Explanation:

Knowledge of performance is feedback related to the way in which a specific skill is performed. It gives feedback on the quality of execution of the skill and may come from either intrinsic or extrinsic sources. An example of this is a comment from the coach about the foot placement during a kick in soccer, or noticing the height of a ball during a tennis serve.

Knowledge of results refers to how successfully a skill is performed. It is always external feedback and may come from sources such as a coach, spectators or teammates. Examples of knowledge of results may be how many goals were scored per number of attempts, or what distance was covered in javelin. The athlete can use this feedback to execute a skill differently in order to achieve different results.
