This paper examines the notion of laws in chemistry. Vihalemm (Found Chem 5(1):7–22, 2003) argues that the laws of chemistry are fundamentally the same as the laws of physics they are all ceteris paribus laws which are true “in ideal conditions”. In contrast, Scerri (2000) contends that the laws of chemistry are fundamentally different to the laws of physics, because they involve approximations. Christie (Stud Hist Philos Sci 25:613–629, 1994) and Christie and Christie (Of minds and molecules. Oxford University Press, New York, pp. 34–50, 2000) agree that the laws of chemistry are operationally different to the laws of physics, but claim that the distinction between exact and approximate laws is too simplistic to taxonomise them. Approximations in chemistry involve diverse kinds of activity and often what counts as a scientific law in chemistry is dictated by the context of its use in scientific practice. This paper addresses the question of what makes chemical laws distinctive independently of the separate question as to how they are related to the laws of physics. From an analysis of some candidate ceteris paribus laws in chemistry, this paper argues that there are two distinct kinds of ceteris paribus laws in chemistry; idealized and approximate chemical laws. Thus, while Christie (Stud Hist Philos Sci 25:613–629, 1994) and Christie and Christie (Of minds and molecules. Oxford University Press, New York, pp. 34--50, 2000) are correct to point out that the candidate generalisations in chemistry are diverse and heterogeneous, a distinction between idealizations and approximations can nevertheless be used to successfully taxonomise them. 相似文献

This contribution looks at a series of qualitative and quantitative investigations on the study success and study behavior of so-called non-traditional students. Of particular interest are two aspects: the combination of qualitative and quantitative findings, which are mutually complementary and in a sense present plausible corrections for one-sided observations, and controlled observations over a long period of time, as the first studies were carried out within the framework of an international study in 1998 and the last one within the framework of a project sponsored by the German Research Foundation (DFG) in 2007. This longer time period certainly increases the plausibility of the cautious diagnoses made, which attempt to capture the relevant changes in this field of research. Such mixed methods research (Derzin 1970, 1989; Flick 1992) – i.e. the link between quantitative and qualitative research and survey methods often termed “triangulation” (cf. Prein/Kelle/Kluge 1993; Flick 1995) – has the advantage that a complex field of research can be scanned using different instruments and through a type of “convergence model” (Jacob 2001) the data won from different methods can be used to mutually validate the results. The qualitative material used in this study comes from theoretical sampling (cf. Glaser 1965; Strauss/Corbin 1996) of data from six German higher education institutions from two points in time (1998 and 2005; n=2x c. 400 surveyed respondents). The quantitative analysis, which was especially carried out for our study, profits from the fact that 2500 interested people responded to our recruitment search for biographic-narrative interviews. This group of people was then asked to participate in a special online survey in 2007 – a cooperative initiative in which around one third of the initial respondents took part. That does, however, mean that the quantitative study is not representative. Our overall research design remains complex, but retains an exploratory character 相似文献

This article is an attempt to contribute to the conversation about “go[ing] beyond all kinds of binary thinking” (Lenz Taguchi, Going beyond the theory/practice divide in early childhood education: introducing an intra-active pedagogy, 2010, p. 50), especially the binary which positions “adults” and “children” as being powerful and powerless, respectively, in educational settings. It is also a personal reflection on “naming.” At the center of the reflection are two literary works, the picture book by Henkes, Chrysanthemum (1991), and the novel by Rousseau, émile, ou l’education (1762a). The central metaphor of émile—that of the developing child as organically unfolding, like a flower—is deconstructed by the plot involving two flower-named characters in Chrysanthemum. These characters are the protagonist, Chrysanthemum, and her music teacher, Delphinium Twinkle. Two acts of “naming” are considered: the literal act of naming a newborn baby and the abstract concept of “naming” [or labeling] a particular time in the life of a human being: “Childhood” (Cannella, Deconstructing early childhood education: social justice and revolution, 1997). 相似文献

