This study examined the knowledge, beliefs and efforts of five prospective teachers to enact teaching science as inquiry, over the course of a one‐year high school fieldwork experience. Data sources included interviews, field notes, and artifacts, as these prospective teachers engaged in learning how to teach science. Research questions included 1) What were these prospective teachers' beliefs of teaching science? 2) To what extent did these prospective teachers articulate understandings of teaching science as inquiry? 3) In what ways, if any, did these prospective teachers endeavor to teach science as inquiry in their classrooms? 4) In what ways did the mentor teachers' views of teaching science appear to support or constrain these prospective teachers' intentions and abilities to teach science as inquiry? Despite support from a professional development school setting, the Interns' teaching strategies represented an entire spectrum of practice—from traditional, lecture‐driven lessons, to innovative, open, full‐inquiry projects. Evidence suggests one of the critical factors influencing a prospective teacher's intentions and abilities to teach science as inquiry, is the teacher's complex set of personal beliefs about teaching and of science. This paper explores the methodological issues in examining teachers' beliefs and knowledge in actual classroom practice. © 2007 Wiley Periodicals, Inc. J Res Sci Teach 44: 613–642, 2007. 相似文献

The world over, secondary school science is viewed mainly as a practical subject. This may be one reason why effectiveness of teaching approaches in science education has often been judged on the kinds of practical activity with which teachers and students engage. In addition to practical work, language??often written (as in science texts) or oral (as in the form of teacher and student talk)??is unavoidable in effective teaching and learning of science. Generally however, the role of (instructional) language in quality of learning of school science has remained out of focus in science education research. This has been in spite of findings in empirical research on difficulties science students encounter with words of the instructional language used in science. The findings have suggested that use of (instructional) language in science texts and classrooms can be a major influence on the level of students?? understandings and retention of science concepts. This article reports and discusses findings in an investigation of physics teachers?? approaches to use of and their beliefs about classroom instructional language. Direct classroom observations of, interviews with, as well as content analyses of the participant teachers?? verbatim classroom talk, were used as the methods of data collection. Evidence is presented of participant physics teachers?? lack of explicit awareness of the difficulty, nature, and functional value of different categories of words in the instructional language. In conclusion, the implications of this lack of explicit awareness on the general education (initial and in-service) of school physics teachers are considered. 相似文献

What are the barriers to technology‐rich inquiry pedagogy in urban science classrooms, and what kinds of programs and support structures allow these barriers to be overcome? Research on the pedagogical practices within urban classrooms suggests that as a result of many constraints, many urban teachers' practices emphasize directive, controlling teaching, that is, the “pedagogy of poverty” (Haberman, 1991 ), rather than the facilitation of students' ownership and control over their learning, as advocated in inquiry science. On balance, research programs that advocate standards‐based or inquiry teaching pedagogies demonstrate strong learning outcomes by urban students. This study tracked classroom research on a technology‐rich inquiry weather program with six urban science teachers. The teachers implemented this program in coordination with a district‐wide middle school science reform. Results indicated that despite many challenges in the first year of implementation, students in all 19 classrooms of this program demonstrated significant content and inquiry gains. In addition, case study data comprised of twice‐weekly classroom observations and interviews with the six teachers suggest support structures that were both conducive and challenging to inquiry pedagogy. Our work has extended previous studies on urban science pedagogy and practices as it has begun to articulate what role the technological component plays either in contributing to the challenges we experienced or in helping urban science classrooms to realize inquiry science and other positive learning values. Although these data outline results after only the first year of systemic reform, we suggest that they begin to build evidence for the role of technology‐rich inquiry programs in combating the pedagogy of poverty in urban science classrooms. © 2002 John Wiley & Sons, Inc.

