THE CONCEPT OF LEARNING CURVE


Learning curve is a term commonly used to determine how long it takes for a learner to acquire a knowledge, attitude, or motor skill. To understand the learning curve concept as it relates to the process of teaching and learning. One must refer to educational psychology literature. The learning curve has been described as basically nothing more than a graphic depiction of changes in performance or output during a specified time period (McCray 8t Blakemore, 1985). A learning curve shows the relationship between practice and performance of some type of a skill. It provides a concrete measure of the rate at which a person learns a task. Cronbach (I963) defined a learning curve specifically as it relates to psychomotor skill development as “a record of an individual's improvement made by measuring his ability at different stages of practice and plotting his scores" (p. 297).
According to Cronbach (I963), the learning curve theory is divided into six stages (see Figure 10-2):

  1. Negligible progress: This “pre—readiness" period is when the learner is not ready to perform the entire task, but learning is taking place, such as developing attention, manipulation, and perceptual skills. This period can be relatively long in young children who are developing physical and cognitive abilities and in older adults who may have difficulty in making key discriminations.
  2. Increasing Gain: Rapid gains in learning occur as the learner grasps the essentials of the task. Scores rise rapidly as the learner becomes aware of cues to attend to, goals to attain, or ways to effectively organize responses. Motivation to perform a skill increases when the learner has interest in the task,  receives approval from others or experiences a sense of pride in discovering the ability to perform.
  3. Decreasing gains: In this period the rate of improvement in mastering a task slows down and additional practice does not produce much, if any, gains. Learning occurs in smaller increments as the learner incorporates changes by using cues to smooth out performance.
  4. Plateau: No substantial gains are made. This “leveling of?’ period is characterized by a small rate of progress in performance. During this stage, the learner is making minor adjust-menu in mastering a skill. However, the belief that this is a “period of no progress" is considered false. Gains in skills can occur even though overall performance scores remain stable.
  5. Renewed gains: During this period, additional progress can be made after the plateau period has ended. If gains occur, they are usually due to growth in physical development, renewed interest in the task, a response to a challenge, or the drive for perfection.
  6. Approach to limit: Progress at this point becomes negligible. The ability to perform has reached its potential. The “limit” is a hypothetical stage only because there is never certainty that a learner cannot improve further.

Learning process is not always similar. There is more progress in sometimes, sometimes less and sometime absolutely nil. So, we cannot find out the rate of learning. But, psychologists have attempted to measure the progress in learning. They described the progress in learning by drawing a line on the graph paper. This line is curve, and not straight. So, it is called Learning curve.
The first person to describe the learning curve was Hermann Ebbinghaus in 1885. He found that the time required memorizing a nonsense syllable increased sharply as the number of syllables increased. Psychologist, Arthur Bills gave a more detailed description of learning curves in 1934. He also discussed the properties of different types of learning curves, such as negative acceleration, positive acceleration, plateaus.

DEFINITION
  • According to Skinner, a learning curve is a progress representation of person’s improvement or lack of improvement in a given activity.
  • Raimers et.al defined the learning curve as a method of partial learning of a given activity.
  • A learning curve is a graphical representation of how learning takes place in a particular situation – S.K.Mangal.
  • Learning curve refers to the graphical relationship between the amount of learning and the time it takes to learn.
In the learning curve there are two scales: horizontal and vertical. The horizontal scale is called x-axis and the vertical scale is called y-axis. For drawing the learning graphs we divided the horizontal scale (x-axis) into units of time or the numbers of trials required for learning and the vertical scale (y-axis) into units of achievement, material studied or problem solved, etc.

