Diagrams and tables are considered as the easiest ofteaching methods to convey the textual subjects to the mind ofstudents. They do not need for a great deal of explaining andgiving details. As far as I found the students always tend toreduce the amount of the study; I tried, skillfully, to do whatthey want without making any defect in the subject of study, soI found no way to achieve that by tables and diagrams.Because the personalities of the learners are variable; some ofthem depend on visual act, others resort to repetition of writing,and others rely on listening, therefore, and when we use themethod of diagrams and tables, we can involve vision sense inteaching in addition to hearing during listening to the lecture.Undoubtedly this method teaches the student how tosummarize the subject and concentrate on its basic pivots inaddition to contributing to watch the differences between thesepivots through examining the diagrams and tables.
