Mobile learning or m-learning, a relatively new concept, has attracted the interest of educators, researchers, and companies developing learning systems and instructional materials. This study investigated the use of integrating use of mobile technologies, data services, and multimedia messaging systems to increase students' use of mobile technologies and to develop environmental awareness. Data was collected using "usefulness of mobile learning systems" questionnaire from a sample consisting of 20 male and 21 female undergraduates enrolled in computer education and instructional technologies classes at the Near East University in North Cyprus. Students voluntarily participated in a six-week program using mobile telephones to transmit photographs of local environmental blights and to exchange pictures and observations. Participants learned ways to maintain clean environments and increased their awareness of environmental concerns. Responses on questionnaire differed significantly based upon gender and grade.
