Developing pre-service science teachers’ epistemic insight remains a challenge, despite decades of research in related bodies of work such as the nature of science (NOS) in science education. While there may be numerous aspects to this problem, one critical element is that the NOS is a meta-concept that demands higher-order cognitive skills. One possible strategy to facilitate pre-service teachers’ understanding of epistemic aspects of science is visualisation. Visual representations of objects and processes can be tools for developing and monitoring understanding. Although the NOS and visualisation literatures have been studied extensively, the intersection of these bodies of literatures has been minimal. Incorporating visual tools on the NOS in teacher education is likely to facilitate teachers’ learning, eventually impacting their students’ learning of the NOS. The objective of this paper is to illustrate how the visual tools of scientific knowledge and practices aspects of the NOS can be integrated in science teacher education in order to develop pre-service teachers’ epistemic insight. The paper presents an empirical study that incorporated visual tools about the NOS in primary science teacher education. Data on 14 pre-service teachers’ are presented along with in-depth case studies of 3 pre-service teachers illustrating the influence of the teacher education intervention. The qualitative analysis of visual representations before and after the intervention as well as verbal data suggests that there was improvement in pre-service teachers’ perceptions of the NOS. Implications for future research on visualisation of the NOS are discussed.  相似文献

A recent framework on nature of science (NOS) is the Family Resemblance Approach (FRA). FRA presents NOS as a cognitive-epistemic and social-institutional system with a set of categories: aims and values, scientific methods, scientific practices, scientific knowledge and social-institutional aspects of science. Although FRA has been problematised philosophically and its implications for science education have been considered by science educators, its empirical adaptations in science education are limited. In order to illustrate the educational adaptations of FRA, we refer to Reconceptualised Family Resemblance Approach to Nature of Science or RFN. We present a study based on a funded pre-service science teacher education project whose aim was to design, implement and evaluate the impact of RFN strategies. Fifteen pre-service teachers participated in a 14-week teacher education intervention that infused RFN. A 70-item questionnaire was designed to investigate the outcomes of the teacher education intervention. Individual interviews with pre-service teachers were also conducted. Quantitative and qualitative data analysis suggest that the teacher education intervention had an overall significant impact on pre-service teachers’ views of NOS. The paper contributes to the understanding of how NOS can be incorporated in science teacher education using a new orientation to NOS based on FRA.  相似文献

The aim of this exploratory, longitudinal study was to describe an overall picture of how perceptions of the teacher role and attitudes toward science and science teaching develop and interact during preschool teacher education, and how this in turn influences behavior when students are engaged in teaching science. Sixty-five students enrolled in a preschool teacher education program at a Swedish university were followed throughout their teacher education. The study used a phenomenographic approach within a theoretical framework of sociocultural and situated learning perspective. Questionnaires with open and closed questions were combined with interviews. The results show that in spite of growing competence and confidence, many of the students still found science activities to be awkward in preschool, mainly due to a wish to protect the children from school culture. The results have implications for teacher education and the preschool community, showing a need to problematize the purpose of teaching science in preschool and the meaning of pedagogical content knowledge in this context.  相似文献

A shortage of qualified science teachers has been recognized as a serious problem in the field of education in many countries. Taiwan, however, has successfully recruited graduate-level science students into teaching through newly established teacher education programs at universities in recent years. This study seeks to examine why such students are motivated for entry into teaching. In-depth interviews of 33 graduate science students from one teacher education program and a survey of 101 students from nine teacher education programs at universities in Taiwan were conducted. Results show that these students were attracted to teaching by an early exposure to science teaching in informal settings and their perceptions of handsome material rewards, favorable working conditions, and relatively high social status of teaching. The cultural roots of these factors are discussed; implications and limitations of the results are suggested.  相似文献

In this article, the argument is put forth that controversies about the scope and limits of science should be considered in Nature of Science (NOS) teaching. Reference disciplines for teaching NOS are disciplines, which reflect upon science, like philosophy of science, history of science, and sociology of science. The culture of these disciplines is characterized by controversy rather than unified textbook knowledge. There is common agreement among educators of the arts and humanities that controversies in the reference disciplines should be represented in education. To teach NOS means to adopt a reflexive perspective on science. Therefore, we suggest that controversies within and between the reference disciplines are relevant for NOS teaching and not only the NOS but about NOS should be taught, too. We address the objections that teaching about NOS is irrelevant for real life and too demanding for students. First, we argue that science-reflexive meta-discourses are relevant for students as future citizens because the discourses occur publicly in the context of sociopolitical disputes. Second, we argue that it is in fact necessary to reduce the complexity of the above-mentioned discourses and that this is indeed possible, as it has been done with other reflexive elements in science education. In analogy to the German construct Bewertungskompetenz (which means the competency to make informed ethical decisions in scientific contexts), we suggest epistemic competency as a goal for NOS teaching. In order to do so, science-reflexive controversies must be simplified and attitudes toward science must be considered. Discourse on the scientific status of potential pseudoscience may serve as an authentic and relevant context for teaching the controversial nature of reflexion on science.  相似文献

