Generalization of patterns: the tension between algebraic thinking and algebraic notation 总被引：2，自引：0，他引：2
This study explores the attempts of a group of preservice elementary school teachers to generalize a repeating visual number pattern. We discuss students' emergent algebraic thinking and the variety of ways in which they generalize and symbolize their generalizations. Our results indicate that students' ability to express generality verbally was not accompanied by, and did not depend on, algebraic notation. However, participants often perceived their complete and accurate solutions that did not involve algebraic symbolism as inadequate.This revised version was published online in September 2005 with corrections to the Cover Date. 相似文献

This article discusses the relation and patterns of intra- and inter-group discourse as middle school students explain particular
phenomena. We present a framework of the dynamic process involved in generating collaborative knowledge. Our focus is on connecting
students' thinking and experience with science concepts and explanations. Using the perspective of learning as a social activity,
we are interested in science teaching that engages students in collaborative inquiry as a means for learning science content.
Specifically, we examine the role of shared inquiry and the nature of consensus-building in students' development of explanations
from a collaborative knowledge-building stance. Student discourse, in small (intra-group) and large (inter-group) contexts,
is examined as an explicit mode of inquiry. While additional study is needed, we contend these two forms of discourse (constructive
and generative; dialectic and persuasive) effectively promote progressive discourse and thereby facilitate shared coherent
explanations of phenomena.
If we now consider dialectics rather than method as the logic of science, the whole image changes because of the essential,
constitutive role played by interlocutors. Due to this role, science becomes a game with three players: an inquiring mind,
or, more realistically, a group of the communityC

This paper describes responses from 28 first-year university physics students to one question of a written test which was
followed up by an interview. The study has two main research aims. Firstly, it characterises the conceptual structures of
students regarding the phenomenon in question. As well as being interesting in their own right, these student understandings
cast light on some broader issues regarding understanding of field representations. While students' understandings of circuit
electricity are well described in the existing science education literature, their understandings of field phenomena are not.
Secondly, it throws light on theoretical questions about the SOLO Taxonomy, which is the framework used to study the students'
conceptual structures. Of particular interest is the nature of student thinking that marks transition from the Concrete Symbolic
to the Formal SOLO mode in this area.

Socialization of Doctoral Students to Academic Norms 总被引：1，自引：0，他引：1
Using the framework for graduate and professional student socialization developed by Weidman, Twale, and Stein (2001), this study addresses socialization of doctoral students to the academic norms of research and scholarship. Data are presented about the perceptions doctoral students in a social science discipline (sociology) and in educational foundations at a major research university have of the scholarly and collegial climates of their departments. Data on students' social relationships with faculty and peers as well as their reported participation in scholarly activities are also reported. A multivariate analysis provides support for the framework, affirming the importance of social interaction among both students and faculty as well as collegiality among faculty for creating a supportive climate for doctoral study that also has the potential to provide a strong foundation for subsequent academic and/or research careers by stimulating students' research and scholarly productivity. 相似文献

This article reports on a study conducted in a graduate teacher research class with elementary and secondary classroom teachers. Wanting to create a collaborative environment in which their students could use language to support each other's learning, the instructors formed discourse groups. The article introduces a theoretical framework for discourse groups and using examples from the groups, presents a methodology for analyzing the social practices reflected in the teachers’ talk. It concludes with a discussion of the nature of the discourse that supported (and in some cases did not support) the re-storying of teachers’ knowledge. 相似文献

Proof and reasoning are fundamental aspects of mathematics. Yet, how to help students develop the skills they need to engage
in this type of higher-order thinking remains elusive. In order to contribute to the dialogue on this subject, we share results
from a classroom-based interpretive study of teaching and learning proof in geometry. The goal of this research was to identify
factors that may be related to the development of proof understanding. In this paper, we identify and interpret students'
actions, teacher's actions, and social aspects that are evident in a classroom in which students discuss mathematical conjectures,
justification processes and student-generated proofs. We conclude that pedagogical choices made by the teacher, as manifested
in the teacher's actions, are key to the type of classroom environment that is established and, hence, to students' opportunities
to hone their proof and reasoning skills. More specifically, the teacher's choice to pose open-ended tasks (tasks which are
not limited to one specific solution or solution strategy), engage in dialogue that places responsibility for reasoning on
the students, analyze student arguments, and coach students as they reason, creates an environment in which participating
students make conjectures, provide justifications, and build chains of reasoning. In this environment, students who actively
participate in the classroom discourse are supported as they engage in proof development activities. By examining connections
between teacher and student actions within a social context, we offer a first step in linking teachers' practice to students'
understanding of proof. 相似文献

