Geospatial Technologies: GPS and GIS

Active learning works well for geospatial technologies because students need to experience firsthand how GPS and GIS function rather than just read about them. By handling tools, interpreting data, and troubleshooting challenges in real contexts, students build durable spatial reasoning skills that static lessons cannot match.

GPS Scavenger Hunt: Mapping School Grounds

Provide students with GPS apps on school devices to locate and log coordinates for 10 features, like trees or benches, with photos. Groups compile data into a shared class map using Google My Maps. Discuss accuracy challenges encountered outdoors.

Analyze how satellite imagery has changed our understanding of environmental change.

Facilitation Tip

During the GPS Scavenger Hunt, circulate with a signal-strength app visible on your phone so students can see how obstructions affect their devices in real time.

What to look for

Present students with two scenarios: one describing a problem solved by GPS (e.g., finding a lost hiker) and another by GIS (e.g., mapping traffic patterns). Ask students to write one sentence for each scenario explaining which technology is primarily used and why.

GIS Layering Activity: Urban Planning Challenge

Using ArcGIS Online or Google Earth Engine, pairs add layers like roads, population, and parks to a city map. They propose optimal school sites based on criteria and justify choices with data overlays. Share proposals in a gallery walk.

Explain in what ways GIS helps urban planners make better decisions.

Facilitation Tip

In the GIS Layering Activity, give each group a large printed map base layer so they can physically trace and annotate changes before digitizing ideas.

What to look for

Pose the question: 'Imagine your school wants to create a new accessible pathway. How could GPS and GIS help plan this project effectively, and what privacy concerns might arise from mapping student movement?' Facilitate a class discussion, guiding students to consider data collection, analysis, and ethical implications.

Satellite Imagery Comparison: Tracking Change

In small groups, students access free Landsat images of Canadian sites, such as Alberta tar sands or BC glaciers. They compare images from different years, measure changes with tools, and hypothesize causes. Present findings with annotations.

Evaluate the ethical implications of constant location tracking and data privacy.

Facilitation Tip

For the Satellite Imagery Comparison, have students mark revisit dates directly on printouts to make temporal gaps concrete and discussable.

What to look for

Provide students with a blank map outline of their local community. Ask them to identify one feature they could map using GPS (e.g., a park entrance) and one type of data they could add to a GIS layer for that area (e.g., tree types). They should write one sentence explaining the benefit of mapping this feature.

Ethics Role-Play: GPS Privacy Debate

Divide class into roles: citizens, planners, police. Each group prepares arguments on GPS tracking benefits versus privacy risks, using real Canadian examples. Hold a structured debate with voting on policy recommendations.

Analyze how satellite imagery has changed our understanding of environmental change.

Facilitation Tip

In the Ethics Role-Play, assign roles based on real cases students researched so debates stay grounded in evidence they gathered.

What to look for

Present students with two scenarios: one describing a problem solved by GPS (e.g., finding a lost hiker) and another by GIS (e.g., mapping traffic patterns). Ask students to write one sentence for each scenario explaining which technology is primarily used and why.

A few notes on teaching this unit

Experienced teachers approach this topic by letting students struggle briefly with technology before scaffolding solutions, mirroring how geospatial experts troubleshoot in the field. Avoid lecturing about accuracy or bias; instead, create moments where students discover these concepts through data they collect themselves. Research shows this inquiry-based approach improves retention of spatial concepts compared to traditional instruction.

Successful learning looks like students confidently using GPS devices to locate points, analyzing GIS layers to explain patterns, and discussing ethical trade-offs with specific examples. They should connect technology use to real-world decisions and clearly articulate limitations they observed during activities.

Watch Out for These Misconceptions

• During GPS Scavenger Hunt, students may assume their devices will work perfectly indoors or under dense tree cover.

  Pause the hunt at three key obstructions and have students test signal strength, then compare results. Ask them to propose one workaround for each location using available school resources.

• During GIS Layering Activity, students may believe their final maps represent unbiased truth.

  Have groups present their map choices to peers, who must identify one selection that could influence interpretation. Students then revise their layers based on this feedback.

• During Satellite Imagery Comparison, students may think images update daily with fine detail like street-level photos.

  Provide two images of the same area taken years apart with different resolutions. Students annotate each image to identify delays and limitations, then write a one-sentence caption explaining their findings.
