This purpose of this study was to examine the ways in which three prospective teachers who had early opportunities to teach science would approach representing science content within the context of their student teaching experiences. The study is framed in the literature on pedagogical content knowledge and learning to teach. A situated perspective on cognition is applied to better understand the influence of context and the role of the cooperating teacher. The three participants were enrolled in an experimental teacher preparation program designed to enhance the teaching of science at the elementary level. Qualitative case study design guided the collection, organization, and analysis of data. Multiple forms of data associated with student teachers' content representations were collected, including audiotaped planning and reflection interviews, written lesson plans and reflections, and videotaped teaching experiences. Broad analysis categories were developed and refined around the subconstructs of content representation (i.e., knowledge of instructional strategies that promote learning and knowledge of students and their requirements for meaningful science learning). Findings suggest that when prospective teachers are provided with opportunities to apply and reflect substantively on their developing considerations for supporting children's science learning, they are able to maintain a subject matter emphasis. However, in the absence of such opportunities, student teachers abandon their subject matter emphasis, even when they have had extensive background and experiences addressing subject‐specific considerations for teaching and learning. © 2002 Wiley Periodicals, Inc.

Pre‐service teachers face many challenges as they learn to teach in ways that are different from their own educational experiences. Pre‐service teachers often enter teacher education courses with pre‐conceptions about teaching and learning that may or may not be consistent with contemporary learning theory. To build on preservice teachers' prior knowledge, we need to identify the types of views they have when entering teacher education courses and the views they develop throughout these courses. The study reported here focuses specifically on preservice teachers' views of their own students' prior knowledge and the implications these views have on their understanding of the formative assessment process. Sixty‐one preservice teachers were studied from three sections of a science methods course. Results indicate that preservice teachers exhibited a limited number of views about students' prior knowledge. These views tended to privilege either academic or experience‐based concepts for different aspects of formative assessment, in contrast to contemporary perspectives on teaching for understanding. Rather than considering these views as misconceptions, it is argued that it is more useful to consider them as resources for further development of a more flexible concept of formative assessment. Four common views are discussed in detail and applied to science teacher education. © 2008 Wiley Periodicals, Inc. J Res Sci Teach 45: 497–523, 2008  相似文献

This paper presents an analysis of how affordances of ICT‐rich environments identified from a recent review of the research literature can support students in learning science in schools within a proposed framework for pedagogical practice in science education. Furthermore other pedagogical and curriculum innovations in science education (promoting cognitive change, formative assessment and lifelong learning) are examined to see how they may be supported and enhanced by affordances of ICT‐rich environments. The affordances that I have identified support learning through four main effects: promoting cognitive acceleration; enabling a wider range of experience so that students can relate science to their own and other real‐world experiences; increasing students' self‐management; and facilitating data collection and presentation. ICT‐rich environments already provide a range of affordances that have been shown to enable learning of science but integrating these affordances with other pedagogical innovations provides even greater potential for enhancement of students' learning.  相似文献

This paper reports the use of a research‐based, web‐delivered, technology‐and‐science education context (the Generative Virtual Classroom) in which student‐teachers can develop their ability to recognize, describe, analyse and theorize learning. Addressing well‐recognized concerns about narrowly conceived, anachronistic and ineffective technology‐and‐science education, this e‐learning environment aims to use advanced technologies for learning, to bring about larger scale improvement in classroom practice than has so far been effected by direct intervention through teacher education. Student‐teachers' short, intensive engagement with the Generative Virtual Classroom during their practice teaching is examined. Findings affirm the worth of this research‐based e‐learning system for teacher education and the power of a biologically based, generative theory to make sense of the learning that occurred.  相似文献

Technological pedagogical content knowledge TPACK refers to the knowledge set that teachers currently use to further improve the quality of their teaching and assist their students in learning. Several TPACK models have been proposed, either for discussing TPACK's possible composition or its practical applications. Considering that teachers' practical experiences should also be critical to the development of those teachers' knowledge, this study invited a research panel (six researchers) and an expert panel (54 science‐related educators) to propose and validate the framework of TPACK‐practical. After two rounds of anonymous communications that followed Delphi survey techniques, a total of eight dimensions of TPACK‐practical and corresponding indicators were identified and rated as having high levels of importance. Among these knowledge dimensions, the knowledge of direct information and communication technology uses for enhancing teachers' professionalism and students' conceptual comprehension was rated with a high level of importance. Also, disciplinary differences were found to exist between the different groups of experts. Biology teachers showed significantly higher ratings across all knowledge dimensions, whereas physics teachers' ratings were comparatively low. Such findings suggest that the structure and content of subject matter shapes not only the way they teach with technology but also the thinking logics they build longitudinally from their learning experiences.  相似文献

