This study offers a view on students’ technology-based problem solving activity through the lens of a theoretical model which accounts for the relationship between mathematical and technological knowledge in successful problem solving. This study takes a qualitative approach building on the work of a 13-year-old girl as an exemplary case of the nature of young students’ spontaneous mathematical problem solving with technology. The empirical data comprise digital records of her approaches to two problems from a web-based mathematical competition where she resorted to GeoGebra and an interview where she explains and describes her usual problem solving activity with this tool. Based on a proposed model for describing the processes of mathematical problem solving with technologies (MPST), the main results show that this student’s solving and expressing the solution are held from the early and continuing interplay between mathematical skills and the perception of the affordances of the tool. The analytical model offers a clear picture of the type of actions that lead to the solution of each problem, revealing the student’s ability to deal with mathematics and technology in problem solving. By acknowledging this as a case of a human-with-media in solving mathematical problems, the students’ efficient way of merging technological and mathematical knowledge is portrayed in terms of her techno-mathematical fluency. 相似文献

This teacher development study closely examined a teacher's practice for the purpose of understanding how she selected and implemented instructional materials, and correspondingly how these processes changed as she developed her problem‐based practice throughout a school year. Data sources included over 20 hours of planning and analysis meetings with the teacher and 27 video‐taped lessons with discussions before and after each lesson. Through qualitative analysis we examined the data for: students' cognitive demand for curricular materials the teacher selected and implemented; teacher's beliefs and practices for students' engagement in mathematical thinking; and teacher's and students' communication about mathematics during instruction. We found that the teacher shifted her views and use of instructional materials as she changed her practice towards more problem‐based approaches. The teacher moved from closely following her traditional, district‐adopted textbook to selecting problem‐based tasks from outside resources to build a curriculum. Simultaneously, she changed her practice to focus more on students' engagement in mathematical thinking and their communication about mathematics as part of learning. During this shift in practice, the teacher began to reify instructional materials, viewing them as instruments of her practice to meet students' needs. The process of shifting her views was gradual over the school year and involved substantial analysis and reflection on practice from the teacher. Implications include that teachers and teacher educators may need to devote more attention and support for teachers to use instructional materials to support instruction, rather than materials to prescribe instruction. This use of instructional materials may be an important part of transforming practice overall. 相似文献

如何界定学科属性与专业内涵、树立学术声誉与专业影响,是教育学院发展的首要难题.哈佛教育研究生院的办学历程显示,由于无法超越大学校长、文理学术界和基金会等外界力量的影响,教育学院只得不断变换教育学的学科界定与专业内涵.教育学院因此而得以发展,其代价却是从未将教育学的学科属性与专业内涵确定下来.不过,只要教育学院在不断完善学科与专业建构的同时,还能在大学、基础教育界乃至社会积累更强大的学术势力,便可以持续推进学科与专业发展,进而争取更好的学术声誉与专业影响. 相似文献

In this paper I explore how women’s thinking subjectivity is structured by a need to negotiate between identifying with and repudiating our mothers. Oriented by Melanie Klein’s theory of matricide which posits that an infant’s capacity to think for herself originates in her need to separate from her mother, I consider the implications of this structure for women’s gendered experiences of intellectualism. To examine how this dilemma of matricide animates women’s thinking lives I read Helen M. Buss’s criticism of Carolyn Kay Steedman’s memoir Landscape for a Good Woman. I argue that Buss’s criticism of Steedman is symptomatic of her ambivalent relation to the problem of identification and repudiation that drives her own intellectual labour. I then turn to a scene in Buss’s memoir, Memoirs from Away, to examine how the matricidal dilemma resonates through her work of reading other women’s memoirs and of writing her own. 相似文献

对当代英国剧坛的先锋作家萨拉·凯恩剧作的研究多关注其中的战争、暴力、性虐和变态人格的极端展示等主题,而其中比较重要的性别问题因其对性别的态度而受到忽视。凯恩三个剧本中的性别关系揭示出她试图在消解性别区分的同时,仍然关注性别问题并以女性的形象来隐喻了人性的救赎和希望。 相似文献

This paper discusses the relationship between arithmetical concepts and solution procedures or methods. A case study is presented to illustrate the contention that some children with relatively sophisticated concepts express those concepts by using primitive methods. The process of distinguishing between these children and those with primitive concepts involves inferring the children's purposes, intentions, and anticipations about the results of their potential problem solving activity. The case study of the child's learning in the context of direct instruction also indicates that her awareness of the limitations of her current methods played a crucial role in her development. The generality of this analysis is then illustrated by drawing analogies from the philosophy of science and mathematics, and from an analysis of the activity of professional practitioners. 相似文献

