  Experiences of Primary School Administrators in Relations with External School Stakeholders: A Phenomenal Study

  Satir, Selim; Kodan, Hulya

  The aim of this study is to reveal the experiences of primary school administrators regarding the functioning of social, cultural, and sports activities in their relationships with out-of-school environmental stakeholders. The study is qualitative in nature and employs a phenomenological research design. The study group consists of school administrators working in primary schools affiliated with the ... District of ... Province during the 2023-2024 academic year. The data were collected using a semi-structured interview form prepared by the researcher. Content analysis was used to analyze the data. The findings indicate that parents contribute in areas such as the provision of tools and materials; however, negative situations were also observed, such as perceiving activities as unnecessary. While the moral support of senior administrators was emphasized, serious problems such as discrimination also came to the fore. The contributions of local governments, such as transportation support, were highlighted; however, issues such as geographical discrimination driven by politics were also noted. Although political parties were found to provide material support to schools, political interference in education was emphasized as a negative experience. In relations with labor unions, material support was highlighted, whereas educational support was emphasized in relations with non-governmental organizations. It was determined that social media contributes positively to the functioning of various activities by increasing visibility, but it also creates negative effects, such as pressure to engage in constant sharing. Various recommendations were presented, including encouraging parents' active participation in social activities and developing support policies to prevent geographical and political discrimination.

  Civas, Ayse; Karakas, Seydanur; Bayrak, Burak; Akyüz, Beyzanur; Keçeci, Emire Bengisu; Özerd, Elif Beyza; Sönmez, Hatice Rumeysa; Asgarli, Tugay; Disli, Fatma Taeb; Yuca, Hafize

  This study provides a comprehensive phytochemical, elemental, and spectroscopic characterization of 26 species belonging to the Asteraceae family, several of which are endemic to T & uuml;rkiye and traditionally used in folk medicine. Qualitative screening revealed the widespread presence of flavonoids, saponins, tannins, and carbohydrates, while alkaloids and anthracene heterosides were entirely absent in all taxa. Among the species analyzed, Cichorium intybus, Cyanus depressus, Achillea arabica, and Cirsium davisianum exhibited the richest phytochemical diversity, suggesting strong biological potential. Quantitative evaluation showed that Klasea serratuloides possessed the highest total phenolic content (99.49 mu g GAE/mg extract), followed by Artemisia scoparia and Inula sarana, indicating notable antioxidant potential. Elemental analysis by ICP-MS demonstrated significant interspecies variation, with Centaurea armena, Centaurea arvensis, and Cichorium intybus containing elevated levels of essential macro- and trace elements such as K, Mg, Ca, Zn, and Se, whereas Helichrysum plicatum and Scorzonera ulrichii showed high Co and Se contents. Conversely, trace levels of potentially toxic elements (e.g., Al, U) were detected in some taxa, emphasizing the need for careful evaluation of their pharmacological use. FTIR analysis confirmed the presence of functional groups characteristic of phenolics, flavonoids, tannins, coumarins, and cardioactive heterosides, as indicated by distinct O-H (3200-3600 cm-1), C-H (2850-2950 cm-1), and C=O (1700-1650 cm-1) stretching bands. The combined interpretation of phytochemical and FTIR data underscores the chemical diversity and functional group complexity of these plant extracts. Overall, the results highlight the nutritional and pharmacognostic significance of several Asteraceae species, supporting their potential application in antioxidant, nutraceutical, and therapeutic formulations.

  Measuring of Metacognition in Problem-Posing: Standardization of the Metacognition in Problem-Posing Scale

  Öztürk, Mesut; Sarikaya, İsmail; Albayrak, Mustafa

  While research on metacognition in mathematics education has grown recently, it has primarily focused on problem- solving, with little attention given to problem-posing. However, problem-posing also involves complex metacognitive processes that warrant deeper investigation. This study addresses this gap by developing and validating a new instrument to assess metacognition in problem-posing among middle school students. The metacognition in problem-posing Scale is an eight-item measure encompassing three factors: planning, monitoring, and evaluation. The study was conducted using a scale-development design within a survey research framework, and data were collected through a two-stage simple random sampling. Psychometric analyses confirmed the scale’s reliability and its construct validity. The metacognition in problem-posing Scale offers a promising tool for exploring students’ metacognitive engagement in problem-posing tasks and has potential applications in both research and classroom settings.

