I’ve started a second OpenSim project, but I’m still thinking about how I can expand the Undersea Observatory sim. Spending time building this sim has really caused me to consider how worthwhile an endeavor this could be. The vast majority of the ocean depths are completely unexplored, yet it’s all just lurking below us on the same planet. It’s one thing to look at the stars millions of light years away and realize we may never reach them, but it’s taunting to think that the ocean is just right within human grasp, but still mostly uncharted. Allowing students the chance to become deep sea divers, albeit virtual ones, gives them an opportunity few people will ever have.
One thing I’d like to focus on for the sim is the geological aspect, and create tectonic shift simulations and underwater volcano eruptions. It’s really quite beautiful and amazing to watch footage of this sort of thing. Check out the video shown below as an example.
I’d also like to focus more on the realism of such a setting, and create more true-to-life scenarios for the users. I’d like to include scientific tests and experimentation for the students, and add an actual lab to the observatory. In fact, the NOAA has a base in the Florida Keys called the Aquarius Reef Base which I think would be awesome to recreate as a separate scale model. To better accommodate large groups of students, I’ve been considering expanding the sim to four regions, with each region containing a satellite facility with its own unique layout and missions. Then the students could rotate between regions as necessary. Aquarius, or a structure similar to it, would be a perfect satellite laboratory. The Aquarius web site has a good amount of photos, lesson plans, and live webcam feeds during missions containing a lot of good educational material. A lot of these ideas could easily be adapted and incorporated into the overall sim for student information.
Version 0.9 of my Undersea Observatory for OpenSim is available for download. It’s available as a standalone OAR, which can be imported into your own OpenSim server, or another OpenSim host like Kitely. There’s also a standalone version packaged with Sim-on-a-Stick that you can basically just unzip and run. I’ve noticed a few bugs already in the sim, which I’ll fix. The permissions seem to be incorrect for the mini-submarine, so I don’t think visiting avatars can use it. Somehow my install got corrupted, and I can’t even modify the submarines, so I’ll have to figure something out. And I’m still working on scripting the squid and the kiosks, so I removed those from this version. They will be added in the 1.0 release.
I have a poster session exhibit set up at the VWBPE 2012 Conference, too, which is running from March 15-17: http://maps.secondlife.com/secondlife/EduCommons%20Bravo/84/41/26
UPDATE 2012-03-16: My exhibit was nominated for the award for Best Example of Educational Practices in a Virtual World!
OpenSim is making headway as a viable alternative to Second Life. About 98% of the functionality of Second Life is present in OpenSim. The remaining 2% primarily deals with vehicle physics. Although it is still considered “alpha” software, OpenSim hosting is sold, and teachers, students, and businesses are taking advantage. The alpha status reflects more on the rapidly changing nature of the virtual world market, than the stability of the software itself. Microsoft and IBM have some backing in it. Intel operates its ScienceSim experiments with OpenSim, and has made headway in providing models for ubiquitous shareable content and massive user connections.
There are definitely some measures being taken to address educators’ needs. The Jokaydia and 3rd Rock Grids have been around for several years, and they are largely education-oriented. Last year, Firesabre launched its own Starlight Grid, which provides private hosting for educators. And Kitely is starting to establish itself as the premiere third-party choice for educators, and provides the option for making user-created regions private. However, as hypergridding becomes more stable and common, this can be the vehicle to unite different grids into a single education-related hypergrid. The common “education hypergrid” should blend the most relevant content for students and teachers into a singularly accessible virtual space. There should never be any reason for a teacher or student to log out of their viewer and log back into another grid with a whole new avatar. But we need to think about how to make such a hypergrid suitable for students, especially K-12 since there’s often a litany of additional laws and policies governing online interactions and access for them.
A few thoughts and ideas come to mind:
- It is more productive to include students rather than solely use teachers to create content. Many teachers already do this, since with their often beyond-full-time jobs they simply don’t have the time to both learn the skills needed for building in a virtual world, and actually construct the content alone. We should use the skills of the young tech-savvy generation, and develop constructionist class projects that appeal to our students.
- Activities should directly tie in with the curriculum. This is rather obvious, but it would be useful if virtual world activities were tagged with the relevant standards and/or objectives they address. This way, others in the same state, province, or country can find relevant material, without having to wonder if it actually addresses the necessary learning content or is just another topical sim.
- To address safety issues, different approaches have been taken. I mentioned above how FireSabre and Kitely provide private regions. For educators, they don’t want inappropriate content to drift in, or outside trolls to visit the region and cause havoc while students are using it. While securing a sim for exclusive private access is well-intentioned, they miss out on the community-produced educational content. Whether this is on Second Life, OSGrid, or any other virtual world system, a significant strength of the virtual world is in its shared content. We should avoid having to recreate the wheel each time.
- One solution could be to script a session monitor. Those who wish to join the education hypergrid can be required to place a script inside each region which connects to a server and monitors participants. Teachers who wish to use a particular region (or group of regions) for learning but are worried about others coming in and disrupting the class can reserve a session, and either enter their students’ avatar names, or have the students sign up themselves. The script would monitor anyone entering or currently in the region and kick out anyone not registered for the session. A publicly viewable calendar in the regions and on the web would let others know what time slots are open.
- We need to provide a venue for coordinating with educators and organizations who are considering investing actual time or money in the development of a sim. If similar goals and objectives can be identified, pooling resources together may help alleviate the burden for all parties involved.
One solution to the problem of inappropriate content and the ability to provide a safe gateway to Second Life for students 16+ may be to build a custom viewer that uses whitelists. Ideally based on Viewer 2/3 (e.g. Kokua and Firestorm are two viewers being developed off this branch), it would access a server-maintained whitelist of regions appropriate for students. Anything not on the whitelist would not be accessible from the viewer. This can cross over to OpenSim as well. Though some regions on different grids may be “education-appropriate” and suitable to be hyperlinked to, other regions may not be. A mechanism in the viewer could prevent teleporting to regions that aren’t specifically part of the education hypergrid. This doesn’t prevent the usage of other viewers from bypassing these client security measures, but it’s still one measure that could help, and may meet the security policies of many schools and districts. Another option is to implement a teleport-restricting module on the server side so it limits access to educational regions, but since OpenSim is still in alpha, requiring it be included in all upgrades may be inconducive, unless a separate fork of OpenSim is made (much like OSGrid or Diva Distro).
- When appropriate, content should be Creative Commons-licensed. This isn’t entirely necessary, and I believe there is tremendous value in reinforcing the commercial OpenSim goods market. But any CC content could be provided as OARs and IARs (compressed archives of OpenSim content), so it can be installed on private servers. Direct links to OARs and IARs should be posted inside the regions themselves, when possible.
- We should create an open, zero-cost (for the end user) conference region. This can be accessed from anywhere in the hypergrid, and can be reserved for school events or professional development as needed.
Hopefully I’m not too far off base with some of these thoughts. I believe as we move forward it will become increasingly important to standardize how educational simulations are maintained so they can meet the policies and safety standards of most school systems.
