Current science education reforms highlight the importance of students making sense of scientific ideas. While research has studied how to support sensemaking in classrooms, we still know very little about what drives students to pursue and persist in it on their own. In this article, we use a set of parallel case studies of undergraduate students discussing introductory physics to show how certain student-generated, vexing questions both initiate and sustain students' sensemaking processes. We examine affective and linguistic markers in student discourse in paired-clinical interviews to demonstrate both of these functions of vexing questions and detail their role in the explanations students construct. We conclude by discussing the implications of this analysis both for supporting sensemaking in classrooms and for studying it in research.  相似文献

In this study we present an analysis of classroom interactions initiated by students' wonderment questions. Our interest in such events arises from their potential to stimulate active intellectual engagement in classrooms, which can impact upon the subsequent development of the classroom discourse. In investigating this issue we shall address the following research question: How do student questions impact upon the teaching explanatory structure and modify the form of the ongoing classroom discourse, in selected science lessons? From data collected in a Brazilian secondary school we have selected three classroom episodes, with large differences in both the context in which the student's question emerges and in the communicative approach developed in response to it. The analysis, based on the framework proposed by Mortimer and Scott [Mortimer and Scott (2003). Meaning making in secondary science classrooms. Maidenhead: Open University Press], shows that questions made by students are important in providing feedback from students to the teacher, enabling adjustments to the teaching explanatory structure. These adjustments sometimes occur smoothly, at other times with major changes to the features of the classroom discourse, and elsewhere with misunderstanding and disagreement. The data also suggest the need to consider students' intentions and their active participation in the negotiation of both the content and structure of classroom discourse. © 2009 Wiley Periodicals, Inc.

Science teachers and educators seek to promote equity and inclusion within their classrooms. Yet, many do not examine how their roles could reproduce oppression that continues to exclude certain groups of students. Centering on how oppression interacts with science teaching and learning, this naturalistic study observed Ms. William and her implementation of two STEM units that integrate science and engineering, to understand power, race, and privilege dynamics in her middle school STEM classrooms. Specifically, we focused on understanding oppression at the interpersonal and internalized level in Ms. William's class. We collected and analyzed video recorded lessons from two different classrooms, two STEM curricula Ms. William had co-developed, and conducted semi-structured interviews after she taught her two STEM units. We identified themes of oppression perpetuated in the classroom by employing thematic analysis, which when guided by our theoretical framework enabled us to illuminate the complex relationship between science teaching and maintaining whiteness as the dominant discourse in science learning. Our findings suggest that an active and critical role from science teachers and educators are required; we must reflect deeply on our science curriculum and teaching strategies and identify practices that remains to be oppressive if promoting equity and inclusion is at the forefront of our science teaching.  相似文献

The purpose of this cross-case analysis is to illustrate how and why literacy was incorporated into science teaching and learning in three secondary classrooms. Research questions guiding the analysis include: (a) How were literacy events shaped by the teachers' philosophies about teaching science content and teaching students? and (b) How was literacy (reading, writing, and oral language) structured by the teachers and manifested in science lessons? The methodology of ethnography and the theoretical framework of symbolic interactionism were employed in the three studies on which the cross-case analysis was based. The researchers assumed the role of participant observers, collecting data over the period of 1 year in each of the three classrooms. Data, in the form of fieldnotes, interviews, and artifacts, were collected. In each study, data were analyzed using the constant comparative method (Glaser & Strauss, 1967) to determine patterns in the teachers' beliefs about learning and how these influenced their choice of literacy activities. The cross-case analysis was conducted to determine patterns across the three teachers and their classrooms. The findings from this analysis are used to compare how the teachers' philosophies of teaching science and their beliefs about how students learn influenced their use of literacy practices during lessons. Specifically, each teacher's use of literacy activities varied based on his or her beliefs about teaching science concepts. Furthermore, reading, writing, and oral language were important vehicles to learning science concepts within daily classroom activities in the three classrooms.  相似文献

