Abstract

Currently, e-learning web sites are used by student individually. Teachers prepare some

learning materials including exercises or homework and post them on the web pages.

Students will interact directly with the learning materials through completing a sequence of

programmed exercises. There are many e-learning web sites that are provided with excellent

contents and designs but they generally lack of interactive response and face-to-face

communication. Students cannot ask questions and get response immediately. It is just like

one way communication for learning. Therefore, it yields student’s boring and quit before

finish the course. Many students find that their learning is most effective when they actively

construct knowledge during group social interaction and collaboration. In this paper, we

propose inspire creativity of e-learning called Classroom on the Internet by using RTMP

[4]. RTMP (Real-Time Messaging Protocol) is a sophisticated TCP-based real-time

networking protocol which supports the efficient exchange of messages, synchronized data,

audio, and video. Teacher and students can publish streaming audio, video and other data

messages to present streaming media with interaction or navigation. We apply this protocol

with remote SharedObjects [4] technique which allows multiple connected users to share

data and user interfaces in real time, coupled with client and server data storage capabilities.

Using this classroom on the internet, students can immediately interact with teachers as

though they are studying in real classroom. We believe that it will be interesting place for

teachers and students to join and become the most important feature of e-learning web sites

that makes more attractive and complete e-learning system. In the future, it will further be

implemented as virtual school or university on the internet.

1. Introduction

Technologies such as streaming video, virtual learning environments and teleported

experiments are entering the Web-based learning arena. Along with the development of a

second-generation online education infrastructure, it will be necessary to consider changing

the interface of education such as reinventing pedagogy for the new interface, including

multimedia and hypermedia enhancements, and creating the educational standards necessary

for generalized deployment. Instructional learning goals should drive media selection,

application, and the course development process. Characteristics of the distance learner and

the impact of technology are also important considerations in instructional media selection

and course development. The new streaming technologies have made it easier than ever for

people to receive a quality education by bringing the classroom to the student. Imagine, a

teacher at one university campus delivering a lecture while students in a classroom two

cities away watch the same lecture in real time. In a residence hall not far away, a student

recovering from an operation watches a lecture recorded from an earlier class she had
