Teachers are central to providing high-quality science learning experiences called for in recent reform efforts, as their understanding of science impacts both what they teach and how they teach it. Yet, most elementary teachers do not enter the profession with a particular interest in science or expertise in science teaching. Research also indicates elementary schools present unique barriers that may inhibit science teaching. This case study utilizes the framework of identity to explore how one elementary classroom teacher’s understandings of herself as a science specialist were shaped by the bilingual elementary school context as she planned for and provided reform-based science instruction. Utilizing Gee’s (2000) sociocultural framework, identity was defined as consisting of four interrelated dimensions that served as analytic frames for examining how this teacher understood her new role through social positioning within her school. Findings describe the ways in which this teacher’s identity as a science teacher was influenced by the school context. The case study reveals two important implications for teacher identity. First, collaboration for science teaching is essential for elementary teachers to change their practice. It can be challenging for teachers to form an identity as a science teacher in isolation. In addition, elementary teachers new to science teaching negotiate their emerging science practice with their prior experiences and the school context. For example, in the context of a bilingual school, this teacher adapted the reform-based science curriculum to better meet the unique linguistic needs of her students.

Understanding the interaction between internally constructed and externally imposed aspects of the teaching context may be the missing link between calls for school reform and teachers' interpretation and implementation of that reform. Although the context of the local school culture has a profound impact on teachers, there are other external forces that are specifically aimed at influencing teachers' pedagogical and curricular decisions. These externally imposed aspects of context include some of the existing tools of reform, such as national standards, mandated state core curricula, and related criterion‐referenced testing. However, little is known about how these reform tools impact teachers' thinking about science and science teaching or how teachers respond to such tools. This study examined the interactions between individual teachers' beliefs about teaching and learning science in elementary school and the tools of reform that are imposed upon them. Comparative case studies were conducted in which two elementary teachers' science instruction, teaching context, and related beliefs were examined, described, and analyzed. In this study, the teachers' fundamental beliefs about science and what it means to teach and learn science influenced their interpretations of the sometimes contradictory messages of reform as they are represented in the standards, mandated curriculum, and end‐of‐level tests. Suggestions about what these findings mean for needed aspects of teacher professional development are offered. © 2007 Wiley Periodicals, Inc. J Res Sci Teach 44: 396–423, 2007 相似文献

The purpose of this research was to understand how preservice elementary teacher experiences within the context of reflective science teacher education influence the development of professional knowledge. We conducted a case analysis to investigate one preservice teacher's beliefs about science teaching and learning, identify the tensions with which she grappled in learning to teach elementary science, understand the frames from which she identified problems of practice, and discern how her experiences played a role in framing and reframing problems of practice. The teacher, Barbara, encountered tensions in thinking about science teaching and learning as a result of inconsistencies between her vision of science teaching and her practice. Confronting these tensions between ideals and realities prompted Barbara to rethink the connections between her classroom actions and students' learning and create new perspectives for viewing her practice. Through reframing, she was able to consider and begin implementing alternative practices more resonant with her beliefs. Barbara's case illustrates the value of understanding prospective teachers' beliefs, their experiences, and the relationship between beliefs and classroom actions. Furthermore, the findings underscore the significance of offering reflective experience as professionals early in the careers of prospective teachers. © 1999 John Wiley & Sons, Inc.

This case study describes what happened when two lead teachers in a statewide reform project tried to change science teaching in their schools. Instead of using traditional criteria for leadership, we view their work in the context of their schools' cultures and use Rosenholtz's (1991) concepts of egalitarianism and isolation to analyze how those cultures contributed to and obstructed reform. Five themes illustrate this model of teacher leadership and the first stirrings of school change: reform as a “science look,” change through parental involvement, competing reforms, change through a “sideways door,” and change through public events. The study shows the importance of patience in reform implementation and the need for sensitive study of early change within school contexts. © 1998 John Wiley & Sons, Inc.

Much of teacher knowledge research in teacher education has focused on Western views of teacher knowledge. By reporting on a case study of an immigrant Chinese language teacher's personal practical knowledge in teaching secondary school students, this paper presents an Eastern view of teacher knowledge, and illustrates how knowledge and identity are entwined. The study found that an immigrant teacher's awareness of her identity and her cultural heritage had a profound influence on shaping her personal practical knowledge and teaching practice. The paper suggests that more cross-cultural studies be undertaken to further our understanding of teacher knowledge. 相似文献

In this paper I discuss how reform in science education is interpreted by Barma as she recounts the story of Catherine, a grade 9 biology teacher, who reforms her teaching practices in response to a national curriculum reform in Quebec, Canada. Unlike some cases in response to reform, this case is hopeful and positive. Also in this paper, I address some familiar areas that must be considered when teachers undertake curriculum reform and how science educators may fulfill the role of facilitator and advocate in the support of teachers on the road to reform. The commentary focuses on how Barma retells the story through the lens of activity theory. 相似文献

