Learning science interpreted in existing theoretical frameworks often means that students are assimilated, accommodated or enculturated from the entity of the vernacular world to the entity of the scientific world. However, there are some unsolved questions as to how students can best learn purely a new language or new knowledge of science. The purpose of this study is to conduct microanalysis of moment-to-moment interactions in order to understand how science language is taught and learned in details. Informed by Bakhtin’s dialogism, the analysis indicates that learning science is a process of appropriating authoritative discourse into internally persuasive discourse. Based on our analysis and findings, we propose the framework of discursive evolution to describe the process of teaching and learning the language of science. Four different stages of discursive evolution are identified to demonstrate the discursive changes during the course of science teaching and learning discourse: (a) using deictic references to connect scientific terminologies, (b) understanding science terminologies through its derivatives, (c) communicating science practices conventionally through science terminologies, and (d) communicating science practices innovatively through mutated science terminologies. The findings suggest that science teaching and learning comprise a heterogeneous process which draws on both science and non-science language and is a constantly evolving process. Understanding teaching and learning as a heterogeneous and constantly evolving process allows us to reunite the roles of teachers and students as mutually responsible collaborators rather than science knowledge givers and consumers.  相似文献

To date, the concept of English for Specific Purposes has brought about a great impact on English language learning across various disciplines, including those in science education. Hence, this review paper aimed to address current English language learning in the science disciplines through the practice of computer-assisted language learning to identify the use of learning technologies in science-based literacy. In the literature review, the researchers found that science-based literacy instruction shares many pedagogical aims with English language teaching in terms of reading, writing, listening and speaking, allowing it to be classified as English for Scientific Purposes (EScP). To answer the research questions, the researchers conducted the survey by extracting related articles and teaching examples from the Web of Science. In the search procedure, the researchers used the keywords science OR scientific AND technolog* OR comput* in ten selected journals of social science citation index. Only articles which are specified as journal articles rather than other document types were included. After compiling the corpora, the researchers compared the trends, methodologies and results of EScP instruction in science education. The implications of this study include the opportunities, advantages and challenges for EScP instruction in science education to further develop better educational approaches, adopt new technologies, as well as offer some directions for researchers to conduct future studies.  相似文献

The term scientific literacy is defined differently in different contexts. The term literacy simply refers to the ability for one to read and write, but recent studies in language literacy have extended this definition. New literacy research seeks a redefinition in terms of how skills are used rather than how they are learned. Contemporary perspectives on literacy as a transfer of learned skills into daily life practises capture the understanding of what it means to be scientifically literate. Scientific literacy requires students to be able to use their scientific knowledge independently in the everyday world. Some models for teaching towards scientific literacy have been suggested including inquiry‐based learning embedded in constructivist epistemologies. The inquiry‐based model is posited to be effective at bringing about in‐depth understanding of scientific concepts through engaging students’ preconceptions. In order to establish whether directly engaging students’ preconceptions can lead to in‐depth understanding of the science of HIV/AIDS, a case study was designed to elucidate students’ prior knowledge. From questionnaires and classroom observations, Ugandan Grade 11 students’ persistent preconceptions were explored in follow‐up focus group discussions. The inquiry process was used to engage students with their own perceptions of HIV/AIDS during the focus group discussions. Findings suggest that students need to dialogue with each other as they reflect on their beliefs about HIV/AIDS. Dialogue enabled students to challenge their beliefs while making connections between ‘school’ and ‘home’ knowledge.  相似文献

The paper emphasizes the crucial importance of transdisciplinary approach to qualitative research methodology in teaching and learning contexts involving highly stigmatized minority languages. Autoethnography and participatory action research are herein employed as constructive, critical, qualitative methodological procedures relevant to transdisciplinary research on minority languages in applied linguistics. An international project on teaching and learning Romani, QUALIROM, is used as a case study in order to emphasize the fact that mere theoretical knowledge and professional expertise are important but not sufficient for successful implementation and sustainability of outcomes in this field of linguistic research. The analysis suggests that socially engaged minority language learning and teaching projects should be understood as transdisciplinary, collaborative activities that transcend academic boundaries, and in which research participants create a number of interactive contexts within project-oriented communities of practice aimed at reshaping dominant social relations and practices.  相似文献

