Purpose: Introduction: One of the most recent problems of the technology era is the use of extreme or addiction to the Internet, which has caused mental and social disorders, especially in young people. The present study aimed to investigate the degree of dependence, recognition of the relationship and the prediction of the mental health of Internet user students based on Dependence on the Internet Method: This research was a descriptive and correlational study. The population included students aged 14 to 18 years old in Baku and Tehran in 2015. The samples were selected by cluster sampling method. 250 students using the internet were selected from Baku and 250 students using the internet were selected from Tehran. To collect data, the Young’s Internet Addiction Test (IAT) and Goldberg’s General Health Questionnaire (GHQ) were used and data analysis was performed at two descriptive (mean, percentage, standard deviation) and inferential levels ((Regression and Pearson). Findings: According to the level of Internet dependency, 43.4% were mild and 24.8% moderate and 23.4% were severe addicts and internet addicts. The level of internet dependency is a positive and significant predictor of general health (R2 = 0.38). Physical health (R2 = 0.32) is anxiety (R2= 0.43) and depression (R2 = 0.39), but between internet dependency and social function is not significant. Conclusion: The level of internet dependency predict mental health components (physical health, anxiety and depression) but is poor in explaining social functioning. There is a positive and significant relationship between the level of Internet dependency and physical health, anxiety and depression of Internet user students.

Purpose: The using an interactive approach in sciences education can improve its learning. Therefore, the current research was conducted with the aim of identifying the dimensions and components of sciences education based on an interactive approach with an emphasis on the nature of science. Methodology: This study in terms of purpose was applied and in terms of implementation method was qualitative. The current research population was university students and teachers of basic sciences who were familiar with the subject, which number of 15 people of them were selected as a sample according to the principle of theoretical saturation and with the purposive sampling method. The data was collected by the in-depth semi-structured interview method and its validity was confirmed by the triangulation method and its reliability was obtained by the agreement coefficient method between two coders 0.86. The data were analyzed by open, axial and selective coding method in MAXQDA software. Findings: The findings showed that for sciences education based on an interactive approach with an emphasis on the nature of science were identified 48 concepts in 16 categories and 4 themes; So that 4 themes were included quality-orientation in the sciences education system (with 3 categories of quality evaluation in the educational system of formal education, efficiency of the educational system for science education and lack of effectiveness of science education programs in the formal education system), strategic management of the education system of formal education (with 6 categories of trust to abilities and plans of policymakers, institutionalizing the principles of science education, intra-group and institutional collectivism, developing the structure of an educational implementation system for logical thinking, keeping pace with global developments and designing science education programs for students), proposed solutions for designing the science education system based on the interactive approach (with 3 categories of students' participation in education, emphasis on strengthening the spirit of independence of students and logical education and its place in modern education) and challenges of the formal education system in the field of sciences education (with 4 categories of identity and its place of science in the educational system, argument-oriented and having a critical view, macro structure and institutional level of formal education and criticism to the educational system of current education structure in schools. Conclusion: Based on the results of the current research and the identified dimensions and components for sciences education based on an interactive approach with an emphasis on the nature of science, experts and planners of the educational system can take an effective step towards improving the sciences education based on an interactive approach by improving its dimensions and components.
