The idea of personalizable software is fashionable today. I explored it in a number of software prototypes a decade or two earlier. The perspectives mechanism in Hermes, my dissertation software system, was an initial major initiative in this direction. WebNet was a follow-up system to integrate the perspective mechanism into discussion-forum collaboration software. Subsequent systems explored personalization mechanisms in systems for work and for learning, including TCA for teachers developing and sharing curriculum and systems for automated critics in design systems or reviewers of journal articles. In each case, the mechanisms were intended to support users to view and discuss materials from their personal perspectives and to share those views with others to encourage building group perspectives. The volume is organized in terms of essays on (a) structured hypermedia, (b) personalizable software, (c) software perspectives and (d) applications to health care, education and publishing.

The current volume is intended to provide an overview of the eLibrary and some documentation of my life as the author of these texts.

Essay Collection covering the point where software, law and social justice meet.

The interdisciplinary field of Computer-Supported Collaborative Learning (CSCL) explores ways of making learning more engaging, stimulating, and effective by promoting collaboration among learners through the use of computer networking, simulations, and computational support. This volume reproduces the editorial introductions to the International Journal of Computer-Supported Collaborative Learning (ijCSCL) since its beginning in 2006. The introductions situate the articles in each quarterly issue within current CSCL research activity and highlight the unique perspectives and important contributions of the included papers. The introductions also present reflections on topics of CSCL theory and methodology, providing concise contributions of their own. Written in different styles, the introductions as an ensemble provide a lively, stimulating introduction to the CSCL research field as it has grown over the years.

Leading with the provocative observation that writing programs administration lacks ¿an established set of texts that provides a baseline of shared knowledge . . . in which to root our ongoing conversations and with which to welcome newcomers,¿ Landmark Essays on Writing Program Administration focuses on WPA identity to propose one such grouping of texts. This Landmark volume is the cornerstone resource for new Writing Program Administrators and graduate students seeking an ever-important overview of the literature on Writing Program Administration. Drawing broadly across scholarship in writing programs and writing centers, Ritter and Ianetta work to historicize, theorize, and problematize the ever-shifting answers offered to the question: Who¿or what¿is a WPA?

My career has usually been funded by grants. Here are some of the proposals I wrote at the University of Colorado and at Drexel University. Successful grant proposals are tricky to write. The ones reproduced here might provide helpful examples. They may also provide explicit statements of some of the goals of my research over the years.

Math games and workbooks with topics for online small groups of teachers or students to collaboratively learn dynamic geometry. The approach is based on "Translating Euclid." The many GeoGebra files used in VMT courses are pictured in the workbook. Several versions of the workbooks are available, including the version used in WinterFest 2013 and analyzed in "Translating Euclid" and "Constructing Dynamic Triangles Together." Also includes the content of a game version that is available as a GeoGebraBook.

This volume contains information on Gerry StahlÕs sculpture and other artistic creations. There are reflections on his approach to sculpture, both aesthetic and technical. The volume concludes with a catalog of all the sculptures in chronological order.

PhD dissertation in computer science about software environments to support collaborative design, facilitating multiple perspectives and design rationale capture.

This doctoral dissertation in philosophy at Northwestern University considers the two most important philosophers of the modern age. I conducted my research during three years in Germany: at Heidelberg, where Heidegger's work was continued, and at Frankfurt, where critical theory extended Marx' thinking. In recent years, I have applied conceptual and methodological perspectives from Marx and Heidegger to the theory of CSCL. In particular, Marx countered the ideology of individualism by analyzing social structures and interpersonal interactions at different units of analysis than the individual person. Heidegger also questioned the traditional ontology of natural objects with innate attributes by proposing dynamic interactive processes of beings in their ecological context. Today, the philosophies of Marx and Heidegger are still extremely relevant-provided one adapts them to the current socio-historical context and adjusts each to the implicit criticisms of the other.
