Research Problem
• A major recommendation from national studies (i.e.,
Vision and Change, AAAS/NSF; ASM Undergraduate
Curriculum Guidelines) on higher education in science is
to teach core concepts and to employ active learning.
• There are a wide variety of active learning methods.
• Instructors have little evidence to guide them on which
method to select for specific concepts.

Research Question
• Research Question:
• Do different active learning methods have different efficacies with
specific concepts for promoting student learning?
• If so, are students more favorable towards the method that is more
effective?
• Research Context:
• BIOL 3470, general microbiology course of 40 students required for all
Biology majors. SHSU is a regional public comprehensive university.
• My question is interesting because:
• The current body of literature strongly supports efficacy of active
learning in general; this study extends that by comparison of different
methods.
