Abstract
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 workforce development and enhance the industry's public image.Entities:

Representative statements from students and teachers for themes related to program effects on knowledge, awareness, and interest.
| Students | “There wasn't much I understood at the beginning of the module learning. I understand a lot more now.” |
| “As I have been doing this program my knowledge about poultry is much greater, and I am more confident when it comes to talking about poultry.” | |
| Students | “I am confident in my new ability to understand poultry terms.” |
| “I feel more confident talking about poultry because I have learned a lot about chickens and how to maintain them.” | |
| Students | “I have wanted to learn more because I found the poultry modules interesting.” |
| “I have started to want to learn more about poultry through each module.” | |
| “It has intrigued me and I have learned a lot more about chickens than I ever thought before.” | |
| Students | “They were not valuable at all because I had no interest in learning about poultry.” |
| “The games are not fun or engaging unless you already care about poultry.” | |
| “It is just hard for me to enjoy because I don't want to get a career in poultry.” | |
| Teachers | “I believe students need to have a basic animal science knowledge base to appreciate the modules.” |
| Students | “It showed me how much effort it takes to raise a flock, it makes me have more respect for this field of work.” |
| “There's so much more to something that I thought was so simple.” | |
| Students | “I now understand how many job opportunities there are in poultry.” |
| “It taught me about how people do these jobs and why they are actually very important.” | |
| Teachers | “As far as from a career standpoint, one thing—one of my students made the comment, she says, “I didn”t know there was that many jobs. I didn't know there was that many different things to it.' … It was a little bit of an eye opener on just what all is involved versus what they have as a mindset.” |
| Students | “I felt like I was actually there with the chickens and I found it really fun.” |
| “They had an interactive part to them which helped me be intrigued with the topic.” | |
| “They made things about chickens easier to understand.” | |
| “It taught us how to care for chickens in a real-life and visible way.” | |
| Teachers | “It also needs a project (hands-on activity) to go with it to reaffirm what they just learned.” |
| “More interactive, more things that interest the students. Like hatching eggs, learning to candle. They need more hands on in order to learn.” | |