Although research has come to recognize the importance of studying classroom-based student–teacher discourse in science, the emphasis remains largely on teachers' abilities to ask questions and provide students with feedback, or on students' abilities to ask questions or engage in argumentative discourse. Consequently, little research has focused on the discourse elements relating to teacher–student discourse interactions. In this article, we argue for a shift of research attention toward describing what the teacher is responding to (Identification of student inquiry), the process of deciding how to respond (Interpretation—Evaluation of student inquiry), and how the teacher is responding (Response to student inquiry). We propose a new methodological approach for studying teacher discourse, which involves a framework we developed while analyzing 1,385 minutes of fifth grade, whole-class science conversations covering a 2-year period and facilitated by an experienced science teacher. Then, as a case in point, we applied our framework to the teacher discourse data of the study, aiming to show that the framework can be a useful tool for examining how a teacher supports students' inquiry.  相似文献

This study explores the process of teacher scaffolding student engagement in epistemic tools from the critical sensemaking perspective. Epistemic tools are contextual artifacts manipulated to investigate and evaluate ideas to construct knowledge within the constraints of a disciplines' representational means. The main sources of our data are ~50 min-long semistructured, responsive interviews with the 14 secondary school science teachers who participated in our professional learning environment (PLE) and implemented the activities from the PLE in their classrooms. We utilized the tools of discourse analysis to explore teacher sensemaking while they learned to teach science with epistemic tools. We then looked at intertextualities of meaning across multiple sets of data such as students' artifacts, pre/postsurveys, audio and video recordings of the workshops, and teachers' written implementation feedback forms. As a result, we recognized a pattern across different classrooms. Teachers would begin with a contextualized goal, and use a pedagogical strategy to scaffold their students as they worked to achieve that goal. Then, all teachers reported they faced some sort of ambiguity (such as grappling with failure, different levels of students). When faced with an ambiguity, teachers would then revise either their contextualized goal or their initial pedagogical strategy to help their students to reach their goals. Finally, we utilized constant-comparative analysis to identify themes for teachers' contextualized goals. Four major themes emerged, including communicating connections to core ideas of science, making sense of how science works, assessing students' learning process outcomes, and fostering students' epistemic agency. The findings of the study have implications for future research and professional development activities on the use of epistemic practices and tools in classrooms with unique contextual characteristics.  相似文献

This study examined how, in some instances, participation in the cultural practices of high school science classrooms created intrapersonal conflict for ethnic minority students. Discourse analysis of videotaped science classroom activities, lectures, and laboratories was the primary methodology employed for analyzing students' discursive identity development. This analysis demonstrated differential appropriation of science discourse as four significant domains of discursive identities emerged: Opposition status, Maintenance status, Incorporation status, and Proficiency status. Students characterized as Opposition Status avoided use of science discourse. Students who exhibited Maintenance Status illustrated a commitment to maintaining their normative discourse behavior, despite a demonstrated ability to appropriate science discourse. Students characterized as Incorporation Status made active attempts to incorporate science discourse into their normative speech patterns, while Proficiency Status students demonstrated a fluency in applying scientific discursive. Implications for science education emerging from the study include the illumination of the need to make the use of specific scientific discourse an explicit component of classroom curriculum. © 2004 Wiley Periodicals, Inc.

In this study, we analyzed the quality of students' written scientific explanations found in notebooks and explored the link between the quality of the explanations and students' learning. We propose an approach to systematically analyzing and scoring the quality of students' explanations based on three components: claim, evidence to support it, and a reasoning that justifies the link between the claim and the evidence. We collected students' science notebooks from eight science inquiry‐based middle‐school classrooms in five states. All classrooms implemented the same scientific‐inquiry based curriculum. The study focuses on one of the implemented investigations and the students' explanations that resulted from it. Nine students' notebooks were selected within each classroom. Therefore, a total of 72 students' notebooks were analyzed and scored using the proposed approach. Quality of students' explanations was linked with students' performance in different types of assessments administered as the end‐of‐unit test: multiple‐choice test, predict‐observe‐explain, performance assessment, and a short open‐ended question. Results indicated that: (a) Students' written explanations can be reliably scored with the proposed approach. (b) Constructing explanations were not widely implemented in the classrooms studied despite its significance in the context of inquiry‐based science instruction. (c) Overall, a low percentage of students (18%) provided explanations with the three expected components. The majority of the sample (40%) provided only claims without any supporting data or reasoning. And (d) the magnitude of the correlations between students' quality of explanations and their performance, were all positive but varied in magnitude according to the type of assessment. We concluded that engaging students in the construction of high quality explanations may be related to higher levels of student performance. The opportunities to construct explanations in science‐inquiry based classrooms, however, seem to be limited. © 2010 Wiley Periodicals, Inc. J Res Sci Teach 47: 583–608, 2010  相似文献

