History of Edgardale
Edgardale (27 April 1900 – 8 March 1985) was an American science student. The famous developer of experience cones He has done many works. For audio and video teaching Including methods for analyzing animation content He is a professor of education at Ohio State University. Edgar Dell believes that concrete experiences Will make learning different from abstract experiences. Therefore, teaching media is based on experience In order from 10 easy to difficult experiences, called the Cone of Experience, as in the picture.
The steps of the learning experience and the use of each type of media are as follows:
Step 1: Direct Purposeful Experience is the most tangible experience. Allowing students to learn from real experiences such as playing sports, cooking food, growing vegetables or raising animals etc.
Step 2. Contrived Simulation Experience is the case where the experience or the real thing has limitations. It is necessary to simulate various things. Those to study instead, such as models of specimens, astronomy simulations, etc.
Step 3: Dramatized Experience is an experience that is held instead of direct experiences or real events that occurred in the past or may be thought, dreams can be studied with experience. Direct or simulated experience, such as acting, role play, etc.
Step 4: Demonstration is an explanation of facts, sequences, ideas, or processes that are suitable for the content that needs understanding, expertise, or skills such as the demonstration of the play, the demonstration of the teacher of physical education, etc.
Step 5: Field Trip is a learning experience obtained from knowledge sources outside the classroom in real conditions. To give the opportunity Students know many aspects, such as studying knowledge from important places such as ancient sites, industrial plants, etc.
Step 6: Exhibition is an experience for students to see by most, may display things such as real objects, models, demonstration materials, charts, movies, etc.
Step 7: Motion Picture / Television is an experience that provides both animation and sound effects. But television is tangible More than movies Because television can bring the events that are happening At that moment, came to see at the same time called “Live Event” while the movie is Logging of events And have to go through the film washing and editing process before being shown for viewing
Step 8: Still images / sound recordings (Picture / Recording) is an experience that can be perceived in some way between listening and speaking. Which is more abstract, such as a phonograph tape, which requires amplification, and stills, including both translucent images used with overhead projectors Slides, still images from computers and audio recording images Used for opaque projector etc.
Step 9: Visual Symbols (Visual Symbols) are symbols that can be perceived by the sensory system of the eye. There is more abstract It is necessary to consider the learners’ experience as the foundation, such as charts, advertisements, cartoons, maps, and various symbols.
Step 10: Verbal Symbol is a language symbol. Is the final experience Which is the most abstract, such as using words instead of words, such as words, descriptions, books, brochures, brochures that use letters, numbers instead of meaning, which are considered the most abstract experiences.
