This qualitative sociolinguistic research study examines Latino/a students’ use of language in a science classroom and laboratory. This study was conducted in a school in the southwestern United States that serves an economically depressed, predominantly Latino population. The object of study was a 5th-grade bilingual (Spanish/English) class. The findings demonstrate the students’ awareness of their own bilingualism, their preference for speaking Spanish, and their conceptualization of English as the language of academic success. Most significantly, this study reveals how the institutional context impacts both the teacher’s and the students’ behaviors, resulting in an implicit institutionalized bias against Spanish.  相似文献

Bilingual and multilingual speakers mix two or more languages for communication, gaining information and sense-making in varieties of contexts. How do bilinguals mix languages and what does the mixing afford for their learning and participation? This study examines these questions, focusing on Korean-English bilingual youths in a community-based after-school science programme in the United States. A close analysis of videorecordings of the programme sessions demonstrates the ways in which bilinguals negotiate their participant positions and negotiate meanings in their study of science topics. The findings reveal that bilinguals utilise their Korean proficiency to craft diverse ways of participation and that linguistic and scientific sense-making co-occur and support each other. Based on these findings, I offer implications as to how science teachers should perceive students’ mixing of multiple languages and how they can support bilinguals’ learning of science content and English. Additionally, I suggest a future research direction that can help teachers to prepare for linguistically diverse science-learning and -teaching contexts.  相似文献

This article examines an ESL English language arts teacher’s conceptions of linguistic diversity, literacy learning and her role as teacher in a culturally and linguistically complex classroom. It further examines her processes of learning about, and developing curricular and pedagogical innovations to meet, her students’ learning needs. The successes and paradoxes of, as well as constraints to, those efforts are explored. The paper uses Ball’s theory of generativity and recent research on effective English language arts instruction in culturally and linguistically complex classrooms to facilitate analysis. It offers some implications for teachers’ development of generativity for teaching culturally and linguistically diverse 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

Recent science-education reforms have targeted students’ ability to ‘talk science’, especially in science classrooms. Prior research has shown that participation in scientific discourse in class is one of the most challenging scientific-literacy tasks, and particularly complex for English language learners (ELLs) at the upper elementary level. The present study explores this issue in a fourth-grade science classroom in the United States in which students from various linguistic and cultural backgrounds were studying together. Specifically, it analyzes the case of a focal Asian-background ELL who encountered challenges in her attempts to respond to the teacher’s questions and participate in the classroom academic discourse on earth science. Our analysis indicated that this ELL was unaware of the teacher’s expectations regarding the intertextual connections and academic language required to successfully accomplish science tasks. The ELL’s unexpected responses exposed a complex set of academic and social issues – notably, gaps between the teacher’s, students’, and ELL’s own expectations about language participation – that could have contributed to her supposed behavioural problems.  相似文献

This year-long, quasi-experimental study investigated the impact of the use of netbook computers and interactive science software on fifth-grade students’ science learning processes, academic achievement, and interest in further science, technology, engineering, and mathematics (STEM) study within a linguistically diverse school district in California. Analysis of students’ state standardized science test scores indicated that the program helped close gaps in scientific achievement between at-risk learners (i.e., English learners, Hispanics, and free/reduced-lunch recipients) and their counterparts. Teacher and student interviews and classroom observations suggested that computer-supported visual representations and interactions supported diverse learners’ scientific understanding and inquiry and enabled more individualized and differentiated instruction. Finally, interviews revealed that the program had a positive impact on students’ motivation in science and on their interest in pursuing science-related careers. This study suggests that technology-facilitated science instruction is beneficial for improving at-risk students’ science achievement, scaffolding students’ scientific understanding, and strengthening students’ motivation to pursue STEM-related careers.  相似文献

This article shows how various dialogic discourse strategies were used in read-alouds of English science information books in a 2nd-grade bilingual classroom. Using a variety of discursive strategies, Ibett encouraged her Spanish-speaking students to provide explanations and reasoning related to science ideas. Similarly, she used intertextual connections to prior classroom discourse, prompted deep understanding of new concepts, and reinforced vocabulary. This article illustrates that it is possible to employ dialogic practices in read-alouds of English informational science texts in bilingual classrooms to strengthen both language/literacy and science instruction.  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

During 2nd language acquisition, a learner’s identity is consigned, juxtaposed, coconstructed, and reified through various affective positions and mitigating linguistic behaviors. Our study of adult Latino ESL students in Dallas, Texas, shows how language socialization experiences are shaped by the learners’ affective stances toward the project of learning and using the English language. Students reflected on how their specific social barriers created conditions that impeded interaction with interlocutors who could potentially aid their socialization process in English.  相似文献

English connects all areas of science around the world. Productive and receptive English-language skills are thus a crucial tool that schools must provide their students with in order to prepare them for higher education and professional life. The introduction of bilingual instruction of subject matter, often referred to as Content and Language Integrated Learning (CLIL), allows for incorporating English as a medium of communication directly into the science classroom. However, such bilingual lessons are often only accessible in the context of bilingual programmes for which students have to qualify based on their previous performance. The present study assessed the applicability of bilingual modules in non-selected groups of students. For this, a bilingual teaching unit on immunology was developed and implemented in standard German ninth grade classes. After the unit, bilingually taught students showed the same content knowledge gains as their peers who had been taught solely in their native language. Average achievement motivation ratings before and after the unit were medium to high in all classes, and the majority of students was open to more bilingual lessons. An evaluation of student comments provides further indications for the development of future bilingual units.  相似文献

