Science, Technology, Engineering and Mathematics (STEM) Epidemiology Project with Seventh Grade Middle School Classes

BACKGROUND: Research focused on project-based learning has shown that real world projects can increase a student’s interest in science, technology, engineering and mathematics (STEM). This is due to students becoming involved in solving real life problem solving, working with others and building practical solutions to the issue at hand. In 2013, DeKalb County Board of Health (DCBOH) became a partner with Tucker Middle School for project based learning in Epidemiology for their STEM program. The project was then replicated in 2015 with the seventh grade mathematics and science class and an analysis of the project was completed. The project consisted of an integrated approach to STEM education focused on students learning what happens within local public health and how an epidemiologist solves an outbreak investigation.   

METHODS: Students received a lesson on “a day in the life of a local epidemiologist” and taught how to solve basic epidemiologic calculations including developing epidemiology curves, calculating incubation periods and solving the risk of food items through two by two tables. Students were provided a pre- and post-test to gauge their current knowledge of epidemiology and to test what they learned during the project. Students investigated a simulated “real life” outbreak and presented their finding at the DCBOH to staff and their peers.   

RESULTS: A total of 52 students took the pre-survey and 53 students took the post-survey. Students who did not complete both the pre- and post-surveys were excluded from the final data set. Prior to the project based learning, the students got an average of 4.69 questions on the pre-test correct and after the project was complete the students got an average of 4.97 questions correct out of eight questions. 75% of the students stated that overall they enjoyed the project.  

CONCLUSIONS: Developing skills in the fields of science, technology, engineering and mathematics is increasingly important for a student’s success in their future careers. This project has shown students how to complete an outbreak investigation from start to finish and taught them the roles of a local epidemiologist.
