1.1. Introduction

Interactive Remote Instruction for heterogeneous environments
(IRI-h) is a Java based system to enable "Active Learning
" over the Internet. Students and a Teacher participate in
a class by running the IRI-h client software on their computers
connected to the Internet. Thus the computer becomes the window
to a virtual classroom for each participant. The " H"
in the acronym stands for various meanings of "heterogeneity".
IRI-h works for both PC and Unix platforms as well as for heterogeneous
network environments such as client at a host that can not be
reached through multicast or that has bandwidth limitations or
shows long round-trip delays. |
