Online learning is the new innovation used for education and MOOC plays the leading role in this area. Technology and students are inseparable in today’s world. In an online environment, students will be able to communicate and interact with others at their own pace and take time to consider comments and responses. Students tend to have more time to think and brainstorm ideas for certain topic discussions given by the teacher. Students also prefer technology as part of their learning as it is more handy for the students to access the information using technology wherever and whenever they want. Advantages of using ICT and technology in learning and teaching session were reported to be beneficial in attracting students’ attention, facilitating students’ learning process, helping to improve students’ vocabulary and also promoting meaningful learning to students. 
With the existence of technology and ICT and the rapid use of it in teaching and learning process, MOOC that stands for massive open online course is a web-based course available for free to any participant from all around the world  started to arise. MOOC provides free access to high-quality learning materials, offered by elite universities and they are conceptualised as online learning environments in which participants worldwide can create, research and share open educational resources .
Michael Gaebel’s brief history of MOOCs (Massive Open Online Course) Courses shows that MOOCs have been developing successfully since 2008, with the clear purpose of not only to provide and enhance more learning opportunities but also to improve students’ learning experience .
Mooc is one of the most recent innovations in education and has represent a current trend in online education . MOOCs offer students chances and opportunities to learn from the best educators at minimal cost. Since 2014, more than 400 universities around the world has started to be using MOOC and more than 73 universities have combined two styles of education : traditional class with advanced MOOC in addition to the teaching and learning session .
Massive Open Online Courses or widely known as MOOC has now gained its name all around the world among the top universities. MOOC has become one of the most current and recent innovations in today’s education. MOOC is the combination of online course, interactivity and mutual but virtual communication . MOOC basically allows students to evaluate, discuss and even interact with each other as MOOC is a mixture learning with the combination of teachers, students, videos, tests, communication and other related ICT tools. Universiti Kebangsaan Malaysia (UKM) is known for its massive routine of using MOOC as part of its teaching and learning process. The style of blended learning is practiced in UKM with the combination of traditional classroom along with the use of MOOC to further enhanced students’ development and understanding.
In relation to ESL learning, MOOC in some sense provides ESL learners the opportunity to ‘study abroad’ . Most leading universities in the world use MOOC as part of their teaching and learning process, including Malaysia, Universiti Kebangsaan Malaysia (UKM) also has its lecturers and staffs to conduct majority of their courses through online courses.
MOOC is said to be able to help students especially undergraduate students in their ESL learning without them realising it. In this situation, undergraduate students might have overlooked the importance of MOOC in their ESL learning and how MOOC indirectly helps them in their English language acquisition. As the growth use of MOOC is increasing rapidly in today’s world of education, there are quite a number of literatures related to the use and benefit of MOOC in teaching and learning all around the world.
However, there are no clear distinction on students’ acceptance on the use of MOOC for ESL learning provided by past researches and the lacking of literatures in the use of MOOC for language learning has lead the researcher to do a study on this phenomena of MOOC for ESL learning. The use of MOOC as part of the teaching and learning session is hoped to be able to help university students with their ESL learning.
2. The development of MOOC for ESL learning
Massive open online course or also known as MOOC is a web-based course available for free to any participant from any place in the world . MOOC is conceptualised as online learning environments in which participants all around the globe are able to share educational resources and at the same time interact with each other. MOOC is used in most of the elite universities around the world.  in her study mentioned that more than 73 universities use the combination of traditional classroom with advanced MOOC as their styles of education and the use of MOOC has increased from the year 2014 with more than 400 universities all around the world have acknowledged and started to use MOOC.  mentioned that the year of 2012 is ‘the year of MOOC’ According to The New York Times, MOOC is considered as convenient as MOOC learning style is quite flexible and learners can use various devices such as laptops or even perhaps using their own smartphones to have access to it, so learners, undergraduate students in this situation can have control of their own learning.
The Ministry of Education in Malaysia has developed three major plans for using ICT in education.  stated on their paper on the three measures planned by the Ministry of Education to implement the use of ICT in Malaysia’s education. One of the plans is to make use of ICT as a teaching and learning tool and relating MOOC to ESL learning, it is figured that ICT were able to encourage ESL learners’ independence and self-discovery skills especially in writing skills. The findings are in relation to this study as this study aims to investigate in what ways MOOC helps undergraduate students for their ESL learning.
In another previous study done by  which has developed an online language learning tools using MOOC considering learners would be motivated to participate and improve their knowledge, lead to a finding of 59% of the respondents were the learners of ESL learning. Their findings were aligned with the suggestion of MOOC does have impact towards ESL learners in their ESL learning as MOOC has been proven suitable to be used for language teaching and learning.  has discovered in their study that MOOC is to be said as the window for learners to train themselves with the sense of openness, self-efficacy and willingness to communicate. MOOC influences students’ openness in general and provides them with positive attitudes towards English language. Openness resulted to improving students’ ESL proficiency  and MOOC can be one of the mediums for students’ English language acquisition.
