Agree. A common theme in the science of learning is that effective learning centers on deliberate practice, where activities are done entirely for the purpose of pushing one's limits and improving performance. Of course, these activities tend to be more effortful and less enjoyable. Classroom activities that are enjoyable, collaborative, and non-repetitive (such as group discussions) can sometimes be useful for increasing student motivation and softening the discomfort associated with deliberate practice. However, these activities are only supplements, not substitutes, for deliberate practice. Unlike deliberate practice, they do not directly move the needle on student performance – rather, they "grease the wheels" and reduce psychological friction during the process of deliberate practice.
