Learning Assessment #5 - Geologic Time (2011)
Skills and concepts that students must have mastered
Students must have a good understanding of the basic principles of relative age (principle of superposition, cross-cutting relationships, original horizontality etc.), the difference between absolute and relative age and the concept of numerical age bracketing. Students also need to be familiar with different age dating methods (e.g. radiometric dating, fossils).
Knowledge of basic rock types (clastic and carbonate sedimentary rocks, intrusive and extrusive igneous rocks) and a general understanding of how they form is also necessary.

Description of the activity/assignment
Determining whether students have met the goals
Learning assessments are returned to students during a review period where the instructor devotes a class to going over the activity and explaining common errors. Learning assessments are graded using a checklist-style rubric which is a more detailed version of checklist provided to students with the assignment. Using the graded checklist as a guide, students complete a feedback activity during the review period, which gives them an opportunity to reflect on their understanding of the concepts covered in the learning assessment. The feedback activities are submitted, allowing the instructor to determine whether students have met the goals of the activity.
