This study investigated teacher educators', prospective teachers', and K-12 teachers' opinions about the effectiveness of ICT related courses and the ways to improve the courses in Turkey's pre-service teacher education programs. The researchers used both quantitative and qualitative research approaches within the data collection and analysis processes. The data were collected from 111 teacher educators, 1,330 prospective teachers, and 1,429 K-12 teachers through questionnaires; and from 6 teacher educators, 6 prospective teachers, and 6 K-12 teachers through interviews. Even though a majority of the participants felt that ICT related courses are effective, most participants recommended that these courses need to be redesigned to be more beneficial in practice.
