Opensim Guide for Schools

David W. Deeds has created a much needed guide to setting up OpenSimulator in your school. It's more than a step-by-step, including some discussion of the reasons for using virtual worlds in education. Here is the Scribd version (cool, that worked), or you can download a copy from his website. I've only just skimmed it but it looks great, explaining many of the complications one encounters in configuration and setup, as well as covering the options pretty well. IMHO the Diva setup could have been promoted more heavily as I think it's more user-friendly than the main release, since it includes documentation and update utilities. But it also uses MySQL as a default for storage rather than SQLite and he may have thought setting up a db would pose too great a challenge for the average user. Great service he's done, putting this together!

OpenSimulator: School Quick Start Guide

Learning with Gestures

A sneak peek at Windows 8 reveals that Microsoft wants to integrate its os with tablet hardware to keep up with the huge growth in people's desire for the gestural UI of tablet devices. This should be a much bigger post because there are so many issues this transformation raises for schools but all I can come up with right now is a list of problems to think about and questions:

• How does learning through apps restrict learning possibilities and how does it facilitate new learning possibilities?
• Microsoft seems to be trying to simplify the user experience while still providing access to the file system (explorer.exe still exists!) but iOS removes a layer of user control in that sense. What happens to the learner when this level of control is taken away? Granted, file systems are simply TMI to many users, but if you know what you are looking for and aren't allowed access to it that takes away an important level of control over your machine.
• The rush to gestural UI is happening so fast. My feeling is we're being led into making significant decisions about how best to provide and use technology by consumer preferences. It's way too early to say learning with apps is more effective than learning with software on a more open and transparent os. Of course, both can be effective, but it all comes down to how they are used, and there's still so much to learn about that.

Much more to say, but it will have to come in future posts...

What Do Girls Want to Do With HTML?

I recently spent a few classes taking my 6th graders on an HTML crash course. I only intended to spend one or two classes on it but they couldn't get enough! It was interesting to see what really got them excited and what the majority of them didn't really care much for. I put together a couple handouts they could follow at their own pace so as the classes went on you started to see the pages become very original creative projects. Here are links to the handouts:

• HTML part I (docx) (pdf)
• HTML part II (docx) (pdf)

Part I covers text formatting using HTML tags only, no CSS, including font color and font face, heading tags, paragraph tag, block level alignment, and the image tag.

Part II gets more interesting with hyperlinks, fun and simple tricks with JavaScript, like alerts and buttons to change the background color, and finally using the embed and iframe tags to put videos, audio, and other web pages in your web page.
So while a few girls really got into the JavaScript and hyperlinks, what really went viral was the possibility of embedding videos and putting up images they made on some I HEART website using all their friends' names. So for the majority I would say it became a mini social network right there on our school network where they shared videos, photos, and shout-outs with each other. Pretty cool. I was having them save their pages on a network drive and with two other 6th grade classes doing the same project at the same time the pages themselves almost became a kind of social network, since they knew how to navigate to the network folder and see the other pages. Now I'm wishing I had taught them how to hyperlink to each others' pages! That would really have been a social network.

Understanding Photoshop Documents

I find that my students often have a superficial understanding of aspects of how computers work that persists even after they've been explained. For example, after giving instructions to 7th graders recently to save cropped screenshots they were taking as jpegs to upload to voicethread, I saw one student navigate to her psd file in Windows Explorer and simply change the file extension from psd to jpeg. No, that won't work! I've been doing a lot of research lately about the need to provide visual representations of concepts, especially for girls, who tend to process information in the language areas of the brain rather than the spatial areas. I left it free of text so people can make their own points with the visuals. The main points are layered information vs. compressed "flat" information, Photoshop-specific platform vs. universal program platform, and large vs. small file size.

Technology Connecting People

• 5th graders together in the Mars sim 
• one pair of students Skyped in to the class from a different part of the building because one has a broken ankle and can't go up the stairs
• remote pair also logged into the Mars sim, where the rest of the class can see their astronaut and chat with them
• technology bringing people together! 

Peaceful Moment On Mars

Our Mars simulation was a big success this week. With the technical glitches and hurdles smoothed out, the students and I could focus on the uniqueness of the experience and enjoy it. At one moment I noticed a team of students had walked their astronaut away from the meteorite field where the other astronauts were gathered and ventured up the crater's side a ways. As they turned around to look over the scene below the screen held a beautifully captured moment with the expanse framed by the crevice in which the astronaut stood. I popped in and got a snapshot on their computer. It's worth looking at the larger version to see the tiny astronauts below.

