An analysis of recent science education research on student conceptions of natural phenomena, on science teaching and on science teacher planning carries implications for science teacher education. This suggests that the development of appropriate conceptions of teaching should be an important goal of science teacher education. Drawing the analogy between conceptions of natural phenomena and conceptions of teaching suggests guidelines for designing instruction in science teacher education courses. The importance of these guidelines is enhanced because teachers are likely to hold conceptions of teaching which are in conflict with those considered appropriate. Activities in science teacher education which have attempted to identify and influence conceptions of science teaching are described and analysed. While these activities must be regarded as preliminary, they point to a powerful approach to thinking about the education of science teachers. 相似文献

Although there is growing interest in studies of teachers' actions and conceptions, little is known about content-related teaching problems arising in science classrooms. This article presents a case study of problems which can occur when teaching the topic of redox reactions to Grade 11 students. Two chemistry teachers, a senior and a junior teacher, were involved in the study. Their reflective comments on the teaching problems were also investigated. Research data were obtained from classroom observations and audiotaped recordings of classroom practice. After the lessons, we conducted semistructured interviews with the teachers. The teaching problems are reported in terms of teaching activities causing difficulties for students in considering new conceptions to be necessary, intelligible, plausible, or fruitful. Analyses of the teachers' comments on these teaching activities clarifies a number of reasons why they acted as they did. It can be concluded that teachers' scientific expertise is an important source of difficulties when teaching redox reactions. Implications for an improvement of current chemistry classroom practice and content-related teacher training are offered. 相似文献

The results are described of two case studies on the conceptions and classroom practice of two Portuguese physics and chemistry teachers on the role of problem solving in the teaching/learning of science. One of these teachers was a novice and the other had about 20 years of teaching experience. The data were obtained from a questionnaire, a semi-structured interview, classroom observation, personal documents, and stimulated recall. The analysis was carried out with instruments organised into categories and specific indicators. The results showed there to be major differences between the intention behind the new curricula, the teachers' conceptions, and their practice. Some suggestions are put forward on the basis of these results for the initial and ongoing education of secondary education teachers of physics and chemistry in Portugal. 相似文献

A sociocultural perspective on teacher learning was used to investigate how three beginning teachers’ conceptions of classroom management affected their developing teaching practices. Students were followed from student teaching through their first 2 years of teaching. Data sources included interviews, classroom observations, and teacher education portfolios. Although all three teachers shared common conceptions of management as establishing positive learning environments, only two of the teachers were successful in doing so. Four key ideas shared by these two teachers served as pedagogical tools that framed their decision-making and scaffolded their early practice. These four conceptions are linked to a course on classroom management not taken by the third teacher. Implications of these findings for teacher education are discussed. 相似文献

Increasingly, instructional improvement efforts include teacher communities as part of their overall strategy, yet the relationship between teachers’ talk and professional learning remains underspecified. Using a discourse perspective on learning, this article compares opportunities to learn (OTLs) in the collaborative conversations of 3 mathematics teacher workgroups. We examined the differences in OTLs in 17 hr of videotaped meetings from 3 groups at different levels of instructional accomplishment in secondary mathematics. Using mixed methods, we uncovered differences in the groups’ interactions and found that OTLs were not equally distributed. Instead, teacher groups whose active participants demonstrated the greatest facility with ambitious instruction also had the richest conversational OTLs. We interpret this as an accumulated advantage developmental story: Because collaborative work in teaching involves problem posing and the articulation of practice, teachers’ conceptions get built into the framing and discussion of pedagogical problems. Accomplished teachers are thus positioned to learn more from talking with colleagues. This analysis contributes to understanding of how OTLs are constituted in teacher workgroups, with implications for making better use of teacher collaboration for professional learning. 相似文献

A CD-ROM consisting of videos of two lessons by different teachers demonstrating exemplary science teaching was used to elicit,
develop and track the changing conceptions of good science teaching of student teachers enrolled for the one-year Postgraduate
Diploma in Education (PGDE) at several stages during the programme. It was found that the videos acted as an effective probe
to elicit student teachers’ conceptions and had significant impact on those conceptions at different stages of the programme
through the provision of teacher models demonstrating exemplary teaching. The experience has extended novice teachers’ awareness
of alternative teaching methods and approaches not experienced in their own schooling, broadened their awareness of different
classroom situations, provided proof of existence of good practices and prompted them to reflect on their current conceptions
of good science teaching. Most importantly, the strategy of asking student teachers to watch the same videos on three separate
occasions at different times of the course was recognized by them as a crucial element in facilitating their reflection on
their changing conceptions of good science teaching.
PGDE is the standard form of pre-service teacher education in Hong Kong. It provides qualified teacher status within Hong
Kong. Student teachers enrolled for the PGDE have completed a relevant undergraduate degree. 相似文献

