There is opportunity to decrease the frequency of foodborne illnesses by improving food safety competencies and planned behaviors of college students before they begin careers in the food industry. The objectives of this study were to (1) develop a multimedia case study teaching method that provides real world context for food science education; and (2) evaluate the extent to which it improves the intentions of students to implement food safety management systems upon entering the workforce, as well its impact on knowledge gains and students’ abilities to understand complex concepts. The target audience consisted of all participants in an upper‐level undergraduate food safety management systems course (n = 17). A pretest and posttest survey research instrument was developed to measure knowledge gains and also students’ food safety intentions using the framework of the Theory of Planned Behavior. Students experienced significant gains in knowledge, attitude, and intention after completion of the course (P < 0.05). One hundred percent of students agreed that the interactive videos aided in their understanding of food safety concepts. A paired t test suggested that both behavioral control beliefs and attitudes of students toward food safety management significantly increased (P < 0.5) after completion of the case study. These results suggest that integrating multimedia case studies into food science education may enhance food safety behaviors.

基于现实的多媒体案例研究教学方法的开发及其对学生计划食品安全行为的影响

有机会通过提高食品安全能力和大学生在食品行业开始职业生涯之前的计划行为来减少食源性疾病的发生。这项研究的目的是(1)开发一种多媒体案例研究教学方法,为食品科学教育提供真实的环境;(2)评估在加入劳动力队伍后,它在多大程度上改善了学生实施食品安全管理体系的意图,以及它对知识获取和学生理解复杂概念的能力的影响。目标受众包括食品安全管理系统高级课程的所有参与者(n = 17)。开发了一种前测和后测调查研究工具,以使用计划行为理论的框架来衡量知识获取以及学生的食品安全意图。完成课程后,学生会在知识,态度和意图方面获得明显的收获(P <0.05)。百分之一百的学生同意互动视频有助于他们对食品安全概念的理解。配对t检验表明,案例研究完成后,行为控制信念和学生对食品安全管理的态度均显着提高(P <0.5)。这些结果表明,将多媒体案例研究纳入食品科学教育可以增强食品安全行为。完成课程后的态度和意愿(P <0.05)。百分之一百的学生同意互动视频有助于他们对食品安全概念的理解。配对t检验表明,案例研究完成后,行为控制信念和学生对食品安全管理的态度均显着提高(P <0.5)。这些结果表明,将多媒体案例研究纳入食品科学教育可以增强食品安全行为。完成课程后的态度和意愿(P <0.05)。百分之一百的学生同意互动视频有助于他们对食品安全概念的理解。配对t检验表明,案例研究完成后,行为控制信念和学生对食品安全管理的态度均显着提高(P <0.5)。这些结果表明,将多媒体案例研究纳入食品科学教育可以增强食品安全行为。5)完成案例研究后。这些结果表明,将多媒体案例研究纳入食品科学教育可以增强食品安全行为。5)完成案例研究后。这些结果表明,将多媒体案例研究纳入食品科学教育可增强食品安全行为。
