EDGAR DALES CONE OF EXPERIENCE Edgar Dale- known as the father of modern media in education Advocated the use of audio-visual aids in teaching Introduced cone model in His book Audio- Visual Methods in Teaching(1957) Cone model is used to explain the hierarchy of experience through teaching aids

Edgar Dale deals with 3 main sources of experiences

Direct sensory contact which involves doing. Teaching aids or visual aids which involves observing. Oral and printed materials which involves symbolizing.

Involvement of more knowledge senses and work senses in teaching learning situation may provide true experiences. The knowledge is provided through true experience or core experience. The multi senses help in multi sensory perception. The learning through multi senses is more stable and true learning.BASIC ASSUMPTIONS OF CONE MODELMAIN COMPONENTS OF CONE MODELType of teaching aids: Still pictures and movies Projected and non- projected aidsInvolvement of senses: Knowledge sense and Work sensesTeaching effectiveness in the form of hierarchyForm of learning experiences: Core experience and intensive experience.EDGAR DALES CONE MODEL

Direct Purposeful Experience:-

Experience gained through direct contact with the help of senses.An ounce of experience is better than a tonne of theory.Best possible method to teach effectively.

Contrived Experience:-Imitation of reality.Simplification of real object either in size or in complexity.

Dramatic Participation:Representation of real events.Eg. Puppet show, tableau, pageant, role play etcDemonstration:Performance of certain complicated processes by the teacher.Field Trips:Experience involving observation.Exhibits and Museums:Brings outside world into the classroom.Television:Brings a dimension beyond the range of motion pictures.Brings real events as it actually happens.Motion Pictures:An abstract version of real events.Radio, Recordings and /still pictures:Provides one way communication and auditory experience.Visual Symbols:Promote a keener interest and a better understanding of concepts. Eg. Maps, charts, graphs , diagram etc.

Verbal Symbols

The word idea or concept expressed here has no resemblance to the objects for which they stand.Spoken word is primary and written word is secondary.

INTERPRETATION OF DALES CONE OF EXPERIENCECone classifies sensory aids in terms of greater or less concreteness and abstractness of learning experiences.

Lower levels of cone encourage active learning.

Higher levels of cone provide data faster but need more instructional support.

As we travel up to the cone abstractness increases.

As we go down the cone concreteness increases.

ADVANTAGES OF EDGAR DALES MODELThe various types of teaching aids are included and explained in relation to the learning experiences.

Teaching aids are analyzed by involvement of senses which are the gateway of learning.

The multisensory perceptions leads learners to true experience and true knowledge.

Teaching aids are useful for realizing the cognitive and psychomotor objectives of learning.

The use of teaching aids increase the teaching and the learning effectiveness.
