Teaching Methodology comprises the principles and methods adopted by teachers to enable student learning. The management strategies used for classroom instruction is called Teaching Methodology. Teaching Strategies are determined by the nature of learner. Effective Teaching Strategies are necessary for better student learning. Effective Teacher Learning and professional development is important for student achievement. Teaching Methodology is a process that promotes teachers' teaching skills. The best of Teaching Methodology is to control Student attention.The most basic teaching method is explanation. Explanation is characterized by its function as "a tool that is used by a speaker for understanding or 'giving a sense' to the object of communication, of a debate, or a discussion. The role of an explanation is to make clearer the meaning of an object (method, term, assignment) maintaining formally the necessary distance between the object of the action or study and the tools. In the learning/teaching process, explanation is a tool used by both, teacher and students. Its goal is to manifest comprehension.Traditionally, explanation belongs to such teaching methods where the information is transmitted from the teacher to the students (together with e.g. narrative, description or lecture). Skalková, 1999, says that in practice, individual forms of explanation often percolate. In this perspective, explanation is seen as the task fulfilled by the teacher with students passively receiving what is presented. Collecting feedback on students' perceptions of whether explanations are clearly identified whether students feel particular teaching assisted them in understanding the subject matter. Without student understanding, no explanation can be said to be clear We see explanation in a much broader sense.Communication in school is a mutual interchange of information among teachers and students, students and students during the educational process, i.e. students have an active role in the whole process (Mares & Křivohlavý, 1995). Using explanation in a mathematics classroom is a normal procedure, but its roles and forms vary. Predominantly explanation is seen as a tool for describing relevant phenomena, developing students' logical thinking, and guiding students by inductive judgement to generalizing. It leads to clarifying interrelations, demonstrating and justifying (Skalková, 1999, p. 172).Here, everything is discussed in a simple manner. So, this general discussion about different aspects of Teaching Methodology may help the people of the nation and the teachers of the world.
