1) Problem of knowledge in health care
• Globalization• Environmental quality• Working conditions• Poverty• Literacy• New technologies for
– prevention, diagnosis, & treatment– for information and communication

Research versus practice
• Knowledge vs. application• Science vs. ordinary knowledge• Producer vs. consumer• Technology developer vs. user• Knowledge as output vs. knowledge as
input

2) New information and communication technologies
Think of it [Mosaic] as a map to the buried treasures of the Information Age. / A new software program available free to companies and individuals is helping even novice computer users find their way around the global Internet / … an applications program so different and so obviously useful that it can create a new industry from scratch. --Dec. 8, 1993, John Markoff, New York Times

3) Knowledge transfer models
Repository =>
Dissemination =>
Inquiry (knowledge construction)

“Spiritual health plan”
For the Create section --
I would like to accomplish the following goals: Once each week I would like to take at least four (4) hours of the weekend for my own enjoyment. This will include, but is not limited to, things like: going to the beauty shop, going out to dinner or to the movies with my husband, reading my Bible or some other book, or just praying or meditating. … I also will let my family know that I love and support them...

Active participation
No matter how ignorant a person is, there is one thing he knows better than anybody else, and that is where the shoes pinch on his own feet....every individual must be consulted in such a way, actively not passively, that he himself becomes part of the process of authority…that his needs and wants have a chance to …count in determining social policy. .
--Dewey, Democracy & Education
![Page 30: Web Technology in the 21st Century](https://reader030.fdocuments.in/reader030/viewer/2022032415/56813451550346895d9b36b5/html5/thumbnails/30.jpg)
Participatory inquiry
aims to respond to human needs by democratic processes. Through creation of content, contributions to interactive elements, and incorporation into practice, users are not merely recipients of technology, but participate actively in its ongoing development.

Conclusions
• provision of health information => active, two-way, co-construction of knowledge
• citizens use technologies to develop healthy communities
• new literacy skills develop along through meaningful problem solving
• community inquiry provides a framework for democratic change
