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

In this investigation we employed a case study approach with qualitative and quantitative data sources to examine and discover the characteristics of the processes used by a midwestern U.S. school system to adopt and implement a new K–6 science curriculum. Analysis of data yielded several results. Elementary teachers received what they requested, a hands‐on science program with texts and kits. Teachers as a group remained in the early stages of the Concerns‐Based Adoption Model profile of concerns. Many K–6 teachers remained uncomfortable with teaching science. Teachers' attitudes regarding the new program were positive, and they taught more science. Teachers struggled with science‐as‐inquiry, with a science program they believe contained too many concepts and too much vocabulary, and with their beliefs that students learned more and loved the new hands‐on program. Traditional science teaching remained the norm. Administrative support was positive but insufficient to facilitate full implementation of the new program and more substantial change in teaching. Standardized science achievement test scores did not show an observable pattern of growth. It is concluded that a systematic, ongoing program of professional development is necessary to address teachers' concerns and help the district realize its goal of standards‐based K–6 science instruction. © 2004 Wiley Periodicals, Inc.

The use of inquiry‐based laboratory in college science classes is on the rise. This study investigated how five nonmajor biology students learned from an inquiry‐based laboratory experience. Using interpretive data analysis, the five students' conceptual ecologies, learning beliefs, and science epistemologies were explored. Findings indicated that students with constructivist learning beliefs tended to add more meaningful conceptual understandings during inquiry labs than students with positivist learning beliefs. All students improved their understanding of experiment in biology. Implications for the teaching of biology labs are discussed. © 2003 Wiley Periodicals, Inc. J Res Sci Teach 40: 986–1024, 2003 相似文献

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

ABSTRACTThis article is a collaboration involving a professor and three graduate students. Together, they explore lifescaping action research pedagogy guided by the participatory inquiry process. Since the lesson taught is not the lesson learned, the first author presents a perspective about teaching PIP followed by the graduate students’ collective responses enacting what they learned in three different school settings. 相似文献

We conducted a laboratory‐based randomized control study to examine the effectiveness of inquiry‐based instruction. We also disaggregated the data by student demographic variables to examine if inquiry can provide equitable opportunities to learn. Fifty‐eight students aged 14–16 years old were randomly assigned to one of two groups. Both groups of students were taught toward the same learning goals by the same teacher, with one group being taught from inquiry‐based materials organized around the BSCS 5E Instructional Model, and the other from materials organized around commonplace teaching strategies as defined by national teacher survey data. Students in the inquiry‐based group reached significantly higher levels of achievement than students experiencing commonplace instruction. This effect was consistent across a range of learning goals (knowledge, reasoning, and argumentation) and time frames (immediately following the instruction and 4 weeks later). The commonplace science instruction resulted in a detectable achievement gap by race, whereas the inquiry‐based materials instruction did not. We discuss the implications of these findings for the body of evidence on the effectiveness of teaching science as inquiry; the role of instructional models and curriculum materials in science teaching; addressing achievement gaps; and the competing demands of reform and accountability. © 2009 Wiley Periodicals, Inc.

Abstract The purpose of this article is to describe the development and implementation of a co‐teaching model at a small state university in the northeast. In addition, this article will share lessons learned from this experience by two professors, as well as describe the impact on the beliefs and teaching behaviors of their students. One of the professors is a member of the Department of Special Education and Rehabilitation, and the second is from the Department of Professional and Secondary Education. The co‐teaching initiative began in 1996 and continues until the present, with a graduate course on inclusionary practices taught collaboratively each fall. The impetus for the initiative came from an identified need for general education and special education teachers to co‐teach in classrooms where students with disabilities are included. Given that co‐teaching is an expected teacher behavior, the practice must be taught with intent and modeled by professors to increase the likelihood that it will be implemented successfully in P‐12 classrooms. 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.

