Although we have used the word “communication” a lot in daily life, we still don’t quite fully understand “communication” as a conception as well as a practice. Nevertheless, we know one thing for sure, it is unimaginable to picture without communication how human being would survive and what our civilizations would become. The communication process happens in every second everywhere on the planet, and it takes place across various visible/invisible boundaries. We never stop our pursuit in improving communication to meet our need and desire for a change and a better world. Media is a great invention in connecting and reshaping us as well as our communication process. Our reliance on media, both the traditional and digital forms, has never been stronger than today. Focusing on media and communication, this course consists of both theoretical introduction and discussions on specific cases of communication phenomena in the mediated space. The theoretical introduction will touch on the emergence and establishment of communication as a field of academic inquiry. It will comb the origin and development of a range of theories and schools in communication studies. It encourages students to question the relevance of these theories to our contemporary digital society. The following part will lead students to engage with the discussion on how media technology speeds up the process of and expands the scale of communication, and the subsequent consequences. One focus will be concrete cases of the visual-aural communication in the digital age, investigating the interactions between these activities and the era we live in.
