This paper explores the role of instructional scaffolding in the development of undergraduate students' understanding of mathematical proof during a one-year discrete mathematics course. We describe here the framework adapted for the analysis of wholeclass discussion and examine how the teacher scaffolded students' thinking. Results suggest that students who engage in whole-class discussions th...

Based on constructivist learning theories, this study focused on examining the use of an online discussion board in a graduate course as a place where forty-six inservice teachers could share experiences and ideas. Discussions held outside class were conducted by computer conferencing software. Data collection focused on online discussion transcripts of all the messages for three separate weeks...

Most colleges and universities have adopted course management systems (e.g., Blackboard, WebCT). Worldwide faculty and students use them for class communications and discussions. The discussion tools provided by course management systems, while powerful, often do not offer adequate capabilities to appraise communication patterns, online behaviors, group processes, or critical thinking. This pap...

The cues undergraduate biology instructors provide to students before discussions of clicker questions have previously been shown to influence student discussion. We further explored how student discussions were influenced by interactions with learning assistants (LAs, or peer coaches). We recorded and transcribed 140 clicker-question discussions in an introductory molecular biology course and ...

Housing represented a field of interest that gradually acquired wider significance within the framework social policy in interwar Czechoslovak Republic. While until creation independent state 1918, discussions on housing focused primarily working class, rise new middle class years created […]

The Beowulf class of parallel computing machine started as a small research project at NASA Goddard Space Flight Center’s Center of Excellence in Space Data and Information Sciences (CESDIS). From that work evolved a new class of scalable machine comprised of mass market common off-the-shelf components (MCOTS) using a freely available operating system and industry-standard software packages. A ...

Data from whole-class discussions in Dutch upper primary school show that teachers occasionally explicitly take downgraded epistemic stances through disclaimers such as ‘ik weet het niet’ (English: I don’t know (it)), which contrasts with their institutionally assigned authority. In the current study, we have collected turns occur, and analysed them using conversation analysis. our analyses, fo...
