Such an approach can “replace andamplify real experiences” through proper guidance to “evoke or replicate substantial aspects ofthe real world” [4]. Simulated environments that can provide the high fidelity immersiveexperience, such as CAVE [5]–[7] or other forms of visualization representation can help thelearners create the necessary cognitive connection [3], [10] between the physical world and thecomputer-generated instance.

Each session included a detaileddescription of the project's curriculum design goals, and involved discussions on factual,conceptual and procedural knowledge, knowledge application, and student reflection. Handoutswere provided on methodology, instrumentation, procedure and assessing learning outcomes.The sessions gave instructors an opportunity to state their questions and concerns, and discusstheir long term curriculum development plans. The goal of the project is to develop students’ higher order thinking skills, problemsolving, technical visualization skills, and decision making skills in the context of a data-richlearning environment

Examples of statements used on the NCLAGES include: 1. “It is useful for me to do lots and lots of problems when learning graphics.” 2. “Learning graphics changes my ideas about how the world works.” 3. “In graphics, it is important for me to make sense out of engineering and design concepts before I can use them correctly.”Seven randomly selected sections of GC 120, Foundations of Graphics, were used in the study atNC State University. GC 120 is an introductory course designed to teach the fundamentals ofengineering/technical graphics.

This session could be for research in the growing fieldof pre-engineering education as it relates to our field, or just graphics education in general, either way, our field ofstudy is as popular as ever in the public schools, as it is in higher education, but no formal mechanism is in place forcommunications between the two groups.

Future work will address these questions.IntroductionSpatial-visualization skills (SVS) are known to be critically important to success and retention inSTEM fields. At the same time, these skills are often learned through life experiences such asplaying sports, or playing with certain toys, rather than being taught explicitly in a formal setting[1-4]. Due to this reliance on life experience, the levels of spatial skills displayed by women andunderrepresented groups are typically lower than that of other student populations. Importantlyhowever, spatial skills can be learned and improved with appropriate training.One of the most

Smith in 1964 [6] identified at least 84 career areas for which spatial skills areimportant. Women, underrepresented minorities, and non-traditional students have been foundto have somewhat lower spatial visualization skills affecting their performance in STEM fieldsbut after specialized training, they showed improvements in their skills [7] – [10]. A study byUttal, et al.

Simply having a “correct” volume or mass does not definitively prove apart has the correct shape. For example, Figure 12 shows that for the three advanced modelingparts in assignment four, the volume of the object was often within 1% of the correct answer yetthe shape was still incorrect; volume is only a fair proxy for accuracy.

In Chinese, the word “dougong” consists of twoparts, “dou” and “gong,” denoting the two basic elements of the dougong structure. Specifically,the word “dou” denotes the inverted cap for support, and the word “gong” denotes the bow-likeblock for supporting the load.

In computer aided design (CAD) education, thisprocess enhances students’ spatial visualization skills [2], as well as improves theircommunication with colleagues when the visualization tool is shared [3]. In particular, freehandsketching [4], or “a sketch done with only the hand and a pencil or pens”, is the quickest way tocommunicate technical information [5], [6]. It allows students to quickly visualize the problem,consider design options, and identify questions where more information is needed [7].
