Processes and Inputs for Applying Media Resources. Using instructional Media.
The instructional devices prepared by the teacher take the centre stage in this teaching methodology. The teaching aids are used to provide a concrete experience about the lesson for the children since they are seen or heard or both. Modern classrooms which are equipped with audio-visual equipment and a rich collection of audio-visual materials for learning enable the teacher to plan ideal teaching-learning scenarios. Today the teaching of some special topics in science are facilitated through tape recordings, radio programs and television lessons.
Such audio-visual tools which range from the simplest tricks, stones, and chalkboards to the more recent micro-films and video tapes are now referred to as instructional media. The science teacher must be knowledgeable in planning and using these non-human resources for effective classroom instruction.
The audio-visual materials widely used in teaching science can be grouped into the following types:
5. Graphic materials, e.g., political maps and relief maps
6. Mounted pictures, photographs and clippings
7. Diagrams, drawing, painting and sketches
8. Aquarium, terrarium, mini weather station, mini zoo
9. Collection, e.g., variation in plants and animals
10. Clippings, e.g., inventions, significant science events.
11. Tapes and records for audio lessons
Some audio-visual equipment that help greatly in teaching science which are usually found in the schools audio-visual centre or media centre are.
A general listing of educational media for teaching and learning science includes the following:
The science resource centre may provide a space where the children can construct or improvise tools which they will need in various laboratory activities. The work area should provide simple construction tools, drawing materials and boards for preparing unit displays. A fully equipped media centre provides equipment for viewing films and audio devices for listening.
As a teaching technique, the use of instructional media provides a concrete and direct learning experience for children depending on their age group. Still in the concrete stage of their intellectual development they understand and attach meanings to objects and phenomena which they personally see, hear, manipulate, and witness.
The use of films, slides and flat picture afford the children the opportunity to view objects or organisms at close range such as films on microorganisms and internal organ systems.
They are able to view distant places which might be difficult for them to reach, like a safari which shows the habitat of wild animals. Projected materials communicate directly thus eliminating much use of words.
Instructional media can greatly enrich teaching if used effectively. Some suggestions for their effective use are here given.
Local radio programs may include broadcasts about current science information. Science lessons are also presently shown on television. Films can be rented or borrowed from the Film Exchange Centre or the National Media Production Centre. Such as resource. Such resources if available in the locality will undoubtedly help achieve some specific objectives of a science lesson. Science teachers should not miss the chance of utilizing them to great advantage.
2. Involve the children in a variety of learning activities that would require construction of audio-visual materials such as preparing posters, bulletin board displays, exhibits, puppets, models, etc. these activities will encourage pupils to design their own learning tools as well as enhance their creativity and resourcefulness. They may be motivated to take photographs for their own record of significant scientific events.
3. If possible, provide a workshop which is equipped with simple construction tools, drawing materials, recording equipment, radio and television set.
4. Choose carefully the films, educational programs and printed materials to be used to suit the children’s age, needs, interests and level of understanding.
5. Models and miniatures must be checked as to accuracy of the information being presented. Use materials that are similar to the original if possible. Scaled models are highly informative.
6. Avail of information regarding radio broadcasts that can supplement special science lessons. These broadcasts usually provide up-to-date information and can disseminate such to a great number of listeners in very short time. But like films, they must be selected to the suit the age level and background of the children.
Sample lessons using instructional media.The science teacher should be able to identify which lessons can be taught more effectively with the use of instructional media and what media may be used. A few are mentioned below:
