Importance of Developing Spatial Skills for Success in CS Laura Reasoner Jones
Well-developed spatial skills lead to success in Engineering and Technology Computer Science Chemistry Computer-Aided Design Mathematics Geospatial technologies Neurosurgery And much more Because they represent and manipulate information in problem-solving.
Gender Differences in Spatial Skills ~100 years of research finds significant gender differences favoring males in 3-D spatial skills Differences are particularly robust in mental rotation and spatial perception (Linn and Peterson, 1985) Experiences as youth seem to explain some of the differences (Baenninger and Newcombe, 1995, Voyer, Nolan, and Voyer, 2000, and Terlecki and Newcombe, 2005) Training seem to improve female performance to some degree (Baartmans and Sorby, 1996)
Components of Spatial Thinking Mental Rotation—rotate two and three-dimensional figures Spatial Perception—determine relationships with respect to the orientation of her/his body Spatial Visualization—multi-step manipulations of objects and parts both individually and holistically (AWE)
How can you improve measurable spatial skills? Teach students to: Analyze the components of the task Rotate the item into congruence Compare objects Respond
Important Experiences for the Development of Spatial Skills Play with construction toys/Legos Shop, drafting, and mechanics classes 3-D computer games Certain sports Mathematics skills Sketching Repeated practice with general spatial skills
Importance for Computer Science Spatial ability allows you to: Navigate in virtual space Develop mental models and maps Move between files and functions more easily Navigate through text/code more easily Figure out where to go next 3-D Printing…….
How can you improve functional spatial skills? Practice Experience Build confidence
Tests for Spatial Abilities: Mental Cutting Test
Mental Rotation Test (Vandenberg and Kuse, 1978)
Purdue Spatial Visualization Test: Rotations
Project Talent Study (APA, 2009)
What you can do Make thinking visible—use the Think-Aloud technique Teach mental rotation, 2-D and 3-D drawing (Sorby)
(Everyday Examples in Engineering) Use E3 Materials (Everyday Examples in Engineering) Sorby’s Engineering Graphics
Make 2D to 3D and 3D to 2D a part of the classroom life Logic groups Modeling as part of the programming process
Promote and use free CAD software Encourage exploration Allow experimentation & failure http://www.sketchup.com/learn/videos?playlist=58 https://tinkercad.com/video
