This study investigated Australian preservice teachers' use of computers during teaching practice. Participants were 46 graduates entering a preservice elementary teacher education course at an Australian university in 1999. Data were collected using the Personal Computer Efficacy Questionnaire at the beginning of the course. The School Computer Access Survey (which also solicited information on demographics and types of computer equipment and programs used) was administered twice during the year following a practice teaching in schools. Data analysis indicated that respondents had a high level of belief in their ability to perform basic computing tasks. The results also highlighted the lack of technology use within Australian elementary schools and found that classroom teachers who did not use computers themselves did not encourage student teachers to use them as part of the teaching-learning process. Though computer use by student teachers rose over time, there was still a low level of computer use overall, with one in four student teachers not using computers in the classroom.