This study explored how preservice teachers grew in their understanding of inquiry science through conducting an in-depth
individual inquiry investigation in their science methods course. Elementary preservice teachers’ understanding about inquiry
investigations, their attitudes towards the assignment, and their views towards using individual inquiry investigations in
their own classrooms were studied through written reflections, science notebook writings, and researcher field notes. After
conducting an out-of-class inquiry investigation based on their own questions and design, the preservice teachers demonstrated
a variety of strengths in their understandings of inquiry-based teaching, their attitudes towards doing science, and their
projected use of inquiry in their own classrooms. Weak areas included forming researchable questions and superficial experimental
design. 相似文献

This article is concerned with the personal constructs of science teachers about inquiry in selected schools in the Yorkshire and the Humber region of England. While there is a large volume of existing literature which advocates the use of inquiry in the science classroom to enhance students' engagement with, and learning of science, relatively few of these studies represent teachers' voice. Therefore, we believe that it is important and distinctive to report teachers' constructs of inquiry and related concerns regarding its use in the science classroom. We identify the key constructs from 10 participating teachers and discuss these amongst a backdrop of policy implications for inquiry approaches in English secondary school science classrooms. Personal Construct Theory was used to underpin the study and frame data collection and analysis. Key findings show that the teachers identify an inquiry approach as being effective in stimulating students' independent learning and interest in science but issues such as time and confidence inhibit their deployment of inquiry approaches. 相似文献

In this paper, we characterize the inquiry practices of four elementary school teachers by means of a pedagogical framework.
Our study revealed core components of inquiry found in theoretically-driven models as well as practices that were regarded
as integral to the success of day-to-day science teaching in Singapore. This approach towards describing actual science inquiry
practices—a surprisingly neglected area—uncovered nuances in teacher instructions that can impact inquiry-based lessons as
well as contribute to a practice-oriented perspective of science teaching. In particular, we found that these teachers attached
importance to (a) preparing students for investigations, both cognitively and procedurally; (b) iterating pedagogical components
where helping students understand and construct concepts did not follow a planned linear path but involved continuous monitoring
of learning; and (c) synthesizing concepts in a consolidation phase. Our findings underscore the dialectical relationship
between practice-oriented knowledge and theoretical conceptions of teaching/learning thereby helping educators better appreciate
how teachers adapt inquiry science for different contexts. 相似文献

A group of teachers?? meaning-making when they are collaboratively analyzing artifacts from practice in local science classrooms in a school-based professional development (PD) project is examined through repeated interviews and represented as meaning-making maps. The interpretation of the teachers?? meaning-making includes both their reference to outcomes from the project and their expressed ideas about teaching and learning of science. All four teachers refer to experiences from experimenting in their classrooms and interpret the collected artifacts in relation to students?? learning. Furthermore, they all felt encouraged to continue collaboration around science. During the interviews, the teachers emphasize various elements apparently connected to concrete challenges they each experience in their professional work. Implications in relation to the design of PD are discussed. 相似文献

In this study, a wiki was integrated into a professional development model that systemically addresses early-career teachers?? needs. This study was conducted to examine the impact of wiki-based professional development activities in a scientist-teacher professional learning community and focused on early-career teachers?? perceptions of the role of wiki technology and knowledge of teaching through inquiry. Teachers participated in the Professional Learning Community Model for Entry into Teaching Science (PLC-METS), a professional development program that is based on an integrated teacher education model of knowledge sharing, collaboration, and communication between teachers and scientists, with the goal of supporting early-career teachers?? ability to engage their students in scientific inquiry. The use of a wiki environment to collaborate on activities, deliver resources, and share knowledge is rapidly expanding in professional development communities. The use of the wiki in PLC-METS positively predicted the results of teachers?? knowledge of inquiry-based teaching. Results demonstrate that the wiki can contribute to building a learning community for collaboration between early-career science teachers and scientists. The paper also discusses the educational implications for the design of wiki-based professional learning communities that impact teachers?? professional development. 相似文献

In this paper I examine the phenomenon of university teachers as researchers in their own classrooms. I use examples of three
research teams in which we studied: (1) student response to a science and society course; (2) teacher and student perceptions
of inquiry in a physics course; and (3) teaching and learning about the nature of science in an elementary science pedagogy
course. In addition to describing each study, I compare their purposes, researcher roles, and actions taken. I use these comparisons
to address the ideological clashes and dilemmas of ownership, action, and quality that arise in this kind of research. Finally,
I comment upon the significance of university teachers as researchers for themselves, their institutions, and the research
community. 相似文献

