The purpose of this study was to design and validate the environmental curriculum framework based on the upstream documents in the middle school, which was carried out using a qualitative-quantitative method with exploratory design in two sections. The research population in the first section of the research was upstream documents. The sampling method from this population was criterion-based. The data collection tool comprised a checklist and taking notes whose validity was assessed and approved by experts, masters, and professors. The output of this section was the environmental curriculum framework in the format of four elements of the curriculum (purpose, content, method, evaluation), which was used to validate the 42-item questionnaire. The validity of the questionnaire approved from the experts' point of view and reliability by Cronbach's alpha coefficient. The statistical population of the study in the validation section comprised 2259 people of the experts and masters of the social sciences, experimental sciences, and Farsi literature from six districts of education in Isfahan in the academic year of 2018-19, of which, 329 people were selected by categorized relative random sampling. The data obtained from this section were analyzed using confirmatory factor analysis method using Lisrel software. The results showed that the fitness was appropriate for the proposed model based on the indexes (X2/df=1.947), (GFI = 0.95), (AGFI = 0.90), (RMR = 0.81).

The present study was conducted to recognize and analyze the Massive Open Online Course (MOOC) aesthetics for sustainable education. For this purpose, two methods of the exploratory search (qualitative) and the questionnaire (quantitative) were used for data collection. The research sample in the qualitative section included the electronic resources related to the topic and in the quantitative section, 36 experts in the field of the distance education planning from the virtual learning environments and universities were selected voluntarily. The content analysis method was used to analyze the qualitative data and weighted average and Friedman's test was used to analyze the survey data for content analysis. The qualitative results of the study showed that the aesthetics of the MOOC should have a visual attraction in terms of the learner dimension, and they should be attractive and enjoyable in terms of the content dimension and regardless of any constraint, they must be linked to the natural environment regarding the dimension of the teaching organization and educational environment, indicating the equal effect of each of the four dimensions (the learner, content, teaching organization, and educational environment) of distance education. Quantitative results obtained from the viewpoints of the experts in the field of the distance education on the aesthetics of the MOOC showed that they can be assessed in the dimensions of the content, educational environment, and the teaching organization that will have a significant and special effect on the qualitative results on the MOOC aesthetics.

Sustainable agriculture depends on the use of eco-friendly technologies by farmers.This research was conducted to identify and evaluate farmers' intent to use pheromone traps for controlling rice pests in paddy farms of Simorgh County, Mazandaran Province. Methodologically, this research was carried out using a questionnaire-based survey. The statistical population of this research included 1,500 farmers in 29 villages of Simorgh County, in which 204 farmers were selected using Cochran formula. Samples were selected using proportionate stratified random sampling. The formal and content validity of the questionnaire was based on experts' opinion and its reliability was calculated based on Cronbach's alpha coefficient. Cronbach's alpha coefficient was calculated between.70 and.80 for the scales of research variables. Data were analyzed using SPSS 20 software. The results showed that 33.8% and 16.7% of the respondents intended to use pheromone traps relatively strongly and strongly, respectively. The regression path analysis method was used to identify the direct and indirect effects of independent variables on the final dependent variable of intention to use the pheromone traps. The results of the path analysis showed that subjective norms had the most direct effect on the dependent variable (intention to use) (r=0.947). In terms of total direct and indirect effects, the perceived barrier to use with a total impact of 1.373 was in the first place. According to beta coefficients, the variables of attitude, behavioral control, and subjective norms had total effects of 0.391, 0.690, and 1.076, respectively.
