This chapter discusses theories of motivation and how to apply them in classroom settings. It covers Maslow's hierarchy of needs, attribution theory, expectancy theory, goal orientation theory and more. The key implications for teachers are to give students feedback that builds self-efficacy, set appropriately challenging tasks, emphasize learning over performance goals, and use praise strategically to reinforce effort rather than ability. Fostering an environment where students feel capable and supported can enhance their motivation to learn.