Preservice science teachers face numerous challenges in understanding and teaching science as inquiry. Over the course of their teacher education program, they are expected to move from veteran science students with little experience learning their discipline through inquiry instruction to beginning science teachers adept at implementing inquiry in their own classrooms. In this study, we used Aikenhead’s (Sci Educ 81: 217–238, 1997, Science Educ 85:180–188, 2001) notion of border crossing to describe this transition preservice teachers must make from science student to science teacher. We examined what one cohort of eight preservice secondary science teachers said, did, and wrote as they both conducted a two-part inquiry investigation and designed an inquiry lesson plan. We conducted two types of qualitative analyses. One, we drew from Costa (Sci Educ 79: 313–333, 1995) to group our preservice teacher participants into one of four types of potential science teachers. Two, we identified successes and struggles in preservice teachers’ attempts to negotiate the cultural border between veteran student and beginning teacher. In our implications, we argue that preservice teachers could benefit from explicit opportunities to navigate the border between learning and teaching science; such opportunities could deepen their conceptions of inquiry beyond those exclusively fashioned as either student or teacher. 相似文献

In this study, we present the long-term influence of an after school science practicum associated with an elementary science methods course. The practicum or field experience could be considered a community-based service learning programme as it is situated both within and for the community. Study participants included eight third- and fifth-grade teachers who had participated in elementary science methods courses; four of these teachers participated in the after school teaching practicum while four participants experienced a more traditional observation-based elementary science practicum. All of these teachers were in their second or third year teaching which was 3–4 years after taking the methods course. Investigation methods included questionnaires, field observations and semi-structured, individual interviews. Teachers more regularly utilised reform-based teaching strategies and cited the after school teaching practicum as preparing them to use these strategies in their own classrooms. All teachers exhibited a growth mindset to some degree, but the after school practicum participants did demonstrate a wider use of reformed-based teaching strategies and a higher growth mindset. Elementary teachers perceive risk associated with these key aspects of instruction: (1) managing instruction and classroom management, (2) teaching science through guided inquiry, and (3) overcoming adoptions in other ‘mandated’ curriculum like math and reading. 相似文献

This investigation examined 10th‐grade biology students' decisions to enroll in elective science courses, and explored certain attitudinal perceptions of students that may be related to such decisions. The student science perceptions were focused on student and classroom attitudes in the context of differing learning cycle classrooms (high paradigmatic/high inquiry, and low paradigmatic/low inquiry). The study also examined possible differences in enrollment decisions/intentions and attitudinal perceptions among males and females in these course contexts. The specific purposes were to: (a) explore possible differences in students' decisions, and in male and female students' decisions to enroll in elective science courses in high versus low paradigmatic learning cycle classrooms; (b) describe patterns and examine possible differences in male and female students' attitudinal perceptions of science in the two course contexts; (c) investigate possible differences in students' science perceptions according to their decisions to enroll in elective science courses, participation in high versus low paradigmatic learning cycle classrooms, and the interaction between these two variables; and (d) examine students' explanations of their decisions to enroll or not enroll in elective science courses. Questionnaire and observation data were collected from 119 students in the classrooms of six learning cycle biology teachers. Results indicated that in classrooms where teachers most closely adhered to the ideal learning cycle, students had more positive attitudes than those in classrooms where teachers deviated from the ideal model. Significantly more females in high paradigmatic learning cycle classrooms planned to continue taking science course work compared with females in low paradigmatic learning cycle classrooms. Male students in low paradigmatic learning cycle classrooms had more negative perceptions of science compared with males in high paradigmatic classrooms, and in some cases, with all female students. It appears that using the model as it was originally designed may lead to more positive attitudes and persistence in science among students. Implications include the need for science educators to help teachers gain more thorough understanding of the learning cycle and its theoretical underpinnings so they may better implement this procedure in classroom teaching. © 2001 John Wiley & Sons, Inc.

