ICT use in the class processes of whole-class teaching was investigated. The investigation subjects were teachers who use ICT in their teaching on a routine basis. The results showed that: 1) ICT was used 3.3 times on average in 45-minute classes. The average required time for ICT use was 19.0 minutes. ICT was used for 83% of the first 5 minutes of the class, and for about 50% of the subsequent time. 2) The purposes of ICT use were the presentation of the study task in the introductory stage of the lessons, explanatory material during the development of the lessons, and repetition of the study matter at the last stage. 3) ICT equipment that the teachers commonly used were projectors, document cameras and computers. 4) No clear coincidence was observed between ICT equipment and the purposes of using ICT.
