This study investigated the properties of an online course and it aims to examine how the ICT environment develops academic writing ability in a course on sociolinguistics – the study of the relationship between language and society and society and language with regard to topics such as second language acquisition, mother tongue, linguistic diversity, dialects, diglossia, language and identity, linguistic policy, and linguistic-educational policy. The preliminary research findings demonstrate that the online course accords actual added value to learning and contributes to the sum total of the quality of self-learning and its compatibility with the spirit of today's demands. The online course enriches the ways of learning and empowers the study experience.
