In this review, we explore the notion of teaching science to English language learners (ELLs) as a balancing act between simultaneously focusing on language and content development, on the one hand, and between structuring instruction and focusing on student learning processes, on the other hand. This exploration is conducted through the lens of a theoretical framework embedded in the Science Writing Heuristic approach, an approach exemplifying immersive orientation to argument-based inquiry. Three learning processes (learning through the language of science, learning about the language of science and living the language of science) and three classroom structures (collective zone of proximal development, symmetric power and trust relationships and teacher as decision-maker) are explored in relation to learning theories and empirical findings from second language acquisition and science, multicultural and teacher education bodies of work. Three themes – negotiation, embeddedness and non-threatening learning environments – to inform ELL science education emerged from the review.  相似文献

The purpose of this article is to describe the current state of knowledge and practice in the flipped learning approach in engineering education and to provide guidance for practitioners by critically appraising and summarizing existing research. This article is a qualitative synthesis of quantitative and qualitative research investigating the flipped learning approach in engineering education. Systematic review was adopted as the research methodology and article selection and screening process are described. Articles published between 2000 and May 2015 were reviewed, and 62 articles were included for a detailed analysis and synthesis. The results indicated that flipped learning gained popularity amongst engineering educators after 2012. The review revealed that research in engineering education focused on documenting the design and development process and sharing preliminary findings and student feedback. Future research examining different facets of a flipped learning implementation, framed around sound theoretical frameworks and evaluation methods, is still needed to establish the pedagogy of flipped learning in teaching engineering.  相似文献

This review, written to celebrate the 25th anniversary of the International Journal of Science Education, revealed a period of changes in the theoretical views of the language arts, the perceived roles of language in science education, and the research approaches used to investigate oral and written language in science, science teaching, and learning. The early years were dominated by behavioralist and logico-mathematical interpretations of human learning and by reductionist research approaches, while the later years reflected an applied cognitive science and constructivist interpretations of learning and a wider array of research approaches that recognizes the holistic nature of teaching and learning. The early years focus on coding oral language into categories reflecting source of speech, functional purpose, level of question and response, reading research focused on the readability of textbooks using formulae and the reader's decoding skills, and writing research was not well documented since the advocates for writing in service of learning were grass roots practitioners and many science teachers were using writing as an evaluation technique. The advent of applied cognitive science and the constructivist perspectives ushered in interactive-constructive models of discourse, reading and writing that more clearly revealed the role of language in science and in science teaching and learning. A review of recent research revealed that the quantity and quality of oral interactions were low and unfocused in science classrooms; reading has expanded to consider comprehension strategies, metacognition, sources other than textbooks, and the design of inquiry environments for classrooms; and writing-to-learn science has focused on sequential writing tasks requiring transformation of ideas to enhance science learning. Several promising trends and future research directions flow from the synthesis of this 25-year period of examining the literacy component of science literacy - among them are critical listening and reading of various sources, multi-media presentations and representations, effective debate and argument, quality explanation and the role of information and communication technologies/environments.  相似文献

The traditional approach to the education of language minority students separates English language development from content instruction because it is assumed that English language proficiency is a prerequisite for subject matter learning. The authors of this article take the alternate view that the integration of inquiry science and language acquisition enhances learning in both domains. The report describes a conceptual framework for science–language integration and the development of a five‐level rubric to assess teachers' understanding of curricular integration. The science–language integration rubric describes the growth of teacher expertise as a continuum from a view of science and language as discreet unrelated domains to the recognition of the superordinate processes that create a synergistic relationship between inquiry science and language development. Examples from teacher interviews are used to illustrate teacher thinking at each level. © 2002 Wiley Periodicals, Inc. J Res Sci Teach 39: 664–687, 2002  相似文献

This paper examines the use and role of the term ‘hypothesis’ in science teacher education as described by teacher students. Data were collected through focus group interviews conducted at seven occasions with 32 students from six well‐known Swedish universities. The theoretical framework is a sociocultural and pragmatist perspective on language and learning, introducing the notion of pivot terms to operationalise language use as a habit and mediated action. We describe three different customs of using the term ‘hypothesis’ within four cultural institutions that can be said to constitute science teacher education in Sweden. Students were found to habitually use the term hypothesis as meaning a guess about an outcome. This is contrasted to the function of this term in scientific research as a tentative explanation. We also found differences in how this term was used between the pure science courses given by the science departments of universities and science education courses taken only by teacher students. Findings also included further support for school students hypothesis fear reported in an earlier study. It is discussed how these findings can obstruct learning and teaching about the nature of scientific inquiry. Constructivist theories of learning are suggested as a possible origin of these problems. The findings are also related to curricular reform and development.  相似文献