Research into student teachers’ perceptions, attitudes and prior experiences of learning suggests that these experiences can exert an influence on practice which can be relatively undisturbed by their initial teacher education. This article is based on the initial findings of an all-Ireland survey of all first-year students on B.Ed. courses in colleges in Northern Ireland and in the Republic of Ireland. The survey is the first stage in a longitudinal study which will follow the same cohort of students for the duration of their initial teacher education, seeking to map and track the development of their ideas about teaching and learning in primary history, geography and science. Based on an analysis of the quantitative data in the entry questionnaire, the initial findings suggest that subject knowledge remains a problematic issue in initial teacher education and that both location and gender interact with knowledge, attitudes and subject area to produce a complex and challenging context for teacher educators in history, geography and science education.  相似文献

Over the last two decades, science educators and science education researchers have grown increasingly interested in utilising insights from the sociology of scientific knowledge (SSK) to inform their work and research. To date, researchers in science education have focused on two applications: results of sociological studies of science have been used to define new areas of content, generally referred to as Nature of Science (NOS). This has included research into students’ understanding of the NOS, teachers’ understanding of the NOS, and inclusion (or exclusion) of NOS themes in curricula. A second vein of inquiry has been investigations that consider the classroom as a microcosm of scientific discourse and inquiry. Such research has included investigations of student‐to‐student and student‐to‐teacher interactions. In this paper, we present a third application for educational research – the investigation of teacher knowledge and practice as sociological phenomena. In addition to supporting scholarly research, we believe it can be a useful tool for illuminating the complexities of teaching that needs to be taken into account by policy makers and practitioners. In this paper, we provide a thematic review of concepts from the sociology of scientific knowledge, and their application to a case of teacher work.  相似文献

While teacher educators have had some success in helping prospective teachers understand the nature of science (NOS), they have been less effective in helping prospective teachers teach NOS. Though several studies have alluded to impacts of various interventions on developing pedagogical content knowledge (PCK) for NOS, the nature, source, and development of PCK for NOS has not yet been investigated in any systematic way. This study addresses that gap by identifying critical incidents in the development of PCK for NOS of a prospective elementary teacher as she transitions from her methods course to student teaching. Analysis of data collected over a 2-year period illuminates pedagogical dilemmas faced by the prospective teacher in enacting NOS instruction within a school culture of primarily “traditional” science teaching. Through construction of critical incident vignettes, narrative inquiry is employed to illustrate the changes in her PCK for NOS over time, and the experiences that facilitated these changes. Implications for supporting the development of PCK for NOS within teacher education are discussed.  相似文献

A number of science education policy documents recommend that students develop an understanding of the enterprise of science and the nature of science (NOS). Despite this emphasis, there is still a gap between policy and practice. Teacher professional literature provides one potential venue for bridging this gap, by providing “activities that work” (Appleton in elementary science teacher education: International perspectives on contemporary issues and practice. Lawrence Erlbaum Associates, Mahwah, NJ, 2006) that can scaffold teachers’ developing pedagogical content knowledge (PCK) for teaching NOS. We analyzed articles published in the NSTA journal The Science Teacher (1995–2010) in terms of the degree to which they provide appropriate model activities and specific information that can support the development of teachers’ PCK for teaching NOS. Our analysis revealed a diversity of NOS aspects addressed by the authors and a wide range of variation in the percent of articles focused on each aspect. Additionally, we found that few articles provided robust information related to all the component knowledge bases of PCK for NOS. In particular, within the extant practitioner literature, there are few models for teaching the aspects of NOS, such as the function and nature of scientific theory. Furthermore, though articles provided information relevant to informing teachers’ knowledge of instructional strategies for NOS, relevant information to inform teachers’ knowledge of assessment in this regard was lacking. We provide recommendations for ways in which the practitioner literature may support teachers’ teaching of NOS through more robust attention to the types of knowledge research indicates are needed in order to teaching NOS effectively.  相似文献

