In this study, we examine how bilingual students in elementary school use their languages and what this means for their meaning-making in science. The class was multilingual with students bilingual in different minority languages and the teacher monolingual in Swedish. The analysis is based on a pragmatic approach and the theory of translanguaging. The science content was electricity, and the teaching involved class instruction and hands-on activities in small groups. The findings of the study are divided into two categories, students’ conversations with the teacher and student’s conversations with each other. Since the class was multilingual, the class instruction was carried out in Swedish. Generally, when the conversations were characterised by an initiation, response and evaluation pattern, the students made meaning of the activities without any language limitations. However, when the students, during whole class instruction, were engaged in conversations where they had to argue, discuss and explain their ideas, their language repertoire in Swedish limited their possibilities to express themselves. During hands-on activities, students with the same minority language worked together and used both of their languages as resources. In some situations, the activities proceeded without any visible language limitations. In other situations, students’ language repertoire limited their possibilities to make meaning of the activities despite being able to use both their languages. What the results mean for designing and conducting science lessons in a multilingual class is discussed. 相似文献

Building on a pedagogical model designed to support the teaching and learning of the language of science investigation practices with middle school emergent bilingual learners, we developed a series of soccer and science investigations to promote interest and engagement in science learning. We used assemblage theory to study how students engaged in and acted within this bilingual curriculum situated in an afterschool soccer practice context. We found that soccer, a passion for several Latino students, can be used as a cultural tool for science teachers to support the emerging bilingual students’ learning process. Implications for educators and researchers considering ways of integrating diverse students’ cultural practices and passions with culturally sustaining pedagogies for science teaching and learning are discussed. 相似文献

The dominant role of English as the global language of science entails a requirement for science teachers to equip their non-native English-speaking students with receptive and productive language skills for communication in scientific contexts. Although science courses with English elements are part of some schools’ bilingual programmes, they are usually not available to a wider student audience, but are restricted to high achieving or highly motivated students. The present study was to test whether a newly developed biology content and language integrated learning (CLIL) unit could also benefit standard ninth grade classes. The learning gains and motivation of bilingually inexperienced students were compared to those of a preselected group and a comparison group that had been taught solely in their native language. All participating classes achieved similar gains in content knowledge, and the standard students rated their motivation for bilingual science lessons as positive, albeit not as high as the preselected group. We thus provide evidence against concerns that teaching non-selected students bilingually might lead to deficits in content knowledge acquisition. Following this, we conclude that scientific English should be a part of standard science lessons regardless of specific school programmes. 相似文献

Although the importance of language in science learning has been widely recognized by researchers, there is limited research on how science teachers perceive the roles that language plays in science classrooms. As part of an intervention design project that aimed to enhance teachers’ capacity to address the language demands of science, interview data (N = 9) were collected to understand teachers’ perceptions and experiences with a wide range of issues related to language use in science classrooms. Adopting an interpretive approach to qualitative data, the analysis revealed that the teachers perceive a wide range of student difficulties related to language use in science classrooms, especially to the use of specialized terms and writing. Although the teachers are keenly aware of how language can be a barrier to learning science, they are less certain as to what students need to know about the language of science in order to master it. The findings suggested professional support that highlights the distinctive language demands of science and how these demands differ from other subject areas could be useful to these elementary school teachers. 相似文献

The intent of national efforts to frame science education standards is to promote students’ development of scientific practices and conceptual understanding for their future role as scientifically literate citizens (NRC 2012). A guiding principle of science education reform is that all students receive equitable opportunities to engage in rigorous science learning. Yet, implementation of science education reform depends on teachers’ instructional decisions. In urban schools serving students primarily from poor, diverse communities, teachers typically face obstacles in providing reform-based science due to limited resources and accountability pressures, as well as a culture of teacher-directed pedagogy, and deficit views of students. The purpose of this qualitative research was to study two white, fourth grade teachers from high-poverty urban schools, who were identified as transforming their science teaching and to investigate how their beliefs, knowledge bases, and resources shaped their planning for reform-based science. Using the Shavelson and Stern’s decision model for teacher planning to analyze evidence gathered from interviews, documents, planning meetings, and lesson observations, the findings indicated their planning for scientific practices was influenced by the type and extent of professional development each received, each teacher’s beliefs about their students and their background, and the mission and learning environment each teacher envisioned for the reform to serve their students. The results provided specific insights into factors that impacted their planning in high-poverty urban schools and indicated considerations for those in similar contexts to promote teachers’ planning for equitable science learning opportunities by all students. 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

