It could signal that the learner has reached a limit in their ability or that a transition may be occurring. This could be described as a plateau, where the individual is no longer progressing. Progression levels off as the learner obtain full proficiency. This describes a situation where the task may be easy to learn and progression of learning is initially fast and rapid. The rate of progression increases rapidly at the beginning and then decreases over time. Here are four common types of a learning curve and what they mean: 1. Many factors can impact the end-results, resulting in a variety of different learning curve shapes. The formula can be used to predict a learner’s rate of learning of a simple task or even help businesses to predict the production rate of a product.įor a more detailed look at how to use this formula.Īlthough the theory states that more attempts = a decrease in time, it does not always work out that way. The formula stipulates that the more attempts that are included, the more the overall time will decrease. The formula can be used as a prediction tool to forecast future performance. X represents the total amount of attempts completed Y is the average time over the measured durationĪ represents the time to complete the task the first time The original model uses the formula: Y = a X b The theory can also be expressed as a mathematical function that can be used as a prediction tool. If one were to plot the repeated attempts of a learner against the time taken to complete the attempt, a pattern can be identified indicating that the task takes less time as the learner gains more experience via repeated attempts. The experience curve theory states that the effort to complete a task should take less time and effort the more the task is done over time. There are currently different variations of the original formula used today in specialized applications, but the idea remains familiar to the original formula. Wright in 1936 in his work " Factors Affecting the Cost of Airplanes", after realizing that the cost of aircraft production decreased with the increase in production performance. This is the basis for the learning curve formula, the “ Cumulative Average Model” (or “Wright’s Model”), which was described by T.P. The 2nd illustrates an eliminative, or declining, curve of time needed to perform the same task.Įliminative curve of time - “General experimental psychology” (Bills, Arthur Gilbert, in 1934, page 194) Wright’s experience curve The 1st curve of achievement represents an increase in productivity over each unit of trial.Īcqusitive curve of amount - “General experimental psychology” (Bills, Arthur Gilbert, in 1934, page 193) He described two sides of the same process and had presented two learning curve graphs. In his work, he describes it saying, “the learning curve is a graphical device for picturing the rate of improvement in terms of a given criterion of efficiency, as a result of practice.” Later, Arthur Bills described the learning curve in his work “ General experimental psychology” (Bills, Arthur Gilbert, in 1934, page 192). Nowadays it helps us understand when and why we forget certain information and how we can tackle this. The modern Microlearning theory is based on Ebbinghaus memory studies. This theory helps us to understand how our memory works, and retains information, relating to specific things people attempt to learn. He mostly was focusing on memory studies and developed a forgetting curve theory. Hermann Ebbinghaus described this theory as early as 1885. While the term "learning curve" came into use in the early 20th century, Dr. The Learning Curve Theory Ebbinghaus' forgetting curve Graphical correlation between a learner's performance on a task and the number of attempts or time required to complete the task. The learning curve theory proposes that a learner’s efficiency in a task improves over time the more the learner performs the task. Emotional intelligence in the workplaceĪ learning curve is a correlation between a learner's performance on a task and the number of attempts or time required to complete the task this can be represented as a direct proportion on a graph.