Marginalized communities cannot and do not have decontextualized experiences with how socioscientific issues, such as exposure to COVID-19 as frontline essential workers, high Black infant mortality rates, air pollution leading to respiratory problems, and other issues, affect their communities. As PreK-12 science teachers and teacher educators strive to dismantle oppressive practices in their classrooms and curriculum, it would be helpful to learn from Black women science teachers who have been engaging in anti-racist practices before the racial awakenings of Summer 2020. In this study, three different virtual focus groups, or Sista Circles, were conducted with 18 Black women secondary science teachers. Ranging from 1 to 22 years of experience, Black women teachers across the country and international participants in Canada and Qatar participated in the Sista Circles. From intersectional qualitative analysis and narrative inquiry, the findings of the study reveal that Black women science teachers enact anti-racist science teaching by bringing something new to the community; using NGSS standards within the context of the community; teaching at the intersection of history, culture, and science learning and teaching; and building critical consciousness in the science classroom. Furthermore, the findings of the study have implications for the use of anti-racist frameworks within the context of science education that were authentically the practices of the Black women in the study. This study offers insights into how the critical consciousness of Black women teachers can be represented in the science classroom even in times of nonsupport from peers and administration. The power and necessity of Black women teachers are paramount in science classrooms specifically because of the neutral, apolitical ways science teaching has been approached in the past. The narratives and stories shared here exemplify how Black women science teachers transform science teaching and learning by displaying various acts of Criticality. 相似文献

In this article we assert a potential research agenda for the teaching and learning of science as inquiry as part of the JRST series on reform in science education. Drawing on the theoretical frameworks of cognitive and sociocultural constructivism, cultural models of meaning, the dialogic function of language, and transformational models of teacher education, we propose that more research is needed in the areas of teachers' beliefs, knowledge, and practices of inquiry‐based science, as well as, student learning. Because the efficacy of reform efforts rest largely with teachers, their voices need to be included in the design and implementation of inquiry‐based curriculum. As we review the literature and pose future research questions, we propose that particular attention be paid to research on inquiry in diverse classrooms, and to modes of inquiry‐based instruction that are designed by teachers. © 2001 John Wiley & Sons, Inc.

Recent calls for border crossing between reading and science have heightened the need to support science teachers in integrating reading into science and to verify the robustness of this approach in the context of inquiry‐based science. In this paper, we share what we did, found, and learned in a collaborative project in which a team of university‐based reading educators and school‐based science teachers worked together to infuse reading strategy instruction and quality science trade books into inquiry‐based sixth‐grade science classrooms. We suggest that infusing reading into middle school science enhances science teaching and learning, but is a complex, multifaceted undertaking. 相似文献

Science education researchers are concerned with preparing pre-service elementary teachers (PSETs) to teach in ways that support students to learn science in a meaningful way. Preparing elementary teachers to teach science is complicated given that they tend to be generalists and may not have the same experience with science as secondary teachers. During an elementary science methods course, we explored PSETs?? perspectives on the teaching and learning of science via a case study that included four PSETs. Using Frykholm??s (Journal of Curriculum and Supervision 19:125?C149, 2004) framework of ??educative?? and ??debilitating?? discomfort, we examined PSETs?? approaches to their own science learning and their approaches to science teaching. A theme apparent in PSETs?? perspectives was struggle. We described ways in which struggle was either educative or debilitating for PSETs, both in terms of their own learning and the ways in which they approached teaching. Some PSETs who struggled in their own learning developed learning experiences to engage their students in reform-based science teaching, while some PSETs developed learning experiences that prevented their students from experiencing any sort of struggle in their learning process. The ways in which these students dealt with their own learning struggles mirrored the ways in which they dealt with their struggles to become teachers of reform-based science instruction. Helping PSETs to deal with their feelings of discomfort with science content or ideas about the nature of science learning and teaching promoted by reform documents may be a key issue in developing their willingness to become facilitators of meaningful science learning. 相似文献

This is a narrative inquiry into the role of professional development in the construction of teaching practice by an exemplary urban high school science teacher. I collected data during 3 years of ethnographic participant observation in Marie Gonzalez’s classroom. Marie told stories about her experiences in ten years of professional development focused on inquiry science teaching. I use a social practice theory lens to analyze my own stories as well as Marie’s. I make the case that science teaching is best understood as mediated by socially-constructed identities rather than as the end-product of knowledge and beliefs. The cognitive paradigm for understanding teachers’ professional learning fails to consistently produce transformations of teaching practice. In order to design professional development with science teachers that is generative of new knowledge, and is self-sustaining, we must understand how to build knowledge of how to problematize identities and consciously use social practice theory. 相似文献
