Langley will be training to be a pastry chef. The process will be difficult because it is so complex. Pastry requires just the right amount of handling to be perfect. Fillings can have a multitude of ingredients. And presentation is very important. Briefly describe the training techniques can be used to facilitate enactive mastery of these tasks.

There are basically three techniques for facilitating mastery: segmenting tasks, shaping behavior, and setting proximal goals. Task segmentation involves breaking the complex task into smaller or simpler components that can be taught individually and in order-like learning to make perfect pastry before ever making a pie. Shaping includes rewarding closer and closer approximations to desired behavior-reward Langley as his pastry gets closer to being perfect. The setting of proximal goals also increases mastery perceptions. One proximal goal could be to bake as perfect as possible piecrusts for custard pies. Students' answers may vary, but at the very least they should define each of the three techniques.
