What is Google Wave?

It is an unusual and slightly refreshing feeling to sit in a technical computer presentation have no idea of what the presenter is talking about. The experts from Google Sydney who have developed the technology are giving an introduction for developers on how to use it. While the details of Java and Python APIs and the use of various techniques is familiar and by the end of the day I could probably code a Google Wave application, I am still having difficulty understanding what it is for. There are some glimmerings of understanding happening. One is that Google Wave robots (applications running out in the cloud) can manipulate the Wave data in XHTML format. Also there is an OpenSocial interface coming to allow for interaction with social networking services (or for building social networking services). These are of interest for my intended application in e-learning. This could be used to build web based services for students to interact with each other and the tutors. Even if it does not turn out Google Wave is not the technology for this (or more likely is more technology than needed) it might make a good prototype.

ps: On a less serious note, the first Google Wave presentation was illustrated with images of not very friendly or pretty looking robots. Ruth Ellison, head of WSG Canberra, gave a presentation The Uncanny Valley at BarCamp Canberra with more interesting robots.

Social networking in e-learning tool

At Matthew Allen's online learning seminar in Canberra I speculated about having a way to link e-learning systems easily to external social networking tools. One of the less well known open source e-learning systems, ATutor, claim to have done some of this by implementing the OpenSocial 1.0 standard in a module called "ATutor Social". This is somewhat limited in its features, but shows what may be possible. The Atutor code is open source:

ATutor Social is a social networking module that allows ATutor users to network with each other. They can gather contacts, create a public profile, track network activity, create and join groups, and customize the environment with any of the thousands of OpenSocial gadgets available all over the Web

OpenSocial

ATutor Social is based on the Google OpenSocial standard, implementing the Container part of the standard in ATutor. It essentially turns ATutor into a platform for OpenSocial applications. Applications are based on the Gadget part of the OpenSocial standard, and gadgets plugin to containers. Gadgets are available for a wide range of purposes, from simply linking a quote of the day app into the networking environment, to integrating sites like Flickr, Picasa, and YouTube, as well as integrating other social networks like Facebook and MySpace.

Anyone familiar with iGoogle, can click on "Add stuff" to find a list of gadgets that plug into the iGoogle environment. Gadgets that work with iGoogle (or most of them), also work with ATutor

ATutor Social Features

• Search Network: Search for people on a network to display basic information about them. Login to add people as contacts.

• Privacy: Select from a range of privacy settings to control who sees what parts of your profile, and control which parts of your profile are searchable by others.

Instructors

• Turn off ATutor Social: ATutor Social runs both inside or outside of courses. Instructors may choose to disable social networking in their courses.

Administrators

• ShinDig Location: The ShinDig server acts as a hub for a social network. By default social.atutor.ca acts as the central hub for the ATutor social network. Administrators may choose to point to a different ShinDig server to create a private network.

• Public Source Code: All ATutor Social source code is available for public checkout from the Subversion version control repository.

From: ATutor Social, ATRC, 2009

It is some time since I have looked at Atutor and the development of the package has progressed considerably. Some features of interest are:

1. ACollab: ACollab is a collaboration tool which can be used with Atutor, or on its own. there is a demo for it. Students can use thios to work on group projects, with sdhared document development being the main feature.
2. AChecker: is an addon to test web pages for accessibility using proposed Open Accessibility Checks.
   

3. Release Dates:

   Atutor allos the course designer to set a date when particuarl content will be available to the student. Unfortunately these dates appear tio be absloute calandar dates, not relative to the start of the course (as for example day 1 of week 3 of the coruse).
