Development and Validation of Cell Phone Maintenance Training Modules for National Diploma Students.
ABSTRACT
The study was carried out to develop and validate cell phone maintenance training modules for national diploma students.
Five research questions were answered while five null hypotheses were formulated and tested at 0.05 level of significance. The study adopted research and development (R&D) design and was carried out in Lagos State, Nigeria.
The population for the study was 137 which comprised 35 Lecturers, 14 Instructors of Electrical/Electronic Technology from Department of Electrical/Electronics Technology,
Yaba College of Technology, Lagos State Polytechnic Ikorodu and Lagos City Polytechnic Ikeja, 21 Supervisors in MTN, GLOBACOM, Celtel, Etisalat and Samsung and 67 Road Side Cell Phone Technicians in Lagos State.
Purposive sampling technique was used to select 67 literate road side cell phone technicians from Ladipo Market Oshodi, Alaba International Market Ojo and Computer Village, Ikeja Lagos State.
The entire population of the lecturers, instructors and supervisors was involved in the study because of their manageable size. Cell phone maintenance training module questionnaire (CMTMQ) was used for data collection for the study.
The instrument was face validated by three experts. Internal consistency of CMTMQ was determined using Cronbach Alpha reliability method and the overall reliability coefficient of 0.86 was obtained. Seven trained research assistants were involved in the data collection using CMTMQ.

INTRODUCTION
Mobile communication technologies are modified computers with communication features. They have the capability of receiving, processing, transmitting data, voice and video signals through wireless link.
Darby (2005) stated that mobile communication technologies are those technologies which depend upon the broader phenomenon of internet protocol (IP) convergence when data, voice and video travel over a single channel.
According to the Report of United Nations Educational, Scientific, and Cultural Organization (UNESCO) (2005) IP includes devices such as internet, which converts the package that belongs to a voice, data or video exchange into the appropriate presentation.
Mobile devices can enable someone to use a variety of communications technologies such as: (i) wireless fidelity (Wi- Fi) – a type of wireless local area network technology;
(ii) Bluetooth – connects mobile devices wirelessly; (iii) global system of mobile (GSM) for communications and general pocket radio service (GPRS) data networking services for mobile phones;
(iv) dial-up services – data networking services using modems and telephone lines and (v) virtual private networks – secure access to a private network.
