Quality Talk and dialogic teaching—an examination of a professional development programme on secondary teachers’ facilitation of student talk          下载免费PDF全文

Maree Davies  Katharina Kiemer  Kane Meissel 《British Educational Research Journal》2017,43(5):968-987

This study used the Quality Talk and dialogic teaching approach with a group of secondary school teachers (N = 7) to train their facilitation of dialogical discussions by small groups of students. The study used video and audio analysis to assess the teachers’ observable behaviours during these discussions, before and after professional development; for example, types of Quality Talk questions asked. The study also used face‐to‐face interviews, held before and after the professional development, to investigate the teachers’ beliefs about learning through discussion. Results show that although the number of high‐quality questions from the teachers did not increase, the quality of the questions students asked of each other did improve, and resulted in extended periods of dialogic spells. Positive developments were found for teachers’ beliefs about the use of dialogue to foster deeper thinking with their secondary school‐aged students.  相似文献   

Rodents,evolution, and prehistory     

Jean Chaline 《Endeavour》1977,1(2):44-51

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   

Bond graphs for thermal energy transport and entropy flow     

Jean U. Thoma 《Journal of The Franklin Institute》1971

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

The power of the ‘object’ to influence teacher induction outcomes     

Glenda Anthony  Mavis Haigh  Ruth Kane   《Teaching and Teacher Education》2011,27(5):861-870

In this paper we explore newly qualified New Zealand secondary teachers’ varied accounts of induction. We claim that multiple interpretations of objectives for induction programs are a significant source of this variation. With reference to an activity system framework, we identify four primary objects of induction that were represented in the induction accounts as follows: ‘orientation to learning about the context’, ‘fitting into the school’, ‘completing registration requirements’, and ‘becoming a professional inquirer’. Whilst teachers would be expected to experience all of these objects within their induction experiences, the balance and emphases of these objects within programs varied considerably.  相似文献   

The influence of competences and support on school performance feedback use     

Jan Vanhoof  Jean Pierre Verhaeghe  Martin Valcke  Peter Van Petegem 《Educational studies》2011,37(2):141-154

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   

Do increased resources increase educational attainment during a period of rising expenditure? Evidence from English secondary schools using a dynamic panel analysis     

Geoff Pugh  Jean Mangan  John Gray 《British Educational Research Journal》2011,37(1):163-189

This article estimates the effects of school expenditure on school performance at Key Stage 4 in England, over the period 2003–07 during which real per pupil expenditure increased rapidly. It adds to previous investigations by using dynamic panel analysis to: exploit time series data on individual schools that only recently has become available; adjust for the potential endogeneity not only of expenditure but also of other determinants of performance; and differentiate the short‐run and the (higher) long‐run attainment effects of spending changes. Consistent with other recent work, the article reports a generally significant but small effect of expenditure on school performance, but it also finds that the effect varies between specialist and non‐specialist schools, with the effect on the latter being larger. Further, the article identifies significant dynamics in the school improvement process, quantifies the long‐run effect of expenditure changes, suggests that spending effects increase with socio‐economic disadvantage, and quantifies absence effects.  相似文献   

A relational vector space model using an advanced weighting scheme for image retrieval     

Jean Martinet  Yves Chiaramella  Philippe Mulhem 《Information processing & management》2011

In this paper, we lay out a relational approach for indexing and retrieving photographs from a collection. The increase of digital image acquisition devices, combined with the growth of the World Wide Web, requires the development of information retrieval (IR) models and systems that provide fast access to images searched by users in databases. The aim of our work is to develop an IR model suited to images, integrating rich semantics for representing this visual data and user queries, which can also be applied to large corpora.  相似文献
