This research, tries to develop an attitude scale (educational access schemes (EAS) for SS) which determines the approaches of secondary students for environment. First 400 secondary students were invited to write a composition named "The importance of environment and its position in our lives". The compositions were examined one by one and a pre-pre-form as a draft that has 50 items was composed. This form was given to 5 teachers who are expert in their areas for the availability of extent, appearance, criterion and structure. In the result of experts' ideas after necessary corrections, a pre-scale that has 20 items was revealed in different size. Finally, this pre-scale was practiced upon 150 students who had geography lessons at to secondary schools in 2010/2011 educational year. With the help of this research's datums, for appointing the index of material detaching, independent t test is done to data. For determining structure validity of scale, factor analysis is done to data. Looking at two tailed significance, items that have value more than p less than 0.05 are abstracted from the scale. for the reliability of scale, Cronbach [alpha] (0.811) is calculated. the scale's ability to distinguish students with different attitudes was found to be statistically significant (p less than 0.05). (Contains 8 tables.)
