The effective implementation of evidence-based teaching (EBT) in large college courses benefits from the successful use of instructional teams. An instructional team's feedback allows instructors to act based on evidence of student learning, addressing students' needs. This feedback may be particularly important for novice instructors or experienced instructors teaching a class for the first time. This study sought to characterize the nature of an instructional team's feedback as well as its influence on the decisions and actions of a seasoned instructor teaching a new class. Instructional team members provided feedback in the form of anticipations, noticings, and suggestions. Anticipations and suggestions seemed to have the largest impact on the instructor's decisions and actions, while noticings, despite providing insights into student thinking, had a smaller effect. Our findings indicate that an instructional team can provide valuable feedback to instructors when team members have an opportunity to meaningfully participate in the planning and teaching processes.