In this article, we examine the oral and written discourse processes in a high school physics class and how these discourse processes are related to sociocultural practices in scientific communities. Our theoretical framework is based on sociological and anthropological studies of scientific communities and ethnographies of classroom life. We review the use of discourse analysis as a methodological orientation in science education and provide a logic‐of‐inquiry framing how we used discourse analysis in our ethnographic research. Our ethnographic analysis showed that, through students' participation in creating scientific papers on the physics of sound, their appropriation of scientific discourse was related to the framing activities of the teachers and the social practices established over time in the classroom. Our textual analysis of the student papers focused on how they used evidence to make claims. We explore the lessons learned from participating in the classroom of these students. © 1999 John Wiley & Sons, Inc. J Res Sci Teach 36: 883–915, 1999  相似文献

Not understanding is central to scientific work: what scientists do is learn about the natural world, which involves seeking out what they do not know. In classrooms, however, the position of not‐understanding is generally a liability; confusion is an unfortunate condition to resolve as quickly as possible, or to conceal. In this article, we argue that students' public displays of uncertainty or confusion can be pivotal contributions to the classroom dynamics in initiating and sustaining a class's science inquiry. We present this as a central finding from a cross‐case analysis of eight episodes of students' scientific engagement, drawing on literature on framing to show how participants positioned themselves as not‐understanding and how that was consequential for the class's scientific engagement. We show how participants enacted this positioning by asking questions or expressing uncertainty around a phenomenon or model. We then analyze how participants' displays of not‐understanding shaped the conceptual, epistemic, and social aspects of classroom activity. We present two cases in detail: one in which a student's positioning helped initiate the class's scientific engagement and another in which it helped sustain it. We argue that this work motivates considering how to help students learn to embrace and value the role of expressing one's confusion in science.  相似文献

One of the challenges for analysing science classroom discourse is a better understanding of intercontextual relationships in the learning process. In this paper, we used orientations from ethnography in education to organise and propose an analytical metaphor called the hourglass approach. It involves three phases of analysis that correspond to the parts of the hourglass. The first phase involves obtaining a continuous cross section of classroom history and the intersections between sociocultural contexts and the science learning contexts, throughout this track record. The second phase involves discourse analysis of few selected events is the vertex of the hourglass. Finally, in the third phase, the analysis of interactions is focused on intercontextual relationships for the interpretation of science learning opportunities. We illustrate this approach based on interactions during science lessons in a first-grade class. In particular, we discuss, in greater detail, how a meaningful intercontextual element in the participants’ group (i.e. the gender norm), intermingled with the engagement of students in practices from the conceptual, epistemic and social domains of scientific knowledge.

Many state and federal governments have mandated in such documents as the National Science Education Standards that inquiry strategies should be the focus of the teaching of science within school classrooms. The difficult part for success is changing teacher practices from perceived traditional ways of teaching to more inquiry‐based approaches. Arguments are often made about the effectiveness of these traditional strategies. The purpose of this study was to compare the effectiveness of the inquiry‐based approach known as the Science Writing Heuristic approach as a treatment to traditional teaching practices on students' post‐test scores in relation to students' achievement level and teacher's implementation of the approach. A mixed‐method research approach was used to analyze the teacher observational data and students' test results. The major findings of this study are that the quality of the implementation does have an impact on student performance on post‐test scores and that high‐quality implementation of the Science Writing Heuristic approach has significant advantages in closing the achievement gap within science classrooms.  相似文献

