This chapter explores classroom interaction in technology education, particularly interactions between students subsequently referred to as inter-student conversation. In authentic technological practice, working collaboratively in teams on the development of products or systems (technological outcome) is common practice, yet frequently in senior secondary schools, students work on individual projects, possibly with the help of a mentor. The summative assessment process is sometimes blamed for this; however, it is critical to encourage all our students to work collaboratively and cooperatively in technology. A vital part of working collaboratively is the ability to talk about and explore possibilities through conversation. This chapter explores the place and nature of conversation in learning technology and suggests the facilitation of inter-student intercognitive conversation as a powerful tool for advancing learning and collaborative practice in technology education.