In this paper, we report a case study of a 16-year-old Swedish upper secondary student's developing understanding of key concept areas studied in his upper secondary school chemistry course. This study illustrates how the thinking of an individual learner, Jesper, evolves over a school year in response to formal instruction in a particular educational context. Jesper presented a range of ideas, some of which matched intended teaching whilst others were quite inconsistent with canonical chemistry. Of particular interest, research data suggest that his initial alternative conceptions influenced his thinking about subsequent teaching of chemistry subject matter, illustrating how students' alternative conceptions interact with formal instruction. Our findings support the claims of some researchers that alternative conceptions may be stable and tenacious in the context of instruction. Jesper's rich conceptualisation of matter at submicroscopic scales drew upon intuitions about the world that led to teaching being misinterpreted to develop further alternative conceptions. Yet his intuitive thinking also offered clear potential links with canonical scientific concepts that could have been harnessed to channel his developing thinking. These findings support the argument that identifying students' intuitive thinking and how it develops in different instructional contexts can support the development of more effective science pedagogy. 相似文献

This study unveils the stories of 3 public school elementary teachers from the USA who reflected on their beliefs about science education reform, and implementation of the reform in their classroom teaching, in response to state recommendations for change in science education. The teachers' stories show how various factors assisted or impeded the implementations of reform in their teaching, the various challenges related to their grade-level teaching, and the teachers' personal struggles to make sense of reform recommendations. Within each case study, we describe 4 common themes from the teachers' interviews. These themes are related to teachers' science teaching strategies, their science teaching efficacy beliefs about adopting reform, the types of science learning outcomes teachers target, and the types of teaching resources available to them. Implications for teacher education and practice are discussed in relationship with study findings. 相似文献

This article is a case study of a second-year middle school science teacher's beliefs about science and science teaching and how these beliefs influenced—or failed to influence—classroom instruction. It illustrates how beginning teachers struggle to reconcile (a) conflicting beliefs about what is desirable, and (b) conflicts between what they believe is desirable and what is possible within the constraints of their preparation and the institutions in which they work. This teacher, for example, struggled to reconcile his view of science as a creative endeavor with his belief that students need to be provided with a high degree of structure in order to learn within the context of formal schooling. He also had difficulty resolving the conflict between the informal (“messing about”) type of science learning that he believed was desirable and the personal and institutional constraints he faced in the classroom. 相似文献

A teacher's orientation toward science teaching has been proposed as very influential to a teacher's pedagogical content knowledge (PCK) and teaching practice. Experienced teachers' orientation toward science teaching and its connections to their practice has not been well explored. Focusing on a unit about the periodic table, this study provides a case study using a respected, experienced high-school chemistry teacher's orientation toward science teaching to make sense of her observed teaching practice. Aspects of her practice, which aligned and misaligned with current recommendations for science teaching, were explored. Using observations, interviews, and class documents, the study concluded that the teacher's orientation toward science teaching was an appropriate way of understanding her teaching practice. While also being shown to be a useful tool for researchers, this case provides an example how a teacher's orientation toward science teaching could help in the development of professional development, specifically professional development for the recently released Next Generation Science Standards. 相似文献

Concern is increasingly being expressed about the teaching of higher order thinking skills in schools and the levels of understanding
of scientific concepts by students. Metaphors for the improvement of science education have included science as exploration
and science as process skills for experimentation. As a result of a series of studies on how children relate evidence to their
theories or beliefs, Kuhn (1993a) has suggested that changing the metaphor to science as argument may be a fruitful way to
increase the development of higher order thinking skills and understanding in science instruction. This report is of a case
study into the coordination of evidence and theories by a grade 7 primary school student. This student was not able to coordinate
these elements in a way that would enable her to rationally consider evidence in relation to her theories. It appeared that
the thinking skills associated with science as argument were similar for her in different domains of knowledge and context.

This article reports on a three‐year ethnographic study with an experienced elementary science teacher and describes the role of her positive and negative emotions in constructing her science pedagogy, curriculum planning, and relationships with children and colleagues. Examples are offered of the different emotional experiences she related to her science teaching, and it is shown how insights from this research are useful and significant to researchers and educators who want to improve science teaching and learning. A conceptual and methodological framework developed by the author that is based on an interdisciplinary approach in researching emotions is presented. Finally, some implications of researching emotions for elementary science teacher education and science education reform are suggested. © 2002 John Wiley & Sons, Inc.

