The current study aims to develop a valid and reliable instrument that measures secondary school teachers' attitudes towards ICT use in teaching and learning process. A cross-sectional survey design was employed with a group of 173 teachers. Based on the literature review, a pool of 21 items was proposed and reviewed by a board of experts. As to psychometric quality of the scale, the Cronbach's Alpha coefficient, item total variance and item distinctiveness indices were estimated. The results illustrated that Teachers' ICT Attitudes Scale (TICTAS) has a high level reliability standard (? = .898) and also Exploratory and Confirmatory Factor Analyses indicated good goodness of fit estimates. As a result, a reliable and valid scale comprising of 16 items loaded in two factors (ICT willingness and ICT anxiety) was developed. [For full proceedings, see ED571332.]
