What is a key reason for the limit of practice time in student improvement?

The key reason for the limit of practice time in student improvement is centered around the changes in cognitive strategies and physiological factors. As students practice, their brains develop new pathways for motor skills, which can lead to improved performance. However, there are diminishing returns on practice due to cognitive overload and fatigue. When practice sessions are too long, learners may become mentally fatigued, which can hinder their ability to absorb new information and make necessary adjustments in their technique.

Additionally, physiological factors play a significant role. Muscles and neural pathways can only adapt so quickly; excessive practice without adequate rest can lead to physical fatigue and decreased performance. Thus, finding the right balance in practice time is critical for maximizing improvement and preventing burnout or injury, instead of simply extending practice duration without mindful structure.

This understanding emphasizes the importance of quality over quantity in practice sessions, reinforcing that improvement is not solely a function of hours spent practicing.
