The exclusive language of science? Comparing knowledge gains and motivation in English-bilingual biology lessons between non-selected and preselected classes

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.     

Pupils’ attitudes towards foreign-language learning and the development of literacy skills in bilingual education

The study investigated the effects of bilingual teaching on the development of children's literacy skills and attitudes towards language learning. In the bilingual classes 20% of the instruction was given in English. Pupils’ literacy skills in the bilingual classes were significantly better than in the monolingual classes. When observing pupils who started first grade with either a poor or an excellent level of school readiness, there was no significant difference between bilingual and monolingual groups. In addition, the pupils in bilingual classes showed significantly more positive attitudes towards foreign-language learning than the pupils in monolingual classes.     

Effects of CLIL on second language learning: Disentangling selection,preparation, and CLIL-effects

The positive effects of Content and Language Integrated Learning (CLIL) on the development of students’ foreign language skills may have been overestimated by previous studies, since most studies failed to consider selection and preparation effects appropriately. Therefore, the present study used complete survey data from a 2002–2007 cohort to investigate English skill development of N = 385 German CLIL and N = 5,578 non-CLIL grammar school students from grade seven (M = 12.46, SD = 0.53) to grade eight (M = 14.46, SD = 0.53). Firstly, we found significant selection effects for performance in primary school, sociodemographic variables, and cognitive abilities. Secondly, after propensity score matching, data revealed significant preparation effects of additional second language instruction for the CLIL students. When controlling selection and preparation effects, only a small and non-significant CLIL effect occurred measured by a C-test. We discuss the results with regard to previous inconsistent findings.

Critical perspectives on testing teaching: reframing teacher education for English medium instruction

The investigation reported here provides a basis for considering the role of corrective and transformative critiques in producing knowledge through testing teaching for reframing teacher education in response to, and as an expression of, the globalisation of English. This knowledge-producing approach to critique begins with a literature review of prior testing models of content and language integrated learning through English medium instruction (EMI) programmes. Delphi procedures were employed with a panel of 30 experts from three focus groups, namely teachers, testing experts, and teacher evaluation administrators. A comparison of relative importance of the indicators generated through this study via the analytic hierarchy process yielded practical implications for reframing the internationalisation of education using EMI. The analysis of interviews with teachers was used to critically rework or otherwise correct the testing model. Through adopting the practice of critique as a knowledge-producing venture, this study offers a model of EMI testing that can contribute to improvements in the organisation of professional learning and change, as well as certification procedures.

Effects of active‐learning experiences on achievement,attitudes, and behaviors in high school biology

Active‐learning labs for two topics in high school biology were developed through the collaboration of high school teachers and university faculty and staff and were administered to 408 high school students in six classrooms. The content of instruction and testing was guided by State of Texas science objectives. Detailed teacher records describing daily classroom activities were used to operationalize two types of instruction: active learning, which used the labs; and traditional, which used the teaching resources ordinarily available to the teacher. Teacher records indicated that they used less independent work and fewer worksheets, and more collaborative and lab‐based activities, with active‐learning labs compared to traditional instruction. In‐class test data show that students gained significantly more content knowledge and knowledge of process skills using the labs compared to traditional instruction. Questionnaire data revealed that students perceived greater learning gains after completing the labs compared to covering the same content through traditional methods. An independent questionnaire administered to a larger sample of teachers who used the lab‐based curriculum indicated that they perceived changing their behaviors as intended by the student‐centered principles of the labs. The major implication of this study is that active‐learning–based laboratory units designed and developed collaboratively by high school teachers and university faculty, and then used by high school teachers in their classrooms, can lead to increased use of student‐centered instructional practices as well as enhanced content knowledge and process learning for students. © 2007 Wiley Periodicals, Inc.

Teacher professional development through collaborative action research: impact on foreign English-language teaching and learning

In 2011 we, a group of English-as-a-foreign-language teachers at a secondary school in Argentina, decided to investigate our teaching practices through collaborative action research so as to improve our students’ learning opportunities and thus revitalise English-language teaching in our context. We implemented and evaluated the integration of content and language learning in our classrooms through the development of our own materials. The experience revealed a growth in professional development and how our motivation and autonomy influenced our students’ motivation and language development. In our attempt to disseminate our experience as a group, this report particularly focuses on the evaluation facets of our collaborative action research project so as to encourage other teachers and teacher-researchers to adopt collaborative action research to improve their own practices.     

Motivation in high school science students: A comparison of gender differences in life,physical, and earth science classes

The aims of this study were to examine self‐efficacy and other motivation variables among high school science students (n = 502); to determine the degree to which each of the four hypothesized sources of self‐efficacy makes an independent contribution to students' science self‐efficacy beliefs; to examine possible differences between life, physical, and Earth science classes; and to investigate patterns of gender differences that may vary among the fields of science. In Earth science classes, girls earned higher grades and reported stronger science self‐efficacy. In life science classes, girls earned higher grades but did not report stronger self‐efficacy, and did report higher science anxiety. In physical science, there were no gender differences in grades or self‐efficacy, but girls again reported higher levels of science anxiety. For boys across science fields, science self‐efficacy significantly predicted course grades and mastery experiences was the only significant predictor of self‐efficacy. For girls, self‐efficacy was also the strongest predictor of science grade across fields. Mastery experiences significantly predicted self‐efficacy in Earth science for girls, but social persuasions, vicarious experiences, and physiological states were better predictors of science self‐efficacy in life and physical science classes. Results support (Bandura, A., 1997) hypothesized sources of self‐efficacy, previous research findings on self‐efficacy in the domain of science, and validate the suggestion made by Lau and Roeser (2002) to disaggregate data by science field. © 2008 Wiley Periodicals, Inc.

