What teaching practices foster inquiry and promote students to learn challenging subject matter in urban schools? Inquiry‐based instruction and successful inquiry learning and teaching in project‐based science (PBS) were described in previous studies (Brown & Campione, 1990 ; Crawford, 1999 ; Krajcik, Blumenfeld, Marx, Bass, & Fredricks, 1998 ; Krajcik, Blumenfeld, Marx, & Solloway, 1994 ; Minstrell & van Zee, 2000 ). In this article, we describe the characteristics of inquiry teaching practices that promote student learning in urban schools. Teaching is a major factor that affects both achievement of and attitude of students toward science (Tamir, 1998 ). Our involvement in reform in a large urban district includes the development of suitable learning materials and providing continuous and practiced‐based professional development (Fishman & Davis, in press; van Es, Reiser, Matese, & Gomez, 2002 ). Urban schools face particular challenges when enacting inquiry‐based teaching practices like those espoused in PBS. In this article, we describe two case studies of urban teachers whose students achieved high gains on pre‐ and posttests and who demonstrated a great deal of preparedness and commitment to their students. Teachers' attempts to help their students to perform well are described and analyzed. The teachers we discuss work in a school district that strives to bring about reform in mathematics and science through systemic reform. The Center for Learning Technologies in Urban Schools (LeTUS) collaborates with the Detroit Public Schools to bring about reform in middle‐school science. Through this collaboration, diverse populations of urban‐school students learn science through inquiry‐oriented projects and the use of various educational learning technologies. For inquiry‐based science to succeed in urban schools, teachers must play an important role in enacting the curriculum while addressing the unique needs of students. The aim of this article is to describe patterns of good science teaching in urban school. © 2006 Wiley Periodicals, Inc. J Res Sci Teach 43: 722–745, 2006 相似文献

This two‐year school‐wide initiative to improve teachers’ pedagogical skills in inquiry‐based science instruction using a constructivist sociocultural professional development model involved 30 elementary teachers from one school, three university faculty, and two central office content supervisors. Research was conducted for investigating the impact of the professional development activities on teachers’ practices, documenting changes in their philosophies, instruction, and the learning environment. This report includes teachers’ accounts of philosophical as well as instructional changes and how these changes shaped the learning environment. For the teachers in this study, examining their teaching practices in learner‐centered collaborative group settings encouraged them to critically analyze their instructional practices, challenging their preconceived ideas on inquiry‐based strategies. Additionally, other factors affecting teachers’ understanding and use of inquiry‐based strategies were highlighted, such as self‐efficacy beliefs, prior experiences as students in science classrooms, teacher preparation programs, and expectations due to federal, state, and local mandates. These factors were discussed and reconciled, as they constructed new understandings and adapted their strategies to become more student‐centered and inquiry‐based. 相似文献

The purpose of this study was to investigate the beliefs of six experienced high school science teachers about (1) what is successful science learning; (2) what are the purposes of laboratory in science teaching; and (3) how inquiry is implemented in the classroom. An interpretive multiple case study with an ethnographic orientation was used. The teachers' beliefs about successful science learning were substantively linked to their beliefs about laboratory and inquiry implementation. For example, two teachers who believed that successful science learning was deep conceptual understanding, used verification labs primarily to illustrate these concepts and used inquiry as a type of isolated problem‐solving experience. Another teacher who believed that successful science learning was enculturation into scientific practices used inquiry‐based labs extensively to teach the practices of science. Tension in competing beliefs sets and implications for reform are discussed. ? 2004 Wiley Periodicals, Inc. J Res Sci Teach 41: 936‐960, 2004. 相似文献