Second Annual Mars Sim Journey

 A year ago our school took a giant step for 5th grade girls by sending them into our OpenSimulator Mars crater sim to find meteorite samples and enjoy the low-gravity orange haze of the red planet. That first experience is documented here. This week the same science teacher and I are once again introducing our current 5th graders to the experience and I'm happy to say I've learned from my previous mistakes and made some valuable improvements. Disabling flying and showing the students how to use the mini-map allowed them to stay focused on the goal of working as a team and getting everyone through the mission together, which is really what the experience is about. The other technique they took much greater advantage of is local chat. I wish I had the logs because they reflect so much collaborative problem solving and cooperative negotiation. The one other improvement I made was to specify a different account for each pair of students right on the tutorial handouts I gave them, which prevented the duplicate logins that caused groups to kick each other out of the sim repeatedly last year and had me pulling my hair out until I figured it out. These changes greatly reduced the tendency toward chaos that took over at times last year and undermined the simulation experience. So the result has been that they really get the experience and what it's about. It's a really fun way to practice working as a team and solving complex problems. And hopefully we've captured their imaginations about the world of space flight to boot.

All Things Great and Small

The hall of small. The hall
itself was designed and built by a
student!

I wrote about kids imagining things so small they can't see when I started this project with my 7th grade students, wondering why it was that some of them created 2D models in a 3D environment. I still don't have an answer to that question, but I'm certain that all of the students learned a lot from this no matter how they ended up visualizing the microscopic things they were studying in science class. Their work is beautiful. They loved creating bright, shiny things and I think the images they conjured from the building tools will stay with them for a lifetime, like Ener's experience making a cell with epoxy resin and paper clips!
There were tears along the way in this project. While some students settled happily into the world of possibilities in the edit panel and prim handles, others were overwhelmed and made careless mistakes, sometimes deleting their work without a clue how they had done so. You can bet that helped them slow down. They came out stronger for the experience. Just today a student jumped up and shouted out so happy she'd figured out how to successfully edit a script without my help.
It took me a while to figure out the exact workflow of this project, but I settled on 1) having them build in open space somewhere outside the exhibit hall, 2) teaching them how to link their prims and take them into their inventory, 3) rezzing their models in the exhibit hall and resizing them to an appropriate size (some started out huge!), 4) receiving a script from a script-giver I made (script me!) that makes hover text with or without rotation on touch (they edited the strings and hover text color) and putting that into their models, and, 5) adding an open URL button near their models that gives people more information about their topic.
That was all a lot to chew on for 7th graders. There were many steps to follow and I found it helpful to make printed tutorials for the major steps. I figured out a good solution for the script givers. At first they were running the scripts to be given when touched, which was confusing. I finally figured out I could uncheck run to stop them from running when they were given.

The students had to experiment. Their
favorite shape seems to be the torus.

Paving the Road To Digital Success

7th graders are creating 3D cell models with an interface
they've never seen before. 

I imagine it would be an exciting time to be a kid learning to use computers thes days. There are so many computing environments that make so many things possible there are new cool surprises around every corner. But from an educator's perspective this poses a tough problem. How can they develop a solid foundation in all of these important tools? Video editing, image editing, web publishing, collaborative document editing, non-collaborative document editing, physical computing, digital game creation, programming...okay, I'm dizzy. Obviously they can't. Ten years ago an instructor in a web design class I was taking warned us against becoming a 'tool monkey' by specializing in one  program in a domain like web graphics or HTML rather than understanding how any program in a domain has to work and figuring it out when you need it. I don't think anyone needs to be told that now. There are places in the world for Dreamweaver or PHP gurus but not that many. For the power user or anyone who gets under the hood of hardware and software technology has always been what Rand Spiro calls an ill-structured domain, but the ubiquity of apps, platforms, and insinuations of technology into so many areas of our lives now forces the average user to contend with some very complex user experiences. 


As a technology instructor this problem is always foremost in my mind when I design new lessons and units. I want to strike a balance between telling students enough to feel comfortable with something and challenging them to relate what they know to figure out a new situation and test out their own theories. Sometimes I have to reteach things because I've thrown too much at them with too little scaffolding and the class has gone haywire with requests for help. 

