Design of an inventory for the evaluation of attitudes and teaching practices on sustainable development in physical educationTassi, Alexandra (Avtor) Adamakis, Manolis (Avtor) Karteroliotis, Konstantinos (Avtor) sportmeasurement reliabilityphysical education teacherssustainable developmentSDGsquestionnaireThis pilot study examines the content validity and reliability of an inventory designed to assess physical education teachers’ attitudes, perceptions, and teaching practices related to sustainable development. The inventory was developed by adapting two validated instruments: the Attitudes and Perceptions on Education for Sustainable Development scale and the Assessment Tool for Physical Education for Sustainable Development. These instruments underwent content and face validity evaluation before piloting. The study aimed to assess the inventory’s internal consistency using Cronbach’s α coefficients and its stability through a test-retest procedure. Thirty-two Greek physical education teachers (8 males, 24 females; M = 48.85 years, SD = 6.18) completed the inventory twice, with a 20-day interval. Reliability analysis indicated that Cronbach’s α coefficients for individual factors ranged from 0.70 to 0.87, demonstrating adequate internal consistency. Test-retest results confirmed satisfactory stability in most question categories. Findings suggest that the inventory is a valid and reliable tool for assessing sustainable development-related attitudes and practices in physical education, with minor refinements recommended for specific items before broader application. This study highlights the need for robust assessment tools to evaluate education for sustainable development, particularly in physical education, where fostering sustainability-oriented attitudes is essential for promoting corresponding teaching practices.20252026-03-11 08:59:32Članek v reviji180524UDK: 796.01ISSN pri članku: 1318-2269DOI: 10.52165/kinsi.31.1.69-83COBISS_ID: 239726595sl
