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.

课堂上的家禽：基于家禽科学的在线教育计划对高中 STEM 教学的有效性。

家禽行业的公众知识有限，但对该行业的态度会影响消费者行为并影响家禽职业和未来研究的吸引力。本研究评估了一项在线学习计划，该计划将家禽科学中的 STEM 学习情境化，旨在增加家禽知识和兴趣。印第安纳州 16 个班级（n = 12 名教师）的高中生参与者（n = 169）在 2018 年秋季学期完成了七个 30 分钟的在线模块。本案例研究使用了混合方法、顺序解释设计。学生对家禽的知识和兴趣以及教师对该计划的看法使用定量方法进行了检查。研究' 定性部分评估了对学习体验的看法，包括开放式学生和教师调查问题以及教师焦点小组。定性数据表明，学生的家禽知识，包括对行业和相关职业的认识，在学习模块后得到了提高。配对 t 检验显示，每个模块后内容测验分数的增加有中到大的影响大小（P < 0.001，Cohen's d = 0.45 到 0.80）。学生对家禽的平均兴趣最初很低，并且在完成该计划后保持统计相似（M = 1.84, 1.87; p = 0.67）。学生和教师的陈述表明，该项目的设计特点增强了一些学生的兴趣。其他学生不认为该计划及其家禽科学主题有趣或与他们的生活相关。这项研究的结果可用于为创建有效的家禽学习资源提供信息，以促进劳动力发展和提升行业的公众形象。
