Module 2 Learning Goals

Academic success in Module 2 means that students demonstrate proficiency and comfort with the concepts below.

The expected mastery level can be understood with the following scale:

  • Mastery: student is able to explain and implement the concept independently or with light reference
  • Functional: student recognizes when to use the concept and can implement it with the support of documentation and/or a collaborator
  • Familiarity: student can recognize and describe the concept when needed/appropriate, but is not able to implement the technology/technique
