Scaffolding STEM Literacy Assignments To Build Greater Competence in Microbiology Courses.

Abstract

Different approaches can be used to impart science, technology, engineering, and math (STEM) literacy among undergraduates and thus can be modified to support various scientific concepts and course objectives. In comparable microbiology-related courses, scaffolded assignments to improve STEM literacy through data, information, and communication analysis skills were developed using the ASM Curriculum Guidelines and the Microbiology Course Inventory (MCI) to structure the course and assignments. Examples of such assignments included a meta-analysis using literature and bioinformatics, as well as a public data presentation and an epidemiological model based on current events. To evaluate the effectiveness of such approaches, assignment components were aligned to determine whether the activities reinforced the MCI concepts. Comparison of pre- and postcourse data indicated relative strengths (and weaknesses) addressed by scaffolded STEM literacy pedagogy. These efforts also contribute to a department-wide initiative to enhance career readiness and implementation of course assessments. Future goals are to broaden the integration of assignment components to other microbiology-related courses and have longitudinal assessment.
