Describe how you conducted your user test. Describe how you found your users and how representative they are of your target user population (but don't identify your users by name). Describe how the users were briefed and what tasks they performed; if you did a demo for them as part of your briefing, justify that decision. List the usability problems you found, and discuss how you might solve them.
We found our users by asking people who we knew were not experts in the language but had at least academic exposure. These people are part of our target population because they had a desire to review the vocabulary they already knew.