In science education, students should come to understand the nature and significance of models. In the case of chemistry education it is argued that the present use of models is often not meaningful from the students' perspective. A strategy to overcome this problem is to use an authentic chemical modelling practice as a context for a curriculum unit. The theoretical framework for this strategy is activity theory rooted in socio‐cultural theories on learning. An authentic chemical modelling practice is characterized by a set of motives for model development through a well‐defined modelling procedure using only relevant issue knowledge. The aim of this study was to explore, analyse, and select authentic chemical modelling practices for use in chemistry education. The suitability of the practices was reviewed by applying a stepwise procedure focused on criteria such as students' interest and ownership, modelling procedure, issue knowledge, and feasibility of the laboratory work in the classroom. It was concluded that modelling drinking‐water treatment and human exposure assessment are both suitable to serve as contexts, because both practices exhibit clear motives for model construction and the applied modelling procedures are in line with students' pre‐existing procedural modelling knowledge. The issue knowledge involved is consistent with present Dutch science curriculum, and it is possible to carry out experimental work in the classroom for model calibration and validation. The method described here to select and evaluate practices for use as contexts in chemistry education can also be used in other science domains.  相似文献

Science educators have suggested that, for minority and low-income students, gaps between home and school science cultures necessitate ‘border crossing’ for successful learning in science. Our analysis used National Assessment of Educational Progress 2000 and 2005 data to assess the impact of U.S. state-level policy regarding instructional models for language acquisition for the learning of science. Specifically, we assessed whether policy favouring structured English immersion led to better student outcomes than bilingual education among Hispanic English language learners in 4th and 8th grades in the U.S. We found significantly higher science achievement among 4th grade Hispanic ELLs in states with stronger bilingual emphasis in their policy, suggesting that policy support for bilingual education could provide a better bridge to span the cultural gap between home and school science, at least for younger students.  相似文献

This qualitative case study looks closely at an elementary teacher who participated in professional development experiences that helped her develop a hybrid practice of using inquiry-based science to teach both science content and English language development (ELD) to her students, many of whom are English language learners (ELLs). This case study examines the teacher’s reflections on her teaching and her students’ learning as she engaged her students in science learning and supported their developing language skills. It explicates the professional learning experiences that supported the development of this hybrid practice. Closely examining the pedagogical practice and reflections of a teacher who is developing an inquiry-based approach to both science learning and language development can provide insights into how teachers come to integrate their professional development experiences with their classroom expertise in order to create a hybrid inquiry-based science ELD practice. This qualitative case study contributes to the emerging scholarship on the development of teacher practice of inquiry-based science instruction as a vehicle for both science instruction and ELD for ELLs. This study demonstrates how an effective teaching practice that supports both the science and language learning of students can develop from ongoing professional learning experiences that are grounded in current perspectives about language development and that immerse teachers in an inquiry-based approach to learning and instruction. Additionally, this case study also underscores the important role that professional learning opportunities can play in supporting teachers in developing a deeper understanding of the affordances that inquiry-based science can provide for language development.  相似文献

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

Visualizations are an increasingly important part of scientific education and discovery. However, users often do not gain knowledge from them in a complete or efficient way. This article aims to direct research on visualizations in science education in productive directions by reviewing the evidence for widespread assumptions that learning styles, sex differences, developmental stages, and spatial language determine the impact of visualizations on science learning. First, we examine the assumption that people differ in their verbal versus visual learning style. Due to the lack of rigorous evaluation, there is no current support for this distinction. Future research should distinguish between two different kinds of visual learning style. Second, we consider the belief that there are large and intractable sex differences in spatial ability resultant from immutable biological reasons. Although there are some spatial sex differences (in some types of spatial tests although not all), there is actually only very mixed support for biological causation. Most important, there is conclusive evidence that spatial skills can be improved through training and education. Third, we explore educators' use of Piaget's ideas about spatial development to draw conclusions about ‘developmental appropriateness’. However, recent research on spatial development has focused on identifying sequences that begin with early starting points of skill, and spatial education is possible in some form at all ages. Fourth, although spatial language does not determine spatial thought, it does frame attention in a way that can have impact on learning and understanding. We examine the empirical support for each assumption and its relevance to future research on visualizations in science education.  相似文献

The challenge of preparing novice primary teachers for teaching in an educational environment, where science education has low status and many teachers have limited science content knowledge and lack the confidence to teach science, is great. This paper reports on an innovation involving a sustained simulation in an undergraduate science education course as a mediational tool to connect two communities of practice—initial teacher education and expert primary science teaching. The course lecturer and student teachers role-played the expert classroom teacher and primary students (Years 7/8) respectively in an attempt to gain insights into teaching and learning through authentic activity that models good practice in primary science teaching and learning. Activity theory was used to help frame and analyse the data. Findings from the first trial indicate that the simulation was very effective in initiating science pedagogical content knowledge (PCK) development of primary student teachers.  相似文献

To a science ‘outsider’, science language often appears unnecessarily technical and dense. However, scientific language is typically used with the goal of being concise and precise, which allows those who regularly participate in scientific discourse communities to learn from each other and build upon existing scientific knowledge. One essential component of science language is the academic vocabulary that characterises it. This mixed-methods study investigates middle school students’ (N?=?59) growth in academic vocabulary as it relates to their teacher’s instructional practices that supported academic language development. Students made significant gains in their production of general academic words, t(57)?=?2.32, p?=?.024 and of discipline-specific science words, t(57)?=?3.01, p?=?.004 in science writing. Results from the qualitative strand of this inquiry contextualised the students’ learning of academic vocabulary as it relates to their teacher’s instructional practices and intentions as well as the students’ perceptions of their learning environment. These qualitative findings reveal that both the students and their teacher articulated that the teacher’s intentional use of resources supported students’ academic vocabulary growth. Implications for research and instruction with science language are shared.  相似文献

