The study of pivotal teaching moments (PTMs) offers significant insights into mathematics classroom interactions. PTMs are student-generated instances within a lesson that provide opportunities for teachers to modify planned instruction (Stockero & Van Zoest, 2013). Given the importance of interactions and discourse in students' mathematical…

This study presents an in-depth exploration of the types of discursive functions of teacher questioning and the potential cognitive correspondences embedded in the questioning. The participants were a science teacher and his class of 26 sixth-grade students who were engaged in an immersion science inquiry activity. The major data source was a…

Communicating their thinking in mathematics is challenging for young children. This research studied the change in six-year old students' oral and written solution explanations before and after six problem-based mathematics lessons that focused on developing conceptual understanding of adding or subtracting a 2-digit number and a multiple of ten.…

This paper uses multimodal discourse analysis to show that discursive form, in addition to words, gestures and sound dimensions of speech, is an important linguistic resource for expressing mathematical meaning. During a collaborative task, a student spoke an insight about an algebraic property five times over a few minutes, in slightly different…

Peer moderation has been used as a beneficial strategy in asynchronous online discussions to assist student learning performance. However, most studies in peer-moderated asynchronous online discussions (PMAOD) have focused only on learning effectiveness and perceptions of students rather than on students' knowledge dimensions and cognitive…

This article is an early step in the development of a methodological approach to the study of language deriving from an enactivist theoretical stance. Language is seen as a co-ordination of co-ordinations of action. Meaning and intention cannot easily be interpreted from the actions and words of others; instead, careful attention can be placed in…

Presents a case study with two objectives: (1) the identification of the interactions between pairs of 16- and 17-year-old students related to problem solving, and (2) the influence of such interactions in their cognitive development. Concludes that the interactions significantly influenced the individual development of cognitive and heuristic…

In this article, we articulate the critical differences between memory-based processing and explanation-based processing. We suggest that the most important claim of memory-based text processing is that the automatic processes that function with respect to text processing are all applications of ordinary memory processes. This claim contrasts with…

Reports findings from three experiments designed to show how readers inferred spatial information relevant to a story character's movements through a previously memorized layout of a fictional building. Examines how inference measures are related to spatial imagery. (HB)

Examines the student and professional discourse within the same field through a set of case studies written for a third-year course in financial analysis. Reports on the distinct social actions undertaken by student writers as compared with professional practices. Shows commonalities of student and workplace writing. (HB)

Discusses two sets of neurological case histories: A. R. Luria's "The Man with a Shattered World," and Oliver Sack's "Awakenings." Argues that these histories display two paradigmatic explanations for the mind/brain relation, and that the movement from one paradigm to another also necessitates a movement to different forms of…

Examines the reading processes and practices of one female college student through eight semesters of undergraduate education. Traces the student's beliefs about literate activity. Analyzes the student's conceptions of the functions of texts and authors as they grew in complexity. (HB)

Examines the in-class essay as written by university freshmen to assess the extent to which students use formulaic expressions to minimize the cognitive burden of generating a coherent and adequate answer. Results show that students made extensive use of formulaic expressions and shaped their answers to reflect the way the information had been…

Reports on two lab experiments which explored how undergraduate students process arguments and cues under ambiguous and uncertain conditions. Asks whether students use simultaneous processing or prefer exclusive processing. Indicates that students prefer exclusive processing, with no support for simultaneous. (HB)

Argues for an activity-based theory of genre knowledge. Provides data from case study research concerning "insider knowledge" about genres of academic cultures. Proposes five general principles as a basis for a theory of genre. (HB)