Our overall intent is to clarify relations between the psychological constructivist, sociocultural, and emergent perspectives. We provide a grounding for the comparisons in the first part of the article by outlining an interpretive framework that we developed in the course of a classroom-based research project. At this level of classroom processes, the framework involves an emergent approach in which psychological constructivist analyses of individual activity are coordinated with interactionist analyses of classroom interactions and discourse. In the second part of the article, we describe an elaboration of the framework that locates classroom processes in school and societal contexts. The perspective taken at this level is broadly sociocultural and focuses on the influence of indlividuals' participation in culturally organized practices. In the third part of the article, we use the discussion of the framework as a backdrop against which to compare and contrast the three theoretical perspectives. We discuss how the emergent approach augments the psychological constructivist perspective by making it possible to locate analyses of individual students' constructive activities in social context. In addition, we consider the purposes for which the emergent and sociocultural perspectives might be particularly appropriate and observe that they together offer characterizations of individual students' activities, the classroom community, and broader communities of practice. 相似文献

Interactions between peers as well as between students and teachers play an important role in social learning. Although much research investigates the structure of (peer) discourse and its relation to learning outcomes, only a few studies try to describe in detail how individuals create meaning for content developed within the dialogues. Thus, it often remains unclear which contents and structures of the discourse contributed to the development of individual knowledge and which did not. This paper describes a study that investigated in great detail peer discourse and its relation to the cognitive development of every participating learner. In total, 27 university students were followed with video while working in pairs during physics laboratory exercises on electrodynamics. Students' cognitive processes developed during their interactions were reconstructed from the video by a small step analysis and students' meaning-making of other participants' contributions was investigated. Results show that students only interact about topics they already know whereas they develop new meaning outside of interactive processes. 相似文献

Background: Teenagers need information about their changing bodies. Many young people do not receive adequate or accurate puberty/sexuality education from their parents or school, so many teenagers are going online to have their sexuality questions answered. Purpose: This research examines teenagers’ web questions on sexuality, and an example of the puberty and sexuality education content that some may learn in school. It looks for evidence of heteronormative conceptualisations of gender and sexuality, using a theoretical framework based on the Four Discourses of Sexuality Education. Sample: This includes the web questions (n = 200) of an evenly gendered sample of 13–15‐year-old students (n = 180) from four English-speaking nations, namely UK, USA, Canada and Australia, selected from a reputable puberty/sexuality education site, and, for comparison, an example of an age-representative public school Health and Physical Education (HPE) puberty/sexuality education curriculum. Method: A gendered and narrative-thematic Content Analysis was undertaken, using the Four Discourses theoretical framework, on the students’ sexuality web questions, and also on the school HPE curriculum. Results: The discourse of Victimisation was evident in nearly half of all students’ web questions, and over a third of the HPE curriculum. The discourse of Individual Morality was present in a quarter of both students’ questions and the curriculum, while the discourse of Desire was evidenced in a fifth of students’ questions and almost a third of curriculum content. Somewhat surprisingly, the discourse of Violence was present in 9% of exclusively female students’ web questions, and in 12% of the curriculum. Conclusion: It is recommended that the sampled HPE curriculum, and similar curricula in these sampled students’ countries, need explicitly to address gender differences in students’ metacognition and conceptualisations of puberty and sexuality. This may enable students to embrace their entitlement to sexual subjectivity, in education and across the lifespan, thus helping to ensure students’ healthy, positive and purposeful life outcomes. 相似文献

This research investigated the emergent discursive modes and their pedagogical functions found in model-based inquiry (MBI) science classrooms. A sample of four high school physics classrooms was video-recorded and analysed using a newly established discourse mode analysis framework. Qualitative methods were employed to identify the most salient types and sequences of discursive modes and to interpret their pedagogical functions in the context of MBI. Results indicated that exploring was one of the most frequently used discursive modes in the MBI classrooms. Sometimes two different types of exploring discourse were connected sequentially so that the pattern of exploring (scientific phenomena)–exploring (student ideas) appeared. The discursive sequences of exploring–retrieving and exploring–negotiating also emerged whereby the teacher guided students to align their models with the canonical knowledge of science. The teacher also helped students in modelling using elaborating and reformulating discourse modes as well as metadiscourse. Although the MBI classes were implemented in a manner similar to teacher-guided inquiry, it was also observed that students participated actively in several discursive practices. Implications for model- or modelling-based science instruction and science education research were discussed. 相似文献

