Advanced Placement (AP) Chemistry and the National AP Chemistry Examination are both critical to secondary level institutions nationwide. The use of a national embossing stamp to attest to successful completion of an AP Chemistry course and exam to ensure college credit is a novel idea worth consideration. Moreover, the concept could be expanded to all AP science disciplines conducting laboratory exercises.  相似文献

The purpose of this paper is to investigate the argumentative structure of students’ arguments using argumentation schemes as an instrument for reconstructing the missing premises underlying their reasoning. Building on the recent literature in science education, in order for an explanation to be persuasive and achieve a conceptual change it needs to proceed from the interlocutor’s background knowledge to the analysis of the unknown or wrongly interpreted phenomena. Argumentation schemes represent the abstract forms of the most used and common forms of human reasoning, combining logical principles with semantic concepts. By identifying the argument structure it is possible to retrieve the missing premises and the crucial concepts and definition on which the conclusion is based. This method of analysis will be shown to provide the teacher with an instrument to improve his or her explanations by taking into consideration the students’ intuitions and deep background knowledge on a specific issue. In this fashion the teacher can advance counterarguments or propose new perspectives on the subject matter in order to persuade the students to accept new scientific concepts.  相似文献

William Wordsworth was the representative of the British "Lake poets" In his poems he aimed at simplicity and purity of the language,fighting against the conventional forms of the 18th century poetry.He transformed his observation of the landscape into the revelation of the beauty of nature in poetry,and thus expressed his nature philosophy.In this article the author briefly analyses the organization of his poem: "Ode: Intimation of Immortality" and mainly elaborates her understanding of the poet’s na-ture-philosophy in four points:(a) Man is sensitive to all natural influences in childhood.(b) Nature has a moral and spiritual sig-nificance and helps the poet understand the mystery of human life.(c) Life is but a stage.(d) All good poetry is the spontaneous overflow of powerful feelings;it takes its origin from emotion recollected in tranquility.  相似文献

In line with broader politics of change at the national level, the Morales government aims at a radical restructuring of the governance mechanisms for the teacher education sector and a socio-political redirection of its curriculum, as teachers are perceived to be potential agents for decolonization and for developing social justice—or vivir bien (to live well). Morales’ policies are not uncontested, and the tense socio-political state of affairs and political power plays are reflected in Bolivia’s normales, teacher education colleges. They have become a socio-political battlefield where political affiliations, union strategies, and historically embedded institutional cultures all influence the way new generations of teachers are trained, and the way former and current policy initiatives are mediated and adopted. Given the complex and historically embedded socio-political context of struggles and tensions at and around the institutional level, the government still has a long way to go to change the continuing habits of the normales and to put its government’s new ideals of transformation and decolonization into practice.  相似文献

Understanding: ‘Knowledge’, ‘Belief’ and ‘Understanding’   总被引:1,自引:0,他引:1  
The following paper is intended as an exercise in friendly criticism of one of Harvey Siegel's and Mike Smith's (Knowing, Believing and Understanding, this volume). I'm in substantial sympathy with the general thrust of their paper and my remarks merely provide some criticism of their discussion's conceptual coherence and clarity and a correspondingly slightly adjusted version of what they have to say. My focus is limited to the conceptions of knowledge, belief and understanding and their inter-relationships in terms of which they offer suggestions to science educators.  相似文献

This article discusses urban educators’ views of their teaching experiences. The article is based upon survey research conducted with teachers in two poor, urban districts during the 2005–2006 academic year. The teachers reported a variety of positive and negative views regarding their classrooms, their students, and the students’ social worlds. The data illustrate the importance of classroom processes for the teachers, and how they believed that their students’ social locations, behaviors, and attitudes impede the delivery of educational content. We believe this research raises interesting challenges regarding the need for urban educators to incorporate students’ perspectives into both instructional processes and curriculum content. Furthermore, this research should contribute to the empirical foundation needed for the creation of better teacher preparation programs.  相似文献

As part of a large‐scale study of the ability of 94 secondary schools to promote academic achievement, case studies of six outlier schools were conducted and headteachers (principals) and their deputies were questioned about the processes of effectiveness. The analysis of their responses ‐ grouped by the performance of their school (measured by value added analyses of three years of public examination results) as effective, ineffective or mixed ‐ reveals considerable support for previously cited characteristics of effective schooling. Despite the limitations imposed by a reliance on the use of retrospective accounts, the study takes forward the field of school effectiveness in its search for generalisable findings and coherent theory.

