In this article the authors present a confirmatory factor analysis of the Teachers' Attitudes Toward Computers (TAC) and the Teachers' Attitudes Toward Information Technology (TAT) scales by Christensen and Knezek (1996, 1998) using large samples from three states. The TAC was reduced from 98 items and nine factors to 35 items and eight factors,…

This study examines the basic psychometric properties of the Swanson, Kotkin, Agler, M-Flynn, and Pelham Scale (SKAMP), a measure intended to assess functional impairment related to attention deficit hyperactivity disorder, in a sample of 1,205 elementary students. Reliability, factor structure, and convergent, discriminant and predictive validity…

The purpose of the study was to investigate the reliability and validity of a Turkish adaptation of Technology-Rich Outcomes-Focused Learning Environment Inventory (TROFLEI) which was developed by Aldridge, Dorman, and Fraser. A sample of 985 students from 16 high schools (Grades 9-12) participated in the study. Translation process followed…

Schools and districts should use a well-designed needs assessment to inform important decisions about a range of technology program areas.
