This study sought to understand how dialogic teaching, as enacted in everyday classroom interaction, affords students opportunities for identity negotiation as learners of science. By drawing on sociocultural and sociolinguistic accounts, the study examined how students’ discursive identities were managed and recognized in the moment and over time during dialogic teaching and what consequences these negotiations had for their engagement in science learning. The study used video data of classroom interactions collected from an elementary science learning project and placed a specific analytic focus on four students in particular. The results reveal evidence of a rich variety of discursive identities exposed during dialogic teaching, thus demonstrating how the students’ identity negotiations were configured according to the social architecture of classroom discourse. Addressing the temporal dimension of dialogic teaching points out critical shifts in the students’ discursive identities, of which identification is argued to be pivotal when creating equitable science learning opportunities. 相似文献

Teacher–student discourse continues to be teacher-centred even though researchers and reform documents have recommended changes toward increased levels of student-centred discourse. In science education this situation is paralleled by effort to make scientific inquiry more student-centred. The purpose of this study was to investigate how discourse forms changed over time in a classroom where the regular teacher and his students were scaffolded in the transitioning to student-centred scientific inquiry. Video-recordings were collected at intervals over one academic year. Three prominent forms of discourse were identified: two teacher-authoritative forms and one more interactive, dialogic form. As the lessons increasingly turned into student-centred scientific inquiry, a shift to the dialogic discourse form was found. Co-teaching provided for (a) guidance towards an organisation of events in the classroom that included regular teacher–student dialogue (b) modelling of the more dialogic form of discourse. 相似文献

This paper addresses the role of classroom discourse in supporting children’s learning in Kenyan primary schools. The discourse strategies of 27 teachers teaching English, mathematics and science across the primary phase were intensively studied using discourse analysis and semi‐structured interviews. A survey questionnaire (n?=?359) was also used to explore teacher perceptions of classroom discourse practices. The findings revealed the dominance of teacher‐led recitation in which rote and repetition dominated the classroom discourse with little attention being paid to securing pupil understanding. The wider implications of the findings for improving the quality of classroom discourse in Kenyan primary schools are considered together with the need for further research into how the wider social order is influencing discourse practices in Kenyan primary schools. 相似文献

Formative assessment, bilingualism, and argumentation when combined can enrich bilingual scientific literacy. However, argumentation receives little attention in the practice of bilingual science education. This article describes the effect of a formative assessment-based pedagogical strategy in promoting university students’ argumentation. It examines the written and oral arguments produced by 54 undergraduates (28 females and 26 males, 16–21 years old) in Colombia during a university bilingual (Spanish-English) science course. The data used in this analysis was derived from students’ written responses, and audio and video recordings. The first goal of this study was to determine how this teaching strategy could help students increase the use of English as a means of communication in argumentation in science. The second goal was to establish the potential of the strategy to engage students in argumentative classroom interactions as an essential part of formative assessment. The findings show that the strategy provided participants with opportunities to write their argumentation in Spanish, in English and in a hybrid version using code-switching. Educational implications for higher education are discussed. 相似文献

The purpose of this study is to examines the relationship between the communicative approach of classroom talk and the modes of representations used by science teachers. Based on video data from two physics classrooms in Singapore, a recurring pattern in the relationship was observed as the teaching sequence of a lesson unfolded. It was found that as the mode of representation shifted from enactive (action based) to iconic (image based) to symbolic (language based), there was a concurrent and coordinated shift in the classroom communicative approach from interactive–dialogic to interactive–authoritative to non-interactive–authoritative. Specifically, the shift from enactive to iconic to symbolic representations occurred mainly within the interactive–dialogic approach while the shift towards the interactive–authoritative and non-interactive–authoritative approaches occurred when symbolic modes of representation were used. This concurrent and coordinated shift has implications on how we conceive the use of representations in conjunction with the co-occurring classroom discourse, both theoretically and pedagogically. 相似文献