Conventional assessment analysis of student results, referred to as rubric-based assessments (RBA), has emphasized numeric scores as the primary way of communicating information to teachers about their students’ learning. In this light, rethinking and reflecting on not only how scores are generated but also what analyses are done with them to inform classroom practices is of utmost importance. Informed by Systemic Functional Linguistics and Latent Dirichlet Allocation analyses, this study utilizes an innovative bilingual (Spanish–English) constructed response assessment of science and language practices for middle and high school students to perform a multilayered analysis of student responses. We explore multiple ways of looking at students’ performance through their written assessments and discuss features of student responses that are made visible through these analyses. Findings from this study suggest that science educators would benefit from a multidimensional model which deploys complementary ways in which we can interpret student performance. This understanding leads us to think that researchers and developers in the field of assessment need to promote approaches that analyze student science performance as a multilayered phenomenon. 相似文献

Grounded in Hallidayan perspectives on academic language, we report on our development of an educative science assessment as one component of the language-rich inquiry science for English-language learners teacher professional learning project for middle school science teachers. The project emphasizes the role of content-area writing to support teachers in diagnosing their students’ emergent understandings of science inquiry practices, science content knowledge, and the academic language of science, with a particular focus on the needs of English-language learners. In our current school policy context, writing for meaningful purposes has received decreased attention as teachers struggle to cover large numbers of discrete content standards. Additionally, high-stakes assessments presented in multiple-choice format have become the definitive measure of student science learning, further de-emphasizing the value of academic writing for developing and expressing understanding. To counter these trends, we examine the implementation of educative assessment materials—writing-rich assessments designed to support teachers’ instructional decision making. We report on the qualities of our educative assessment that supported teachers in diagnosing their students’ emergent understandings, and how teacher–researcher collaborative scoring sessions and interpretation of assessment results led to changes in teachers’ instructional decision making to better support students in expressing their scientific understandings. We conclude with implications of this work for theory, research, and practice. 相似文献

ABSTRACTJust 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

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

This qualitative video study explores how two elementary school teachers taught for conceptual understanding throughout different phases of science inquiry. The teachers implemented teaching materials with a focus on learning science key concepts through the development of word knowledge. A framework for word knowledge was applied to examine the students’ level of word knowledge manifested in their talk. In this framework, highly developed knowledge of a word is conceptual knowledge. This includes understanding how the word is situated within a network of other words and ideas. The results suggest that students’ level of word knowledge develops toward conceptual knowledge when the students are required to apply the key concepts in their talk throughout all phases of inquiry. When the students become familiar with the key concepts through the initial inquiry activities, the students use the concepts as tools for furthering their conceptual understanding when they discuss their ideas and findings. However, conceptual understanding is not promoted when teachers do the talking for the students, rephrasing their responses into the correct answer or neglecting to address the students’ everyday perceptions of scientific phenomena. 相似文献

In this paper we reflect on the article, Science education in a bilingual class: problematising a translational practice, by Zeynep Ünsal, Britt Jakobson, Bengt-Olav Molander and Per-Olaf Wickman (Cult Stud Sci Educ, doi: 10.1007/s11422-016-9747-3). In their article, the authors present the results of a classroom research project by responding to one main question: How is continuity between everyday language and the language of science construed in a bilingual science classroom where the teacher and the students do not speak the same minority language? Specifically, Ünsal et al. examine how bilingual students construe relations between everyday language and the language of science in a class taught in Swedish, in which all students also spoke Turkish, whereas the teacher also spoke Bosnian, both being minority languages in the context of Swedish schools. In this forum, we briefly discuss why close attention to bilingual dynamics emerging in classrooms such as those highlighted by Ünsal et al. matters for science education. We continue by discussing changing ontologies in relation to linguistic diversity and education more generally. Recent research in bilingual immersion classroom settings in so-called “content” subjects such as Content and Language Integrated Learning, is then introduced, as we believe this research offers some significant insights in terms of how bilingualism contributes to knowledge building in subjects such as science. Finally, we offer some reflections in relation to the classroom interactional competence needed by teachers in linguistically diverse classrooms. In this way, we aim to further the discussion initiated by Ünsal et al. and to offer possible frameworks for future research on bilingualism in science education. In their article, Ünsal et al. conclude the analysis of the classroom data by arguing in favor of a translanguaging pedagogy, an approach to teaching and learning in which students’ whole language repertoires are used as valuable resources for constructing meaning and for developing academic competences in the language of instruction. This is a conclusion that we support wholeheartedly and an educational practice that we hope to promote with this forum discussion. 相似文献

