Steffi and Emily work at Education Yours, a nonprofit educational institution. Last month, Steffi, newly hired on a temporary teaching assignment, was asked to teach an online course. Being new to online teaching, Steffi talks with Emily and several individuals who have been teaching online for several years. Emily discusses the pride she takes in her teaching and says she always approaches her teaching with total enthusiasm. She also expresses her belief that exerting a high level of effort will result in a successful performance for Steffi in her online teaching. Emily's self-efficacy source appears to be:
