INTRODUCTION Programmed instruction is a method of presenting new subject matters to students in a graded sequence of controlled steps. Programmed Instruction was developed by B. F. Skinner. Students work through the programmed material by themselves at their own speed and after each step test their comprehension by answering an examination question or filling in a diagram. They are then immediately shown the correct answer or given additional information. Computers and other types of teaching machines are often used to present the material, although books may also be used.

It’s main focus is to bring desirable change in the cognitive domain of the learner’s behaviour. The structure of teaching method is that the selected content is analyzedand broken into smaller elements.Each element is independent and complete in itself .The programmer develops frames based on each element. Responses are also provider to the learner in some different leaflets. The correct response of the learner is the new knowledge. Immediate confirmation of correct response provides reinforcement to the learner and proceeds to the next frame. Wrong responses requried feedbacks.

COMPONENTS

The components of programmed instruction are:

Behavioural objectives, clearly stated Small frames of instruction, carefully sequenced Self-pacing instructional sections, units,modules Active learner response to questions Immediate feedback and positive reinforcement

Steps in programmed instruction design

Specify the goals of instruction:what is to be learned. Identify the entry skills of the learners,i.e.what is the current level of skills of the

learners. Develop a series of steps that will get the students form where they are to where

they should be. Instruction is programmed in small steps , i.e.successive approximations to the

desired behaviour. Provide appropriate reinforcement.

Types of Programmed Instruction:1. Linear programming

2. Branched programming

Linear programming

The founder of this programming is B.F.Skinner. It is based on theory of operant conditioning. It tells that” A certain direction can be given to human behaviour”, for this purpose activities is needed to divide in small parts and make their analysis.

        Linear programming is based on five fundamental principles-

1.     Principles of small step.

2.     Principle of Active responding.

3.     Principle of immediate confirmation.

4.     Principle of self pacing.

5.     Principle of student testing.

The assumption behind the linear programming is that student learns better if content is presented in small units, student response if immediately confirmed, results in better learning, student’s error create hindrance in learning. Student learns better in Laissez fairy environment.

Frame size in small steps; include only one element of topic at a time. Each step is complete in itself. It can be taught independently and can be measured independently. Frame structure is based on stimulus-response-reinforcement. There are four types of frames. Introductory frames, Teaching frame, practice frames and testing frames.

Responses in linear programming are structured responses and are controlled by programmer and not by learners. Immediate confirmation of correct responses provide reinforcement, wrong responses are ignored.

It is used for secondary level students, used for achieving lower objectives of learning especially for recall and recognition, useful for student of average and below average intelligence can be used in distance education programme.

Limitations of Linear programming-

1.      No freedom for student to response.

2.      Based on learning theories which were formulated by experience conducted on animals. A human being is more intelligent, than animals, he has got an intelligent brain.

3.      Every learner has to follow the same path; therefore, student may cheat from one another.

4.      Wrong responses are avoided in the programme. No remedy is provided for them.

Branched programming

The founder of Branched programming is Norman A Crowder. It is based on configuration theory of learning. It is a problem solving approach. It is stimulus centered approach of learning. It is based on three basic principles.

1. Principle of Exposition

2. Principle of Diagnosis

3. Principle of remediation.

Assumptions behind this programming are-

A.    Student learns better if he is exposed to whole situation or content.

B.     Student errors help in diagnosis.

C.     Student learns better if remediation is provided side by side.

D.    Student learns better in democratic environment.

Frame size is large. There may be a Para or page in the frame. Frame structure is Exposition- Diagnosis- Remediation types. There are two types of frames- Home page (for teaching and diagnosis) & Wrong pages (for remediation). Responses not rigidly structured and responses are selected by learner and not by the programmer. Confirmation of correct responses provides reinforcement. Wrong responses also help in diagnosis of weaknesses of the learner. Remedy is provided on the basis of diagnosed weaknesses of the learner. Error helps in diagnosis of the weaknesses of learner. More than 20% error rate can be accepted. The purpose of Branched programming is to draw out weak points of learner and provide remedy for recovering those weaknesses.

Branched programming is used for secondary as well as higher classes. Higher objectives can be achieved such as multiple discrimination etc. It is useful for students of above average and high intelligence. It can also be used in Distance education programmes.

Limitations of Branched programming

1.      It does not consider learning process whether learning is taking place or not. Main emphasis is on diagnosing the weakness of learners and providing remedy to them.

2.      There is no sequencing of pages. Student finds it difficult to follow the steps. He does not find it exciting or motivating, therefore he does not want to go through these pages.

3.      More emphasis on remediation rather than teaching. Hence, it is only a tutorial approach.

Computer Assisted Instruction (CAI)

A self-learning technique, usually offline/online, involving interaction of the student with programmed instructional materials.Computer-assisted instruction (CAI) is an interactive instructional technique whereby a computer is used to present the

instructional material and monitor the learning that takes place.CAI uses a combination of text, graphics, sound and video in enhancing the learning process. The computer has many purposes in the classroom, and it can be utilized to help a student in all areas of the curriculum.CAI refers to the use of the computer as a tool to facilitate and improve instruction. CAI programs use tutorials, drill and practice, simulation, and problem solving approaches to present topics, and they test the student's understanding.

