Spatial thinking is thinking that finds meaning in the • shape, • size, • orientation, • location, • direction, or • trajectory
….of objects, processes, or phenomena,
….or the relative positions in space of multiple objects, processes, or phenomena.
• Describing the shapes of natural objects, rigorously and unambiguously. Categorizing objects by their shape. Ascribing meaning to the shape of a natural object.• Recognizing a shape or pattern amid a cluttered noisy background. Visualizing a 3-D object or structure or process by examining observations collected in one or two dimensions. Describing the position and orientation of objects in the real world relative to a coordinate system anchored to the Earth.

• Recalling locations of previously observed geological phenomena.
• Mentally manipulating a volume by folding, faulting, and eroding.
• Envisioning the motion of objects or materials through space in three dimensions.
• Making and interpreting spatial representations (including maps).
• Using spatial thinking to think about time.
• Using spatial thinking to think about non-spatial properties.

Spatial cognition is a well-developed field of cognitive and learning science research
Downs and Liben (1991) studied college students’ ability to anticipate the form of a shadow cast by a shape rotated to various angles.

They found that college students performance on projective tasks is poor when the shapes are three dimensional.

Performance on spatial tasks shows wide person to person variation.
Students who struggle with typical verbally-demanding academic tasks may excel on spatially-demanding tasks.

Computer-supported instructional activities to foster spatial thinking in Earth Sciences, developed by Steve Reynolds
Spatial thinking can be improved through instruction and practice.
Spatial Thinking in Earth System Science
• Teachers need to know that spatial thinking is pervasive in Earth & Environmental Sciences
• Teachers need to understand that performance on spatial tasks:
• differs widely among individuals• does not necessarily correlate with other
academic strengths,• can be improved with instruction and practice.
• Teachers need to be able to design, select, and evaluate student activities that develop and assess spatial thinking.

Professional Development to Improve the Spatial Thinking of Earth Science Teachers and Students http://earth2class.org/site/educational-resources/spatial-thinking/• Analyze released New York State Earth Science
Regents exam items for spatial thinking: • What is abundant?• What is hard?
• Pilot and evaluate a professional development program for Earth Science teachers piggy-backing on Earth2class
• Expand spatial thinking professional development statewide and nationwide, leveraging move towards data-driven PD (?)
“Finding the Spatial” inEarth Science Regents Exams
• Began with exploration of RES Core Curriculum, exams, and practices
• Gradual identification of sub-categories wrt RES:
• Spatial concepts• Spatial representations• Spatial skills
• Coded 12 exams: 2008-2011
Analyses revealed “spatialness” can be identified in:
63.6 % of all questions
63.3 % of the multiple choice questions 64.0 % of the constructed response questions
Spatial thinking is abundant in Regents Earth Science Exam
Total items (out of 84 or 85)
Multiple choice items (out of 50)
Constructed response items (out of 34 or 35)N

Difficulty of spatial versus non-spatial items • 26 school districts in
one BOCES region• One exam (June 2010)
Mean of Non-spatial items =73% correct
Mean of Spatial items =66% correct
12 out of the 13 hardest items are spatial
Difficulty of spatial versus non-spatial categories
• Hardest Spatial Concepts• Trajectory (14 percentage points worse than average spatial item)
• Gradient (5 points worse)
• Hardest Spatial Representation• Solar System (9 points worse)
• Hardest Spatial Skills• Describe spatial phenomena (5 points worse)
• Perspective taking (4 points worse)
Hard Spatial Item (44.9% correct)

Hard Spatial Item (44.0% correct)
SC: GradientSC: PositionSC: Configuration
SR: Profile
SS: Describe
Allowed answers:
— Heat and pressure increase from B to C.
— Regional metamorphism is greatest at C.
— different grades of metamorphism
Easy Spatial Item (93.1% correct)
Earth Science Reference Tables
SC: Position
SR: Map
SS: Representational Correspondence
• A wide range of spatial concepts, spatial representations, and spatial skills are being assessed on the Earth Science Regents.
• Configuration, position, motion and direction are the most frequently assessed spatial concepts.
• Mental animation and representational correspondence are the most frequently assessed spatial skills.
Conclusions
• Earth Science Reference Tables enable more challenging questions using spatial representations, especially maps & profiles
• Spatial questions are more difficult than non-spatial questions for students.
• Questions involving gradient, trajectory, and solar system diagrams are the most difficult (in a limited data set)
Next Steps
Utilize: Pilot project on professional development on spatial thinking for Earth Science teachers
Dream: Expand spatial thinking professional development statewide and nationwide, leveraging movement towards “data-driven” PD.
