Teachers today are expected to be able to apply a wide range of digital technologies in the classroom. Initial teacher education programs should prepare teachers to apply them with confidence. Pre-service teachers in Singapore responded to a survey on use of technologies in their personal lives and in their teaching, and how confident they were in using them. Among 17 applications, the most frequently used were those related to computer technology such as checking an online dictionary, web browsing and searching, emailing, and using computer software. Participants' use of computer software was frequent; however it was more so in their personal lives than in their teaching. The least used items included audio recording, video recording and global positioning system (GPS). Usage was found to be positively correlated with confidence, and while participants often had confidence in using the applications, their confidence was relatively low for items such as video and audio recording which they used the least. While teachers' use of computers is important, their ability and confidence to use other modern technologies for effective teaching should not be neglected. (Contains 4 tables and 1 figure.)
