INTRODUCTION: The learning organization model does not exist in the RCS of Tehran province based on knowledge management, innovative organizational culture and quality of work life as an important organization, during disasters, especially the Tehran earthquake. Therefore, the aim of the current study is to present the learning organization model in RCS of Tehran province. METHODS: This applied research was carried out with grounded theory approach. About 15 academic professors and experts of RCS of Tehran province were selected and studied using purposeful sampling method based on the theoretical saturation. Data were collected through semi-structured interviews. FINDINGS: In this research, the learning organization with five dimensions and 56 concepts were extracted. The dimensions of the learning organization include gaining experience, feedback and evaluation system, systemic thinking, collaborative and fast learning, creative thinking. CONCLUSION: According to the results, focusing on gaining experience with regard to the occurrence of disasters is one of the priorities of the RCS. The challenges that the RCS faces at the learning organization are such as repeating the problems of previous disasters in new disasters, failure to use documentation and experiences of previous disasters, early forgetfulness of disasters and long return period of some disasters, failure to transfer field and operational experiences, not learning from the bitter experiences of disasters, infringing and sometimes copying processes without considering operational experiences, lack of expert documentary maker or teams in disasters and finally many disasters and little documentation. RCS can take action to manage these defects by implementing the learning organization model.

INTRODUCTION: Considering the location, the frequency of faults and the probability of earthquake, district 20 is distinguished from other areas as the most dangerous region of Tehran. Due to the uncertainty of the time of the previous destructive earthquake, the probability of activation of these faults is very high. METHODS: Regarding the exploratory nature of this research, the environmental scanning technique was used, and due to the dominant approach of this research, which is future research, the Delphi technique was used. Structural analysis has been used in MicMac software to analyze data. FINDINGS: The results of the dispersion of the variables indicate the instability of the system in the studied area, and accordingly, five categories of variables were identified. CONCLUSION: The results showed that based on the quantitative analysis of the Scenario Wizard software, three golden, static and crisis scenarios were obtained for the 2051 horizon of district 20, which is the most valid scenario related to the static scenario.

As a possible and influential factor in academic success, student growth mindset has recently received attention. However, the number of the studies concerning the effects of growth mindset on language skills in the context of Iran is not considerable and no study has specifically examined the influence of growth mindset on Iranian EFL learners’ vocabulary development. To fill this gap, this study was conducted in order to investigate if the intervention has any significant effects on Iranian EFL learners’ vocabulary development compared to those who do not receive such intervention. A quasi-experimental design in the form of pre- and posttest was used in this study. To homogenize the participants in terms of their proficiency, OQPT was used. Subsequently, out of 78 learners, sixty Iranian intermediate language learners were randomly assigned into two groups of control group receiving conventional vocabulary training and experimental group receiving a growth mindset intervention besides the conventional method for vocabulary learning. Vocabulary knowledge of the students was tested with the help of a vocabulary knowledge test that was specifically prepared and developed by researchers. To investigate if using growth mindset intervention had positive effects on learning English vocabulary by the learners in each control and experimental groups, two sets of paired-samples t-test were conducted. Afterwards, to explore which method had been more effective, the mean scores of the posttests of the control and experimental groups were compared by executing an independent two-sample t-test. The results revealed that implementing growth mindset intervention had positive effects on vocabulary development of EFL learners. Accordingly, this study has pedagogical implications for EFL teachers and students, as well as material designers.
