Schreinemakers Analysis - Problem #1: Analysis of an Invariant Point (Py-Sp-En-Sil-Cd)
Summary
This is a standard Schreinemakers problem: identifying the sequence of stable and metastable reactions around an invariant point.
Collapse
Context
Audience
I use this in my Petrology class as either an in-class exercise or as homework. It is NOT simple for some students and, so, may be best done in a group.
Skills and concepts that students must have mastered
They need to know the basic Schreinemakers process and logic.
How the activity is situated in the course
My petrology class is a studio class and so group activities and in-class work are key. This is one of many exercises the students do during the semester.
Goals
Content/concepts goals for this activity
The goal is to get them to (1) be able to do a Schreinemakers analysis, and (2) understand the significance of invariant points and stable/metastable equilibria.
Higher order thinking skills goals for this activity
Logic and visualizations are keys to the success of the exercise.
Other skills goals for this activity
Description of the activity/assignment
This is a standard Schreinemakers problem: identifying the sequence of stable and metastable reactions around an invariant point.
Determining whether students have met the goals
There is only one -- plus the enantiomorph -- correct solution, so evaluation is simple.
