In this study, we used a case study approach to obtain an in-depth understanding of the change process of two university instructors who were involved with redesigning a biology course. Given the hesitancy of many biology instructors to adopt evidence-based, learner-centered teaching methods, there is a critical need to understand how biology instructors transition from teacher-centered (i.e., lecture-based) instruction to teaching that focuses on the students. Using the innovation-decision model for change, we explored the motivation, decision-making, and reflective processes of the two instructors through two consecutive, large-enrollment biology course offerings. Our data reveal that the change process is somewhat unpredictable, requiring patience and persistence during inevitable challenges that arise for instructors and students. For example, the change process requires instructors to adopt a teacher-facilitator role as opposed to an expert role, to cover fewer course topics in greater depth, and to give students a degree of control over their own learning. Students must adjust to taking responsibility for their own learning, working collaboratively, and relinquishing the anonymity afforded by lecture-based teaching. We suggest implications for instructors wishing to change their teaching and administrators wishing to encourage adoption of learner-centered teaching at their institutions.
在本研究中,我们采用案例研究方法,深入了解了两位参与生物学课程重新设计的大学教师的转变过程。鉴于许多生物学教师对采用基于证据、以学习者为中心的教学方法存在犹豫,迫切需要了解生物学教师如何从以教师为中心(即以讲座为基础)的教学过渡到以学生为重点的教学。利用变革的创新决策模型,我们通过连续两次面向大量学生的生物学课程,探究了这两位教师的动机、决策和反思过程。我们的数据表明,转变过程在一定程度上不可预测,在教师和学生不可避免地遇到挑战时需要耐心和坚持。例如,转变过程要求教师从专家角色转变为促进者角色,更深入地讲解较少的课程主题,并给予学生一定程度的自主学习控制权。学生必须适应对自己的学习负责、进行合作学习,并放弃基于讲座教学所提供的匿名性。我们为希望改变教学方式的教师以及希望在其机构鼓励采用以学习者为中心教学的管理人员提出了相关建议。
