Abstract

In Content and Language Integrated Learning (CLIL) contexts, students are expected to express disciplinary knowledge in a second/foreign language. One construct that has proven useful for the identification and realization of language functions in disciplinary knowledge is Dalton-Puffer’s (2013) model of cognitive discourse functions (CDFs). Additionally, Systemic Functional Linguistics (SFL) has already been proven useful for distinguishing lexico-grammatical features that characterise different CDFs in CLIL students’ productions (e.g., Nashaat-Sobhy & Llinares, 2020; Evnitskaya & Dalton-Puffer, 2020). In this article, we use SFL to analyse the oral and written realisations of the CDF Define by 6th grade students participating in a CLIL program in Madrid, Spain. A total of 83 students responded to the same prompt (on science) in writing (in the form of a blog) as well as orally (in the form of an interview). In the oral interviews the co-construction of definitions by the students with the interviewer (researcher) and another peer are explored using the notion of Legitimation Code Theory and the concept of semantic waves (Maton, 2013). The analysis of students’ definitions is also related to primary CLIL teachers’ evaluations using comparative judgement.

什么是生态系统？

在内容和语言综合学习（CLIL）环境中，学生需要用第二语言/外语表达学科知识。Dalton Puffer（2013）的认知话语功能模型已被证明对识别和实现学科知识中的语言功能有用。此外，系统功能语言学（SFL）已经被证明有助于区分CLIL学生作品中不同CDF的词典语法特征（例如，Nashaat Sobhy&Llinares，2020；Evnitskaya和Dalton Puffer，2020）。在本文中，我们使用SFL来分析在西班牙马德里参加CLIL项目的六年级学生对CDF Define的口头和书面实现。共有83名学生以书面（博客形式）和口头（采访形式）回应了同样的提示（关于科学）。在口头访谈中，学生与访谈者（研究人员）和另一位同行使用合法化代码理论的概念和语义波的概念来探讨定义的共同构建（Maton，2013）。对学生定义的分析也与小学CLIL教师使用比较判断的评价有关。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