Neoliberalism is a loosely knit bricolage from economics, politics, and various forms of reactionary populism that can be envisioned as a kind of epistemic frame in which largely counterrevolutionary forces engage in the creative destruction of institutional frameworks and powers, forging divisions across society that include labor and social relations (Harvey, A brief history of neoliberalism, 2009). Such “creative destruction” implies that neoliberalism is actually a reactionary “catalog of mind” (Robin, The reactionary mind: Conservatism from Edmund Burke to Sarah Palin, 2011, p. 17); that when believers engage in reactions to programs and ideas which represent what Bourdieu (Acts of resistance: Against the tyranny of the market, 1998) called “the left hand of the state” (typically represented by teachers, judges, social workers), one result has been the “involution of the state” (p. 34) and the “destruction of the idea of public service” (Bourdieu, The abdication of the state. In P. Bourdieu (Ed.), The weight of the world: Social suffering in contemporary society, 1999, p. 182). We examine neoliberalism using Shaffer’s (Int J Learn Media 1(2):1–21, 2009) concept of an “epistemic frame” based on the epistemic frame hypothesis that suggests that a community of practice has a culture, and that the collection of values, skills, knowledge, and identity form the “epistemic frame” (p. 4). An epistemic frame has a kind of grammar and structure comprised of people’s thoughts and actions, reinforced by the ways that people see themselves, the values to which they hold, and the epistemology that binds together their agenda. The purpose of our analysis is to create a praxis for what has been termed Regressionsverbot, which is defined as “a ban on backward movement with respect to social gains at the European level” (Bourdieu, Acts of resistance: Against the tyranny of the market, 1998, p. 41). In the form of cases from the United States, the United Kingdom, and the United Arab Emirates, neoliberal initiatives are examined, unpacked, and interrogated. 相似文献

This paper examines the history of welfare policy discourse in the United States since the publication of the “Moynihan Report” (1967) and traces its implications for contemporary education policy research. The central thesis is that an overemphasis on “parents” historically invites unwarranted assumptions about autonomy and responsibility, which obfuscates fundamental questions of justice. Children are consequently punished for their parents’ perceived indiscretions. To militate against this tendency the author employs recent feminist critiques of Rawls’s methodology in A Theory of Justice (1999) to reconceptualize the “Original Position” as a mother’s womb in an effort to redirect focus from parents to children. Through this revision, policy discourse can potentially be shifted to more nearly mirror the reasoning applied in Plyler v Doe (1982), which emphasizes finally that children cannot be punished for their parents’ indiscretions. 相似文献

Children’s picture books that recreate, parody, or fictionalize famous artworks and introduce the art museum experience, a genre to which I will refer as “children’s art books,” have become increasingly popular over the past decade. This essay explores the pedagogical implications of this trend through the family program “Picture Books and Picture Looks” conducted at the Art Institute of Chicago. Program sessions were observed to learn the extent to which picture books featuring the painting A Sunday on La Grande Jatte—1884 (Seurat) informed and impacted children’s experiences with the original artwork. The books Katie’s Sunday Afternoon (Mayhew, 2005), Babar’s Museum of Art (De Brunhoff, 2003), and Willy’s Pictures (Browne, 2000) provided the foundation for the program. In addition to these three books, The Dot (Reynolds, 2003), which does not include a reference to La Grande Jatte (Seurat, 1884–1886), acted as a “control” variable. This research demonstrates that while most picture books can be used to establish a level of comfort in an environment that is new to children, those that directly referenced the painting provided a base level of knowledge from which children could confidently draw upon encountering the original work. The research further indicated that, when used in conjunction with original artworks, children’s art books provide unique and distinct entry points for talking about art. The inclusion of artwork in children’s picture books elicits an enthusiasm and recognition that enhances the museum experience, and such books can be effective tools for enabling reflective, imaginative experiences with art. 相似文献

Through a critical cultural assets model, the authors use the methodological practices of collaboration, community site visits, document analysis, and interviews with cultural insiders to explore schools’ continued rejection of academic belonging for people from “othered” communities. They explore the case of Samoan youth—a marginalized cultural group—to contest the shared belief that school-based citizenry is an educational impossibility. Interview data with Samoan elders is analyzed using Consensual Qualitative Research methods (Hill et al. in Couns Psychol 24(4):517–572, 1997). They present themes of cultural capacities and academic disconnection to imagine a school context for the integration of cultural assets for “othered” youth (Kliewer and Biklen in Teach Coll Rec 109(12):2579–2600, 2007; Kliewer et al. American Educ Res Assoc J 3(2):163–192, 2006). 相似文献

