Learning to pose mathematical tasks is one of the challenges of learning to teach mathematics. How and when preservice teachers may learn this essential practice,however, is not at all clear. This paper reports on a study that examined the changes in the problem posing strategies of a group of elementary preservice teachers as they posed problems to pupils. It reports that their later problem posing practices significantly differed from their earlier ones. Rather than posing traditional single steps and computational problems, these preservice teachers ventured into posing problems that had multiple approaches and solutions, were open-ended and exploratory, and were cognitively more complex. Their problem posing style also changed. Rather than making adaptations that made students' work easier or narrowed the mathematical scope of the problem, their adaptations became less leading and less focused on avoiding pupils' errors. Posing problems to an authentic audience, engaging in collaborative posing, and having access and opportunities to explore new kinds of problems are highlighted as important factors in promoting and supporting the reported changes. This revised version was published online in August 2006 with corrections to the Cover Date.  相似文献

School students of all ages, including those who subsequently become teachers, have limited experience posing their own mathematical problems. Yet problem posing, both as an act of mathematical inquiry and of mathematics teaching, is part of the mathematics education reform vision that seeks to promote mathematics as an worthy intellectual activity. In this study, the authors explored the problem-posing behavior of elementary prospective teachers, which entailed analyzing the kinds of problems they posed as a result of two interventions. The interventions were designed to probe the effects of (a) exploration of a mathematical situation as a precursor to mathematical problem posing, and (b) development of aesthetic criteria to judge the mathematical quality of the problems posed. Results show that both interventions led to improved problem posing and mathematically richer understandings of what makes a problem ‘good.’  相似文献

Over the past three decades, research and policy in many geographic regions has promoted a shift from direct, lecture-oriented mathematics instruction to inquiry-based, dialogic forms of instruction. While theory and research support dialogic instructional approaches, some have noted that the complexities of dialogic teaching make it difficult for teachers to implement. One mechanism by which teachers can improve their decision-making practices in dialogic classrooms is learning to notice (i.e. becoming aware of learners’ processes). While research has contributed frameworks for understanding how teachers notice individual learners’ mathematical thinking, there is little conceptualization regarding how teachers notice group processes in mathematics classrooms, which is integral to dialogic instruction. We offer a noticing framework termed professional noticing of coordinated mathematical thinking that describes how teachers notice group activity in mathematics classrooms. Professional noticing of coordinated mathematical thinking is conceptualized as a bi-dimensional process: noticing groups’ mathematical activity and noticing groups’ coordinated activity. Teachers must become aware of how groups approach the mathematical and collaborative nature of a task, since both of these aspects inform whether learners develop opportunities to learn in groups. The framework describes noticing practices integral to dialogic instruction and promotes inquiry for future research related to teaching moves in dialogic classrooms.  相似文献

ABSTRACT

Playlinks, the project documented in this paper, contributed a theatre-based artist-in-the-classroom study to the Community Arts Zone initiative. Playlinks involved 248 elementary school classrooms in pre- and post-production workshops connected to live theatre that visited their schools. Data sources included researcher field notes, teacher evaluation forms, and interviews with both teachers and theatre personnel. Findings focus on teacher perceptions of three topics: (a) student engagement, (b) learning across cognitive and affective domains, and (c) benefits for teachers. The discussion section addresses implementation problems related to artist-in-the-classroom projects.  相似文献

This paper reports a study about how a teacher educator shared knowledge with teachers when they worked together to implement mathematical problem posing (MPP) in the classroom. It includes feasible methods for getting practitioners to use research-based tasks aligned to the curriculum in order to encourage children to pose mathematical problems. Techniques, challenges, and strategies of implementing an MPP focus were also reported.  相似文献

The present study explored whether first and second order cognitive holding power perceived by children in mathematical classrooms, fluid intelligence, and mathematical achievement predicted their performance on standard problems, and especially realistic problems. A sample of 119 Chinese 4–6th graders were administered the word problem test, the cognitive holding power questionnaire, and Raven's standard progressive matrices. Results showed that: (1) children's fluid intelligence and general mathematical achievement significantly predicted their performance on both realistic and standard problems, however, second order cognitive holding power predicted their performance on realistic problems but not standard problems; (2) the relationship between first order cognitive holding power and children's correct answers to realistic problems was mediated by second order cognitive holding power; (3) children's performance on standard problems was significantly better than that on realistic problems, and children's performance on both types of problems improved with their grades.  相似文献

