Which of the following is the most effective checking-for-understanding practice?
◦ Asking the class, "Does everybody understand?" and noting the group's response.
◦ Saying to the class, "Raise your hand if you have any questions?"
◦ Stating to the class, "Give me a thumbs up if you understand and a thumbs down if you don't."
◦ Telling the class, "Hold up A if the word I say is an adjective, N if it is a noun, and V if it is a verb. I will say the word, use it in a sentence, and then say the word."