The nature of science (NOS) has become a central goal of science education in many countries. This study sought an understanding of the extent to which a nature of science course (NOSC), designed according to the conceptualization of pedagogical content knowledge (PCK) for teaching nature of science (NOS), affects in-service science teachers’ understanding and learning of NOS, and their orientations towards teaching it. A qualitative research approach was employed as a research methodology, drawing upon pre- and post-instruction NOS questionnaires, field notes, and in-service teachers’ weekly journal entries and assignments. Open-ended NOS questionnaires, used to assess participants’ understandings of NOS, were analysed and categorized as either informed, partially informed and naive. Other qualitative data were analysed through an inductive process to identify ways in-service teachers engaged and learned in the NOSC. The results indicate that at the beginning of the course, a majority of the in-service science teachers held naive understandings of NOS, particularly with respect to the definition of science, scientific inquiry, and differences between laws and theories. They viewed implicit project-based science and science process skills as goals of NOS instruction. By engaging in the course, the in-service science teachers developed an understanding of NOS and orientations to teaching NOS based on various elements, especially reflective and explicit instruction, role modelling, and content- and non-content embedded instruction. The aim of this study is to help science teacher educators, consider how to support and develop science teachers’ understandings of NOS while being mindful of PCK for NOS, and develop methods for teaching NOS frameworks.  相似文献

The current study addresses student perceptions of math and science professors in the Middle East. Gender disparity in science, technology, engineering, and math (STEM) education continues to exist in higher education, with male professors holding a normative position. This disparity can also be seen in the United Arab Emirates. As female participation in STEM education lags behind men, it is possible that gender stereotypes may influence students’ first impressions of male and female instructors. The United Arab Emirates provides a unique context to study this phenomenon as it is a traditional patriarchal society that is highly dependent on the engineering discipline, especially within the oil and gas sectors. A total of 176 undergraduate students from 2 universities in the United Arab Emirates completed a survey about teaching effectiveness based on their perceptions of photographs of hypothetical male and female instructors. A factor analysis of survey items revealed 2 main subcategories of teacher effectiveness: namely teacher warmth and professionalism. A 2-way between-groups analysis of variance was conducted to explore the impact of teacher gender and student gender on perceptions of overall teaching effectiveness, as well as their perceptions of teacher warmth and professionalism. Findings revealed that there was a significant cross-gender effect on student perceptions of math and science instructors in the United Arab Emirates.  相似文献

This paper reports a 4-month study that investigated the effectiveness of curriculum materials incorporating the history of science (HOS) on learning science, understanding the nature of science (NOS), and students’ interest in science. With regards to these objectives, three different class contexts were developed with three main types of information in history of science. In the first class context, the similarities between students’ alternative ideas and scientific concepts from the HOS were considered in developing teaching materials. In the second class context, the teacher developed discussion sessions on the ways scientists produce scientific knowledge. In the third class context, short stories about scientists’ personal lives were used without connection to the concepts of science or NOS. Ninety-one eighth-grade students were randomly assigned to four classes taught by the same science teacher. The concepts in the motion unit and in the force unit were taught. Three of the four classrooms were taught using the contexts provided by the HOS while the fourth class was taught in the same way that the teacher had used in previous years. The effects on student meaningful learning, perceptions of the NOS, and interest in science were evaluated at the beginning, at the middle, and at the end of the study to compare differences between historical class contexts and the Traditional Class. Results of analysis showed that the changes in meaningful learning scores for the first class context were higher than other classes but the differences between classes were not significant. The HOS affected student perceptions of the scientific methods and the role of inference in the process of science. Stories from scientists’ personal lives consistently stimulated student interest in science, while discussions of scientific methods without these stories decreased student interest. The positive effects of stories relating scientist’ personal life on student interest in science has major importance for the teaching of science. This research also helps to clarify different class contexts which can be provided with different types and uses of historical information.  相似文献

It is problematic whether primary teachers benefit by completing a first degree especially when the teaching of specific subjects, here science, is the focus of attention. This study reports the comparative results of interviewing thirteen Canadian and ten Australian student teachers, both about to commence their Bachelor of Education. The Canadian students had completed an initial degree while nine of the Australian students were school leavers. The interviews, which explored views about teaching primary science, were analysed with this factor in mind. Student teacher perceptions reported include: how to recognise a “good” primary science teacher; perceptions of self as a “good” primary science teacher; expectations of how the teacher education program could assist their science teaching; and whether (for the Canadian students) the initial degree will help in becoming a primary science teacher. Analysis of the interviews suggests possible influences a first degree (among other factors) may have on perceptions related to primary science teaching and raises questions about what is the best general approach for preparing primary teachers to teach science effectivly.  相似文献

