This correlational-predictive study investigated the relationship between teacher perceptions of technology use and observed classroom technology integration level using the "Technology Uses and Perceptions Survey" (TUPS) and the "Technology Integration Matrix-Observation" (TIM-O) instruments, developed by the Florida Center for Instructional Technology (FCIT) at USF. Anonymized data were obtained from FCIT that included 51 teachers from a Florida school district who completed the TUPS and were observed using the TIM-O. Linear regression was used to determine the overall relationship between perceptions and technology integration, as well as the overall predictive value of teacher perceptions on technology integration level. Both were found to be statistically significant; a low-moderate relationship existed between the TUPS and the TIM-O, and the TUPS was found to be a predictor of the TIM-O level. In addition, multiple regression was used to determine the relationship between each of the seven areas of the TUPS and the TIM-O level, as well as the predictive ability of each of the TUPS domains on the TIM-O level. Although none of the domains had a statistically significant relationship or predictive value, several subgroups had significant findings in the domains of confidence and comfort, and skills and usefulness. This study supports previous research in teacher perceptions and beliefs and furthers the research by including predictive relationships. Administrators, professional developers, and support staff can use these findings to target teacher professional learning opportunities in technology integration.
