Abstract An increasing number of researchers are investigating the effect of students’ prior knowledge and beliefs on their development of scientific concepts. Much of this research is taking place within the framework of constructivism, and is attracting the attention of science educators in non‐western countries. This integrative research review has been undertaken to help researchers and practitioners to identify issues for further investigation and reflection. The results suggest that ‘cosmetic’ attempts to nationalize western science curricula in non‐western countries are likely to prove ineffective because the problem, from the students’ perspective, is one of poor ‘fit’ between their world‐views, language meanings and prior beliefs and those inherent in the subject. A constructivist paradigm seems to offer good prospects for both understanding the problem and formulating learning strategies in science education which are better suited to non‐western cultures. Nevertheless, constructivist pedagogies imported from the West should be examined for their cultural appropriateness. 相似文献

In this paper I consider a role for risk understanding in school science education. Grounds for this role are described in terms of current sociological analyses of the contemporary world as a ‘risk society’ and recent public understanding of science studies where science and risk are concerns commonly linked within the wider community. These concerns connect with support amongst many science educators for the goal of science education for citizenship. From this perspective scientific literacy for decision making on contemporary socioscientific issues is central. I argue that in such decision making, risk understanding has an important role to play. I examine some of the challenges its inclusion in school science presents to science teachers, review previous writing about risk in the science education literature and consider how knowledge about risk might be addressed in school science. I also outline the varying conceptions of risk and suggest some future research directions that would support the inclusion of risk in classroom discussions of socioscientific issues. 相似文献

Background and purpose:?The article reviews studies that focus on the professional development of teachers after they have completed their basic teacher training. Teacher professional development is defined as teachers’ learning: how they learn to learn and how they apply their knowledge in practice to support pupils’ learning. The research question addressed in the article is: How do experienced teachers learn? Main argument:?The review is framed by theories within the constructivist paradigm. From this perspective, knowledge is perceived as the construction of meaning and understanding within social interaction. The social surroundings are seen as decisive for how the individual learns and develops. It is argued that courses and lectures, or ‘times for telling’, and teachers’ development of a metacognitive attitude are decisive factors for teachers’ learning within a constructivist frame of reference. Sources of evidence and method:?To attempt to answer the research question, a search was conducted of the subject of pedagogy in the ISI WEB of Science (search undertaken 9 August 2011) using the search strings ‘teacher learning’, ‘teacher development’ and ‘teacher professional development’, and covering the period from 2009 to 2011 to probe the most recent decade of research. Articles that dealt with basic education, primary and secondary school, were selected, and articles that dealt with learning using digital tools and the internet and newly trained teachers were rejected. A set of 31 articles was selected from this search. To ensure width and depth of coverage, this was supplemented by a selection of review studies and research on further education in respect of teachers’ learning. The texts were analysed by means of open and axial coding, developing main and sub-categories. Conclusions:?The review of articles shows that both individual and organisational factors impact teachers’ learning. Teacher co-operation has importance for how they develop, and some of the teachers can lead such learning activities themselves. Moreover, a positive school culture with a good atmosphere and understanding of teachers’ learning, in addition to co-operation with external resource persons, may impact the professional development of teachers. The article concludes with the reflection that learning in school is the best arena for further development of teachers. 相似文献

A previous study highlighted the perception among secondary science teachers that they faced considerable challenges to their pedagogical practice when teaching unfamiliar areas of the curriculum; for example, when teaching out of subject specialism. One of the major challenges cited by the teachers was being able to give appropriate and effective science teaching explanations in the classroom. Since talking in order to explain science is at the centre of what science teachers do, this concern is a significant one for teacher educators. This article considers some of the methodological issues about how to investigate the relationship between teachers’ subject content knowledge and their pedagogical practice. The research outlined focuses on a single science teacher’s practice in giving science teaching explanations when teaching in and out of subject specialism. Although the findings from a single case are of limited value in terms of generalisability, this study adds to the discussion about future research into the relationship between teachers’ professional knowledge bases and their pedagogical practices. 相似文献

