This study investigated ways to foster positive science attitudes among newcomer first-year middle school English learners (n?=?79) under two conditions: (1) Extended Science?+?Extended Literacy (planetarium-based visualisations?+?vocabulary?+?comic and trade books) and (2) Extended Science?+?Literacy (planetarium-based visualisations?+?vocabulary). The results indicated a statistically and practically meaningful increase in science attitudes (Cohen’s d?=?0.43) after an 8-week science unit delivered under the Extended Science?+?Extended Literacy condition, which was maintained, but not increased, for the second 8-week unit under the Extended Science?+?Literacy condition. These results suggest that the combination of planetarium-based visualisations and comic and trade books can be effective for supporting newcomer ELs’ science attitudes. However, once achieved, this effect may be maintained with less intensive literacy (vocabulary only) support. Student judgments of the quality of the planetarium-based visualisation experiences in terms of clarity, easiness, excitement, and usefulness began high and went even higher with more experiences, Cohen’s d?>?0.50 for three out of four quality indicators. Interviews corroborated these results with teacher and students indicating that they highly valued the visually-rich nature of the program, the variety of learning opportunities within the program, and program continuity/close alignment between science and literacy supports—all components contributing to high levels of engagement and positive attitudes toward science. Ways to adopt program components across settings are discussed.  相似文献

Teacher education is in the grip of change. Due to the new Australian Curriculum, no longer is it possible to plan and implement lessons without considering the inclusion of Information and Communication Technologies. Simply knowing about the latest technology gadgets is not enough. Information literacy is essential in today’s information-rich learning and working environment. Students and teachers must be able to engage with diverse learning technologies efficiently and effectively in the search for the “right information” at the “right time” for the “right purpose”. Key information literacy and inquiry skills have been recognised as vital learning goals by the Australian Curriculum Assessment and Reporting Authority and the International Society for Technology in Education and are thus critical in science teacher education. This paper examines the overlap of technology, pedagogy and science content in the Technological Pedagogical and Content Knowledge (TPACK) framework and its affordances for science educators, at the intersection between technology knowledge, science pedagogy (information literacy and inquiry) and science content knowledge. Following an introduction of the TPACK framework for science education, the paper reports the research findings, which illustrate that 90% of pre-service teachers thought the experimental unit improved their understanding of the inquiry process, 88% reported more confidence in their understanding of science concepts and 94% of students reported an increase in their knowledge and confidence of Web 2.0 tools in supporting scientific inquiry in science. The implications of this study are that the online inquiry improved students’ knowledge and confidence in the skills and processes associated with inquiry and in science concepts.  相似文献

In the course of a decade of research on learning in technology‐centered classrooms, my research group has gained considerable understanding of why and how students learn science by designing technology. In this article I briefly review two dimensions in which science and technology share fundamental similarities: (a) the production and transformation of representations and (b∥ the action‐oriented language describing the two domains. Because it is fundamentally problematic to derive what ought to happen in science classrooms from other dimensions, I provide three episodes to illustrate what and how students know and learn science during technological design activities. Episodes and analyses embody the two dimensions previously outlined. Because these episodes are representative of the database established during an extensive research program, I suggest there is sufficient ground for using and investigating science‐through‐technology curricula. © 2001 John Wiley & Sons, Inc.

This study examines Turkish pre-service science teachers' understanding of science concepts and their confidence in its teaching. A total of 299 senior science education major students participated in the study. Data collection instruments included the Science Concepts Test, and the Science Teaching Efficacy Belief Instrument. Although findings of the study indicated that majority of the participants held misconceptions concerning fundamental science concepts, they generally felt confident about teaching it. The relationship that might exist among pre-service science teachers' confidence in their effectiveness in teaching and the number of the science courses completed in university is examined.  相似文献