We present an inquiry‐based, aquatic science professional development (PD) for upper‐elementary, middle, and high school teachers and examine changes in student outcomes in light of participating teachers’ characteristics and the grade band of the students. Our study lends support to the assertion that inquiry‐ and content‐focused PD, paired with classroom implementation, can effectively improve student learning. Our findings indicate that students improved in their nature of science (NOS) and aquatic science content knowledge and that these changes depended in some ways on the participating teachers’ characteristics and adherence to the program. The students’ improvements were amplified when their teachers adhered more closely to the PD activities during their classroom implementation. The teachers’ previous science PD experience and pre‐PD understanding of inquiry‐based teaching also explained some of the variability in student growth. In both NOS and content, students of teachers with less prior science‐PD experience benefited more. Grade band also explained variation in student outcomes through interactions with teacher‐characteristic variables. In high school, students of teachers with lower pre‐PD inquiry knowledge appeared to learn more about NOS. Our results suggest that inquiry and content training through PD may minimize disparities in teaching due to inexperience and lack of expertise. Our study also demonstrates the value of PD that teaches a flexible approach to inquiry and focuses on underrepresented, interdisciplinary content areas, like aquatic science. © 2017 Wiley Periodicals, Inc.

The present study deals with a school‐based professional development trajectory for secondary science teachers, aiming at scaffolding teachers in open‐inquiry teaching for the topic of water quality. Its design was based on the leading principle of ‘guiding by scaffolding’. Seven experienced teachers participated in institutional meetings and teaching at school. The research focused on designing scaffolding tools, addressing these tools in the meetings, and implementing them in the classroom. The main research data were obtained from meetings, classroom discussions, and observations. The results indicated that the professional development trajectory has promoted teachers’ learning of scaffolding students in open inquiry, especially the ability to know when and how to give students a well‐balanced combination of ‘structure’ for open‐inquiry learning and sufficient ‘space’ for that. The implications for science teacher education are discussed. 相似文献

Six remedial reading teachers in a large, rural school district participated in a form of professional development called Teaching as Intentional Learning, based on an inquiry process. Their topic of inquiry was formative assessment. Professional development comprised both direct instruction and inquiry learning in teachers’ own classrooms. This study describes the strategies they experimented with, their professional growth in formative assessment, and effects on students. All six teachers showed important professional growth, as indicated by their own reflections and also by their supervisor’s observations. In First Grade, at‐risk students assigned to these project teachers had increased reading readiness scores on one measure (DIBELS PSF) compared with at‐risk students assigned to non‐project teachers. 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.

The ENVISION professional development model uses active teacher involvement in inquiry and inquiry‐based teaching to enhance teachers' understandings about inquiry‐based study of local environmental problems and teaching science using inquiry. Teachers also design and implement professional development for their school‐based colleagues about teaching environmental science through inquiry. Therefore, professional development is conducted at two levels. ENVISION staff train teachers directly (called Level I participants) and these Level I participants in turn train their school colleagues (called Level II participants). The study reported here was designed to evaluate the effectiveness of this dual‐level professional development strategy. Results based on the first two years of the program revealed that: Level I participants enhanced their understanding of inquiry and inquiry teaching, with 25 out 30 (83%) changing their classroom practice; and that 21 out of 31 (68%) of Level II participants changed their classroom practice as a result of participating in Level I peer training. Peer training that involved modeling and practicing techniques and activities was particularly effective in producing change in practice for Level II teachers. 相似文献

As part of a larger project aimed at promoting science and literacy for culturally and linguistically diverse elementary students, this study has two objectives: (a) to describe teachers' initial beliefs and practices about inquiry‐based science and (b) to examine the impact of the professional development intervention (primarily through instructional units and teacher workshops) on teachers' beliefs and practices related to inquiry‐based science. The research involved 53 third‐ and fourth‐grade teachers at six elementary schools in a large urban school district. At the end of the school year, teachers reported enhanced knowledge of science content and stronger beliefs about the importance of science instruction with diverse student groups, although their actual practices did not change significantly. Based on the results of this first year of implementation as part of a 3‐year longitudinal design, implications for professional development and further research are discussed. © 2004 Wiley Periodicals, Inc.

