analysis of internal, external and institutional structure in the effectiveness of tourism education courses: a study based on confirmatory factor analysis

The overall purpose of this study was to analyze the factor structure of the scale of effectiveness of tourism education courses. the research method is descriptive methodology. the statistical population of the study included all participants in tourism education projects who were selected as a sample using simple random sampling based on cochran's formula of 223 people. a researcher-made tool was designed based on a three-dimensional model of internal, external and institutional effectiveness. the scale consisted of 3 subscales and 27 items from the likert five-choice range. in order to measure the validity of the scale, two methods of item analysis and confirmation factor analysis of the first and second order and to measure its reliability, cronbach's alpha method was used, which showed the desired validity and reliability of the instrument. the results of item analysis indicated a significant correlation between each item and the corresponding dimension subscale. the result of the first and second order confirmatory factor analysis also showed that each item has a high validity to explain the relevant dimension and to explain the effectiveness of tourism training courses. also, based on cronbach's alpha values, the reliability of the scale and related subscales has been evaluated as desirable. based on the findings of this study, it indicates that this scale can be used to measure the effectiveness of tourism education courses in internal, external and institutional dimensions. therefore, planners and officials can use it to determine the effectiveness of tourism training courses.