As technology advances, it is important for teachers to seamlessly integrate technology into their innovative teaching techniques. Using virtual worlds is one alternative to traditional teaching methods that can provide rich learning experiences. The purpose of this article is twofold: (a) to present Cotton Island, an avatar‐based 3‐D virtual learning environment in Second Life and (b) to evaluate students’ learning motivation in using Cotton Island as a learning tool. Cotton Island was designed with unique navigational features to provide access to rich resources and educational activities that improve students’ knowledge of cotton. Based on the ARCS (attention, relevance, confidence, and satisfaction) model, this study assesses students’ learning motivation when using Cotton Island as a learning tool, and whether students had a positive learning outcome consistent with the instructors’ goal of knowledge improvement. The results show that students had a positive experience in terms of learning motivation and knowledge improvement.  相似文献

理查德·梅耶是国际公认的多媒体学习研究领域的开拓者和奠基人,其领衔的多媒体学习研究也已形成了由基本假设、学习科学、教学科学和应用领域构成的严谨科学体系。多媒体学习融合了学习科学（认知理论）和教学科学（教学设计）的研究成果,使得学习与教学、理论与实践之间形成了一种互惠关系。这正是多媒体学习研究称之为一门扎根于理论的循证科学的理论特质之体现。从历史的视角来看,在教育研究科学化的历史进程中,首先是学习科学破解了人类学习的理论难题,之后是学习科学向教学科学的转化实践。而多媒体学习研究中的＂化归＂思维在一定程度上使得多媒体学习的理论具有了在学习实践中进行普遍应用的基础性价值。教育技术学要想走向科学化,应该走出追求实用主义的＂寻证＂之路,走向扎根于科学理论基础的＂循证＂之路,同时应该在方法学上寻求突破。  相似文献

What are the barriers to technology‐rich inquiry pedagogy in urban science classrooms, and what kinds of programs and support structures allow these barriers to be overcome? Research on the pedagogical practices within urban classrooms suggests that as a result of many constraints, many urban teachers' practices emphasize directive, controlling teaching, that is, the “pedagogy of poverty” (Haberman, 1991 ), rather than the facilitation of students' ownership and control over their learning, as advocated in inquiry science. On balance, research programs that advocate standards‐based or inquiry teaching pedagogies demonstrate strong learning outcomes by urban students. This study tracked classroom research on a technology‐rich inquiry weather program with six urban science teachers. The teachers implemented this program in coordination with a district‐wide middle school science reform. Results indicated that despite many challenges in the first year of implementation, students in all 19 classrooms of this program demonstrated significant content and inquiry gains. In addition, case study data comprised of twice‐weekly classroom observations and interviews with the six teachers suggest support structures that were both conducive and challenging to inquiry pedagogy. Our work has extended previous studies on urban science pedagogy and practices as it has begun to articulate what role the technological component plays either in contributing to the challenges we experienced or in helping urban science classrooms to realize inquiry science and other positive learning values. Although these data outline results after only the first year of systemic reform, we suggest that they begin to build evidence for the role of technology‐rich inquiry programs in combating the pedagogy of poverty in urban science classrooms. © 2002 John Wiley & Sons, Inc.

While online learning resources are proliferating in all education delivery modes, from traditional classes to distance learning, institutions may have not recognized their potential for addressing diverse student populations, providing them online with learning experiences according to their individual needs. If teachers embrace online learning and customize their approaches to make online resources accessible to students, the interactive and collaborative nature of online learning may help reduce the lack of interaction in large classes and isolation in distance education. Research reports the need to examine the accessibility of online learning through the lenses of the digital divide dependence on factors related to physical access, skills and motivational factors. The circumstances of the pandemic have revealed inequality in access to education caused by access to technology and online delivery in which teaching approaches may not necessarily address the student voice with appreciation of their culture. Discussion address Kuo and Belland (Educ Technol Res Dev 64:661–680, 2016) article which reports experiences of minority students (e. g., African-American) in continuing education indicating that there has been little study of minority students' use of online learning resources. Authentic learning is highlighted by critical pedagogy as a means of engaging students in real-life problems and giving meaning to their real-life contexts as sources of learning and among which digital spaces play a prominent role in students’ meaning-making.