MOOC motivates students to interact with one another . A lesson in MOOC might need students to introduce themselves using perhaps a video or a paragraph of introduction in English language. Not to mention, there are rare occasions happening of the lesson of MOOC to being conducted in other languages other than English. Thus, with English language is to be considered as the dominant language in MOOC, the interactions and sharing knowledge with each other even with the tutor or teacher despite the language barrier might help students somehow to be more open to new knowledge and to be more willing to communicate and interact in English language. MOOC’s ability to supply a social platform for students to interact with one another among the participants managed to provide positive support for students to take charge of their own learning especially in ESL learning. The ability of students to work collaboratively in MOOC makes them to be able to set their own goals, developed new knowledge, improved their language skills and even built their self-confidence. The more frequent and autonomously students to be able to engage with the target language, it will give them more chances to acquire the language on their own .
3. Learning theories research on MOOC
There are quite a number of learning theories research related to MOOC based on previous studies. Literatures provided a variety of theories that different researchers used to further support their studies on MOOC. One of the theories used in this study is the sociocultural theory by Vygotsky (1978) which emphasises on the construction of cognitive schemes by individuals through interactions and communication. This theory is appraised to be one of the important theories relating to this study because social communications and social interactions help to build meaningful learning. In relations of MOOC for ESL learning, meaningful learning is needed for students to be able to acquire the language and develop their English language proficiency skills. MOOC is considered to be one of the mediums or platforms for students to build meaningful learning as virtual interactions and communications do happen in MOOC.
Potentially, participants of MOOC are able to work collaboratively in many activities provided in the MOOC prepared  despite the language barrier. It is argued that not all MOOC provide students with the activity of teamwork and collaboration that might help them in their ESL learning, however, regardless of that, through the content of meaningful learning provided by MOOC, students tend to learn from each other; in a sense of other students’ language, style of writing and even the use of vocabulary through the sharing of knowledge and information from the tasks given in MOOC.
On another note, MOOC is also related to the theory of connectivism by many scholars. The theory of connectivism is the learning theory that explains how technology created new chances and opportunities for people to learn. However, according to a study by , they mentioned on the relation of connectivism theory with MOOC is somehow argued by  on how they think that the theory did not provide enough explanation to learning phenomena because the theory is assumed to neglect other important aspects of learning. In relation to this study, this theory is not as significant as the other theory mentioned above as this study seeks to find out the relation of MOOC with language learning, not the impact of MOOC as the medium of learning alone
4. Undergraduate students’ acceptance and perception on MOOC for ESL learning
Students’ acceptance and perceptions towards MOOC may vary depending on their take on MOOC whether MOOC does help them in their ESL learning and in what ways can MOOC helps them improving their English language acquisition. In a related past research by , they figured out various factors that might contribute to different perceptions and acceptance among students when it comes to MOOC. Their study resulted to the indications of five learning competencies that might affect students’ participation in MOOC.
Among them are linguistic competence in English, self-efficacy and communication skills. Students with low proficiency of English language might have trouble to cope with MOOC as English language is to be considered as the dominant language in MOOC. There are possibilities that they might have issues in communicating and interacting with other participants in MOOC as they get intimidated with other people’s level of proficiency in English language. The idea of interacting in English language scares them but with practice and the actions are to be applied frequently eventually will help students to get familiar with English language. Obviously, students’ self-discipline plays a big role in determining the impact of MOOC  especially in relation to ESL learning.
In another study done by  which investigated the impact of integrating MOOC in an English language classroom, it is found through the findings that MOOC in a way helps students to enhance their writing and grammar skills. MOOC is claimed to be as an enjoyable learning and allows for grammar improvement for students through the tasks prepared.  also has the same opinion on that the most crucial way of learning English is to make students to get involved in the English environment.
 also mentioned in their study that MOOC can be expected to be useful in English language learning. This is parallel to the findings in a study done by  on her survey has resulted to the findings of how students are able to improve their grammar, writing skills and even vocabulary through collaborative learning and interactions.
Despite the lack of literatures of MOOC in relation to ESL learning specifically, based from the past literatures on MOOC, it can be concluded that even MOOC in general provides a solid platform for students to gain meaningful learning with content that in a way indirectly helps them to improve their English language learning even without them realising it and it is no longer questionable how MOOC has been proven to be able to provide all these catalysts for students to improve their ESL learning. It is proven that this study would be fruitful for all parties related to the ESL learning study.