This study investigated the effectiveness of an instructional program (schema-based instruction, SBI) designed to teach 7th graders how to comprehend and solve proportion problems involving ratios/rates, scale drawings, and percents. The SBI program emphasized the underlying mathematical structure of problems via schematic diagrams, focused on a 4-step procedure to support and monitor problem solving, and addressed the flexible use of alternative solution strategies based on the problem situation. Blocking by teacher at three middle schools, the authors randomly assigned the 21 classrooms to one of two conditions: SBI and control. Classroom teachers provided the instruction. Results of multilevel modeling used to test for treatment effects after accounting for pretests and other characteristics (gender, ethnicity) revealed the direct effects of SBI on mathematical problem solving at posttest. However, the improved problem solving skills were not maintained a month later when SBI was no longer in effect nor did the skills transfer to solving problems in new domain-level content.  相似文献

Although official curriculum documents make cursory mention of the need for problem posing in school mathematics, problem posing rarely becomes part of the implemented or assessed curriculum. This paper provides examples of how problem posing can be made an integral part of mathematics teacher education programs. It is argued that such programs are a good place to start the process of redesigning mathematics curricula so that school mathematics will pay more than lip service to problem posing. Data are presented and analyzed showing that teacher education students can recognize the need for problem posing both in their own programs and in school mathematics curricula. Examples of problems posed by teacher education students are presented and discussed. An active learning framework for interpreting the role of problem posing in mathematics classrooms is presented.  相似文献

Accumulating evidence indicates handwriting automaticity is related to the development of effective writing skills. The present study examined the levels of handwriting automaticity of Australian children at the end of kindergarten and the amount and type of writing instruction they experienced before entering first grade. The current study involved 177 kindergarten children enrolled in 23 classrooms from seven government-funded primary schools in Western Australia. Individual child level data (e.g., handwriting automaticity and word-reading skills) were collected and teachers were asked to complete a survey assessing the amount of time and types of writing activities developed in their classrooms (e.g., teaching basic skills and teaching writing processes). Hierarchical linear models were conducted to examine total variance attributable to child and classroom levels. Results showed a total variance of approximately 20% in children’s handwriting automaticity attributable to differences among classrooms when gender and word-reading skills were controlled for. Large variability was noted in the amount and type of writing instruction reported by a subset of participating teachers. Handwriting automaticity was associated with the teaching of revising strategies but not with the teaching of handwriting. Implications for writing development and writing instruction are discussed.  相似文献

Despite recent calls for teachers to promote and increase students’ communication and discussion in their classrooms, prospective teachers have limited opportunities to explore issues of classroom talk during their teacher preparation programs. In this study, prospective teachers attending a mathematics methods course were encouraged to attend to and investigate their developing teacherly talk through a letter writing exchange with school students. This paper reports on their tendency to respond to the correct answers with praise and to supply the answers when students reached an incorrect result. It explores the ways in which they began to interrogate and problematize such practices and to consider alternative forms of teacher responses to students’ right and wrong answers. Features of the course's field-related experience and the teacher educators’ interventions that promoted and supported the preservice teachers’ investigations are also discussed.  相似文献

“Success stories,” i.e., cases in which mathematical problems posed in a controlled setting are perceived by the problem posers or other individuals as interesting, cognitively demanding, or surprising, are essential for understanding the nature of problem posing. This paper analyzes two success stories that occurred with individuals of different mathematical backgrounds and experience in the context of a problem-posing task known from past research as the Billiard Task. The analysis focuses on understanding the ways the participants develop their initial ideas into problems they evaluate as interesting ones. Three common traits were inferred from the participants' problem-posing actions, despite individual differences. First, the participants relied on particular sets of prototypical problems, but strived to make new problems not too similar to the prototypes. Second, exploration and problem solving were involved in posing the most interesting problems. Third, the participants' problem posing involved similar stages: warming-up, searching for an interesting mathematical phenomenon, hiding the problem-posing process in the problem's formulation, and reviewing. The paper concludes with remarks about possible implications of the findings for research and practice.  相似文献

