In another exciting episode of What's New in APE, we interviewed Lindsey Nowland (@LindseyNowland), a PhD candidate from Old Dominion University, about her research expertise in adapted physical education (APE), particularly focusing on self-efficacy when teaching students with disabilities in PE settings. Lindsay shares her journey into this field, highlighting her experiences and her transition from general physical education to APE. Further, we talk about the importance of self-efficacy in PE teachers, specifically exploring the four sources of self-efficacy: mastery experiences, vicarious experiences, social persuasion, and physiological responses. Ms. Nowland emphasizes the need to measure these sources more comprehensively in research to better understand how they impact PE teachers' beliefs and confidence.
