Argumentation and scientific discourse are essential aspects of science education and inquiry in the 21st century. Student groups often struggle to enact these critical science skills, particularly with challenging content or tasks. Social regulation of learning research addresses the ways groups attempt to navigate such struggles by collectively planning, monitoring, controlling, and reflecting upon their learning in collaborative settings. Such regulation and argumentation can also elicit socioemotional responses and interactions. However, little is known regarding how regulation processes and socioemotional interactions manifest among students involved in small-group discourse about scientific phenomena. As such, in this qualitative study, we explored social regulation of learning, scientific argumentation discourse, and socioemotional interactions in the discussions of two groups of high school physics students (n = 7, n = 6). We found key qualitative distinctions between the two groups, including how they enacted planning activities, their emphasis on challenging other’s ideas versus building shared understanding, and how socioemotional interactions drove discourse. Commonalities across groups included how regulation initiation related to discourse, as well as how the difficulty of the content hindered, and teacher support augmented, the enactment of social regulation. Finally, we found overlapping regulation and discourse codes that provide a foundation for future work.  相似文献

Background: Science educators have sought to structure collaborative inquiry learning through the assignment of static group roles. This structural approach to student grouping oversimplifies the complexities of peer collaboration and overlooks the highly dynamic nature of group activity.

Purpose: This study addresses this issue of oversimplification of group dynamics by examining the social leadership structures that emerge in small student groups during science inquiry.

Sample: Two small student groups investigating the burning of a candle under a jar participated in this study.

Design and method: We used a mixed-method research approach that combined computational discourse analysis (computational quantification of social aspects of small group discussions) with microethnography (qualitative, in-depth examination of group discussions).

Results: While in one group social leadership was decentralized (i.e., students shared control over topics and tasks), the second group was dominated by a male student (centralized social leadership). Further, decentralized social leadership was found to be paralleled by higher levels of student cognitive engagement.

Conclusions: It is argued that computational discourse analysis can provide science educators with a powerful means of developing pedagogical models of collaborative science learning that take into account the emergent nature of group structures and highly fluid nature of student collaboration.  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 reflective processes by which a grade 5 science community co-constructed shared inquiry structures to focus and guide its inquiry about human body systems over a school year supported by a collaborative online environment. The co-constructed structures included a list of collective wondering areas as the shared focus of inquiry and models of the inquiry process in the form of “research cycle.” Qualitative analyses of field notes, classroom videos, student notebooks and interviews elaborate the evolution of the inquiry areas and the “research cycle” model as well as students’ adaptive use of the structures to guide deeper inquiry. Content analyses of students’ individual research questions and collaborative online discourse indicate that students used the structures to develop more advanced inquiry and make productive contributions. The results contribute to elaborating a reflective structuration approach to co-organizing and sustaining long-term, open-ended inquiry in knowledge building communities.  相似文献

This study examined the role of computer-supported knowledge-building discourse and epistemic reflection in promoting elementary-school students’ scientific epistemology and science learning. The participants were 39 Grade 5 students who were collectively pursuing ideas and inquiry for knowledge advance using Knowledge Forum (KF) while studying a unit on electricity; they also reflected on the epistemic nature of their discourse. A comparison class of 22 students, taught by the same teacher, studied the same unit using the school’s established scientific investigation method. We hypothesised that engaging students in idea-driven and theory-building discourse, as well as scaffolding them to reflect on the epistemic nature of their discourse, would help them understand their own scientific collaborative discourse as a theory-building process, and therefore understand scientific inquiry as an idea-driven and theory-building process. As hypothesised, we found that students engaged in knowledge-building discourse and reflection outperformed comparison students in scientific epistemology and science learning, and that students’ understanding of collaborative discourse predicted their post-test scientific epistemology and science learning. To further understand the epistemic change process among knowledge-building students, we analysed their KF discourse to understand whether and how their epistemic practice had changed after epistemic reflection. The implications on ways of promoting epistemic change are discussed.  相似文献

