Principles to Enhance Online InteractionWhen many people think about computers, tablets, smartphones and other Informational Technology (IT) devices, they picture individuals alone seemingly fixed to the screens and keyboards of their devices. Similarly, when people think of students using those devices for learning, they imagine the students alone, perhaps at desks or tables in their homes, far from their classmates. However, such images of individualised involvement with electronic learning tools often fail to look below the surface. In reality, students are often using their devices to interact with others, and frequently those others are their fellow students.The purpose of this paper is to share ideas for facilitating and enhancing those student-student online interactions. These ideas flow from a learning technology known variously as cooperative learning (Johnson & Johnson, 2013) or collaborative learning (Bruffee, 1993). In this paper, the neutral abbreviation 'CL' will be used. The paper begins with background information on CL, including supporting learning theories and research, as well as a definition. The main section of the paper explains eight CL principles, including what each principle means, why it is important and how it can be applied in IT environments.
