When evaluating equity, researchers often look at the “achievement gap.” Privileging knowledge and skills as primary outcomes of science education misses other, more subtle, but critical, outcomes indexing inequitable science education. In this comparative ethnography, we examined what it meant to “be scientific” in two fourth‐grade classes taught by teachers similarly committed to reform‐based science (RBS) practices in the service of equity. In both classrooms, students developed similar levels of scientific understanding and expressed positive attitudes about learning science. However, in one classroom, a group of African American and Latina girls expressed outright disaffiliation with promoted meanings of “smart science person” (“They are the science people. We aren't like them”), despite the fact that most of them knew the science equally well or, in one case, better than, their classmates. To make sense of these findings, we examine the normative practice of “sharing scientific ideas” in each classroom, a comparison that provided a robust account of the differently accessible meanings of scientific knowledge, scientific investigation, and scientific person in each setting. The findings illustrate that research with equity aims demands attention to culture (everyday classroom practices that promote particular meanings of “science”) and normative identities (culturally produced meanings of “science person” and the accessibility of those meanings). The study: (1) encourages researchers to question taken‐for‐granted assumptions and complexities of RBS and (2) demonstrates to practitioners that enacting what might look like RBS and producing students who know and can do science are but pieces of what it takes to achieve equitable science education. © 2011 Wiley Periodicals, Inc., Inc.

Science education reformers have argued that presenting science in the abstract is neither motivating nor inclusive of the majority of students. Science–technology–society (STS) curricula that give science an accessible social context have developed in response, but controversy surrounds the extent to which students should be introduced to socioscientific debate. Using material from a case study of Salters' Advanced Chemistry in the United Kingdom, this article demonstrates how socioscientific material is marginalized through the structures and language of syllabus texts and through classroom practices. This means students are unlikely to engage with socioscientific aspects in their course. Socioscientific content is gendered through association with social concerns and epistemological uncertainty, and because gender is asymmetric, socioscience is devalued with respect to the masculinity of abstract science. Teachers fear that extensive coverage of socioscience devalues the curriculum, alienates traditional science students and jeopardizes their own status as gatekeepers of scientific knowledge. Thus, although STS curricula such as Salters' offer potential for making science more accessible, the article concludes that greater awareness of, and challenges to, gender binaries could result in more effective STS curriculum reform. © 2000 John Wiley & Sons, Inc.

The inclusion of Nature of Science (NOS) in the science curriculum has been advocated around the world for several decades. One way of defining NOS is related to the family resemblance approach (FRA). The family resemblance idea was originally described by Wittgenstein. Subsequently, philosophers and educators have applied Wittgenstein’s idea to problems of their own disciplines. For example, Irzik and Nola adapted Wittgenstein’s generic definition of the family resemblance idea to NOS, while Erduran and Dagher reconceptualized Irzik and Nola’s FRA-to-NOS by synthesizing educational applications by drawing on perspectives from science education research. In this article, we use the terminology of “Reconceptualized FRA-to-NOS (RFN)” to refer to Erduran and Dagher’s FRA version which offers an educational account inclusive of knowledge about pedagogical, instructional, curricular and assessment issues in science education. Our motivation for making this distinction is rooted in the need to clarify the various accounts of the family resemblance idea.The key components of the RFN include the aims and values of science, methods and methodological rules, scientific practices, scientific knowledge as well as the social-institutional dimensions of science including the social ethos, certification, and power relations. We investigate the potential of RFN in facilitating curriculum analysis and in determining the gaps related to NOS in the curriculum. We analyze two Turkish science curricula published 7 years apart and illustrate how RFN can contribute not only to the analysis of science curriculum itself but also to trends in science curriculum development. Furthermore, we present an analysis of documents from USA and Ireland and contrast them to the Turkish curricula thereby illustrating some trends in the coverage of RFN categories. The results indicate that while both Turkish curricula contain statements that identify science as a cognitive-epistemic system, they underemphasize science as a social-institutional system. The comparison analysis shows results such as the “scientific ethos” category being mentioned by the Irish curriculum while “social organizations and interactions” category being mentioned by the Turkish curriculum. In all documents, there was no overall coherence to NOS as a holistic narrative that would be inclusive of the various RFN categories simultaneously. The article contributes to the framing of NOS from a family resemblance perspective and highlights how RFN categories can be used as analytical tools.  相似文献

