Research Findings: This study explores the beliefs, self-reported practices, and observed practices of Turkish preschool teachers toward children’s peer relationship problems as well as the gap between their beliefs and practices. Five female teachers of 5-year-old children were selected as participants for this multiple case study. Approximately 79 hr of observation was conducted on the children’s daily routines and activities in a natural classroom environment, which specifically included the teachers’ problem-solving strategies while confronting peer relationship problems. The participants were also interviewed regarding their beliefs and strategies for solving peer relationship problems. The findings of this qualitative investigation indicated that the teachers’ beliefs and self-reported practices included both teacher- and child-related factors. However, the observed practices included several teacher-initiated strategies; child-initiated strategies appeared, albeit less than teacher-initiated ones. This affirms the teachers’ stress on children’s role in managing peer problems. Although some of the teacher practices and beliefs were consistent, certain inconsistencies may indicate the presence of external constraints. Practice or Policy: The results of this study highlight the importance of teacher education programs providing preservice and in-service teachers with the knowledge and skills required to understand children’s peer relationships, guide their interactions, and apply appropriate intervention strategies for various peer relationship problems.  相似文献

This study describes the beliefs, self-reported practices and actual practices related to child-centred education of five female preschool teachers in Ankara, Turkey, and assesses the consistency between the participants’ beliefs and practices. Data were collected through interviews, classroom observations and document review. The results indicated that the participant teachers’ beliefs and practices as expressed through instructional activities, relationships, behaviour management, assessment, parental involvement and self-reporting were partially parallel to the child-centred education philosophy. Also, there was only partial consistency between teachers’ beliefs about, self-reported practices of and actual practices of child-centred education.  相似文献

The purpose of this study was to describe to what extent four preschool teachers in Turkey have developmentally appropriate beliefs and practices related to two dimensions of classroom management. The participants of the study were four female teachers working in Ankara. The data of this study were collected through a demographic information protocol, interviews, classroom observations, and a document review. The findings of the study showed that preschool teachers’ beliefs were closer to developmentally appropriate practices than their self-reported and actual practices. Also, teachers’ actual practices were mainly influenced by the physical characteristics of the schools and children’s characteristics.  相似文献

The aim of this study is to investigate if a semester-long course on gender equity in education has an impact on the attitudes of preservice teachers toward gender roles. To this end, a pretest–posttest analysis is carried out in a state university in Ankara, Turkey, employing a sample of 133 preservice teachers; 33 of whom had taken the course and 100 of whom had not. The results reveal that the course has a substantial impact on the attitudes of the preservice teachers. Indeed, the attitudes of the teacher candidates taking the course change considerably at the end of the semester, developing more favorable attitudes toward gender issues.  相似文献

A new synthetic method is described here to obtain α, β-unsaturated ketones from alkenes through a sequence involving: (1) cycloaddition of alkenes with dichloroketenc; (2) dechlorination of adducts; (3) acidpromoted ring-opening isomerization of cyclobutanones in CF3 CO2H.  相似文献

This study aims to explore preschool teachers’ attitudes toward science teaching and its impact on classroom practices through the frequency of science activities provided in the classroom. In addition, the study investigates if their attitudes are related to factors such as educational level, years of teaching experience, and the school type they work in. The present research was conducted with 292 preschool teachers who work in public and private schools in different districts of Ankara, Turkey. The data were collected by administering the Early Childhood Teachers’ Attitudes toward Science Teaching Scale. Our analyses indicate that there is a significant but weak link between preschool teachers’ attitudes toward science teaching and the frequency of science activities that they provide in the classroom. Further, while teachers’ characteristics such as educational level and experience are found to play an insignificant role on the overall measures of the scale, type of school appears to be a major factor in explaining the attitudes toward science teaching.  相似文献

In this paper, we propose a novel method for addressing the multi-equilibria consensus problem for a network of n agents with dynamics evolving in discrete-time. In this method, we introduce, for the first time in the literature, two concepts called primary and secondary layer subgraphs. Then, we present our main results on directed graphs such that multiple consensus equilibria states are achieved, thereby extending the existing single-state consensus convergence results in the literature. Furthermore, we propose an algorithm to determine the number of equilibria for any given directed graph automatically by a computer program. We also analyze the convergence properties of multi-equilibria consensus in directed networks with time-delays under the assumption that all delays are bounded. We show that introducing communication time-delays does not affect the number of equilibria of the given network. Finally, we verify our theoretical results via numerical examples.  相似文献