The challenge of preparing students for the information age has prompted administrators to increase technology in the public schools. Yet despite the increased availability of technology in schools, few teachers are integrating technology for instructional purposes. Preservice teachers must be equipped with adequate content knowledge of technology to create an advantageous learning experience in science classrooms. To understand preservice teachers’ conceptions of technology integration, this research study explored 15 elementary science methods students’ definitions of technology and their attitudes toward incorporating technology into their teaching. The phenomenological study took place in a science methods course that was based on a constructivist approach to teaching and learning science through science activities and class discussions, with an emphasis on a teacher beliefs framework. Data were collected throughout the semester, including an open-ended pre/post-technology integration survey, lesson plans, and reflections on activities conducted throughout the course. Through a qualitative analysis, we identified improvements in students’ technology definitions, increased technology incorporation into science lesson plans, and favorable attitudes toward technology integration in science teaching after instruction. This research project demonstrates that positive changes in beliefs and behaviors relating to technology integration in science instruction among preservice teachers are possible through explicit instruction. 相似文献

Whilst there is general agreement that primary teachers have a rather limited understanding of science, as Symington and Mackay
(Note 1) have shown there is no universally accepted view amongst teacher educators in Victoria about the steps that need
to be taken to improve their subject matter competence in science. This paper addresses the issue by taking a topic which
is widely included in primary science programs, namely floating and sinking, and asking what knowledge primary teachers should
have to enable them to handle the topic in a primary classroom in a way consistent with constructivist ideas. The paper will
also address the issue of how that knowledge could be assessed.

In this article we problematize the purpose of teaching science in preschool and the competences preschool teachers need in order to conduct science activities in the classroom. The empirical data were collected through an action research project with five preschool and primary school teachers (K-6). In the first section of this paper we use one situation, a floating–sinking experiment, as an illustration of how two different epistemological perspectives generate different foci on which kind of science teaching competences can be fruitful in preschool settings. In the first perspective, the central goal of science teaching is the development of the children’s conceptual understanding. With this perspective, we found that the science activities with children were unsuccessful, because their thoughts about concepts did not develop as expected, the situation even enhanced a “misconception” concerning density. Moreover, the teacher was unsuccessful in supporting the children’s conceptual learning. The second perspective uses a feminist approach that scrutinizes science, where we investigate if the floating–sinking activity contributes to a feeling of participation in a scientific context for the children and if so how the teacher promotes this inclusion. This second perspective showed that the children’s scientific proficiency benefited from the situation; they had a positive experience with density which was reinforced by the teacher. The children discovered that they had power over their own learning by using an experimental approach. On the basis of these findings, we conclude that there are competences other than subject matter knowledge that are also important when preschool teachers engage children in scientific activities. Through process-oriented work with the teacher group, we identified four concrete skills: paying attention to and using children’s previous experiences; capturing unexpected things that happen at the moment they occur; asking questions that challenge the children and that stimulate further investigation; creating a situated presence, that is, “remaining” in the situation and listening to the children and their explanations. We discuss possible ways to move preschool teachers away from their feelings of inadequacy and poor self-confidence in teaching science by reinforcing this kind of pedagogical content knowledge. 相似文献

Pedagogical content knowledge (PCK) is a type of teacher knowledge to be developed by a teacher. PCK is said to contribute to effective teaching. Most studies investigated the development of PCK and its influence on students’ learning from the teachers’ perspectives. Only a limited number of studies have investigated the components of science teachers’ PCK that helped students’ learning from the perspective of students. Thus, it is the aim of this study to investigate the level of science teachers’ PCK from students’ perspective, in particular whether or not students of different achieving ability had different views of teachers’ PCK in assisting their learning and understanding. Based on the PCK research literature, six components of PCK have been identified, which were as follows: (1) subject matter knowledge, (2) knowledge of teaching strategies, (3) knowledge of concept representation, (4) knowledge of teaching context, (5) knowledge of students, and (6) knowledge of assessment in learning science. A questionnaire consisting of 56 items on a five-point Likert-type scale were used for data collection from 316 Form Four students (16 years old). One-way analysis of variance revealed that the differences in science teachers’ PCK identified by students of different achieving abilities were statistically significant. Overall, students of various academic achieving abilities considered all the components of PCK as important. The low-achieving students viewed all the components of PCK as being less important compared to the high and moderate achievers. In particular, low-achieving students do not view ‘knowledge of concept representation’ as important for effective teaching. They valued the fact that teachers should be alert to their needs, such as being sensitive to students’ reactions and preparing additional learning materials. This study has revealed that PCK of science teachers should be different for high and low-achieving students and knowledge of students’ understanding plays a critical role in shaping teachers PCK. 相似文献

