Studies of the philosophy of chemistry over the past 15 years suggest that chemistry is a hybrid science which mixes scientific pursuits with technological applications. Dominant universal characterizations of the nature of science thus fail to capture the essence of the discipline. The central goal of this position paper is to encourage reflection about the extent to which dominant views about quality science education based on universal views of scientific practices may constrain school chemistry. In particular, we discuss how these predominant ideas restrict the development of chemistry curricula and instructional approaches that may better support the learning of the ideas and practices that studies of the philosophy of chemistry suggest are at the core of the discipline. Our analysis suggests that philosophical studies about the nature of chemistry invite us to transgress traditional educational boundaries between science and technology, inquiry and design, content and process, and to reconceptualize school chemistry as a paradigmatic techno scientific subject. To support these changes, chemical education researchers should expand the scope of their investigations to better understand how students and teachers reason about and engage in more authentic ways of chemical thinking and doing.  相似文献

This essay considers the question of why we should teach science to K-2. After initial consideration of two traditional reasons for studying science, six assertions supporting the idea that even small children should be exposed to science are given. These are, in order: (1) Children naturally enjoy observing and thinking about nature. (2) Exposing students to science develops positive attitudes towards science. (3) Early exposure to scientific phenomena leads to better understanding of the scientific concepts studied later in a formal way. (4) The use of scientifically informed language at an early age influences the eventual development of scientific concepts. (5) Children can understand scientific concepts and reason scientifically. (6) Science is an efficient means for developing scientific thinking. Concrete illustrations of some of the ideas discussed in this essay, particularly, how language and prior knowledge may influence the development of scientific concepts, are then provided. The essay concludes by emphasizing that there is a window of opportunity that educators should exploit by presenting science as part of the curriculum in both kindergarten and the first years of primary school.  相似文献

In the literature on the situated and distributed nature of cognition, the coordination of spatial organization and the structure of human practices and relations is accepted as a fact. To date, science educators have yet to build on such research. Drawing on an ethnographic study of high school students during an internship in a scientific research laboratory, which we understand as a “perspicuous setting” and a “smart setting,” in which otherwise invisible dimensions of human practices become evident, we analyze the relationship between spatial configurations of the setting and the nature and temporal organization of knowing and learning in science. Our analyses show that spatial aspects of the laboratory projectively organize how participants act and can serve as resources to help the novices to participate in difficult and unfamiliar tasks. First, existing spatial relations projectively organize the language involving interns and lab members. In particular, spatial relations projectively organize where and when pedagogical language should happen; and there are specific discursive mechanisms that produce cohesion in language across different places in the laboratory. Second, the spatial arrangements projectively organize the temporal dimensions of action. These findings allow science educators to think explicitly about organizing “smart contexts” that help learners participate in and learn complex scientific laboratory practices.  相似文献

Multicultural education, pragmatism, and the goals of science teaching   总被引:1,自引:1,他引:0  
In this paper, we offer an intermediate position in the multiculturalism/universalism debate, drawing upon Cobern and Loving’s epistemological pluralism, pragmatist philosophies, Southerland’s defense of instructional multicultural science education, and the conceptual profile model. An important element in this position is the proposal that understanding is the proper goal of science education. Our commitment to this proposal is explained in terms of a defense of an ethics of coexistence for dealing with cultural differences, according to which social argumentative processes—including those in science education—should be marked by dialogue and confrontation of arguments in the search of possible solutions, and an effort to (co-)live with differences if a negotiated solution is not reached. To understand the discourses at stake is, in our view, a key requirement for the coexistence of arguments and discourses, and the science classroom is the privileged space for promoting an understanding of the scientific discourse in particular. We argue for “inclusion” of students’ culturally grounded ideas in science education, but in a sense that avoids curricular multicultural science education, and, thus, any attempt to broaden the definition of “science” so that ideas from other ways of knowing might be simply treated as science contents. Science teachers should always take in due account the diversity of students’ worldviews, giving them room in argumentative processes in science classrooms, but should never lose from sight the necessity of stimulating students to understand scientific ideas. This view is grounded on a distinction between the goals of science education and the nature of science instruction, and demands a discussion about how learning is to take place in culturally sensitive science education, and about communicative approaches that might be more productive in science classrooms organized as we propose here. We employ the conceptual profile model to address both issues. We expect this paper can contribute to the elaboration of an instructional multicultural science education approach that eliminates the forced choice between the goals of promoting students’ understanding of scientific ideas and of empowering students through education.

