| This master foilset has extra foils for two Web Training Presentations in San Diego DoD Modernization Users Meeting Session on Internet Based Training |
| One was Experiences with WebWisdom and one was on Future and Key Features of WebWisdom |

| This discusses architecture of proposed WebWisdom electronic education and training system which is designed for both distance and local applications |
| We describe experiences that were put into design of WebWisdom |
| We discuss particular features including core database, administration, collaboration, disabled interfaces, digital video , VRML and Geographical Information Systems |

| NewsBank (CD-ROM originally) for K-12 |
| Search a specific Domain -- e.g. NPAC Web Site |
| Parallel Oracle host for Usenet News Groups |
| Secure Database for Document System |
| CareWeb Patient Record Database |
| Carrier's Home Page has NPAC built Oracle core for product information |
| Language Connect University has NPAC Startup Translet Oracle core for administration |

| Information can be presented in formats that best fit current state of display technology from Netscape 1.1 HTML to JavaBean White Board |
| Can track such changes in Web technology! |
| Can use database to support search of material |
| Makes support of "play-lists" particularly easy as these are just selected out of separate tables in database (if one table is one foilset say) |
| Same database can be used in other functions such as administration |

Although we have 384 foilsets imported to the Web -- this is not the correct way of doing it!
|
| Originally we thought a "Web Foil" is an enhanced HTML and we built a prototype using HotJava |
However now believe this is not powerful and correct Web implementation of "foils" is a JavaBean stored as a serialized Java Object
|

| Start with a full drawing program supporting "art" and importing of images where basic entities are Java objects |
| Start with system integrated with Tango |
| Basic Unit is a "foil" -- typically NOT scrolled (but supporting this) |
| Foils are arranged into foilsets dynamically as in current WebWisdom and allow notes(addons) etc. |
Import existing PowerPoint/Persuasion from "outline" text with automatic font size scaling
|
| Allow user to add highlighting and images "cut" from original screendump of PC foil |

VRML has been motivated by virtual environments which may be very important
|
However one focussed application is to "virtual field-trip" in our K-12 Living SchoolBook where we have a VRML front end to 3D GIS (Geographical Information System).
|
| Can also use VRML to display results of 3D simulations such as weather predictions |

| Video as used in teaching is typically not complete 90 minute movies but short focussed segments of a few minutes |
So text indexed NPAC technology very appropriate in education

WebWisdom.org domain will be an electronic virtual University starting with current NPAC curricula but not restricted to this
|
| WebWisdom.com is a spin-off from NPAC to develop production versions of our collaboration, video-on-demand, education and GIS technology |

| Our current approach was based on many experiments in electronic delivery of course material |
| We describe some of what we did and what we learnt! |
| General WebWisdom Framework |
| Scope of teaching and re-use from Syracuse to China -- Undergraduate, Graduate and Continuing Education |
| What is a foil? Natural Unit of presented Information so computer screen == overhead projector |
| Current WebWisdom converts legacy systems with hierarchical data management and display |
| Some integrated services including audio and logging |
| We describe WebWisdom's many Programming laboratories |
Full HTML Index
| WebWisdom is our System at NPAC built from PERL and JavaScript and features |
| Built-in Audio dissemination and recording |
| Multiple Foil formats (e.g. frames/noframes) controlled by user templates |
| Hierarchically Arranged Information |
| Parameterized (e.g. font sizes etc.) HTML |
| Automatic Logging of pages accessed |
| Database search of material |

We have (June 23 1997) in a uniform intermediate format 384 foilsets and 15810 foils coming from
|
These are either "basic" or selected via a play list from basic foilsets
|

| Typically presenters don't like scrolling while talking and so best to dynamically (statically) size information to fit on a single overhead or a single computer screen |
Foils have attached to them
|
| So cannot attach foils to audio/video stream except for a fixed foilset -- must cut up audio and link to individual foil |

We have used Web technology to allow extensive re-use of material -- especially for our Web courses which are rather more popular than HPCC!

Graduate, Undergraduate, Certificate (continuing education), China (in English), China (in Chinese)

Current WebWisdom timestamps and logs all URL's visited
|
| Note find I often change "foil" at wrong time as I flip but then realize had more to say on previous "foil" |
| This and other glitches (see later) imply need non trivial Real Audio editor built from their tools |
Full HTML Index
Usually preserve Real Audio as a scripted foilset as typically do not discuss every foil in class -- I jump around and certainly don't finish a given topic
|
| Also record off line in my office and these are typically associated with "base foilset" and inherited by virtual foilsets generated from it! |
Note what I say in office (no live students) tends to be less "innovative" than what I say in live lectures

Server goes down due to computer or network problem
|
Client goes down due to JavaScript/Netscape crashes, SGI runs out of swap space etc
|
Audio Quality variable for reasons that could be as mundane as mike positioning or battery charge
|
I get confused and say the wrong thing or change what I am doing!

We teach Perl Java JavaScript SQL PL/SQL HPF Fortran90 and MPI
|
HPF Fortran90 and MPI are hardest as need special Web Integration
|
| Other languages are easier to teach because the are more or less Web ready but require some modest technology to properly show students program, data and results |
Traditional central displays difficult as often need to "scroll" to see details of a nontrivial program
