Research at all grade levels (Rowe, 1987; Tobin, 1987) has found that when a faculty member asks his or her students a question, he or she allows less than one second of silence before speaking again. 


“Wait time” is the term that has been used to describe the interval of silence after a teacher’s question and the start of a student’s reply.  “Wait time” has also been used to describe the interval of silence after a student’s answer before the teacher provides further explanation or elaboration.

 

When faculty extend the “wait time” following a question from less than one second to 3-5 seconds, several significant educational benefits result, including:

·        The length of students’ responses to your questions will increase dramatically

·        Students are more likely to support inference statements by the use of evidence and logic based on evidence

·        Students do more speculating about possible alternative explanations or ways of thinking about a topic

·        The number of questions asked by students increases

·        Failures to respond to your questions decreases

·        Student-to-student exchanges increases

·        The variety of students participating voluntarily in discussions increases as does the number of unsolicited but appropriate contributions

·        Students gain confidence in their ability to construct explanations and to challenge the logic of a situation

·        Achievement on written measures improves, particularly on items that are cognitively more complex

 

Faculty should be aware that:

·        These changes in student behavior don’t happen immediately. For a bit, students will continue to wait for the few with the quick hands to answer every question.  But persistence pays off.

·        Prolonged intervals do not produce improved results; limit the maximum interval of silent think time to 10-15 seconds

·        If the teacher refrains from commenting after a student’s response, it encourages more student-to-student interaction

·        Students will stop responding to instructor questions when they see that, following a student’s response, the instructor habitually offers a “Yes but…” reaction

·        It is important to avoid the “guess-what-I-am-thinking” game in which the lecturer asks what appears to be an open-ended question, but is in fact looking for a particular answer.  When this game is played, the teacher rejects what normally would be considered acceptable answers until the “correct answer” is given (Whitman, 1988).
