The document provides guidelines for how teachers should effectively respond to students' correct and incorrect answers. For correct answers, teachers should specifically praise the student's accomplishment rather than using generic praise. Nonverbal responses to correct answers, such as smiling and nodding, are more effective than frowning or looking bored. For incorrect answers, teachers should provide guidance to help the student arrive at the right answer, such as supplying missing information or breaking the question into smaller parts, rather than simply saying the answer is wrong.
