Which among these is a dimensional teaching aid

Teaching aids prove effective only when they suit the teaching objectives and unique characteristics of the learners. They should have specific educational value being interesting and motivating.

 Key Points Models are used for demonstrating the three-dimensional representation of real things, or abstract things. They can be used in a wide range of instructional situations.

They have been particularly used for three specific purposes:

• As visual support material in instruction.
• As objects for study or manipulation in individualized learning.
• As a construction project for individuals, small groups, or even the entire class.

 Some of the advantages of using a model for classroom instruction are as follows:

• They can reduce very large objects to a size that can be conveniently observed and handled by you as well as the students.
• They can be used to demonstrate the interior structures of objects or systems with clarity that is often not possible with two-dimensional representations.
• They can be used to represent a highly complex situation or process in a simplified way that can easily be understood by learners.
• This can be done by concentrating only on essential features, eliminating all the complex and often confusing details that are so often present in the real-life system.

Thus, it is concluded that the model is a dimensional teaching aid.
