Various educational technologies have been advanced as potential vehicles to transform teaching and learning. Still, research studies have documented that primary school teachers struggle to integrate technology in meaningful ways. This article presents the findings of a year-long study in which the author frequently observed three primary school teachers’ enactments of technology into their mathematics teaching. Each teacher was observed between 25 and 30 times during the school year. The types of technologies used as well as the types of mathematical tasks and problems that participants posed while teaching with technology were inductively analyzed. Inductive qualitative analyses indicated that participants’ technology use focused on presentation technologies such as the document camera or interactive whiteboard more than computer-based technologies or interactive activities. Further, teachers varied widely in their enacted pedagogies while integrating technology, and two participants demonstrated more frequent enactments of learner-centered pedagogies toward the end of the school year. Implications for researching teachers’ use of technology in the future are also shared. 相似文献

Over the last two decades, state education agencies (SEAs) have been given considerable responsibilities for improving low-performing schools and for adopting research-based practices in doing so. Yet we know little about how and where these organizations search for, select, and use research and other kinds of evidence. We examined these questions as they relate to school improvement designs and strategies in three SEAs using a combination of surveys and interviews conducted in 2010–11. We found that SEA staffs relied most heavily on their colleagues for information but that information often flowed across departments and offices, contrary to the usual image of the SEA as a segmented and siloed bureaucracy. A large number of external organizations were identified in SEA research advice networks and played a catalyzing role in the design or elaboration of research for policy. Although most sources were named by just one person, each SEA also had central internal staff who played an important role in brokering research on school improvement. Identifying and cultivating such influential actors, and connecting individuals who are now isolated or only weakly engaged in these communication networks, could create a more robust exchange of knowledge around school improvement. 相似文献

Using data from the Early Childhood Longitudinal Study (ECLS) 1998/1999, we examine the relationship between elementary students’ (K–5) manipulative use and mathematics learning. Using a cross-sectional correlational analysis, we found no relationship between manipulative use and student mathematics achievement. However, using a longitudinal analysis, we documented a positive relationship between manipulative use and student mathematics learning during their elementary school years (K–5). From a teaching and learning perspective, these findings provide important evidence of the influence of long-term manipulative use on students’ overall learning. From policy and methodological perspectives, these findings provide evidence for the importance of modeling student learning (as opposed to achievement) when studying the effectiveness of instructional strategies. 相似文献

This study focussed on how secondary school students construct and use mathematical models as conceptual tools when solving
word problems. The participants were 511 secondary-school students who were in the final year of compulsory education (15–16
years old). Four levels of the development of constructing and using mathematical models were identified using a constant-comparative
methodology to analyse the student’s problem-solving processes. Identifying the general in the particular and using the particular
to endow the general with meaning were the key elements employed by students in the processes of construction and use of models
in the different situations. In addition, attention was paid to the difficulties that students had in using their mathematical
knowledge to solve these situations. Finally, implications are provided for drawing upon student’s use of mathematical models
as conceptual tools to support the development of mathematical competence from socio-cultural perspectives of learning. 相似文献

Mathematics teacher education aims to improve teachers’ use of mathematical knowledge to support teaching and learning, an aspect of pedagogical content knowledge (PCK). In this study, we interviewed teachers to understand how they used mathematics to make sense of student solutions to proportional reasoning problems. The larger purpose was to find accurate ways of categorizing teachers’ ability to do this vital aspect of teaching and thereby to inform assessment, teacher education, and professional development. We conjectured that teachers’ PCK for proportional reasoning could be reliably described in terms of attention to quantitative meanings in story problem contexts and in terms of understanding naïve forms of proportional reasoning. Instead, our findings reveal that individual teachers used a variety of means to make sense of (1) cognitively similar student solutions to different tasks and (2) mathematically related steps of a student solution within a single task. These findings illustrate the complexity of PCK for the topic of proportional reasoning and suggest the limits of what can be inferred about teacher knowledge from teachers’ evaluations of student solutions. We discuss implications for teacher education and assessment. 相似文献