This is a longitudinal study of the thinking about teaching science of beginning Hong Kong primary teachers. The research explores how their thinking changed from pre-service teacher education through to their first year as classroom teachers. It takes a more holistic view of teacher thinking than typical in the literature considering the nature, interrelationships, and changes over time of four major aspects: conceptions, planning, teaching, and reflection. Positive findings were that the majority of participants became more constructivist in terms of their conceptions and practice of teaching, but they also tended to become more simplistic in planning and less coherent in thinking as they progressed from pre-service teacher education to beginning teachers in schools. 相似文献

Drawing from the phenomenographic perspective, this study investigated Chinese science teacher educators’ conceptions of teaching nature of science (NOS) to preservice science teachers through two semi-structured interviews. The subjects were twenty-four science teacher educators in the developed regions in China. Five key dimensions emerged from the data on the conceptions of teaching NOS, including value of teaching NOS, NOS content to be taught, incorporation of NOS instruction in courses, learning of NOS, and role of the teacher. While some of these dimensions share much similarity with those reported in the studies of conceptions of teaching in general, some are distinctively different, which is embedded in some unique features of teaching NOS to preservice science teachers. These key dimensions can constitute the valuable components of the module or course to train science teachers or teacher educators to teach NOS, provide a framework to interpret the practice of teaching NOS, as well as lay a foundation for probing the conceptions of teaching NOS of other groups of subjects (e.g., school teachers’ conceptions of teaching NOS) or in other contexts (e.g., teaching NOS to in-service teacher). 相似文献

The present article describes research carried out in Badajoz (Spain) with student teachers of Primary and Secondary science education. The preservice teachers conceptions of the nature of science were analyzeda and compared with their classroom practice when teaching a science lesson. The results indicated that there was no correspondence between the conceptions of the nature of science and the classroom practice. The implications of the research for science teacher education are dealt with. 相似文献

How do teachers conceptualize and deal with context of mathematics word problems in their teaching? This question is discussed based on a study of 14 experienced teachers at the elementary, junior high and senior high school levels. Bruner’s notions of paradigmatic and narrative modes of knowing formed the basis of analysis of data from sources that include interviews and classroom observations. The findings highlight the teachers’ conceptions of problem context and teaching approaches for each of these modes of knowing. All of the teachers used the paradigmatic mode in their teaching but with different depth and most engaged in some form of the narrative mode to create a classroom environment that was motivational for students to learn word problems. The paper also highlights characteristics of these two modes as they relate directly to word problems and discusses implications for instruction, learning and teacher development. 相似文献

This study explored practicing elementary school teacher’s conceptions of teaching in ways that foster inquiry-based learning
in the science curriculum (inquiry teaching). The advocacy for inquiry-based learning in contemporary curricula assumes the
principle that students learn in their own way by drawing on direct experience fostered by the teacher. That students should
be able to discover answers themselves through active engagement with new experiences was central to the thinking of eminent
educators such as Pestalozzi, Dewey and Montessori. However, even after many years of research and practice, inquiry learning
as a referent for teaching still struggles to find expression in the average teachers’ pedagogy. This study drew on interview
data from 20 elementary teachers. A phenomenographic analysis revealed three conceptions of teaching for inquiry learning
in science in the elementary years of schooling: (a) The Experience-centered conception where teachers focused on providing
interesting sensory experiences to students; (b) The Problem-centered conception where teachers focused on engaging students
with challenging problems; and (c) The Question-centered conception where teachers focused on helping students to ask and
answer their own questions. Understanding teachers’ conceptions has implications for both the enactment of inquiry teaching
in the classroom as well as the uptake of new teaching behaviors during professional development, with enhanced outcomes for
engaging students in Science. 相似文献

Teacher education programs have adopted preparing science teachers that teach science through inquiry as an important pedagogic
agenda. However, their efforts have not met with much success. While traditional explanations for this failure focus largely
on preservice science teachers’ knowledge, beliefs and conceptions regarding science and science teaching, this conceptual
paper seeks to direct attention toward discursive practices surrounding inquiry science teaching in teacher education programs
for understanding why most science teachers do not teach science through inquiry. The paper offers a theoretical framework
centered on critical notions of subjection and performativity as a much needed perspective on making/becoming of science teachers through participation in discursive practices of science
teacher education programs. It argues that research based on such perspectives have much potential to offer a deeper understanding
of the difficult challenges teacher education programs face in preparing inquiry practicing science teachers. 相似文献