The issue of science subject knowledge, and how to address the demands of this for both practising and trainee primary teachers, has constituted a core research enterprise in recent decades. The Professional Standards for Qualified Teacher Status entail considerable conceptual demands for many primary trainees. Generating meaningful causal explanations of scientific phenomena lies at the heart of both the scientific endeavour itself, and of effective classroom teaching. To focus on knowledge acquisition per se in teacher education, however, obscures the critical issue of subject‐related pedagogical knowledge that ultimately influences classroom practice. This article explores the development of both subject knowledge and subject‐related pedagogical knowledge in science education. It is informed by science education literature, as well as by a substantial body of empirical research into trainees' learning of aspects of physical science accumulated over a five‐year period. Learners' perspectives of the synthesis of subject and pedagogy raise important questions concerning the nature of teacher education.  相似文献

This study aimed to determine how 33 urban 5th grade students' science conceptions changed during a place‐based inquiry unit on watersheds. Research on watershed and place‐based education was used as a framework to guide the teaching of the unit as well as the research study. A teacher‐researcher designed the curriculum, taught the unit and conducted the research using qualitative data sources such as concept maps, science notebooks and interviews. Most students came to understand that their watershed was part of an urban environment where water drains from the surrounding land into a body of water. Thus, they began to understand how urban land use affects water quality. This study provides evidence for the use of place‐based learning in developing students' knowledge of the National Science Education Standards (NRC, 1996) and watersheds. Implications of this study include the use of place‐based learning in urban settings and the experiences needed for students to conceptualize watersheds. © 2009 Wiley Periodicals, Inc.

3D printing technology is a powerful educational tool that can promote integrative STEM education by connecting engineering, technology, and applications of science concepts. Yet, research on the integration of 3D printing technology in formal educational contexts is extremely limited. This study engaged preservice elementary teachers (N?=?42) in a 3D Printing Science Project that modeled a science experiment in the elementary classroom on why things float or sink using 3D printed boats. The goal was to explore how collaborative 3D printing inquiry-based learning experiences affected preservice teachers’ science teaching self-efficacy beliefs, anxiety toward teaching science, interest in science, perceived competence in K-3 technology and engineering science standards, and science content knowledge. The 3D printing project intervention significantly decreased participants’ science teaching anxiety and improved their science teaching efficacy, science interest, and perceived competence in K-3 technological and engineering design science standards. Moreover, an analysis of students’ project reflections and boat designs provided an insight into their collaborative 3D modeling design experiences. The study makes a contribution to the scarce body of knowledge on how teacher preparation programs can utilize 3D printing technology as a means of preparing prospective teachers to implement the recently adopted engineering and technology standards in K-12 science education.  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

The purpose of this research was to understand how preservice elementary teacher experiences within the context of reflective science teacher education influence the development of professional knowledge. We conducted a case analysis to investigate one preservice teacher's beliefs about science teaching and learning, identify the tensions with which she grappled in learning to teach elementary science, understand the frames from which she identified problems of practice, and discern how her experiences played a role in framing and reframing problems of practice. The teacher, Barbara, encountered tensions in thinking about science teaching and learning as a result of inconsistencies between her vision of science teaching and her practice. Confronting these tensions between ideals and realities prompted Barbara to rethink the connections between her classroom actions and students' learning and create new perspectives for viewing her practice. Through reframing, she was able to consider and begin implementing alternative practices more resonant with her beliefs. Barbara's case illustrates the value of understanding prospective teachers' beliefs, their experiences, and the relationship between beliefs and classroom actions. Furthermore, the findings underscore the significance of offering reflective experience as professionals early in the careers of prospective teachers. © 1999 John Wiley & Sons, Inc.

In order to understand how prospective teachers develop knowledge for teaching, researchers must identify the types of knowledge that are integral to effective science teaching. This case study investigated how 4 prospective secondary biology teachers’ science teaching orientations, knowledge of science learners, and knowledge of instructional sequence, developed during a post-baccalaureate teacher education program. Data sources included a lesson planning task and two interview-observation cycles during the participants’ year-long internship. Over the course of a year, the participants’ science teaching orientations were based primarily on their K-16 learning experiences, and were robust and highly resistant to change. The prospective teachers became more aware of student learning difficulties, and therefore, developed more elaborated knowledge of the requirements of learning. They consistently sequenced instruction in ways that gave priority to transmitting information to students. Prospective teachers’ development of knowledge of student understanding of science and instructional sequence were congruent with their science teaching orientations. Implications are given for teacher education and future research.  相似文献

The teaching of science in K-12 schools has long been criticized as a process that propagates oppression for students who do not conform to entrenched norms of gender, sex, and sexuality. Academic standards, curriculum, and textbooks are rife with rhetoric that reinforces any deviation from cisheterosexuality as aberrant, unusual, or abnormal. However, these often-over-simplified conceptions discount the historic social and scientific intricacies of gender and sexual diversity as well as students' own lived experiences. While there have been advancements in LGBTQ+ and gender-inclusive science education reform, these movements have been stymied by a lack of cohesive guidelines for pedagogy and practice, particularly for trans, nonbinary, and gender-creative youth. Situated within trans-created conceptual frameworks for critical education, this study explored the pedagogical practices of 10 transgender science teachers with the purpose of learning from their experiences creating gender inclusive curriculum. From the data (in-depth interviews, instructional materials samples, and reflective teaching statements) emerged the TRANS (Trans and Research-informed Approaches for Nonbinary and gender-inclusive Science education) Framework for gender inclusive science education pedagogy. This framework is anchored in three domains for teaching science through a trans-informed lens:interrogating and accessing power, resisting essentialism, and embracing experiential knowledge and personal epistemologies. The findings of this study contribute to our growing understanding of gender-inclusive science learning environments. Importantly, this study amplified the experiential knowledge of teachers whose voices are critically absent from research surrounding gender and LGBTQ+-inclusive science education practice. Moreover, the framework derived from teachers' experiences can be used to guide educators in making their science classrooms safer and more gender inclusive.  相似文献

