This is a summary of how I adapted an adaptation of the Keller mastery method to my part of MATH204 to forcefully encourage students to focus on the key ideas, rather than learn the trivial side-issues just to gain a Pass. The material is split into a number of equal Modules.
Students study at their own pace.
They sit for each module test when they are ready. Students must complete a set number of Modules to pass the subject. Students study the Core material in lectures. There is an oral component for the Core Exam, within 24 hours of the written component. They are allowed three attempts.
