Software Development Projects (1990-present)

These are some of the systems I implemented in the past decade, either at the Fraunhofer Institute, the University of Colorado or as a consultant. Except where indicated, I was the primary developer and they resulted in working prototypes. Theoretical frameworks for most of them are presented in my book, Group Cognition. In some cases (e.g., BSCL, Hermes, State the Essence and WebGuide) they are being used in on-going field studies.

VMT (2003-present): Virtual Math Teams is software to support collaborative problem solving of school mathematics by middle school and high school students who visit The Math Forum and join virtual math teams to discuss mathematics together. See: http://mathforum.org/vmt.

BSCL (2001-2003): Basic System for Collaborative Learning is a knowledge-building environment with personal and group perspectives based on BSCW, a web-based shared workspace. Funded by the European Union ITCOLE Project, it is being used in schools in several European countries. See: http://GerryStahl.net/publications/conferences/2002/criwg/Stahl_CRIWG_Paper.doc.

WebGuide (1998-2001): a knowledge-building environment with personal and group perspectives to facilitate collaboration and management of shared information spaces. Tried out in a middle school course and two graduate seminars. Supported by grants listed above. http://www-jime.open.ac.uk/00/stahl/.

InterOp (1999-2000): XML-based software to export data from incompatible knowledge-building environments in a standard format for display using XSL. Also used for client-server connection in WebGuide. Supported by CILT/SRI. http://GerryStahl.net/xml.

State the Essence (1997-1999): educational software using latent semantic analysis (LSA) to provide feedback to students summarizing a text. Used in middle school classrooms for three years and subjected to rigorous controlled experiments showing positive results, particularly for students having trouble understanding the given text. Supported by McDonnell Foundation. http://GerryStahl.net/publications/journals/ile2000/ile.pdf.

SimRocket (1998): a model-rocket simulation used with a middle school project team to analyze the effects of different rocket features. http://GerryStahl.net/publications/conferences/2001/ethnography2001/ethnography.pdf.

WebNet (1996-1997): a Web-based design environment for LAN design and management. Integrated a number of components for collecting, displaying, up-dating and discussing domain knowledge and local knowledge about LAN configuration. Supported by ARPA. http://GerryStahl.net/publications/journals/ai&society/AI&Soc.PDF

CIE (1995-1996): a workplace documentation support system for ISO 9000 certification, using computational perspectives to support bottom-up documentation processes. Prototyped for a local software startup.

Tracker (1995-1996): an information management system for the Baltimore public schools to track services to students on welfare. I worked on interface components to an Access database as a consultant.

OptoNet (1994-1995): a software feedback system in LabView with real-time analog-to-digital data acquisition to stabilize holographic equipment during space flight. This software was tested on NASA zero-g simulation flights. Developed under an NASA SBIR II grant.

TCA (1994-1995): a digital library for teachers to exchange, discuss, and adapt curricular materials for constructivist classrooms. The Teachers’ Curriculum Assistant anticipated approaches now being implemented years later. Prototyped under an NSF SBIR I grant. http://GerryStahl.net/publications/journals/c&e/C&E.PDF

Crew (1993-1995): a case-based reasoning system to model long-term astronaut missions, developed under contract with NASA in cooperation with psychologists at Houston astronaut support. Extends and integrates several AI techniques. Developed under an NASA SBIR II grant and delivered to NASA. http://GerryStahl.net/publications/journals/crew/crew.PDF

Hermes (1992-1993): a hypermedia substrate for design environments, including computational perspectives, persistent versions of drawings, user-programmable critic agents, extensible scripting language. This was my dissertation system to implement an environment for lunar habitat design. NASA subsequently used it for their Space Station Freedom Man-Systems Integration Standards design guidelines for spacecraft. Supported by CASI and Johnson Engineering. http://GerryStahl.net/publications/conferences/1990-1997/cogsci93/COGSC_TR.PDF

Phidias2 (1990-1992): an object-oriented rewrite of a hypermedia substrate for design rationale using contexts. This was an early version of Hermes. Supported by CASI and IBM.

InterView (1990-1991): an information management system for US West service providers to access data in multiple legacy database systems. I worked on C++ interface components to an object-oriented database management system as an intern.
