Full HTML Index
20 years at Caltech as a Physics faculty
Particle Data Group member for a while
Dean for Educational Computing at Caltech
worked on experiments E110/260/350 at Fermilab
At Syracuse, I have a joint appointment in Physics and Computer Science and work on
  • Numerical Relativity and earthquake prediction
As well as University teaching, I work mainly in training or lifelong learning fields
NPAC web pages mainly accessed for education including kidsweb(K-12) and my courses in computer science

Foil 4 Some General Remarks

Full HTML Index
What is the "Enterprise" (business) model for science education and indeed universities themselves as an institution?
US has a clear technology leadership in spite of perceived educational problems
  • It imports expertise and exports graduate education very effectively
My physics students rarely end up in physics but do find that physics taught them good problem solving skills.

Foil 5 Technology Opportunities in Education I

From Master Set of WebWisdom Education and Training System: Distributed Objects and Collaboration NSF Workshop -- 3 Dec 97. *
Full HTML Index
Developments in Object Web (Java, CORBA databases etc) will give higher quality basic curricula with glossaries, database backends, reusable objects etc.
  • More modular approach to educational material
Virtual Laboratories for Science -- including computer science (programming)
  • See Phy105/106 Applets, VRML2 as in Visible Human, languages from Fortran to SQL with Web Interfaces
Voice(RealAudio) and Video(H263) capture of teacher as augmentation of lecture curricula material
  • Record when teacher is delivering to capture adrenaline enhancements
Searchable video archives for finding critical few minute length clips to use in class
  • More useful han searching 10,000 movies for "Jaws 7" which makes poor use of digital video

Foil 6 Technology Opportunities in Education II

From Master Set of WebWisdom Education and Training System: Distributed Objects and Collaboration NSF Workshop -- 3 Dec 97. *
Full HTML Index
Collaboration Technology designed to link people, computers and instruments (accelerators, telescopes ..) together
Immersive Virtual Environments using VRML
DoD Modeling and Simulation (generalized flight simulation)
Log accesses using databases and analyse results (data-mining) for assesment
All these technologies can be used synchronously (with teacher) or asynchronously (exploratory learning in students' time)

Foil 7 Some Observations on Education

From Master Set of WebWisdom Education and Training System: Distributed Objects and Collaboration NSF Workshop -- 3 Dec 97. *
Full HTML Index
Technology can improve quality and reduce cost
  • different people have different goals/expectations
Training (typically lifelong learner) and Education communities surprisingly far apart
  • Training tends to have highly motivated learners with difficult time constraints. So asynchronous learning with minimal teacher in the loop is easier here than in education
Surely we need to support both asynchronous and synchronous (teacher in the loop)
  • Note asynchronous supports exploratory learning
  • Good synchronous support collaborative interactivity -- so both models are interactive
At a recent distance education conference, exhibitors show some 20 Web-based asynchronous systems,; only 2 synchronous

Foil 8 Asynchronous and Synchronous Learning

From Master Set of WebWisdom Education and Training System: Distributed Objects and Collaboration NSF Workshop -- 3 Dec 97. *
Full HTML Index
Traditional Education "favors" synchronous style but if you use Web, it is clearly easier to chose asynchronous
  • Need to remove historical biases in learning models
Role of Teacher in synchronous Web based learning system is that of a Tour Guide to a rich (asynchronous) Web Site of material the student can return to
  • In our course at Jackson State, there is 100 megabytes of teacher delivered foils and 150 megabytes of "tutorial material" which are highlighted in synchronous classes
As well as remote "deliverer of lecture", there is a local "mentor" at JSU while in general homework can be set and graded either remotely or on site.
Basic strategy is to support simultaneously asynchronous and synchronous learning

Can now offer addon-on courses with "leading edge" material (Web Technology) which give JSU graduates skills that are important in their career
  • Job fair employers liked Java Programming!
Needs guaranteed 30 (audio) to 100 (two way) kilobits per second bandwidth assuming course material mirrored at JSU
  • Can be offered using CD-ROM's to homes with audio only link and 28.8 kbaud modem

Foil 12 Next Steps in CSC499 Experiment

From Master Set of WebWisdom Education and Training System: Distributed Objects and Collaboration NSF Workshop -- 3 Dec 97. *
Full HTML Index
There are many universities/schools where such "augmentation would be valuable
  • http://www.webwisdom.org happy to offer such courses
Experience with teaching in China suggests huge demand in foreign universities where faculty less up to date in latest material
Will repeat course at JSU next semester with improved curricula and hopefully improved bandwidth
Hope to produce a grade 7-12 version of Web Technologies for kids offered in depth of this winter in Syracuse
Note base material used in about 20 different courses/tutorials over last 2 years
  • This approach has obvious economies of scale
  • material updated continuously (e.g. Java1.0 to 1.1) which requires such economies to be realistic

Foil 23 Basic Object Web Technology Model

From Master Set of WebWisdom Education and Training System: Distributed Objects and Collaboration NSF Workshop -- 3 Dec 97. *
Full HTML Index
The current incoherent but highly creative Web will merge with distributed object technology in a 3-tier client-server-service architecture with Java based combined Web-ORB's
COM(Microsoft) and CORBA(world) are competing cross platform and language object technologies
  • Javabeans plus RMI is 100% Java distributed object technology
Need to abstract entities (Web Pages, simulations) and services as objects with methods(interfaces)
How do we do this while infrastructure still being designed!
One can anticipate this by building systems in terms of Javabeans e.g. develop Web-based databases with Javabeans using standard JDBC (Java Database Connectivity) interfaces

Foil 25 What is an Educational Object?

From Master Set of WebWisdom Education and Training System: Distributed Objects and Collaboration NSF Workshop -- 3 Dec 97. *
Full HTML Index
We have a set of containers -- courses, training modules, degree programs, lectures, online Universities ....
We have a set of base curricula entities
  • This can be defined at various level of granularities. It is probably useful to optimize around a base unit that is a "blackboard full" or "screenfull"
  • This base unit is aggregated into hierarchical containers
  • It is itself made up of smaller objects
There are a set of people (students, teachers, administrators) with properties
There are relationships such as courses taken and grades gotten by students
There are a set of Services and Tools manipulating objects

Full HTML Index
The containers needed in WebWisdom are characterized by classic library metadata (author, institution, licensing, Date, Title, Abstract, parent and children containers etc.)
The people have two classes of data attached to them
  • "Personal Information" Such as Name and SSN
  • "Performance Information" such as grades gotten and courses taken
IMS and ADL have good initial start on this.

HTML Page; PowerPoint presentation; Task in Virtual World as in flight simulation training; Sample Programming examples; Sample Physics Simulations; Voice recordings in foreign language training; Digital Video clip .......
These are "classes not "objects" as for instance a given HTML Page can be used in multiple containers (courses) and have different attributes in each case

Foil 28 What are General Properties of Curricula Objects

From Master Set of WebWisdom Education and Training System: Distributed Objects and Collaboration NSF Workshop -- 3 Dec 97. *
Full HTML Index
Each object has contents which could be embedded document types such as images, bullets ..
Each object has a "Next" and "Previous" object inherited from container
There would be for each display of object, an "up/down" state representing where (e.g. which bullet) teacher or student is
One would attach to object, the audio/video clip of teacher presenting it
There would be as in PowerPoint, "notes" attached to object
Licensing information
There would be log events attached to object used in assessment as well grades and grading method.
Particular curricula objects would inherit general properties but also have special properties which would be different for an HTML page and Physics Simulation Java Applet