Little change has been noted over 10 years of research into teacher knowledge and confidence to teach science in the early and primary years of schooling. There is a significant body of research demonstrating that early childhood and primary teachers lack confidence and competence in teaching science. However, much of this research blames the victim, and offers little analysis for the systemic reasons for teachers’ confidence and competence in science education other than a lack of science knowledge. This paper reports on a study that examined teacher philosophy and pedagogical practices within the context of an analysis of children’s concept formation within playful early childhood settings. Through teacher interviews, video recordings of science play, and photographic documentation of children’s science activities in one rural preschool, it was noted that teacher philosophy about how young children learn is a significant contributing factor to learning in science. It is argued that teacher philosophy makes more of a difference to children’s scientific learning than does teacher confidence to teach science or knowledge of science. The study also shows that without a mediational scientific framework for using materials in play‐based contexts, children will generate their own imaginary, often non‐scientific, narratives for making sense of the materials provided. 相似文献

This research investigates the role of experience in relation to teachers’ beliefs and practices. The study adopted a social‐cultural constructivist perspective using an interpretive approach. The research was guided by teachers’ interpretations of their experiences related to teaching science through Science‐Technology‐Society (STS) issues. These interpretations are re‐interpreted to find meaningful conceptual categories (grounded in the data) from which to build a model to understand the influence of experiences within socio‐Islamic culture on teachers’ beliefs and practices. Data was collected from ten teachers using interviews and observations. The findings of this study suggest that it was mainly teachers’ personal religious beliefs and experiences that shaped their beliefs and practices. The research also led to a model, constructed on the basis of the data analysis, which suggests an explanation of how teachers’ personal religious beliefs and experiences influence their beliefs and practices. 相似文献

Models play an important role in science education. However, previous research has revealed that science teachers’ content knowledge, curricular knowledge, and pedagogical content knowledge on models and modelling are often incomplete or inadequate. From this perspective, a research project was designed which aimed at the development of beginning science teachers’ knowledge in this domain. In this project, the Interconnected Model of Teacher Professional Growth [Clarke, D., & Hollingsworth, H. (2002). Teaching and Teacher Education, 18(8), 947–967] was used as the basic framework for the establishment of the relationships between the different data gathered in characterising teachers’ knowledge on models and modelling. In this paper, the whole framework of the research is presented, as is some evidence of how powerful this framework was in helping us to understand the development of the teachers’ knowledge. 相似文献

Constructivism in School Science Education: Powerful Model or the Most Dangerous Intellectual Tendency? 总被引：1，自引：0，他引：1
This paper explores and challenges a numberof the assumptions and claims commonly associated with a constructivist approach to school scienceeducation, e.g., that constructivist ideas aboutlearning require a progressive pedagogy or that`active learning' demands engaging students withpractical activities. It suggests that constructivistideas have a particular appeal within primaryeducation because they help to justify classroompractices and activities that primary school teachers,for a variety of other reasons, regard as important.It is suggested that the recent dominant emphasis uponconstructivism in science education has narrowed boththe professional and the research agenda relating toschool science teaching. The paper argues for greaterclarity and precision when referring to constructivistideas in science education and for a betterunderstanding of the role that learning theoriesshould play in influencing the ways in which scienceis taught in schools. 相似文献

In this study, I, the first author as a Thai teacher educator employed self-study as a research methodology to investigate my own understandings, questions, and curiosities about pedagogical content knowledge (PCK) for teaching science student teachers and the ways I engaged student teachers in a field-based science methods course designed to help them to develop their PCK. Qualitative data gathered included: the syllabi, handouts, work submitted by student teachers, student teachers’ journal entries, my journal entries, and video recordings of my classroom teaching. Data were analysed using an inductive process to identify ways in which I attempted to enhance student teachers’ PCK. The contributions of this study are insights generated to help teacher educators think about how to support and develop student teachers’ PCK. Some of these contributions are enhancing teacher educators’ PCK for teaching science teachers, developing PCK for teaching science, and designing a science methods course in science teacher preparation programmes. 相似文献

