Through the examination of the experiences of a pre-service teacher participating in a field-based science methods course,
we make evident the ways in which a combination of collaborative teaching experiences and reflexive dialogues allowed for
the evolution and transformation of her identity. This teacher is Johaira Lara, the second author of this paper, and we have
engaged in a cowriting approach that has created layers of writings over time, with the focus of providing evidence of her
changing perceptions and understandings of teaching and learning science. We describe the ways coteaching and cogenerative
dialogues provided the opportunity for Johaira to examine and reconsider her views on science teaching, and mediated the production
and transformation of her identity. We offer an evolving analysis of her identity transformation related to specific aspects
of the course that were pivotal for her emergence as an elementary teacher of science. 相似文献

This study examines the transformation and dynamic nature of one teacher candidate’s (Susan) identity as a learner and teacher of science throughout an innovative science methods course. The goal of this paper is to use theoretically derived themes grounded in cultural-historical activity theory (CHAT) and situated learning theory to determine the ways in which Susan’s identity as a learner and teacher of science was influenced by her experiences in the course, and to describe how she made meaning of her transformative process. The following are the three theoretical themes: (1) learning contributes to identity development, (2) identity development is a dialogical process that occurs between individuals, not within individuals, and (3) social practice leads to transformations and transformations lead to the creation of new social practices. Within each theme, specific experiences in the science methods course are identified that influenced Susan’s identity development as a teacher of science. Knowing how context and experiences influence identity development can inform design decisions concerning teacher education programs, courses, and experiences for candidates. 相似文献

This qualitative case study looks closely at an elementary teacher who participated in professional development experiences that helped her develop a hybrid practice of using inquiry-based science to teach both science content and English language development (ELD) to her students, many of whom are English language learners (ELLs). This case study examines the teacher’s reflections on her teaching and her students’ learning as she engaged her students in science learning and supported their developing language skills. It explicates the professional learning experiences that supported the development of this hybrid practice. Closely examining the pedagogical practice and reflections of a teacher who is developing an inquiry-based approach to both science learning and language development can provide insights into how teachers come to integrate their professional development experiences with their classroom expertise in order to create a hybrid inquiry-based science ELD practice. This qualitative case study contributes to the emerging scholarship on the development of teacher practice of inquiry-based science instruction as a vehicle for both science instruction and ELD for ELLs. This study demonstrates how an effective teaching practice that supports both the science and language learning of students can develop from ongoing professional learning experiences that are grounded in current perspectives about language development and that immerse teachers in an inquiry-based approach to learning and instruction. Additionally, this case study also underscores the important role that professional learning opportunities can play in supporting teachers in developing a deeper understanding of the affordances that inquiry-based science can provide for language development. 相似文献

This paper reports how a teacher–researcher partnership examined a biology teacher's existing pedagogical practices and attempted, through a task design innovation, to create the circumstances under which more interactive and emergent assessment for learning practices could flourish in her classroom. This work involved the use of digital video playback technology as the trigger or catalyst for reflection on concrete experiences by the teacher and her students to occur. Results suggest that the digital video innovation brought about changes in student–teacher interactions in science practical work and assisted the teacher in reflecting on her professional learning. The educative effects produced by the catalyst were dependent on the teacher noticing changes in her students and moving in tandem with them along a parallel path of experiential and practitioner-based learning. Overall, the value of the study undertaken is located in sharing an authentic, lived science assessment experience with the intention of assisting colleagues notice aspects of their own pedagogic practices that may be hidden at present. 相似文献

