Early research investigated the students understanding of science concepts using physical equipment, such as visiting labs and performing experiments but due to the advancement of new technology, students now can learn complex science concepts through advanced means, such as iPad, smart books and simulations. In Pakistan, interactive computer simulation program is rarely used for teaching at the early ages. The aim of the present study is to evaluate the effectiveness of the interactive computer simulation program PhET to teach weight and mass concepts to high school students. Quasi-experimental design was used to study the effect of the interactive computer simulation on students’ physics concepts. Study also explored the student’s engagement with simulation to exercise high order thinking skills. The experimental group was taught with the interactive computer simulation program, and the control group was taught with traditional teaching method. There were five lessons each week, and the program was used for a month. Pre- and post-tests were designed for both experimental and control groups. Independent sample t-tests showed that the difference was significant between the mean scores of the experimental and control groups after the experiment (p

In this study, to examine the change in individuals' critical thinking skills, a new unit was developed in which STEM was integrated. The outcomes of this 7th-grade unit were selected from related disciplines. During the learning process of the developed Force and Energy unit, it was aimed that individuals could make judgments by gaining critical thinking skills and evaluate events in a multi-dimensional way. In this study, which lasted for five weeks, the developed unit was used to conduct lessons with the experimental group (N=25) while the control group (N=25) was traditionally taught. The Critical Thinking Scales developed by Demir (2006a) were used in the research process. Before the implementation, no significant difference was found between the experimental and control groups regarding critical thinking skills, but after the implementation, a significant difference was observed in favour of the experimental group. When the scores obtained from the sub-scales (interpretation and explanation) were compared, a significant difference was found in favour of the experimental group. When the changes in the experimental and control groups were examined, there was no significant change in the control group students, but a significant change was found in favour of the experimental group. These changes occurred in the evaluation, Interpretation, and explanation sub-scales of the critical thinking scale.

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.

Conjugated linoleic acid (CLA) is a collective term for the positional and geometric isomers of a conjugated diene of linoleic acid (C18:2, n-6). The aims of the present study were to evaluate whether levels of hepatic α-tocopherol, α-tocopherol transfer protein (α-TTP), and antioxidant enzymes in mice were affected by a CLA-supplemented diet. C57BL/6 J mice were divided into the CLA and control groups, which were fed, respectively, a 5 % fat diet with or without 1 g/100 g of CLA (1:1 mixture of cis-9, trans-11 and trans-10, cis-12) for four weeks. α-Tocopherol levels in plasma and liver were significantly higher in the CLA group than in the control group. Liver α-TTP levels were also significantly increased in the CLA group, the α-TTP/β-actin ratio being 2.5-fold higher than that in control mice (p<0.01). Thiobarbituric acid-reactive substances were significantly decreased in the CLA group (p<0.01). There were no significant differences between the two groups in levels of three antioxidant enzymes (superoxide dismutase, glutathione peroxidase, and catalase). The accumulation of liver α-tocopherol seen with the CLA diet can be attributed to the antioxidant potential of CLA and the ability of α-TTP induction. The lack of changes in antioxidant enzyme protein levels and the reduced lipid peroxidation in the liver of CLA mice are due to α-tocopherol accumulation.
