Active learning ideas

Secondary Data Analysis and GIS

Active learning works for secondary data analysis and GIS because students need to test data against real spatial problems. When they manipulate layers and compare sources themselves, they move beyond abstract ideas to concrete evidence. Hands-on work builds the spatial reasoning skills required to interpret patterns in Australian regional contexts.

Activity 01

• Problem-Based Learning
• 35 min · Pairs

Pairs: Local GIS Overlay

Provide access to a free GIS viewer like ArcGIS Online or Google Earth Engine basics. Pairs select their suburb, overlay census population and satellite land cover layers, and identify three spatial patterns. They screenshot findings and explain relationships in a shared class document.

Analyze how GIS layers can reveal spatial patterns and relationships.

Facilitation Tip

During the Data Layers Gallery Walk, provide sticky notes in three colors for students to categorize observations: patterns, questions, and ethical concerns.

What to look for

Present students with a scenario: 'A city council wants to build a new park. They have data layers for population density, existing parkland, and proximity to major roads.' Ask students to list two GIS data layers they would use and explain why each is important for this decision.

Activity 02

• Problem-Based Learning
• 45 min · Small Groups

Small Groups: Secondary Data Scavenger Hunt

Groups search Australian Bureau of Statistics or Geoscience Australia sites for data on a theme like drought or migration. They classify types, note sources, and rate reliability on a rubric. Groups present one ethical concern found.

Differentiate between various types of secondary geographical data (e.g., census, satellite imagery).

What to look for

Pose the question: 'When using publicly available census data, what are two potential ethical concerns we should consider?' Facilitate a class discussion, guiding students to consider privacy, data accuracy, and potential for misuse or misinterpretation.

• 40 min · Whole Class

Whole Class: Data Layers Gallery Walk

Display printed or projected GIS maps with varying layers around the room. Students walk, add sticky notes with observations and questions, then regroup to discuss patterns and data choices as a class.

Evaluate the ethical considerations when using publicly available geographical data.

What to look for

Provide students with a simplified map showing two overlaid GIS layers (e.g., population density and location of fast-food outlets). Ask them to write one sentence describing a spatial relationship they observe between the two layers and one question they have about the data.

• 25 min · Individual

Individual: Ethical Data Diary

Students review a dataset like satellite imagery of bushfires, journal potential biases or privacy issues, and propose one improvement. Share two entries in a class Padlet for feedback.

Analyze how GIS layers can reveal spatial patterns and relationships.

A few notes on teaching this unit

Teach GIS by starting with a familiar local context students can visualize, then layer abstract data gradually. Avoid overwhelming students with too many tools at once. Research shows that sequencing from simple overlays to complex analysis improves spatial reasoning and retention.

Students will demonstrate the ability to evaluate data quality, identify spatial relationships, and explain how GIS layers support informed decision-making. Success looks like clear justifications for data choices, accurate pattern detection, and thoughtful discussion of ethical considerations.

Watch Out for These Misconceptions

• During Local GIS Overlay, watch for students who assume the map’s colors represent absolute truth.

  Provide a data source sheet and ask pairs to note each layer’s collection method and date, then discuss how collection bias or outdated info could distort the visual.

• During Secondary Data Scavenger Hunt, watch for students who dismiss secondary data as less valuable than primary sources.

  Have groups compare a census block with student-collected survey data on the same street, then list two strengths of each type before ranking their usefulness for a park location decision.

• During Data Layers Gallery Walk, watch for students who treat GIS as a tool for making maps, not for revealing patterns.

  Assign each student a guiding question on their sticky note, such as 'What relationship do you see between flood zones and housing density?' to shift focus from aesthetics to analysis.
