The causal model of Cognitive concentration restoring on visual Permeability of educational spaces.

Mental focus is one of the main conditions for learning and academic achievement, which can be reconstructed by visual permeability and the ideal visual communication of classrooms with the outlook. Accordingly, the present study aimed to investigate the effect of visual permeability types on the basis of out landscape content on rehabilitation of mental concentration of students. The statistical population of this study was all students in the second section of high schools in Shiraz, aged 16 to 18 years, who were randomly selected as multistage cluster sampling (in each group of 15) ) were chosen. Subjects were evaluated by a questionnaire and psychological test in two stages before and after the intervention, and the totality of data was analyzed based on the paired t-test to find a meaningful relationship between visual permeability and cognitive mental restoration of students. The results of this research show that students' mental focus after conducting their activities can be greatly improved through visual access to the natural landscape of the outside environment. However, windowlessness in the classroom and the periphery of the physical elements have the least effect on restoring their mental concentration, respectively.
