The Effects of Metacognitive Scaffolding on Scientific Concept Learning in Senior Primary Students in the Context of Virtual Scientific Inquiry: An Empirical Study
Get PDF Scientific concept study is an essential component of science education. A virtual scientific inquiry platform is an effective device for facilitating students grasping scientific concepts through inquiry-based learning. In a virtual scientific inquiry setting, metacognitive scaffolding that integrates the “predict-observe-explain” (POE) strategy can play an exceptionally significant role, given the absence of face-to-face tutoring from the teacher. Adopting experimental research design, this study seeks to investigate the effects of metacognitive scaffolding on scientific concept learning in senior primary school students in the context of virtual scientific inquiry
Artificial Intelligence and Your Life: The Problems We Must Face
Get PDFArtificial intelligence (AI) is transforming human life at an unprecedented pace. From revolutionizing industries and improving health outcomes to shaping how we interact with the world and each other, AI technologies are deeply embedded in modern life. While these systems bring powerful benefits, they also pose serious problems that demand urgent attention. This essay explores key issues related to algorithmic bias, loss of privacy, job displacement, psychological impacts, social inequality, environmental concerns, and inadequate governance. It highlights that as AI continues to evolve, societies must establish ethical frameworks, regulatory policies, and inclusive design processes to ensure AI technologies serve the collective good. Failing to face these problems now may result in long-term consequences that compromise human dignity, autonomy, and societal cohesion
Is Carbon Dioxide the Real Reason of Global Warming?
Get PDFGlobal warming has emerged as one of the most pressing challenges of the 21st century, with carbon dioxide (CO₂) often identified as the primary driver due to its heat-trapping capabilities. However, the dominance of carbon-centric narratives has overshadowed other potentially significant contributors such as methane, nitrous oxide, water vapor, aerosols, land-use change, and systemic feedback loops. This hypothesis article explores whether carbon is truly the main culprit behind global warming or if it is a proxy for a more complex web of factors. Through a multidisciplinary lens, it assesses scientific evidence, policy influence, climate modeling, and emerging research to question carbon's centrality. The article does not deny carbon's role but posits that focusing too narrowly on CO₂ may hinder comprehensive climate action. By re-evaluating the relative contributions of different forcings and amplifiers of warming, this analysis seeks to refine our understanding of climate dynamics and inform more holistic mitigation strategies that reflect the interconnected nature of Earth’s systems
Learning beyond the Classroom: The Value of Informal Learning Environments
Get PDFThe learning environment is a crucial factor in successful learning. Traditionally, only formal learning environments, such as schools and other educational institutions, have been accepted as educational settings, where educational activities are well-organized, following established curriculum programs and teaching objectives. Often disregarded is the fact that from the point of view of lifelong learning, most of our learning takes place in informal learning environments (Sefton-Green, 2004)
Prediction-Observation-Explanation (POE): An Effective Approach to Science Education
Get PDFPrediction-observation-explanation (POE) as a teaching strategy was advanced by Australian researchers White and Gunster in 1992. It has been primarily adopted in science education and project-based learning. With POE, the students develop the understanding of a specific scientific concept through the exploratory process consisting of hypothesis (prediction), experimentation (observation), and analysis/presentation (explanation) (Yurtyapan & Kandemir, 2022). Each of the three steps of POE has its own purpose (White & Gunstone, 1992; Nalkiran & Karamustafaoglu, 2020; Baydere, 2021). “Prediction” is for the students to make hypotheses about inquiry on a concept or an event in question and give their justifications. This step is to awaken the students to prior knowledge relevant to the new concept and identify possible gaps or misconceptions in them. “Observation” is for the students to observe the inquiry process of the concept or event. The teacher may present the concept or event through explanations, demonstrations, or experiments, and the students are required to record observations before, during, and after the experiment. “Explanation” is for the teacher to elaborate on the concept or event and give explanations of the discrepancies between the students’ predictions and observations, in order to enhance their grasp of the subject matter
The Relationship between Principal Authentic Leadership and Teacher Knowledge Sharing: An Empirical Analysis Based on the Self-Determination Theory
Get PDFTeacher knowledge sharing is a process in which teachers collaborate to boost their understanding and construction of knowledge by integrating fragmentary knowledge owned by individuals into a shared knowledge system. It helps promote common development in teachers as well as enhance the school’s quality of knowledge base as an educational community. Nevertheless, the teacher may tend to keep their knowledge private to maintain their professional distinctiveness. Also, educational and instructional expertise is often interwoven into the education process, and its implicit nature is an impediment to its sharing. Hence, teacher knowledge sharing has become a pronounced issue in modern school management. Recent research in this area reveals that the principal leadership style has a significant impact on the teachers’ knowledge sharing behavior. This study investigates the relationship between principal authentic leadership and teacher knowledge sharing, as well as its influencing factors, from the perspective of the self-determination theory
The Effect of Hot Conceptual Change on Students’ Views on the Nature of Science
Get PDFThis study aims to investigate the effect of the teaching model developed for hot conceptual change on middle school 7th-grade students’ understanding of the Nature of Science (NOS) aspects. In this qualitative and exploratory study, activities were carried out with 24 students of two classes in a village school in the South Marmara region using a pretest-posttest control group quasi-experimental design. Students in control (inquiry-based learning-IBL) and experimental (hot conceptual change based on IBL) groups used instructions for teaching the NOS topics in the 7th-grade light unit. The pre-test and post-test data on the NOS were obtained by the Opinions on the Nature of Science Questionnaire (ONSQ). In the analysis of ONSQ data, students’ views on the aspects of the NOS were scored according to the adequate (3), variable (2), and weak (1) categories. These scores were converted into gain scores and considered in the comparison between the groups regarding those aspects. Semi-structured interviews were conducted with two students from each group before and after the implementation. The gains related to NOS aspects obtained with the instructions carried out for seven weeks were presented and results were discussed in the context of the literature on hot conceptual change, IBL, and NOS. Finally, suggestions were made for new research and teaching practices for teachers
Accelerate Self-Catabolism of Adipose Tissue: A Promising Way for Weight Loss
Get PDFObesity is a multifaceted global health concern associated with numerous chronic diseases, including cardiovascular conditions, type 2 diabetes, and certain cancers. Traditional weight loss strategies—such as caloric restriction, exercise, and pharmacotherapy—have yielded inconsistent results for many individuals. A promising alternative lies in the body's own capability to mobilize and catabolize adipose tissue. This hypothesis article explores the concept of accelerating self-catabolism of adipose tissue as a targeted and efficient method for sustainable weight loss. Drawing from advances in metabolic physiology, hormonal signaling, mitochondrial function, and gene expression, the paper posits that enhancing lipolytic pathways, modulating adipokines, and leveraging brown adipose tissue (BAT) thermogenesis could synergistically increase energy expenditure while reducing fat mass. I hypothesized that integrated interventions, including selective pharmacologic agents, thermogenic stimulation, and intermittent fasting, to activate endogenous fat-burning mechanisms. Ultimately, this approach may redefine obesity treatment paradigms by transforming fat tissue from a passive energy store into an active agent of weight loss
