Learning curve and Learning Plateaus

The document discusses the concept of learning curves, which are graphical representations of the learning process indicating proficiency over time through various types including straight line, negative accelerated, positively accelerated, and combination curves. It also covers learning plateaus, periods of stagnation in learning, their causes, and suggestions on how to overcome them. Additionally, it highlights the benefits of understanding learning curves for teachers in adapting their instructional methods and supporting student progress.

CONTENT  Learning Curves  Different types of learning curves  Characteristics of a learning curves  Uses of learning curve
LEARNING CURVES  A learning curve is a graphical representation of how learning takes place in a particular situation.  It is a graph plotting the course of learning in which X-axis represents some measures of practice , units of time , number of trails while Y-axis plots a measure of proficiency or accomplishment , material retained ,puzzles solved etc.  A learning curve depicts the rate of improvement in various learning situation.
DIFFERENT TYPES OF LEARNING CURVES  Straight line learning curve.  Negative accelerated learning curve or Convex curve.  Positively accelerated learning curve or Concave curve.  Combination type of curve or concave – convex curve.
STRAIGHT LINE LEARNING CURVE  Such a curve shows a constant or uniform rate of progress in learning.  Performance is directly proportional to the number of practice trials
NEGATIVE ACCELERATED LEARNING CURVE OR CONVEX CURVE.  It is a negatively accelerated curve which shows rapid initial improvement in learning that shows down with time.  Good early performance but poorer performances in later trials
POSITIVELY ACCELERATED LEARNING CURVE OR CONCAVE CURVE  It is positively accelerated curve which shows slow initial improvement in learning that increases with time ultimately learning towards the mastery over the learning material.
COMBINATION TYPE OF CURVE OR CONCAVE – CONVEX CURVE.  It is a S – Shaped learning curve forming by the combination of a concave and convex curve depending on rapid or slow initial success followed by a reverse condition in learning.
LEARNING PLATEAUS  Defining the term plateau , Woodworth and Marquis – “ Along flat stretch in the learning curve , a long period of almost no improvement , picturesquely called a plateau, provided it is followed by more improvement.  A plateau in the learning curve represents a stationary stage where apparently no progress in the learning is recorded
CAUSES OF LEARNING PLATEAU  Poor or faulty method of teaching  Physical as well as mental fatigue  Lack of proper motivation  Too much difficulty and complexity of the task  Conflict of previous learning with new learning  Mental or physical illness  Poor and unfavorable environment for learning  Lack of attention
ELIMINATION OF LEARNING PLATEAU  Adopting effective methods of teaching  Acquainting the learner with clear – cut goals or aims of the work in hand  Arousing and maintaining interest in learning  Arranging learning material according to the increasing level of difficulty or complexity  Suggesting the learner to discontinue for the time being when a period of no improvement is reached  Minimizing the distracting factors present in the learning environment  Providing sufficient motivation and incentive
CHARACTERISTICS OF A LEARNING CURVES  A learning curve have the unique characteristics or initial improvement no matter whether it is rapid or slow till a somewhat uniform rate of improvement is achieved.  In the learning curve we rarely find a straight line path ( there must be various ups and downs)  The final stage in the learning curve is reached when one reaches to a point beyond which little learning or say no learning takes place after repeated trails or continuous practice
CHARACTERISTICS OF A LEARNING CURVES  In the beginning and end there comes a stage or stages in learning where there seems to be no growth or improvement . It is stationary stage or plateau (flat portion ) in a learning curve.  After passing the stationary stage or plateau the learning curve again shows some improvement and with some ups and downs advances towards the point of maximum learning
USES OF LEARNING CURVE Learning curve help teacher  Acquaint himself with the individual differences in learning among his students  To improve the methods of teaching  Provides the opportunity of self appraisal  To understand the emotional life and other personality characteristics of the leaner  Helps to select appropriate teaching aids.  Helps to maintain proper account of the regular progress of the students.  Helps to compare the progress of students
