This study investigated a professional development model designed to improve teachers' inquiry teaching efficacy as well as the quality of their inquiry instruction through engaging teachers in practice-teaching and reflection sessions. The programme began with a two-week summer Institute focused on both inquiry pedagogy and science content and continued with academic year support for participants' inquiry implementation. An inquiry teaching efficacy instrument was administered 3 times to 25 teacher participants to gauge changes in their personal self-efficacy and outcome expectancy across 5 essential features of classroom inquiry. To examine actual practices, pre/post classroom observations of the teachers' inquiry enactments were evaluated using a quality of inquiry observation protocol. Following the summer Institute, teachers had statistically significant increases in their self-efficacy for teaching inquiry in four of the five essential features and increases in one of the five essential features for outcome expectancy. Teachers' quality of inquiry teaching also increased after the professional development programme. We discuss implications of this PD model for moving teachers towards implementation of new instructional techniques as well as the influence of a supportive school community on teachers’ efficacy with inquiry instruction.  相似文献

Learning to teach science as inquiry in the rough and tumble of practice   总被引:2,自引:0,他引:2  
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

This study examined prospective elementary teachers' learning about scientific inquiry in the context of an innovative life science course. Research questions included: (1) What do prospective elementary teachers learn about scientific inquiry within the context of the course? and (2) In what ways do their experiences engaging in science investigations and teaching inquiry‐oriented science influence prospective elementary teachers' understanding of science and science learning and teaching? Eleven prospective elementary teachers participated in this qualitative, multi‐participant case study. Constant comparative analysis strategies attempted to build abstractions and explanations across participants around the constructs of the study. Findings suggest that engaging in scientific inquiry supported the development more appropriate understandings of science and scientific inquiry, and that prospective teachers became more accepting of approaches to teaching science that encourage children's questions about science phenomena. Implications include careful consideration of learning experiences crafted for prospective elementary teachers to support the development of robust subject matter knowledge.  相似文献

This article investigates three teachers' conceptions and use of inquiry‐based instructional strategies throughout a professional development program. The professional development program consisted of a 2‐week summer inquiry institute and research experience in university scientists' laboratories, as well as three academic year workshops. Insights gained from an in‐depth study of these three secondary teachers resulted in a model of teacher conceptions that can be used to direct future inquiry professional development. Teachers' conceptions of inquiry teaching were established through intensive case–study research that incorporated extensive classroom observations and interviews. Through their participation in the professional development experience, the teachers gained a deeper understanding of how to implement inquiry practices in their classrooms. The teachers gained confidence and practice with inquiry methods through developing and presenting their institute‐developed inquiry lessons, through observing other teachers' lessons, and participating as students in the workshop inquiry activities. Data analysis revealed that a set of four core conceptions guided the teachers' use of inquiry‐based practices in their classrooms. The teachers' conceptions of science, their students, effective teaching practices, and the purpose of education influenced the type and amount of inquiry instruction performed in the high school classrooms. The research findings suggest that to be successful inquiry professional development must not only teach inquiry knowledge, but it must also assess and address teachers' core teaching conceptions. © 2007 Wiley Periodicals, Inc.

This study explored preservice elementary teachers' and their mentors' understanding of the essential features of inquiry-based teaching through the use of evidence-based reflection. The web-based video analysis tool (VAT) system was used to support preservice teachers' and mentors' evidence-based reflection during field experiences. Major data sources included VAT reflections and individual interviews. Data analysis indicated that the preservice teachers had been involved in various activities designed to support their understanding of inquiry features in a science methods class; they did not implement all of the features in their actual teaching. Both preservice teachers and mentors had difficulty connecting appropriate inquiry features to each teaching episode, which indicates their lack of understanding of inquiry. Both the preservice teachers and mentors had different levels of understanding for each feature. That is, they tended to understand certain features better than others. They interpreted each feature of inquiry-based science teaching too broadly. They also either had a teacher-centered view or tended to focus on issues unrelated to science teaching.  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

The purpose of this investigation was to determine if an instrument, originally designed to classify levels of teachers' questions on the basis of logical operations, could be utilized to measure the level of inquiry present in a classroom discussion and to determine if the inquiry questioning behavior of the teacher influenced student achievement. The results of the study show that the modified classification scheme could accurately and reliably measure the inquiry level of teachers' classroom questions. The data also indicated that teachers who ask a greater proportion of high inquiry questions cause a greater change in students as measured by an achievement examination.  相似文献

