These findings contribute to a better understanding of bullying in Turkish schools, emphasizing the negative effects of bullying involvement on health and well-being.

This study aims to determine the effect of learning activities conducted in accordance with the phenomenon-based learning approach on the metacognitive awareness level of students. Pre-test and post-test control group design of the experimental method was used. The application of the study was carried out in a sample of 60 students studying in the 7th grade of middle school in the 2019-2020 academic year. While "phenomenon-based learning approach" was implemented in the experimental group, traditional teaching was used in the control group. In this research, as data collection tool "metacognitive awareness" scale was used. The scores of the experimental and control groups obtained from the scale were compared to the dependent groups with the t-test, and when there was a significant difference between the students' pre-test scores and post-test scores, the effect size of the difference was found by looking at the Cohen's d value. In addition, when the pre-test scores of the students in the experimental group and the control group were taken under control, covariance analysis was conducted to determine whether there was a significant difference according to the post-test scores. According to the indications obtained at the end of the research teaching activities conducted in accordance with the phenomenon-based learning approach provided significant differences in the metacognitive awareness levels of the students in favor of the experimental group.

The purpose of this study is to determine the effects of teaching supported by self-regulated learning on students’ learning and studying responsibility. This research was carried out through “pre-test-post-test control group model”. The sample of the study consisted a total of 52 fifth grade students studying in two different classrooms of an urban primary school located in the West Black Sea Region in Turkey in the 2018-2019 academic year. This study was conducted for 4 weeks and the unit of “Culture and Heritage” in social studies lesson was covered. The learning and studying responsibility scale was used to collect the data. In the analysis of data, pre-test – post-test scores were compared by using t-test for dependent groups. In addition, in order to explain the power of relation, effect size (Cohens' d) values were calculated. The result of the study shows that teaching supported by self-regulated learning is effective and beneficial in students' learning and studying responsibility levels in favour of experimental group. This result demonstrated that teaching supported by self-regulated learning had positive effects on students' learning and studying responsibility.

The aim of this research is to examine some variables related to cyber bullying and cyber victimization in high school students. It was investigated whether there is a difference for cyber bullying and cyber victimization behaviours, in terms of gender, age, type of school, parents' education, having of computer/mobile phone/tablet, the frequency of using the internet and place where they are connecting to the internet. The study is conducted using a correlational method. Research group consisted of 1085 students. The age of the students in this study is between 14-17. For the analysis of research data, Mann-Whitney U test, Kruskal-Wallis test and Post-Hoc Mann-Whitney U test were applied. According to the findings of study, there is no significant difference for the cyber bullying grades in terms of parents' education, the types of school and place where students are connecting to the internet. There is no significant difference for the cyber victimization grades in terms of gender, age and mothers' education. Cyber bullying grades of 16 years old students are higher than the other age groups. State school students' cyber victimization grades are higher than private school students'. Additionally, for the period they use the internet, it was seen that cyber bullying and cyber victimization grades are higher for the students using the internet more than 3 hours. In terms of cyber victimization grades it was obtained that the grades of students connecting to the internet from a mobile phone are higher than the students connecting to the internet at home.