Language and content ‘integration’: the affordances of additional languages as a tool within a single curriculum space

‘Language across the curriculum’ has been pivotal in establishing a knowledge base on the role of language for accessing opportunities afforded by the curriculum. Yet, the ubiquity of language within all facets of human activity – not least of all the more abstract domains of thinking and relating with others – can easily obscure its perceptibility as an object for research relative to other priorities; especially when the curriculum focus is directed towards content-oriented areas, such as mathematics or the humanities. This paper uses an ecological framework to consider the place of language when the teacher’s focus is not solely on language, or content, but is equally attentive to both through a relatively new approach to theorizing learners’ non-native language within the curriculum: content and language integrated learning. In particular, it critically examines the notion of ‘integration’ as a pedagogical assumption for working with language in curriculum domains by focusing on teachers’ perceptions of the affordances of language as a meditational tool within the classroom space. Findings raise new implications for understanding the role of language(s) within the curriculum, and are significant for addressing the needs of a changing, globalized student demographic where the presence of multiple languages will increasingly shape learners’ engagement with the curriculum.

Negotiation,embeddedness, and non-threatening learning environments as themes of science and language convergence for English language learners

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.

The impact of an integrated approach to science and literacy in elementary school classrooms

This study investigates the efficacy of an integrated science and literacy approach at the upper‐elementary level. Teachers in 94 fourth grade classrooms in one Southern state participated. Half of the teachers taught the treatment unit, an integrated science–literacy unit on light and energy designed using a curriculum model that engages students in reading text, writing notes and reports, conducting firsthand investigations, and frequent discussion of key concepts and processes to acquire inquiry skills and knowledge about science concepts, while the other half of the teachers taught a content‐comparable science‐only unit on light and energy (using materials provided by their districts) and provided their regular literacy instruction. Students in the treatment group made significantly greater gains on measures of science understanding, science vocabulary, and science writing. Students in both groups made comparable gains in science reading comprehension. © 2012 Wiley Periodicals, Inc. J Res Sci Teach 49: 631–658, 2012     

The process,dialogues, and attitudes of vocational engineering high school students in a web problem-based learning (WPBL) system

This study aims to explore how high school students collaboratively solve problems in a web problem-based learning (WPBL) system in an 8-week digital logic course using discourse analysis. Employing in-depth interviews, this study also investigated the students' attitudes toward the WPBL system. The number of teaching assistants' responses had a negative relationship with the number of peer responses. Regarding dialogue quality, extended questions and brainstorming stimulated each other. Elaboration facilitated problem solving, whereas organizing knowledge from books or websites decreased reflection. Students affirmed the usefulness and effectiveness of the web system because it created an interactive, flexible, comfortable and collaborative learning environment.     

English language acquisition and educational attainment at the end of secondary school

There has been relatively little empirical research on the impact of stage of fluency in English of bilingual pupils. However, this issue is increasingly important given growth in the bilingual school population in England of over one‐third between 1997 and 2004 to around 10% of the school population. This study evaluates the relationship between stage of English fluency and performance in public examinations at age 16 for all pupils within an inner London local education authority. Two methodological approaches are used to study the associations. The first looks at the context and the trend data for the case‐study local authority (LEA) in terms of languages spoken and the performance of bilingual pupils in schools. This is followed by a detailed statistical regression analysis to isolate the unique association between level of fluency in English and pupils' performance at age 16, after controlling for the effect of a range of other pupil and school background factors. The results confirm a strong relationship between stage of fluency in English and educational attainment, with the performance of bilingual pupils increasing as measured stage of fluency in English increases. Pupils in the early stages of fluency perform at very low levels, while bilingual pupils who are fully fluent in English perform better, on average, than English‐only speakers. However, the latter results are not due to bilingualism per se since the difference is no longer statistically significant after controlling for other measured pupil background variables. All EAL (English as an Additional Language) pupils make better than expected progress over the two years between age 14 and age 16. The final section questions the appropriateness of the Qualification and Curriculum Authority's (QCA) approach to the assessment of bilingual pupils, which contrasts with the local authority's good practice. Based on the findings of this study, we argue that there is a need to develop a national assessment strategy that better meets the needs of bilingual learners. The policy implications for national and local government and for school improvement practitioners are reviewed.     

Design,implementation, and evaluation of an ePortfolio approach to support faculty development in vocational education

This article provides an account of the design, implementation, and evaluation of an ePortfolio approach to faculty development and performance evaluation at a Canadian post-secondary vocational education institute. The approach was piloted in two phases in 13 departments. Survey and interview data were collected and analyzed to determine adoption, reception by faculty, and impact of the approach on faculty development. While adoption of the approach in the pilots was limited, participants who adopted the approach reported collecting more and different feedback, developing increased awareness of areas for improvement, and planning their professional learning more explicitly. Further studies are needed to determine what design elements of the portfolio optimally support professional development and performance evaluation.
