This study was designed to examine the current trend and pattern of teachers' concerns about technology integration. Eighty-six in-service teachers in a graduate course participated in the study at a midwestern state university during the summer semester of 2002. The Stages of Concerns (SoC) Questionnaire was used to assess teachers' seven stages of concern: awareness, informational, personal, management, consequence, collaboration and refocusing. This study found that: (1) teachers' concerns as a whole were very intense in these stages informational, personal and refocusing; (2) there were significant statistical differences in teachers' concerns in most stages of concern among teachers with three levels of perception of their implementation status; (3) the concern profile for each of the three subgroups supported the hypothesis of Hall, George & Rutherford (1977) regarding the development of stages of concern for the three different user groups: inexperienced, experienced and renewing. International implications for teacher technology integration are proposed.