STAGES
Normally learning curve comprises of four stages.
  • Initial stage- It is also called lad phase. In lag phase the learning is merely zero for first few practices.
  • Steep up stage- This is the second stage. It is also called log or exponential phase. In this stage the learning is suddenly increased and rate of improvement is substantial.
  • Intermediate stage-
  • It is also called Stationary Phase. Now, there is no progress in learning or improvement is arrested. So, it is called Plateau. Skinner says ‘a plateau is a horizontal stretch indicative of apparent progress’. It places an important role in learning process because when such a stage is reached, a learning curve becomes almost flat.
Reasons for plateau in learning-
  • Poor or faulty method of learning.
  • Physical and mental fatigue or boredom
  • Too much difficulty or complexity of the learning material
  • Lack of proper motivation and loss of interest of the learner
  • Poor and unfavorable environment
  • Distraction and inattention of the learner
  • Satisfaction of the learner with moderate achievement
  • Final stage- This is the final stage. Here the learner has reach the maximum limit of the improvement.
 
Types of curves-
There are three types of learning curve based on the units which plotted.
  • Concave curve- This learning curve is also called positively accelerated curve. It depicts slow initial improvement in learning that increases with time leading towards the mastery of learning materials. At the initial the rate of progress may be slower, but at the final the learning rate increases noticeably. This learning curve is often occurring in the learning situation. Here the task may be new one or difficult one to the student at the beginning. But with the increasing practice he is mastery over that at the end.
  • Convex curve- This learning curve is also called negatively accelerated curve. It depicts rapid initial improvement in learning that decreases with time. At the initial the rate of progress maybe faster, but at the final the learning rate slows down noticeably. This learning curve is occurring in the learning situations where the task is simple or learner has had previous practice on a similar task.
  • Concave and convex curve- The third curve involves the combination of the first two concave and convex curves, is known as Concave-Convex Curve. It looks like an English letter ‘S’. So called S-shaped curve. In the beginning this is depending upon the nature of the learner, learning material and the learning environment. It is normally obtained where the situation the learner study the entire learning from zero performance to its mastery.
Characteristics of learning curve
  • There is an initial improvement whether it is slow or rapid.
  • No stage learning progress is uniform. There are various ups and downs (spurts) in the learning curve even a general acceleration is recorded.
  • In between the beginning and end of the learning curve, there is no improvement in learning is called plateau (flat or stationary stage).
  • At the final stage in the learning curve, we can find whether there is any little learning or no learning takes place.
  • After reaching the stationary stage or plateau the learning curve again shows some improvement with spurts.
Educational implications
  • The teacher should keep in his mind the individual differences of the learners.
  • The teacher has to choose or use proper method of teaching and techniques and environment by the guidance of the learning curves of his students.
  • The students may acquaint with their own progress in learning. It can give them the opportunity of self-appraisal.
  • The unusual spurt reveals about the fatigue, poor motivation, poor method of teaching and other personality characters of the learner. The teacher can make use of his knowledge in studying the behaviour of the student and eliminate the plateau.

Efficient methods creating interest, making aware of the goals, moving simple to complex, providing motivation, minimizing the distraction factors are used to eliminate the plateau.

Course: 103 Concept of Learning: formal, non-formal and informal learning


Concept of Learning

Meaning and Nature:

Learning is a key process in human behaviour. All living is learning. If we compare the simple, crude ways in which a child feels and behaves, with the complex modes of adult behaviour, his skills, habits, thought, sentiments and the like- we will know what difference learning has made to the individual.
The individual is constantly interacting with and influenced by the environment. This experience makes him to change or modify his behaviour in order to deal effectively with it. Therefore, learning is a change in behaviour, influenced by previous behaviour. As stated above the skills, knowledge, habits, attitudes, interests and other personality characteristics are all the result of learning.
Learning is defined as “any relatively permanent change in behaviour that occurs as a result of practice and experience”. This definition has three important elements.
a. Learning is a change in behaviour—better or worse.
b. It is a change that takes place through practice or experience, but changes due to growth or maturation are not learning.
c. This change in behaviour must be relatively permanent, and it must last a fairly long time.
All learning involves activities. These activities involve either physical or mental activities. They may be simple mental activities or complex, involving various muscles, bones, etc. So also the mental activities may be very simple involving one or two activities of mind or complex which involve higher mental activities.What activities are learned by the individual refer to types of learning. For example, habits, skills, facts, etc.
Learning is not a product, it’s a process. It prepares individual for any adjustments and adaptations in life. Learning is goal oriented or purposeful. Learning is universal and comprehensive process.

