Learning may be defined as a relatively durable change in behavior due to experience. Thus, if the change in behavior is temporary, or due to instinct or maturation, it is not learning. The key feature of learning is experience. Any change in behavior in the absence of practice or experience does not qualify as learning.A teacher uses various methods and techniques to make the learning meaningful and purposeful and a concept map is one such method.Concepts maps: Concepts maps include graphical and diagrammatical representations to illustrate the meaningful acquisition of various sub-topics of a concept.It helps the learners to draw an outline of the topic/concept or briefly explain the concept or to link any two concepts of any subject by summarizing it.It shows the inter-relationships and cross-links among concepts under a subject matter which helps the learner in identifying the gaps in their knowledge.The arrangement of the concepts is from top to bottom, or be can say that general concept to complex.Concept mapping is a linkage of new concepts with previous knowledge.So we can conclude that a graphical tool for organizing, making linkages, and representing knowledge on a topic is called concept mapping.Hence option (3) is the correct answer.Additional Information Analogy: An analogy is saying something is like something else to make some sort of explanatory point.Example: You're as sweet as sugar.?Algorithm: Algorithms are a set of instructions for solving a problem.Example: Recipe of the baking cape.Verbalisation: Verbalisation is a process by which different psychological events in individual are made in verbal form.
