The purpose of the study was to examine effects of a compact training for developing web sites on teachers' web attitude, as composed of: web self efficacy, perceived web enjoyment, perceived web usefulness and behavioral intention to use the web. To measure the related constructs, the Web Attitude Scale was adapted into Turkish and tested with a sample of 156 teachers. Then, a web site development training based upon behavioral modeling method of instruction was conducted with sixteen teachers. The training created a positive and significant difference on the participants' web attitude, web self efficacy and perceived web usefulness scores. Although the post training scores of perceived web enjoyment and behavioral intention to use the web were higher than the pre training scores, the differences were not significant. The results are encouraging and suggest that teachers should involve more in design and development of web based materials to help students to learn.
