculty suggest that this course hasthe potential to improve students’ ability to sketch objects.This paper discusses details of the course, provides examples of student sketches, and presentsresults of outside reviewer assessments.

engineering graphics courses still lacked certain skills andunderstanding when creating their design models and working drawings. For examples, manystudents didn’t understand the difference between working drawings and the corresponding 3Dobjects, and they had difficulty in creating sheet metal components and gears. This was an on-going project which started in fall 2012. Some details concerning the implementation ofintradepartmental collaborative work including assessment was discussed in this paper, morewill be discussed in future papers.1.

Among the several competencies desired by the job market,engineers with these skills are highly in demand. Therefore, like most engineering programs 2 - 4,our manufacturing engineering program at Virginia State University places a great emphasis onhands-on activities in part design and product assembly competencies in its curriculum.Manufacturing engineering students develop skills for the various elements of the design processthrough the curriculum, culminating in a

It is believed that authenticity, meaningfulness and completeness of the assignmentsincrease students’ involvement and motivation for success.1. IntroductionDesign is best practiced and learnt by doing1. Thus, the course utilizes project based approachwith authentic tasks to integrate previous knowledge and skills. In order for an activity or task tobe considered as “authentic” it should be studied in an “enhanced educational setting withincreased motivation and enthusiasm.2” In the literature3 four characteristics of authentic tasksare listed as: “(1) real-world problems that engage learners in the work of

students’ approaches to generating, maintaining and communicating visual-mental imagesThe ability to synthesise and manipulate graphical information is a core cognitive aptitude.Visual-mental images are crucial to problem solving and design processes. The ability tomanipulate and communicate perceptual and conceptual information graphically often leadsto creative discovery and aids mental synthesis. Graphical education in Ireland supports thedevelopment of these ‘concept driven competencies’ through the study of plane anddescriptive geometry and through engagement with design problems 1.Previous research by Delahunty et al. 2 has highlighted a worrying issue of mechanisticconditioning within graphical education in Ireland.

In addition to describing the general assessment method, this paperdescribes a specific course to explain the assessment process. We selected the first year computergraphics course to satisfy the student outcome (f) of the Associate of Science (AS) degree. Thestudent outcome (f) places significant emphasis on written, oral, and graphical communication.Though the assessment method is general, this paper

A demographic instrument was employed to gatherdata that assisted in classifying students as being at-risk of leaving college or not at-risk. Theresearchers used the Fisher exact test to analyze the collected data. The Fisher exact test is mostcommonly applied to evaluation of a hypothesis with data framed in a 2x2 contingency tablewhere chi-square assumptions are not individually met.1 The null hypotheses are evaluatedbased on the probability of determining a collection of “observed frequencies even moreextreme” than the set summarized in the contingency

In this paper, we offer preliminary evidence on the comparison of tactile to virtuallearning as perceived by our students and share instructional issues that students feel either helpor hinder their ability to learn.1 IntroductionGiven that there are numerous ways to define engineering design, it follows that there are manypedagogical approaches to teaching design.

Students were administered thePSVT:R and the MCT and were then given an assembly drawing and asked to model as many ofthe seven parts as possible during a 110 minute class period. The parts in the assembly ranged incomplexity from a ball to a valve body. Students were given a ruler to measure parts on the B-size drawing and determine sizes of features based on the given scale (2:1). Relationships wereexamined between the PSVT:R, MCT, modeling activity, final project and the final exam.