For students to meaningfully engage in science practices, substantive changes need to occur to deeply entrenched instructional approaches, particularly those related to classroom discourse. Because teachers are critical in establishing how students are permitted to interact in the classroom, it is imperative to examine their role in fostering learning environments in which students carry out science practices. This study explores how teachers describe, or frame, expectations for classroom discussions pertaining to the science practice of argumentation. Specifically, we use the theoretical lens of a participation framework to examine how teachers emphasize particular actions and goals for their students' argumentation. Multiple-case study methodology was used to explore the relationship between two middle school teachers' framing for argumentation, and their students' engagement in an argumentation discussion. Findings revealed that, through talk moves and physical actions, both teachers emphasized the importance of students driving the argumentation and interacting with peers, resulting in students engaging in various types of dialogic interactions. However, variation in the two teachers' language highlighted different purposes for students to do so. One teacher explained that through these interactions, students could learn from peers, which could result in each individual student revising their original argument. The other teacher articulated that by working with peers and sharing ideas, classroom members would develop a communal understanding. These distinct goals aligned with different patterns in students' argumentation discussion, particularly in relation to students building on each other's ideas, which occurred more frequently in the classroom focused on communal understanding. The findings suggest the need to continue supporting teachers in developing and using rich instructional strategies to help students with dialogic interactions related to argumentation. This work also sheds light on the importance of how teachers frame the goals for student engagement in this science practice. 相似文献

Building on the ‘questioning-based discourse analytical’ framework developed by Singapore-based science educator and discourse analyst, Christine Chin, this study investigated the extent to which fifth-grade science teachers' use of questions with either an authoritative or dialogic orientation differentially restricted or expanded the quality and complexity of student responses in the USA. The author analyzed approximately 10 hours of classroom discourse from elementary science classrooms organized around inquiry-based science curricula and texts. Teacher questions and feedback were classified according to their dialogic orientation and contextually inferred structural purpose, while student understanding was operationalized as a dynamic interaction between cognitive process, syntacto-semantic complexity, and science knowledge type. The results of this study closely mirror Chin's and other scholars' findings that the fixed nature of authoritatively oriented questioning can dramatically limit students' opportunities to demonstrate higher order scientific understanding, while dialogically oriented questions, by contrast, often grant students the discursive space to demonstrate a greater breadth and depth of both canonical and self-generated knowledge. However, certain teacher questioning sequences occupying the ‘middle ground’ between maximal authoritativeness and dialogicity revealed patterns of meaningful, if isolated, instances of higher order thinking. Implications for classroom practice are discussed along with recommendations for future research. 相似文献

Adopting a sociocultural perspective, we construct a case study exploring how a middle school bilingual science teacher reflected and acted when engaged in dialogue, co-teaching, and a newly designed unit on plate tectonics. Sources of data include video of classroom interaction and audio recordings of daily debriefs between the bilingual science teacher and second author. Dialogic reflections between these individuals reveal how the new curriculum, the dialogue, and co-teaching with the second author mediated the teacher’s emerging abilities to think and act in different ways at that sociohistorical moment in time. Based on these findings, we highly encourage professional development experiences to include ongoing dialogic reflection and co-teaching to “shake” teachers’ views and practice. These initial connections can indicate inroads into helping teachers broaden understanding of bilingual science education.

This ethnographic study of a third grade classroom examined elementary school science learning as a sociocultural accomplishment.
The research focused on how a teacher helped his students acquire psychological tools for learning to think and engage in
scientific practices as locally defined. Analyses of classroom discourse examined both how the teacher used mediational strategies
to frame disciplinary knowledge in science as well as how students internalized and appropriated ways of knowing in science.
The study documented and analyzed how students came to appropriate scientific knowledge as their own in an ongoing manner
tied to their identities as student scientists. Implications for sociocultural theory in science education research are discussed.

ABSTRACTReform initiatives around the world are reconceptualising science education by stressing student engagement in science practices. Yet, science practices are language-intensive, requiring students to have strong receptive and productive language proficiencies. It is critical to address these rigorous language demands to ensure equitable learning opportunities for all students, including English language learners (ELLs). Little research has examined how to specifically support ELL students’ engagement in science practices, such as argumentation. Using case-study methodology, we examined one middle school science teacher's instructional strategies as she taught an argumentation-focused curriculum in a self-contained ELL classroom. Findings revealed that three trends characterized the teacher’s language supports for the structural and dialogic components of argumentation: (1) more language supports focused on argument structure, (2) dialogic interactions were most often facilitated by productive language supports, and (3) some language supports offered a rationale for argumentation. Findings suggest a need to identify and develop supports for the dialogic aspects of argumentation. Furthermore, engaging students in argumentation through productive language functions could be leveraged to support dialogic interactions. Lastly, our work points to the need for language supports that make the rationale for argumentation explicit since such transparency could further increase access for all students. 相似文献

