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

Internationally, considerable reform in science education is occurring which promotes constructivist philosophies and advocates constructivist-inspired pedagogical strategies that are new to many teachers. This paper reports on the supporting factors necessary for teacher professional growth and the issues of concern that were evident during one primary teacher's successful implementation of a unit of work based on a draft of a new state-wide science syllabus which proposes such approaches. One researcher (CEP) provided guidance during the writing and implementation of the unit through professional development workshops complemented by ongoing collegial support. The analysis of the teacher's practice reveals that professional growth required a willingness of the teacher to engage with change and modify his professional practice. The support factors for teacher growth consisted of an appropriate program of professional development, teacher understanding of the elements of the curriculum innovation, and successful experiences in implementing new approaches. In contrast, the issues of concern were: the adequacy of support for planning including the time required to understand the innovation and make changes to teaching practice; science equipment; teacher knowledge; classroom management strategies; and ways to cope with change. Understanding of these support factors and issues of concern is vital for the successful implementation of science curriculum innovations. 相似文献

Science teacher beliefs and classroom practice related to constructivism and factors that may influence classroom practice
were examined in this cross-case study. Data from four science teachers in two schools included interviews, demographic questionnaire,
Classroom Learning Environment Survey (preferred/perceived), and classroom observations and documents. Using an inductive
analytic approach, results suggested that the teachers embraced constructivism, but classroom observations did not confirm
implementation of these beliefs for three of the four teachers. The most preferred constructivist components were personal
relevance and student negotiation; the most perceived component was critical voice. Shared control was the least preferred,
least perceived, and least observed constructivist component. School type, grade, student behavior/ability, curriculum/standardized
testing, and parental involvement may influence classroom practice. 相似文献

Abstract Examining how teachers structure the activities in a unit and how they facilitate classroom discussion is important to understand how innovative technology-rich curricula work in the context of classroom instruction. This study compared 2 enactments of an inquiry curriculum, then examined students' learning outcomes in classes taught by 2 teachers. The quantitative data show that there were significant differences in the learning outcomes of students in classes of the 2 teachers. This study then examined classroom enactments by the 2 teachers to understand the differences in the learning outcomes. This research specifically focused on how teacher-led discussions (a) helped connect the activities within a curriculum unit and (b) enabled deeper conceptual understanding by helping students make connections between science concepts and principles. This study examined the role that teacher facilitation played in helping students focus on the relations between the various activities in the unit and the concepts that they were learning. The results point to important differences in the 2 enactments, helping to understand better what strategies might enable a deeper conceptual understanding of the science content. 相似文献

合科初中科学课程开设是我国新课改的一个突破和亮点,教师知识是影响其实施的一个强影响因素。基于对浙江省某市合科初中科学教师的课堂观察与访谈,研究发现：一是教师知识越专业、越丰富,教学就可能越成功、越有效,否则将有很多困难;二是教师最难适应的非专业知识教学貌似生物、天文、地理等,实则物理更严重;三是进行有效教学的教师,其各类知识是不可分割的,它们相互联系、相互组织。可以说,教师知识发展水平决定着合科初中科学课程实施质量。为深化实施,教师知识亟待发展：一是夯实合科初中科学学科内容知识,完善知识结构;二是促进科学本质理解,强化课程整合意识,体现科学探究精神。最有效路径是,善用教师发展平台,重在自我提升。 相似文献

The study attempts to identify the factors which affect teacher's reluctance to teach science, then explains an approach to
help teachers teach science in a worthwhile manner over the school year while monitoring any changes in their confidence and
competence. It was found that the condidence and competence of the teachers improved during the year such that they were able
to teach successful science lessons on a regular basis.

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.

The study examined the impact of curriculum reform on teaching practice in primary mathematics in mainland China. The participants included 58 fifth grade mathematics teachers from 20 schools. Thirty-two of the classrooms had utilized a reform curriculum for 5 years prior to conducting the study, and the remaining 26 had been using the conventional curriculum. Each of the 58 teachers was videotaped for 3 of his/her classes during a 3-day period and the videotaped class sessions provided the data source for the study. The focus of the study was on the instructional tasks that were implemented in the classrooms and on the teacher and student interaction. Results indicated that a greater proportion of high cognitive level tasks were implemented in the reform classrooms when compared to those in the non-reform classrooms. Numerical symbolic representation as well as single-solution strategies were dominant in the instructional tasks for both groups. However, in the reform classes a higher proportion of instructional tasks were used that involved visual illustrations and hands-on manipulation and multiple-solution strategies. An analysis of classroom discourse showed that most of the teacher questions were related to memorizing exercises and explanations of answers. However, the teachers from the reform classrooms were more likely to ask students to describe the procedure that led to an answer and to inquire further into students’ responses. The results indicated positive changes in classroom practice resulting from implementation of the new curriculum. 相似文献

