Active learning ideas

Geospatial Technologies: GIS

Active learning helps students grasp GIS concepts because spatial thinking requires hands-on manipulation of data layers and visual problem-solving. By working with real local data, students move beyond abstract ideas to see how GIS reveals patterns and supports decisions like urban planners.

Activity 01

• Case Study Analysis
• 35 min · Pairs

Pairs: Local Layer Challenge

Pairs log into free ArcGIS Online or Google Earth Engine. They select their neighborhood, add three layers like roads, parks, and demographics, then identify one spatial pattern such as access inequities. Pairs share findings with the class via screenshots.

Explain how GIS helps urban planners make better decisions.

Facilitation Tip

During the Local Layer Challenge, circulate to ask pairs which overlay surprised them most and why.

What to look for

Provide students with a scenario: 'A city council wants to build a new community center.' Ask them to list three types of data layers they would use in a GIS to help decide on the best location and briefly explain why each layer is important.

Activity 02

• Case Study Analysis
• 45 min · Small Groups

Small Groups: Urban Planning Debate

Provide a scenario like siting a new community center. Groups layer data on traffic, green space, and population in a GIS tool. They justify their site choice with evidence from overlays, then debate against other groups.

Analyze how different data layers in GIS can reveal new spatial patterns.

Facilitation Tip

For the Urban Planning Debate, assign roles to ensure every student participates in data-driven arguments.

What to look for

Display an image of a GIS map with multiple overlapping layers (e.g., roads, parks, residential areas). Ask students to identify one potential spatial pattern or relationship that could be observed from this map and explain their reasoning.

Activity 03

• Case Study Analysis
• 50 min · Individual

Individual: Community Issue Map

Students choose a local issue like flood-prone areas. Individually, they create a simple GIS map with relevant layers, add annotations explaining patterns, and propose a solution. Share via class padlet for feedback.

Design a simple GIS project to address a local community issue.

Facilitation Tip

When students create Community Issue Maps, remind them to include a brief legend explaining their symbols.

What to look for

Pose the question: 'How might a GIS analysis of population density and access to grocery stores inform decisions about food security in a large urban area?' Facilitate a class discussion where students share their ideas and connect GIS capabilities to real-world problem-solving.

Whole Class: GIS Data Hunt

As a class, explore a shared GIS map of Ontario cities. Project it, vote on layers to add, discuss emerging patterns in real time, and connect to key questions like planner decisions.

Explain how GIS helps urban planners make better decisions.

Facilitation Tip

During the GIS Data Hunt, provide a checklist of 5 key features to find in each map resource.

A few notes on teaching this unit

Start by modeling how to overlay layers slowly, narrating your thinking about which combinations reveal useful insights. Avoid rushing to conclusions by emphasizing that GIS analysis involves trial and error. Research shows students learn spatial reasoning best when they wrestle with incomplete data and revise their maps based on feedback.

Successful learning looks like students confidently explaining how overlaying data layers exposes relationships, such as how population density and transit access influence school site selection. They should also justify their choices using evidence from their maps and discussions.

Watch Out for These Misconceptions

• During the Local Layer Challenge, watch for students who focus only on map colors or labels without analyzing the data relationships.

  Prompt pairs to explain what the overlap between two layers suggests about local issues, like how areas with high tree coverage and low population density might indicate park access gaps.

• During the Urban Planning Debate, listen for groups that treat data layers as static or unrelated to each other.

  Challenge each group to justify why combining transit lines with population density changes their site recommendations, using the provided map layers as evidence.

• During the Community Issue Map activity, watch for students who select data layers based on aesthetics rather than analytical value.

  Ask students to write a one-sentence reasoning for each layer they include, linking it directly to their community issue, such as bike lanes and safety near schools.
