Objectives: Spatial visualization (SV) refers to the ability to manipulate geometric shapes in one’s mind and is important in many STEM fields. Studies have shown that SV skills are learnable, and SV training can increase GPAs and graduate rates in engineering. Additionally, sketching has been shown to be an important part of increasing 3D visualization skills, which is key for creativity and team communication. However, few engineering curricula include SV training, and adding new content to an already full program can be difficult. The Spatial Vis™ App, developed by eGrove Education, was designed with the potential to teach SV training outside of scheduled class time. It allows for freehand sketches of isometric and orthographic assignments to be graded automatically and for hints to be provided when needed. The app has been tested in a number of trials at universities across the country and has been shown to be an engaging and effective tool in improving SV skills. The app is currently available on Android and Apple smartphones and tablets, as well as advanced touchscreen Chromebooks. Features of the app include automatic grading, personalized hints for students when stuck, teacher data for tracking student progress, gradual increase in difficulty of assignments, a gamification start system to encourage persistence, and several test questions the end of each lesson where the Hint and Peek questions have been disabled. Results from trials using the technology in a number of university classroom settings, which have demonstrated the efficacy of the app based on a pre- and post- standardized spatial visualization test, will be discussed. Targeted audience: First year engineering or engineering graphics college or community college instructors; K-12 pre-engineering teachers and administrators.
Activities Planned: This workshop will provide an overview of the benefits and best practices of using the Spatial Vis app in your classroom. Participants will be given a license to the app to use on their own smartphone devices to engage in interactive spatial visualization (SV) activities.
Learning Outcomes: Instructors will learn 1) spatial visualization skills such as 2D rotations, 3D isometric views, and 2D orthographic projections; 2) how to use the app including the algorithm that automatically grades students’ sketches and provides guidance when requested; and 3) best practices for how to implement the SV training in their curriculum. You won’t want to miss this interactive workshop! Approximate length: 2 hours
Required supplies: Android or Apple touchscreen device such as a smartphone or tablet.
