With the rapid development of new technologies, many changes in activities, content distribution, strategies, and attitudes in the field of on line education have brought on. In this context, the spectacular development of Internet and wireless technologies and the proliferation on more and more handheld devices such a mobile phones, smartphones and personal digital assistant's (PDA's), provides motivation for studying their impact on a natural area of education like e-learning and ``Mobile learning'' abbreviated as m-learning which indicates an ensemble of educational solutions which allow learning on mobile instruments through wireless transmission. Furthermore, handheld devices are also brought into the classroom as an alternative learning platform for educators and students. Thus, e-learning techniques oriented towards m-learning are obviously a new frontier for education becoming more widespread each year because of it can be valuable when used as a part of a well-planned and properly supported education and training environment.

The educational research community has proposed authoring tools for taking test in handheld devices. Initially, authors introduced e-dap as an e-learning author tool implemented using only software under open source agreement in order to cover completely educational experience using ubiquitous computing for managing, distributing and capturing educational content. Using the same platform at the server side, different clients versions were progressively developed so that different mobile devices could be integrated to the system, including PC’s as well as Smartphones and PDA’s equipped with Windows Mobile Operating System. Also, some authors have been proposed authoring tools for taking tests in handheld devices like PDA’s and WAP-based phones but all of them suffer the same drawback: On line Internet connection is required in order to take a test any.

In this paper, we introduce a new application, running at the client-side of the previously proposed architecture, that using Java Mobile technology and the XML markup language allows us to measure the level of each student’s progress checking their test marks statistics, using a low cost and widespread device as a standard mobile phone compatible with Java Mobile technology. Application runs off-line and only is Internet connected (GPRS, UMTS or HSDPA) whenever should be required: in order to download new versions of tests and to upload the student tests results to the main server. We compare performance between different client versions of e-dap: standard PC, PDA and the new version introduced in this paper, running on a basic mobile phone compatible with Java Mobile Technology and request user feed-back through informal interviews and a questionnaire. As a result a summarize evaluation of usability, user performance and behavior was discussed respectively.