Curriculum materials are crucial tools with which teachers engage students in science as inquiry. In order to use curriculum materials effectively, however, teachers must develop a robust capacity for pedagogical design, or the ability to mobilize a variety of personal and curricular resources to promote student learning. The purpose of this study was to develop a better understanding of the ways in which preservice elementary teachers mobilize and adapt existing science curriculum materials to plan inquiry‐oriented science lessons. Using quantitative methods, we investigated preservice teachers' curriculum design decision‐making and how their decisions influenced the inquiry orientations of their planned science lessons. Findings indicate that preservice elementary teachers were able to accurately assess how inquiry‐based existing curriculum materials are and to adapt them to make them more inquiry‐based. However, the inquiry orientations of their planned lessons were in large part determined by how inquiry‐oriented curriculum materials they used to plan their lessons were to begin with. These findings have important implications for the design of teacher education experiences that foster preservice elementary teachers' pedagogical design capacities for inquiry, as well as the development of inquiry‐based science curriculum materials that support preservice and beginning elementary teachers to engage in effective science teaching practice. © 2009 Wiley Periodicals, Inc.

Reform based curriculum offer a promising avenue to support greater student achievement in science. Yet teachers frequently adapt innovative curriculum when they use them in their own classrooms. In this study, we examine how 19 teachers adapted an inquiry‐oriented middle school science curriculum. Specifically, we investigate how teachers' curricular adaptations (amount of time, level of completion, and activity structures), teacher self‐efficacy (teacher comfort and student understanding), and teacher experience enacting the unit influenced student learning. Data sources included curriculum surveys, videotape observations of focal teachers, and pre‐ and post‐tests from 1,234 students. Our analyses using hierarchical linear modeling found that 38% of the variance in student gain scores occurred between teachers. Two variables significantly predicted student learning: teacher experience and activity structure. Teachers who had previously taught the inquiry‐oriented curriculum had greater student gains. For activity structure, students who completed investigations themselves had greater learning gains compared to students in classrooms who observed their teacher completing the investigations as demonstrations. These findings suggest that it can take time for teachers to effectively use innovative science curriculum. Furthermore, this study provides evidence for the importance of having students actively engaging in inquiry investigations to develop understandings of key science concepts. © 2010 Wiley Periodicals, Inc., J Res Sci Teach 48: 149–169, 2011 相似文献

This study has two purposes: the first is to explore experienced science teachers’ perspectives on inquiry teaching, and the second is to categorize these perspectives into patterns. Fifteen junior high school science teachers experienced at inquiry teaching were selected, and a semi-structured interview was conducted to collect the teachers’ perspectives on inquiry and inquiry teaching. The findings indicate that these experienced science teachers hold multiple perspectives on inquiry and inquiry teaching. The two patterns generated from these teachers’ perspectives of inquiry and inquiry teaching were systematic-based inquiry instruction and learning-based inquiry instructions. Suggestions for science teacher educators are discussed in this paper. 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.

Bridging the Gap Between the Language of Science and the Language of School Science Through the Use of Adapted Primary Literature 总被引：1，自引：0，他引：1
In this paper we make the case that the language of school science and the language of science are widely divergent. We trace
the divergence to a simple view of reading that prevails not only in science education but in most of schooling. Based upon
the importance of language in science and the role of language in capturing the essential nature of scientific reasoning,
we conclude that conceiving of reading as a form of inquiry could assist in bringing the two languages more into alignment.
We recommend the use of adapted primary literature as one curriculum and instruction innovation that can be useful in illustrating
the nature of reading as inquiry. 相似文献

