Active problem-solving confers a deeper understanding of science than does a standard lecture. But some university lecturers are reluctant to change tack.
Outbreak alert: six students at the Chicago State Polytechnic University in Illinois have been hospitalized with severe vomiting, diarrhoea and stomach pain, as well as wheezing and difficulty in breathing. Some are in a critical condition. And the university's health centre is fielding dozens of calls from students with similar symptoms.
This was the scenario that 17 third- and fourth-year undergraduates dealt with as part of an innovative virology course led by biologist Tammy Tobin at Susquehanna University in Selinsgrove, Pennsylvania. The students took on the role of federal public-health officials, and were tasked with identifying the pathogen, tracking how it spreads and figuring out how to contain and treat it — all by the end of the semester.
Although the Chicago school and the cases were fictitious, says Tobin, “we tried to make it as real as possible”. If students decided to run a blood test or genetic assay, Tobin would give them results consistent with enterovirus D68, a real respiratory virus. (To keep the students from just getting the answer from the Internet, she portrayed the virus as an emergent strain with previously unreported symptoms.) If they decided to send a team to Chicago, Tobin would make them look at real flight schedules and confirm that there were enough seats.
In the end, the students pinpointed the virus, but they also made mistakes: six people died, for example, in part because the students did not pay enough attention to treatment. However, says Tobin, “that doesn't affect their grade so long as they present what they did, how it worked or didn't work, and how they'd do it differently”. What matters is that the students got totally wrapped up in the problem, remembered what they learned and got a handle on a range of disciplines. “We looked at the intersection of politics, sociology, biology, even some economics,” she says.
