What is a Learning Curve?
A learning curve is a concept used to measure how quickly a skill can be mastered. Usually shown as a simple graph, a learning curve often depicts the combination of the time it takes to learn a new idea or skill set, combined with the rate at which mastery is achieved. Learning curves are often used to measure an individual’s progress against an average.
German psychologist Hermann Ebbinghaus coined the term during his research on memory and memorization in the late 19th century. In his 1885 work, Memory: A Contribution to Experimental Psychology, Ebbinghaus described his findings regarding both the learning curve, or rate at which knowledge is gained, and the forgetting curve, a related graph that measures how quickly memorized information is lost. His book is considered a groundbreaking work in the field, and quickly led to the popularity of using learning curves as a means of measuring progress.
The concept is somewhat confusing in terminology, even to experts. For instance, a steep learning curve implies two very different graphs. Some believe that , a steep curve means there is a large gain of knowledge in the early stages, displayed on the usual graph as a steep incline at the beginning that gradually tapers out Chess, for instance, might be considered a game with a steep learning curve, for while the rules are simple and quickly learned, mastery over the game may take years. The term is also sometimes used to describe a particularly difficult or arduous skill to learn, as steep slopes are presumably harder to climb.
Flat or gradual learning curves are more generally understood as a concept. On a flat curve, the rate of knowledge gained is slowly spaced out over time, so the rate is generally the same. Flat curve subjects take a long time to gain complete mastery over, but provide ample time to truly imprint the procedures or skill components on the brain. Subjects with a gradual or flat curve are often very difficult to learn, as they do not provide the rewards of quick, usable knowledge.
It should be remembered that learning curve graphs are representational of an average rate of knowledge gained over time. As different people have different backgrounds or aptitudes, some may learn considerably faster or slower than others. Yet consistent failure to meet goals or checkpoints established by learning curves may indicate a problem, such as a learning disability or simply misunderstanding the fundamentals of a subject. In this case, remedial tutoring in the subject may be worth trying to correct the issue. If tutoring fails to help improve your rate of learning, consider being tested for learning disabilities, such as dyslexia, which may be impeding your ability to keep up with the curve.
