Welcome to my website! I am a researcher and professor of information science. My current research focuses on the Virtual Math Teams (VMT) project at Drexel's i-School and the Math Forum. Our research team uses chat interaction analysis to explore what takes place in online discussion of math by students. The background and motivation for this research in my previous research from 1990 to 2005 is presented in my book on Group Cognition.

My specialty is Computer-Supported Collaborative Learning (CSCL). I am the founding Executive Editor of the International Journal of CSCL (ijCSCL). I have presented at every international CSCL conference (1995, 1997, 1999, 2001, 2002, 2003, 2005, 2007) and have collected many resources about CSCL on my website.

All of my own publications are available on this site, listed chronologically. My CV details my academic career. My grants and research during the past 20 years are documented on this site. At Colorado and Drexel I have taught courses on CSCL and Human-Computer Interaction (HCI)--how to design software to support collaborative learning, knowledge building and group cognition by online groups. My website also includes glimpses into my biography and personal life.

VMT Research Project VMT

Virtual Math Teams (VMT) is a research project that I have directed since its inception in 2003 at the i-School and the Math Forum at Drexel University in Philadelphia. A group of PhD students, Math Forum staff, interdisciplinary faculty and visiting researchers collaborate on the project. We are developing an online service for math students to meet in small groups online to discuss challenging mathematical topics. We study the usage of the technological environment that we designed for this service, using a method of chat interaction analysis that we have refined. The project is guided by theories of collaborative learning, community knowledge building and group cognition, that we are exploring.

If you register and log into the VMT Lobby, you can enter the VMT Sandbox room to explore the functionality available there. You can also join a chat room or even create one to invite people to for collaborative online chats. There is an introduction to VMT for students, parents, teachers and researchers at the Math Forum VMT web page. A list of publications about the VMT project is also available there.

Here are some recent papers by the VMT research team:

Group Cognition Book book cover

I published Group Cognition: Computer Support for Building Collaborative Knowledge in 2006. The book includes 21 chapters that review and extend my research during the past decade. The chapters report on several projects to develop software systems (including AI support for group formation, summarization and interanimation of perspectives), on approaches to analyze computer-mediated small-group interactions and on theoretical reflections leading to the notion of group cognition as foundational for collaborative learning.

The 500 page book is published by MIT Press and is available for a reasonable price from the following sources:

The ijCSCL Journal cover

The International Journal of Computer-Supported Collaborative Learning (ijCSCL) was founded in 2006 to provide a venue for publication of leading papers on CSCL research. I co-founded the journal with Friedrich Hesse, the director of the Knowlede Media Research Center in Tuebingen, Germany, and with a Board of Editors including about 40 leading CSCL and CSCW researchers from around the world. The journal is published quarterly by Springer, sponsored by the International Society of the Learning Sciences. Anyone who joins ISLS is entitled to receive paper and electronic copies of the journal. To join ISLS, go to ISLS.org. The ISLS membership fee is deducted from registration at the CSCL or ICLS conference. Most major universities subscribe to ijCSCL as part of Springer's package of educational journals. The full text of all papers in ijCSCL are available for free at ijCSCL.org. For instructions on submitting a paper to ijCSCL, go to ijCSCL.org. A book review and the introductions to previous issues are available on my ijCSCL page

CSCL Resources cscl logo

I have tried to gather some resources for people interested in Computer-Supported Collaborative Learning and for the community of CSCL researchers. I wrote some overviews of the field from my perspective:

...an overview of the history and issues of CSCL. It provides numerous references for further study and outlines a direction for future work. The view of CSCL, its origins and its future is very much a particular perspective -- that of the authors.

I post a CSCL-Community blog. I compiled a list of CSCL books on Amazon, I contributed to Wikipedia articles:

My Publications books

My publications are available here organized in a couple of ways. The most up-to-date and useful is the chronological listing. My older writings are categorized by genre; this collection includes informal essays, grant proposals and other materials that are not all included in the chronological list. My CV organizes my professional publications by type and peer-review status. I try to make all of my publications freely available on this site in full text, searchable by Google and Scholar.

I am currently working on two books related to group cognition in the Virtual Math Teams Project:

An edited volume in Springer's CSCL book series: Studying Virtual Math Teams.
A collection of papers by the VMT research team and collaborating researchers, including case studies, theoretical reflections and methods of analyzing and representing online interaction.

A monograph in MIT Press's Acting with Technology book series: Explorations of Group Cognition.
An extended fine-grained analysis of a four-hour VMT session among three math students.

My HCI Courses gerry

My courses are heavily computer-supported. A consequence of this is that the course materials and even the student work is freely available for everyone to share. My teaching at Colorado and Drexel is documented on my teaching page. Recent courses on designing Web 2.0 software to support collaborative learning, community knowledge building and group cognition are completely documented on their wiki sites:

Spring 2007, HCI: Designing Social Interaction Software.
...designing software to support the VMT user community.

Winter 2008, HCI: Designing IPL Social Interaction.
...designing software to support the Internet Public Library.

Spring 2008, HCI: Designing for CSCL.
...designing software to support the CSCL research community.

My Research History vmt eloc

Although most of my research during the past several years has been related to the VMT project, I worked on a variety of projects earlier. Since the development of the Web I have documented my research on my website:

Research at Drexel. grant proposals at Drexel and the Math Forum

Research in Europe ITCOLE project, BSCL, Synergia

Research in Colorado WebGuide, State the Essence, Organizational Memory, Articulate Learners, Gamble Gulch, L3D Lab, Communications Theory

Research previously Hermes, OMOL, WebNet, CIE, TCA, CREW, OptoNet, consulting and programming

My curriculum vitae (in HTML Web and PDF printing formats) contains exhaustive listings of my academic activities, with links to the original source documents. For my tenure review in Fall of 2007, I compiled additional documentation of my activities at Drexel for internal and external review.

Biographical family

In the mid-1990's, when the Web was young, I started my website in much the same format as it has now. I experimented with including both professional and family materials on the same site. As you can see from the archived versions of my site from 1997, 2000, 2002, 2005, 2009, it has maintained that format for over a decade now. The site still includes biographical data about my education and pictures of friends, family, home, recreation and leisure time activities, including a gallery of my sculpture.