Science education models for secondary and college students as well as K‐12 teachers have been dominated by classroom‐based approaches. Recently, research apprenticeships wherein learners worked with practicing scientists on authentic scientific research have become increasingly popular. The purpose of this critical review of the literature was to review and synthesize empirical studies that have explored learning outcomes associated with research apprenticeships for science learners. We reviewed 53 studies of scientific research apprenticeship experiences for secondary students, undergraduates and teachers, both pre‐service and in‐service. The review explored various learning outcomes associated with participation in research apprenticeships. These outcomes included effects of apprenticeship experiences on participant career aspirations, ideas about the nature of science (NOS), understandings of scientific content, confidence for doing science and intellectual development. The extant literature supported many of the presumed positive associations between apprenticeship experiences and desired learning outcomes, but findings related to some themes (e.g., NOS understandings) supported conflicting conclusions. Implications included importance of the length of the apprenticeship, need to explicitly place attention on desired outcomes, and engagement of participants. © 2009 Wiley Periodicals, Inc.

The article focuses on defining the role of demonstration in general and experiments in particular in science education at the high school level, on the basis of psychological data and recent conceptions about the nature of science. It is argued that experiments play a restricted role in transmitting knowledge, but may be used as deductions demonstrating concepts; they are useless or harmful in teaching problem-solving but important as aids in testing alternative solutions and in training specific scientific skills; and finally, they are not the best means for evoking and maintaining curiosity in adolescents. Special consideration is paid to the role of concepts and concretizations in science, adolescent thinking and science instruction.  相似文献

Research in the teaching and learning of evolutionary biology has revealed persistent difficulties in student understanding of fundamental Darwinian concepts. These difficulties may be traced, in part, to science instruction that is based on philosophical conceptions of science that are no longer viewed as adequately characterizing the diverse nature of scientific practice, especially in evolutionary biology. This mismatch between evolution as practiced and the nature of science as perceived by researchers and educators has a long history extending back to the publication of Darwin's theory of natural selection. An examination of how this theory was received by the scientific community of the time may provide insight into some of the difficulties that students have today in learning these important biological concepts. The primary difficulties center around issues of metaphysics and scientific method, aspects of the nature of science too often ignored in science education. Our intent is not to offer a specific course of action to remedy the problems educators currently face, but rather to suggest an alternative path one might take to eventually reach a solution. That path, we argue, should include the use of broader models of science that incorporate these elements of scientific practice to structure teaching and education research in evolution. © 1998 John Wiley & Sons, Inc.

The notion of “science for all” suggests that all students—irrespective of achievement and ability—should engage in opportunities to understand the practice and discourse of science. Improving scientific literacy is an intrinsic goal of science education, yet current instructional practices may not effectively support all students, in particular, students with special needs. Argument‐based inquiry approaches, such as the Science Writing Heuristic (SWH), require all students to construct their scientific understandings by engaging in investigations and negotiating their ideas in multiple contexts, such as discussions and writing. Various SWH studies demonstrated that students engaged in appropriating the language, culture, practice, and dispositions of science generally improved their critical thinking and standardized test scores. The implementation of such an approach has several implications for science and special education research and practice, including how learning environments should be established to encourage the inclusion of all students’ ideas, as well as how scaffolded supports can and should be used to support science learning.  相似文献

In this article, we authors and feminist science and teacher educators share assignments we developed and used in our undergraduate and graduate teacher education classes. We designed these varied assignments to help students feel comfortable with science, to begin to understand and critique the many ways science has been narrowly and powerfully shaped and has marginalized significant groups of individuals, and to begin to deconstruct scientific knowledge and construct alternative views of science and science education that are gender and culture sensitive. We also challenged them to use what they were learning to develop pedagogical strategies that would be inviting to their own students. The focus of the article is our students' reactions to these assignments and how these reactions—both inviting and resisting—informed us about their notions of science, of teaching, of themselves as learners, and of the social context in which they would teach. © 1998 John Wiley & Sons, Inc.

This article describes views about the nature of science held by a small sample of science students in their final year at the university. In a longitudinal interview study, 11 students were asked questions about the nature of science during the time they were involved in project work. Statements about the nature of science were characterized and coded using a framework drawing on aspects of the epistemology and sociology of science. The framework in this study has three distinct areas: the relationship between data and knowledge claims, the nature of lines of scientific enquiry, and science as a social activity. The students in our sample tended to see knowledge claims as resting solely on empirical grounds, although some students mentioned social factors as also being important. Many of the students showed significant development in their understanding of how lines of scientific enquiry are influenced by theoretical developments within a discipline, over the 5–8 month period of their project work. Issues relating to scientists working as a community were underrepresented in the students' discussions about science. Individual students drew upon a range of views about the nature of science, depending on the scientific context being discussed. © 1999 John Wiley & Sons, Inc.

Arguments for teaching about the nature of science have been made for several decades. The most recent science education policy documents continue to assert the need for students to understand the nature of science. However, little research actually explores how students develop these understandings in the context of a specific course. We examine the growth in students' understanding about the nature of astronomy in a one‐semester college course. In addition to student work collected for 340 students in the course, we also interviewed focus students three times during the course. In this article we briefly describe class data and discuss in detail how five students developed their ideas throughout the course. In particular, we show the ways in which students respond to instruction with respect to the extent to which they (a) demand and examine evidence used for justifying claims, (b) integrate scientific and religious views, and (c) distinguish between scientific and nonscientific theories. © 2000 John Wiley & Sons, Inc.

