Class Size Reducation Achieving the quality and quantity demands in an educational system together remains a challenge. Over the past decade, governments had been giving increased attention to build the largest number of schools across nationwide. That is because it had a moral duty to granting equal opportunities in education for its citizens. Now, this political trend has changed little in the past few years. Governments are seeking not only to ensure the social Justice in education, but also they aime to raise the quality of education as a result of economic competitiveness at the global. level. To this end, they have a plan to limit class sizes to a maximum of 15 students. One of advantages of this potential procedure is assisting teachers to distribute their efforts on students equally. So, the academic achievement of students and their ability to absorption of information can be increased. In addition to this, by focusing on every student as individual in classroom, teachers can exploit individual differences between their students to discover talented students and to encourage brainstorming which stimulates creative thinking in class. Moreover, with limited number of students, it will be more easier for teachers to make a control on classroom and school adminstration can accurately observe any abnormal behavior. As a consequence of that, a lot of violent events in schools such as bullying can be disappear. Some opponents argue that it could threat the social justice by excluding some students from going to school, especially if governments are incapable of building more schools to achieve this goal. However, people should also have equal opportunity in the quality of education which only will be attained by this plan. Needless to say, governments must find more creative methods to learn students beyond physical buildings such as electronic learning and outdoor classrooms.
