  1. Philosophy of education
  2. Educational psychology (scientific foundations of how people learn, with an eye to evidence-based theories about how to structure effective learning)
  3. Curriculum design
  4. Educational technologies
  5. Educational leadership and administration
  6. Special education and inclusive education
  7. Physical education and kinesiology
  8. STEM education
  9. Adult education
  10. Learning a second language
  11. Class management