Teaching about the nature of science (NOS) is seen as a priority for science education in many national contexts. The present paper focuses on one central issue in learning about NOS: understanding the nature and status of scientific theories. A key challenge in teaching about NOS is to persuade students that scientific knowledge is generally robust and reliable, yet also in principle always open to challenge and modification. Theories play a central role, as they are a form of conjectural knowledge that over time may be abandoned, replaced, modified, yet sometimes become well established as current best scientific understanding. The present paper reports on findings from interviews with 13–14 year olds in England where target knowledge presents theories as ‘consistent, comprehensive, coherent and extensively evidenced explanations of aspects of the natural world’. Student thinking reflected a two-tier typology of scientific knowledge in which largely unsupported imaginative ideas (‘theories’) became transformed into fairly definitive knowledge (such as laws) through relatively straightforward testing. These results are considered in relation to research into intellectual development which indicates that effective teaching in this area requires careful scaffolding of student learning, but has potential to contribute to supporting intellectual development across the curriculum.  相似文献

Various science education researchers believe that science tuition should include some discussion about how science has developed over time. Therefore, deliberations about the nature of science should be integrated in the science curriculum. Many researchers argue that teaching the history of science is a good way to place the nature of science in science classes. This paper contributes to this debate and argues the importance of having young students study the birth of modern science. Such study could allow students to understand that some of the issues about the nature of science arose in the seventeenth century with the birth of modern science. To achieve this purpose, it is important to discuss the different factors that immersed the birth of modern science. To accomplish this goal, the novel The Name of the Rose by Umberto Eco may be used. Beyond introducing issues surrounding the nature of science, this strategy could help overcome the separation between the arts and humanities in education.  相似文献

As biotechnology‐related scientific advances, such as stem cell research (SCR), are increasingly permeating the popular media, it has become ever more important to understand students’ ideas about this issue. Very few studies have investigated learners’ ideas about biotechnology. Our study was designed to understand the types of alternative conceptions students hold concerning SCR. The qualitative research design allowed us to examine college students’ understandings about stem cells and SCR. More specifically, we addressed the following questions: How can alternative conceptions about stem cell topics be categorized? What types of alternative conceptions are most common? Participants included 132 students enrolled in a biotechnology course that focused on the scientific background of biotechnology applications relevant to citizens. In this study, we used an inductive approach to develop a taxonomy of alternative ideas about SCR by analyzing student responses to multiple open‐ended data sources. We identified five categories of conceptions: alternative conceptions about what, alternative conceptions about how, alternative conceptions about medical potential, terminology confusion, and political and legal alternative conceptions. In order to improve instruction, it is important to understand students’ ideas when entering the classroom. Our findings highlight a need to teach how science can be applied to societal issues and improve science literacy and citizenship.  相似文献

Science education communities around the world have increasingly emphasized engaging students in the disciplinary practices of science as they engage in high levels of reasoning about scientific ideas. Consistently, this is a critical moment in time in the USA as it goes through a new wave of science education reform within the context of Next Generation Science Standards (NGSS). We argue that the placement of high demands on students’ thinking (i.e., a high level of thinking) in combination with positioning students to use disciplinary practices as they try to make sense of scientific ideas (i.e., a deep kind of thinking) constitute critical aspects of the reform. The main purpose of this paper is to identify and describe the kinds and levels of thinking in which students engage when they are invited to think and reason as demanded by NGSS-aligned curricular tasks. Our analysis of video records of classrooms in which an NGSS-aligned, cognitively demanding task was used, revealed many ways in which the aspirational level and kind of student thinking will not be met in many science classrooms. We propose a way of characterizing and labeling the differences among these kinds and levels of thinking during the implementation of a reform-based biology curriculum. These categories, which focus on two important features emphasized in the NGSS, can help us to better understand, diagnose, and communicate issues during the implementation of high-level tasks in science classrooms.

The purpose of this study was to explore the effectiveness of the creative inquiry-based science teaching on students’ creative science thinking and science inquiry performance. A quasi-experimental design consisting one experimental group (N?=?20) and one comparison group (N?= 24) with pretest and post-test was conducted. The framework of the intervention focused on potential strategies such as promoting divergent and convergent thinking and providing an open, inquiry-based learning environment that are recommended by the literature. Results revealed that the experimental group students outperformed their counterparts in the comparison group on the performances of science inquiry and convergent thinking. Additional qualitative data analyses from classroom observations and case teacher interviews identified supportive teaching strategies (e.g. facilitating associative thinking, sharing impressive ideas, encouraging evidence-based conclusions, and reviewing and commenting on group presentations) for developing students’ creative science thinking.  相似文献