This paper explores the nature of prospective teachers’ noticing of students’ understanding as they analyze and discuss middle school students’ understandings of trapezoids in micro-case videos in the context of geometry. In this exploratory study, the data were obtained from eight prospective middle school mathematics teachers through individual video analysis, reflection papers, and group discussions. The results indicated that the use of purposeful micro-case video designs based on prospective teachers’ background knowledge of quadrilaterals allowed them to be productive in video analyses and discussions. In individual video analyses, prospective teachers attended to various mathematical elements to identify students’ responses but did not always use them to make interpretations of each student’s understanding of trapezoid. In the group discussions of the micro-case videos, in contrast, prospective teachers could provide alternative interpretations of students’ understanding by identifying links between the mathematical elements in students’ responses and the characteristics of students’ understandings. In the group discussions, they provided more detailed and specific instructional actions to support each student’s understanding of trapezoid than their individual video analyses. This study suggests practical implications for teacher education programs on how to use video cases (e.g., firstly, working individually and then having group discussions about the videos) to explore prospective teachers’ professional noticing skills. Considering prospective teachers’ background knowledge of related mathematical contents, this study can also inspire future studies on how to design effective videos about students’ mathematical understanding.

This study examined the development of beginning writing skills in kindergarten and the relationship between early writing skills and early reading skills. Sixty children were assessed on beginning writing skills (including letter writing, individual sound spelling, and real and nonsense word spelling) and beginning reading skills (including letter name and letter sound knowledge, global early reading ability, phonological awareness, and word reading). Children’s beginning writing abilities are described, and they exhibited a range of proficiency in their ability to write letters, spell sounds, and spell real and nonsense words. Global early reading proficiency, phonological awareness, and/or letter sound fluency predicted letter writing, sound spelling, and spelling of real and nonsense words. Appreciation is expressed to the participating students and teachers at Dwight D. Eisenhower School and to Margaret Boudreau and Joan Foley for assistance in scoring students’ responses.  相似文献

Abstract

This article considers how teachers working across three countries can create a collaborative writing environment in their classrooms. It reports on the first phase of a research programme conducted by university lecturers in the United Kingdom, Australia and Canada, investigating ways of developing teachers' expertise in the linking of information technology (IT) and pedagogy. It examines writing practices in the secondary classroom, in particular focusing on collaborative writing, and explores how this can be extended and developed through the use of IT. The research operates at three levels of collaboration: first, between the researchers involved; secondly, between teachers sharing their pedagogical expertise; and thirdly, between school students engaging in writing across the limits usually imposed by time and space. A fundamental hypothesis is that experienced and capable teachers of writing in different countries can extend their pedagogical skills through working together. Such collaboration between both teachers and school students has only recently become a possibility as a result of wider access to the Internet and the World Wide Web, on which it is eventually intended to publish results of the research, including examples of student work.  相似文献

This paper describes the implementation of extended analysis tasks (EATs) in a required mathematics course for prospective high school mathematics teachers, and investigates the mathematical discovery promoted through engagement with these tasks. Extended analysis tasks are designed to move students beyond the problem context to the underlying mathematical structure of the problem. The results of this study revealed that with careful implementation, these tasks were effective for generating powerful mathematical thinking in preservice mathematics teachers, improving their problem solving, and generally enhancing the habits-of-mind exhibited by successful mathematicians (Carlson & Bloom, 2005).  相似文献

In the present study, which is a part of a research project about realistic word problem solving and problem posing in Chinese elementary schools, a problem solving and a problem posing test were administered to 128 pre-service and in-service elementary school teachers from Tianjin City in China, wherein the teachers were asked to solve 3 contextually challenging division-with-remainder (DWR) word problems and pose word problems according to 3 symbolic expressions. Afterwards, they were also given 2 questionnaires wherein they had to evaluate 3 different pupil reactions to, respectively, 1 problem solving item and 1 problem posing item about DWR. First, our results revealed that teachers behaved quite ‘realistically’ not only when solving and posing DWR problems themselves but also when evaluating elementary school pupils’ DWR problem solving and problem posing performance. Second, we found a correspondence between teachers’ own performance on the tests and their evaluations of pupils’ reactions. Third, the present study provides some further insight into the role of one of the instructional factors that is generally considered responsible for the strong and worldwide tendency among elementary school children to neglect real-world knowledge and realistic considerations in their endeavours to solve and pose mathematical word problems, namely the teachers’ conceptions and beliefs about this topic.  相似文献
