Between laptops and mobile phone, mobile phones are still their early stages for teaching and learning environments. PDAs are frequently used with mobile wireless services, such as Short Message Service which is SMS according to Mauve, Scheele, & Geyer (2001) and Multimedia Message Service. Some of institutions of higher education have joined mobile wireless phones into their teaching and learning environments in order to improve their educations quality.According to Crescente and Lee (2011) The definition of M-Learning or Mobile Learning, has many different meanings for different communities, that refer to another tools which is educational technology, E-Learning and distance education that is focuses on learning across environments and learning with only using mobile devices.
Besides that, mobile learning has various different meanings and is has many different names such as U-Learning, M-Learning, personalized learning, learning while mobile, anytime and anywhere learning, and handheld learning. One definition of mobile learning is, “any sort of learning that happens when the learner is not at a fixed, predetermined location, or learning that happens when the learner takes benefit of the learning chances offered by mobile technologies”. So, with the use of mobile devices, learners can learn anywhere and at any time.
Mobile learning is considered to be the ability to use mobile devices to assist teaching and learning. According to Singh (2010). Mobile learning is surely not merely the conjunction of ‘mobile and learning ‘which it has always indirectly meant mobile E-Learning.
Besides that, its history and development have to be understood as both between a continuation of conventional E-Learning and a reaction to this conventional E-Learning and to its perceived insufficiencies and limitations. It is the mobile feature of mobile learning that makes it stand apart from other types of learning, learning experiences and specifically designing that exploit the chances that mobility can offer us. Furthermore, M-Learning also focuses on the flexibility of the learner, and learning that reflects a focus on how society and its institutions can accommodate and support an increasingly mobile population and interacting with portable technologies. This is because mobile devices have features and for supporting learners. For example, podcasts of lectures can be made obtainable for downloading.
Moreover, learners are to expect to engage with these learning resources at the same time as away from the traditional learning spaces. Over the past ten years mobile learning has grown from a minor research interest to a set of significant projects in schools, workplaces, museums, cities and rural areas around the world. The M-Learning community is still fragmented, with different national perspectives, differences between academia and industry, and between the school, higher education and lifelong learning sectors
