Answer:
While any performance by a learner might be considered a performance task (e.g., tying a shoe or drawing a picture), it is useful to distinguish between the application of specific and discrete skills (e.g., dribbling a basketball) from genuine performance in context (e.g., playing the game of basketball in which dribbling is one of many applied skills). Thus, when I use the term performance tasks, I am referring to more complex and authentic performances.