Aside from appropriate scaffolding I've been working on making sure that whatever new topics students learn are placed in a meaningful context so they have some compelling reason to be learning a confusing, complex subject. Recently I had my 9th grade robotics students learning to calibrate the four types of sensors we'll be using for our next project (photocell, ir reflective, distance, and a temperature sensor I hacked together). They went haywire and had much frustration, sometimes saying things like "I don't get what we're doing at all." That's a sign something isn't making sense, right? So for the next class I put together a worksheet and emphasized the main purpose of sensors. "Sensors are the robot's ONLY way to know anything about its environment. Without them it exists in a dark, silent, empty world." That conjured an intense image for the students and while they still found it challenging to get it to work they enjoyed investigating the sensor readings much more.

Amazing Building Communities Workshop

Futuristic buses in Beijing

Working In-World

We just wrapped up an amazing four-day workshop on design and engineering of public spaces. Each year we spend this week after winter break teaching special collaborative courses with multi-age groups of students so I worked with a math teacher, a science teacher, and another technology coordinator to put together a series of amazing field trips and a design and building project in OpenSim with nine students in 9 - 12th grades. Our field trips were unbelievable, starting at the MOMA with Design and the Modern Kitchen and Design Over Time, then to the Smithsonian Cooper-Hewitt National Design Museum's Why Design Now? exhibit and a workshop, and finally into what felt like the center of the Earth with a tour of the NY Metropolitan Transit Authority's excavation of the planned 2nd Ave. subway tunnel. (More amazing info and pictures of that here!)

Working RL

Renewable Energy Community

Interspersed with those experiences was our project using OpenSim to design and build communities. The students broke into groups,  picked a location in the world to design for, and researched the needs, cultures, and geography of the local region. Once they had chosen their places I created approximate heightmaps and imported them to adjacent regions. I had hoped to use Virtual White's steps to importing USGS Seamless Server data to OpenSim but I couldn't find anything similar for international GIS data. So I did some quick brush work and came up with some okay approximations, though way off scale. The areas they chose were Syndey Harbor, Fengtai in Beijing, and an area modeled after Table Mountain near Capetown, South Africa, though the actual Table Mountain is a nature reserve. Each group focused on different aspects of their communities. The Beijing group worked primarily on a transportation center with a station and a futuristic bus. I got them started with a script to move the bus with passengers inside that they obsessively refined to suit different transportation objectives.

Sydney Harbour Bridge

Syndey Harbor Heightmap

The Table Mountain group focused on a community supported by renewable energy resources. They chose their location because of the high winds in the area and integrated purple wind turbines inspired by Ener Hax's amazing work and solar panels on light-filled structures. And the Sydney Harbour group worked really hard on a fantastic replica of the actual bridge complete with a waving flag and built an extensive housing complex. They had fun inhabiting the city with some pretty awesome kangaroos they built, though I doubt those are roaming as freely as they would like to imagine.

Aside from Ener's work, we looked at an amazing video of Encitra's model for integrating a podcar system in Uppsala, Sweden. And we took a virtual tour of some Second Life regions, like Ijinle 1796, a composite Yoruba village in Africa Illuminated, the impressive Edmonton Civic Center build, and a nice Chinatown build called Chukagai in Yokohama. I don't know how to do SLURLs but if you search in SL you should be able to find these locations. And we read and discussed some passages about affordances and affective elements of design from Donald Norman's books, The Design of Everyday Things, and Emotional Design.

I was so impressed that they really got some essential concepts about what it means to design things for people. On one of our field trips the guide asked them some questions about design and they said things like, "You design things to solve particular problems," "Your first design will never work," and "At some point you will have to use math to get your design to work right." I was so proud of them!

A bit of fun on the bridge

What else can I say....It is so rewarding to work in a way that allows for learning from such different angles, gives them such great latitude for creativity, ingenuity, and collaboration, and provides a social element that really makes it fun. At some points we all feel like it's a game that we're playing together but there's enough freedom to set goals together and for the students to set and revise their own goals. There are even a few girls who want to continue working and create a replica of our school building in the sim! It's also the kind of work that is tremendously engrossing and the concentration is exhausting. They liked working steadily on something and then sitting back and realizing how tired they were from concentrating so hard. In all, what an amazing experience. I look forward to next year's Winterim class.