This study examined the level of instructional use of Internet among science teachers involved with an in-service professional development project. An instrument on Level of Use of innovation was modified for the study. A criterion sample of teachers to be interviewed via telephone was randomly selected from a pool of 347 K–12 teachers. Somers' d and contingency coefficients were determined to see whether any relationship exists between a teacher's Level of Use and the following categories: (a) amount of experience with the Internet; (b) availability of resources support and access to the Internet in classroom and at home; (c) number of teacher and student users at school, (d) gender; and (e) type of school. Results of step-wise multiple regression indicate that classroom access, instructional experience of using Internet with students, availability of resource support and number of teacher users at school are the best predictors of teacher's Level of Use. Chi square test for comparisons between groups of completers and noncompleters of On-Line West Virginia K–12 RuralNet courses also revealed that a lack of classroom access to Internet and lack of resource/technical support at school contributed significantly to lower level of use among noncompleters. 相似文献

Attempts to improve the quality of education in Botswana have, inter alia, included an emphasis on a learner-centered pedagogy. Attempts at implementing this pedagogy have been made within the ambit of the technical rational model of curriculum development. The attempts, however, have produced inconclusive results, and these results have often been rationalized in technicist terms, e.g., as being due to lack of resources and poorly trained teachers. Overlooked in this technicist model are the teachers' perspectives on the innovation. Using the case-study approach within the rubrics of the qualitative research paradigm, this study sought to establish the perspectives of geography teachers in a senior secondary school in Botswana vis-a-vis the learnercentered pedagogy advocated in Education for Kagisano ( Social Harmony ), a report produced by the 1977 Commission on Education. The findings indicated that teachers' classroom practices were influenced by many factors other than technical ones: these included the teachers' assumptions about the nature of knowledge and the ways it ought to be transmitted, their perceptions of students, and the goal of schooling. It also emerged that their assumptions were incongruent with the basic tenets of the learner-centered pedagogy. The findings, then, are an indictment of the technical rational model of change implementation applied in Botswana. They indicate that disregarding what teachers know and think about their taken-for-granted classroom practices when effecting change can lead to disappointing results. 相似文献

This article examines the differences between the formally stated aims of education and the implementation of the school curriculum in order to show the divergence between what is initiated and what emerges as school practice. This implementation problem is examined from the policy-makers' and teachers' perspectives, with specific reference to physical education as a school subject in Hong Kong. First, it examines the existence and intention of educational policy towards curriculum as established by policy-makers. Second, the implementation process is evaluated from the teachers' perspective by employing a framework adopted by Cuban (1998) that utilized effectiveness, popularity, fidelity, adaptability and longevity. The data are derived from a case-study of a physical education programme that included document analysis, and interviews with teachers, parents and students. The case-study provided a subjective perspective of teachers and their work, while the framework assisted in demonstrating the absence of cohesion between the various government agencies. The resulting fragmentation of ideas leading to confusion and frustration for teachers also indicates that longevity and adaptability are likely to be the most constructive criteria for the assessment of curriculum change. 相似文献

In teaching science, the beliefs of teachers may come into conflict and inhibit the implementation of reformed teaching practice.
An experienced biology teacher, Mr. Hobbs, was found to have two different sets of epistemological beliefs while his classroom
practice was predominantly teacher-centered. A case study was then performed in order to investigate the underlying issues
that contributed to his classroom practice. Data sources included preliminary and follow-up interviews and classroom observations.
Data analysis indicated that factors that prevented the epistemological conflict from reaching a resolution included Mr. Hobbs’
beliefs about learning, contextual teaching factors, personal experiences as a student, and views of the nature of science.
The findings from this case indicate that science teachers possess complex belief systems that are not immediately obvious
to either the teacher or science teacher educators, and science teacher educators need to address teacher beliefs when they
encourage teachers to implement reformed teaching practices. 相似文献

The purpose of this study was to investigate the longitudinal application of a suite of curriculum authoring tools (CATs) to inclusive classroom teaching practice in a secondary school setting. The study sought to establish whether the incorporation of the CATs into the teachers’ curriculum development and implementation covaried with improved implementation integrity of classroom teaching practice over time. A repeated measures design was used to establish whether those teachers with high levels of tool use also recorded higher levels of implementation integrity in their use of specific inclusive teaching practices. The effects of the tools were measured using 578 50‐minute classroom observations gathered over a 2.5‐year period. The results indicated that higher levels of implementation integrity in classroom practice covaried with the extent to which the tools were used for the design and implementation of curriculum. 相似文献

The use of problem-solving in science instruction implies a change in the teacher's role from dispensing content information
to encouraging critical reflective thinking in the student. For problem-solving to become an integral part of the science
curriculum, teachers must make it the focus of their instruction. This study investigated the extent to which pre-service
primary teachers used the problem-solving approach in their science instruction. It also identified the factors affecting
their efforts to teach science using this approach. The issues considered are important in whether problem-solving becomes
part of the science curriculum, as teaching behaviour influences student learning outcomes.

Six beginning primary school teachers pioneering the Interactive Teaching approach to science were studied in their first
year of teaching. Interviews with the beginning teachers revcaled that they faced several obstacles to the implementation
of the interactive teaching of science. These included lack of collegial support, lack of feedback on their teaching, difficulty
assessing the learning of their pupils, and the differences between the culture of learning of the alternative science pedagogy
and that of their pupils. By the end of the year, teachers had reconstructed the alternative science pedagogy in ways that
reduced these difficulties. The interviews also provided evidence that ongoing support by teachers and teacher-educators versed
in the alternative pedagogy can make beginning teacher's implementation of the Interactive Teaching of science less difficult.
