About eGrove Education

eGrove Education co-founders Nate Delson and Lelli Van Den Einde are both Teaching Professors at the University of California San Diego. We see firsthand the importance of sketching when our students are working on design projects and sharing concepts with teammates.

Research shows that spatial visualization training can increase GPA and graduation rates for math and science majors [1]. Freehand sketching is a key part of spatial visualization training; the physical act of drawing 2D and 3D shapes increases one’s spatial visualization ability [2]. Benefits of spatial visualization training have been shown to be especially effective for women and other underrepresented minorities in math and science [3]. Sketching and spatial visualization are important skills, but rarely taught!

Our primary innovation is that we have replaced sketching on paper with drawing on a touchscreen. Our Apps provide immediate feedback and motivate students to persist until an assignment is solved. Sketches are automatically graded and customized hints are provided when students are stuck. Unlike multiple-choice questions, students can retry an assignment multiple times until they get it right. Teachers can view student data and see where they need extra help. The learning process is more engaging, more effective, and easier for students and teachers.

We began teaching our spatial visualization class using the App at UC San Diego in 2014. Since then, we have continued to conduct research studies surrounding the Spatial Vis™ app. You can find a summary of our findings on our Results page.
