This study examined undergraduate and graduate students' perceptions of the impact of in-class learning activities, out-of-class learning activities, and instructional materials on their learning. Using survey methodology, students anonymously assessed their perceptions of in-class activities, out-of-class activities, and instructional materials as most impactful, helpful, and enjoyable to their learning. Undergraduate college students found Jeopardy games, PowerPoint slides, and checking for understanding/review questions to be most helpful, while 50% often perceived Jeopardy games, Poll Everywhere, videos, and PowerPoint slides as enjoyable active learning strategies. Graduate students perceived small groups, out-of-class writing assignments, and Lino as most helpful to their learning. Additionally, an analysis of student comments about why these strategies were impactful, helpful, and enjoyable revealed 4 themes: fun, learning collaboratively, challenging but helpful, and variety in how students learn. Creating a learner-centered environment that is engaging as well as enjoyable for students positively impacts perceptions of students' learning, which should encourage teachers to adopt this approach in their own college classrooms.
