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

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.

Students collect from two Devonian field sites. The goal is to determine the depositional environment and whether these are life or death assemblages.

Skills and concepts that students must have mastered

Basic sedimentary rock identification; identification of the major fossil taxa; life vs death assemblages, taphonomy/biostratinomy

How the activity is situated in the course

The lab is 2/3 of the way through the course; students have already surveyed the major fossil groups. It is a more advanced version of an earlier field lab (on stromatolites), and the lab final exam follows the format of this lab (with specimens rather than the field part of the lab!)


Content/concepts goals for this activity

Higher order thinking skills goals for this activity

Students will collect and interpret data (lithologies, fossils)

Other skills goals for this activity

Description of the activity/assignment

Students collect from two Devonian field sites. Each student works on their own collections; each genus is identified (and detailed sketches made), preservation noted, relative abundance reported; together with lithological information students are able to ascertain the mode of life of the fossils, and ascertain the depositional environment and whether these are life or death assemblages. The lab addresses the two 'content goals' of the course: assessing mode of life of an organism and determining the paleoenvironmental context.

Determining whether students have met the goals

Students submit a written report. A rubric is used (and is provided to students along with the report instructions so that they know how to organize their report).