Typical CAI provides:

1. Text or multimedia content2. Multiple-choice questions3. Problems4. Immediate feedback5. Notes on incorrect responses6. Summarizes students' performance7. Exercises for practice8. Worksheets and tests.

Types of Computer Assisted Instruction:

1. Drill-and-practice :Drill and practice provide opportunities or students to repeatedly practice the skills that have previously been presented and that further practice is necessary for mastery.2. Tutorial Tutorial activity includes both the presentation of information and its extension into different forms of work, including drill and practice, games and simulation.3. Games Game software often creates a contest to achieve the highest score and either beat others or beat the computer.4. Simulation Simulation software can provide an approximation of reality that does not require the expense of real life or its risks.5. Discovery Discovery approach provides a large database of information specific to a course or content area and challenges the learner to analyze, compare, infer and evaluate based on their explorations of the data.6. Problem Solving This approach helps children develop specific problem solving skills and strategies

Advantages of CAI

• one-to-one interaction• great motivator• freedom to experiment with different options• instantaneous response/immediate feedback to the answers elicited• Self pacing - allow students to proceed at their own pace• Helps teacher can devote more time to individual students• Privacy helps the shy and slow learner to learns• Individual attention• learn more and more rapidly• multimedia helps to understand difficult concepts through multi sensory approach• self directed learning – students can decide when, where, and what to learn.

Limitations of CAI

• may feel overwhelmed by the information and resources available• over use of multimedia may divert the attention from the content• learning becomes too mechanical• non availability of good CAI packages• lack of infrastructure

Computer Managed Instruction

The term computer managed instruction CMI simply stands for the instruction managed with the help of computer technology. In CMI

the computer gathers, stores, and manages information to guide students through individualised learning experience. It directly calls for the services and applications of computers and applications of computers in the field of instruction.The information on a student’s progress in working with the computerised program, namely his performance on every test item, keeping track of his mistakes and strengths and providing a valuable feedback to the teacher etc. can all be managed effectively by the computer. Such a system which maintains this kind of book keeping along with the instructional programme is called as CMI.CAI is more effective only when it is linked to CAI. It helps to assess the learners present level of knowledge, weaknesses or gaps in his learning and remedial action possible.

Four areas of computer management support to teachers are,a.       Constructing, scoring, and analysing tests.b.      Keeping records of student performance and progress through courses.c.       Providing guidance to students and advising them on the choice of next course module.d.      Reporting on the performance and progress of students to individual students, tutors and educational administrators of the institutions.

In CMI, on the basis of initial interaction with the student, the computer suggests the type of models of instruction for him. The computer will note down the attainment as well as draw backs of the learner in order to construct his profile. This profile is used to plan the learning unit for the student, whether it should be modified, enriched or a remedial module should be added. Student’s achievement is measured in relation to criterion attainment with reference to the syllabus of the module and assessed in relation to the course requirement. Following the computers decision, there could be discussion with the student and teacher and the instruction of the student is so managed that efficient personalised learning takes place. As said in the above definition, computers are able to perform the task of managing instructions with the help of a category of suitable software programme specifically designed for this purpose. CMI analyses the relationship between various factors pertaining to a pupil and suggests activities appropriate to individual students. Some of the functions performed with the help of such developed soft wares related to the organization and management of instructions are described below.

1. Diagnosis of entry behaviour of learners

Computer programmes help in the early diagnosis of the strengths and weakness of the learners in terms of their previous knowledge and experiences related to a

10

particular knowledge and skill area, their interests, attitudes and aptitudes, the needs and motives as well as other personality traits for determining their potentiality for going

ahead in the learning of a particular instructional course or achieving a set of instructional objectives.

2. Setting of instructional objectives

Computer soft wares are available that can help in analysing test data and other data base information about the characteristics of the learners in relation to the needs and purpose served by a particular type of instruction at one or the other stages of school, college or public education. It will help in formulating the goals and objectives for a particular coarse or piece of instruction.

3. Generating individualized instructional plans

Depending upon the need, characteristics, nature, and individuality of the learners, computer software are able to generate and organize individualized instructional plans for countless learners at one or the other times-average, gifted, slow, disabled.

4. Generating instructional materials and learning experiences                                    

Suiting to the individualized instructional plans and strategies computer software can generate appropriate instructional material and opportunities of interactive learning experiences to the learners of varying need, interests, and abilities. A huge data bank of all types of information and instructional material is easily available through well prepared software packages, websites, online conferencing, networking etc. The material generated and developed for instructional purposes may be used on a computer based system or in other forms of instructions. eg. Programmed instruction.

5.Availability of instructional material into curricular units

For the proper organization and management of the instructions, an inventory of the instructional resources available to the learners may be stored in the computer’s data bank. The total resources may be divided into properly required units having clearly specified set of objectives. There shall be clear directions available for telling the learner s what to do for achieving the stipulated objectives. It may asks them to read a book, work-off self-administered paper and pencil exercises , conduct experiment with a science kit, attend group instruction or see a film , and so on.

6.Monitoring of progressThe computer managed instruction proves very effective in monitoring the progress of each and every individual learner.

CONCLUSION

While not popular, programmed instruction continues to be used today. Recently the application of programed instruction principles was reapplied to training in computer programs, after some popularity in a series of books on functional programming and combined with Benjamin Blooms taxonomy to teach college students. These programmed instruction gives immediate feedback to the answer elicited and can learn more and more rapidly.
