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.

Saito et al.87later revised these steps to include identifying the quantity in the cross section after the rotationstep. Analysis by Saito et al. clarified that MCT errors rarely occurred in the first step. Theynoted that more than 70% of recorded error occurred during the second and third steps of theprocess (cutting and rotating the object). Just fewer than 30% of errors were due to the quantityidentification step in the process. For this study, analysis will be done on a virtual reality versionof the MCT using the aspects of pattern and

Of these, 15 have engineering graphics and/or design playing a role within the project.

Both are required courses in the curriculum.Figure 1 shows the content of this DFM class arranged pictorially and highlights the GD&Ttopics. The strategy adopted spreads these topics out over the duration of the term so that theyare presented concurrently with other DFM concepts.

With the development of Computer-aided design (CAD) software, many institutes and professors consider CAD as primarycourse content in engineering graphics.

IntroductionAlthough engineering students specialize in a variety of specialized areas, one essential part ofthe curriculum is learning and understanding measuring and modeling techniques that expressthe relationship between objects and space. Being able to visualize and conceptualize objects in3-dimensional space is a skill that is critical to success in STEM coursework and retention inengineering programs over time [1]. Spatial conceptualization ability is the capacity to learn,understand, and reason about the relationships of objects as they relate to space or other objects.Learning to conceptualize spatial relationships is crucial to STEM education, as it is thefoundation of skills that drive measuring, designing, and