ABSTRACT

Researchers have concluded that policy implementation is a process of mutual adaptation between policies and implementers. Our study draws attention to that relationship, especially with respect to policies that challenge assumptions about sex, gender, and sexuality. We focus on how six administrators in one United States school district understood ‘the work’ of bringing the district’s Guidelines for Supporting Transgender and Gender Nonconforming Students into practice. Our analysis of interview data focused these questions: How do administrators describe their motivation and commitment to engage in the work? What puzzles of practice do participants name? How do they talk about the work of implementation? What does that work mean/involve in everyday practice? What were their roles? We found that implementation was locally defined and enacted; participants’ sense-making, their roles in enacting the Guidelines, and the puzzles they negotiated were influenced by their unique contexts. We share examples of diverse cases in an effort to create policy knowledge.  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

A group of experienced secondary school teachers used a novel learning theory as a resource for planning and carrying out their teaching of a difficult economic concept. Their students mastery of this concept after a series of three lessons was compared with the mastery of the same concept by students who were taught by another group of teachers under the same conditions except for the use of the theory. The difference in learning outcomes was extreme. Observations of what was happening in the classrooms showed subtle but decisive differences correlated with the differences in outcome. These differences were interpreted in terms of the theory used by the first group, and the results seem to give support to the theoretical claim that for any specific object of learning there is a necessary pattern of variation and invariance that the learners must experience in order to appropriate the object of learning in question and thus by bringing out that pattern in the learning situation, the likelihood of that object of learning being appropriated is enhanced. Furthermore, this study shows how the understanding of the simultaneous change in the supply of and the demand for a certain good affects its market price can be brought about in a powerful way.  相似文献

This paper offers a discussion of the literature of an under-developed area of early years research—the exploration of childminding or home-based childcare and the contribution which this form of provision makes for children and families. Despite growing interest in childminding at the policy level and some international research on understanding home-based childcare settings and practices, there remains a relative dearth of studies conceptualising and reviewing the extant literature. This paper addresses this gap by presenting the findings of a comprehensive database search for literature and a review of published international work from 1990 to 2013. It offers a conceptual analysis of the notion of “home-based childcare”, with a focus on understanding caregivers’ practices, and the key issues and debates that characterise the field. The paper argues that home-based childcare not only offers a specialist type of service as family support, especially for vulnerable families, but that it provides a form of pedagogical approach to children’s developmental and educational outcomes that is distinct from any other types of early years care.  相似文献

Whilst within universities, research on rather than with children/pupils is a well-established methodology, this paper reports on teachers’ responses to a schools and university-based partnership project, ‘Pupils as Research Partners in Primary (PARPP), which works to co-create pupil-led research opportunities for pupils in research projects informed by pupils’ experiences in primary schools. A previous paper, French and Hobbs, [(2017). “‘So How Well Did It Really Go’? Working with Primary School Pupils as Project Evaluators: A Case Study.” TEAN Journal 9 (1): 56–65] reported on how one PARPP project had a beneficial effect on pupils and their school environment. For this paper the project team interviewed a number of teachers whose pupils in the partner schools were involved in the pilot study phase of the project. Specifically, the teachers were interviewed to ascertain if the involvement of pupils, as lead researchers in projects exploring various aspects of the school environment, had impacted on their perceptions of pupil-led research. Findings suggest that the experiences of teachers in schools where PARPP projects had taken place had led them to re-evaluate the practicality and desirability of encouraging pupils to actively to research their school environments.  相似文献

Abstract

The later works of Charles Sanders Peirce (1839–1913) offer an extended metaphor of mind and a rich conception of the dynamics of knowledge and learning. After a ‘rhetorical turn’ Peirce develops his early ‘semiotics’ into a more general theory of sign and sign use,while integrating his pragmatism, phenomenology, and semiotics. Therefore, in this article I bring Peirce’s notion of semiosis—the sign’s action—to the forefront. In doing so, I hope to disclose how Peirce’s rhetorical turn not only opens up towards a richer conception of the dynamics of knowledge and learning, but also invites a shift of perspective from the psychological processes of learning to the semeiotic processes that characterizes the very dynamics of knowledge production.  相似文献

This paper seeks to examine current policy reforms that situate education as a means of addressing social inclusion. Borrowing from the work of Popkewitz and Lindblad, the paper takes the form of a cross‐disciplinary literature review that informs understanding of the relationship between educational governance and social inclusion/exclusion in policy research in Australia. To do so, the author examines the assumptions, omissions and contradictions in policy direction via two problematics – the engagement problematic and the early intervention and prevention problematic – to emphasise how policy discourse produces ways of thinking about inclusion/exclusion. The author argues that discourses of engagement and intervention and prevention reinscribe each other, acting as a palimpsest which produces notions of the ‘proper’ family and ‘proper’ participation. These notions of propriety ironically exclude particular types of individuals and families by situating them outside of possibilities for ‘success’ in social and systemic participation. Therefore, the author seeks to examine the ‘systems of reason’ that enable these discursively produced notions of propriety to become normalised.  相似文献
