Introduction to Extension EducationMeans for dissemination of education and

informationHelps to change human behaviour through use of

knowledge, skill and attitudeWas first implemented in Britain in 1894

Main aim: to reach out to the rural and farming population for promoting social and cultural development.

Definition: It is an applied science consisting of content derived from research accumulated field experiences and relevant experiences drawn from behavioural sciences and combined with useful technology into a philosophy, principles and methods focused on the problems of out of school education for adults and youth.2 Home Science Facilitator Jasmina Sangani

Introduction to Extension Education

Purpose: To bring about a change in attitudes and practices of the people with whom work is done.

Results: Narrows the gap between what is and what is required or desired.

It encompasses the educational, economic, cultural, social and communal objective of learning and teaching.

Principles of Extension Education that need to be catered to

Principle of Voluntary EducationPrinciple of Self- HelpPrinciple of SatisfactionPrinciple of Self- DependencePrinciple of Motivation and EncouragementPrinciple of Cooperation and ParticipationPrinciple of Local LeadershipPrinciple of whole family participationPrinciple of slow and a continuous processIn agreement with the National Policies and

ProgrammesUndertaken by Trained Subject matter specialistsBe based on applied technology and science, and

in accordance with appropriate teaching method5 Home Science Facilitator Jasmina Sangani

Communication

Essential for the functioning of any programmeIt is a two way process by which the messages are

transmitted from the source to the receiver.It is the process by which information, decisions

and directions pass through a social system and the ways in which knowledge, opinions and attitudes are formed or modified

It is a process by which two or more people exchange ideas, facts, feelings or impressions in a way that each gains common understanding of a message bringing the sender and receiver together.

Gestures and symbols are very important in the process of communication6 Home Science Facilitator Jasmina Sangani

Page 7: Extension Education 1 Home Science Facilitator Jasmina Sangani

Visual AidsEnsure more effective communication.Attracts the receiver through the sense organsUseful in achieving the objectives by creating

interest, motivation, desire and activity.Classification of audio visual is based on the sense

organs involved:Audio- radio, tape recorder, telephone, public

address system, songs, slogans etc.Visual- These are of two types:

Non- projected- posters, charts, pictures, models, flash cards, cartoons, black- board, bulleti- boards, handbills, paper, clippings, exhibitions

Projected- Slides, film strips, silent films, overhead projections, opaque projections, slide projections, close circuit TV, films, television, VCR, drama, puppetry and songs and dance programmes

Types of CommunicationOne-way Communication (Didactic

Method)The flow of communication is one way from the communicator to the audience.

e.g. lecture method in class roomsDrawbacks

knowledge is imposedlearning is authoritativeless audience participationno feedbackdoe not influence human behaviour8 Home Science Facilitator Jasmina Sangani

Page 9: Extension Education 1 Home Science Facilitator Jasmina Sangani

Types of CommunicationTwo- way communication (Socratic

Method)Both the communicator and the audience take part

The audience may raise questions, and add their own information, ideas and opinions to the subject.

Learning process is active and democratic

More likely to influence behaviour than one- way communication

9 Home Science Facilitator Jasmina Sangani

Page 10: Extension Education 1 Home Science Facilitator Jasmina Sangani

Types of CommunicationVerbal Communication

The traditional way of communication has been by word of mouth.

The advent of written and printed matter are of comparatively recent origin.

Direct verbal communication by word of mouth may be loaded with hidden meanings

It is persuasive.Non- direct or written communication may not be as persuasive as the spoken word

10 Home Science Facilitator Jasmina Sangani

Page 11: Extension Education 1 Home Science Facilitator Jasmina Sangani

Types of CommunicationNon- verbal Communication

Communication without wordsIt includes a whole range of bodily movements, postures, gestures, facial expressions etc.

