Require Full Answers
When students get an answer right, there is a temptation to respond by saying “good” or “yes” and that’s that. The learning can and should continue after a correct answer has been given, so it’s great to remember to respond to right answers by asking students to answer a different or tougher question to make sure that a right answer is repeatable. This is especially true when students are asked yes or no questions and get them correct.
By requiring full answers, you avoid falsely concluding that reliable mastery of material has been achieved without eliminating the possibility that luck, coincidence, or partial mastery led to a right answer to the question asked.