ABSTRACT

What are the current challenges and opportunities for bringing actor-network theory (ANT) into issues-based science education? This article discusses experiences gained from introducing an educational version of ANT deploying digital technology into an upper secondary school science class. This teaching innovation, called controversy mapping, has been pioneered in different contexts of higher education before being adapted to school education. Experimenting with controversy mapping in a Swedish science class raised both conceptual and practical issues. These centre on: (1) how ANT-inspired controversy mapping redesigns the citizenship training enacted by institutionalized approaches to issues-based education as socioscientific issues (SSI); (2) how controversy mapping reconfigures the interdisciplinarity of issues-based science education; and (3) how controversy mapping displaces scientific literacy and knowledge of the nature of science as guiding concerns for teaching in favour of new preoccupations with digital literacy and digital tools and methods as contemporary infrastructures of free and open inquiry.  相似文献

In this paper, I present a critical review of the recent book, Science Education as a Pathway to Teaching Language Literacy, edited by Alberto J. Rodriguez. This volume is a timely collection of essays in which the authors bring to attention both the successes and challenges of integrating science instruction with literacy instruction (and vice versa). Although several themes in the book merit further attention, a central unifying issue throughout all of the chapters is the task of designing instruction which (1) gives students access to the dominant Discourses in science and literacy, (2) builds on students’ lived experiences, and (3) connects new material to socially and culturally relevant contexts in both science and literacy instruction—all within the high stakes testing realities of teachers and students in public schools. In this review, I illustrate how the authors of these essays effectively address this formidable challenge through research that ‘ascends to the concrete’. I also discuss where we could build on the work of the authors to integrate literacy and science instruction with the purpose of ‘humanizing and democratizing’ science education in K-12 classrooms.  相似文献

Science literacy for all is the central goal of science education reforms, and there is a growing importance of the language arts in science. Furthermore, there are strong calls for teacher professionalism and self-directed professional learning that involve evidence-based best practices. This raises questions about whether science teaching journals?? recommendations are anchored to high-quality evidence. We found that (a) most National Science Teacher Association journals?? science literacy recommendations have weak or no evidence base and (b) those with evidence reference teaching journals, teacher resource books, and literacy education more often than science education research. We concluded that all participants in the knowledge production cycle and transfer process??authors, editors, and reviewers??need to encourage evidence-based practices anchored to ongoing reforms and to literacy and science education research.  相似文献

Measuring the impact of a science center on its community   总被引：1，自引：1，他引：0  
A range of sources support science learning, including the formal education system, libraries, museums, nature and Science Centers, aquariums and zoos, botanical gardens and arboretums, television programs, film and video, newspapers, radio, books and magazines, the Internet, community and health organizations, environmental organizations, and conversations with friends and family. This study examined the impact of one single part of this infrastructure, a Science Center. This study asked two questions. First, who in Los Angeles (L.A.) has visited the California Science Center and what factors best describe those who have and those who have not visited? Second, does visiting the California Science Center impact public science understanding, attitudes, and behaviors and if so, in what ways? Two random telephone surveys of L.A. county adults 18 years of age and over (n = 832; n = 1,008) were conducted; one in 2000, shortly after the opening of the totally redesigned and rebuilt Science Center and one in 2009, roughly a decade after opening. Samples were drawn from five racially, ethnically, and socio‐economically diverse communities generally representative of greater L.A. Results suggest that the Science Center is having an important impact on the science literacy of greater L.A. More than half of residents have visited the Science Center since it opened in 1998 and self‐report data indicate that those who have visited believe that the Science Center strongly influenced their science and technology understanding, attitudes, and behaviors. Importantly, Science Center visitors are broadly representative of the general population of greater L.A. including individuals from all races and ethnicities, ages, education, and income levels with some of the strongest beliefs of impact expressed by minority and low‐income individuals. The use of a conceptual “marker” substantiates these conclusions and suggests that the impact of the Science Center might even be greater than indicated by the mostly self‐report data reported here. © 2010 Wiley Periodicals, Inc.

