This study investigated the effect of implementing flipped classrooms on Iranian junior high school students' reading comprehension. To this end, 50 Iranian pre-intermediate students were choosen and randomly assigned into two equal groups; one experimental group (flipped classroom) and one control group (traditional classroom). After that, both groups were pretested through a reading comprehension test. Then, the researchers put the respondents of the experimental group in a flipped classroom. The flipped classroom was equipped with Internet, computer and projector. The students were required to read each text before coming the class and discuss it with their classmates. On the other hand, the control group was taught in the traditional classroom. Before teaching each text, the researchers provided background knowledge for the control group and after teaching each text, the students were required to answer some questions related to the text. The whole treatment lasted 8 sessions of 50 minutes. In the last session, the post-test of reading comprehension was administered. The results of paired and independent samples t-tests indicated that there was a significant difference between the post-tests of the experimental and the control groups. The findings revealed that the experimental group significantly outperformed the control group (p < .05) on the post-test.

The purpose of this study is to explore the effectiveness of a STEAM (Science, Technology, Engineering, Arts, Mathematics) -based curriculum on junior high school students’ scientific creativity. The main topic of the STEAM-based curriculum in this study is an ancient mechanical clock that was designed and produced by the authors’ team. Further, the main concept of the ancient mechanical clock is about a gear wheel. Hence, this study designed two stages of courses which were gear wheel science courses (2 weeks) and STEAM-based courses (2 weeks). A total of 62 junior high school students from two different courses participated in this study and were divided into a control group and an experimental group. This study adopted a counterbalance design. The control group joined gear wheel science courses first and joined STEAM-based courses second. In contrast, the experimental group joined STEAM-based courses first. Both groups were asked to complete a pre-test, a middle-test, and a post-test by completing the “Scientific Creativity Test (Cronbach’s α 0.87)”. The results from paired t-test analyses showed that control group students did not show significant differences in scientific creativity before and after joining the gear wheel science courses, but they got significantly higher scores after joining STEAM-based courses than before. On the other hand, the experimental group students got higher scores in scientific creativity after joining STEAM-based courses than before, and persisted in getting higher scores after joining the gear wheel courses than before. Furthermore, the results implied that the STEAM-based courses might help students maintain or continue their scientific creativity. Further discussion is provided.

Background: High mobile-phone dependency may cause cognitive, emotional, and academic impairments among students; hence, proper therapies should be performed to prevent the risk. Objectives: The present study aimed to investigate the effectiveness of the nomophobia therapy package on self-esteem and nomophobia symptoms in high school students. Methods: The research method was quasi-experimental with a pre-test, post-test, and follow-up design and a control group. The statistical population included all the students showing nomophobia symptoms who were in high schools in Isfahan in the academic year of 2018 - 2019. Using purposive sampling, we selected 30 students willing to participate in the project and randomly divided them into experimental (n = 15) and control (n = 15) groups. The research instrument included Nomophobia Questionnaire and Self-Esteem Questionnaire. The experimental group underwent eight sessions (75-minute sessions per week) of nomophobia therapy. The follow-up was performed after two months. Data were analyzed by descriptive and inferential statistics, such as mean, standard deviation, and repeated measures ANOVA. SPSS version 23.0 was further used to analyze the data. Results: The mean ± SD of the post-test scores of self-esteem and nomophobia symptoms were (19.26 ± 3.34) and (50.60 ± 5.07) in the experimental group and (13.46 ± 2.47) and (71.63 ± 8.47) in the control groups. The difference between the scores of the experimental and control groups in the pre-test was not significant (all P-values were > 0.05). Also, the post-test scores did not have a significant difference from the follow-up scores (all P-values were > 0.05). Nomophobia therapy effectively increased self-esteem in students with nomophobia symptoms in the experimental group (P = 0.0001). The training intervention sessions decreased the nomophobia symptoms of high school students in the experimental groups compared to the control group (P = 0.0001). Conclusions: According to research findings, nomophobia therapy was an efficient therapy for improving self-esteem and reducing nomophobia symptoms in students who suffer from the syndrome.