This study reports findings from a 10‐day professional development institute on curricular trends involving 19 secondary mathematics and science teachers and administrators from Japan, Malaysia, Indonesia, Thailand, Korea, Philippines, the United States, and People's Republic of China. Participants explored the roles of culture, place, and personal experience in science education through writings and group discussions. Initially, Asian participants tended to view indigenous knowledge and practices more negatively than U.S. peers. After a presentation on indigenous Hawaiian practices related to place and sustainability, they evaluated indigenous practices more positively and critiqued the absence of locally relevant science and indigenous knowledge in their national curricula. They identified local issues of traffic, air, and water quality they would like to address, and developed lessons addressing prior knowledge, place, and to a lesser extent, culture. These findings suggested critical professional development employing decolonizing methodologies articulated by indigenous researchers Abbott and Smith has the potential to raise teachers' awareness of the connections among personal and place‐based experiences, cultural practices and values, and teaching and learning. An implication was the development of a framework for professional development able to shift science instruction toward meaningful, culture, place, and problem‐based learning relevant to environmental literacy and sustainability. © 2007 Wiley Periodicals, Inc.

An oft-cited maxim in higher education is that “faculty teach the way they were taught” because they receive little formal training in teaching before entering the classroom. However, little is known about the origins of faculty knowledge about teaching or the role their prior experiences play in the development of their teaching practices. In this exploratory study, we interviewed and observed 53 science, technology, engineering, and mathematics faculty at three research institutions. Using qualitative analysis methods (i.e., thematic and causal network analysis), we find that faculty do not only model their teaching after previous instructors, but also draw upon a varied repertoire of knowledge and prior experiences. These include knowledge derived from their experiences as instructors (46 respondents), their experiences as students (22 respondents), their experiences as researchers (9 respondents), and from their non-academic roles (10 respondents). In-depth analyses of two faculty members elaborate on the relationship between these varied types of prior experiences and how they interact with other factors including beliefs about teaching, instructional goals, and features of the organizational context to ultimately shape their classroom practice. The results suggest that instead of assuming that faculty lack any knowledge about teaching and learning, professional developers and policymakers should instead acknowledge and build upon their preexisting “craft” knowledge as professional teachers. Future research should focus on relationships between specific types of knowledge and teaching practice and how these varied experiences influence identity formation.  相似文献

The purpose of this case study was to explore the ways in which 3 different informal science experiences in the context of an elementary methods course influenced a group of prospective elementary teachers' ideas about science teaching and learning as well as their understandings about the role of informal science environments to teaching and learning. In order to address this question, data were collected in a period of an academic semester through the following sources: journal entries for each of the 3 experiences, a personal teaching philosophy statement and a 2-hour long semi-structured interview with each of the 12 participants. Open coding techniques were used to analyze the data in order to construct categories and subcategories and eventually to identify emerging themes. The outcomes of the analysis showed that the inclusion of informal science experiences in the context of teacher preparation has the potential to support beginning elementary teachers' development of contemporary ideas about science teaching and learning related to inquiry-based science, the nature of scientific work and the work of scientists, connecting science with everyday life, and making science fun and personally meaningful. These findings are discussed alongside implications for policy, teacher preparation, and research under these themes: (a) addressing reform recommendations; (b) developing positive orientations toward science and science teaching; and (c) constructing understandings about scientists' work.  相似文献

Science education in the United Kingdom faces a dual challenge in the near future: that of addressing increasing disaffection from the subject by pupils as they enter adolescence coupled with the downturn in learning as they leave primary school behind. Both bridging work and teacher creativity have been identified as key ingredients in ensuring pupil engagement in learning, yet innovation requires both time and a broader vision than may be offered by a normative and centralized pedagogy. This paper proposes a four‐stage model for curriculum development to encourage creativity, based on the experiences of teachers as they designed bridging work for pupils in science. A grounded theory approach is utilized to generate four concept categories emerging from participants' comments during the study. These are described as uncertainty, visioning, realization and readiness, and this research demonstrates that ‘bottom–up’ is a very effective method of professional development promoting combinatorial thinking and creative science teaching.  相似文献
