 Mastery learning, it is an instructional approach, it is a concept to just get mastery over any concept or information. It is basically teacher initiative or teacher's instruction or teacher's directed instruction towards students. And mastery learning basically teacher always make a plan how to teach his or her students. And this is basically fully you know including the teacher's directions and instructions. And teacher always plan that in how many days he or she will complete the lesson and how many quizzes or assignments will be included and when will be the midterm, when will be the final term. So all decisions are made through teachers. So they decide to get mastery over concepts or information and for mastery they always advise to read more books and to read more notes and to use multiple channels to get information and not only books to memorize but to get other information from different internet channels. So the burden is so much that it becomes a lecture that we have to work so hard. But its strengths are that when a concept is read with complete rich information and detail then they also remember it, relate it to it, validate it with different channels. So this is because their information is very rich. They know multiple backgrounds, multiple connections of information. They don't consult from one book or only from notes. They don't have superficial information but they have in-depth information. So mastery learning, the teacher directs the learning and sometimes only the sense of finding the solution or conclusion of the any concept that only the teacher introduces and then he says that the details are taken from the literature and the literature which is less than 10 articles you have to read and you have to discuss the idea of the research with the writer's point of view. So a lot of children come into the habit of book reading. After that they are aware of multiple sources. Some people are talking in favor of it, some are opposing it. In this way their divergent thinking increases a lot because by giving multiple angles to prove any information there is no increase in the information of a child. In fact it opens up the mind of a child that they should not explain the concept with one author. In fact multiple authors mean multiple school of thoughts. What have they explained? This can be a rich collection of information.
