No matter how old we are or how long we've been learning, feedback is essential to growth. When non-verbals are the only response we receive, it can be tough to make a solid assessment of our personal progress. A gentle nod, a kind smile, and a pat on the back go a long way. Without explicit feedback, we are left guessing whether or not we hit the target. Some scenarios do not allow for instant evaluation, and the learner must wait days, weeks, or even months to find out their performance results. This type of feedback prevents the learner from making mid-course corrections, and the individual is left wondering whether he or she had the skills needed for the job. Timely feedback is helpful, but it's not always doable. Sometimes learners have to wait to find out how they performed. In the meantime, they keep plowing ahead, honing their practice, and solving interesting problems. Learning is inherently risky, and we must accept our approximations. We aren't always going to hit the target on our first attempt, but we must be willing try.
