Final answer:
Experts mean that learning can occur without being immediately evident when they say "learning is invisible." Indicators of motor skill proficiency include accuracy, speed, and efficiency of movement, reflecting the unseen process of skill learning and internalization.
Step-by-step explanation:
When experts say that "learning is invisible," they are referring to the process of acquiring knowledge or skills without the learning being immediately apparent. This concept includes forms of learning such as latent learning and implicit procedural memory, where individuals learn by experience or observation without an immediate change in behavior.
Three commonly used indicators of a person's level of proficiency at a motor skill are:
- Accuracy and precision of the movements.
- The amount of time it takes to complete a motor task.
- The smoothness and efficiency of the skill execution.
These indicators can demonstrate how well a person has learned and internalized a motor skill. The improvement in these areas is often a result of the learning process that has taken place over time, even though this process itself was not directly observable.
