Maps as Tools for Advocacy

Active learning works for this topic because maps become powerful teaching tools when students don’t just look at them but actively interrogate and create them. When students analyze, design, and discuss advocacy maps, they move from passive map consumers to critical mapmakers who recognize how spatial representation shapes power and policy.

Learning Objectives

1. Analyze how specific mapping tools, like GIS or community-generated maps, can amplify the voices of marginalized groups.
2. Evaluate the ethical implications of data visualization choices in advocacy maps, considering potential biases and misrepresentations.
3. Design a spatially-informed advocacy campaign proposal for a local social justice issue, including target audience and proposed map products.
4. Critique existing maps of local areas to identify how they may obscure or misrepresent the experiences of certain communities.

Socratic Seminar

⏱ 45 min·Pairs

Analysis Activity: Unpacking a Redlining Map

Students examine historical HOLC redlining maps of a US city alongside current demographic, income, and health data for the same neighborhoods. In pairs, they identify specific spatial correlations and discuss the long-term geographic consequences of discriminatory cartography on present-day community patterns.

Prepare & details

Explain how maps can be used to advocate for marginalized communities.

Facilitation Tip: During the Unpacking a Redlining Map activity, ask students to circle every boundary, label, and color choice on the map and annotate what each choice might reveal about the mapmaker’s priorities.

Setup: Chairs arranged in two concentric circles

Materials: Discussion question/prompt (projected), Observation rubric for outer circle

Socratic Seminar

⏱ 60 min·Small Groups

Design Challenge: Map an Injustice

Small groups select a local or national social justice issue , environmental pollution, transit access gaps, food deserts, or unequal park distribution , and design a map-based advocacy campaign. They decide what data to show, what to omit, how to title the map, and who their audience is, then present their design choices to the class.

Prepare & details

Analyze the ethical responsibilities of geographers in data representation.

Facilitation Tip: In the Map an Injustice design challenge, require students to write a one-paragraph justification for each mapping decision before they begin drawing.

Setup: Chairs arranged in two concentric circles

Gallery Walk

⏱ 35 min·Pairs

Gallery Walk: Maps That Changed Things

Historical and contemporary advocacy maps are displayed around the room: John Snow's cholera map, NAACP lynching maps, Indigenous land claim maps, and climate justice maps. Students annotate each station with what injustice the map reveals, who made it, and what documented effect it had on policy or public understanding.

Prepare & details

Design a map-based advocacy campaign for a local social justice issue.

Facilitation Tip: For the Gallery Walk, have students rotate with sticky notes to write questions and critiques directly on the maps they examine, creating a visible trail of analysis.

Setup: Wall space or tables arranged around room perimeter

Materials: Large paper/poster boards, Markers, Sticky notes for feedback

Fishbowl Discussion

⏱ 40 min·Whole Class

Fishbowl Discussion: Geographers' Ethical Responsibilities

An inner circle of four to six students debates the ethical obligations geographers have when their data could harm vulnerable communities. The outer circle observes and takes structured notes. Circles rotate halfway through so all students engage in both active debate and reflective listening.

Prepare & details

Explain how maps can be used to advocate for marginalized communities.

Facilitation Tip: During the Fishbowl Discussion, assign half the class to remain silent observers who record key ethical tensions raised by the discussion participants.

Setup: Inner circle of 4-6 chairs, outer circle surrounding them

Materials: Discussion prompt or essential question, Observation notes template

Teaching This Topic

Teachers should approach this topic by making the invisible visible. Instead of treating maps as neutral tools, model skepticism by exposing students to maps that deliberately obscure or highlight data. Avoid presenting advocacy mapping as inherently good or bad; instead, focus on how ethical considerations shape design choices. Research suggests that when students create maps themselves, they develop deeper understanding of how representation influences perception and policy outcomes.

What to Expect

Students will demonstrate understanding by identifying how cartographic choices encode values, designing maps that explicitly advocate for justice, and articulating ethical responsibilities in geospatial advocacy. Success looks like students questioning official narratives and creating maps that communicate complex social issues effectively to diverse audiences.

Watch Out for These Misconceptions

Common Misconception

During the Unpacking a Redlining Map activity, students may claim maps are objective because they display data visually rather than making written arguments.

What to Teach Instead

During Unpacking a Redlining Map, have students trace the redlined boundaries in red pen and the greenlined boundaries in green pen, then write a short paragraph explaining whose priorities each color choice might serve and what communities might be excluded by these color choices.

Common Misconception

During the Map an Injustice design challenge, students may assume community-produced maps are less reliable than government or academic maps.

What to Teach Instead

During the Map an Injustice challenge, provide students with a sample community-produced map alongside an official map of the same issue. Ask them to identify three pieces of hyper-local knowledge captured in the community map that the official map omits.

Common Misconception

During the Fishbowl Discussion, students may believe advocacy maps are inherently biased while scientific maps are neutral.

What to Teach Instead

During the Fishbowl Discussion, assign students to prepare one question about how transparency in data sources and methods could make advocacy maps more credible than official maps for addressing social injustices.

Assessment Ideas

Discussion Prompt

After the Unpacking a Redlining Map activity, present students with two maps of the same neighborhood: one from a city planning department and another created by a local community group. Ask: 'How do these maps differ in what they emphasize or omit? What specific advocacy goals might each map serve? Which map do you find more persuasive for advocating for residents' needs, and why?'

Quick Check

After the Map an Injustice design challenge, provide students with a short case study of a social justice issue, such as food deserts. Ask them to list three types of spatial data they would need to map this issue effectively and explain why each data type is crucial for advocacy.

Peer Assessment

During the Fishbowl Discussion, have students draft a brief proposal for a local advocacy map. They exchange proposals and assess them using a checklist: Does the proposal clearly identify a local social justice issue? Does it specify the target audience for the map? Does it suggest at least one specific mapping technique or data source and justify its use? Peers provide one written suggestion for improvement.

Extensions & Scaffolding

• Challenge: Ask students to create a dual-layer map—one layer showing official data and the other showing community-collected data—and write a 200-word reflection on how the two layers tell different stories.
• Scaffolding: Provide students with pre-labeled data sets and a partially completed map template to reduce cognitive load during the Map an Injustice design challenge.
• Deeper exploration: Invite a local community organizer or data journalist to share how they use maps in their advocacy work, then have students revise their designs based on the guest’s feedback.

Key Vocabulary

Participatory GIS (PGIS)	A geographic information system approach that actively involves community members in the mapping process, valuing local knowledge alongside technical expertise.
Spatial Justice	The fair distribution of geographic resources and opportunities, and the equitable treatment of all people regardless of their location or identity.
Data Gentrification	The process by which data, often collected by outsiders, is used to justify development or policies that displace existing communities or alter their character.
Environmental Racism	The disproportionate exposure of certain racial or ethnic groups to environmental hazards and pollution, often linked to historical and ongoing discriminatory practices.
Redlining	A discriminatory practice where services, like loans or insurance, are denied to residents of certain geographic areas, often based on race or ethnicity, leading to persistent inequality.
