It points out that group work can make learners feel less anxious because it can provide learners with the sense of security and unity, besides, it can establish good relationship between the teacher and learners. Group work can also be motivating because it can fulfill the human needs for experiencing competence, relatedness and autonomy.展开更多

文摘This paper discusses group work from affective domain. It points out that group work can make learners feel less anxious because it can provide learners with the sense of security and unity, besides, it can establish good relationship between the teacher and learners. Group work can also be motivating because it can fulfill the human needs for experiencing competence, relatedness and autonomy.