This methodological paper presents an approach for examining emotional expressions through discourse analysis and ethnographic methods. Drawing on trends in the current literature in science education, we briefly explain the importance of emotions in science education and examine the current research methodologies used in interactional emotion studies. We put forth and substantiate a methodological approach that attends to the interactional, contextual, intertextual, and consequential aspects of emotional expressions. By examining emotional expressions in the discourse in which they are constructed, emotional expressions are identified through semantics, contextualization, and linguistic features. These features make salient four dimensions of emotional expressions: aboutness, frequency, type, and ownership. Drawing on data from a large empirical study of pre-service elementary teachers’ emotional expressions about climate change in a science course, we provide illustrative examples to describe what counts as emotional expressions in situ. In doing so we explain how our approach makes salient the nuanced nature of such expressions as well as the broader discourse in which they are constructed and the implications for researching emotional expressions in science education discourse. We suggest reasons why this discourse orientated research methodology can contribute to the interactional study of emotions in science education contexts.  相似文献

This article characterizes “engagement in science learning” from a sociocultural perspective and offers a mixed method approach to measuring engagement that combines critical discourse analysis (CDA) and social network analysis (SNA). Conceptualizing engagement from a sociocultural perspective, the article discusses the advantages of a mixed methodological approach, and specifically how mixed methods can expand and enrich our understanding of engagement in certain science learning situations. Through this sociocultural viewpoint, engagement is defined as meaningful changes in disciplinary discourse practice, which captures the dialectical relationship between the individual and collective. The combined use of CDA and SNA integrates an individual's relative position in a group with her situated language use.  相似文献

In this study, an anthropological perspective informed by sociolinguistic discourse analysis was used to examine how teachers, students, and scientists constructed ways of investigating and knowing in science. Events in a combined fourth‐ and fifth‐grade elementary class were studied to document how the participating teacher provided opportunities for students to diverge from the intended curriculum to pursue their questions concerning the behavior of sea animals in a marine science observation tank. Analysis of the classroom discourse identified ways that particular teaching strategies provided opportunities for student engagement in scientific practices. Implications of this study for the teaching of science in elementary classrooms include the value of student‐initiated science explorations under the conditions of uncertainty and for topics in which the teacher lacked relevant disciplinary knowledge. © 2000 John Wiley & Sons, Inc.

Recent instructional reforms in science education aim to change the way students engage in learning in the discipline, as they describe that students are to engage with disciplinary core ideas, crosscutting concepts, and the practices of science to make sense of phenomena (NRC, 2012). For such sensemaking to become a reality, there is a need to understand the ways in which students' thinking can be maintained throughout the trajectory of science lessons. Past research in this area tends to foreground either the curriculum or teachers' practices. We propose a more comprehensive view of science instruction, one that requires attention to teachers' practice, the instructional task, and students' engagement. In this study, by examining the implementation of the same lesson across three different classrooms, our analysis of classroom videos and artifacts of students' work revealed how the interaction of teachers' practices, students' intellectual engagement, and a cognitively demanding task together support rigorous instruction. Our analyses shed light on their interaction that shapes opportunities for students' thinking and sensemaking throughout the trajectory of a science lesson. The findings provide implications for ways to promote rigorous opportunities for students' learning in science classrooms.  相似文献

In this paper, we report findings from a discourse analysis study of reading instruction in eight primary/elementary school classrooms in the United States. Drawing upon discursive psychology, we specifically examined 96 hours of reading comprehension instruction, with a focus on how teachers talked about the body during the instruction and noted how this gave rise to particular constructions of what it means to be a ‘good’ reader and/or learner. We discuss two patterns from the analysis of our data, including: (1) emphasized versus embedded physical control as essential to being a ‘successful’ reader, and (2), implicit physical control and freedom as essential to literacy learning and to students' identities as readers. We conclude by highlighting implications, with a focus on student identity.  相似文献
