Poultry in the classroom: effectiveness of an online poultry-science-based education program for high school STEM instruction

摘要

Public knowledge of the poultry industry is limited, yet attitudes towards the industry shape consumer behavior and influence the attractiveness of poultry careers and future study. This study assessed an online learning program contextualizing STEM learning within poultry science which was designed to increase poultry knowledge and interest. High school student participants (n = 169) across 16 classes (n = 12 teachers) in Indiana completed seven 30-min online modules during the fall 2018 semester. This case study used a mixed-methods, sequential explanatory design. Student knowledge and interest in poultry and teacher perceptions of the program were examined using quantitative measures. The study's qualitative portion assessed perceptions of the learning experience and comprised open-ended student and teacher survey questions and a teacher focus group. Qualitative data suggested that students' poultry knowledge, including awareness of the industry and related careers, was improved following the modules. Paired t-tests showed moderate to large effect sizes regarding increases in content quiz scores following each module (P < 0.001, Cohen's d = 0.45 to 0.80). Students' mean interest in poultry was initially low and remained statistically similar upon completion of the program (M = 1.84, 1.87; p = 0.67). Student and teacher statements indicated that design features of the program enhanced interest for some students. Other students did not perceive the program and its poultry science topics to be interesting or relevant to their lives. Results from this study can be used to inform the creation of effective poultry learning resources to contribute to work-force development and enhance the industry's public image.