Science education standards established by American Association for the Advancement of Science (AAAS) and the National Research Council (NRC) urge less emphasis on memorizing scientific facts and more emphasis on students investigating the everyday world and developing deep understanding from their inquiries. These approaches to instruction challenge teachers and students, particularly urban students who often have additional challenges related to poverty. We report data on student learning spanning 3 years from a science education reform collaboration with the Detroit Public Schools. Data were collected from nearly 8,000 students who participated in inquiry‐based and technology‐infused curriculum units that were collaboratively developed by district personnel and staff from the University of Michigan as part of a larger, district‐wide systemic reform effort in science education. The results show statistically significant increases on curriculum‐based test scores for each year of participation. Moreover, the strength of the effects grew over the years, as evidenced by increasing effect size estimates across the years. The findings indicate that students who historically are low achievers in science can succeed in standards‐based, inquiry science when curriculum is carefully developed and aligned with professional development and district policies. Additional longitudinal research on the development of student understanding over multiple inquiry projects, the progress of teacher enactment over time, and the effect of changes in the policy and administrative environment would further contribute to the intellectual and practical tools necessary to implement meaningful standards‐based systemic reform in science. © 2004 Wiley Periodicals, Inc.

Recognizing the persistent science achievement gap between inner‐city African American students and students from mainstream, White society, this article suggests that the imposition of external standards on inner‐city schools will do little to ameliorate this gap because such an approach fails to address the significance of the social and cultural lives of the students. Instead, it is suggested that the use of critical ethnographic research would enable educators to learn from the students how science education can change to meet their aims and interests. The article includes a report on how a science lunch group in an inner‐city high school forged a community based on respect and caring and how this community afforded African American male teens the opportunity to participate in science in new ways. © 2001 John Wiley & Sons, Inc.

Recent arguments in science education have proposed that school science should pay more attention to teaching the nature of science and its social practices. However, unlike the content of science, for which there is well‐established consensus, there would appear to be much less unanimity within the academic community about which “ideas‐about‐science” are essential elements that should be included in the contemporary school science curriculum. Hence, this study sought to determine empirically the extent of any consensus using a three stage Delphi questionnaire with 23 participants drawn from the communities of leading and acknowledged international experts of science educators; scientists; historians, philosophers, and sociologists of science; experts engaged in work to improve the public understanding of science; and expert science teachers. The outcome of the research was a set of nine themes encapsulating key ideas about the nature of science for which there was consensus and which were considered to be an essential component of school science curriculum. Together with extensive comments provided by the participants, these data give some measure of the existing level of agreement in the community engaged in science education and science communication about the salient features of a vulgarized account of the nature of science. Although some of the themes are already a feature of existing school science curricula, many others are not. The findings of this research, therefore, challenge (a) whether the picture of science represented in the school science curriculum is sufficiently comprehensive, and (b) whether there balance in the curriculum between teaching about the content of science and the nature of science is appropriate. © 2003 Wiley Periodicals, Inc.

Current high school Earth Science curricula and textbooks organize scientific content into isolated “units” of knowledge. Within this structure, content is taught, but in the absence of the context of fundamental understandings or the process of how the science was actually done to reach the conclusions. These are two key facets of scientific literacy. I have developed curriculum from a historical perspective that addresses two particular units of study in Earth Science (“geologic time” and “plate tectonics”). The curriculum traces the evolution of the theory of plate tectonics. It includes contextualized experiences for students such as telling stories, utilizing original historical texts, narratives, and essential questions, to name a few. All of the strategies are utilized with the goal of building understanding around a small set of common themes. Exploring the historical models in this way allows students to analyze the models, while looking for limitations and misconceptions. This methodology is used to encourage students to develop more scientifically accurate understandings about the way in which the world and the process of scientific discovery work. Observations of high student engagement during the utilization of this contextualized approach has demonstrated that a positive effect on student understanding is promising.  相似文献

