text: In online school you can't show mastery of the skill in the same ways you could if you were in a classroom, but there is other ways to prove your knowledge. In school you take tests to prove mastery of the skill or topic you've just learned. If you were doing online school, those same tests would be extremely easy, as you could just look at your notes. However, there are many other ways to show mastery of a skill. Teachers have proposed open note quizzes or an essay format type of test. They could also assign projects or slide-shows to force the students to actually have to research and learn about the topic they are supposed to be tested on. There are many ways you can show mastery without having to do a multiple choice quiz or test.
