This research aims to systematically review the distributed leadership studies with phenomenological designs in educational contexts to investigate their descriptive indicators, the characteristics of phenomenological research designs, their research focus, and outcomes. A systematic review approach was employed in this study to identify, evaluate, and summarize research evidence within the scope of the research questions. Of 39 publications extracted from Web of Science, Scopus, and Educational Resources Information Center, nine documents were included in the review upon implementing the inclusion and exclusion criteria. According to the results, the studies ranged from 2011 to 2024, and the majority were conducted in Turkey and the USA at the K-12 level in separate or combined designs. Regarding phenomenological design, the studies varied in treating phenomenology and reflecting diverse perspectives. For instance, a notable number of studies utilized the purposive sampling method to select participants. However, most of them differed in their analysis techniques. As for their research focus and outcomes, it was detected that the eligible studies generally focused on influencing factors, elements, and experiences about distributed leadership, and significant results were revealed through phenomenological lenses.

This study investigates the change in the mathematics teachers' noticing levels through modeling. The case study method obtained extensive, comprehensive, and in-depth data. The study used modeling activities, group activity solutions, semi-structured interview sheets, observation notes, and video and audio recordings as data collection tools. The framework developed by Estapa et al. (2018) was used to analyze the data and examine the ability of mathematics teachers to notice during the application process of mathematical modeling activities. In addition, van Es (2011) developed the framework to determine the level of teachers' noticing skills. Seven elementary school mathematics teachers participated in the study. As a result of the study, when the data were examined, it was found that the level of noticing skills of six of the seven teachers increased during mathematical modeling activities. At the beginning of the study, the teachers did not allow the students to understand and interpret the question, but they explained the question through presentation and guided the students. As the study progressed and the teachers noticed that their skill levels increased, they paid more attention to the students' thinking, tried to understand them, discovered new ideas that might emerge, and started focusing on students' mathematical thinking.

The purpose of this study is to examine the distribution of social values among adolescents. Random cluster sampling method was used in the research, and the participants consisted of a total of 690 students, 410 girls and 280 boys, who continued their education in high schools in Kırıkkale province during the 2023-2024 academic year. A descriptive screening model was used in conducting the research. Personal information form and a semi-structured form developed by the researchers were used as data collection tools in the research. In the analysis of the data, frequency (f) and percentage (%) were calculated using the SPSS 27.0 program and statistical methods. Multiple response tables and cross-tabulation tables were used to examine the distribution of values according to demographic variables. As a result of the research, it was determined that the participants considered respect, justice, trust, love, and patriotism values more important than other values respectively. The least important values were found to be contentment, cultural heritage preservation, humility, tolerance, and responsibility respectively.  Female students value empathy, male students value patriotism, and 10th graders value truthfulness and honesty. Adolescents with low perceived socio-economic status value independent and free thinking, those with low perceived academic achievement value cleanliness, and those with high perceived academic achievement value truthfulness and honesty more. According to these findings, it is thought that adolescents may not fully perceive national and spiritual values such as patriotism and cultural heritage preservation. Researchers are recommended to work on the definition and transmission of values to students.
