Discourse analysis of teaching computing online

This paper analyses the teaching and learning of computing in a Web-conferencing environment. A discourse analysis of three introductory programming learning episodes is presented to demonstrate issues and effects that arise when teaching computing using such an approach. The subject of discussion, the interactive nature of discussion and any actions performed by both the teacher and students were coded in order to determine how the approach to teaching impacted upon discourse. Student participation increased under student-centred approaches as the responsibility for the direction of curriculum-based discussion was devolved from the teacher to the students. However, teacher-led approaches incurred less of a collaborative overhead relating to coordinating activity between people and operating the technology. The data analysed and the approach adopted represent a subset of outputs from a PhD thesis investigating the teaching and learning of computer programming using Web-conferencing.
