The term usability is defined as by The International Organisation for Standardisation (ISO) ISO 9241-11 [16] as ‘the extent to which a product can be used by specified users to achieve specified goals with effectiveness, efficiency and satisfaction in a specified context of use.’
According to Nielsen [17], usability means the measure of the quality the users’ experience when interacting interface....usability is not a surface gloss which applied at the last minutes or before the releases of the system or product; but it is deeply affected by every stage of the analysis, design, and development [18].
Usable systems are easy to learn (learnability), efficient to use (efficiency), easy to remember (memorability), not error-prone (errors), and satisfactory in use (subjective satisfaction) [17].
The ultimate goal of usability is meeting the needs of to users’ satisfaction [17]
...advantages of usability encompass increased productivity, enhanced quality of work, improved user satisfaction, and reductions in support and training costs [19]. The reduction in costs has attracted many project managers and interface designers to employ the theory of usability when designing the interfaces as reported in [20, 21].

Pedagogical usability is often focusing on the aspects whether the interface, tools, content, and the tasks of the e-learning environments support learning in various contexts according to certain pedagogical objectives (Silius et al. 2003, Tervakari et al. 2002).

Research in pedagogical usability has been active recently. For example Kukulska-Hulme et al. (2004) conducted a project during 2001-2003 in Open University (UK). During the project it was recognised that "to get to the heart of pedagogical usability, we have to understand more about the impact of requirements in relation to communities, contexts and disciplines." The research group found therefore several layers of usability: contextspecific, academic, general and technical. In detail:
• Context specific usability relates to the requirements of particular disciplines and courses.
• Academic usability deals with educational issues, such as pedagogical strategy.
• General usability issues are common to most websites and include aspects such as clear navigation and accessibility for users with special needs.
• Technical usability addresses issues such as broken links and server reliability.

One distinct feature of mobile learning over e-Learning is mobility [6].
Hence, researchers and scholars are becoming enthusiastically in coining the term ‘mobile learning or m-learning’, such as ‘mobile learning as the point at which mobile computing and e-Learning intersect to produce an anytime, anywhere learning experience [7].
According to Nyiri [8], m-learning is fundamentally e-Learning delivered through mobile computational devices such as Palms, Personal Digital Assistants (PDA), Pocket PCs, smart phone, digital cell phones, and any other handheld devices. The use of mobile devices with the wireless network technology flourishes mobile learners to get convenience, expediency and immediacy of mobile learning in appropriate time and accessing the appropriate learning contents [7].
Additionally, mobile learning is the next generation of e-Learning and important instrument for lifelong learning [49].

MOBILE LEARNING FRAMEWORK.

Mobile learning is not learning through mobiles phones or learning over a wireless connection even though the capabilities of running multimedia features has increased in recent years. But mobile learning is the evolution of elearning, which completes the missing component of an e-learning solution. Mobile learning most suits for those mobile parties in education institutes. So, utilizing mobile devices in education is mainly considered as enhanced tools.