This study examined the role of computer-supported knowledge-building discourse and epistemic reflection in promoting elementary-school students’ scientific epistemology and science learning. The participants were 39 Grade 5 students who were collectively pursuing ideas and inquiry for knowledge advance using Knowledge Forum (KF) while studying a unit on electricity; they also reflected on the epistemic nature of their discourse. A comparison class of 22 students, taught by the same teacher, studied the same unit using the school’s established scientific investigation method. We hypothesised that engaging students in idea-driven and theory-building discourse, as well as scaffolding them to reflect on the epistemic nature of their discourse, would help them understand their own scientific collaborative discourse as a theory-building process, and therefore understand scientific inquiry as an idea-driven and theory-building process. As hypothesised, we found that students engaged in knowledge-building discourse and reflection outperformed comparison students in scientific epistemology and science learning, and that students’ understanding of collaborative discourse predicted their post-test scientific epistemology and science learning. To further understand the epistemic change process among knowledge-building students, we analysed their KF discourse to understand whether and how their epistemic practice had changed after epistemic reflection. The implications on ways of promoting epistemic change are discussed.  相似文献

Resistance to more humanistic forms of science education is an endemic and persistent feature of university scientists as well as school science teachers. This article argues that science education researchers should pay more attention to its origins and to the subtleties of its stubborn influence. The paper explores some of the imperatives which dominate the continuing practices of teachers; the linkages between school and university science; and re-considers the relationships between learning science, learning to do science and learning about science. It draws on recent, prominent publications, as well as neglected and rather more contentious material, to underline the unhelpfully narrow view of science held by those who defend the traditional disciplinary influences of biology, chemistry and physics. Suggestions are made as to where those of a more radical and determined disposition should direct their attention in the interests of improved education, vital scientific progress as well as human survival. It is argued that university science must change in order to ensure that teachers better help their students to learn, do and appreciate science.  相似文献

This commentary seeks to expand the dialogue on place-based science education presented in Katie Lynn Brkich’s article, where the connections fifth grade students make between their formal earth science curriculum and their lived experiences are highlighted. The disconnect between the curriculum the students are offered and their immediate environment is clear, and we are presented with examples of how they strive to make connections between the content and what they are familiar with—namely their surroundings. “Place” is identified as a term with complex meanings and interpretations, even in the scope of place-based science education, and understanding how the term is used in any given scenario is essential to understanding the implications of place-based education. Is place used as a location, locale or a sense of place? To understand “place” is to acknowledge that for the individual, it is highly situational, cultural and personal. It is just such attributes that make place-based education appealing, and potentially powerful, pedagogically on one hand, yet complex for implementation on the other. The argument is posed that place is particularly important in the context of education about the environment, which in its simplest manifestation, connects formal science curriculum to resources that are local and tangible to students. The incorporation of place in such a framework seeks to bridge the gap between formal school science subjects and students’ lived experiences, yet acknowledges the tensions that can arise between accommodating place meanings and the desire to acculturate students into the language of the scientific community. The disconnect between guiding policy frameworks and the reality of the Next Generation Science Standards is addressed opening an avenue for further discussion of the importance of socio-cultural frameworks of science learning in an ever increasing era of accountability.  相似文献

The OECD “Programme for International Student Assessment” or (PISA) is one of the largest-scale international efforts that have been launched to assess students’ scientific literacy. Such an international assessment would likely exert a profound impact on the science education policies of the participating countries/regions, including Hong Kong. This paper sets out to examine critically how scientific literacy has been assessed by PISA through analyzing its assessment frameworks and released sample items. It was found that the PISA 2000 and 2003 assessments of science have used a narrower definition of scientific literacy, as compared to that of PISA 2006 and what scientific literacy was construed for science education. However, even PISA 2006 appears to be more valid in its assessment framework, its validity was also called into question when the sample items for the trial study were examined. Knowledge about science was found largely about the processes of science, rather than the nature of science as described in the assessment framework. Besides, it intertwined with knowledge of science in a hidden manner. The application of knowledge of science in novel, real-life situations was also jeopardized because of the issue of curricular relevance. Besides these major problems, the article has discussed the problems with the concept of scientifically investigable questions and identifying research question of an investigation. Overall, the findings raised concern over what the PISA’s measure of scientific literacy actually means.  相似文献

