Integrating disciplinary-specific genre structure in discourse strategies to support disciplinary literacy

Classroom discourse plays an important role in shaping how students learn science in the classroom. Past research has examined how content area teachers use a variety of generic discourse strategies to foster classroom interaction and content mastery. However, few have focused on how teachers’ discourse strategy can be used in more specific ways to build subject-specialized genres of the discipline, such as scientific explanation. The purpose of this study is to examine how science teachers integrate disciplinary-specific genres in their discourse strategies to engage their students in thinking about the conceptual and epistemic aspects of the discipline. Through a three-year design research, four science teachers learned a genre-based instructional method designed to explicitly teach students how to construct scientific explanations. Lesson observations from these teachers before and after they learned the genre-based instruction were video-recorded and analyzed. It was found that with the incorporation of the genre-based instructional method, a discourse strategy that we call meta-discoursing was employed in ne w ways to facilitate the teaching of the explanation genre. Using multiple exemplars, we describe the ways in which this discourse strategy was enacted in tandem with the genre-based instructional method to facilitate disciplinary literacy through classroom talk

ELL\u27s science meaning making in multimodal inquiry: A case-study in a Hong Kong bilingual school

This paper reports on a multimodal teaching approach delivered to grade 5 elementary students in a bilingual school in Hong Kong, as part of a larger research study aimed at supporting English Language Learners (ELLs) in science class. As language demands of reading, writing and talking science place additional challenges on ELLs, there is much research interest in exploring the use of multiple modes of communication beyond the dominant use of verbal and written language. Research has shown that students develop a better scientific understanding of natural phenomena by using and alternating between a variety of representations. Yet, questions remain as to what meanings ELLs make during a multimodal discourse and, in turn, how such discourse provides support to ELLs in learning science. Drawing on social semiotics, which theorizes language as a meaning making resource comprising a range of modes (e.g. gestures and diagrams), we used a case-study approach to examine how a multimodal instructional approach provided 10 students with multiple avenues to make sense of science learning. Video recordings (capturing gestures, speech and model manipulation) and student works (drawing and writing) were collected during nine inquiry science lessons, which encompassed biology, physics and chemistry science units. Multimodal transcription allowed discourse to be analysed at a fine-grain level which, together with analysis of student works, indicated that the multimodal instructional approach provided the necessary inquiry opportunities and variety of language experiences for ELLs to build science understandings. Analysis also revealed how the affordances of modes attributed to the meaning making potentials for the ELLs and how they provided alternate communication avenues in which new meanings could be made. The findings from this study have implications for ELLs learning science within the growing multilingual Asia-Pacific region

Plan-Draw-Evaluate (PDE) pattern in students' collaborative drawing: Interaction between visual and verbal modes of representation

The use of group drawing to promote student-generated representation is a common instructional strategy as it combines the benefits of using visual representation and collaborative talk. Although the affordances of group drawing have increasingly been emphasized in science education, few studies have investigated how drawing as a visual mode interacts with group discourse as a verbal mode as well as how that interaction facilitates the development of students' collective ideas. Informed by theories in classroom discourse and multimodality, this paper examines the interaction process between a verbal and visual mode of representation as groups of students engaged in collaborative drawing during guided science inquiry lessons. On the basis of the analysis of data from a science class that adopted group drawing, we found and documented a recurring pattern, Plan-Draw-Evaluate or PDE pattern, in how the interaction between the verbal and visual modes occurred during collaborative drawing. This PDE pattern consisted of a triad of moves that alternate between the two modes and fulfilled various discursive purposes, such as suggesting, requesting, recording, visualizing, elaborating, agreeing, and rejecting. The PDE pattern provided a basic social structure that facilitated the collaboration and progression of students' ideas. With illustrations of PDE patterns and its variations, we argue that the PDE pattern provides an insight into the dynamic organization of interactions involved in group drawing that takes into consideration the multimodal affordances of verbal and visual modes of representation and the progression of ideas developed through collaborative discourse

Analysing Interaction in Science Classrooms

One central issue for research in classrooms is to provide insights concerning characteristics of classroom interaction that can help teachers improve their teaching. In the present study, we analyse spoken interaction in one elementary physics classroom by the use of two different frameworks, targeting similar aspects of social communication, namely how discourse patterns shape the relations between participants. The two frameworks utilized are on the one hand analyses of the communicative approach according to Mortimer and Scott, combined with analyses of discourse patterns such as IRE-patterns, and on the other hand analyses related to the interpersonal meta-function in Halliday’s systemic-functional grammar, SFG. The aim was to highlight possibilities and limitations of the different frameworks.  Our analyses reveal that the two analytical frameworks have partly the same, partly different affordances concerning what they can reveal about classroom interaction. The analyses of the communicative approaches have the potential of elucidating discursive patterns and power relations at a general level, while the analyses based on SFG can provide more details about the power relations in terms of how the participants actually structure their utterances. The results are also discussed regarding implications for education

The role of language in scaffolding content & language integration in CLIL science classrooms

This commentary to the special issue “Teaching, Learning and Scaffolding in CLIL Science Classrooms” synthesizes the contributions from the authors by addressing two overarching questions. First, what is the role of language in mediating science teaching and learning in a CLIL science classroom? Second, to what extent can content and language be integrated or separated in CLIL instruction and assessment? In addressing the first question, I distil three major perspectives of how the authors conceive the role of language as a scaffolding tool. These roles are: (a) providing the discursive means and structure for classroom interaction to occur, (b) enabling students’ construction of knowledge through cognitive and/or linguistic processes, and (c) providing the semantic relationships for science meaning-making. These three perspectives roughly correspond to the discursive, cognitive-linguistic, and semiotic roles of language respectively. In addition, two other roles – epistemic and affective, though not emphasized in this issue, are also discussed. In addressing the second question, I raise a dilemma concerning the integration of content and language. While there are clear political and theoretical arguments calling for an inseparable integration, there is also a common practice to separate content and language as distinct entities for various pedagogical and analytical purposes. In revolving this conundrum, I suggest a way forward is to consider the differences in the various roles of language (discursive/cognitive/linguistic vs. semiotic/epistemic/affective) or the levels of language involved (lexicogrammar vs. text/genre)

How is disciplinary literacy addressed in the science classrooms? A Singaporean case study

Disciplinary literacy is the specific ways of talking, reading, writing, and thinking valued and used by people in a discipline in order to successfully access and construct knowledge in that discipline. This paper reports on a case study of the classroom practices of two physics and two chemistry teachers in Singapore in order to better understand how disciplinary literacy is currently addressed in the teaching of secondary school science. The study found that disciplinary literacy in science teaching was limited to the language aspects of science terminologies and the literacy practice of constructing explanation. Even then, these disciplinary language aspects were only implicitly embedded within the predominant practice of teacher-led talk. Based on these findings, current realities and future possibilities of disciplinary literacy instruction building on science teachers' current teaching practices are discussed

Shifts in Identification in a Hybrid Space

In a hybrid space where people enact multiple identifications across time and space, this paper examines the question of why and how students shift from one identification to another in school. Through a design-based research in a high school physics classroom enacted to bring about a convergence of students’ out-of-school discourses and school-based discourse, I analyzed the nature of identification undertaken by some students as they navigated multiple discourses. Using Bakhtin’s work as an analytical frame, I suggest that shifts in identification should be seen as a temporary appropriation of a dialogic other’s voice (or ideological stance) and suppression of one’s preferred voice that is performed strategically according to one’s situated interest at any particular point in time
