486 - Comparison Between Online and In-person Instruction in a Laboratory-based Animal Science Course

Online teaching has been rapidly integrated into laboratory-based learning environments across all disciplines due to the 2019 pandemic. With such an abrupt transition to online instruction, the quality of traditional instruction in laboratory-based courses is in question. The objective of this study was to determine if a hands-on laboratory could be effectively taught online. This study compared the academic achievement and perception of students (n = 163) in an Introduction to Animal Science course where half the course instruction was online, and half was in-person. Student achievement was measured from weekly quizzes, and two major exams, a midterm and final, testing material covered online and in-person, respectively. All statistics were analyzed using JMP Pro 14. Exam scores were correlated to quiz scores to assess output to input, and were strongly correlated. A 10% increase in quiz performance resulted in a 1% increase in exam performance for both types of instruction (P < 0.01). There is no difference in this effect between material delivered online, and in-person. The efficacy of the method of instruction was measured by student surveys. Meeting style preference of students was different between instruction methods, where student preference shifted from asynchronous (40% to 11.6%) to hybrid instruction (39.6% to 69.5%), with no change in virtual preference (P < 0.01; P = 0.14). Student perception of quiz and exam question fairness was different where students thought question fairness increased between online and in-person instruction for quizzes and exams, respectively (P < 0.01; P < 0.01). In conclusion, there are no differences in student performance based on grades between online and in-person instruction; however, student perception of meeting style and assessment question fairness improved when students were taught in-person. As a result, laboratory-based science courses can be successfully transitioned to online instruction.