Silence is non-verbal communication

It speaks louder than words

11 Home Science Facilitator Jasmina Sangani

Page 12: Extension Education 1 Home Science Facilitator Jasmina Sangani

Types of Communication Communication

Formal Communication

Informal Communication

- follows lines of authority - grape- vine

communication- exists in all organizations- could be more active if the formal channels do not cater to the information needs

12 Home Science Facilitator Jasmina Sangani

Page 13: Extension Education 1 Home Science Facilitator Jasmina Sangani

Types of CommunicationPersuasion (influence)

art of winning friends and influencing peopledoes not employ force or deliberate manipulationDefinition: A conscious attempt by one individual

to change or influence the general beliefs, understanding, values and behaviour of another individual or group of individuals in some desired way

Persuasive communication is more effective than coercion or authoritative communication

It can change lifestyle and modify the risk factors of diseases

When persuasive communication is deliberately employed to manipulate feelings, attitudes and beliefs, it becomes 'propaganda' or 'brain washing' 13 Home Science Facilitator Jasmina Sangani

Page 14: Extension Education 1 Home Science Facilitator Jasmina Sangani

Types of CommunicationInformation

The primary function of health communication is to provide scientific knowledge or information to people about health problems and how to maintain and promote health.

Information should be easily available to the people . Exposure to the right kind of health information can eliminate social and psychological barriers of

ignorance, prejudice and misconceptions people may have about health matters

Increase awareness of the people to the point that they are able to perceive their health needs

influence people to the extent that unfelt needs become felt needs, and felt needs become demands

14 Home Science Facilitator Jasmina Sangani

Page 15: Extension Education 1 Home Science Facilitator Jasmina Sangani

Types of CommunicationMessage

It is the information which the communicator transmits to his audience to receive, understand, accept and act upon.

It may be in the form of words, pictures or signs.

Health communication may fail if the message is not adequate

Kinds of CommunicationKind Descriptions Examples

Speaking- Listening The sender speaks and the receiver listens

1. Listening to a lecture or discourse2. Listening to a talk or a lesson on a radio- set.3. Listening to a tape or disc

Visualizing- Observing The sender uses visual symbols and the receiver observes

1. Use of an illustration or diagram

Speaking- Listening, Visualizing- Observing

The sender combines speaking and visual symbols while the receiver listens and observes simultaneously

1. An educational television programme2. A video lesson3. An educational movie

Writing- reading Kind The sender uses written words and symbols. While the receiver reads or feels those

Media Systems

The total communication effort is based on three media systems:

Interpersonal communication

Mass media

Traditional or folk media 24Home Science Facilitator Jasmina Sangani

Page 25: Extension Education 1 Home Science Facilitator Jasmina Sangani

Interpersonal CommunicationIt is the most common channel.It is also called face-to-face communication

It is more persuasive and effective than any other form of communication

It is important in influencing the decisions of the undecided persons

The superiority of interpersonal communication over mass media for creation of motivational effect has been well documented.25 Home Science Facilitator Jasmina Sangani

Page 26: Extension Education 1 Home Science Facilitator Jasmina Sangani

Mass MediaChannels of mass media: TV, radio,

printed media.It has the advantage of reaching a

relatively larger population in a shorter time as compared to other means of communication.

It is a one-way channel of communicationIt carries messages from the centre to the

peripheriFeedback systems are poorly organizedThey are usually not effective in changing

established modes of behaviour.26 Home Science Facilitator Jasmina Sangani

Page 27: Extension Education 1 Home Science Facilitator Jasmina Sangani

Folk MediaNetwork of traditional or folk media

includes folk dances, singing, dramas, Nautanki in Uttar Pradesh, Burrakatha in Andhra Pradesh and Harikatha in Western India besides informal group gatherings, caste or religious meetings.

These are important channels of communication close to the cultural values of the rural population.

They have been the principal instruments of preserving the cultural heritage.

Health messages may be communicated through these traditional media.

27 Home Science Facilitator Jasmina Sangani

Page 28: Extension Education 1 Home Science Facilitator Jasmina Sangani

FeedbackIt is the flow of information from the audience to

the sender.It is the reaction of the audience to the message.If the message is not clear or otherwise not

acceptable the audience may reject it outrightThe feedback thus provides an opportunity to the

sender to modify the message and render it acceptable.

In interpersonal communication the feedback is immediate.

In mass communication it takes sometime to get feedback

Feedback is generally obtained through opinion polls, attitude surveys and interviews.

It can rectify transmission errors.28 Home Science Facilitator Jasmina Sangani

Page 29: Extension Education 1 Home Science Facilitator Jasmina Sangani

Use of Audio- Visual AidsSuggestions for an effective and efficient use

of audio- visual aids:The school must have the audio-visual

department for acquiring, co-ordinating and providing counseling about the use of audio-visual aids.

The advisory services of the departments in national institutes connected with the audio-visual aids should be sought.