Formal learning:
Formal learning programs are typically synonymous with full-scale learning management systems (LMS), with courses and curricula mapped in a very structured way. As a result, content is generally created by a specified group of instructional designers and trainers.
Formal learning is planned learning that derives from activities within a structured learning setting. Content and learning materials can be delivered via a traditional class room training model, complete with lectures, required reading and scheduled testing. Live webinars and screen-sharing technology can also be used so that remote learners can attend the required sessions.
Learning typically provided by an education or training institution, structured (in terms of objectives, learning time or learning support) and leading to certification. Formal learning is intentional from the learners’ perspective.
Features of formal learning:
·         a prescribed learning framework
·         an organised learning event or package
·         the presence of a designated teacher or trainer
·         the award of a qualification or credit
·         the external specification of outcomes

Formal learning experiences are typically packaged as ‘courses’ or ‘programmes’. These tend to have a number of features in common:

Objectives that describe, in terms of knowledge, skills and attitudinal change, what learning is intended to result from successful completion of the course or programme. Some courses may adopt a more learner-centred approach, focusing on the goals of the learners themselves, but it would still be highly unlikely for a formal learning intervention to have no objectives at all, whether or not these are made explicit.

An established curriculum or learning plan, which sets out how the learning objectives are to be achieved in terms of the topics to be covered and/or the activities to be undertaken.

Content assembled by or with reference to acknowledged subject experts. At the very least this content is likely to consist of a simple trainer guide or lecture notes. More commonly, it will extend to slides, videos and other visual aids, handouts, job aids and reference books. And where self-study forms an important part of the intervention, the content could include workbooks, online reference materials, interactive tutorials and simulations.

A designated teacher, trainer or tutor to facilitate the learning process. The role of this person or persons will vary widely depending on the type of intervention and pedagogical approach, from a formal instructor to a subject expert, a coach, an assessor, a moderator or a curator. In cases where the intervention consists entirely of unsupported self-study, there will, of course, be no role at all.

Some form of assessment, to determine whether the learning objectives have been achieved. Where a qualification is being awarded, this assessment could be elaborate, requiring an exam, a practical assessment, or the formal submission of a paper or portfolio. In other cases, the process of assessment could be much less formal, perhaps a practical exercise or a quiz.

Non-formal learning:
Learning that is not provided by an education or training institution and typically does not lead to certification. It is, however, structured (in terms of learning objectives, learning time or learning support). Non-formal learning is intentional from the learner’s perspective.
Non-formal learning is a form of learning that takes place outside the parameters of the traditional learning structures or institutions. One could argue that ‘all’ learning that takes place outside organizations is, in fact, non-formal in character because it is not constrained by rules, ceremony or conventions. Non-formal learning is relatively systematic and (but not necessarily) pre-planned with an explicit intention on the part of both learner and mentor to accomplish a/some specific learning task(s). It is clear that non-formal learning involves some kind of guidance from a mentor. As this type of learning is voluntary, it is not like the compulsory education which is given at school (Morgan, 2000, p. 95).
Non-formal learning occurs when learners opt to acquire further knowledge or skill by studying voluntarily with a teacher who assists their self-determined interests, by using an organised curriculum, as is the case in many adult education courses and workshops.
Non-formal learning takes place outside the school organization or school system. It focuses on imparting vocational training to the student and is generally linked to vocational and functional literacy. i.e. each one teach one.
Characteristics of non-formal learning
It is an open-ended process of learning with lots of discussions, sharing, exploring, analysing, judging, etc.
1)      It is well planned.There may or may not be a definite course or curriculum.
2)      Time to complete might be flexible.Curriculum also might be flexible.
3)      Agencies such as the government, management, etc. are involved.
4)      There is mental strain on teacher and taught but not to the extent found in formal learning.
5)      There is no age limit or barrier to undergo non-formal learning.
6)      Exams may or may not be conducted at the end.Certificates, awards, may or may not be awarded at the end of the learning.
7)      It is a voluntary mode of learning. The student has the choice to take up what interests him.
8)      It is more practical and useful for day to day life than the theory based formal education.
9)      Teacher and taught share a relationship of same level.
10)  Emphasis is on self-learning.
11)  Professional improvement is specific to that skill or vocation being taught.