Abstract This paper describes how a researcher‐lecturer in higher education attempted to identify, in her course, the constraints within which the teaching was required to operate. To better understand this particular problem area in her professional practice, it was necessary to take the student voice seriously and to suggest a possible solution to the problem. It appeared that the ‘Information Technology’ module on a specific postgraduate course was particularly unattractive to the postgraduate students required to take it. The solution proposed was to develop and introduce into the module a form of innovation in course development, namely a Computer Assisted Learning (CAL) tool entitled ‘Interactive Computerised Information Technology Tutor’ (ICITT). The research process leading to the planning, development and introduction of the ICITT is the initial focus of this paper. The ICITT itself is then described in some detail in the latter part of the work. 相似文献

During the interview ‘Mary’ – who had last year been a school pupil and this year is a first‐year undergraduate on the new degree in Education (with Teaching Certificate) – talked at some length, and with considerable feeling, about how her main frustration as a female pupil had been what she saw as her systematic disenfranchisement from influence over the content and process of the schools' curricula which she had pursued over the previous thirteen years. Although she felt that all pupils suffered this lack of influence she was convinced that girls suffered disproportionately. [Some time later in the interview], when talking about the ‘teaching practice’ she had recently completed, ‘Mary’ described how her ‘music and movement’ work had met with ‘loud and disruptive’ reaction from some of the boys in the mixed class of 7–8 year‐olds, even though the majority of the children had clearly enjoyed and been engaged by the scheme she had designed. Faced with this rejection, and experiencing some anxiety about how the teachers and her tutor would assess her potential as a future teacher if she was not seen to be exercising what they would count as ‘good control’ of the class, ‘Mary’ resolved her ‘problem’ by designing an alternative scheme which the few boys would not (and did not) reject. Although the girls had ‘subsequently shown less interest’, their quiet acquiescence to what she offered them reduced her anxiety about her assessment as a teacher. When she related her pupil experience to her teaching practice experience ‘Mary’ was dismayed to realise that she had ‘reproduced for others precisely that frustration which [she herself] had experienced as a pupil’.

冰心是20世纪中国最杰出的文学大师之一。她从1919年五四运动之后,便开始了文学创作。她的作品,如"问题小说"、小诗、散文和儿童文学开创了新文学的先河,而"冰心体"的创造,则是她最杰出的贡献。"爱的哲学"的提出又使她成为现代文学史上最有个性,最有特色的一位女性作家。但是,至今冰心的作品受到评论界充分关注的仍只是她20年代的作品,她三四十年代作品所体现出的一以贯之的对爱与美的追求及其艺术风格,却一直为研究者所忽略,这自然有碍于对冰心创作全貌的把握。本文拟以冰心三四十年代的生活为立足点,试图对她这一阶段的重要作品所表现出的文学精神及艺术风格予以解释。 相似文献

We describe how 1 Algebra I teacher and her 8th-grade students used meta-representational knowledge when generating and evaluating equations to solve word problems. Analyzing data from a sequence of 4 lessons, we found that the teacher and her students used criteria for evaluating equations, in addition to other types of knowledge (e.g., different interpretations of the equal sign) previously reported in the literature. Moreover, the teacher and her students had trouble understanding one another's proposed algebraic models of problem situations due to differences in the criteria that each applied, and this impeded learning. These findings (a) extend an accumulating body of evidence for the role meta-representation plays in mathematics and science learning and (b) add a new dimension to researchers' growing understanding of what teachers must know in order to teach algebra and other complex mathematics and science topics effectively. 相似文献

This paper represents a reflective account of a recent Cambridge University graduate, who critically assesses her successes and struggles in establishing herself as a social science researcher in Western academia. Reflecting on her various (sometimes conflicting and sometimes, in a paradoxical way, complementary) identities, the author explains how her personal oscillation between and dissatisfaction with two systems of thought and patterns of socialization was translated into her research agenda and theoretical/methodological standpoint. Committed to a non-Euro/Americo-centric approach to research, the author views and adopts a poststructuralist perspective as a more powerful explanatory tool, which better accounts for the emerging hybridities, uncertainties, and oscillations that increasingly characterize everything that used to be covered by the term "Soviet": countries, societies, identities, and—of particular relevance to the problematic raised in this paper—intellectuals. The author concludes by problematizing predominant "Western" analytical knowledge traditions, and calling for a new form of political engagement, ethics, and critique as these were once envisaged by Foucault. 相似文献