Early science instruction is important in order to lay a firm basis for learning scientific concepts and scientific thinking. In addition, young children enjoy science. However, science plays only a minor role in the kindergarten curriculum. It has been reported that teachers feel they need to prioritize language and literacy practices over science. In this paper, we investigate whether science lessons might be integrated with learning the language functional for school: academic language. The occurrence of scientific reasoning and sophisticated vocabulary in brief science lessons with 5-year-olds is evaluated. The aim of the study was twofold: first, to explore the nature of kindergarten science discourse without any researcher directions (pre-intervention observation). Second, in a randomized control trial, we evaluated the effect on science discourse of a brief teacher training session focused on academic language awareness. The science lessons focussed on air pressure and mirror reflection. Analyses showed that teachers from the intervention group increased their use of scientific reasoning and of domain-specific academic words in their science discourse, compared to the control group. For the use of general academic words and for lexical diversity, the effect was task-specific: these dependent measures only increased during the air pressure task. Implications of the study include the need to increase teachers' awareness of possibilities to combine early science instruction and academic language learning.  相似文献

本文从维果茨基的社会文化理论的视角探讨外语教师的语言知识的建构,认为外语教师的语言知识,不论是关于语言的知识、运用语言的知识,还是教学的语言知识都应被视为是从社会环境的经验中产生的。外语教师的教学的语言知识至少应该涉及关于语言的知识,对外语学习过程的理解,以及批判的语言意识等几个方面。这几个方面的知识都与教师原有的生活经历和知识基础相关。外语教师的学习和教学经验决定了其教学的语言知识基础,这就意味着教师的自传应置于外语教师发展中的重要的地位。  相似文献

Abstract

Experiential learning theory states that reflection is just as important to learning as action. However, business educators often overlook reflection in their experiential learning activities, especially when it’s understood as a dialogue process. Drawing on reflective learning theory, we explored the case of an undergraduate business programme that has been combining experiential learning with three different reflective learning mechanisms for the past ten years. Results show that: (1) reflective dialogue is central for ensuring that impressions from experience translate into better-defined learning outcomes, (2) this dialogue process greatly benefits from a closely guided process, and (3) different reflection mechanisms contribute differently to the learning process. Considering how fast experiential learning has popularised in business schools, this study alerts educators to the importance of combining their experiential learning activities with a guided process of reflection. Otherwise, educators risk students extracting meagre, wrong or misleading impressions from their experience.  相似文献

Teaching has been described as an emerging community of practice. Within such professional communities, the processes of reflection and collaborative dialogue, or critical transformative dialogue, are central to the maintenance and improvement of professional practice for individuals, and the field. This paper reports on the challenges experienced by a group of first-year pre-service teachers engaging in a process of reflection and critique with peers, as they participated in a program focused on the development of core practices of teaching. These pre-service teachers' responses indicated their growing understanding of the importance of engaging in ongoing critical dialogue, as part of the “unnatural” aspects of teaching. The paper concludes with a reflection on the value of feedback from the earliest stages of professional learning.  相似文献

ABSTRACT

Just as language reflects one’s thoughts, the text of science textbooks reflects the structure of scientific knowledge and thought. Therefore, students’ learning of scientific language leads to their acquisition of the structure of scientific knowledge and thought. The purposes of this study were to extract scientific semantic network from science textbooks as the ideal model of using scientific language, and to examine how well science teachers are implementing scientific semantic networks in science classes by comparing and analysing their spoken language. Through a recursive method, science textbooks were searched for keywords and their relationships, and consequently a scientific semantic network was presented. As a result of the comparison with science teachers’ spoken language, it was found that the teachers were not able to implement the scientific semantic network exactly and efficiently in class, and the focus of the contents of their instruction was also different from the textbook. Science textbook was focused on qualitative aspects of the concept such as meaning, element, characteristic etc, on the other hand science teachers’ language was focused on quantitative aspect of the concept such as calculation, graph etc.  相似文献

Changes in the cultural and linguistic environments of learners are often associated with identity shifts. The aim of this study was to explore what identity shifts occur when science students from Bahraini national schools transition to an international university. The role of two aspects of learner identity—that is, English proficiency and science background knowledge, was examined in this study. Focus groups and semi-structured interviews were conducted with students and with university lecturers. The analysis suggested three conceptual themes of (1) reliance on science knowledge, (2) the auxiliary role of professional language and (3) adequacy of student learning strategies, demonstrating what subjective meanings the participants ascribe to the interplay between science knowledge and linguistic ability. The findings suggest that despite the lack of adequate linguistic attributes, the students are still able to successfully learn science in the context of language change. It is also implied that through strategically utilising their academic background in science, students preserve their identity as successful learners from school through to university. We conclude that agency plays a separate role in transition and is not a sole function of identity. We also contest the idea of language as a necessary attribute of one’s identity as it was perceived by our participants to be an advantage and an auxiliary tool rather than a requirement.  相似文献