This study is an interpretive investigation of Sarah, a first-time teacher of middle- and high-school science who, because of high levels of disruption, was unable to establish and maintain environments favorable to learning. Sarah reflected on her roles as a teacher and identified facilitating learning, management, and assessment as salient, each being associated with defining metaphors and belief sets. Sarah's efforts to improve her teaching began with the construction of a new metaphor, the social director, for her role as manager. She developed coherence between the new metaphor and beliefs about constructivism, teaching, and learning. Sarah then managed her class in accordance with the social director metaphor and, although improvements were apparent, some students were uncooperative. Sarah then changed her metaphor for assessment from the teacher being a fair judge to the teacher looking through a window into a student's mind, an opportunity for students to show what is known. When this metaphor guided Sarah's assessment practices the learning environment improved appreciably. Although the development of new metaphors was a significant part of the process of reconceptualizing her roles as a science teacher, Sarah could not have improved the quality of teaching and learning without substantial assistance from her colleagues and school administrators. 相似文献

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.

One of the central challenges globalization and immigration present to education is how to construct school language policies,
procedures, and curricula to support academic success of immigrant youth. This case-study compares and contrasts language
experience narratives along Elena’s developmental trajectory of becoming an urban science teacher. Elena reflects upon her
early language experiences and her more recent experiences as a preservice science teacher in elementary dual language classrooms.
The findings from Elena’s early schooling experiences provide an analysis of the linkages between Elena’s developing English
proficiency, her Spanish proficiency, and her autobiographical reasoning. Elena’s experiences as a preservice teacher in two
elementary dual language classrooms indicates ways in which those experiences helped to reframe her views about the intersections
between language learning and science learning. I propose the language experience narrative, as a subset of the life story,
as a way to understand how preservice teachers reconstruct past language experiences, connect to the present, and anticipate
future language practices. 相似文献

Enquiry-based science in primary classrooms is key to encouraging children's interest and curiosity about the world around them and as a result helps to stimulate their understanding and enjoyment of science. Yet many primary teachers lack the confidence to implement enquiry-based approaches effectively. The reasons are myriad and often result in the teacher controlling and orchestrating the lesson leaving little room for children's exploration and autonomy. This paper explores how one infant school teacher was willing to relinquish control and ‘let go’ and expand her pedagogical repertoire to manage the many obstacles to including enquiry-based science in her classroom. The autonomy the children were given resulted in genuine enquiry-based science with the consequential benefit to their learning. Furthermore the teacher's confidence and self-efficacy seem to have been raised ensuring that that she would continue to include enquiry-based science as part of her practice in the future. As a model for other primary teachers this approach could help them overcome their reticence to engage with enquiry-based science. 相似文献

In this paper, we offer illustrations of a mathematics teacher’s difficulties with content knowledge when trying to find connections between school mathematics and science; we do so by describing the development of this teacher’s thinking and learning in her pursuit of connections between the concepts of slope of a line and density of matter. The paper is based on a sub-study that is part of a larger Colombian project, PROMESA (Creating Science and Mathematics Connected Learning Experiences that Open Opportunities for the Promotion of Algebraic Reasoning), which incorporated a Professional Learning Programme (PLP) seeking to integrate school science and mathematics teachers into working teams, in order to create science and mathematics connected learning experiences that considered the promotion of algebraic reasoning. The ‘challenging questions’ that emerged for this teacher, during the workshops of the induction stage of the PLP, became the driving force for her continued engagement in learning mathematics content in a connected way, as opposed to the compartmentalised content-item thinking that she had experienced as a school student. We provide illustrations of first steps in the development of a teacher’s mathematical understanding, which can support growth of mathematical knowledge for teaching. 相似文献

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.

The purpose of this paper is to identify tensions in teacher–student interaction in a high school biology laboratory. Using micro‐analytic analysis of classroom talk, the interaction between the students and a teacher working in the biology laboratory session on Reproduction in Plants is studied. The two tensions highlighted here are tension with textbooks as authority and tension with the teacher as authority. Tension with textbooks as authority originates from an over‐reliance on generalizations expressed in textbooks resulting in the inability of learners to appreciate alternatives and exceptions. Tension with the teacher as authority stems from the task design and varying levels of control that a teacher has over the learner and the learning process. The genesis of the two forms of tensions in the laboratory is different and they are tackled differently by the participants to yield different outcomes. While science educators have conducted intensive research over the past two decades on the effects of school science laboratory work on students’ learning of science, more can be done in the specific area of teacher–student interaction. This paper offers some insights into the interaction between a teacher and her students in a laboratory as they learn biology. An increased understanding of the impact of the tensions in a science laboratory might help to bring about realization of the true spirit and intent of school science laboratory experiences. 相似文献

