There is now a significant research literature devoted to reconceptualizing scientific activities, such as modeling, explanation, and argumentation, to realize a vision of science-as-practice in classrooms. As yet, however, not all scientific practices have received equal attention. Planning and Carrying out Investigations is one of the eight scientific practices identified in the Next Generation Science Standards, and there is a long line of research from both psychological and science education traditions that addresses topics about investigation, such as the generation and interpretation of evidence. However, investigation has not been subject to concerted reconceptualization within recent research and instructional design efforts focused on science-as-practice. In this article, we propose a framework that centers the investigation as a key locus for constructing alignments among phenomena, data, and explanatory models and makes visible the work that scientists engage in as they develop and stabilize alignments. We argue that these alignments are currently under-theorized and under-utilized in instructional environments. We explore four opportunities that we argue are both accessible to students from a young age and can support conceptual innovation. These are (a) developing empirical systems, (b) getting a grip on empirical systems, (c) determining, defining and operationalizing data as “evidence,” and (d) making sense of what the results of empirical systems do and do not help us understand. 相似文献

Fidelity of implementation (FOI) has received attention in calls for funding and research; however, there are numerous ways of conceptualising and measuring this construct. We argue that this conceptualisation is important for recent reform efforts focused on science practices. Consequently, we explored FOI in the context of the enactment of a middle-school curriculum focused on one particular science practice, argumentation. We coded videos of five teachers’ enactments of argumentation lessons using two different fidelity coding schemes. First, Fidelity to Procedure targeted teachers’ adherence to the order and types of procedures. Second, Fidelity to Goal examined teachers’ adherence to the overarching argumentation goals. This analysis resulted in case studies that illustrate distinct patterns in the teachers’ curriculum enactments. One case in particular, Ms Newbury, received a low score for Fidelity to Procedure, but a high score for Fidelity to Goal. She altered procedures to provide her students, all of whom were English Language Learners, with different linguistic supports, but maintained the overarching argumentation goals. Consequently, we argue that FOI for goals may better capture whether teachers’ enactments are supporting students in the science practices. Furthermore, the results suggest the importance of educative curriculum including rationales for the curricular goals. 相似文献

In recent years, research on students' scientific argumentation has progressed to a recognition of nascent resources: Students can and do argue when they experience the need and possibility of persuading others who may hold competing views. Our purpose in this article is to contribute to this progress by applying the perspective of framing to the question of when and how a class forms and maintains a sense of their activity as argumentative. In particular, we examine three snippets from a sixth‐grade class with respect to how the students—and the teacher—experience, or frame, what is taking place. We argue that they show dynamics of framing for individuals and for the class as a whole that affect and are affected by students' engagement in argumentation. We close the article with implications of this perspective for research, teaching, and instructional design. © 2011 Wiley Periodicals, Inc. J Res Sci Teach 49: 68–94, 2012 相似文献

Informal learning in blended and online settings plays an increasingly important role in the continuous professional development of individuals. Yet, how do individuals engage into these types of activities? We argue that social capital theory can provide valuable insights into how people behave and decide to take part in (in)formal learning. Using social network analysis, we provide empirical evidence on an informal learning activity, where participants collaboratively created knowledge on wiki sites on a predefined set of topics. Our results show that there are three types of active participants in these types of informal learning activities, namely leaders, collaborators and lone editors. These findings provide valuable insights for other, similar activities that aim at enhancing the professional development of individuals. 相似文献

Politics, Markets, and America's Schools is an ambitious book that draws eclectically on concepts from political science, the sociology of organizations and educational learning theory. Chubb and Moe employ an extensive array of data seeking to link the mechanisms that control school operations to student achievement. They conclude that a total restructuring of the governance system of American education — from democratic to market control — is necessary. Our review scrutinizes a set of critical decisions made by Chubb and Moe in defining their key concepts and in the analytical models employed in this research. We argue that many of these decisions are not justified on either theoretical or methodological grounds. Moreover, the cumulative effect of the decision tends to tilt the empirical evidence toward supporting the authors' a priori beliefs. As a result, we conclude that Politics, Markets, and America's Schools is best viewed as a policy argument, where extensive, but not always solid empirical evidence has been artfully employed to advance the authors' preconceived notions about American schooling. 相似文献

