As students gain facility with a new skill or new knowledge, they tend to need less guidance and more time to consolidate (or strengthen) their new knowledge with additional practice. Since they are less likely to encounter mistakes or problems at this point, they begin to benefit from independent practice -- opportunities to review and repeat their knowledge at their own pace and with fewer interruptions. At this point, therefore, guided practice may feel less like help than like an interruption, even if it is well-intentioned. A student who already knows how to use a new computer program, for example, may be frustrated by waiting for the teacher to explain each step of the program individually. If a student is already skillful at translating Spanish sentences into English in a language class, it can be annoying for the teacher to “help” by pointing out minor errors that the student is likely to catch for herself.
By definition, the purpose of independent practice is to provide more self-regulation of learning than what comes from guided practice. It implies a different message for students than what is conveyed by guided practice, a message that goes beyond the earlier one: that it is now time to take more complete responsibility for own learning. When all goes well, independent practice is the eventual outcome of the zone of proximal development created during the earlier phase of guided practice described above: the student can now do on his or her own, what originally required assistance from someone else. Or stated differently, independent practice is a way of encouraging self-determination about learning, in the sense that we discussed this idea in Chapter 6. In order to work independently, a student must set his or her own direction and monitor his or her own success; by definition, no one can do this for the student.