The liaison should be maintained with the state level and national institutes connected for getting the audio- visual materials on loan for special use in the schools.

29 Home Science Facilitator Jasmina Sangani

Page 30: Extension Education 1 Home Science Facilitator Jasmina Sangani

Use of Audio- Visual AidsSuggestions for an effective and

efficient use of audio- visual aids:Teachers must update their

knowledge about teaching aids through professional associations and journals

Prepare your own improvised teaching aids and catalogue for use.

The training sessions should be held for effective use of audio- visual aids

30 Home Science Facilitator Jasmina Sangani

Page 31: Extension Education 1 Home Science Facilitator Jasmina Sangani

Use of Audio- Visual AidsSteps for developing and organizing an audio-

visual program for teachers: Integrate audio- visual aids with the curricular and

co-curricular activities of the schoolCorrelate the audio- visual aids with the prescribed

textual material.Get the audio- visual lessons evaluated frequently to

improve the performance of a teacherTrain the teachers for proper use and care of audio-

visual equipmentSet up an audio- visual resource center for

cataloguing the teaching- aid materialsPrepare lesson- wise instructional guides for use

with the audio- visual aids.

31 Home Science Facilitator Jasmina Sangani

Page 32: Extension Education 1 Home Science Facilitator Jasmina Sangani

Use of Audio- Visual AidsCriteria for Selection of Audio- Visual AidsSubject Relatedness- The audio- visual aids should

be closely related to the lesson topics. These aids should give the feeling of entertainment and amusement.

Supplementary Role- The audio- visual aids must be used to supplement the classroom teaching. The audio- visual aids should be selected in such a way that they assist the classroom instructor

Accuracy- It should be observed that the audio- visual aids should have accurate details as any incorrect information conveyed by these aids can cause a lot of harm.

32 Home Science Facilitator Jasmina Sangani

Page 33: Extension Education 1 Home Science Facilitator Jasmina Sangani

Use of Audio- Visual AidsCriteria for Selection of Audio- Visual Aids

Accessibility- The audio- visual aids to be used for a given lesson should be easily accessible and available to a teacher.

Variety- A large number of audio- visual aids should be used for teaching a lesson because use of a single aid produces monotony

Cost Effectiveness- The audio- visual equipment should be used frequently and for a large number of students so that it becomes cost- effective.

33 Home Science Facilitator Jasmina Sangani

Page 34: Extension Education 1 Home Science Facilitator Jasmina Sangani

Use of Audio- Visual AidsCriteria for Selection of Audio- Visual AidsPre- viewing- For selecting audio-

visual aids for classroom situation , they must be pre viewed and appraised.

Utility- Only those audio- visuals should be selected which are useful and help further education.

Flash CardsSmall cards of generally 25cm x 30 cm size

which are shown for a few moments before the class to send across a message or impart an idea.

The idea on the flash card should be brief.These cards are usually used for the drill in

various subjects.They may also be used for reviewing a

lesson with the students.Flash cards can be used with other graphic

aids to make the lesson effective.35 Home Science Facilitator Jasmina Sangani

Page 36: Extension Education 1 Home Science Facilitator Jasmina Sangani

Preparation of Flash CardsCut a foolscap chart paper and cut it

into four equal parts.Write the content on it either in the free

hand or using lettering stencils and sketch pen.

The height of the writing on the flash cards should be approximately 5 cm so that the whole class can see the flash cards clearly

36 Home Science Facilitator Jasmina Sangani

Page 37: Extension Education 1 Home Science Facilitator Jasmina Sangani

Advantages of Flash CardsCan be used to introduce and present topicsCan be used to apply information already gained by

students to new situationsCan be used to review a topicCan be used for drill and practice in elementary

classesCan be used to develop the cognitive abilities of

recognition and recall of studentsA series of special purpose flash cards can be used

for playing educational games to couple learning with fun

Can be used as a supplementary aid and can be effectively used with other materials

37 Home Science Facilitator Jasmina Sangani

Page 38: Extension Education 1 Home Science Facilitator Jasmina Sangani

Bulletin BoardsThe material on the bulletin board should

change periodically as new lesson topics are taught.

The students can be asked to collect the display material to be put on the bulletin board.

During the course of the lesson, the teacher can make special reference to the displayed material to make his lesson lively.