To help explain the differences in students' performance on internationally administered science assessments, cross-national, video-based observational studies have been advocated, but none have yet been conducted at the elementary level for science. The USA and Germany are two countries with large formal education systems whose students underperform those from peers on internationally administered standardized science assessments. However, evidence from the 2011 Trends in International Mathematics and Science Exam assessment suggests fourth-grade students (9–10 year-olds) in the USA perform higher than those in Germany, despite more instructional time devoted to elementary science in Germany. The purpose of this study is to comparatively analyze fourth-grade classroom science in both countries to learn more about how teachers and students engage in scientific inquiry, particularly explanation-construction. Videorecordings of US and German science instruction (n 1?=?42, n 2?=?42) were sampled from existing datasets and analyzed both qualitatively and quantitatively. Despite German science lessons being, on average, twice as long as those in the USA, study findings highlight many similarities between elementary science in terms of scientific practices and features of scientific inquiry. However, they also illustrate crucial differences around the scientific practice of explanation-construction. While students in German classrooms were afforded more substantial opportunities to formulate evidence-based explanations, US classrooms were more strongly characterized by opportunities for students to actively compare and evaluate evidence-based explanations. These factors may begin to help account for observed differences in student achievement and merit further study grounded in international collaboration.  相似文献

Teacher education programs have adopted preparing science teachers that teach science through inquiry as an important pedagogic agenda. However, their efforts have not met with much success. While traditional explanations for this failure focus largely on preservice science teachers’ knowledge, beliefs and conceptions regarding science and science teaching, this conceptual paper seeks to direct attention toward discursive practices surrounding inquiry science teaching in teacher education programs for understanding why most science teachers do not teach science through inquiry. The paper offers a theoretical framework centered on critical notions of subjection and performativity as a much needed perspective on making/becoming of science teachers through participation in discursive practices of science teacher education programs. It argues that research based on such perspectives have much potential to offer a deeper understanding of the difficult challenges teacher education programs face in preparing inquiry practicing science teachers.  相似文献

In this piece, Elizabeth Moje discusses with the authors of FORUM: Giving oneself over to science: Exploring the roles of subjectivities and identities in learning science (Tucker-Raymond, Varelas, & Pappas) the challenges and potentials of theorizing about the role of identities in learning science. The authors debate how identities and subjectivities should be conceptualized, and whether learning science requires people to change identities and/or subjectivities. In particular, the authors discuss the potential for thinking about how identities are enacted in practices, and how teachers might construct practices that evoke the identities associated with science as a way of developing opportunities for deep science learning. Elizabeth Birr Moje is an Arthur F. Thurnau Professor of Literacy, Language, and Culture in Educational Studies, a Faculty Associate in the Institute for Social Research and a faculty affiliate with Latina/o Studies at the University of Michigan, Ann Arbor. Moje teaches undergraduate and graduate courses in secondary and adolescent literacy, cultural theory, and qualitative research methods. Her research interests revolve around the intersection between the literacies and texts youth are asked to learn in the disciplines and the literacies and texts they engage outsIDe of school. Moje also studies how youth construct cultures and enact IDentities via their literacy practices outsIDe of school. Eli Tucker-Raymond is a doctoral student in the Literacy, Language, and Culture program at the University of Illinois at Chicago. He sees his evolving status as a social scientist fraught with similarities and differences between himself and social scientists “out in the world.' He is working toward a designated researcher and teacher IDentity that includes a focus on critical media literacy, collaborative action research, and developing praxis-oriented, critically-conscious learning communities in urban K-8 school settings. One evolutionary, co-constructed step toward that IDentity are these publications, his first. Maria Varelas is Professor of Science Education at the University of Illinois at Chicago. Her research, teaching, and service are highly interrelated, focusing on classroom-based teaching and learning of science in urban settings with linguistically and socio-culturally diverse populations, collaborative teacher action research, discourse in science classrooms, integration of science and literacy, and science education reform in elementary school and college science classrooms. She currently co-leads with colleagues in Education, Natural Sciences, and Computer Science, three US NSF multi-year grants. Her research has appeared in a variety of journals and edited books. Christine C. Pappas is Professor of Language and Literacy at the University of Illinois at Chicago.