This investigation was concerned with the effects of a social studies course on the philosophic orientations of history and geography students undergoing a programme in Postgraduate Diploma in Education (PGDE) at the University of Botswana. Forty‐eight of them were taught a social studies course to determine whether their social studies orientations would change at the end of the course with the use of the Barth/Shermis Social Studies Preference Scale. It was found that a large number of the students tended to tilt from the citizenship transmission orientation to the reflective inquiry orientation but with the majority of them in the social science orientation. It was concluded that an educational innovation is capable of bringing about a change in behaviour. 相似文献

Teacher beliefs about curriculum design affect the quality of science education in schools, but science researchers know little
about the interrelation of beliefs about alternative curriculum designs. This article describes a quantitative study of secondary
science teachers' beliefs about curriculum design. A 33-item Science Curriculum Orientation Inventory (SCOI) was developed
to measure five distinct orientations to curriculum: academic, cognitive processes, societycentred, humanistic, and technological.
Data were collected from 810 integrated science, chemistry, physics, and biology teachers in Hong Kong. A confirmatory factor
analysis of teacher responses to the SCOI indicated that science teachers' beliefs about curriculum design had a hierarchical
structure; the five distinct curriculum orientations were positively correlated, forming a second-order curriculum, meta-orientation.
Physics teachers were less society-oriented than biology, integrated science and chemistry teachers, and integrated science
teachers were more humanistic than physics teachers. Although science teachers' beliefs about any of the five alternative
curriculum designs did not vary with their teaching experience, the difference between beliefs about the cognitive processes
orientation and the humanistic orientation increased when teachers had gained more teaching experience. Implications of these
findings are discussed. 相似文献

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.

This qualitative study examined how and why research experiences for teachers (RETs) influenced middle and high school science teachers’ beliefs, attitudes, and values about teaching science as inquiry. Changes teachers reported after participating in the RET ranged from modifying a few lessons (belief change) to a comprehensive revision of what and how they taught to better reflect inquiry (attitude change). Some teachers who described comprehensively changing their instruction also described implementing actions meant to change science education within their respective schools, not just their own classrooms (value change). We present how and why teachers went about changes in their practices in relation to the researcher-created teacher inquiry beliefs system spectrum (TIBSS). The TIBSS conceptualizes the range of changes observed in participating teachers. We also describe the features of the RET and external factors, such as personal experiences and school contexts, that teachers cited as influential to these changes. 相似文献

A survey instrument was developed and administered to 1,222 K-12 mathematics and science teachers to measure their beliefs
about and use of inquiry in the classroom. Four variables (grade level taught, content area taught, level of support received,
and self-efficacy for teaching inquiry) were significantly correlated to two dependent variables, percentage of time that
students are engaged in inquiry during a typical lesson and the perceived ideal percentage of instructional time that should
be devoted to inquiry. Specifically, elementary school teachers reported using inquiry-based practices more than either middle-school
or high-school teachers; similarly, elementary-school teachers believed such practices should be used more often. All groups,
however, reported believing in an ideal percentage of time devoted to inquiry instruction that was significantly greater than
their reported percentage of time actually spent on inquiry instruction. A disordinal effect was found between grade level
taught and content area taught; at the elementary level, science teachers reported both an ideal and actual percentage of
time on inquiry higher than those reported by the math teachers, while at the high school level math teachers reported both
an ideal and actual percentage of time on inquiry higher than those reported by the science teachers. No correlations were
found between typical and ideal percentage of time devoted to inquiry and subject matter content knowledge training, gender,
years of teaching experience, or maximum degree earned. 相似文献

Orientations to research higher degree supervision 总被引：2，自引：0，他引：2
This study examines the beliefs of supervisors and PhD candidates about higher degree supervision and three other academic
domains: research; teaching; and learning. Interview data from 34 participants were categorised into four distinctive orientations
to supervision, each consisting of a network (plexus) of beliefs about the four domains. Although each orientation comprised
many beliefs, the orientations clearly differed in terms of two broad distinctions: whether the supervisor should direct and
take responsibility for the research (controlling beliefs) or should guide the process (guiding beliefs), and whether the focus of supervision should be more upon the research tasks to be completed (task-focussed beliefs) or upon the development of the candidates (person-focussed beliefs). These distinctions, plus the types of interconnections between the beliefs comprising each orientation, support
the conclusion that beliefs about teaching are central to each orientation, even though supervision is intimately concerned
with research. 相似文献