Exploring the Concept of ‘Habitus’ with Preservice Teachers Through the Use of Popular School Films 总被引：1，自引：0，他引：1
James Trier 《Interchange》2002,33(3):237-260
The thesis of this paper is that it is a productive venture to introduce preservice students to social theories that are typically not a part of teacher preparation programs. Examples of these theories are those associated with terms such as habitus, the carnivalesque, power / knowledge, seduction, detournement, the spectacle,la perruque, (the wig), and the art of making do,as well as others. In this paper, I describe a project that involved exploring the theory of habitus to problematize the tendency of preservice students to not think in terms of relations between what goes on in the classroom and what goes on in society. I introduced habitus by having preservice students read selected print materials and by having them view, analyze, and respond in writing to popular school films. Students also analyzed their experiences in classrooms in terms of habitus, making a connection between theory and practice. 相似文献

Seven children were identified by staff consensus as being the most troublesome pupils in a comprehensive secondary school. A study was then conducted to examine the effects of ‘say‐do’ correspondence training in reducing the amount of troublesome behaviour engaged in by these pupils in the classroom. Such behaviour was defined as ‘talking out of turn’ and ‘hindering other children’, behaviours which had already been found to be the most common categories of troublesome behaviour for secondary classroom teachers.
A multiple baseline across subjects design was employed which brought about a reduction in these two behaviours for three girls and three boys. The behaviour of a fourth boy, however, did not improve beyond the first half of the intervention period. This outcome is discussed in terms of a general deterioration in behaviour and competing contingencies in the classroom. There was some evidence of the generalisation of effects across settings and an increase in the amount of homework submitted.
These results build upon existing research which shows that correspondence training is a useful strategy for dealing with some common classroom behaviour problems. This paper reports an extension of the application of the correspondence training procedures to secondary school pupils of both sexes and covers a broad range of academic ability. 相似文献

In the present paper we discuss the merits of a general multilevel approach to model analysis of large scale school effectiveness studies. We briefly review previous research framework which have been used in school effectiveness research and examine critically the assumptions on which they were based and the methodological implications of these assumptions. The general interaction models presented in this paper provide an answer to many of these critiques. Findings from different types of modeling supported the claim that the modeling of school effectiveness studies must be both multilevel and interactive. Achievement is found to be dependent in a very sensitive, non‐additive way, on the particular combination of pupil's home background, his or her general ability, teaching style and other teacher characteristics, the class and the school context in which the pupil learns. Comparisons between parsimonious main effect models with parsimonious interactive ones show that although the explanatory power of interaction models might be slightly smaller, the use of interaction models causes changes in the specification of the models that cannot be ignored. 相似文献

Cyberbullying and threats of Internet predators, not to mention the enduring consequences of postings, may lead to dangerous, unspeakable consequences. Cyberbullying and threats of Internet predators through social networking sites and instant messaging programs are initiating numerous problems for parents, school administrators, and law enforcement on a national level (McKenna 2007, 60). A 34 item survey was developed to assess Knowledge of appropriate behavior on social networking sites (alpha = .84), Bullying Behavior (alpha = .72), and Internet Use (alpha = .78) of social networking sites for N = 588 grade 7–8 students from an urban and a suburban school. Implications for educators and parents regarding Cyberbullying and Internet Predators are discussed. 相似文献

My grandfather was a teacher. He was the headteacher of a school for boys between the ages of thirteen and eighteen. I know that he was a kind and gentle man at heart, because when I was young(and he was old), he gave me presents, and sat me on his knee, and told me stories. But I believe the boys at his school were afraid of him. 相似文献

Advertisements must bring a certain product to the attention of potential buyers. Further, they must stress its qualities in the most attractive way clearly outline the reason for buying it, and leave a memorable echo of what has been said ringing in the reader's or listener's mind. Therefore, the wording of an advertisement must have immediate impact and rapid persuasion. 相似文献
