تحليل ساختار عاملي مقياس «توان پاسخ‌گويي به محيط» در مدارس دولتي

Factor Structure Analysis of Power of Response to Environment Scale in Public Schools of Shiraz

هدف كلي از انجام اين پژوهش، تحليل ساختار عاملي مقياس توان پاسخگويي به محيط در مدارس دولتي شيرازبود. ابزار پژوهش مقياس توان پاسخگويي به محيط ترك‌زاده و نكومند (2015) و مشتمل بر 19 گويه با طيف ليكرت است و شامل سه زيرمقياس مفهومي، ساختاري و عملكردي مي‌باشد. جامعه آماري پژوهش شامل كليه معلمان مدارس ابتدايي و متوسطه دولتي شيراز بود كه با روش نمونه‌گيري تصادفي- طبقه‌اي (برحسب دوره تحصيلي) و براساس فرمول كوكران تعداد 369 نفر انتخاب گرديدند. به منظور سنجش روايي پرسشنامه از دو روش تحليل گويه و تحليل عامل تاييدي مرتبه اول و دوم و جهت سنجش پايايي آن نيز از روش آلفاي كرونباخ استفاده شد. نتايج تحليل گويه حاكي از همبستگي معنادار هر يك از گويه ها با زير مقياس بعد مربوطه بود. نتيجه تحليل عامل تاييدي مرتبه اول و دوم نيز نشان داد كه هر يك از گويه ها از روايي بالايي براي تبيين بعد مربوطه و براي تبيين توان پاسخگويي به محيط برخوردار مي باشند. همچنين براساس مقادير آلفاي كرونباخ، پايايي مقياس و زيرمقياس‌هاي مربوطه، مطلوب ارزيابي شده است. براين اساس از اين مقياس مي‌توان براي سنجش توان پاسخگويي مدارس به محيط بهره گرفت.

The main aim of this study was to Factor Structure Analysis of Power of Response to Environment Scale in Public Schools of Shiraz. Research instrument of Torkzadeh and Nekoumand of Power of Response to Environment scale (2015) and consists of 19 items with a Likert spectrum, and includes three sub-scales; conceptual, structural and functional. population included all primary and secondary school teachers in Shiraz of whom 369 people were selected by random-stratified sampling method (based on the educational course) and Cochran’s formula. To measure the validity of the questionnaire, two methods of cluster analysis and first order and second order confirmatory factor analysis were used and also Cronbach's alpha method was used to measure its reliability. Results of the item analysis indicated that each items has a significant correlation with the sub-scale of corresponding dimension. Result of the first and second order confirmatory factor analysis showed that each Items had a high degree of validity for explaining the corresponding dimension and Response to Environment. Also, based on the Cronbach's alpha values, the reliability of the scale and the corresponding sub-scales is desirable. Accordingly, this scale can be used to measure schools' power of response to environment.
