We have developed, used and evaluated Spelling Bug, a computer program designed for teachers and students in primary school classrooms, in three schools in Brisbane over 1.5 years. We evaluated how learner-adaptive computer programs can be successfully integrated in primary classrooms in situ, using observations, interviews and computer-based data logs. The study found participating teachers felt time poor and they did not priorities learning to use new technologies. However, if they find add-on value they use the technology to complement traditional teaching. The response to using Spelling Bug was positive from both teachers and students. Students enjoyed a new task for working with spelling and they responded positively to the individual challenge the computer program set up for them. Teachers were pleased to find their students working independently and found time to support individual needs in the classroom. Retrieving information from a computer program gave support for teachers when making decisions on how to proceed with their teaching and presenting to parents.