Science education has experienced significant changes since the mid-20th century, most recently with the creation of STEM curricula (DeBoer 1991; Yager 2000). The emergence of the World Wide Web as a tool in research and discovery offers Pre-K-12 science education an opportunity to share information and perspectives which engage students with the scientific community (Zoller 2011). Students are able to access open, transparent sites creating common resources pools and autonomous working groups which can be used for shared problem solving. Science teachers should carefully build web 2.0 technology into their practice based on a changing pedagogy. Instead of focusing on teaching rule-based concepts and processes in which the teacher’s role is that of expert, education should be focusing on possibilities of the web both in scientific research and understanding. In addition, web-focused education can also help remake scientific product as a public good in the lives of both science researchers and science consumers. 相似文献

The transition from the industrial age to the information age has happened and is still happening in our society (Duffy, 2009). However, our current educational systems still operate based on the needs of the industrial-age society (Watson, Watson, & Reigeluth, n.d), making them among the least impacted organizations (Reigeluth & Joseph, 2002). This misalignment between schools and society takes the form of a discrepancy between what and how we teach students in schools and how schools are organized and operated (Banathy, 1991; Hargreaves, 1999; Wagner et al., 2006). Educational systems should address current students’ needs to facilitate their learning process and better preparethem for their future lives in society (Collins & Halverson, 2009). In this article, we explain how we envision the new paradigm of education and what roles educational technologists should play to help transform educational systems to this new paradigm. 相似文献

Societal benefit depends on the general public’s understandings of biotechnology (Betsch in World J Microbiol Biotechnol 12:439–443, 1996; Dawson and Cowan in Int J Sci Educ 25(1):57–69, 2003; Schiller in Business Review: Federal Reserve Bank of Philadelphia (Fourth Quarter), 2002; Smith and Emmeluth in Am Biol Teach 64(2):93–99, 2002). A National Science Foundation funded survey of high school biology teachers reported that hands-on biotechnology education exists in advanced high school biology in the United States, but is non-existent in mainstream biology coursework (Micklos et al. in Biotechnology labs in American high schools, 1998). The majority of pre-service teacher content preparation courses do not teach students appropriate content knowledge through the process of inquiry. A broad continuum exists when discussing inquiry-oriented student investigations (Hanegan et al. in School Sci Math J 109(2):110–134, 2009). Depending on the amount of structure in teacher lessons, inquiries can often be categorized as guided or open. The lesson can be further categorized as simple or authentic (Chinn and Malhotra in Sci Educ 86(2):175–218, 2002). Although authentic inquiries provide the best opportunities for cognitive development and scientific reasoning, guided and simple inquiries are more often employed in the classroom (Crawford in J Res Sci Teach 37(9):916–937, 2000; NRC in Inquiry and the national science education standards: a guide for teaching and learning, 2000). For the purposes of this study we defined inquiry as “authentic” if original research problems were resolved (Hanegan et al. in School Sci Math J 109(2):110–134, 2009; Chinn and Malhotra in Sci Educ 86(2):175–218, 2002; Roth in Authentic school science: knowing and learning in open-inquiry science laboratories, 1995). The research question to guide this study through naturalistic inquiry research methods was: How will participants express whether or not an authentic inquiry experience enhanced their understanding of biotechnology? As respondents explored numerous ideas in order to develop a workable research question, struggled to create a viable protocol, executed their experiment, and then evaluated their results, they commented on unexpected topics regarding the nature of science as well as specific content knowledge relating to their experiments. Four out of five participants reported they learned the most during authentic inquiry laboratory experience. 相似文献

The current study developed the concept of fear of success that was originally examined by Martina Horner (1970; Journal of Social Issues, 28(2), 157–175, 1972). The key dimension in Horner’s (1970; Journal of Social Issues, 28(2), 157–175, 1972) studies was gender. The key dimension in the current study was social class. It was hypothesised that individuals from socio-economically disadvantaged backgrounds fear that, for them, success will lead to alienation from their community, and the loss of identity and loss of overall sense of belonging within their culture. The majority of the previous studies were based in the USA and examined fear of success using objectivist conceptions of success and quantitative methodologies. Eleven participants took part in the current study, three males and eight females. Two-phase qualitative interviewing was employed as the primary source of data collection in an attempt to gain a deeper understanding of the constructions and experiences of the participants in relation to success. The majority of participants believed that they would have to make vast life changes, in order to facilitate their views of desired success. The participants’ fear was rooted in what they perceived as the “consequences of success”. These participants occupied a “trade-off mindset”; for these young people, success meant leaving their family, friends, community and culture behind. The thought of losing this “connection” and sense of belonging was expressed with noticeable anxiety. 相似文献

