Which one of the following statements is not true about 'concept maps'?

The correct option is Concept maps should be constructed by teachers only.

Understanding Concept Maps:
A concept map is a visual diagram that illustrates relationships between concepts, ideas, or information. It consists of nodes (representing concepts) connected by labeled arrows or lines (representing relationships).

Let us analyze each statement to determine which one is not true:

1. Concept maps represent a collection of interconnected concepts and links connecting them: This statement is true. Concept maps visually show how different concepts are interconnected through clear linking phrases.

2. Concept maps are hierarchical in nature: This statement is true. Generally, broader and more general concepts are placed at the top, with more specific concepts arranged below them.

3. Concept maps help in linking prior knowledge to new instruction: This statement is true. Concept mapping allows learners to connect new concepts to existing knowledge structures (schema), promoting meaningful learning.

4. Concept maps should be constructed by teachers only: This statement is not true. Students should actively construct concept maps themselves to organize their thoughts, deepen comprehension, and enhance active learning. Restricting concept map creation to teachers only defeats its primary pedagogical purpose as a student-centered learning tool.

Hence, the statement that is not true is that concept maps should be constructed by teachers only.
