Leadership Changes at Linden Lab
Dec 11th
I typically try to pace myself at about one post per day, and I usually don’t focus on news and current events related to Second Life. However, the news of Cory Ondrejka’s – Chief Technology Officer and lead engineer – departure from Second Life potentially holds a great deal of importance for the entire SL community, including the education community.
My thread of discovery followed this path . . .
- CNET: Upheaval at Linden Lab
- Massively blog: Was Cory Linden fired, or did he quit?
- Massively blog: Phillip Rosedale responds to Cory Ondrejka’s departure
- Massively blog: Cory Ondrejka’s departure in his own words
In short, Rosedale and Ondrejka do not share a common vision for the future of Linden Lab and Second Life, so Rosedale decided it was time they part ways. The first Massively post references Rosedale’s recent publication of a new mission statement for SL and subtly suggests it may be a source of conflict between the two executives.
This has specific, direct implications regarding the viability of Second Life over the long term. I’ve seen the Linden Lab leadership questioned in the past (wish I could find the specific article) as a reason why the long term viability of SL may be suspect. This sort of change in leadership presents an opportunity and significant risk.
I’ll continue to follow this story with interest and will be sharing the articles or publications I’m reading via Twitter and my Shared_SLED news feed.

Loading ...Learning & Assessment in Second Life – A Scenario
Dec 10th
In a July post, I wrote about Assessing Learner Performance in Second Life. Jumping there and coming back may be useful. In short however, I suggested that Second Life (or any multi-user virtual environment) makes it more critical that we evaluate the “artifacts and performance produced” by learner experience in Second Life rather than relying on traditional forms of assessment which are designed to approximate actual performance. I did not, however, begin to explain a manner by which that may be accomplished, so the question is, “How do I begin to develop more authentic assessment of learner performance in Second Life?”
The first question to ask is, “What particular task can learners perform or what products can they produce within Second Life to demonstrate they have acquired particular skills or knowledge to be learned within the course?” An example . . . I teach an “Introduction to Computers” course in a community college; IF I were to use Second Life in that environment, I could ask learners – as a class or as a small group – to collaboratively build or explore a large, room sized , walk-in model of a PC computer. That assignment would focus on learner understanding of basic hardware.
A couple of caveats to consider when initially identifying a project, and these relate back to definitions I’ve offered previously of quality instructional uses of Second Life. The “build or explore . . . the walk-in model” is a critical choice. First, if they simply explore a model which I’ve constructed, I need to be sure to include interactive elements that make engaging the content within Second Life uniquely valuable. Otherwise, learners may be able to get the same level of understanding from less intricate technologies – web or print, text or graphics – and that’s not consistent with the suggestion I’ve made that learners should engage content “in a manner not possible through a physical or standard web-based learning environment.” Second, if I require learners to build their own model, I may be introducing skill and knowledge requirements beyond the scope of the course or objective. Learners could very easily spend more time fighting with the Second Life interface than they do on-point with the content for the course; this does not “maintain proper focus on the desired learning outcomes.”
The second question to ask is, “Based upon learner performance of a task or production of content, how do I know they’ve acquired the necessary skills or knowledge required by the course?” One choice is to ask learners to complete a written assessment, perhaps an objective exam of some sort. However, if I have the opportunity to measure actual, “real world” performance, should I not do that rather than approximating learner capabilities using less direct methods?
Back to my walk-in model of a PC . . . I can actually observe learners interacting with the model – either directly by synchronous presence or indirectly via tools I’ve developed to record their interactions with the devices/parts. Setting aside the task of creating the necessary tools in SL, the pedagogical task for me becomes identifying the different levels of performance learners may exhibit. Exactly what sort of interaction with the model constitutes “expert” level knowledge of PC parts and functions? What’s the difference between that and “average/sufficient” level of knowledge? And, finally, what sort of behavior with the device demonstrates that the learner has insufficient or poor understanding of PC hardware?
In short, I develop a list of criteria or objectives which my learners must meet, and then for each, I work to identify three different levels of performance to which point values may be assigned for grading performances. The end result is a performance rubric or matrix.
I think this type of assessment in Second Life is imperative. Transitioning different types of objective assessment tools to Second Life – quiz tools etc – is not a valuable exercise. It’s imposing a philosophically inconsistent method of assessment on the Second Life learning environment in a manner which turns the concepts of reliability and validity backwards. The ability for learners to engage authentic learning through virtual “performance” in Second Life should exclude traditional forms of assessment. Using those forms of assessment in Second Life is a sign of laziness or lack of awareness regarding more appropriate assessment tools and methods.

