Investigating the effective factors on the decision-making power of high school managers in order to present a model for improving decision-making power (a case study of the first high school in Khuzestan province)

The purpose of this study was to provide a model for developing managers' decision-making power and determining solutions to achieve the desired situation. The method of the present study was a qualitative and quantitative exploratory mixture based on grounded theory. In this study, according to the classification model with emphasis on qualitative data, a sequential integrated exploratory method was used to combine qualitative and quantitative data. The statistical population in the qualitative section consisted of 15 experts familiar with the subject of research. Also, in a small part of the statistical population, there are 2147 principals of first secondary schools in Khuzestan province, of which 326 (176 female and 150 male) were randomly divided into four sections using cluster sampling method (divided into four sections). North, south, east and west) were selected from regions (Izeh, Dehdez, Baghmalek, Ahvaz, Mahshahr, Dezful, Abadan and Khorramshahr). To collect data, two closed-ended and open-ended decision-making questionnaires were used to improve decision-making power.
