Conceptual understanding is the understanding in which learners get the knowledge of the roots of the problem. Conceptual learning is easy to get if a learner has any prior experience in the related problem because experience (old ideas) helps them to get the concept (new ideas) in the best manner. In conceptual understanding, knowledge is constructed by the learners on the basis of their prior experiences.Learners are active participants in conceptual learning.In conceptual understanding, students learn the logic behind the problem.Conceptual learning should be done by performing many activities, research, and performances, related to the problem.Students tried to build a conceptual understanding through their thoughts, they covers all the possible aspects related to the problem to find out the logic behind it.Students are the knowledge makers, they make the knowledge by connecting the concepts from their previous knowledge and experiences.So that we conclude that Both (A) and (R) are true and (R) is the correct explanation of (A).?Additional InformationProgressive education which is given by John Dewey promotes the curriculum towards learning by doing, which helps the students to get the basic knowledge of the concepts because they learn by doing.children can get the roots of the concepts by engaging in the concepts to find the solution to the problem.Students cover multiple possible ways to learn the concept in progressive education.