This study, conducted from a constructivist perspective, examined the belief system of a prospective elementary teacher (Barbara) about science teaching and learning as she developed professional knowledge within the context of reflective science teacher education. From an analysis of interviews, observation, and written documents, I constructed a profile of Barbara's beliefs that consisted of three foundational and three dualistic beliefs. Her foundational beliefs concerned (a) the value of science and science teaching, (b) the nature of scientific concepts and goals of science instruction, and (c) control in the science classroom. Barbara held dualistic beliefs about (a) how children learn science, (b) the science students' role, and (c) the science teacher's role. Her dualistic beliefs formed two contradictory nests of beliefs. One nest, grounded in lifelong science learner experiences, reflected a didactic teaching orientation and predominantly guided her practice. The second nest, not well grounded in experience, embraced a hands‐on approach and predominantly guided her vision of practice. The findings accentuate the complexity and nestedness of teachers' belief systems and underscore the significance of identifying prospective teachers' beliefs, espoused and enacted, for designing teacher preparation programs. © 2003 Wiley Periodicals, Inc.

This study investigated the impact of the use of computer technology on the enactment of “inquiry” in a sixth grade science classroom. Participants were 42 students (38% female) enrolled in two sections of the classroom and taught by a technology‐enthusiast instructor. Data were collected over the course of 4 months during which several “inquiry” activities were completed, some of which were supported with the use of technology. Non‐participant observation, classroom videotaping, and semi‐structured and critical‐incident interviews were used to collect data. The results indicated that the technology in use worked to restrict rather than promote “inquiry” in the participant classroom. In the presence of computers, group activities became more structured with a focus on sharing tasks and accounting for individual responsibility, and less time was dedicated to group discourse with a marked decrease in critical, meaning‐making discourse. The views and beliefs of teachers and students in relation to their specific contexts moderate the potential of technology in supporting inquiry teaching and learning and should be factored both in teacher training and attempts to integrate technology in science teaching. © 2006 Wiley Periodicals, Inc.

“The fish becomes aware of the water in which it swims” is a metaphor that represents Yuli’s revelatory journey about the hidden power of culture in her personal identity and professional teaching practice. While engaging in a critical auto/ethnographic inquiry into her lived experience as a science teacher in Indonesian and Australian schools, she came to understand the powerful role of culture in shaping her teaching identity. Yuli realised that she is a product of cultural hybridity resulting from interactions of very different cultures—Javanese, Bimanese, Indonesian and Australian. Traditionally, Javanese and Indonesian cultures do not permit direct criticism of others. This influenced strongly the way she had learned to interact with students and caused her to be very sensitive to others. During this inquiry she learned the value of engaging students in open discourse and overt caring, and came to realise that teachers bringing their own cultures to the classroom can be both a source of power and a problem. In this journey, Yuli came to understand the hegemonic power of culture in her teaching identity, and envisioned how to empower herself as a good teacher educator of pre-service science teachers. 相似文献

The purpose of this case study is to delve into the complexities of how preservice science teachers’ science teaching orientations, viewed as an interrelated set of beliefs, interact with the other components of pedagogical content knowledge (PCK). Eight preservice science teachers participated in the study. Qualitative data were collected in the form of content representation, responses to an open-ended instrument, and semi-structured interviews. Preservice teachers’ orientation and PCK were analyzed deductively. Constant comparison analysis of how their orientation interacted with other PCK components revealed three major themes: (1) one’s purpose for science teaching determines the PCK component(s) with which it interacts, (2) a teacher’s beliefs about the nature of science do not directly interact with his/her PCK, unless those beliefs relate directly to the purposes of teaching science, and (3) beliefs about science teaching and learning mostly interact with knowledge of instructional strategies. Implications for science teacher education and research are discussed. 相似文献
