| Sumario: | Understanding the link between course work and unanswered authentic research questions being explored in the research lab is an important goal in undergraduate science teaching. The activity presented here focuses on current research regarding the virulence characteristics of Streptococcus pyogenes particularly targeting the control of sugar uptake regulated via catabolite repression. Students were challenged to formulate a research question and use higher-order thinking skills to analyze data, work collaboratively to solve problems, and pose and test a hypothesis in the laboratory setting. The activity employed an interrupted case study approach using both online and face-to-face settings. The case story and problems were distributed online and were followed by in-class discussions and lab work. Aspects of the activity required independent thinking, as well as collaborative work. Student learning gains were demonstrated via comparison of pre- and postscores on the Host Pathogen Interactions (HPI) concept inventory, results from an end of semester Student Perception Survey, and from analysis of students’ work. |
