教导何以有方?教师辩证反馈对大学生团队创造力的作用机制

How to teach resourcefully? The mechanism of teacher dialectical feedback on team creativity of college students

采用实地问卷调查和纵向现场实验相结合的研究方法,从社会信息加工理论视角探讨了教师辩证反馈对大学生团队创造力的作用机制。结果发现:教师辩证反馈与团队创造力呈正相关关系;团队信息深加工中介了教师辩证反馈对团队创造力的影响;精熟氛围在教师辩证反馈与团队信息深加工关系间起正向调节作用,而绩效氛围在二者间起负向调节作用;教师辩证反馈能够通过团队信息深加工对团队创造力产生有条件的、正向的间接影响,当精熟氛围水平高、绩效氛围水平低时,教师辩证反馈对团队创造力的间接促进作用更为显著。研究从理论上提出教师辩证反馈并实证探索其对团队创造力的作用机制,从团队创新层面上丰富和深化了“教育与发展”这一经典理论范畴,并为促进大学生团队创造力发展提供了实践启示。

Teacher dialectical feedback reflects teachers’dialectical thinking and accord with college students’development rules,which is of great significance to boost students’team creativity.Less attention,however,has been given to the influence of teacher dialectical feedback on team creativity.Therefore,we expect to examine the effect of teacher dialectical feedback on team creativity and explore the underlying mechanism.To test our hypotheses,we conducted a field survey and a longitudinal field experimental study.The results overall provided support for our theoretical model and showed that(1)teacher dialectical feedback was positively correlated with team creativity;(2)team information elaboration mediated the relationship between teacher dialectical feedback and team creativity;(3)the interaction between teacher dialectical feedback and mastery climate significantly predicted team information elaboration, such that the positive relationship between teacher dialectical feedback and team information elaboration was stronger when mastery climate was high rather than low;(4) performance climate also played a moderating role in the relationship between teacher dialectical feedback and team information elaboration, such that the positive relationship between teacher dialectical feedback and team information elaboration was weaker when mastery climate was high rather than low;(5) the indirect effect of teacher dialectical feedback on team creativity through team information elaboration was significantly moderated by mastery climate and performance climate, such that when mastery climate was higher and performance climate was lower, the positive indirect effect is stronger, and vice versa. Drawing upon these findings, our work offers multiple contributions. First, this research expands the existing feedback paradigm and theoretical category of “education and development” by examining the effect of teacher dialectical feedback on team creativity. Second, our study enriches the theory of creativity and broadens the antecedents of team creativity by exploring the effect and mechanism of teacher dialectical feedback on team creativity. Third, this work provides novel insights into the mechanism through which teacher dialectical feedback influences team creativity from the perspective of team information processing. The results suggest that team information elaboration plays an important role for the effects of teacher dialectical feedback. Finally, by exploring the contingent role of team motivational climate, our study revealed the critical boundary condition for the effect of teacher dialectical feedback on team creativity, which provide a more integrative and accurate understanding of whether and when team performs more or less creativity as results of teacher dialectical feedback.
