A "learning curve" is a graphical representation that shows how a person's performance improves over time as they gain experience with a task or skill. Initially, progress may be slow, but as individuals practice and learn, their efficiency and effectiveness typically increase. This concept is often used in education and training to illustrate how quickly someone can master new information or abilities. The shape of a learning curve can vary depending on the complexity of the task and the individual's prior knowledge. For example, a steep learning curve indicates rapid improvement, while a gradual curve suggests that learning may take more time. Understanding learning curves can help educators and trainers design effective programs to enhance skill acquisition and retention.
