Learning involves facing challenges, struggling with difficult concepts, and making mistakes. In this presentation, I will discuss how I support the adoption of a growth mindset in my upper and lower division chemistry courses with educational technology, classroom practices, and frequent, consistent messaging. In particular, I will discuss my use of pre-lecture videos, iClicker questions (practice and review), multiple low-stakes assessments, Piazza, and Gradescope and Canvas rubrics. My goal is to normalize the challenge of learning difficult concepts, and motivate students to keep practicing and use mistakes as learning opportunities. I will also share the positive feedback I received from a preliminary survey about growth mindset in an upper division Physical Chemistry course, and from comments in the course evaluations of other courses.