Roussel De Carvalho uses the notion of superdiversity to draw attention to some of the pedagogical implications of teaching science in multicultural schools in cosmopolitan cities such as London. De Carvalho makes the case that if superdiverse classrooms exist then Science Initial Teacher Education has a role to play in helping future science teachers to become more knowledgeable and reflective about how to teach school students with a range of worldviews and religious beliefs. The aim of this paper is to take that proposition a step further by considering what the aims and content of a session in teacher education might be. The focus is on helping future teachers develop strategies to teach school students to think critically about the nature of science and what it means to have a scientific worldview. The paper draws on data gathered during an interview study with 28 students at five secondary schools in England. The data was analysed to discover students’ perceptions of science and their perceptions of the way that science responds to big questions about being human. The findings are used to inform a set of three strategies that teachers could use to help young people progress in their understanding of the nature of science. These strategies together with the conceptual framework that underpins them are used to develop a perspective on what kinds of pedagogical content knowledge teacher education might usefully provide.  相似文献

Reading the interesting article Discerning selective traditions in science education by Per Sund, which is published in this issue of CSSE, allows us to open the discussion on procedures for teaching science today. Clearly there is overlap between the teaching of science and other areas of knowledge. However, we must constantly develop new methods to teach and differentiate between science education and teaching science in response to the changing needs of our students, and we must analyze what role teachers and teacher educators play in both. We must continually examine the methods and concepts involved in developing pedagogical content knowledge in science teachers. Otherwise, the possibility that these routines, based on subjective traditions, prevent emerging processes of educational innovation. Modern science is an enormous field of knowledge in its own right, which is made more expansive when examined within the context of its place in society. We propose the need to design educative interactions around situations that involve science and society. Science education must provide students with all four dimensions of the cognitive process: factual knowledge, conceptual knowledge, procedural knowledge, and metacognitive knowledge. We can observe in classrooms at all levels of education that students understand the concepts better when they have the opportunity to apply the scientific knowledge in a personally relevant way. When students find value in practical exercises and they are provided opportunities to reinterpret their experiences, greater learning gains are achieved. In this sense, a key aspect of educational innovation is the change in teaching methodology. We need new tools to respond to new problems. A shift in teacher education is needed to realize the rewards of situating science questions in a societal context and opening classroom doors to active methodologies in science education to promote meaningful learning through meaningful teaching.  相似文献

As part of a longitudinal research study started in 1984, the purpose of this paper is to critically examine the issue of quality in an Integrated Rural Development project in Sierra Leone. An in-depth study was conducted (1990-93) to assess pre-service teacher quality, using two major indices: teacher knowledge base of subject-matter and teacher beliefs about teaching and classroom management. The results indicate that quality is affected by what knowledge teachers possess in a given subject area and their perceptions of teaching. This research is a departure from the traditional areas of looking at quality in education, that is from what happens to students in the education process to the issue of the quality of education teachers receive during their training.  相似文献

This study reports the participation of 13 secondary science teachers in informal support networks and how that participation was associated with their nature of science (NOS) teaching practices 2 to 5 years after having graduated from the same science teacher education program. The nine teachers who participated in informal support networks taught the NOS at high/medium levels, while the four non-participating teachers taught the NOS at low levels. The nine high/medium NOS implementation teachers credited the informal support networks for maintaining/heightening their sense of responsibility for teaching NOS and for helping them navigate institutional constraints that impede effective NOS instruction. Several high/medium NOS instruction implementers initially struggled to autonomously frame and resolve the complexities experienced in schools and thus drew from the support networks to engage in more sophisticated forms of teacher decision-making. In contrast, the NOS pedagogical decisions of the four teachers not participating in support networks were governed primarily by the expectations and constraints experienced in their schools. Implications of this study include the need for reconsidering the structure of teacher mentorship programs to ensure they do not promote archaic science teaching practices that are at odds with reform efforts in science education.

There has been renewed debate in recent years about the relatively poor science discipline background knowledge of primary and preschool teachers, and their lack of confidence to teach science stemming from this. A reaction from teacher educators, such as recommended by theDiscipline Review of Teacher Education in Mathematics and Science Report, has been to provide more explicit science discipline units in pre-service teacher education courses. However, a few studies have cast some doubt on the notion that more science discipline studies (Skamp, 1989; Stepans & McCormack, 1985). This paper reports on pre-service students' perceptions of their cofidence to teach science before and after a science education unit adapted from the PECSTEP work (Kirkwood, Bearlin & Hardy, 1989), which included only a small amount of physical science, and took an explicit gender approach emphasising the students as learners. Specializations: primary teacher education, teaching strategies in science.  相似文献
