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

Summary

This lab is designed to be a highly interactive lab session for a petrology course, where instructors provide a minimal level of essential background and then the entire group works together to explore mineral chemistry.

Context

Audience

This exercise is used in a sophomore or junior level required course in petrology.

Skills and concepts that students must have mastered

How the activity is situated in the course

I find this lab works very well as a bridge between two semesters of a typical Mineralogy-Petrology sequence. Having completed crystallography, systematic mineralogy and optical, students find this a welcome change of pace and it helps them to start thinking about how mineral associations form the basis of petrology. It is also a great reinforcement and integration of mineralogy and chemistry, allowing you to leap off into crystal chemistry more deeply.

Goals

Content/concepts goals for this activity

This is an activity that is used to introduce students to instrumentation used in petrology. It should help students integrate mineralogy and chemistry.

Higher order thinking skills goals for this activity

This activity involves data analysis.

Other skills goals for this activity

This activity involves understanding how analytical equipment works.

Description of the activity/assignment

This lab is designed to be a highly interactive lab session for a petrology course, where instructors provide a minimal level of essential background and then the entire group works together to explore mineral chemistry. In using a new piece of technology, students can "learn as they go." The point is not to understand every aspect of how an instrument works or to become proficient users, but rather to use the visual impact of the output to catch their interest and advance their analytical skills in the process. I find this lab works very well as a bridge between two semesters of a typical Mineralogy-Petrology sequence. Having completed crystallography, systematic mineralogy and optical, students find this a welcome change of pace and it helps them to start thinking about how mineral associations form the basis of petrology.

Determining whether students have met the goals

Students have met the goals of this assignment if they are able to complete the exercise accurately and completely.
