Out of 32 articles, we reviewed twenty -one of them that mostly explained the challenges of large classes. The articles were published between (1970 -2010) years. Results: Dealing with large classes constitutes a real challenge to every teacher: The major hypothesis is that effective teaching and producing learning is critically constrained by the large size of classes and the students' perception about large classes being negative. The findings indicated that small -group learning are more effective in promoting greater academic achievement, and enhances favorable attitudes toward learning. Conclusion: Most researches showed that benefit usually occur when class size is reduced to less than 20 students otherwise problem of acquisition and classroom management arise and learning process will be not occur effectively. There are other variables such as the quality of teachers, students' degree of motivation, and role of the parents may interface and come into play in leaning process.
