Teaching aids assist students in learning. These aids consist of video, audio and hands-on tools to help involve the students and enhance the learning experience.
Teachers begin using visual, audio and hands-on aids as early as preschool. Teaching aids can be as basic as a blackboard or whiteboard. Audio and visual equipment, such as DVD players and video projectors, are commonly used as tools for learning with a very effective output.
Students tend to get more involved when learning if teaching aids are implemented into the curriculum. Hands-on aids, such as computers, maps and other tools that require some sort of interaction from the students, have the highest levels of effectiveness.
The tools are designed to involve the students, promote interaction, and promote faster learning and better comprehension. Being able to see, hear or get involved in a topic creates a much better method for learning.
How a teacher chooses to use learning aids in a classroom can vary dramatically. The main factor in the effective use of teaching aids is that a skilled teacher is behind the tools being used.Learn more in Conditions & Diseases