This article is focused on changes taking place in the teaching of science as part of general education. Over the past century a host of changes in the nature and practice of science have served to make outmoded the science curricula now found in school textbooks. Past and present reform efforts have been limited to updating traditional subject matter, which is not adequate for life and living in today's world. A new framework is required for a general education in science, one that is student centered and up‐to‐date on the nature of science technology. As stated in the Science Bulletin ( 2000 ), “Science and technology have become the driving force for mankind's quest for a better society” (p. 1). The new science curriculum also should be focused on the utilization of science technology for public welfare and human benefit. © 2002 John Wiley & Sons, Inc. J Res Sci Teach 39: 3–9, 2002  相似文献

Why would individuals who are capable of learning opt not to? Learning is important for stability and success. It would seem rational that students in groups that are frequently underrepresented or marginalized would be motivated to learn. However, negotiation of multiple identities and self-beliefs can impact motivations to learn. For example, young African American males frequently adopt a “cool pose” in their approach to education. They maintain that they do not care and will not try to be a part of the existing educational system. To better understand these issues, we studied African American males in the Glitch Game Testers program. High school students in the Glitch program worked as paid game testers and took workshops in computer science. More than 65% of the participants went on to study computing after high school. We found that these students persisted with education and computing because they navigated around motivations to not learn by creating many different faces for their involvement with Glitch. In this article, we explore the use and design implications of face-saving tactics these young men used to “geek out” on computer programming, choose computer science for their career, and maintain their current identities with friends and families.  相似文献

For more than half a century concerns about the ability of American students to compete in a global workplace focused policymakers' attention on improving school performance generally, and student achievement in science, technology, engineering, and mathematics (STEM) specifically. In its most recent form—No Child Left Behind—there is evidence this focus led to a repurposing of instructional time to dedicate more attention to tested subjects. While this meant a narrowing of the curriculum to focus on English and mathematics at the elementary level, the effects on high school curricula have been less clear and generally absent from the research literature. In this study, we sought to explore the relationship between school improvement efforts and student achievement in science and thus explore the intersection of school reform and STEM policies. We used school‐level data on state standardized test scores in English and math to identify schools as either improving or declining over three consecutive years. We then compared the science achievement of students from these schools as measured by the ACT Science exams. Our findings from three consecutive cohorts, including thousands of high school students who attended 12th grade in 2008, 2009, and 2010 indicate that students attending improving schools identified by state administered standardized tests generally performed no better on a widely administered college entrance exam with tests in science, math and English. In 2010, students from schools identified as improving in English scored nearly one‐half of a point lower than their peers from declining schools on both the ACT Science and Math exams. We discuss various interpretations and implications of these results and suggest areas for future research. © 2012 Wiley Periodicals, Inc. J Res Sci Teach 49: 804–830, 2012  相似文献

A large number of American elementary school students are now studying science using the hands‐on inquiry curricula developed in the 1990s: Insights; Full Option Science System (FOSS); and Science and Technology for Children (STC). A goal of these programs, echoed in the National Science Education Standards, is that children should gain “abilities to do scientific inquiry” and “understanding about scientific inquiry.” We have studied the degree to which students can do inquiries by using four hands‐on performance assessments, which required one or three class periods. To be fair, the assessments avoided content that is studied in depth in the hands‐on programs. For a sample of about 1000 fifth grade students, we compared the performance of students in hands‐on curricula with an equal number of students with textbook curricula. The students were from 41 classrooms in nine school districts. The results show little or no curricular effect. There was a strong dependence on students' cognitive ability, as measured with a standard multiple‐choice instrument. There was no significant difference between boys and girls. Also, there was no difference on a multiple‐choice test, which used items released from the Trends in International Mathematics and Science Study (TIMSS). It is not completely clear whether the lack of difference on the performance assessments was a consequence of the assessments, the curricula, and/or the teaching. © 2006 Wiley Periodicals, Inc.