Informal Learning
Informal learning is never organised, has no set objective in terms of learning outcomes and is never intentional from the learner’s standpoint. Often it is referred to as learning by experience or just as experience. The idea is that the simple fact of existing constantly exposes the individual to learning situations, at work, at home or during leisure time for instance. This definition, with a few exceptions (see Werquin, 2007) also meets with a fair degree of consensus.

Characteristics of Informal Learning
Before you ever go to school or take part in a Mom-and-tot program, informal learning starts the day you are born and continues on until the day you die. Here are the characteristics of informal learning:

1. Informal learning is never organized.
There are no set formulas or guidelines. Examples of informal learning include activities such as teaching your child the alphabet, or how to brush his or her teeth. There is no prescriptive program of study for this.

2. Informal learners are often highly motivated to learn.
Unlike the formal learning environment of school, informal learners are often eager and attentive. A teenager showing a friend how to find an “Easter egg” in a video game is an example of informal learning. The gamer really wants to find out how to achieve his goal, so he embarks on a journey to figure out how. His friend becomes his teacher.

3. Informal learning is often spontaneous.
Learning happens anywhere, any time. The learner is inspired to learn because of an immediate desire to know how to do something or understand a topic. Or an informal “teacher” sees an opportunity to share their knowledge or wisdom with someone else. For example, we were recently standing in line at the airport waiting to go through security. There was a family in front of us. The father, who was holding the hand of his young son, who was about seven or eight, used the posters on the wall of the security area to teach the boy to read new words. The boy sounded out the words and they talked about the content of the poster. This not only helped to pass the time during a long wait, it was a great example of spontaneous informal learning.

4. There is no formal curriculum.
There is no program of study or prescriptive methods. Whatever methods used are the one that the person teaching knows how to teach… often based on their own experience.

5. The “teacher” is someone who cares – and who has more experience than the learner.
Even the word “teacher” here is a bit of a misnomer because professional teachers all have credentials, certificates or a teaching license. In the informal learning context, those leading the learning are likely to be emotionally close to the person who is learning, such as a mother, father, grandparent or other caregiver. An adult child teaching an older parent how to use new technology is an example.

6. The world is your classroom
It is a myth that learning happens in a school or in a classroom. With informal learning, there is no classroom. Your home, the neighbourhood park, the community and the world are the classroom.

7. Informal learning is difficult to quantify.
There are no exams and informal learning is difficult to quantify.

8. Often dismissed by academics and skeptics as being worthless.
Informal learning is often overlooked and not regarded as particularly valid learning. Some researchers and academics (though not all of us!) have the opinion that informal learning is less valuable than formal, prescriptive learning (due, in part, to the fact that it is difficult to quantify… and they believe that if it can not be quantified, it has no value).

9. Essential to a child’s early development.
Learning your mother tongue is an excellent example of informal learning. Imagine if a child were not exposed to any language for the first 5 years. How difficult would that child’s development become? It is an experiment that, as far as I know, has never been done. It would be considered too risky and unethical. Everything a young child learns at home is informal learning, from how to brush their teeth to how to say the alphabet to good manners. Without informal learning, we would never be able to cope in a formal learning environment.

10. Essential to an adult’s lifelong learning.
Informal learning is a lifelong process. It does not end when a child enters school and the formal system “takes over”. On the contrary, children continue to learn at home. As we get older, we learn from our friends. As we enter the workforce, we learn from our co-workers. Into retirement, we still learn from friends and also from those younger than us. An adult learning to read and write from a volunteer literacy tutor is one example. A retired office worker learning from her grandson how to use an iPad is another example.
Informal learning is what keeps us vibrant, mentally active and interested in the world around us, as well as our own development. Just because informal learning can not be quantified easily does not mean that it is not worthwhile – or even essential to our development and growth as human beings.
