Regarding lecture 16, Intro to QA testing, my feedback as a practitioner would be:

- Typo - "principle goals" / "principle techniques" instead of "principal"

- Add accessibility and internationalization under non-functional testing types, with at least a brief mention of their importance

- Add mention of exploratory testing under manual testing as a valuable technique

- Most of your students will not be QA staff themselves in their careers, so a brief mention of the benefits and pitfalls of collaborating with dedicated QA personnel may be useful. A mention that the type of QA personnel varies highly by software subspecialty and size of the business (ranging from non-technical to CS degree holding specialists) may also be useful.