While teachers and practitioners are increasingly expected to conduct research on their own practice, there is a lot of educational research that is not directly involved in practice. This often leads to unilateral research perspectives on educational practice. Therefore, this article calls for an alternative model of researching educational practice, summarised through the term ‘pedagogical science’. We argue that practical and normative theories that seek to improve educational practice should be combined with theories that aim to describe and explain. It is further argued that the combination of such perspectives and theories, a so-called stereoscopic point of view, can allow for a thorough and holistic investigation of educational practice. As part of this argumentation, the article addresses critical questions of various theoretical models of educational research, models that are being used in Scandinavian, European and Anglo-American research on educational practice. With reference to interdisciplinary models of educational research, such as educational sciences, learning sciences and Bildungswissenschaften, there are trends in which pedagogy is marginalised. Thus, the second argument of the article calls for placing pedagogy at the centre of knowledge production in a broad sense, after which pedagogy is made into a source of knowledge for pedagogical science, which sets forth to test and provide empirical support for pedagogy-based knowledge. 相似文献

ABSTRACTThis integrative literature review takes up the ongoing discussion about the place of mixed methods designs in educational research. We focus on studies that investigate the role of argumentation in inquiry-based learning, either as a means for enhancing inquiry (argument-based inquiry) or as a learning outcome (inquiry-based argument). We argue that this field of research offers a perfect example of the ways in which a paradigm and its research questions call for mixed-methods designs. We then present an integrative review to explore patterns and identify gaps in the literature, asking: (1) How frequently and in what ways are mixed methods used in the field? (2) What rationales are driving the use of mixed methods? and (3) To what extent is the potential of mixed methods research being realized in the field?. For readers studying argumentation in inquiry-based instruction, we hope to open up a critical dialogue about aims and methodologies in the field. For readers interested in mixed-methods designs we hope to offer a case study of how to build a rationale from within a discipline for leveraging the range of mixed methodologies to study a problem. We conclude with recommendations for further research. 相似文献

Since the late 1990s, there has been consensus among educational researchers that argumentation should play a central role in science education. Although there has been extensive relevant research, it is not clear enough how oral argumentation spontaneously occurs in science teaching. This is particularly important with regard to the empirical evidence suggesting the effect of discussion of contradictory views on scientific learning. In order to contribute to the research on argumentation in science teaching, we conducted a study that aims to sketch a panoramic view of the uses of oral argumentation in Chilean middle-school science teaching. A total of 153 videotaped science lessons were observed, involving students aged 10–11 and 12–13. Whole-class argumentative discourse was analysed as a function of thematic episodes and teachers' and students' utterances. Results suggest that argumentative discourse in which contradictory points of view are discussed is scarce but when it occurs it does so predominantly within discourse among students. On the contrary, argumentation aimed at justifying points of view is widely used, even more so when students are older. 相似文献

In recent years several mathematics education researchers have attempted to analyse students’ arguments using a restricted
form of Toulmin’s [The Uses of Argument, Cambridge University Press, UK, 1958] argumentation scheme. In this paper we report data from task-based interviews conducted with highly talented postgraduate
mathematics students, and argue that a superior categorisation of genuine mathematical argumentation is provided by the use
of Toulmin’s full scheme. In particular, we suggest that modal qualifiers play an important and previously unrecognised role
in mathematical argumentation, and that one of the goals of instruction should be to develop students’ abilities to appropriately
match up warrant-types with modal qualifiers. 相似文献

AbstractInspired by Theodore Schatzki’s ‘societist’ approach—in which he advocates a notion of ‘site ontologies’—in this article, we outline our theory of practice architectures (a theory about what practices are composed of) and ecologies of practices (how practices relate to one another). Drawing on case studies of four Australian primary schools, we examine how practices of leading relate to other educational practices: professional learning, teaching, student learning, and researching and reflecting. We find ‘leading’ not only in the work of principals and other formal leadership positions, but also in the activities of teachers and students. We show that changing leading practices requires changing more than the professional practice knowledge of individuals; it also requires changing the practice architectures (cultural-discursive, material-economic and social-political arrangements) in sites where leading and its interconnected practices are conducted. In order to study practices of leading, we adopt a philosophical-empirical enquiry approach, i.e. we conduct our research as a conversation between practice philosophy and theory and the empirical cases of leading we study. We study practices in the mode of research within practice traditions, sometimes described as ‘practical philosophy’, as a contribution to the self-reflective transformation of the practices we are studying. 相似文献

