6 Benefits and Problems of Out-of-class Language Learning Most of the authors agree about the concept that learner autonomy is a functional concept that should be attempted in order to be instated into the learning process. Dafei (2007) does not identify autonomy only like an ability to obtain the other skills; she indicates it as an aim of the learning process and it is one of the most important case which determines if a learner reaches his or her potential or falls short of that potential. Cotterall (2000) denotes this issue in the similar way, emphasizing the fact that autonomy is not just a goal for the highly committed learners of the language but for all of the learners. Little (2002) declares two main reasons about why autonomy learning is worthy of its position as a well known theme; firstly, the students will be engaged and motivated with their learning and accordingly more likely to be impressive, since it would be more personal, also secondly, if the students are proactively committed to the learning process, the difficulty of motivation finally can be solved, due to autonomous learners have advanced the reflective and attitudinal resources to control temporary motivational issues (in Dafei, 2007). In the same way, Littlewood (1999) states that autonomy learning is an indisputable goal for the learners from all the places, since it is noticeable that none of the learners will. The advantages of learner autonomy contain six positive and good sides. Firstly, the learners of the language are directly involved in their process of learning. The processes are comprehension and knowledge instruction, subjects ,materials, rapidity and the progress of development, plus the learning process itself. Knowledge construction is the outcome of discourse between teachers and students also it is formed on their requirements. moreover the learners can choose the Topics, materials, and level of difficulty and complexity. Speed and process of development of learner autonomy can be corresponded to the learners. Learning process is favourable to be more successful and satisfied.
