Factors Influencing the Use of Evidence-based Instructional Practices by Community College Biology Instructors.

ABSTRACT

Evidence-based instructional practices (EBIPs) have been shown to benefit students in undergraduate biology, but little is known about the degree to which community college (CC) biology instructors use EBIPs or the barriers they encounter. We surveyed CC biology instructors to characterize how they use EBIPs, their capacity to use EBIPs, and perceived barriers to their use, and to explore which factors are associated with EBIP use. CC biology instructors report using EBIPs to a similar degree as other populations of undergraduate biology faculty; they generally believe EBIPs to be effective and are motivated to use EBIPs. Consistent with the theory of planned behavior, instructor belief in EBIP effectiveness, collegial support, and perceived knowledge of and skill in using EBIPs positively influence their use. The main barriers to using EBIPs reported by CC instructors included the need to cover large amounts of course content, lack of time to prepare for using EBIPs, and student resistance. Our findings point to a number of approaches that may promote the use of EBIPs by CC biology instructors, including professional development to increase instructor knowledge and skill, addressing tensions between content volume and the use of EBIPs, and providing resources to make implementing EBIPs time efficient.