Because trucks aren’t bicycles: orthographic complexity as an important variable in reading research
Severe enduring reading- and writing-accuracy difficulties seem a phenomenon largely restricted to nations using complex orthographies, notably Anglophone nations, given English’s highly complex orthography (Geva and Siegel, Read Writ 12:1–30, 2000; Landerl et al., Cognition 63:315–334, 1997; Share, Psychol Bull 134(4):584–615, 2008; Torgesen and Davis, J Exp Child Psychol 63:1–21, 1996; Vellutino, J Learn Disabil 33(3):223, 2000). They seem rare in transparent orthography nations such as Finland, which use highly regular spelling and few spelling rules beyond letter sounds, and most children read and write with impressive accuracy by the end of Year 1 (Holopainen et al., J Learn Disabil 34(5):401–413, 2001; Seymour et al., Br J Psychol 94:143–174, 2003; Spencer and Hanley, Br J Psychol 94(1):1–29, 2003; J Res Read 27(1):1–14, 2004). Orthographic complexity has strong and diverse impacts on reading, writing and academic development (Aro, Learning to read: The effect of orthography, 2004; Galletly and Knight, Aust J Learn Disabil 9(4):4–11, 2004; Aust Educ Res 38(3):329–354, 2011). Despite these strong effects, orthographic complexity is rarely included as a variable in reading research studies considering evidence from both Anglophone (complex orthography) and transparent-orthography readers, or included in discussion of factors influencing results. This paper discusses the differences in reading-accuracy development and difficulties evidenced in studies of Anglophone (complex-orthography) and transparent-orthography readers. It then explores instances of orthographic complexity not being considered in studies where it may have impacted results. This disregarding of orthographic complexity as a variable in research studies appears an oversight, one likely to be contributing to continuing confusion on many aspects of reading and writing development in both healthy- and low-progress readers. Needs for research in these areas are discussed. 相似文献

This paper uses Tight (High Educ Res Dev 23(4):395–411, 2004; High Educ Res Dev 31(5):723–740, 2012; High Educ Res Dev 32(1):136–151, 2013)’s journal analysis and review framework to review a sample of 497 journal articles on researches concerning international students over the past 30 years. It was found that a majority of the articles focus on the students’ in-campus, academic and social experience. Even with different conceptualisation of the terms “international student” and “international student mobility”, international students undergo similar challenges throughout their sojourn duration, and much of the responsibilities in managing international students fall on universities and respective faculty members within the institutions. It might seem as if we are going in circles in terms of the issues and concerns in managing international students, but the silver lining out of this observation is the increased ethnical awareness among countries and higher education institutions in hosting and safeguarding the students throughout their international higher education experience, albeit rather slowly. The analysis brings to attention how much have we achieved in internationalisation of higher education in general and international student-related research in particular, and the potential for greater expansion and focus on managing the student population within a comprehensive “life cycle” approach. 相似文献

Innovative professionals rely on a specific ways of thinking to solve the nonstandard problems that come up in practice (Goodwin, Am Anthropol 96(3):606–633, 1994; Schön, The reflective practitioner: how professionals think in action, 1983; Educating the reflective practitioner: toward a new design for teaching and learning in the professions, 1987; Sullivan, Work and integrity: the crisis and promise of professionalism in America, 1995). The professions have reproductive practices for transmitting these ways of thinking, such as practica (Schön, Educating the reflective practitioner: toward a new design for teaching and learning in the professions, 1987). In this paper, we examine the learning relationship between a mentor and team of college students through an ethnographic study of a game design practicum at a European arts school. To examine the role that the mentor played in this practicum, we use two theoretical constructs. Epistemic frames—the configurations of the skills, knowledge, identities, values, and epistemologies that professionals use to think in innovative ways—provide a model for examining professional expertise (Shaffer, Comput Educ, 46(3):223–234, 2006a). Epistemic network analysis (ENA) (Shaffer et al., Int J Learn Media, 1(2):33–53, 2009) is a method for quantifying changes in epistemic frames (Shaffer, The bicycle helmets of “Amsterdam”: computer games and the problem of transfer, 2010). Our results here suggest that the mentor leads the team on a path that illuminates the nature of learning to think professionally, as well the function of a mentor in that process. We argue that the mentor, rather than providing a direct map to a professional vantage point, scaffolds aspects of the epistemic frame of game design that, in turn, aid in the development of a more professional frame. Using ENA to understand the way that mentors help coach learners to develop epistemic frames should be useful for further studies of professional education, as well as for studies of apprenticeship-based programs for youth. 相似文献

