Page 14.422.1© American Society for Engineering Education, 2009 Design Visualization and Service Learning: Using Photorealistic Computer Rendering to Support a Third-World Community Development ProjectIntroductionComputer rendering has evolved to a point where the ability to generate photorealistic images isa standard feature in most CAD applications. The objective of photorealistic rendering is to“generate images from computer modeled scenes with an image quality as close to real life aspossible” [1]. The origins of computer rendering are rooted in technological developments thatare nearly a half-century old. However, more recent developments in photorealistic renderingapplications and in the

Frequently cited objectives address ABET outcomes such as 3(k) “an abilityto use the techniques, skills, and modern engineering tools necessary for engineering practice.”9 Inlower level introductory engineering courses, these objectives include familiarizing students withnew technologies and using the prototype as a motivator or reward to encourage studentengagement6-8.

addition, many include a Conceive-Design-Implement-Operate (CDIO)1 or similar type of project experience. It is difficult to fit all this content into aone-semester course. Often student teams do a good job with the analysis and fabrication of thephysical prototypes of their projects; however, their final project reports are usually of lowerquality. This seems to be especially true of their working drawings. The students have coveredthis material and have submitted related drawings assignments successfully earlier in thesemester, so the challenge is to find ways to get them to review this material on their own beforeturning in their reports without taking up additional class time. Could an online review andassessment tool be effective in

Retention into thesophomore year was also higher for students participating in pair programming.1. IntroductionPair programming, an ingredient in extreme programming, has been used extensively in softwaredevelopment in industry, and has been used experimentally in computer programming basedcourses for engineering students. This paper describes the introduction of pair programming intothe course EGR 140 Engineering Graphics at Oral Roberts University. The course uses the CADsoftware SolidWorks, and emphasizes solid modeling. Pair programming was introduced in adesign project and several smaller special

andnatural affinity between U.S. higher education and its ancestral nations overseas. In addition tocountless research projects and other cooperative endeavors, many U.S. schools have maintainedhealthy exchange programs and study-abroad initiatives for the majority of their existence.2These types of programs enjoyed somewhat of a renaissance following World War II, as theexperience of that event brought into light the need for the U.S. and its citizens to adopt a globalmindset. As a result, a variety of sponsored educational initiatives were implemented such as the1946 Fulbright Act, which provided legislation to promote funding for international educationand research through the sale of surplus military equipment.1 The Cold War served to

Problemsolving, creative thinking and practical skills are integrated into a unique set ofsubjects with a common philosophy grounded in design. “Designing is a demandingand complex problem solving activity of great economic importance and sketchinghas an integral part in this” 1. A central focus is placed on sketching and the influencethat technological education has in the development of pupils’ ability to sketch. Theimportance of sketching will be explored under three facets which are cognitiveimplications, educational significance and the economic benefits.Educational SignificanceThe value of freehand drawing in technology education cannot be underestimated.

The Likert scale utilized a range from one (1)“Strongly Agree” to five (5) “Strongly Disagree.” The graphics version, known as the “NorthCarolina Learning Attitudes about Graphics Education Survey” (NCLAGES), consists of 43statements as well as demographic questions. The simple word exchanges, from “science” to“graphics” and “graphics education,” made the instrument appropriate for this investigation andwas easily articulated over to the new content area for assessment.The second instrument examined motivation.

The review panel also participated as a test-piloting group toensure the instrument being used for a given round was reader-friendly and easily understood(Martino, 9). The instrument for Round I of the modified Delphi method was developed frominformation found in the review of literature. Examples of quality indicators were establishedand placed in a survey instrument (see Table 1). Once the review panel approved the instrument,the expert panel was given access to the instrument on the web through a username andpassword. An email was sent to panel members after two weeks as a reminder to complete andreturn the instrument. Results from Round I were tabulated, with

In addition, well planned blended learningenvironments potentially may improve pedagogy, increase accessibility and flexibility, andincrease cost effectiveness 2. Blended learning also shifts the responsibility of learning from theinstructor to the student. It lets students engage difficult material when they are ready, for as longor as little as necessary. This allows faculty to focus on the application of knowledge duringface-to-face meetings 3.There are some concerns that must be addressed when using blended or hybrid instruction.