The national science standards, along with prominent researchers, call for increased focus on scientific argumentation in the classroom. Over the past decade, researchers have developed sophisticated online science learning environments to support these opportunities for scientific argumentation. Assessing the quality of dialogic argumentation, however, has proven challenging. Existing analytic frameworks assess dialogic argumentation in terms of the nature of students' discourse, formal argumentation structure, interactions, and epistemic forms of reasoning. Few frameworks, however, connect these assessments to conceptual quality. We present an analytic framework for assessing argumentation in online science learning environments that relates levels of opposition with discourse moves, use of grounds, and conceptual quality. We then apply the proposed framework to students' dialogic argumentation within a representative online science learning environment to investigate the framework's potential affordances as well as to assess issues of reliability and appropriateness. The results suggest that the framework offers significant affordances and that it also offers high interrater reliability for trained coders. The applicability of the framework for offline contexts and future extensions of the framework are discussed in light of these results. © 2007 Wiley Periodicals, Inc.

Research into classroom interactions has shown that talk that promotes reasoning can help children in their learning of science. Such talk can only be generated when teachers are willing to take a dialogic approach that is stimulating and provides opportunities for children to articulate their ideas. This research set out to determine whether the use of large puppets would help teachers to change the nature of their whole class discourse to enhance children’s talk and engagement in science. The study was carried out with sixteen teachers of children aged 7–11 years in schools in London and Manchester, UK. Through adopting a mixture of research methods, including classroom observation and teacher and child interviews, the research provides evidence that the use of puppets significantly increases the amount of teacher discourse oriented towards reasoning and argument, and decreases the amount of talk that focuses on recall. Through the puppets, teachers also use more narrative to set the science in stimulating contexts, and encourage children in their contributions to whole class discussion. Interview data also show the positive effects of puppets on children’s motivation and engagement in science. The findings have led to further major funding for professional development in the use of puppets in the UK, and research into the reasons why the use of puppets is so effective. 相似文献

Dialogue, as a communication form characterized by its commitment to inclusiveness and rationality, has long been advocated by educators as a mechanism for helping students become better thinkers. Unfortunately, numerous claims about the educational potential of participating in dialogue have not resulted in substantial changes in classroom practices. Studies have consistently shown that in today's schools the dominant discourse remains largely monologic. In this article, we present a testable theory of change that suggests how sociocultural processes in a dialogic classroom influence students’ development. We identify and discuss three learning outcomes of dialogic teaching, including epistemological understanding, argument skills, and disciplinary knowledge. We then critically review empirical research related to the proposed theory, highlighting unsolved questions, inconsistencies, and directions for future studies. Finally, we focus on the implications of the proposed integrated theory and reviewed research for teachers and their language use in a classroom. 相似文献

This article considers what is meant by ‘interactive whole‐class teaching’, a central component of the British Government's primary and secondary Literacy Strategies. Drawing on published research evidence and a case‐study undertaken in a London comprehensive school, this essay suggests that contradictions in government policy have led to an increase in the kind of whole‐class teaching which offers an impoverished model of classroom discourse. Alternative models of pupil–teacher interaction are discussed. However, the article concludes that the current ideological imperative to deliver a literacy ‘quick‐fix’ is inimical to the conditions necessary to foster genuinely dialogic classroom talk. 相似文献

This study offers an insight into the experiences of three newly qualified English primary teachers and their pupils as they sought to develop dialogic teaching in lessons. It draws upon a range of literature from the field of classroom talk, with a particular focus on the work of Robin Alexander to underpin teacher/researcher professional discussion and analysis of periodic video recordings of talk in these classrooms. Supplemented by teacher interviews, the research examines the extent to which a dialogic approach to teacher professional development might facilitate teacher self‐evaluation as a means of developing a more dialogic classroom. In doing so, it seeks to exemplify key talk moves (dialogic bids) that these teachers used to open up dialogic spaces in lessons. The research concludes that raising teacher awareness of such talk moves through professional discussion and reflection upon teaching can provide teachers with a metacognitive resource for talking about and furthering dialogic teaching practices. 相似文献