This article investigates the introduction of a systemic curriculum change, the Essential Learnings curriculum framework, in the Australian state of Tasmania. Using Gee's [(2003). Language in the science classroom: Academic social languages as the heart of school-based literacy. In: R. Yerrick, & W.-M. Roth (Eds.), Establishing scientific classroom discourse communities: Multiple voices of teaching and learning research (pp. 19–37). Mahwah, NJ: L. Erlbaum Associates] six claims regarding the importance of language in science education, the responses of the science teachers within a secondary school to the curriculum reform were investigated. This research utilised a narrative methodology to elucidate the processes by which science teachers attempted to negotiate a sense of meaning for the reforms within their work context. Three particular challenges are highlighted for curriculum reformers. These challenges involve the potential for a linguistic distance between teachers and reformers, understanding the importance of the work context in teacher learning and the dangers of a superficial application of reform language to teacher practices. The article concludes by emphasising that the negotiation of a situated language can provide both teachers and reformers with both coherence and a common ownership of a reform, thus strengthening the potential for its implementation and institutionalisation.  相似文献

The article is a partial result of a wider research project, in which the commodification of science is interpreted, from one point of view, as a facet of the rise of neoliberalism, and from another, as a set of processes, classified according to a three-category taxonomy. Only one of the taxonomy’s categories is dealt with in this article, the one that concerns the processes that affect the programme of scientific research. First a sketch is presented of the historical background and the periodization of the most relevant epoch for the study of the commodification of science, namely, the one from the end of World War II to the present. The periodization is expressed in the notions of Golden Years science and neoliberal science. The ensuing sections have the aims: to show that, in Golden Years science, the processes shaping research programmes did not include commodification; to characterize the period of transition of the 70 s; to describe the processes of commodification that have impact on the research programmes of neoliberal science; to discuss criticisms that have been levelled against them, as well as proposals for better ways of conducting scientific practices, and their implications for science education (which are of the same nature as that of Science & Education’s editorial line); and finally, to bring to light the differences between developed and emerging countries as far as the commodification of science is concerned.  相似文献

Abstract

Photovoice, a Participatory Action Research method developed by Wang and Burris, has gained popularity as a pedagogical tool to engage youth with environmental, sustainability, and conservation issues. Influenced by Paulo Freire’s critical pedagogy, feminist theory, and documentary photography, photovoice supports reflection about place, critical dialogue about community issues, and social change by reaching policymakers. Some scholars have modified the method and applied varying frameworks to increase relevance for diverse participants. However, adaptation also may lose the original tenets. Through a scoping review, this study examined methodological applications to science, conservation, and sustainability education and whether emerging approaches align with Wang and Burris’ original goals. The scoping review identified and analyzed four applications of photovoice: i) place as pedagogy, ii) conservation and sustainability, iii) STEM teaching; and iv) decolonizing education. Current scholarship shows promise for photovoice in environmental education applications to support participatory, diverse, and equitable educational settings, but some projects would benefit from more explicit attention to the original emancipatory intents of the method.  相似文献

The work of science is a linguistic act. However, like history and philosophy of science, language has frequently been isolated from science content due to factors such as school departmentalization and narrow definitions of what it means to teach, know, and do science. This conceptual article seeks to recognize and recognize—to understand and yet rethink—science content in light of the vision of science expected by academic standards. Achieving that vision requires new perspectives in science teaching and teacher education that look into the role that science language expectations play in science content. These perspectives reposition attention to language from a hidden, overlooked, or outsourced aspect of science teaching, to one at its core. To help bring teachers and teacher educators into this integrative view of science content, this article offers a mirror, a prism, and a lens as three metaphorical tools to explore the essential roles that language plays for, in, and as science content. The reflection, refraction, and refocusing of science content reveal complex science language expectations that function alongside facts, figures, and formulas of science as gatekeeping mechanisms that, once noticed, cannot be ignored or marginalized in science teaching and science teacher education.  相似文献
