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
For more information about the peer review process itself, please see http://serc.carleton.edu/NAGTWorkshops/review.html.
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.

Description of the activity/assignment
Determining whether students have met the goals
However, students each write up their own final interpretation and limitations. Additionally, there is generally a lot of discussion between students and instructors about clues during the exercise.

More information on this exercise and examples of clues can be accessed through a powerpoint

For this activity I use two dinosaur sites:
1) Cleveland-Lloyd Quarry
Bilbey, 1999 (Gates, 2005)
2) Yale Deinonychus Quarry
Maxwell and Ostrom, 1995
I chose these sites because they are:
1) controversial with multiple interpretations.
2) have references with the needed clues.
3) relate to class lectures on behavior.
Additionally, within the classroom I prefer to have
adjacent groups(tables) working on different sites.
Clues are on separate sheets of paper that provide brief descriptions of various site attributes.
For example, there may be sheets on the dinosaurs species represented, bone weathering, lithologies, sedimentary structures, bite marks, etc.
Students request information one clue at a time. To receive a clue, they must formulate a hypothesis and explain how a specific type of information would test that hypothesis. For example, they might propose the assemblage represents a mass mortality and request information on bone weathering. A hypothesis might be that if the dinosaurs died together at one time, their remains should show uniform weathering.
In practice, the exercise requires the instructor to provide some prompts/assistance to students in linking hypotheses with physical/observable information.
Suitable for any taxonomic group - mammals, trilobites, reef assemblages. Just get the right reference or make it up.
Perhaps suitable for general vert/invert. paleontology class where specimens unavailable.
