What is the Learning Curve A graphical representation

What is the Learning Curve ? • A graphical representation of how an increase in learning (measured on the vertical axis) comes from greater experience (the horizontal axis.

y Learning experience X

What is the Learning Curve ? • recording the success over a number of trials. presents diagrams of learning against trial number.

What is the Learning Curve ? • is a concept that graphically depicts the relationship between independent variable and dependent variable over a defined period of time.

What is the Learning Curve ? • is the representation in graph form of the rate of learning something over time. • Provides a way to show a subject’s learnability.

Notice … • We can draw a Learning curve for a single subject or a learning curve for a group of subjects showing how learning improves with experience. Con.

Learning Curve (1 / 2) • Whenever you delve into a new and very complex field your progress at the beginning of the learning curve is very slow.

Learning Curve (2 / 2) • This is mostly due to the fact that you first have to familiarize yourself with the topic, get an overview what’s going on, understand the basic definitions and terminology …. .

Different types of Learning curves 1. 2. 3. 4. Positive acceleration. Negative Acceleration. S-Shaped. Linear.

Positive Acceleration • Poor early performance improves later. but

Negative Acceleration • Good early performances but poorer performances in later trials.

S shaped • is a typical curve of learning of a gross motor skill : learning is slow to start with he/she gets to grips with the skill, then the learner begins to be motivated by success and to practice more hen ce a rapid improvement, and finally, improvement slow down as difficulties are encountered requiring more cognitive effort.

Little improvement Rapid improvement Learning plateau

Linear • Performance is directly proportional to the number of practice trials.

Plateau of Learning

Plateau of Learning • When a skill is learnt, initially rapid progress is made by the learner, however, after some time the progress is stopped and no amount of training makes any improvement. This, stage is called “plateau of learning”. • Not much change if at all in performance over a number of trials.

Causes of Plateau • • • Lack of concentration. Toughness of the skill. Poor coaching or training. Environmental pollution. Boredom. Less interest. Practice under poor conditions. Perfectionism. Overstress and tensions.

To avoid plateau… advices for Teacher Give new goals that can be reached. Give praise that is deserved. Ensure that there are regular rest intervals. Maintain motivation and employ positive cognitive techniques. • Vary and re-establish physical fitness. • Look at technical development for possible variations or improvements. • •