This study describes the characteristics of pre-service teachers’ discourse on a WebCT Bulletin Board in their investigations of local streams in an integrated mathematics and science course. A qualitative analysis of data revealed that the pre-service teachers conducted collaborative discourse in framing their research questions, conducting research and writing reports. The science teacher educator provided feedback and carefully crafted prompts to help pre-service teachers develop and refine their work. Overall, the online discourse formats enhance out-of-class communication and support collaborative group work. But the discourse on the critical examination of one another’s point of views rooted in scientific inquiry appeared to be missing. It is suggested that pre-service teachers should be given more guidance and opportunities in science courses in carrying out scientific discourse that reflects reform-based scientific inquiry.  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

To a science ‘outsider’, science language often appears unnecessarily technical and dense. However, scientific language is typically used with the goal of being concise and precise, which allows those who regularly participate in scientific discourse communities to learn from each other and build upon existing scientific knowledge. One essential component of science language is the academic vocabulary that characterises it. This mixed-methods study investigates middle school students’ (N?=?59) growth in academic vocabulary as it relates to their teacher’s instructional practices that supported academic language development. Students made significant gains in their production of general academic words, t(57)?=?2.32, p?=?.024 and of discipline-specific science words, t(57)?=?3.01, p?=?.004 in science writing. Results from the qualitative strand of this inquiry contextualised the students’ learning of academic vocabulary as it relates to their teacher’s instructional practices and intentions as well as the students’ perceptions of their learning environment. These qualitative findings reveal that both the students and their teacher articulated that the teacher’s intentional use of resources supported students’ academic vocabulary growth. Implications for research and instruction with science language are shared.  相似文献

The demographic changes in Greek schools underline the need for reconsidering the way in which migrant pupils move from their everyday culture into the culture of school science (a process known as “cultural border crossing”). Migrant pupils might face difficulties when they attempt to transcend cultural borders and this may influence their progress in science as well as the construction of suitable academic identities as a means of promoting scientific literacy. In the research we present in this paper, adopting the socioculturally driven thesis that learning can be viewed and studied as a meaning-making, collaborative inquiry process, we implemented an action research program (school year 2008–2009) in cooperation with two teachers, in a primary school of Athens with 85% migrant pupils. We examined whether the two teachers, who became gradually acquainted with cross-cultural pedagogy during the project, act towards accommodating the crossing of cultural borders by implementing a variety of inclusive strategies in science teaching. Our findings reveal that both teachers utilized suitable cross-border strategies (strategies concerning the establishment of a collaborative inquiry learning environment, and strategies that were in accordance with a cross-border pedagogy) to help students cross smoothly from their “world” to the “world of science”. A crucial key to the teachers’ expertise was their previous participation in collaborative action research (school years 2004–2006), in which they analyzed their own discourse practices during science lessons in order to establish more collaborative inquiry environments.  相似文献

Phenomena associated with the pendulum present numerous opportunities for assessing higher order human capabilities related to scientific inquiry and the discovery of natural law. This paper illustrates how systematic assessment of scientific inquiry capabilities, using pendulum phenomena, can provide a useful tool for classroom teachers and program planners. Structured inquiry, a technique of teacher-facilitated student inquiry involving direct interaction between students and natural phenomena, is presented as a way to establish student competence in applying scientific inquiry capabilities (e.g., conceptualizing variation due to error). This approach to assessment can heighten student curiosity and provide a concrete referent for complementary cultural, historical, and scientific instruction. The role of assessment in constructively shaping science education programs is considered.  相似文献

Preparing data-literate citizens and supporting future generations to effectively work with data is challenging. Engaging students in Knowledge Building (KB) may be a promising way to respond to this challenge because it requires students to reflect on and direct their inquiry with the support of data. Informed by previous studies, this research explored how an analytics-supported reflective assessment (AsRA)-enhanced KB design influenced 6th graders' KB and data science practices in a science education setting. One intact class with 56 students participated in this study. The analysis of students' Knowledge Forum discourse showed the positive influences of the AsRA-enhanced KB design on students' development of KB and data science practices. Further analysis of different-performing groups revealed that the AsRA-enhanced KB design was accessible to all performing groups. These findings have important implications for teachers and researchers who aim to develop students' KB and data science practices, and general high-level collaborative inquiry skills.

