The coronavirus disease of 2019 (COVID-19) pandemic makes it vital for nursing students to have access to online education. Dale Carnegie's principles were used as a teaching strategy by the same instructor in one of the two text-based online asynchronous courses on nursing informatics in the summers of 2020 and 2021. Students (n = 108) were randomly divided into two different sessions. Students' final grades and feedback to surveys on course and faculty at the end of the semester were collected and analyzed. Students' final grades and ratings on the course and faculty evaluation surveys in the intervention group that incorporated Carnegie's principles were higher than those in the control group. There were more positive and fewer negative comments in the intervention group than in the control group in both surveys. A positive learning environment created by Carnegie's principles helps instructors increase students' satisfaction and learning outcomes during stressful times.
