Use of Mobile Phones in Language Learning: Developing Effective Instructional MaterialsMurat Saran Kursat Cagiltay Golge Seferoglu Cankaya University, Turkey METU, TurkeyMETU, AbstractGSM technology that is widely available in developing world countries. With its widespread use and its features andIn this study, we wanted to develop effective functions such as mobility, reachability, localization, instructional materials for mobile phones operated in and personalization, mobile phone technology offers a second generation GSM technology. In order to great potential in learning environments. With this achieve this aim, we have chosen English language consideration, our first and foremost aim in this study vocabulary learning as the subject matter. Since the has been to make use of this profound interest andmedium of instruction is English in a considerable potential, and contribute to the efforts to enhance number of universities in Turkey, many university existing educational practices, particularly in the students need to be proficient in the English language. developing regions of the world. Therefore, weHowever, these students state that they feel developed instructional materials to be delivered inadequate in expressing themselves in English and through mobile phones operated in second generation they report that they cannot use English after years of GSM technology in order to improve Englishinstruction.

This implies that learners have to know a certain size of vocabulary so that they can comprehend a text comfortably. On the other hand, the classroom activities are not enough to promote vocabulary learning for most of the students [4]. This means that additional practice must be provided in other ways.

According to Attewell, the amount of research explicitly exploring the use of mobile phones in education is still small, although there is an increasing amount of work-in-progress [6].