To keep intuitive knowledge fluid for an extended time, we wish to encourage young children to examine continuously those intuitive explanations for natural phenomena which later become hard wired, highly resistant to development or change. To assist this we designed a learning package which integrated three extensively researched educational strategies (cooperative learning, informal inquiry and familiar context) for children to explore their notions about the topiclight. Children in a kindergarten class were encouraged to share their ideas about shadows and shadow formation with peers, as they took part in explorations of shadow formation inside and outside their classroom. Whole class discussions, small group conversations and final conversations between researcher and small groups provide insights into social and individual construction of knowledge, young children's abilities to be scientific and the social construction of gender. Specializations: children's learning in science and technology; inclusion; contexts, teaching models.  相似文献

In this study, we argue that a teacher has a crucial role in leading students into collaborative inquiry‐learning practices. While many studies have given the impression that students are able to engage in inquiry processes on their own, the role of social practices and teacher guidance often remains unexplained. However, even when the pedagogical setting is organized toward collaboration and student‐driven inquiry, it does not mean that students will, as a matter of course, collaborate and take collective responsibility for their own learning. This research has been conducted by a teacher and researchers, and reports on the teacher’s impressions about organizing and promoting a computer‐supported collaborative inquiry process in her classroom of the fourth and fifth grade levels of a Finnish elementary school. The ‘Artifact Project’ was collaboratively designed together by the class teacher and researchers, but the teacher was responsible for implementing and adapting plans in practice. The aim of the ‘Artifact Project – the Past, the Present, and the Future’ – was to support students’ (n = 32) understanding of the diversity of artifacts. Students were asked to analyze artifacts within the cultural context, to study physical phenomena related to them, and to design future artifacts. A collaborative learning environment, Knowledge Forum, facilitated the activities. During the process, the teacher wrote weekly in a reflective project diary. The template of the diary guided the teacher to reflect on the issues that she considered important at the writing moment: the organizing practices, topic content and process stages; how the classroom community functioned; as well as the role of technology as a support for the process. The contents of the diary were analyzed with qualitative content analysis with the help of AtlasTi software. This study depicts an experienced teacher’s practices, her efforts to promote pupils’ cognitive responsibility for advancing their collaborative object‐oriented inquiry process themselves. Instead of trying to control all aspects of pupils’ learning, the teacher assumed the role of an organizer concerning collaborative progressive inquiry and designing activities. Organizing and supporting activities were based on a continuous following of the pupils’ states of process. Knowledge Forum structured the process and mediated activities, and rendered their objects visible and accessible to the whole learning collective. We suggest that in order to expand and scale up advanced inquiry practices, teachers’ usually invisible work in guiding and directing classroom practices has to be made visible and should be analyzed in detail.  相似文献

In this paper we describe our research using a multi-user virtual environment, Quest Atlantis, to embed fourth grade students in an aquatic habitat simulation. Specifically targeted towards engaging students in a rich inquiry investigation, we layered a socio-scientific narrative and an interactive rule set into a multi-user virtual environment gaming engine to establish a virtual world through which students learned about science inquiry, water quality concepts, and the challenges in balancing scientific and socio-economic factors. Overall, students were clearly engaged, participated in rich scientific discourse, submitted quality work, and learned science content. Further, through participation in this narrative, students developed a rich perceptual, conceptual, and ethical understanding of science. This study suggests that multi-user virtual worlds can be effectively leveraged to support academic content learning.  相似文献