  Bioactive profile and mineral composition of fruit extracts from four wild hawthorn (Crataegus spp.) species

  Çakır, Özlem; Çınar Topçu, Kübra; Sefali, Abdurrahman; Bayyiğit, İshak; İlhan, Gülçe; Singh, Jyoti

  This study compared the antioxidant capacity, total phenolic content (TPC), phenolic composition, lipid oxidation level, and mineral profiles of extracts obtained from four wild hawthorn species (Crataegus tanacetifolia, C. orientalis subsp. orientalis, C. orientalis subsp. szovitsii, and C. monogyna) collected from northeastern Türkiye. Significant interspecific variations were observed in DPPH, FRAP, and CUPRAC assays. While C. monogyna had the highest reducing capacity and TPC, C. orientalis subsp. szovitsii had the highest DPPH activity. Ultra-high performance liquid chromatography coupled to tandem mass spectrometry analysis showed that catechin, epicatechin, chlorogenic acid, and quinic acid were the major phenolics, and were particularly abundant in C. monogyna. Despite having a high phenolic content, C. monogyna had the highest malondialdehyde level, indicating that phenolics alone were insufficient to fully inhibit lipid oxidation. Inductively coupled plasma-mass spectrometry mineral analysis detected high levels of K, Mg, and P in all species. Principal component analysis effectively distinguished the species based on their antioxidant, phenolic, and mineral profiles. Overall, hawthorn fruits were confirmed as valuable sources of natural antioxidants and essential minerals.

  The Effect of Inquiry-based Science Learning Supported By Augmented Reality On Scientific Process Skills and Academic Achievement in Preschool

  Arici, Faruk

  Inquiry-based learning (IbL) is widely recognized as an effective pedagogical approach in early science education; however, young learners often struggle to engage with abstract concepts and sustain inquiry processes. Augmented reality (AR) has the potential to address these challenges by enhancing interaction, visualization, and engagement in learning environments. Although previous studies have demonstrated the positive effects of IbL and AR separately, empirical evidence examining the combined impact of AR-supported IbL on preschool students’ academic achievement and scientific process skills (SPS) remains limited, particularly in early childhood science education. This study aimed to investigate the effects of AR-supported IbL, IbL alone, and the current preschool science curriculum on children’s academic achievement and SPS. In addition, participants’ perspectives on learning experiences, skill development, and instructional activities were explored. A mixed-methods design was employed with three groups: AR-supported IbL, IbL-only, and a control group following the existing curriculum. Quantitative data were collected using achievement and SPS assessments, while qualitative data were collected through repeated teacher observations and in-depth interviews conducted throughout the intervention. Results indicated that AR-supported IbL led to significantly higher academic achievement and SPS than IbL alone or the current curriculum. While IbL was more effective than the curriculum-based approach, integrating AR further strengthened inquiry cycles and particularly enhanced measurement, communication, and prediction skills. Observational and interview data supported these findings by revealing increased curiosity, engagement, and active participation. The findings suggest that integrating AR within inquiry-based pedagogical frameworks can substantially improve the effectiveness of preschool science education. Implications are discussed for curriculum design, teacher professional development, and the development of developmentally appropriate AR-supported learning environments.

  Examination of studies on scientific process skills in science education through bibliometric and content analysis

  Arici, Faruk

  This study presents a comprehensive analysis of academic research on scientific process skills (SPS) in science education using meticulously extracted data from the Web of Science (WoS) database. A holistic approach was employed in the research, integrating bibliometric analysis and content analysis to reveal general trends and thematic structures in the literature. Specifically, bibliometric analysis was employed to examine the most frequently cited studies on inter-author collaborations and keyword trends on SPS. Content analysis provides a unique contribution to our study by detailing the analysis of these publications. A distinguishing feature of this study is the use of a more extensive data set and a more extended period than previous studies, providing a more comprehensive picture of the evolution of research on SPS over time. The VosViwer bibliometric analysis software employs an array of analytical methods, including citation analysis, co-author analysis, keyword matching, and collaboration network analysis, to identify trends within the field. The analysis encompasses studies published from the inaugural study in 1992 through August 2024. The findings reveal a substantial increase in publications, with 2020 demonstrating the highest number of publications. In contrast, the average number of publications during the preceding five-year period was restricted to eight per year. Most of these publications are classified under "Education, Educational Research," with a smaller number falling under "Biology." This observation suggests that the primary focus of SPS research is within the educational context. Furthermore, the study revealed that publications in the SSCI and ESCI indexes are more prevalent, while there are fewer studies in the SCI-E index. The prominent researchers in this field include Kamisah Osman, Hatice Zeynep Inan, and Susan A. Kirch. A notable observation was Turkey's high ranking in terms of country distribution. This observation indicates that researchers have dedicated significant attention to the SPS in the context of science education. The most prevalent keywords in the analyzed studies were "SPS," "science education," "inquiry," and "assessment." Over time, there has been an upward trend in the use of terms such as "inquiry-based learning," "teacher education," and "elementary education." The most prominent academic journals in this field include the Journal of Research in Science Teaching and the International Journal of Science Education. Notwithstanding the strides made, the study underscores Turkish researchers' need to enhance their visibility and cultivate national journals to attain international standards.