This paper sets out an argument and approach for moving beyond a primarily arts‐based conceptualization of cultural capital, as has been the tendency within Bourdieusian approaches to date. We advance the notion that, in contemporary society, scientific forms of cultural and social capital can command a high symbolic and exchange value. Our previous research [Archer et al. (2014) Journal of Research in Science Teaching 51, 1–30] proposed the concept of “science capital” (science‐related forms of cultural and social capital) as a theoretical lens for explaining differential patterns of aspiration and educational participation among young people. Here, we attempt to theoretically, methodologically, and empirically advance a discussion of how we might conceptualize science capital and how this might be translated into a survey tool for use with students. We report on findings from a survey conducted with 3658 secondary school students, aged 11–15 years, in England. Analysis found that science capital was unevenly spread across the student population, with 5% being classified as having “high” science capital and 27% “low” science capital. Analysis shows that levels of science capital (high, medium, or low) are clearly patterned by cultural capital, gender, ethnicity, and set (track) in science. Students with high, medium, or low levels of science capital also seem to have very different post‐16 plans (regarding studying or working in science) and different levels of self‐efficacy in science. They also vary dramatically in terms of whether they feel others see them as a “science person.” The paper concludes with a discussion of conceptual and methodological issues and implications for practice. © 2015 The Authors.

Teaching in urban schools, with their problems of violence, lack of resources, and inadequate funding, is difficult. It is even more difficult to learn to teach in urban schools. Yet learning in those locations where one will subsequently be working has been shown to be the best preparation for teaching. In this article we propose coteaching as a viable model for teacher preparation and the professional development of urban science teachers. Coteaching—working at the elbow of someone else—allows new teachers to experience appropriate and timely action by providing them with shared experiences that become the topic of their professional conversations with other coteachers (including peers, the cooperating teacher, university supervisors, and high school students). This article also includes an ethnography describing the experiences of a new teacher who had been assigned to an urban high school as field experience, during which she enacted a curriculum that was culturally relevant to her African American students, acknowledged their minority status with respect to science, and enabled them to pursue the school district standards. Even though coteaching enables learning to teach and curricula reform, we raise doubts about whether our approaches to teacher education and enacting science curricula are hegemonic and oppressive to the students we seek to emancipate through education. © 2001 John Wiley & Sons, Inc.

This study examined middle and high school students' perceptions of a weeklong science experience with nanotechnology and atomic force microscopy. Through an examination of student self assessments and their writing, the study allowed us to examine some of the issues that may contribute to discrepancies that are seen between European‐American and African‐American students in science. The results of the study showed that after instruction, African‐American students were significantly more likely to agree with the statement that “science involves mostly memorizing things and getting the right answer,” than European‐American students. In addition, European‐American students were significantly more likely to write their newspaper stories from a first person perspective than their African‐American peers. The results are discussed in light of the assessment task, students' interpretations of formal writing, cultural differences in the use of language in writing, and possible cultural differences in students' perceptions of the science experience. © 2007 Wiley Periodicals, Inc.

Science in schooling has for the first time been recently considered as a verified whole for the 10 or 12 of its compulsory years, rather than for a limited sector of schooling or for a particular group of students. This has also been occurring as part of a wider review and plan for the whole curriculum of schooling. A framework has been provided consisting of a matrix of strands of intended content for learning across a number of levels approximating the years of schooling. There is a sense and expectation of continuous progression in the learning of science. Earlier notions of progression in science curricula are explored and compared with what has now appeared in the national curricula in England and Wales, New Zealand and Australia. The notions of curriculum opportunity and curriculum purpose for science education are introduced as factors that would lead to a shift in the sense of progression from a focus on Science itself to an emphasis on the learners' changing need of Science as they progress through the years of schooling.