This study examines the impact of Disaggregate Instruction on students’ science learning. Disaggregate Instruction is the idea that science teaching and learning can be separated into conceptual and discursive components. Using randomly assigned experimental and control groups, 49 fifth‐grade students received web‐based science lessons on photosynthesis using our experimental approach. We supplemented quantitative statistical comparisons of students’ performance on pre‐ and post‐test questions (multiple choice and short answer) with a qualitative analysis of students’ post‐test interviews. The results revealed that students in the experimental group outscored their control group counterparts across all measures. In addition, students taught using the experimental method demonstrated an improved ability to write using scientific language as well as an improved ability to provide oral explanations using scientific language. This study has important implications for how science educators can prepare teachers to teach diverse student populations. 相似文献

For many years I have engaged future mathematics teachers in activities that focus on emotional dimensions of their learning. Even those teachers who were able to reconstruct themselves as learners of mathematics had difficulties with changing their practice. Through a series of autobiographical stories, I examine my own experiences as a teacher and a learner. These stories—one from a computer class, one from a workshop for elementary teachers, one from college, and one from eighth grade—serve as data from which I draw themes that capture the tensions that I experience as I teach. Sharing these tensions with mathematics teachers has had an impact on the way the teachers talk about their teaching and promises to change how they teach. The paper is written to encourage teacher educators to adopt the practice of sharing teaching and learning stories with their students. 相似文献

学习任何一门语言的最终目的都是为了能够运用其进行交流。所以口头表达能力是语言学习中相当重要的一个环节。在课堂的教学中,激励学生开口运用所学语言表达自己的想法是语言教学的首要任务。外语教师必须通过课堂内外的技能训练来开发学生的口语技能,为学生们以后的语言运用打好扎实的基础。 相似文献

During the last decade there has been on-going discussions about students’ declining interest and low achievement in science. One of the reasons suggested for this decline is that teachers and students have different frames of reference, whereby teachers sometimes communicate science in the classroom in a way that is not accessible to the students. There is a lack of research investigating the effects of coteaching with senior students in science in upper secondary schools. To improve teaching and to narrow the gap between teachers’ and students’ different frames of references, this study investigates how an experienced chemistry teacher gains and refines her pedagogical content knowledge (PCK) by cooperating with two grade 12 students (age 18) as coteachers. The teacher and the two coteachers coplanned, cotaught and coevaluated lessons in chemical bonding in a grade 10 upper secondary class. Findings indicate that the coteachers contributed with their own learning experiences to help the teacher understand how students perceive difficult concepts. In such way, the coteachers were mediating between the teacher and the students, thus bridging the gap between the teacher and the students’ frames of references. The teachers’ PCK was refined which in turn lead to improved teaching strategies. 相似文献

This article presents findings from a 9–month ethnographic study of cross–cultural learning for the purpose of helping teachers better understand classroom conditions and behaviors that support and hinder students’ comprehension of teachers’ spoken language. Data from a close, observational study of an 8–year–old learning to get along in a new language environment illustrate conditions that caused her to tune out and those that supported her attempts to comprehend. Because spoken language often sounds like an incomprehensible string of sounds to a new language learner, this article suggests that incomprehensibility as well as students’ discomfort and sense of vulnerability can be greatly reduced when teachers scaffold their use of language in specific ways. 相似文献