Dec 9th
It’s been about 2.5 to 3 years since I first rezzed an avatar in Second Life; however, I didn’t “get it” at first. It didn’t help that SL was mostly empty and the build tools just didn’t click with me. Plus, since I imagine I was looking for something specifically to do, that first experience ended with “Now what?!?!” and then vanished into the deep, dark corners of my mind once the one month trial ended (before free accounts were available).
About 14 months ago – soon after I heard about the free accounts – I re-entered SL thinking there was some sort of potential in regards to education even though I still did not understand what SL was or could be. Then, around December 1 last year, the proverbial light came on, and I began to understand what Second Life could and would mean to the education sector. So, after two avatars whose names I no longer remember, Topher Zwiers first rezzed on 12/10/2006.
Second Life also prompted my entry into the blogosphere. MUVE Forward will reach the end of its first year on January 4.

Dec 9th
The sidebar should not be overlooked on this site.
A quick blogger-related post . . . I noticed in feedburner statistics for the last 30 days that less than 3% of visitors to the site are at a resolution lower than 1024 x 768. Given that information, I decided to tweak the template a bit and explore the blogger layout interface a bit more. Why blogger doesn’t make it possible to select a resolution higher than 800 x 600 and then from templates that fit that higher resolution, I don’t know.
However, with some knowledge of CSS and HTML, I dug into the code for the template, which to this point had been developed entirely by blogger’s drag and drop interface. It wasn’t terribly difficult to insert additional sidebar boxes and move widgets around some. Tinkering for an about an hour or so enabled the current, wider template; along the way, I figured out how to create a three-column layout using the higher resolution. I was able to accomplish getting some features in the sidebar nearer the top of the site with a three column layout: previous posts, label cloud, and blog roll specifically. However, the three column layout placed too much emphasis on the sidebars, so I reverted back to two columns using the wider format.
The sidebar does contain resyndicated news stories relevant to Second Life in General and Second Life & Education that I’ve tagged while reading the ridiculous number of RSS feeds to which I’m subscribed via Google Reader. Honestly, there’s as much information in those feeds as there’s likely to be in the posts themselves ;-)
If anyone’s interested in the necessary modifications to create a three column layout in blogger, get in touch. I don’t mind helping out as much as I can.

Dec 7th
As this blog comes up on, in the next 2-3 weeks, the end of its first year, I looked back at one of the early posts, and I’m still blown away by the live music in Second Life. The first live music event I attended – by Louis Volare (RL: Louis Landon) – was the first real hook for me into Second Life. Nearly a year later, Louis still performs on a regular basis in Second Life.