38 Home Science Facilitator Jasmina Sangani

Page 39: Extension Education 1 Home Science Facilitator Jasmina Sangani

Using the Bulletin Boards EffectivelyProcure enough illustrative material from

various sources on a given subject or topic.Sort out the relevant material specific to the

subject or topicDisplay the material on the bulletin board in an

aesthetic manner keeping the color balance and harmony in view.

On the top centre of the bulletin board fix a title for the specific subject of the display material

Below the title fix a brief description about the specific subject or topic

39 Home Science Facilitator Jasmina Sangani

Page 40: Extension Education 1 Home Science Facilitator Jasmina Sangani

Using the Bulletin Boards Effectively

While teaching make reference to the material displayed on the bulletin board.

Keep the interest of the students alive by involving them in collection of material for the bulletin board

The height of the bulletin board should be one metre above the ground.

The area where the bulletin boards are fixed should be well-lit.

Puppetry- Different types of a Puppet

Type Description

String puppetsOr marionettes

Marionettes consist of puppets with hinged body parts which are controlled by nine strings running through screw eyes in the hands of a performer. Pulling of these strings produces required movements in the puppet. These puppets are mainly manipulated by professional puppeteers

Stick puppets These are painted cardboard cut-outs attached by sticks. The actions of these puppets are manipulated by the teacher and students by hiding behind a screen so that only puppets are visible to the audience

Shadow puppets These are silhouettes (dark shape of someone) of cardboard which produce shadows on a white screen. The motion of these silhouettes is manipulated by the teacher and the students

Finger or hand puppets

Hand puppets are round balls painted as heads with overflowing colorful costumes. These are worn on fingers which operate their movements from below the stage

Types of Radio ProgrammesKind of Programme

Description

Talk A talk is the sequential narration about a topic by a single speaker. A good radio talk is characterized by naturaleness of voice; pleasant tone punctuated by humorous incidents, human interest stories and word pictures

Discussion In a discussion a group of participants air their views in the from of panels, interviews and debates. A number of voices make a discussion interesting but much depends on the moderator who sets the tone of the discussion. The end of discussion is followed by a summary to review the major inputs which emerge out of the discussion or debate

Dramatization These radio lessons have various interesting sound effects to amplify emotions and give the mental pictures of the characters in a pot. Lessons on stories or dance dramas would make use of special sound effects.67 Home Science Facilitator Jasmina Sangani

Page 68: Extension Education 1 Home Science Facilitator Jasmina Sangani

The teaching procedure of a radio lesson

Procure and study in advance the nature and content of the radio lesson

Prepare students for the radio lesson by informing them about the background of the lesson

Allow the students to listen to the radio lesson and you as a teacher note down the important points covered by it.

Make use of the noted down points to discuss the radio lesson with the students

Clarify and amplify the main points of the radio lesson using other visual aids68 Home Science Facilitator Jasmina Sangani

Page 69: Extension Education 1 Home Science Facilitator Jasmina Sangani

Micro-ProjectorThese are slide projectors designed to project the micro-film slides or microscopic slides to a group of students simultaneously.It reduces the cost of instruction as it eliminates

the expensive individual microscopies for each student.

Enlargement on the screen is quite large for the students to see and get more details

Accompanied with the teacher's commentary, micro- projection can assure the instructor that the students are understanding what is being taught to them which is otherwise not possible with viewing slides individually through microscopes

69 Home Science Facilitator Jasmina Sangani

Page 70: Extension Education 1 Home Science Facilitator Jasmina Sangani

Overhead ProjectionIt is a vital teaching aid.It has made projections so simple and

easy that it has replaced chalk- board completely in many classrooms.

It produces images on a screen behind and over the head of the teacher

It can be used in soft light conditions and enables the students to take down notes while viewing the projections on the screen

70 Home Science Facilitator Jasmina Sangani

Page 71: Extension Education 1 Home Science Facilitator Jasmina Sangani

Advantages of Motion Picture as Teaching AidIt captures attention, arouses interest and imparts

emotional experiences. It can bring far-away experiences, events and actions

filmed earlier to the classroom and motion part of the film heightens reality

By slow motion filming and projection, the stages in a process, acting or event can be viewed in details

Many slow processes can be shown as fast by filming them at the right stages of development to educate students quickly

It allows events which are out of reach or specific to be seen without getting near those events

It can enlarge or reduce things and show the internal parts, processes and working of things
