Models

Models are replicates of real objects and can be used in any teaching situation. They may be life size, smaller or lager than the things they represent. They are often called three dimensional visuals. When the real things are not available or too complex for the study models are used.

Models create a sense of realisation in a person. Models of new farm equipments, compost pits & sanitation devices & animals are mostly prepared for those people who are not in a position to see them in the actual form. They are used to create interest, promote understanding & influence the people to adopt a certain practice.

Models improve the efficiency of teaching because they have the capacity to bring into play all the five sense of human being. The following are such type of models: 1. Scale models, 2. Cross sectional models, 3. Working models, and 4. Simplified models.

Where an object is too large to be shown, a model of it can sometimes be used as a teaching aid. This applies particularly to buildings and other fixed infrastructure structures. For example, the construction of a fish/shrimp farms, nursery and culture ponds and the installation of equipments for ponds can be demonstrated by using a model, which can be taken to pieces in front of the audience.
