The Common Agenda of European Council (2001) defines six levels of proficiency in a language. All level that explained includes following skills: reading and listening comprehension as receptive or input skills, writing and speaking as productive or output skills. There are three fields, which should be considered when describing mobile assisted language learning: (1) physical or touchable, (2) pedagogical, and (3) psychosocial areas (Bachore, 2015). Physical issues in this research related to a size of the screen, storage capacity, battery life and the speed of processor of the mobile phone. The issues of Pedagogical in this research refer to confirming the tasks suited to the affordances of the mobile phone used. Psychosocial issues in this research refer to the social environment. While laptops and desktop used for work or research purposes, it also can be the substitutes devices for the mobile devices. Mobile devices designed for personal or social purposes.
Based on Jarvis & Archileos (2013) if learner uses a computer in their process of language learning. Every procedure which includes this process that makes the learners improve their language skills counted as a Computer Assisted Language Learning (CALL). CALL has become founded and recognized in the language education in the early 1980s. The early domain of CALL limited only to PC or desktop computers with a few basics programs of mechanical software. However, this area has developed over the years to include virtual learning environments, mobile applications, online blogs and vlogs (video blogs), online courses, etc. The improvement and mobile technologies advance, their widespread availability has directed to the new creation area called Mobile Assisted Language Learning (MALL). Chen (2013) explain that this term used both in the informal and the formal area of foreign languages learning. The term of MALL actually is different with CALL as of its personal or private use, the function of portable technology devices like mobile phone allows the learner to learn in the new ways. MALL is a quite new research area, although people nowadays have been using personal mobile or portable devices (Gafni R. , 2009). Gafni et.al (2017 ) stated that the main gap in MALL to the traditional language learning process is the mobility and connectivity of the learner, besides to the potentials of spatial and time shifts yielding improved learning opportunities.