The Biology Workbench (BW) is a web‐based tool enabling scientists to search a wide array of protein and nucleic acid sequence databases with integrated access to a variety of analysis and modeling tools. The present study examined the development of this scientific tool and its consequent adoption into the context of high school science teaching in the form of the Biology Student Workbench (BSW). Participants included scientists, programmers, science educators, and science teachers who played key roles along the pathway of the design and development of BW, and/or the adaptation and implementation of BSW in high school science classrooms. Participants also included four teachers who, with their students, continue to use BSW. Data sources included interviews, classroom observations, and relevant artifacts. Contrary to what often is advocated as a major benefit accruing from the integration of authentic scientific tools into precollege science teaching, classroom enactments of BSW lacked elements of inquiry and were teacher‐centered with prescribed convergent activities. Students mostly were preoccupied with following instructions and a focus on science content. The desired and actual realizations of BSW fell on two extremes that reflected the disparity between scientists' and educators' views on science, inquiry science teaching, and the related roles of technological tools. Research on large‐scale adoptions of technological tools into precollege science classrooms needs to expand beyond its current focus on teacher knowledge, skills, beliefs, and practices to examine the role of the scientists, researchers, and teacher educators who often are involved in such adoptions. © 2010 Wiley Periodicals, Inc.

Developing students’ skills to pose and respond to questions and actively engage in inquiry behaviours enables students to problem solve and critically engage with learning and society. The aim of this study was to analyse the impact of providing teachers with an intervention in inquiry pedagogy alongside inquiry science curriculum in comparison to an intervention in non-inquiry pedagogy alongside inquiry science curriculum on student questioning and other inquiry behaviours. Teacher participants in the comparison condition received training in four inquiry-based science units and in collaborative strategic reading. The experimental group, the community of inquiry (COI) condition, received training in facilitating a COI in addition to training in the same four inquiry-based science units. This study involved 227 students and 18 teachers in 9 primary schools across Brisbane, Australia. The teachers were randomly allocated by school to one of the two conditions. The study followed the students across years 6 and 7 and students’ discourse during small group activities was recorded, transcribed and coded for verbal inquiry behaviours. In the second year of the study, students in the COI condition demonstrated a significantly higher frequency of procedural and substantive higher-order thinking questions and other inquiry behaviours than those in the comparison condition. Implementing a COI within an inquiry science curriculum develops students’ questioning and science inquiry behaviours and allows teachers to foster inquiry skills predicated by the Australian Science Curriculum. Provision of inquiry science curriculum resources alone is not sufficient to promote the questioning and other verbal inquiry behaviours predicated by the Australian Science Curriculum. 相似文献

Teachers play a central role in inquiry science classrooms. In this study, we investigate how seven teacher variables (i.e., gender, experience, perceived importance of inquiry and traditional teaching, workshop attendance, partner teacher, use of technology) affect student knowledge integration understanding of science topics drawing on previous research. Using a two‐level hierarchical linear model, we analyze year‐end knowledge integration performance of 4,513 students taught by 40 teachers across five states. Results indicate that students of teachers who value inquiry teaching strategies have significantly higher levels of knowledge integration understanding than those of teachers who believe in traditional teaching methods. In addition, workshop attendance and having a partner teacher teaching the same unit in the same school also have a positive impact on students' knowledge integration levels. The results underscore the importance of professional development and collegial support in enhancing student success in inquiry science. © 2009 Wiley Periodicals, Inc.

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

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

Science enrichment programmes housed outside traditional school settings can offer students from traditionally under‐resourced schools valuable opportunities to access authentic scientific tools and practices. The present study contributes to our understanding of this potential and how it can best be realised through an analysis of the students’ own perspectives on a specific out‐of‐school programme—a one‐year partnership with a university‐based science outreach programme, which culminated in a half‐day laboratory experience for a total of 292 secondary students (ages 11–18 years). Extensive data were collected on this experience, including detailed field notes and video recordings of the classes’ visits to the university as well as the planning meetings with teachers at the beginning and end of the school year, surveys of the participating students, and surveys and interviews of the teachers, and were analysed both qualitatively and quantitatively using a grounded theory approach. Building on the valuable perspectives of the participating students, and comparing them with those of their eight teachers, this study confirms that carefully designed collaborative out‐of‐school inquiry programmes have the potential to broaden students’ (especially those from under‐resourced schools) experiences of science as well as bridge them to school science. 相似文献