With increasing numbers of students learning science through a second language in many school contexts, there is a need for research to focus on the impact language has on students’ understanding of science concepts. Like other countries, Brunei has adopted a bilingual system of education that incorporates two languages in imparting its curriculum. For the first three years of school, Brunei children are taught in Malay and then for the remainder of their education, instruction is in English. This research is concerned with the influence that this bilingual education system has on children’s learning of science. The purpose was to document the patterns of Brunei students’ developing understandings of the concepts of living and non-living things and examine the impact in the change in language as the medium of instruction. A cross-sectional case study design was used in one primary school. Data collection included an interview (n = 75), which consisted of forced-response and semi-structured interview questions, a categorisation task and classroom observation. Data were analysed quantitatively and qualitatively. The results indicate that the transition from Malay to English as the language of instruction from Primary 4 onwards restricted the students’ ability to express their understandings about living things, to discuss related scientific concepts and to interpret and analyse scientific questions. From a social constructivist perspective these language factors will potentially impact on the students’ cognitive development by limiting the expected growth of the students’ understandings of the concepts of living and non-living things.

In reform-based science curricula, students’ discursive participation is highly encouraged as a means of science learning as well as a goal of science education. However, Asian immigrant students are perceived to be quiet and passive in classroom discursive situations, and this reticence implies that they may face challenges in discourse-rich science classroom learning environments. Given this potentially conflicting situation, the present study aims to understand how and why Asian immigrant students participate in science classroom discourse. Findings from interviews with seven Korean immigrant adolescents illustrate that they are indeed hesitant to speak up in classrooms. Drawing upon cultural historical perspectives on identity and agency, this study shows how immigrant experiences shaped the participants’ othered identity and influenced their science classroom participation, as well as how they negotiated their identities and situations to participate in science classroom and peer communities. I will discuss implications of this study for science education research and science teacher education to support classroom participation of immigrant students.  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 paper describes a qualitative study that investigated the nature of the participation structures and how the participation structures were organized by four science teachers when they constructed and communicated science content in their classrooms with computer technology. Participation structures focus on the activity structures and processes in social settings like classrooms thereby providing glimpses into the complex dynamics of teacher–students interactions, configurations, and conventions during collective meaning making and knowledge creation. Data included observations, interviews, and focus group interviews. Analysis revealed that the dominant participation structure evident within participants’ instruction with computer technology was (Teacher) initiation–(Student and Teacher) response sequences–(Teacher) evaluate participation structure. Three key events characterized the how participants organized this participation structure in their classrooms: setting the stage for interactive instruction, the joint activity, and maintaining accountability. Implications include the following: (1) teacher educators need to tap into the knowledge base that underscores science teachers’ learning to teach philosophies when computer technology is used in instruction. (2) Teacher educators need to emphasize the essential idea that learning and cognition is not situated within the computer technology but within the pedagogical practices, specifically the participation structures. (3) The pedagogical practices developed with the integration or with the use of computer technology underscored by the teachers’ own knowledge of classroom contexts and curriculum needs to be the focus for how students learn science content with computer technology instead of just focusing on how computer technology solely supports students learning of science content.  相似文献

Social work programs that prepare students for culturally competent practice rely on the principle that cultural identity and differences are positive; and that social work services need to be delivered in ways which are culturally acceptable to clients and enhance their ethnic group participation and power. Cross-cultural experiences facilitate the development of cultural competence. Equipping students in the necessary affective, cognitive, and behavioral areas for cross-cultural learning and competent practice call for teaching approaches that capitalize on the adult learning process; and where meaningful learning can be transformed to a learning process beyond the academic experience. This paper presents a cross-cultural teaching model designed to facilitate a culturally transformative learning process within the classroom and with the Hartford Latino Community in Connecticut.  相似文献

Formative assessment, bilingualism, and argumentation when combined can enrich bilingual scientific literacy. However, argumentation receives little attention in the practice of bilingual science education. This article describes the effect of a formative assessment-based pedagogical strategy in promoting university students’ argumentation. It examines the written and oral arguments produced by 54 undergraduates (28 females and 26 males, 16–21 years old) in Colombia during a university bilingual (Spanish-English) science course. The data used in this analysis was derived from students’ written responses, and audio and video recordings. The first goal of this study was to determine how this teaching strategy could help students increase the use of English as a means of communication in argumentation in science. The second goal was to establish the potential of the strategy to engage students in argumentative classroom interactions as an essential part of formative assessment. The findings show that the strategy provided participants with opportunities to write their argumentation in Spanish, in English and in a hybrid version using code-switching. Educational implications for higher education are discussed.  相似文献

Scientific inquiry activities are considered as productive science instruction to improve students’ science learning and achievement. Supportive teacher-student relationships and positive disciplinary climate in the classroom are also two important factors that could facilitate student learning. This study investigates whether the association between the inquiry-based science activities and student science achievement varies by teacher support and disciplinary climate in science classrooms, particularly when taking into consideration of student gender difference and socioeconomic status (SES). This study performed regression analyses using Beijing, Shanghai, Jiangsu, and Guangdong (B-S-J-G-China) students’ science performance and background survey data of 2015 Program for International Student Assessment (PISA). Results showed that disciplinary climate, rather than teacher support, could moderate the association between inquiry-based science activities and student science achievement for both genders. Implications for instruction and further research were discussed as well.  相似文献