The case for a greater role for the history and philosophy of science in science education is reviewed. It is argued that such a role can only be realised if it is based on both a credible analytical approach to the history and philosophy of science and if the evolution of a sufficient number of major themes in science is known in suitable detail. Adopting Lakatos' Theory of Scientific Research Programmes as the analytical approach, it is proposed that the development, use, and replacement, of specific models forms the core of such programmes.Chemical kinetics was selected as an exemplar major topic in chemistry. Eight models which have played a central role in the evolution of the study of chemical kinetics were identified by an analysis of the literature. The implications that these models have for the teaching and learning of chemistry today are discussed.  相似文献

With the globalisation of education, large numbers of students with interrupted schooling and low English literacy levels represent both a quantitative and qualitative shift in the kinds of students faced by teachers in classrooms. In Australia, after a year in an intensive English language programme, immigrant and refugee students are placed in the mainstream, where they face enormous challenges in content areas such as science. The complexity and specificity of science terminology pose a serious barrier for students. This article reports on a research project to support vocabulary learning in mainstream science for Year 8 refugee students (n = 23) in one high school. Data sources included teacher interviews, student journal writing, and the science text itself. The author demonstrates why science content language is inaccessible to many students through an extensive review of the literature, and then juxtaposes the views of students and teachers with the actual demands of one chapter from the Year 8 Science textbook on states of matter. The final section presents the response of the researchers to help scaffold vocabulary learning for this topic and a trial of the materials. The study highlights the links between conceptual and linguistic understanding. Given that students identified vocabulary as a major barrier to learning, and that the science teacher tended to assume rather than to explain new terminology, the language‐focused approach outlined to support vocabulary was seen as one way to address an urgent problem. Implications for professional development and teacher education are also addressed.  相似文献

STEM education faces an interesting conundrum. Western countries have implemented constructivist inspired student centred practices which are argued to be more engaging and relevant to student learning than the traditional, didactic approaches. However, student interest in pursuing careers in STEM have fallen or stagnated. In contrast, students in many developing countries in which teaching is still somewhat didactic and teacher centred are more disposed to STEM related careers than their western counterparts. Clearly factors are at work which impact the way students value science and mathematics. This review draws on three components that act as determinants of science education in three different countries – Australia, India and Malaysia. We explore how national priorities and educational philosophy impacts educational practices as well as teacher beliefs and the need for suitable professional development. Socio-economic conditions for science education that are fundamental for developing countries in adopting constructivist educational models are analysed. It is identified that in order to reduce structural dissimilarities among countries that cause fragmentation of scientific knowledge, for Malaysia constructivist science education through English medium without losing the spirit of Malaysian culture and Malay language is essential while India need to adopt constructivist quality indicators in education. While adopting international English education, and reducing dominance of impact evaluation, India and Malaysia need to prevent losing their cultural and social capital vigour. Furthermore the paper argues that Australia might need to question the efficacy of current models that fail to engage students’ long term interest in STEM related careers. Australian and Malaysian science teachers must be capable of changing the personal biographies of learners for developing scientific conceptual information. In addition both Malaysia and Australia need to provide opportunities for access to different curricular programmes of knowledge based constructivist learning for different levels of learner competencies.  相似文献

In this paper, the role of modelling in the teaching and learning of science is reviewed. In order to represent what is entailed in modelling, a 'model of modelling' framework is proposed. Five phases in moving towards a full capability in modelling are established by a review of the literature: learning models; learning to use models; learning how to revise models; learning to reconstruct models; learning to construct models de novo . In order to identify the knowledge and skills that science teachers think are needed to produce a model successfully, a semi-structured interview study was conducted with 39 Brazilian serving science teachers: 10 teaching at the 'fundamental' level (6-14 years); 10 teaching at the 'medium'-level (15-17 years); 10 undergraduate pre-service 'medium'-level teachers; 9 university teachers of chemistry. Their responses are used to establish what is entailed in implementing the 'model of modelling' framework. The implications for students, teachers, and for teacher education, of moving through the five phases of capability, are discussed.  相似文献

Science literacy for all is the central goal of science education reforms, and there is a growing importance of the language arts in science. Furthermore, there are strong calls for teacher professionalism and self-directed professional learning that involve evidence-based best practices. This raises questions about whether science teaching journals?? recommendations are anchored to high-quality evidence. We found that (a) most National Science Teacher Association journals?? science literacy recommendations have weak or no evidence base and (b) those with evidence reference teaching journals, teacher resource books, and literacy education more often than science education research. We concluded that all participants in the knowledge production cycle and transfer process??authors, editors, and reviewers??need to encourage evidence-based practices anchored to ongoing reforms and to literacy and science education research.  相似文献
