QMRA Wiki: An educational tool for interdisciplinary teaching of risk modeling in engineering curriculums

Quantitative microbial risk assessment (QMRA) is a paradigm that has demonstrated itself as a valuable tool in assessing the efficacy of engineering interventions through modeling and data analysis. One of the values of the QMRA paradigm is that in building the exposure scenario or conceptual model, the engineer understands their system better and can also predict changes to the system. The challenge in teaching QMRA to undergraduate and graduate engineering students is that QMRA is an interdisciplinary field that requires transdisciplinary approaches. What this means for QMRA instruction, is that the faculty member is faced with the formidable challenge of conveying essential concepts and guided implementation of the paradigm. This includes critical information from the fields of: microbiology, mathematics, physics, statistics, public health and engineering. Considering the need to broaden the QMRA community and include more engineers in the field, a tool for learning – the QMRA Wiki (qmrawiki.canr.msu.edu) - was developed. It serves as an online location for a suite of educational material, tools, applications, data and models. We will present the development of the wiki as an educational tool and focus on studies conducted over several years to ascertain the effectiveness of the QMRA wiki for education. A diverse group of participants in an instructional institute during the summers of 2015 and 2016 served as the cohort for this study. Through pre- and post- surveys, it was possible to determine their improvement in concepts related to QMRA data, models and peripheral material. The surveys are constructed to ascertain their comfort and ability to apply QMRA knowledge as well as the mechanics of QMRA before and after the institute. These results are being used to advance the QMRA wiki further and improve the educational tools.
