ارزیابی روان سنجی نسخه انگلیسی ابعاد نگرش نسبت به ابزار علمی با جمعیتی از آموزگاران ابتدایی آمریکا

The purpose of this study was to review the development and evolution of the Dimensions of Attitudes toward Science Instrument (DAS), translate the DAS into English, and examine its psychometric properties with a U.S. sample of pre-service and in-service elementary educators. After translation and expert review, the DAS was administered to a sample of 300 U.S. in-service and pre-service teachers. Confirmatory factor analysis and fit indices values supported a seven-factor theoretical model. The entire DAS was found to have good internal consistency. This study confirmed the DAS is a valid instrument for a U.S., English-speaking elementary education teacher population.
