Learners react differently to engaging in active learning. Some learners are eager to jump in and interact while others are reticent for a variety of reasons. Some may be threatened by high levels of involvement when they lack self-confidence or self-esteem and when they feel forced to perform in front of peers or strangers. Under these circumstances, it may be best to avoid high levels of involvement in the early stages of instruction. One strategy to overcome this problem is to begin with activities characterized by low levels of learner involvement and introduce higher levels of learner involvement when the learners are "warmed up." Another strategy is to introduce the learners to active learning with activities that are noncompetitive. Educators can also encourage learners to be supportive of one another so that a nonthreatening atmosphere is created.
