Final answer:
Dr. Deci's self-determination theory posits that feedback enhances motivation by affirming competence, which boosts an individual's intrinsic motivation. Effective feedback supports their personal growth, sense of autonomy, and belief in their abilities.
Step-by-step explanation:
According to Dr. Edward L. Deci's self-determination theory, feedback boosts motivation by supporting competence. Feedback that acknowledges a student's abilities and progress can enhance their intrinsic motivation, which arises from internal factors like personal growth and satisfaction. This differs from extrinsic motivation, which is driven by external rewards like money or praise. When feedback is used effectively, it can reinforce an individual's sense of competence and self-efficacy, which is their belief in their own capabilities to complete tasks.
Therefore, the impact of feedback on motivation can be seen as nurturing the intrinsic motivation essential for personal and educational growth.
It's important to recognize that intrinsic motivation can be undermined by the overjustification effect, where the introduction of extrinsic rewards for activities that one initially finds enjoyable for their sake can lead to a decrease in intrinsic interest.
However, if feedback is given in a way that supports autonomy, relatedness, and competence, without overemphasizing extrinsic rewards, it can positively impact motivation. This is seen when verbal praise, for example, aligns with internal goals and values, enhancing the intrinsic motivation to engage in a behavior or task.