Part of the research community that has followed the Early Algebra paradigm is currently delimiting the differences between arithmetic thinking and algebraic thinking. This trend could prevent new research approaches to the problem of learning algebra, hiding the importance of considering an arithmetico–algebraic thinking, a new approach which underpins the construction of a cognitive structure that links both types of thinking. This paper proposes a theoretical and practical framework for a learning approach that supports the construction of a cognitive structure which fosters arithmetico-algebraic thinking at the beginning of secondary school by means of cultural and technological activities relating to polygonal numbers. 相似文献

Counselling for work and relationship is proposed as another way of thinking about vocational psychology and vocational guidance. It can contribute to the search for a new paradigm for these fields. Central to this way of thinking are two shifts. A shift from a discourse about career to a discourse about work, and a shift to expand the focus of attention beyond the occupational domain to include multiple social contexts of work and relationship across both occupational and personal domains of life. The ways in which these shifts are responsive to theoretical and social contexts is considered. 相似文献

Previous research about college students’ social media usage emphasizes social media practices, often ignoring the content that students’ post. Increasing knowledge about the language that college students use to describe their intimate relationships can inform student affairs practice. Using a digital ethnographic data collection approach and queer theoretical framework, this paper explores the dominant discourses about race, sexuality, and relationships circulated in a mobile social networking application. This paper used content analysis to describe the meaning of text and images produced by college-aged youth in the US. Through this analysis of social media content, I contend that college students engage in the complex representations and reproductions of sociocultural norms about bodies, sexuality, and relationships and that these representations and reproductions influence campus climate. I develop implications for student affairs administrators. 相似文献

Educational institutions are required to find new pedagogical and cognitive models and practices to cope with the challenges
of an emerging knowledge society. In creating a theoretical and practical model for future education, Scardamalia and Bereiter
have proposed the concept of knowledge building. An early implementation of this idea was in the networked classroom software
and ancillary structures known as Computer-Supported Intentional Learning Environment (CSILE). The present study aimed to
explore the indicators of knowledge building in computer-mediated discourse among 26 11-year-old Finnish students. The data
were collected during a four-week course on Energy, and consisted of students' postings stored in the CSILE database. Analysis
revealed three pedagogically and cognitively different modes of discourse: social-oriented, fact-oriented, and explanation-oriented.
These modes differed essentially from each other in the nature of the knowledge which students constructed during discourse
and in the object and focus of students' communication. During explanation-oriented discourse, students actively used abstract
and scientific concepts and the objects of their comments were theories, ideas and methods of research. Such activity is a
component of knowledge building.

职业教育课程的学科话语与实践话语 总被引：10，自引：0，他引：10
Xu Guoqing associate professor doctorate at the Institute of Vocational Adult Education of Educational College East China Normal University 《教育研究》2007,(1)
20世纪90年代以来,我国职业教育课程的学科话语与实践话语的争论经历了从“数量”到“逻辑”两个阶段。尽管在学术领域实践话语占据了主导,在实践领域却是学科话语占据着主体。目前,我国职业教育课程正处于从传统的以学科课程为主体的课程模式,转向以项目课程或任务引领型课程为主体的课程模式阶段。职业教育课程从学科话语到实践话语的转换,实际上意味着思考课程问题的思维方式的转换。职业教育课程设计应当充分考虑学生的学习特点,打破从理论到实践的机械课程设计思路,转向让学生在工作实践的基础上,通过自我反思来建构理论知识。 相似文献

The zones framework conceived for the examination of thinking about teaching, is validated, and extended to the examination of thinking about learning. This is done by extending the framework to examine thinking about teaching and learning in a population of science graduate student teaching assistants. Semi‐structured interviews explore these students’ teaching and learning experiences, how their experiences relate to their knowledge of educational theory, and how they have formed their ideas about what constitutes good teaching. The article demonstrates that the zones framework can be extended to thinking about learning, and that it is appropriate for examining the thinking of students as well as teachers. Recommendations for further research are made, including the exploration of discipline‐specific thinking. 相似文献

This article reports on classroom research designed to answer questions about authority—how institutions and disciplines, broadly conceived, influence teachers' ability to abnegate authority and how students' experiences influence their perceptions of authority in a business writing and a first-year composition class. The theoretical framework is derived from research about institutional and disciplinary influences on these two areas of study. This framework and our results lead us to speculate about the ways in which our students' experience of the institution and expectations of the classes and their intentions for using the material taught in the classes may have thwarted our attempt to share authority in our classrooms. 相似文献