Conclusion The impact of Pestalozzian theory as embodied in object teaching was only significantly felt in America when teacher-education
institutions began teaching the spirit and techniques of this method. Sheldon and his colleagues helped spread object teaching
across America by utilizing inservice teacher education, preservice teacher education, a Practice School, and education of
teacher educators. This enlightenment in education shifted the instructional focus to the child, stressing activity and concrete
experiences, rather than dull rote memorization. Elementary school science evolved from object teaching, and methods of science
instruction were influenced by the object teaching movement. Educational reform may never again occur as swiftly or as dramatically;
however, the message is clear: Significant, meaningful changecan occur in schools through teacher education. 相似文献

An urgent goal for science teacher educators is to prepare teachers to teach science in meaningful ways to youth from nondominant
backgrounds. This preparation is challenging, for it asks teachers to critically examine how their pedagogical practices might
adaptively respond to students and to science. It asks, essentially, for new teachers to become researchers of their own beginning
practice. This study explores the story of Ben as he coauthored a transformative action research project in an urban middle
school as part of a teacher education program and, later, over his first year of teaching at that same school. We describe
how Ben and his partner teacher created innovative spaces for science learning. This offered Ben an opportunity to make some
of his deeply engrained pedagogical beliefs come alive within a context of distributed expertise, which provided for him a
space of moderate risk where he could afford the chances of failure without undermining how he felt about his own capacity
as a teacher. Our study highlights the importance of creating reform opportunities within the context of teacher education
programs that may help beginner teachers construct positive images of teaching that they can hold on to in their future practice. 相似文献

Inquiry in interaction: How local adaptations of curricula shape classroom communities 总被引：1，自引：0，他引：1
In this study, we seek a better understanding of how individuals and their daily interactions shape and reshape social structures that constitute a classroom community. Moreover, we provide insight into how discourse and classroom interactions shape the nature of a learning community, as well as which aspects of the classroom culture may be consequential for learning. The participants in this study include two teachers who are implementing a new environmental science program, Global Learning through Observation to Benefit the Environment (GLOBE), and interacting with 54 children in an urban middle school. Both qualitative and quantitative data are analyzed and presented. To gain a better understanding of the inquiry teaching within classroom communities, we compare and contrast the discourse and interactions of the two teachers during three parallel environmental science lessons. The focus of our analysis includes (1) how the community identifies the object or goal of its activity; and (2) how the rights, rules, and roles for members are established and inhabited in interaction. Quantitative analyses of student pre‐ and posttests suggest greater learning for students in one classroom over the other, providing support for the influence of the classroom community and interactional choices of the teacher on student learning. Implications of the findings from this study are discussed in the context of curricular design, professional development, and educational reform. ? 2004 Wiley Periodicals, Inc.

This study examines the self-efficacy of one preservice elementary school teacher (Kasey) during and after her participation
in Science in Childhood Education—a 16-week, elementary preservice science methods course. The case study of this teacher
is situated in the context of the class as a whole. This is accomplished through interviewing the one teacher and examining
artifacts and observations of the entire class. The results of these experiences are studied to determine what changes have
taken place in the participants’ self-efficacy in science teaching as well as the one preservice teacher in greater detail.
Because self efficacy is influential to student learning, the results of this study have significant implications for the
design of elementary teacher education programs and the support of elementary teachers in teaching science. 相似文献

Using the insights of the French sociologist, Pierre Bourdieu, this article considers the role of the science department chair in the reform of school science education. Using Bourdieu’s ‘thinking tools’ of ‘field’, ‘habitus’ and ‘capital’, we case study the work of two teachers who both actively pursue the teaching and learning of science as inquiry. One teacher, Dan, has been a department chair since 2000, and has actively encouraged his department to embrace science as inquiry. The other teacher, Leslie, worked for one year in Dan’s department before being transferred to another school where science teaching continues to be more traditional. Our work suggests that there are three crucial considerations for chairs seeking to lead the reform of science teaching within their department. The first of these is the development of a reform-minded habitus, as this appears to be foundational to the capital that can be expended in the leadership of reform. The second is an understanding of how to wield power and position in the promotion of reform. The third is the capacity to operate simultaneously and strategically within, and across, two fields; the departmental field and the larger science education field. This involves downplaying administrative logics, and foregrounding more inquiry-focused logics as a vehicle to challenge traditional science-teaching dispositions—the latter being typically dominated by concerns about curriculum ‘coverage’. 相似文献

Constructivism is a set of beliefs that can be used by teachers to think about learning and teaching and to plan and enact
a science curriculum. This paper is a fictional account of an elementary science teacher and her use of constructivism as
a referent for her various roles as a science teacher. The paper also describes how the teacher came to teach in this manner,
describing her involvement in staff development activities and an evolution in her thinking from an ojectivist to a constructivist
system of semantics. Implications are presented for the reform of science education. 相似文献
