AbstractTechnology has completely changed the way of living and learning. It has almost become difficult to live without it. It has brought revolution in every field including teaching and learning process. Educators often focus on the use of technology to impart better teaching and to improve the skills of the learners. They try to infuse the skills with the help of technological devices, especially smartphone, a high-end mobile phone that offers more advanced computing ability and connectivity than a contemporary feature phone, and WhatsApp, a messenger app for smartphones that uses the internet to send messages, images, audio, and video, which have become part and parcel in one’s life. The aim of the present paper is to focus on the use of mobile, especially smartphone, to teach the English language skills. It briefly discusses the latest trend Mobile Assisted Language Learning (MALL) that became more popular in the recent past. It further provides some of the mobile applications which are highly helpful in improving one’s own English language skills. The core of the paper is to show how WhatsApp, a social networking application, can be a boon for the modern teacher to enrich the four basic skills of his/her learners through various activities.Keywords: Smartphone, WhatsApp, MALL, Language Skills, Pedagogical agentInformation and Communications Technology has a great impact on the methodology of teaching English language over the past decade. Educators have focused increasingly on the use of technology to impart better teaching and to improve the skills of the learners. Teachers are exploring novel ways to disseminate and engage students in the learning process. In the beginning the teachers sought the assistance of audio-visual aids to create interest among the learners. With the advent of computer, particularly Internet, teachers took the aid of World Wide Web to develop the skills and creativity among the learners. Yedla remarks thus:The main aim of the technology is advancing and enhancing the classroom teaching especially to enhance group teaching to self-learning. The experience of independent learning may encourage the students to continue the learning process on their own in English language communication skills for their future purpose.1 Now, mobile devices, especially smartphones, are replacing laptops. The teachers no more depend on a computer at home or the computer lab. One of the main reasons for this is that, of all the technological devices, smartphone is closest to every learner and a supplement of internet connectivity. Today, neither teachers nor students come out without smartphones in their hands. It has almost become a part and parcel of their lives. The learners may not know how to work on a computer, but they know well how to operate a mobile. This is another reason why smartphones are attracting teachers to use them as pedagogical agents to inculcate skills among the learners. In fact, most language teachers agree to the advantages of using smartphones in teaching inside and outside the classroom for learning. They feel that a smartphone is the most powerful communication medium even richer than Internet as it can be accessed without any technical limitations. It is due to this, the heads of the educational bodies are encouraging the teachers and the learners to carry mobiles to the institutions with a view to better learning. Hence, the trend Mobile Assisted Language Learning (MALL), “a teaching and learning methodology that uses mobile phones or other handheld devices with some form of wireless connectivity, such as phones, PDAs and tablets.”2 It can be considered an ideal solution to language learners barriers in terms of time and place. Its applications can facilitate learners in interacting with others collaboratively anytime and anywhere. Thus, the development of MALL as a new approach for education has implications on the way students and teachers in educational institutions interact.Mobile Assisted Language Learning is the most recent learning strategy that is used in the classroom. It is defined as “learning across multiple contexts, through social and contact interactions, using personal electronic devices.”3 A form of e-learning distance education, m-learners can use mobile device educational technology in many locations at their time of convenience. M-learning technologies include handheld computers, mp3 players, notebooks, mobile phones and tablets. It focuses on the mobility of the learners, interacting with portable technologies. Using mobile tools for creating learning aids and materials becomes an important part of informal learning. It is a significant tool that supports and integrates effectively in enhancing the language skills. It is more useful for doing activities outside the classroom. Such activities enable learning to be more directly connected with the real world experiments. Moreover, learning through mobile phones outside the classroom has the advantage of better exploiting learner's free time; even the students on the move can improve their learning skills. Sharples, Arnedillo-Sanchez, et al state that MALL assists in “linking people in real world and virtual worlds, creating learning communities between people on the move, providing expertise on demand, and supporting a lifetime of learning.”4Mobile technique for language learning is effective and easy as the mobile device is quite a popular gadget. Language learning through games generate interest and make the process simple. Mobile learning techniques involve the principle of ‘anytime anywhere’, which makes it available to the user as and when required. Mobile phones effectively utilize time and the user is not bound by time constraints. A mobile language class supports a variety of learning styles in a timely and interactive fashion. It is a paradigm shift from e-learning to m-learning. So, the influence of technology on current academics is such that in near future the whole context of learning will come under single umbrella of m-learning, especially with the help of smartphones.Smartphone permits learners to access the desired learning materials. Wi-Fi technology in mobile devices allows learners to access supplementary learning materials from the Internet. Teachers can use smartphone to communicate and send learning materials to their learners anytime. However, the main challenge is to provide students with the skills and knowledge to be informed and engaged online learners. Important in that process is presenting persuasive illustrations of learning connected to students’ lives (present and future) and to bring those experiences into the classroom. The most effective way to do that may be through the smartphone learners own. The opportunity is “to leverage those digital devices and online experiences to enable and encourage in our students’ life-long learning, learner autonomy, and critical digital literacy.”5Smartphone is more convenient as it is accessible from virtually anywhere. It is more interesting and easy way of learning the language. As everybody maintains a mobile, one may install the dictionaries and look up the meaning of a word immediately when they want to know the meaning. Apart from finding the meaning, one may also learn how to pronounce a particular word by listening to the audio available in that application. If one owns a smart phone, there are some useful mobile applications for language learning. To improve vocabulary one may download Manhattan Review Vocabulary Builder, and do the exercises available in the application and improve his/her vocabulary. One may also find idioms on various categories and learn those idioms. ‘Toontastic’ and ‘Puppet Pals’ are some apps that enable younger learners to create stories using animated characters and recorded speech. Besides the above statements, there are umpteen apps which can be downloaded to improve one’s own language. One such app that is immensely helpful in improving one’s English grammar is ‘English Grammar Test.’ The app provides thirty tests for the Intermediate and the Upper Intermediate students. One of the best features of this app is that after answering a bit in each exercise, it provides the rule in simple terminology. The following are some of the screenshots of the ‘English Grammar Test’ App:
