After the professional development program, the teachers’ technology usage for preparation of education and instruction were increased, both in-classroom (sub-dimension -4)-and out-classroom (sub-dimension -1) settings. This result is parallel with the studies revealing that the in-service training programs increase the teachers’ technology usage for preparation of education and instruction both in-classroom and out-classroom environments (Russell et al., 2007; Van Braak et al., 2004). The teachers who were attended to the assessed PD program, inclined to motivate their students for using information technologies in a greater degree (sub- dimension -2). Brinkerhoff (2006) stated that, the teachers who attended to the PD programs encouraged their students for technology usage. The increase of technology usage in ITP participant teachers was also transferred to the their students, according to consideration of teachers; the students technology usage were increased (sub- dimension 3). This result is parallel to the Brinkerhoff (2006).
