GEOLogic: Volcanologists

This activity was selected for the On the Cutting Edge Reviewed Teaching Collection

This activity has received positive reviews in a peer review process involving five review categories. The five categories included in the 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

Summary

GEOLogic questions are puzzles that were developed to support students understanding of geoscience concepts while challenging them to develop better logic and problem solving skills.
In this example, students are asked to resolve how many days each of 5 volcanologists spent at a volcano and what day they started for the volcano. There is also a second part where students are asked to do some additional research about volcanoes on the web.

Learning Goals

• To develop students' problem solving skills by requiring them to examine problems from multiple points of view
• To expose students to real geologic data and common concepts and units (rates, distance, time, etc.)

Context for Use

This activity is appropriate for a high school science class or an introductory level undergraduate geoscience course. The activity can be given as an in class assignment or for homework.

Teaching Notes and Tips

See the author's paper under Resources.

Assessment

As long as the student makes a substantial effort towards solving the problem, they receive credit for the assignment. Alternatively, GEOLogic problems could be used as extra credit exercises which would be graded more rigorously.
