Zoraini Abas presented his experience with Mobile Learning at Open University Malaysia. You can view more details of what he presented here: http://eyeonlearning.blogspot.com/
Basically the University took some classes as a sample and had the professors/Tutors communicate via SMS with students upcoming assignments, test, and other course related information. At the end of the semester, the students were asked how their experience was and most were happy with receiving text messages of updates in the course. It provided them with an assignment.
My take: I think this was a really good example of how mobile devices can be used effectively in a learning organization. Students were given a sense of motivation and encouragement by the professor and allowed them to feel a sense of belonging within the course. Often, with distance education, it isn't easy for students to stay motivated and complete the required work, as most are working full time. And the technology used is very simple and not very new anymore, but the use was effective. In other instances, we have seen examples of social media being utilized for distance courses and face to face courses, as a supporting tool for students.
