This study, using content analysis technique, examined the types of job-related problems that the Turkish computer teachers experienced and the types of social support provided by reciprocal discussions in an online forum. Results indicated that role conflict, inadequate teacher induction policies, lack of required technological infrastructure and technical support, and the status of computer subject in school curriculum were the most frequently mentioned problems. In addition, 87.9% of the messages were identified as providing emotional support, while 3.1% messages were identified as providing instrumental support. It is concluded that content analysis technique provides an invaluable tool to understand the nature of communication and social interaction patterns among users in online environments. CMC in education should not only be considered to be a tool for content delivery and instructional interaction, but also a feedback mechanism and a platform for professional support, as well as an informal learning environment.
