This exploratory study examines the background characteristics, socio-cultural values and pedagogical beliefs that entering student teachers bring with them into the faculties of education and explores their possible implications for teacher education in the Turkish context. The study comprised 18,226 first-year student teachers from 51 faculties of education who participated in the study by responding to a three-section questionnaire developed by the research team. Their responses indicate that students entering education faculties typically come from families of lower-middle socio-economic status living in urban areas, tend to possess more traditional than secular-rational values and have not yet formed clear pedagogical beliefs.  相似文献

This paper examines and discusses the profiles of applicants and entrants to the DGO (Dioplóma Gairmiúil san Oideachas) initial teacher education programme between 2000 and 2011. The DGO is the only initial teacher education programme in Ireland that is specifically designated to prepare student teachers for the second-level Irish-medium (SLIM) school sector. It is delivered entirely through the Irish language. This study examines data collected from all DGO applicants (N = 1002) between 2000 and 2011. Results show that demand for this programme has increased over the past decade. The academic quality of applicants has risen dramatically in recent years and 75% of successful applicants are female. The data show that a significant proportion of DGO applicants are native Irish speakers from Gaeltacht (areas in Ireland where the Irish language Gaeilge is the vernacular). There has been a severe shortage of applicants with qualifications in certain subject areas, in particular in Sciences, Mathematics and European languages. Drawing on findings from this study as well as on national statistics and educational policy documents, this paper discusses how changes to the DGO selection process may contribute to better meeting the staffing demands in SLIM schools in Ireland.  相似文献

The teachers' role in the integration of science and technology studies within the recent educational reform in Israeli junior high schools was addressed within a case study. Eight science teachers and three technology teachers participated in in‐service training courses and received individual tutoring. Data were obtained through school visits, interviews with management, teachers, and tutors. Pupils' performance on a science‐technology project was assessed by an achievement test and a questionnaire. Science teachers preferred to extend their content knowledge and didactic skills in science. Technology teachers lacked basic scientific knowledge. A realistic aim is to expose the science teacher to the field of technology, and the technology teacher to the realm of science, to the extent that will enable him or her to cooperate with the teacher in the parallel domain, rather than train a teacher to teach both. © 1999 John Wiley & Sons, Inc.

Are preservice teachers prepared to teach struggling readers?   总被引:1,自引:0,他引:1  
Reading disabilities such as dyslexia, a specific learning disability that affects an individual’s ability to process written language, are estimated to affect 15–20% of the general population. Consequently, elementary school teachers encounter students who struggle with inaccurate or slow reading, poor spelling, poor writing, and other language processing difficulties. However, recent evidence may suggest that teacher preparation programs are not providing preservice teachers with information about basic language constructs and other components related to scientifically based reading instruction. As a consequence preservice teachers have not exhibited explicit knowledge of such concepts in previous studies. Few studies have sought to assess preservice teachers’ knowledge about dyslexia in conjunction with knowledge of basic language concepts. The purpose of the present study was to examine elementary school preservice teachers’ knowledge of basic language constructs and their perceptions and knowledge about dyslexia. Findings from the present study suggest that preservice teachers, on average, are able to display implicit skills related to certain basic language constructs (i.e., syllable counting), but fail to demonstrate explicit knowledge of others (i.e., phonics principles). Also, preservice teachers seem to hold the common misconception that dyslexia is a visual perception deficit rather than a problem with phonological processing. Implications for future research as well as teacher preparation are discussed.  相似文献

This paper evaluates a widely used, low stakes, teacher peer-to-peer observation and feedback program under Randomized Control Trial (RCT) conditions. Half of 181 volunteer primary schools in England were randomly selected to participate in a two-year program in which three fourth and fifth grade teachers observed each other. We find that two cohorts of students taught by treated teachers perform no better on externally graded national tests compared to business as usual. However this masks large heterogeneity; in small schools, where there is only one class per grade, we find negative impacts of the training (0.1-0.18SD), whereas we find positive impacts in larger schools (0.06-0.17SD). We outline and explore potential mechanisms for this and conclude that centralised one-size-fits-all teacher training interventions may be harmful.  相似文献

We use a unique longitudinal sample of student teachers (“interns”) from six Washington state teacher training institutions to investigate patterns of entry into the teaching workforce. We estimate split population models that simultaneously estimate the impact of individual characteristics and student teaching experiences on the timing and probability of initial hiring as a public school teacher. Not surprisingly, we find that interns endorsed to teach in “difficult-to-staff” areas are more likely to find employment as public school teachers than interns endorsed in other areas. Younger interns, white interns, and interns who completed their student teaching in suburban schools are also more likely to find a teaching job, all else equal. Prospective teachers who do their internships at schools that have more teacher turnover are more likely to find employment, often at those schools. On the other hand, few of the characteristics of an intern's cooperating teacher are predictive of workforce entry. Finally, interns with higher credential exam scores are more likely to be hired by the school where they did their student teaching.  相似文献

The theory-practice debate has been a perennial issue in initial teacher education (ITE). By reporting a mixed-methods study in an ITE programme characterized by a university-based ‘theory-first’ approach in Hong Kong, this study offers useful empirical evidence to analyse the theory-practice issue. 346 student teachers of a BEd Programme participated in the quantitative survey, 15 of whom were interviewed. The quantitative findings showed significant positive correlations between three types of perceived professional competence and two aspects of student teachers’ engagement with the theory-practice link. The qualitative findings offered an in-depth understanding of the ways in which student teachers connected theoretical knowledge learned in ITE coursework and practical experience in ITE fieldwork in developing their professional competence: (1) theoretical knowledge as a guide for professional decisions and a tool for reflection on practice; (2) practicalizing theoretical knowledge: adapting theoretical knowledge to practice situations. In the process of engagement, theoretical knowledge was transformed and adapted to practice situations when student teachers coped with the challenges of the teaching contexts in their ITE fieldwork. While affirming the value of student teachers’ engagement with the theory-practice link, the findings of the study shed light on ITE practices for preparing student teachers for such engagement.  相似文献

