classroom setting.Introduction The effectiveness of using simulation-based learning strategy for procedural knowledgeor skills has been reported by many researchers [1]–[3]. 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. With the technological advancement in visual computing, simulation-based learningthrough technology such as virtual reality (VR) that

manystudent failures within each assignment.There is a variety of pedagogical methods employed in these courses, and the creation of“correct” models and drafts can be have multiple correct procedures [1], [2]. Yet, there arefundamental concepts in visualization and definitions of views that should always be taught inthe beginning of CAD instruction. For example, in learning about two-dimensional sketching, astudent should understand how the application presents its 3-D space, origin, and coordinatesystems.Further, mobile computing platforms are dominating the higher learning institution market, atleast in the U.S, with price-points decreasing and sufficient hardware becoming ubiquitousacross the top vendors. This lends to the ability for each student

implementing the resulting design inCAD software. Namely, ideation, modeling strategies, and problem solving learning moduleswere included in the course. To determine the efficacy of this approach, the following researchquestions were posed: 1) is it feasible to use individual whiteboards to teach freehand sketchingin a large undergraduate CAD course? 2) do students and instructors find this approachacceptable? 3) do students find that the use of whiteboards during class improves their ability tosketch? The acceptability and effectiveness of the approach was tested using pre- and post-student surveys. Additionally, performance on exam questions related to modeling strategies wasanalyzed across students over time to determine whether the whiteboarding

statisticallysignificant level. TAs are effective at providing informative feedback that provides direction forimproving the model, but it is a time consuming process. At this time, the software is not able tooffer substantial and specific feedback to the students on how to improve, and it is recommendedto use the computational grading tools in conjunction with human graders. Using the software toprioritize which files need TA feedback, those with similarity scores below a threshold value,may lead to a more efficient and effective use of resources to provide a quality feedback loop.Introduction and MotivationAt Clemson University, the introductory engineering graphics course, ENGR 2080, usesSOLIDWORKS [1] to teach 3D modeling of parts and assemblies.

low spatial skills.Keywords: spatial reasoning, apps, augmented reality, engineering educationI Background Spatial visualization is the ability to mentally represent and manipulate two-dimensional(2D) and three-dimensional (3D) figures. Spatial skills are often used in STEM careers, such asthose in engineering and medicine, and have been positively correlated with increased grade pointaverages and retention in STEM-related fields, including math, engineering, computerprogramming, and science [1, 2]. Spatial visualization skills are learnable [1, 3, 4], but moststudents do not receive formal instruction in K-12 or at the university level. In addition, a particularlack of exposure to spatial visualization skills may explain why women

to SpatialVisualization (SV) training specifically in the area of providing feedback hints to students whenperforming freehand sketching exercises on touchscreen devices.SV is the ability to visualize and manipulate 2D and 3D shapes in one’s mind. This skill has beentied to success in many careers, yet this skill is undertaught or not typically taught in most K-12and engineering curricula. A seminal study by Sorby [1] showed that SV skills can be taught andcan result in a significant increase in GPAs and graduation rates. 7000 students were tracked forover 15 years showing similar results [2]. The increase in graduation rates is especiallysignificant for women and other underrepresented minorities in STEM [3], who may have hadless experience

Monitoring the EGCI’s performanceagainst current trends and practices in engineering graphics can help keep the instrument a usefultool in engineering education research. With the instrument having met its intended level of rigor[1], widespread testing can now be done on different psychometric aspects to better prepare it forwidespread use. One of the first measures to be further substantiated is the instrument’s validity.BackgroundThe EGCI was developed as part of a larger project examining understanding andmisconceptions in engineering graphics with a goal of creating an assessment instrument.Experts in the field were consulted to identify important topics in the field which included

engineering,spatial visualization ability is essential to many applications, beginning with engineeringgraphics. Engineering graphics courses are commonly introductory-level classes in engineeringprograms, creating challenges for women, who on average score lower on tests of spatialvisualization ability. Improved understanding of gender differences in engineering graphicsclasses could therefore help identify pedagogical areas to support women and increase theirretention in engineering programs. Although a gender gap exists in spatial ability andperformance in engineering graphics classes, female students still achieve positive courseoutcomes. We hypothesize that: 1) female students put more effort into engineering graphicscourses; and 2) that this

A main goal pursued with those initiatives is toimprove the students’ spatial visualization skills, as measured by their scores in a standardizedvisualization test, by comparing the pre-initiative and the post-initiative performance of thestudents. Thus having as well an indication of the effectiveness of the implemented initiative.There are several tests that have been applied to measure spatial visualization skills of students[1, 2], and there are numerous studies that have collected and analyzed information regardingdemographics, spatial visualization skills, and academic performance [3, 4].

According to Cavus et al. [1], “An LMS isoften regarded as the starting point for developing an online course or program by researchers asit provides a means for managing, delivering, and tracking online instruction and studentoutcomes.” Furthermore, an LMS also acts like a bridge between the instructors and learners byproviding a common point of contact and direct line of connection [1].To be an effective system, an LMS must meet several requirements: availability, scalability,usability, interoperability, stability, and security [2].

.    Introduction  Spatial reasoning is an important predictor of student success in STEM fields [1], [2]. Sorby  reports that spatial cognition has been a focus of research for nearly a century. One important  part of spatial cognition is "spatial visualization, which is defined as the process of  'apprehending, encoding, and mentally manipulating three dimensional spatial forms'" [3].  Given this importance of spatial visualization, an important question is if and how students'  spatial visualization skills can be developed. Sorby studied the effect of students taking a 1-credit  spatial skills course, and found multiple benefits: improved performance in introductory
