1. This activity was selected for the On the Cutting Edge Exemplary Teaching Collection

    Resources in this top level collection a) must have scored Exemplary or Very Good in all five review categories, and must also rate as “Exemplary” in at least three of the five categories. The five categories included in the peer review process are

    • Scientific Accuracy
    • Alignment of Learning Goals, Activities, and Assessments
    • Pedagogic Effectiveness
    • Robustness (usability and dependability of all components)
    • Completeness of the ActivitySheet web page

    For more information about the peer review process itself, please see https://serc.carleton.edu/teachearth/activity_review.html.

  2. This activity has benefited from input from faculty educators beyond the author through a review and suggestion process. This review took place as a part of a faculty professional development workshop where groups of faculty reviewed each others' activities and offered feedback and ideas for improvements. To learn more about the process On the Cutting Edge uses for activity review, see http://serc.carleton.edu/NAGTWorkshops/review.html.

Critiquing Crummy Maps

Emily Burns, Community College of Rhode Island


Students work in groups to identify problems with a group of maps from the internet. Problems include lack of detail, lack of readability, no coordinates, and other issues.


Type and level of course
This activity was developed for an introductory-level ArcGIS course for students with a variety of abilities and skill levels. The students included several people in a surveying certificate program, a member of the engineering faculty at my college, and upper-level geology and geography students from other institutions. All had varying levels of experience with cartography and GIS.

Geoscience background assumed in this assignment
None needed

GIS/remote sensing skills/background assumed in this assignment
None needed

Software required for this assignment/activity:

Time required for students to complete the assignment:
About 15-20 minutes


GIS/remote sensing techniques students learn in this assignment
The activity helps students focus on what it is vital to include in a map and what should be left out. If they have no sense of how a map can be made readable and usable, they will be unable to produce good maps, even with good software.

Other content/concepts goals for this activity
Get them thinking critically and working in a group.

Higher order thinking skills goals for this activity
Looking at maps critically; evaluating problems, omissions, and design issues; learning what to avoid when making their own maps.

Description of the activity/assignment

Students are given a printout of several not very good maps and asked to critique them as a group. The maps are then projected at the front of the room one at a time and each group contributes their ideas.

Determining whether students have met the goals

I write down their responses and compare them with my own critique of the maps. When we did this, they came up with more problems than I had noticed.
