This article examines adult online education by investigating the complex relationship between technology and community. The aim was to explore online teaching in relation to the handbook dilemma teachers meet in their teacher profession by focusing on participation and sharing opportunities. This study analysed several handbooks that aim to help teachers design and implement online education. The advice in the handbooks was contrasted against two empirical cases. Specifically, the study examined how two cases – online adult education courses and special (...) needs teacher training courses – implemented online education with respect to participation and sharing. The analysis suggests that pedagogy is the crucial point and a planned pedagogy is absolutely necessary for designing and implementing effective online education, education that encourages participation and sharing. The findings showed that some handbooks offer meaningful guidance regarding the development of online education, but other publications were not helpful which creates a dilemma for teachers. (shrink)
