Background: Teachers are expected to take actions that support students' ideas and create a network of ideas between different ideas when classroom discourse is based on an interactive dialogic communicative approach. Despite this emphasis, it is unknown how well existing discourse approaches and moves used in science education research correspond…

The purpose of this study was to examine the ways in which teachers use language to promote vocabulary development (i.e., vocabulary talk moves) during science instruction in early-elementary classrooms. Twenty-four total science lessons were recorded by eight teachers, providing 894.27 min of observational data across three timepoints. Discourse…

The importance of using dialogue as a pedagogical tool to enhance student learning in science has been widely recognised in research literature. Effective classroom dialogue is dependent upon teaching which successfully engages students in critical thinking and deep learning, requiring many teachers to think and work differently in science…

Research indicates that dialogic teaching promotes students content understanding, learning engagement, and democratic participation in classroom discussion. However, dialogic teaching is often misconstrued as a challenge for multilingual learners because there is a tendency to view them as lacking English language proficiency for sustained…

It has been suggested that students' epistemic understandings influence their practice of argumentation. However, how that influence takes place is not yet fully explained. To contribute to the answer to this question, this study explored elementary students' epistemic understandings in their scientific argumentation. A 4-month qualitative case…

The discipline of science provides rich opportunities for language development as students engage collaboratively to investigate and make sense of compelling phenomena. Drawing from a design research study conducted in fifth grade classrooms, we describe how teachers can support emergent multilingual students' participation in science discourse.…

Instructor discourse, defined as verbal interactions with students in the classroom, can play an important role in student learning. Instructors who use dialogic discourse invite students to develop their own ideas, and both students and the instructor share ideas in back-and-forth exchanges. This type of discourse is well-suited to facilitate…

This paper addresses a problem that greatly complicates the implementation of dialogic educational approaches in schools: the dilemma between driving children's talk towards normatively accepted conceptions and, at the same time, avoiding the introduction of these normative conceptions into the dialogue by the teacher. I argue that this dilemma is…

Background: Discourse is the teacher's principal pedagogical tool in class. Studies stress the importance of research on discourse in science education and demonstrate its cruciality for understanding science. Purpose: The purpose of this study was to investigate characteristics of the classroom discourse in lessons on physics. Sample: Classroom…

This case study presents the analysis of teacher-student interaction in physics classrooms. The participants of the study were three physics teachers and 131 students from three upper primary schools (Grades 7 and 8) of Ethiopia. Data for the study were collected through observation of eight video recorded physics lessons. The analysis of videos…

Research from the fields of science representation, genre pedagogy and disciplinary literacy for adolescents indicates that achievement for students, including those from linguistically diverse backgrounds, will improve if they engage with the meaning-making conventions of disciplinary texts, but there is no current agreement on the nature of…

In this study, we have explored the ways in which small-group work in science can contribute to strengthen multilingual students' subject language and conceptual development when working with language-oriented classroom activities in primary classrooms. The aim is to determine whether it is possible to identify factors in interactions in…

Due to benefits for teaching and learning, an increasing number of studies have focused on classroom dialogue and how to make it productive. Coding, in which the transcribed conversation is allocated to a set of features, is commonly employed to deal with the textual data arising from this dialogue. This is generally done manually and cannot…

To understand students' argumentation abilities, there have been practices that focus on counting and analyzing argumentation schemes such as claim, evidence, warrant, backing, and rebuttal. This analytic approach does not address the dynamics of epistemic criteria of children's reasoning and decision-making in dialogical situations. The common…

This manuscript elaborates the value of looking beyond the written and spoken word in science education research and practice at the early childhood level. We examine one plurilingual child's descriptions of a science activity to explore the "diversity of resources" that she used while expressing her understandings of a sound…