This ethnographic study of a third grade classroom examined elementary school science learning as a sociocultural accomplishment. The research focused on how a teacher helped his students acquire psychological tools for learning to think and engage in scientific practices as locally defined. Analyses of classroom discourse examined both how the teacher used mediational strategies to frame disciplinary knowledge in science as well as how students internalized and appropriated ways of knowing in science. The study documented and analyzed how students came to appropriate scientific knowledge as their own in an ongoing manner tied to their identities as student scientists. Implications for sociocultural theory in science education research are discussed.

An important goal of science education is promoting scientific literacy—the competence to interact with science as laypeople to solve problems and make decisions in their personal and community lives. This is made more challenging in an age of increasing science denialism. In this article, we discuss how to design learning environments for science education that can help students attain scientific literacy. We argue that science curricula should encompass lessons with two distinguishable foci. One focus engages students in understanding the reliability of science. The second focus engages students as laypeople interacting with science in the public sphere. We discuss these two curricular foci, presenting examples from our own work on designing and implementing instruction with the first focus.  相似文献

The purpose of this article is to describe a community‐based science project that was coproduced with urban teenagers and to elaborate on my understanding of what it means to create a practicing culture of science learning. This understanding will be positioned in relation to various educationally relevant discourses and research on urban science education, concluding with an exploration of these questions: In what ways did an urban planning and community gardening project help to create a learning environment in which science was relevant? To whom was science relevant and toward what ends? It is argued that in a practicing culture of science learning, science was relevant because (a) it was created from participants' concerns, interests, and experiences inside and outside science, (b) it was an ongoing process of researching and then enacting ideas, and (c) it was situated within the broader community. © 2001 John Wiley & Sons, Inc.

The Ontario Science Centre is a popular alternative learning environment for science and technology. Using semi-structured interviews, the research underpinning this paper investigates the experiences and effects of working as a Host or exhibit interpreter at the Science Centre. It examines how the Hosts benefit from the program in terms of their knowledge about and attitudes toward science and technology. What is distinctive about learning in this context, and its implications for science and technology education in schools, are discussed. The dominant aspects of learning for the respondents tended to be inspirational and attitudinal, as well as cognitive. The comments of the respondents indicate that in order to encourage learning in science and technology, science education needs to focus on more than a narrow concern with curriculum content.  相似文献

How students come to know phenomena in terms of abstract concepts and theories through hands-on activities remains one of the open problems in science education. In this study, we develop a theory of learning science through design activities by employing a dialectical view of human activity that explicitly combines the mental and material in the same, irreducible unit of analysis. Dialectical contradictions embodied by this unit, here conceptualized as resistance experienced from a first-person perspective, constitute the inner forces that drive designing. Drawing on a large database of artifact designing constituted during a four-month unit on simple machines, we examine how resistance, in its dialectical relation to contradiction contributes to the unfolding design process and to the learning of scientific concepts and manual process skills during design. First, an inner contradiction emerges in the designers' lifeworlds as an unintended outcome or a breakdown and thereby changes the perceived world of a designer collective. Second, the dialectic of contradiction and resistance realized in this manner constitutes a moment unfolding culture of science in its concrete form embodied in individual designers and therefore contributes to the production and reproduction of culture. We conclude with a reflection on the implications our study makes to a non-dualist view of knowing and learning.

The transfer of matter and energy from one organism to another and between organisms and their physical setting is a fundamental concept in life science. Not surprisingly, this concept is common to the Benchmarks for Science Literacy (American Association for the Advancement of Science, 1993 ), the National Science Education Standards (National Research Council, 1996 ), and most state frameworks and likely to appear in any middle‐school science curriculum material. Nonetheless, while topics such as photosynthesis and cellular respiration have been taught for many years, research on student learning indicates that students have difficulties learning these ideas. In this study, nine middle‐school curriculum materials—both widely used and newly developed—were examined in detail for their support of student learning ideas concerning matter and energy transformations in ecosystems specified in the national standards documents. The analysis procedure used in this study was previously developed and field tested by Project 2061 of the AAAS on a variety of curriculum materials. According to our findings, currently available curriculum materials provide little support for the attainment of the key ideas chosen for this study. In general, these materials do not take into account students' prior knowledge, lack representations to clarify abstract ideas, and are deficient in phenomena that can be explained by the key ideas and hence can make them plausible. This article concludes with a discussion of the implications of this study to curriculum development, teaching, and science education research based on shortcomings in today's curricula. © 2004 Wiley Periodicals, Inc.

