The objective of this study was to survey student perceptions of mastery of learning outcomes in the 100% online asynchronous course Nutritional Management taught at the University of Florida. There are many ways to perceive if students have mastered learning outcomes in a course. Quizzes are one way to measure if students understand concepts and terminology. However, in online courses there is the concern that students may ‘cheat’ and a quiz is not an effective measure of student achievement. Online instructors need to look for other assessments, like assignments that ask students to apply what they have learned to solve a problem. This is easy to measure in-person classrooms and laboratories but more challenging online. This study conducted a mid-term survey to students in the spring 2025 offering of Nutritional Management. The survey asked students about their perceived learning and mastery of course learning outcomes based on two quizzes and two authentic challenge assignments. This study was deemed IRB exempt.