This study focuses on exploring teacher learning in terms of teachers’ professional agency embedded in the classroom. Teachers’ sense of professional agency is related to perceiving instruction as a bidirectional process, use of students as a resource for professional learning and continuous reflection on teaching practices. Accordingly, the capacity to cross the boundaries in teacher learning contributes active professional agency and, consequently to work-related well-being. Hence, the interrelations between teachers’ sense of professional agency and the burnout they experienced were also analysed. Altogether 2310 Finnish comprehensive school teachers, including primary, subject and special education teachers, completed the study survey. The results indicated that active professional agency, promoting both learning and well-being, requires not just reflecting and adapting but also efforts to learn at work. Moreover this requires not just self-directed and active professional practice but also learning at the boundaries and creating new professional knowledge together with students and colleagues.  相似文献

In this case study, the professional mathematics teacher identity (PMTI) of final year mathematics education students is investigated in terms of their self-perceived and actualised identity. These prospective teachers were required to discuss and describe their own PMTI in terms of three aspects: mathematics specialisation, teaching-and-learning specialisation, and caring. Subsequently, they were observed in the classroom, where the actualisation of their PMTI was considered in terms of the same three. The participants’ perceptions of their own PMTI and the actualisation of that PMTI in the classroom were found not to be congruent. While their self-perceptions regarding their prowess as Mathematics Specialists were accurate, since this is concretely tested as part of their studies, their self-perceptions as teaching-and-learning specialists and particularly as Carers, were not verifiable in their classroom practice. Espoused theory, theory that the individual perceives as true and valid, and which may thus be seen as intrinsic to their PMTI’s, is not necessarily enacted.  相似文献

A random sample of primary grade teachers from across the United States was surveyed about their instructional practices in handwriting. Nine out of every ten teachers indicated that they taught handwriting, averaging 70 minutes of instruction per week. Only 12% of teachers, however, indicated that the education courses taken in college adequately prepared them to teach handwriting. Despite this lack of formal preparation, the majority of teachers used a variety of recommended instructional practices for teaching handwriting. The application of such practices, though, was applied unevenly, raising concerns about the quality of handwriting instruction for all children. Preparation of this paper was supported by the Center to Accelerate Student Learning, funded by the U.S. Department of Education’s Office of Special Education Programs Grant H324V980001.  相似文献

This paper reviews the characteristics of students entering initial training in four countries—Ghana, Lesotho, Malawi, and Trinidad and Tobago. First a brief overview of the teacher education systems is provided. Second, biographical data is reviewed on age, religious affiliation, ethnic group and mother tongue, parental occupations and academic achievement, and students’ educational qualifications. Third, some insights into trainees’ perceptions about teaching and the teaching profession are presented. Finally, comparisons are made for two countries on cross-sectional data comparing the perceptions of entering and exiting trainees and newly qualified teachers. The results draw attention to the qualities and perceptions that those on initial training programmes bring to the teacher education curriculum. They provide a reminder that teacher education curricula should recognise these characteristics and be designed to respond to needs that they create.  相似文献

Implicit bias, unconscious beliefs based upon stereotypes and prejudices, has emerged as a useful way to understand and explain issues of discrimination, particularly involving race. The influence of implicit bias has been explored in various academic disciplines and numerous contexts, including education. Despite the burgeoning research literature, there is limited research on the role implicit bias plays within the classroom. The goal of this special issue is to broaden and challenge the current thinking on teacher implicit bias and attitudes as well as their influence on students.  相似文献

Teachers’ current uses of technologies still tend to replicate traditional and/ or administrative practices, with research indicating that the pedagogies required for the effective integration of educational technologies are not yet in evidence amongst the majority of teachers. In order to conceptualise what could be considered effective pedagogies for the use of technology, greater understanding of what informs teachers’ particular approaches and how teachers come to change their approaches over time is required. Succinctly, what is needed is a deep understanding of a teacher’s developmental process for their conceptualisation of the relationship between technology and pedagogy. Through an in-depth, two-year case study methodology, three teachers’ journey to use game-based technologies in their classrooms was examined. The results provide valuable insights into the relationship between teachers’ pedagogical beliefs and practices about the use of technologies; trigger points in teachers’ journeys that influence change in their pedagogical orientation for the use of technology; and rich stories of innovation in teaching. This study has implications for teacher professional development and supporting effective technology integration.  相似文献

There is a need to hear the voices of student teachers as they grapple with the dilemmas during theor school experience brought about by their dual role as students and teachers. In this paper, the story of Roger is told and the issues raised in his story are highlighted through the contrast provided by a briefer presentation of Diane's story. The concept of personal practical knowledge and images of teaching are used to explore the perspectives of these two student teachers. The discussion focuses on differences in the dialogue in which each of the student teachers is involved. Suggestions are made that the dialogue during practice teaching should focus on self-awareness, that the process should be one of negotiation and re-construction and that a collaborative experience should be the primary aim.  相似文献

In this paper, we present preliminary findings from a unique collaborative research project involving six Deaf Māori rangatahi (youth) in Tāmaki Makaurau (Auckland), Aotearoa New Zealand. This study utilized kaupapa whānau (research family) protocols, established in consultation with two cultural advisory groups within New Zealand and the young people themselves, combined with elements of photovoice methodology, to explore the identities of these youth. Emerging findings highlight the complex nature of these youth’s cultural identity as well as specific issues related to access to and participation within te ao Māori (the Māori world). Specific and critical reflections on the research process are also included.  相似文献