ABSTRACTStudent engagement in learning science is both a desirable goal and a long-standing teacher challenge. Moving beyond engagement understood as transient topic interest, we argue that cognitive engagement entails sustained interaction in the processes of how knowledge claims are generated, judged, and shared in this subject. In this paper, we particularly focus on the initial claim-building aspect of this reasoning as a crucial phase in student engagement. In reviewing the literature on student reasoning and argumentation, we note that the well-established frameworks for claim-judging are not matched by accounts of creative reasoning in claim-building. We develop an exploratory framework to characterise and enact this reasoning to enhance engagement. We then apply this framework to interpret two lessons by two science teachers where they aimed to develop students’ reasoning capabilities to support learning. 相似文献

AbstractPolicy makers in the UK are trying to improve school meals, by focusing on eating well. This article explores the way policies are framed by academic performance and health as a reason for providing school lunches. Using Nussbaum’s capability approach we argue that the purpose of schooling should be to provide young people with the ability to lead a life of choice. We argue that school meals are an important social good, which allow young people to develop critical skills around food which they can then use throughout their lives. We draw on evidence from two ethnographic research projects on food in schools, conducted in England. We question whether the collocation between healthy eating and learning should be the focus of school food reform and contemplate the role of society and government to provide children with healthy meals, irrespective of learning outcomes. School meals are more than good exam results. 相似文献

There is emerging interest on the interactions between modelling and argumentation in specific contexts, such as genetics learning. It has been suggested that modelling might help students understand and argue on genetics. We propose modelling gene expression as a way to learn molecular genetics and diseases with a genetic component. The study is framed in Tiberghien’s (2000) two worlds of knowledge, the world of “theories & models” and the world of “objects & events”, adding a third component, the world of representations. We seek to examine how modelling and argumentation interact and connect the three worlds of knowledge while modelling gene expression. It is a case study of 10th graders learning about diseases with a genetic component. The research questions are as follows: (1) What argumentative and modelling operations do students enact in the process of modelling gene expression? Specifically, which operations allow connecting the three worlds of knowledge? (2) What are the interactions between modelling and argumentation in modelling gene expression? To what extent do these interactions help students connect the three worlds of knowledge and modelling gene expression? The argumentative operation of using evidence helps students to relate the three worlds of knowledge, enacted in all the connections. It seems to be a relationship among the number of interactions between modelling and argumentation, the connections between world of knowledge and students’ capacity to develop a more sophisticated representation. Despite this is a case study, this approach of analysis reveals potentialities for a deeper understanding of learning genetics though scientific practices. 相似文献

ABSTRACT In this article, we examine the sociopolitical implications of AI technologies as they are integrated into writing instruction and assessment. Drawing from new materialist and Black feminist thought, we consider how learning analytics platforms for writing are animated by and through entanglements of algorithmic reasoning, state standards and assessments, embodied literacy practices, and sociopolitical relations. We do a close reading of research and development documents associated with Essay Helper, a machine learning platform that provides formative feedback on student writing based on standards-aligned rubrics and training data. In particular, we consider the performative acts of the algorithm in the Essay Helper platform – both in the ways that reconstitutes material-discursive relations of difference, and its implications for transactions of teaching and learning. We argue that, through these processes, the algorithms function as racializing assemblages, and conclude by suggesting pathways toward alternative futures that reconfigure the sociopolitical relations the platform inherits. 相似文献