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

In this research project, we investigated two beginning secondary science teachers' efforts to learn to teach science in ways that build from and celebrate the ethnic, gender, linguistic, and academic diversity of their students. To do so, we followed Troy and Brian from their preservice teacher education experiences through their first year of teaching 8th grade physical science at local junior high schools. We also conducted a follow‐up observation and interview with each participant after he had moved past the beginning stage of survival in the teaching profession—once in his fourth year of public school science teaching. Through qualitative analysis of interviews, classroom observations, and teachers' written work, we identified patterns and explored commonalities and differences in Troy and Brian's views and practices tied to equity over time. In particular, we examined successes and challenges they encountered in learning to teach science for all (a) from their students, (b) from inquiry into practice, and (c) from participation in professional communities. In our implications, we suggest ways teacher educators and induction professionals can better support beginning teachers in learning to teach science to all students. In particular, we highlight the central roles both individual colleagues and collective school cultures play in aiding or impeding beginning teachers' efforts to learn from students, from practice, and from professional communities. © 2006 Wiley Periodicals, Inc.

The Next Generation Science Standards (NGSS) strives to shift science learning from the teacher as a single cognitive agent, to a classroom community in which participants are working together in directing the classroom's communal knowledge to figure out questions about how phenomena occur, and building, testing, and refining their ideas to address those questions. To achieve this type of classroom environment, teachers should attend to students' knowledge and ideas and pay attention to how students are located within teacher-led interactions, such as being positioned as active discussants or designated listeners. In this study, we explore if and how this is occurring in the NGSS era. We used a naturalistic inquiry to explore how an experienced first-grade teacher used a new NGSS-aligned unit that called for students to use the science and engineering practices (SEP) to build content knowledge. We used a macro-analytic lens to answer the research question “how are class discussions shaped to address the SEP”? We used a micro-analytic lens to answer the research question “how are students positioned during these science discussions in this classroom?” Evidence suggests that the teachers' whole class discussions incorporated and involved the SEP which were specified in the unit lessons for content learning. However, on a micro-analytic level, we found that few students were positioned as active discussants. The teacher heavily relied on those students who could provide succinct and clearly relevant answers while positioning the remainder of the students as silent spectators. Implications from this research suggest that not only new NGSS curriculum materials need to focus on what students should know and do but they also need to address heuristics for teachers that show them how to position all of their students as active doers of science so all students have opportunities to build deeper, core science knowledge.  相似文献

The purpose of this study was to examine the experiences of three science teachers attempting to transform their practice by conducting action research on feminist science teaching. The teachers engaged in systematic, self‐critical inquiry of their own practice and joined 8 other science teachers to engage in collaborative conversations about the nature of science, science teaching, and science education as a way of coming to a better understanding of how science can be taught for a more diverse group of students. Data were gathered via semistructured interviews, whole‐group discussions, classroom observations, and review of supporting documents. Data analysis was based on narrative inquiry, where particular attention was given to the construction and reconstruction of the teachers' stories of their practical inquiries. Results indicated that the teachers as researchers of their own practice gained new knowledge about feminist science teaching and, furthermore, generated a cluster of pedagogical possibilities for inclusive, dynamic science teaching. © 2006 Wiley Periodicals, Inc.

As is the case with most developed countries, pressures from various sectors of society have seen computers make a big presence in Australian education systems in the last decade. In the state of Victoria, integrating learning technology (LT) into all key learning areas of every school's curriculum has been a priority policy of governments. Over the last 8–10 years, large amounts of money have been provided to set schools up with computers and associated technologies. In the area of science, a range of LT resources is available for use in the teaching and learning processes in the classroom. However, there has been limited evaluation into teachers' attitudes towards, and types of, methodology and effectiveness of usage of computer-based technologies in knowledge construction. Using both quantitative and qualitative methods, a study aimed at identifying science teachers' opinions and practices with the use of computer-based technologies in their teaching has been carried out in Victorian government schools. The focus of this paper is on the attitudes of these science teachers towards the use of computer-based technologies in their teaching. The study showed that most teachers have embraced the introduction of these technologies into the school structure well and are generally positive about their potential in the classroom. However, their use in the classrooms is infrequent and often on an ad hoc basis. A range of obstacles preventing the use of these technologies are identified and discussed in this paper.  相似文献

Science teachers use analogies that display a rich variety of form and content. An account of science teacher analogies that relies solely on systems of analysis imported from other fields of inquiry tends to obscure the unique features of these analogies as they operate within classroom discourse. This study examines teachers' analogies in context and highlights some of their special characteristics. The purpose of this analysis is to increase our understanding of how analogies operate in naturalistic instructional settings and to generate new research questions about science teaching and learning in view of the broader dimensions of the curriculum. Science isa very human activity. It involves human actors and judgements, rivalries and antagonisms, mysteries and surprises, the creative use of metaphor and analogy. It is fallible, often uncertain, and sometimes creatively ambiguous [Lemke, 1990, p. 134].  相似文献

