This ethnographic study explored aspects of how the natural sciences were represented in a Reggio Emilia‐inspired laboratory preschool. The natural sciences as a discipline—a latecomer to preschool curricula—and the internationally known approach, Reggio Emilia, interested educators and researchers, but there was little research about science in a Reggio Emilia classroom. The current research aimed to gain insight into natural science experiences in a Reggio Emilia‐inspired classroom. To gain in‐depth information, this inquiry‐based study adapted a research design with ethnographic data collection techniques (i.e., interview, observation, document/artifact collection, and field‐notes), namely Spradley's Developmental Research Sequence Method, which was a well‐known, pioneer ethnographic method. The data were analyzed from an interpretive perspective using multiple lenses. These lenses included Spradley's DRS for the classroom culture, Corsaro's peer culture theory, the Reggio Emilia approach, and Ohio's Early Learning Content Standards. The study involved 18 preschoolers, 10 teachers, and a program director. The results indicated that the Reggio Emilia‐inspired preschool offered a science‐rich context that triggered and supported preschoolers' inquiries, and effectively engaged preschoolers' hands, heads, and hearts with science. The natural sciences learning in this Reggio Emilia‐inspired preschool classroom met and exceeded some of Ohio's prekindergarten standards. The results suggested that the Reggio pedagogy, grounded in inquiry, is compatible with science education goals. © 2010 Wiley Periodicals, Inc. J Res Sci Teach 47: 1186–1208, 2010 相似文献

In this study, we aimed to determine the early cognitive and home environmental predictors of reading in Turkish-speaking children. A total of 362 children participated in the study. We monitored the children for 3 years and assessed the home environmental variables and cognitive skills in kindergarten, reading fluency at the end of the first grade, and reading comprehension at the end of the second grade. We found that home literacy environment and socioeconomic status predicted early literacy skills in kindergarten as they also predicted reading fluency and reading comprehension through early literacy in later years. In addition, we found that phonological awareness, letter knowledge, and rapid naming predicted reading fluency, while language and verbal working memory predicted reading comprehension. The results of the study showed us that it is important to consider reading and reading comprehension in Turkish-speaking children holistically, together with cognitive skills and home environmental variables. 相似文献

This article examines the effects of social capital on the likelihood of dropping out from the compulsory education system (Grades One through Eight) in Turkey. It focuses on the question of whether school-related social capital can provide the means to stay in school in the presence of risk factors such as socioeconomic status, race, or gender that cannot be easily modified. Despite major progress in enrollment rates due to policies enacted in recent years, the overall drop-out rate in compulsory education is close to 15% in Turkey. Data collected from 764 student–mother pairs show that drop-outs are exposed to higher number of social risk factors. We further illustrate that school-related social capital, as measured by quality of in-school teacher–student interactions as well as parental involvement in school, significantly and positively contributes to adolescents’ likelihood of staying in school even in the presence of severe social inequalities. 相似文献

The ongoing changes, updates, and upgrades of the Smart Grid infrastructure open up new cybersecurity challenges whose successful and satisfactory handling is a vital necessity for a viable future of these initiatives. The characteristic of the Smart Grid that leads to physical damage and cascading power failures amplifies the severity of security breaches. A set of recent successful Distributed Denial-of-Service (DDoS) attacks on the Internet, facilitated by the proliferation of the Internet-of-Things (IoT) powered botnets, shows that the Smart Grid may become the target and likely victim of such an attack, potentially leaving catastrophic outage of power service to millions of people. In this paper, under a hierarchical data collection infrastructure we propose a general and scalable mitigation approach, called Minimally Invasive Attack Mitigation via Detection Isolation and Localization (MIAMI-DIL), based on an online and nonparametric anomaly detection algorithm which is scalable and capable of timely detection. We provide a proof-of-concept by means of simulations to show the efficacy and scalability of the proposed approach. 相似文献

In this study, we examine how bilingual students in elementary school use their languages and what this means for their meaning-making in science. The class was multilingual with students bilingual in different minority languages and the teacher monolingual in Swedish. The analysis is based on a pragmatic approach and the theory of translanguaging. The science content was electricity, and the teaching involved class instruction and hands-on activities in small groups. The findings of the study are divided into two categories, students’ conversations with the teacher and student’s conversations with each other. Since the class was multilingual, the class instruction was carried out in Swedish. Generally, when the conversations were characterised by an initiation, response and evaluation pattern, the students made meaning of the activities without any language limitations. However, when the students, during whole class instruction, were engaged in conversations where they had to argue, discuss and explain their ideas, their language repertoire in Swedish limited their possibilities to express themselves. During hands-on activities, students with the same minority language worked together and used both of their languages as resources. In some situations, the activities proceeded without any visible language limitations. In other situations, students’ language repertoire limited their possibilities to make meaning of the activities despite being able to use both their languages. What the results mean for designing and conducting science lessons in a multilingual class is discussed. 相似文献

This paper reports an analysis of the classroom management concerns of pre-service early childhood education (ECE) teachers prior to beginning their career and further examines the difficulties they experienced in classroom management in their first year of teaching and their coping strategies. Sixteen pre-service ECE teachers enrolled in the same teacher education programme were interviewed immediately before graduation, and were again interviewed at the end of the first and second semesters after they started to work in public schools. Phenomenological analysis was utilized for the data analysis. The findings revealed that all of the participants had a fear of being unable to manage their classes before starting their careers because they felt unprepared. However, they experienced fewer problems than expected after they started to teach. The teachers first tried to build trusting and close relationships with the children to create a peaceful classroom climate, while also attempting to empower the children by involving them in decision-making processes. In this way, the children became aware of the class rules and felt free in their actions within the limits of the rules. 相似文献

Clinical theory is replete with rich observations that the onset of walking engenders an enhancement of emotional expression in the infant. Yet, no empirical research exists on this subject. Moreover, the importance of normal timing variations in the onset of developmental transitions has not been a topic of investigation in most developmental research. In this naturalistic home study, "earlier" and "later" walking groups were delineated on the basis of timing of entry into this developmental transition. Age-held constant analyses indicated that earlier walkers and their mothers generally showed a rise in positive exchanges as well as "testing of wills" across the transition to walking. These changes were less clear for the later walkers. Differences were observed also between the two groups even prior to walking. These findings suggest that future studies should take account of timing variations in the onset of a developmental transition. 相似文献