In this article we intend to contribute to the understanding of interest-driven learning which occurs when people find and
choose an interest of their own. This engagement continues over a long time and includes development and learning. The empirical
material consists of 14 learning stories written by experienced and skilled informants in folk dance and different crafts. The purpose is to illuminate the diversity
and complexity of learning and meaning the informants assign to dance or crafts. This is what we consider to be the perspective
of learning by interest. We also argue for the importance of understanding learning by interest as embedded in cultural heritage and social and cultural
changes. Theoretically, we draw on John Dewey (1913/2009; 1934/2005). Learning folk dance or crafts is largely a question of learning by doing, which makes experience important. The interest and effort involved can in our interpretation be understood as experiences where expressions of commitment are embedded. The empirical analysis highlights three emphases in this illumination of the learning process. The first considers
the individual development of skill in relation to broadened learning of collective tasks. The second perspective focuses
on the interplay between learning in a life course and significant learning experiences. The third concerns the interplay
between personal meaning and craftsmanship. In sum, this paper contributes to the understanding of learning by interest as
a useful concept. In the final discussion we expand our perspective since the contrast is obvious between learning by interest
and interpretations of the contemporary society, where individualization and lack of commitment is stressed. 相似文献

This paper focuses on three distinctive ways in which educational software can support learning dialogues in primary classrooms. After a re-capitulation of published research on Initiation, Discussion, Response, Feedback (IDRF) exchanges, where the computer is used to stimulate discussion and then direct it through using feedback, we ask if there are other ways in which educational software and pedagogy can combine to support learning dialogues. We describe the effect of combining preparation for exploratory talk at the computer with group strategy games played against the computer and then we discuss, with examples, the role of software (in this case Bubble Dialogue) that allows groups to externalise their thoughts in order to reflect upon them. We argue that these three types of educational activity exemplify distinctive ways in which the computer enters into and supports educational dialogues. 相似文献

Justification and Persuasion about Cloning: Arguments in Hwang’s Paper and Journalistic Reported Versions 总被引：4，自引：4，他引：0

We examine the argumentative structure of Hwang et al.’s (2004) paper about human somatic cell nuclear transfer (SCNT, or ‘therapeutic cloning’), contrasted with four Journalistic Reported
Versions (JRV) of it, and with students’ summaries of one JRV. As the evaluation of evidence is one of the critical features
of argumentation (Jiménez-Aleixandre 2008), the analysis focuses on the use of evidence, drawing from instruments to analyze written argumentation (Kelly et al. 2008) and from studies about the structure of empirical research reports (Swales 2001). The objectives are: 1) To examine the use of evidence and the argumentative structure of Hwang et al.’s Science, 303: 1669–1674 (2004) original paper in terms of the criteria: a) pertinence of the evidence presented to the claims; b) sufficiency of the evidence
for the purpose of supporting the claims; and c) coordination of the evidence across epistemic levels. 2) To explore how the
structure of Hwang’s paper translates into the JRV and into university students’ perceptions about the evidence supporting
the claims. The argumentative structure of Hwang’s paper is such that its apparently ostensible main claim about NT constitutes
a justification for a second claim about its therapeutic applications, for which no evidence is offered. However, this second
claim receives prominent treatment in the JRV and in the students’ summaries. Implications for promoting critical reading
in the classroom are discussed. 相似文献

Mad City Mystery: Developing Scientific Argumentation Skills with a Place-based Augmented Reality Game on Handheld Computers 总被引：3，自引：5，他引：3
While the knowledge economy has reshaped the world, schools lag behind in producing appropriate learning for this social change.
Science education needs to prepare students for a future world in which multiple representations are the norm and adults are
required to “think like scientists.” Location-based augmented reality games offer an opportunity to create a “post-progressive”
pedagogy in which students are not only immersed in authentic scientific inquiry, but also required to perform in adult scientific
discourses. This cross-case comparison as a component of a design-based research study investigates three cases (roughly 28
students total) where an Augmented Reality curriculum, Mad City Mystery, was used to support learning in environmental science.
We investigate whether augmented reality games on handhelds can be used to engage students in scientific thinking (particularly
argumentation), how game structures affect students’ thinking, the impact of role playing on learning, and the role of the
physical environment in shaping learning. We argue that such games hold potential for engaging students in meaningful scientific
argumentation. Through game play, players are required to develop narrative accounts of scientific phenomena, a process that
requires them to develop and argue scientific explanations. We argue that specific game features scaffold this thinking process,
creating supports for student thinking non-existent in most inquiry-based learning environments. 相似文献
