Explain of Structural Equation Modeling (SEM) at Norms of Rural Housing Establishment

The purpose of this study is to explain the theoretical model of the norms of rural housing formation in cold and mountainous climatic area of Ardabil province. The housing issue is one of the most important issues that human beings have always had to deal with and have long been trying to address and find a decent answer. The study of the renovation and improvement of rural housing in Iran shows that Iran has 5,172,000 rural housing units that require about 63 percent of the rural housing, 3 million and 295,000 units, to be urgently rebuilt. About two percent of them, equivalent to 81,000 units, were rebuilt between 1997 and 2005. Since 2013, the number of rural housing reconstruction has fallen sharply to 200,000 units per year that covers only four percent of all rural housing. Recognizing that new rural buildings and structures are generally supported by government agencies and at the head of the Housing Foundation of the Islamic Revolution or, as practiced by the inhabitants, it has the form and form of urban housing that runs without regard to native architectural values; Values that have become over time and overwhelming test-errors to unwritten rules of construction in the village. Therefore, the strengths of the present study are the consideration of the values governing indigenous housing formed in the context of rural areas that have been discovered and applied by residents for many years. Values that the author call norm. In the present study was used the correlation method of Structural Equation Modeling (SEM) based on field studies and exploratory survey research. After explaining the cold and mountainous area of Ardabil province, the settlements of this area with altitude of 1500 to 2150 meters above sea level were identified from 176 villages, 85 villages with a population of more than 200 were randomly selected based on the statistics of the year 1395 at Statistical Center of Iran. Sample size According to Based on Klein's theory, a sample of 250 residents of the above-mentioned villages was selected by purposeful sampling to answer 50 questionnaire questions related to residents' views on housing development. (So, every village is a cluster and the inhabitants are members of those clusters). The reliability of the tool (questionnaire) using Cronbach's alpha was α = 0.905. After analyzing the path and regression, the direct and indirect effects of the variables on the norms of rural housing formation were investigated. The findings showed that the sum of regression coefficients was explained as 0.412 and the components such as: Similarity/Homogeneity in housing setting, Geographical/Climatic, Economic/Livelihood, Scale and Cultural/Traditional are factors that affecting the formation of rural housing in cold and mountainous climates of Ardabil province. Therefore, it can be concluded that the model predictive variables predicted 41% of the criterion changes and 59% were affected by the external variables. The results of this study illustrate three general principles. First, the scale/proportion component has a more important role in shaping rural housing than all components. Secondly, rural housing shaping is a cultural phenomenon. And thirdly, the form of rural housing is a function of the altitude of the high seas.