建构主义对科学教育理论的贡献与局限 总被引：33，自引：0，他引：33
建构主义在教育上的贡献主要在于在教育思想上进一步强调了认知主体的主动性 ,在科学教育上指出了科学知识学习的困难性。但激进的建构主义认识论和方法论在根本上有悖于科学理性 ,将认知主体的主动性和科学学习的困难性夸大为科学知识不可传授 ,这给教育研究和实践带来了混乱。在我国进行科学教育理论探索和实践的过程中 ,在应用建构主义原理发展学生的自主性的同时 ,应注意防止激进的建构主义的负面影响 相似文献

Given the increasing diversity of the student body, teachers are called to appropriately address students’ various learning needs by means of differentiated instruction (DI). However, empirical research has yielded mixed evidence on teachers’ reported use of DI. Using nationally representative data from the National Educational Panel Study in Germany, this article aimed to explore German (as native language) and Mathematics teachers’ use of DI practices. In addition, this study took into consideration contextual factors, such as school track, and investigated the impact of teachers’ constructivist beliefs on their DI implementation. Results from a mixed analysis of covariance indicated that teachers occasionally implement DI practices. Furthermore, between‐subject effects reported differences across school tracks. It appears that advanced secondary school teachers implement less often DI practices. The covariate of teachers’ constructivist beliefs was also positively linked to overall teachers’ implementation of DI. Implications of the results, as well as further lines of research are discussed. 相似文献

This paper reports the relationship between four English primary teachers’ understanding of the nature of science and their practice. Action research was included as a major part of the research design in order to explore the dialectical interplay between various factors at work in the teachers’ practice. The influences of both tacit and espoused understandings of the nature of science were considered alongside the teachers’ beliefs about education, teaching, and learning. These beliefs were found to be the determining factor in the teachers’ decisions about classroom strategies. In arguing for a dialectical perspective on teachers’ practice, the research suggests that teachers’ espoused understanding of the nature of science may also be at least partially formed by the influence of these beliefs, raising the possibility that influence may run from teaching to theoretical understanding and not the other way round. 相似文献

The subject knowledge primary teachers have as a basis for their teaching of science has become a major concern in preservice
and inservice education in many countries, including Australia, the UK and the USA. There are differing views among policy
makers, teacher educators and student teachers about precisely what primary teachers need to know and how they are best prepared
for teaching science. This article reports an investigation into the science content and pedagogic content knowledge of student
teachers a university in the UK. Many students said that when approaching a real teaching situation they would be able to
prepare themselves adequately by independent research using published sources. The data from this study revealed that half
the group of students were able to do so with guidance although their initial background knowledge of science was weak. Implications
for the preparation of primary student teachers are discussed. 相似文献

This study focused on my use of first grade literacy cases to scaffold a diverse constructivist perspective in my literacy methods course for preservice teachers. The cases depicted my concurrent work in a local school with three underachieving readers, two having diverse backgrounds with respect to home languages and socioeconomic status. I examined how I communicated a diverse constructivist orientation through cases, and whether preservice teachers utilized this perspective in their assignments. Qualitative analyses of university course videotapes and preservice teachers’ assignments revealed that over time many preservice teachers showed beginning attempts at articulating a diverse constructivist orientation when assignments focused on actual students. 相似文献

Knowing the subject matter of a secondary‐school science subject 总被引：1，自引：1，他引：0

This paper examines the fundamental yet largely neglected distinction between school subjects and academic disciplines in the discourse on teachers’ specialized subject‐matter knowledge. It analyses and critiques the curricular positions embedded in that discourse in the light of five possible relationships between school subjects and academic disciplines. Invoking Dewey’s logical‐psychological distinction and research findings, the paper argues that the subject matter of a secondary‐school science subject instead of the subject matter of its parent academic discipline lies at the heart of secondary‐school science teachers’ specialized subject‐matter knowledge. Knowing such subject matter entails knowing five intersecting dimensions: the logical, the psychological, the pedagogical, the epistemological, and the sociocultural. Implications are drawn concerning theorizing about what secondary‐school science teachers need to know about the subject matter they are expected to teach, subject‐matter preparation for teaching, and the development of secondary‐school science curriculum materials. 相似文献