Photovoice is a participatory action research tool that is grounded in the literature for critical consciousness (Wang & Burris, 1997). Four creative high school girls who reported struggles with mathematics were given cameras and asked to take photographs to answer the following questions: (1) What is mathematics? (2) What is your ideal learning environment? (3) What things impede your learning of mathematics? Within-case and cross-case analyses of the photographs and interview responses were conducted. Each individual case was analyzed using the work of Belenky, Clinchy, Goldberger, and Tarule (Women’s Ways of Knowing, 1986) who investigated women’s epistemological perspectives. The girls were either silenced (disconnected from the mathematical knowledge of the teacher), received (lacked confidence to do mathematics independently), or “fragily” subjective (viewed mathematical knowledge as personal rather than imparted by the teacher) knowers of mathematics. The use of photovoice has the power to facilitate the nurturing of silence as it moves toward the “roar which is on the other side of silence” (Belenky et al., 1986, p. 4). 相似文献

This article will particularly focus on Norway and the consequences for academic work. Frequently in studies of academic work, focus has been on academics’ individual autonomy and to what extent the latter is challenged (Altbach in Ann Am Acad Pol Soc Sci 448:1–14, 1980; Shattock in High Educ 41:27–47, 2001). One of the shortcomings in literature dealing with academic workplace is lack of attention paid to the emerging division of work generated by an increasing differentiation of the academic profession (Musselin in Knowledge Matters, The public mission of the research university, 2011). In order to better address complexities and dynamics that surround academic work, the article will in particular examine whether academic work is subject to an increasing specialization and collectivization. In our attempt to observe changes in the practices of academic work, particular interest is given to “how the organization of an academic enterprise affects academic work” (Blau in The organization of academic work. Transaction Publishers, New Brunswick, 1994:8). Inspired by organizational theorists such as Brunsson and Olsen in The reforming organization. Brunsson and Olsen (The reforming organization. Fagbokforlaget, Bergen, 1997) we also want to attend to the relations between organizational change and academic work. Here we address the relationship between formal organization and informal organization which is likely to develop as decoupled structures—one adapted to institutionalized norms of society and the other for coordinating activities. Furthermore, there are tendencies suggesting that universities are becoming less special as an organization (Musselin in Key challenges to the academic profession. INCHER-Kassel, Paris, 2007) and converge to more general organizational characteristics by constructing dimensions of organizations such as identity, hierarchy and rationality (Brunsson and Sahlin-Andersson in Constructing organizations: the example of public sector reform, Organization Stud 21:4, 2000). In this article we are mainly interested in how hierarchy is constructed enabling coordination by an “authoritative centre” (Brunsson and Sahlin-Andersson in Constructing organizations: the example of public sector reform, Organization Stud 21:4, 2000:726) and how it interferes with traditional forms of organizing the university. This calls for a concern to whether the specificity of academic work, built of the mainly individual exercise of a large diversity of tasks, remains a key characteristic for organizing academic activities at universities. Empirically this article studies changes in academic work regarding new patterns in organizing research funding and doctoral education in Norway that emerged in the last decade. Like in other European countries, new policies for research funding and doctoral education have led to the creation of new organisational structures within Norwegian HEIs, namely research centres and doctoral schools. 相似文献

There is growing research interest in the challenges and opportunities learners face in representing scientific understandings, processes and reasoning. These challenges include integrating verbal, visual and mathematical modes in science discourse to make strong conceptual links between representations and classroom experiences. Our paper reports on a project that aimed to identify practical and theoretical issues entailed in a representation-intensive approach to guiding students’ conceptual learning in science. We focus here on a teacher developing students’ understanding of the formation of ions and molecules. We argue that the representations produced by students in this process met the criteria for representational competence proposed by diSessa (Cognition and Instruction, 22, 293–331, 2004) and Kozma & Russell (2005). The students understood that an effective representation needed to show relevant information, focus on pertinent points, be self-sufficient in its claims about the topic and provide coherent links between different parts of the representation. The final activity showed that their representations reached Kozma & Russell’s (2005) highest level of competence, where the students were able to use specific features of their representations to critique their suitability for explaining bonding and were able to show how their representation linked to the periodic table as a representation. We conclude by considering the implications of these findings. 相似文献