The last two decades have witnessed the gradual implementation of integrated science curriculum at the junior secondary level in China. However, in most provinces of China, the implementation is not as successful as expected. Challenges were reported, yet without fine-grained investigation, with respect to science teachers' instruction on integrated science. In this study, we aim to detect major problems by investigating the instruction of integrated science at the secondary level. Classroom observation focused on the teacher and student verbal behavior, teachers' competency of instructional organization, their presentation of instructional content, and the organization of learning activities. Findings revealed that students were provided with limited opportunities for participating and engaging in learning as science teachers were dominant in classroom talk. Teachers emphasized on the integration of knowledge within one subject (within-subject knowledge), but not the integration of knowledge between subjects (cross-subject knowledge), resulting in the unsuccessful instruction of the integrative content. What is more, teachers were inadequately competent in designing and delivering science, technology and society content, scientific inquiry and scientific experiments, which also affected the quality of instruction on integrated science.  相似文献

We came to this study with a set of beliefs about good science teaching that had been heavily influenced by the constructivist literature of the past decade. In this article we reexamine some of our own assumptions about good teaching by exploring the classroom practices of an experienced physics teacher. This teacher did not fit the mold of the constructivist teacher and, yet, there was much to suggest that he was meeting the needs of the students in his class. His methods were almost entirely whole class—focusing mainly on physics content, examination technique and algorithm practice. Our close observation of this teacher in his Grade 11 classroom over several months suggests an alternative framework for examining his work. We examine this framework through a number of themes: teacher confidence, the structure of the discipline, student motivation, trust, and the cultural context of learning. We argue for a broader view of good science teaching than that proposed by the constructivist literature, one that takes into account teachers' and students' understandings of science in relation to their social and cultural contexts.  相似文献

This study continues research previously conducted by a nine‐university collaborative, the Salish I Research Project, by exploring science teachers' beliefs and practices with regard to inquiry‐oriented instruction. In this study, we analyzed the relationship among secondary science teachers' preparation, their beliefs, and their classroom practices after completion of a course designed to provide authentic inquiry experiences. From Teacher Pedagogical Philosophy Interview data and Secondary Science Teacher Analysis Matrix observational data, we analyzed links between the teachers' conveyed beliefs and observed practice regarding the teachers' actions (TA) and students' actions (SA). Also presented is a listing of teachers' perceived influences from university preparation course work. Results indicated that 7 of the 8 teachers professed a belief in teacher‐centered or conceptual style with regard to TA and SA. The observational results indicated that 7 of the 8 teachers displayed a teacher‐centered or conceptual style with regard to TA and SA. Inconsistencies between interview and observational data were unexpected, as half of the teachers professed slightly greater teacher‐centered styles with regard to TA than what they actually practiced in their classrooms. All teachers reported that an inquiry‐based science course was valuable. © 2006 Wiley Periodicals, Inc. J Res Sci Teach 43: 938–962, 2006  相似文献

This paper describes Ecuadorian in-service teachers and their science teaching practices in public primary schools. We wanted to find out to what extent teachers implement inquiry activities in science teaching, the level of support they provide, and what type of inquiry they implement. Four questionnaires applied to 173 teachers resulted in the identification of high context beliefs and moderately high self-efficacy beliefs. Teachers declared to implement activities mostly to develop understanding of the material, as contrast to actual manipulation of data and/or coming to conclusions. They adopt rather a strictly guided approach in contrast to giving autonomy to learners to work on their own. Finally, teachers keep control with regard to question formulation and choice in solution procedures, which constrains the development of real inquiry. When comparing teacher beliefs, we found that teachers' context beliefs make a difference in the level of support that teachers provide to their students. Teachers with lower context beliefs ask students to perform inquiry activities on their own to a lesser extent when compared with teachers with higher context beliefs. This implies that further research on the implementation of inquiry in science teaching should take into account teachers' differences in their context beliefs. We also found out that the use of high or low support in inquiry activities remained the same for teachers with either higher or lower self-efficacy beliefs.  相似文献

Students' questions play an important role in meaningful learning and scientific inquiry. They are a potential resource for both teaching and learning science. Despite the capacity of students' questions for enhancing learning, much of this potential still remains untapped. The purpose of this paper, therefore, is to examine and review the existing research on students' questions and to explore ways of advancing future work into this area. The paper begins by highlighting the importance and role of students' questions from the perspectives of both the learner and the teacher. It then reviews the empirical research on students' questions, with a focus on four areas: (1) the nature and types of these questions; (2) the effects of teaching students questioning skills; (3) the relationship between students' questions and selected variables; and (4) teachers' responses to, and students' perceptions of, students' questions. Following this, some issues and implications of students' questions for classroom instruction are discussed. The paper concludes by suggesting several areas for future research that have significant value for student learning.  相似文献
