Introductory laboratory courses are a standard component of undergraduate science programmes and historically taught using direct instruction/confirmatory lab models. Previous studies have shown that inquiry-based labs enhance student engagement in science courses. However, research on how direct instruction introductory lab courses effectively engage undergraduate students is lacking. This study, therefore, using a mixed model design, examined student engagement in an introductory direct instruction microbiology lab. Data was collected through self-report surveys, classroom observations, and interviews at a Midwestern, post-secondary institution in the USA. The findings suggest that students found the lab activities engaging. This study provides baseline data which describes student engagement and student perspectives in a direct instruction undergraduate microbiology lab course. This baseline data can be used in further research against which comparisons can be made when studying other types of lab teaching interventions.