Capitalizing on the comments made by teachers on videos of exemplary science teaching, a video-based survey instrument on the topic of ‘Density’ was developed and used to investigate the conceptions of good science teaching held by 110 teachers and 4,024 year 7 students in Hong Kong. Six dimensions of good science teaching are identified from the 55-item questionnaire, namely, ‘focussing on science learning’, ‘facilitating students’ understanding’, ‘encouraging students’ involvement’, ‘creating conducive environment’, ‘encouraging active experimentation’ and ‘preparing students for exam (PSE)’. Significant gaps between teachers’ and students’ conceptions on certain dimensions have been revealed. The inconsistency on the dimension ‘PSE’ is particularly evident and possible reasons for the phenomenon are suggested. This study raises the important questions of how the gap can be addressed, and who is to change in order to close the gaps. Answers to these questions have huge implications for teacher education and teacher professional development. 相似文献

One strategy for implementing learner-centered teaching is through the preparation of teachers and their induction into the
profession. This article presents case studies of three secondary science teachers that follow them from their science teacher
education program that advocated teaching for conceptual change as one approach to learner-centered teaching into their first
years of teaching. The article’s purpose is to describe the teachers’ initial conceptions of teaching science carried over
from their teacher preparation program, and how they integrated those conceptions with the environmental influences of their
classrooms and schools to produce praxis. Data were collected from the participants in several different ways during the participants’
pre-service year and during their first year or two of teaching: Observation of the participants’ teaching; related interviews
with participants; and their action research journals. As they approached the end of their first or second year of teaching,
all three teachers demonstrated increased levels of confidence in their teaching competence, both in their classroom performance
and their places in their departments and schools. None of them had, however, fully implemented conceptual change teaching
approach that was the specific goal of their teacher preparation program. 相似文献

Several studies have suggested that preservice teacher education has little impact on student teacher conceptions about various
facets of teaching and learning. Most of these studies refer to generic teaching and learning, and very few have related to
primary science in particular. To explore this area eight primary student teachers were interviewed on six occasions during
the first two years of their Bachelor of Teaching degree. This paper reports the findings from part of these interviews. It
describes the (sometimes changing) conceptions which these eight students held about how they would recognise a “good” teacher
of science and the people and experiences they believed influenced the formation of these views. The differential impact of
past and present teachers and the teacher education program revealed possible implications for practica and science curriculum
units in particular, if teacher education is going to have an influence on preservice teachers' conceptions about teaching
and learning. 相似文献

Although teacher-thinking research is now well established, the specific mechanisms through which teachers construct new understandings of their teaching have not been closely examined. This paper presents four interrelated concepts—teachers' conceptions of practice, tensions in their practice, articulation, and local and professional language—which emerged as grounded categories from a longitudinal study of change in teachers' practice. The study focused on how a group of foreign language teachers integrated new ideas, encountered in an inservice masters' degree program, in their thinking about and activity in the classroom. The analysis traced the ways in which the teachers reconstructed their classroom practice, using professional discourse to rename their experience and thus to assign new or different meanings to their actions. The concepts, presented with illustrations from the study and accompanying analysis, have implications for research on teaching and teacher education as well as the design and execution of teacher education programs. 相似文献

AbstractDialogic pedagogy is being promoted in science teacher education but the literature on dialogic pedagogy tends to focus on explicit voices, and so runs the risk of overlooking the important role that material objects often play in science education. In this paper we use the findings of a teacher survey and classroom case study to argue that there is a gap in the way that science teachers think about the role of materials and that this could be addressed by changes in the theory base of teacher training, augmenting the current constructivist and dialogic theory with the addition of new materialism in the form of Barad’s ‘Agential Realism’. Our findings suggests that science teachers do not regularly explicitly consider the relationship between the material resources they deploy and the dialogic learning taking place. We argue that science teacher training and professional development should pay more attention to the material-dialogic relationships in the learning that emerges in science classrooms. 相似文献

Summaries English The report describes a study of the teaching behaviour of student‐teachers of science disciplines during the one‐term teaching practice of the English ‘Post‐Graduate Certificate in Education’ course, using the Science Teaching Observation Schedule by Eggleston et al. The results suggest that in several behavioural dimensions, students and teachers achieve a close match. These dimensions, it is suggested, could represent the ‘stable’ elements in the students’ perception of science teacher behaviour learnt during their time as pupils, or they might represent ‘safe’ transactions which do not involve students extensively in problems of classroom management and control. For other behaviour categories, it was found that students tended to behave less like experienced teachers as the training practice proceeded, but this was to some extent determined by the subject taught. Physics student‐teachers substantially maintained their similarity to experienced teachers, whilst chemistry and biology students drifted away. The nature of these drifts is discussed. 相似文献
