This paper synthesizes key findings to facilitate the translation of research into classroom practice and provides guidelines for how effective instructional practices might be implemented, supported, and sustained in schools. Excerpts from a case study are presented to show how research‐based instructional approach translates into classroom practices in a local school district that tailors the approach to the realities of the local situation. In this paper, we review what the research suggests are the functions that allow a person in a leadership role to facilitate the translation of research into classroom practice. We describe how these functions were used to translate research into classroom practice in 2 school districts that are part of the Elementary and Middle School Technical Assistance Center (EMSTAC) project, a national research‐to‐practice effort. Examples of how these principles were put into practice and why different technical assistance approaches were used to implement research‐based practices in a primary and middle school setting are discussed. We conclude with reflections on the intricate nature of effecting change at the local level, and the progress that can be made within those intricacies.  相似文献

As a field, we have a limited understanding and a dearth of empirical research concerning the role of high school instructional coaches focused on English learners (ELs). This paper examines one EL facilitator’s work as an instructional coach and resource for supporting mainstream content teachers as they learn to meet the needs of adolescent ELs in one high school. This analysis is grounded within an examination of the influence of school structure and organization on the EL facilitator’s work and her role as a resource. Drawing on sociocultural learning theory, as well as literature on teacher leadership and instructional coaching, case study data from a year-long qualitative research project are analyzed. Implications for research, policy, and practice are discussed.  相似文献

This paper explores the experiences and perceptions of a little-known category of in-service trainee teachers in the Further Education (FE) and Skills sector in England: those who meet the practical teaching requirements of their course mainly through unpaid teaching as ‘volunteers’. The paper reports findings from mixed-methods research which used surveys, interviews and focus groups involving trainee teachers within a large FE–HE partnership. Themes relating to motivations to volunteer, the development of teacher identity within marginal roles, and the risks associated with unpaid teaching are discussed. For increasing numbers of trainees, unpaid teaching provides an opportunity for career entry. However, the quality of teaching experience gained is mixed, with some trainees receiving high levels of support, whilst others experience marginalisation and limitations on their developing teacher identities. The paper highlights the specific challenges to professionalism posed by unpaid teaching within the FE and Skills sector, and relates these challenges to a broader context of insecurity and risk. As work experience becomes an increasingly valuable commodity, this paper illustrates the pressures individuals face as they exchange payment and security for the opportunities volunteering provides.  相似文献

The rodents, especially voles, evolved very rapidly during the Quaternary era. Their remains, particularly the teeth, were fossilised by the thousand in prehistoric deposits. The sites can be dated from the degree of evolution attained by the teeth. Since rodents are closely adapted to their biotopes and live under well defined climatic conditions, they are extremely valuable for reconstructing the landscapes and climates of prehistory. In many cases, a single rodent tooth can be used to assess the age of a human skull or a prehistoric settlement, and throw light on the environment and climate of the time.  相似文献

The transport of thermal energy in thermodynamics is described as the product of entropy flow and of the absolute temperature, in analogy to the volume flow and pressure in oil hydraulics and to electric charge flow (= current) and voltage in electronics. Bond graphs are shown to be especially suitable to describe the splitting of applied thermal energy into internal energy and external mechanical work. Transformers and the 0- and 1-junctions of Paynter can illustrate various entropy flow processes, including Carnot engines and heat exchangers. Entropy flow in heat conduction is distinguished from entropy convection, or transport by moving mass, where the entropy/temperature characteristic or equation of state is important. Irreversibilities are represented by impedance transformers reducing temperature and increasing entropy flow but conserving power.  相似文献

Information‐rich environments are created to promote data use in schools for the purpose of self‐evaluation and quality assurance. However, providing feedback does not guarantee that schools will actually put it to use. One of the main stumbling blocks relates to the interpretation and diagnosis of the information. This study examines the relationship between data literacy competences, support given in interpreting the information, actual use of the feedback and potential school improvement effect. A randomised field experiment with 188 school principals from primary education was set up and a post‐test was used to investigate the effects of a support initiative. The results revealed that a minority of schools invested significantly in the interpretation and diagnosis of the school performance feedback (SPF), despite the fact that most of the respondents showed an interest in the SPF report. In addition, data competence support and the subsequent use of feedback were found to be limited.  相似文献