A case study of an exemplary third grade teacher??s use of the outdoor classroom for meeting both state science and language arts standards is described. Data from the researcher??s field journal, teacher lesson plans, and teacher interviews document how this teacher used nature-study to bridge outdoor classroom experiences with the state science and language arts curriculum. This teacher??s early life experiences supported her strong interest in science and nature in the outdoors and experiencing it with her children. Children interacted with the outdoor classroom throughout the day as a context for science and literacy learning. All but one child successfully met Annual Yearly Progress (AYP) goals in reading at the end of the school year. 相似文献

Pedagogical content knowledge (PCK) is a much debated and studied construct. In this article, we adopt an all‐embracing view of PCK to examine the development of one elementary science teacher's knowledge over a 10‐year period. We portray this teacher's knowledge at three critical points in her career—as a student teacher, beginning teacher, and established teacher—and represent and analyze the growth of her science PCK using the metaphor of a knowledge tree. The tree metaphor shows that while science knowledge begins as the major branch of science PCK, it is soon overshadowed by the general teaching and interactive knowledge branches of science PCK; however, taken together, all three branches contribute over time to the formation of a healthy, established tree of science PCK. © 2005 Wiley Periodicals, Inc.

An in-depth study of a teacher engaged in an innovative primary science trial professional development project 总被引：2，自引：1，他引：2
The implementation of effective science programmes in primary schools is of continuing interest and concern for professional
developers. As part of the Australian Academy of science's approach to creating an awareness ofPrimary Investigations, a project team trialed a series of satellite television broadcasts of lessons related to two units of the curriculum for
Year 3 and 4 children in 48 participating schools. The professional development project entitledSimply Science, included a focused component for the respective classroom teachers, which was also conducted by satellite. This paper reports
the involvement of a Year 4 teacher in the project and describes her professional growth. Already an experienced and confident
teacher, no quantitative changes in science teaching self efficacy were detected. However, her pedagogical content knowledge
and confidence to teach science in the concept areas of matter and energy were enhanced. Changes in the teacher's views about
the co-operative learning strategies espoused byPrimary Investigations were also evident. Implications for the design of professional development programmes for primary science teachers are discussed. 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.

The interactions of a primary school teacher with her class during two sessions of science are analysed to find the extent to which the teacher can be considered to be assisting the performance of her class. The qualitative analysis is in terms of both Tharp and Gallimore's six assisting behaviours and Coulthard's 'initiation-response-feedback' pattern for typical classroom discourse. The teaching shows features which suggest children's science concepts are being developed and features which are consistent with assisted performance, though it is not possible to show a causal relationship between these two aspects. It is suggested that there would be potential for exploring assisted performance further as a framework for teaching for conceptual development in primary science. 相似文献

Learning to look through the eyes of our students: action research as a tool of inquiry 总被引：1，自引：1，他引：0
Abstract The story we are about to tell occurred when Gayle was a middle school science teacher and graduate student in Joanne's seminar on the study of teaching. Gayle was trying to make sense of her science students' indifference toward the environment, an attitude that concerned her as an environmentalist. She turned her inquiry into an action research project that sought to answer the question, ‘What are the assumptions that my middle school students have about their relationship with the environment?’ Joanne was mentoring Gayle in her action research study, and at the same time exploring Gayle's perspective as an action researcher. Now, several years later, we are both action researchers and teacher educators and understand that we have been looking through the eyes of our students in order to become scholars of our own teaching. 相似文献

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