Student‐directed, open‐ended scientific investigations and invention projects may serve to deepen and broaden students’ scientific and technological literacy, and, in so doing, enable them to succeed in democracies greatly affected by processes and products of science and technology. Science fairs, events at which student‐led projects are evaluated and celebrated, could contribute to such positive personal and social outcomes. Qualitative data drawn from a national science fair over succeeding years indicate (after analyses of largely qualitative data, using constant comparative methods) that, apart from positive outcomes regarding science literacy, there may be some significant issues about the fair that warrant critical review. It is apparent from these studies that there are issues of access, image, and recruitment associated with the fair. Qualification for participation in the fair appears to favour students from advantaged, resource‐rich backgrounds. Although these students do benefit in a number of ways from the fair experience, it is apparent that science fairs also greatly benefit sponsors—who can, in a sense, use science fairs for promotional and recruitment purposes. These findings and claims raised, for us, some important questions possibly having implications for science education, and for society more generally.  相似文献

This paper examines the continuation of a study investigating senior secondary students' understanding of concepts in biology. In this study, year 11 student understandings of natural selection were examined by questionnaire using different question formats. The SOLO taxonomy of Biggs and Collis (1982) was used as the theoretical framework with which the quality of student learning was assessed. This paper puts forward the usefulness of the SOLO taxonomy in assessing student understanding in biology in general and in examining student understanding of the concept of natural selection in particular. The paper goes on to examine the implications of these results and raises issues which have applicability to criterion-based assessment in secondary science.

Quantitative literacy is an important proficiency that pertains to “word problems” from science, history, and other fields. Unfortunately, teaching how to solve such problems often is relegated to math courses alone. This article examines how quantitative literacy also involves concepts and skills from English composition and the substantive disciplines. The author outlines a systematic approach to writing the answers to word problems—a fundamental skill that applies to ongoing education, everyday life, and the workplace.  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

Benchmarks for Science Literacy (AAAS 1993) lists for four gradelevels the steps by which students might achieve science literacy before leaving high school. These steps and the conceptual connections among them are now being mapped to suggest where anyone idea or skill comes from, what it is connected to, and where it leads. A set of 49 such strand maps appears in Atlas of Science Literacy (AAAS 2001). This paperdescribes strand maps in general and examinesthree draft maps titled Evidence and Reasoning, Scientific Investigations, and Scientific Theories, which together represent one section of Benchmarks Chapter 1, on scientific inquiry. The maps do not prescribe any particular curriculum, but can aid in planning a variety of curricula, analyzing instructional materials, assessing student understanding, and can be used in professional development for teachers.  相似文献

ABSTRACT

The study provides an insight into how teachers may facilitate students’ group learning in science with digital technology, which was examined when Norwegian lower secondary school students engaged in learning concepts of mitosis and meiosis. Quantitative and qualitative analyses of the teacher’s assistance draw on Galperin’s conceptualisation of learning.

Findings reveal patterns in the teacher’s guidance: the teacher fulfilled the orienting, executive and controlling functions while assisting students in identifying the key features of mitosis and meiosis and solving the compare and contrast task. The teacher relied on and interplayed with the available mediational resources: compare and contrast task, digital animations, and collaborating peers. However, it was the compare and contrast task that demonstrated an approach to study scientific concepts which may have contributed to the development of learners’ understanding about to engage in learning in science. By adopting such an approach, learning activity has the potential to not only help students to achieve learning outcomes but it acquires a functional significance, becoming a tool in the learning process aimed at the development of students’ as learners. The digital animations, in turn, demonstrated scientific processes that were otherwise invisible for students and triggered group discussions. The study, therefore, raises questions about the need for practitioners’ awareness of the type of support the technology and other resources provide to assist both conceptual learning and enhancing students’ agency in learning to learn.  相似文献
