Gobert, Janice D.; Sao Pedro, Michael; Raziuddin, Juelaila; Baker, Ryan S. – Journal of the Learning Sciences, 2013
We present a method for assessing science inquiry performance, specifically for the inquiry skill of designing and conducting experiments, using educational data mining on students' log data from online microworlds in the Inq-ITS system (Inquiry Intelligent Tutoring System; www.inq-its.org). In our approach, we use a 2-step process: First we use…

Wanstreet, Constance E.; Stein, David S. – American Journal of Distance Education, 2011
This study investigated the small-group, learner-led discussion process in synchronous discussions. Transcripts from online chats and face-to-face discussions were analyzed within the context of the Community of Inquiry framework to examine the relationship of teaching presence, social presence, and cognitive presence to one another and for…

Methodological Issues in Developing a Multi-Dimensional Coding Procedure for Small-Group Chat Communication
Peer reviewed Peer reviewed

Strijbos, Jan-Willem; Stahl, Gerry – Learning and Instruction, 2007
In CSCL research, collaboration through chat has primarily been studied in dyadic settings. This article discusses three issues that emerged during the development of a multi-dimensional coding procedure for small-group chat communication: (a) the unit of analysis and unit fragmentation, (b) the reconstruction of the response structure and (c)…

Beers, Pieter J.; Boshuizen, Henny P. A.; Kirschner, Paul A.; Gijselaers, Wim H. – Learning and Instruction, 2007
CSCL research has given rise to a plethora of analysis methods, all with specific analysis goals, units of analysis, and for specific types of data (chat, threaded discussions, etc.). This article describes some challenges of CSCL-analysis. The development of an analysis method for negotiation processes in multidisciplinary teams serves as an…

Revisiting Methodological Issues in Transcript Analysis: Negotiated Coding and Reliability
Peer reviewed Peer reviewed
Direct linkDirect link
Garrison, D. R.; Cleveland-Innes, M.; Koole, Marguerite; Kappelman, James – Internet and Higher Education, 2006
Transcript analysis is an important methodology to study asynchronous online educational discourse. The purpose of this study is to revisit reliability and validity issues associated with transcript analysis. The goal is to provide researchers with guidance in coding transcripts. For validity reasons, it is suggested that the first step is to…