Changes in medical education have affected both curriculum design and delivery. Many medical schools now use integrated curricula and a systemic approach, with reduced hours of anatomy teaching. While learning anatomy via dissection is invaluable in educational, professional, and personal development, it is time intensive and supports a regional approach to learning anatomy; the use of prosections has replaced dissection as the main teaching method in many medical schools. In our graduate‐entry medical degree, we use an integrated curriculum, with prosections to teach anatomy systemically. However, to not exclude dissection completely, and to expose students to its additional and unique benefits, we implemented a short “Dissection Experience” at the beginning of Year 2. Students attended three two‐hour anatomy sessions and participated in dissection of the clinically relevant areas of the cubital fossa, femoral triangle, and infraclavicular region. This activity was voluntary and we retrospectively surveyed all students to ascertain factors influencing their decision of whether to participate in this activity, and to obtain feedback from those students who did participate. The main reasons students did not participate were previous dissection experience and time constraints. The reasons most strongly affecting students' decisions to participate related to experience (lack of previous or new) and new skill. Students' responses as to the most beneficial component of the dissection experience were based around practical skills, anatomical education, the learning process, and the body donors. We report here on the benefits and practicalities of including a short dissection experience in a systemic, prosection‐based anatomy course.

Ultrasonography is a noninvasive imaging modality, and modern ultrasound machines are portable, inexpensive (relative to other imaging modalities), and user friendly. The aim of this study was to explore student perceptions of the use of ultrasound to teach “living anatomy”. A module utilizing transthoracic echocardiography was developed and presented to undergraduate medical, science, and dental students at a time they were learning cardiac anatomy as part of their curriculum. Relevant cardiac anatomy was explored on a student volunteer and images were projected in real‐time to all students via an AV projection system. Students were asked to complete a questionnaire about the learning experience and were given the opportunity to provide open feedback. The students' evaluations of this learning experience were very positive. They agreed or strongly agreed that it was an effective way to teach anatomy (90% medical; 77% dental; 100% science) and that it was incorporated in a way that promoted reinforcement of the lecture material (83% medical; 76% dental; 100% science). They agreed or strongly agreed with statements that the experience was innovative (93% medical; 92% dental; 100% science) and stimulated interest in the subject matter (86% medical; 75% dental; 96% science), and that they would like to see more modules, exploring other anatomical sites, incorporated into the curricula (83% medical; 72% dental; 100% science). We believe that ultrasound could be a useful tool, in conjunction with traditional teaching methods, to reinforce the learning of anatomy of a variety of different undergraduate student groups.

The teaching of science through activities that emphasize design and technology has been advocated as a vehicle for accomplishing science for all students. This study was situated in an inner7‐city neighborhood school populated mainly by African American students from life worlds characterized by poverty. The article explores the discourse and practices of students and three coteachers as a curriculum was enacted to provide opportunities for students to learn about the physics of motion through designing, building, and testing a model car. Some students participated in ways that led to their building viable model cars and interacting with one another in ways that suggest design and technological competence. However, there also was evidence of resistance from students who participated sporadically and refused to cooperate with teachers as they endeavored to structure the environment in ways that would lead to a deeper understanding of science. Analysis of in‐class interactions reveals an untapped potential for the emergence of a sciencelike discourse and diverse outcomes. Among the challenges explored in this article is a struggle for respect that permeates the students' lives on the street and bleeds into the classroom environment. Whereas teachers enacted the curriculum as if learning was the chief goal for students, it is apparent that students used the class opportunistically to maintain and earn the respect of peers. © 2001 John Wiley & Sons, Inc.

Our research project was guided by the assumption that students who learn to understand phenomena in everyday terms prior to being taught scientific language will develop improved understanding of new concepts. We used web‐based software to teach students using a “content‐first” approach that allowed students to transition from everyday understanding of phenomena to the use of scientific language. This study involved 49 minority students who were randomly assigned into two groups for analysis: a treatment group (taught with everyday language prior to using scientific language) and a control group (taught with scientific language). Using a pre–post‐test control group design, we assessed students' conceptual and linguistic understanding of photosynthesis. The results of this study indicated that students taught with the “content‐first” approach developed significantly improved understanding when compared to students taught in traditional ways. © 2008 Wiley Periodicals, Inc.
