Pre/post-Test Evaluations of Agricultural Biosecurity Curriculum

Abstract

ABSTRACT Objective In this combined study, the efficacy of different educational methods in enhancing students’ agricultural biosecurity knowledge, which is vital for public health, food security, and agricultural safety, was assessed. Methods In-person and virtual learning methods, utilizing educational content developed for the Gearing Up for Safety program, were investigated with 692 total participants. In the in-person learning method, 459 students aged 12–20 received a 50-minute in-person training session using the Gearing Up for Safety lesson on agricultural biosecurity. A 20 question pre- and post-test gauged knowledge gain. In the virtual learning method, 223 students, aged 12–20 received two, 40-minute virtual training sessions using the same content. Results Results of knowledge gain from the in-person method improved significantly from 55% to 77% (t(458) = -22.37, P < .001). Chi-squared analysis showed 19 out of the 20 questions significantly contributed to learning. Results of knowledge gain from the virtual method also showed a notable knowledge gain increase from 53% to 66% (t(222) = -11.86,  P< .001). However, a chi-squared analysis revealed that only 10 of the 20 questions significantly contributed to learning. In-person learning effectively supported better understanding of general biosecurity. Conclusions Virtual education improved general understanding but required enhanced focus on topics like vaccination, pest management, and community biosecurity preparation for comprehensive knowledge. Both in-person and virtual learning resulted in an increase in agricultural biosecurity knowledge, with in-person learning exhibiting a higher proportion of significant knowledge gains. These findings emphasize the importance of diverse educational methods in preparing future agricultural workers to ensure safety and health in agricultural settings. Results were used to enhance the curricula content being made available as part of the Gearing Up for Safety program for young and beginning workers.