Dec 6th
Stuart Dredge at Tech Digest compiled a list of “20 trends and ideas [he] picked up” at the Virtual Worlds Forum Europe conference held recently in London. Reading that list, I believe several are particularly important to educators working in Second Life.
Trend/Issue 1. Shedloads of virtual worlds will be launched in 2008.
Trend/Issue 2. Teen-focused virtual worlds are huge.
Trend/Issue 19. Is Second Life going to stay a niche?
I think these are relevant to education as a combination. The number and variety of virtual worlds will most definitely grow, and 2008 could see a relative explosion in different MUVE’s populating the landscape. This could bring into the market a viable competitor to Second Life; that doesn’t justify bailing on Second Life, it still has specific benefits for educators, but educators should remain open to trying different platforms. And, as virtual environments grow, so does the adoption rate by younger users. Dredge even comments:
It’s my big takeaway from the conference: the sheer size and popularity of virtual worlds like Club Penguin, Webkinz and Habbo Hotel. Us geeks talk about Second Life like it’s the be-all and end-all of virtuality, but the kiddyworlds have way more active users. More importantly, a whole generation of children are growing up with the sense that virtual worlds are just a part of their lives.
This is an argument I’ve made before as one that makes educational exploration and use of virtual worlds an imperative.
Trend/Issue 5. There will be big growth in corporate use of virtual worlds. Companies holding meetings in Second Life . . . Training for staff . . . although it takes a fairly big leap of faith by a company to get its employees used to virtuality, it’s happening . . . one of the more common criticisms of these spaces – ‘What do you actually DO?’ . . . what you do is improve productivity and save money.
While it takes more time and investment to prepare for the use of Second Life with a live learning environment and learners, I believe it’s more immediately possible for educational institutions to fall in line with this trend: use virtual worlds to conduct virtual meetings and professional development opportunities. In addition to saving time and money on local travel between campuses (where relevant), business use of Second Life within an educational institution may, at the very least, support the learning curve necessary to support the instructional uses of the environment. At the very most? I imagine educational institutions could potentially find Second Life development resources in unlikely, internal places (i.e. imagine an Office Manager attending a meeting in SL to record minutes – only to become interested in and developing the skills necessary to build resources).
Trend/Issue 9. Is it an online game or a virtual world, or both?
Dredge talks about the distinction between online games and virtual worlds – which do not have predefined rules, objectives and outcomes. The trend may be blurring between the two, rather than drawing distinctions, as virtual worlds begin to include more games; he uses the CSI:NY Second Life project as a case on point. I think this potential trend will be important to education in several ways. First, designing and developing learning experiences within virtual worlds already presents new issues for faculty and instructional designers accustomed to more traditional instructional design models (discussed here). With increased blurring between games and open virtual environments will put more pressure on those designing and developing instruction. Second is the potential on the other side of that coin; as we, as an educational community, become more accustomed to virtual environments, we’ll be more capable of designing effective games that engage learners in new and meaningful ways. Third, our learners will face more distractions, as if there weren’t already enough within Second Life.
Trend/Issue 11. Interoperability is important.
I’ve also discussed this previously as one of the primary reasons (second in the list from that blog entry) why educational institutions should engage Second Life.
Trend/Issue 13. Virtual worlds need to become easier to use.
This is certainly true within education K-20. It becomes a feasibility issue within a learning environment. Time and again, we hear about the issues educators face when it comes to orienting a number of learners in a class to use Second Life. JS Vavoom mentioned a several hour learning curve when training his nursing/health science learners in preparation to use the NESIM simulation. I think this issue being discussed at the Virtual Worlds Forum signifies a burden that educators should engage collaboratively; there are many issues common to all learners first engaging Second Life. The solution is a collaboratively developed and freely available orientation area to be shared among educators. The New Media Consortium has the orientation island for educators; the education community needs a similar environment for learners available as a freely available copy/mod package.

Dec 2nd
I attended a SL Community College group meeting late this afternoon. The focus of the meeting was a demonstration of the NESIM nursing education simulation. I’ve blogged about NESIM before, but the demonstration provided a much better, first-hand experience. I tried posting the details via BlogHUD, but I’m not certain it worked terribly well: I believe it truncated the end of the post which was relatively long. Also, I wanted to post the pictures I took. The NESIM is truly amazing work and a fantastic application of Second Life – pictures are necessary to convey the capabilities.
The meeting was well attended by a group of about 15-20 community college educators; we all teleported to NEWG for a demonstration by JS Vavoom (RL: Jon Miller). The Emergency Room Simulator he demonstrated was based on industry standard simulations: METI and Laerdal. Below, I’ve copied details from the notecard and my attempted BlogHUD post regarding the demonstration:
Jon indicates that it’s a few hours of learning curve for SL engagement. Orientation of 54 learners to Second Life was a challenge. Interesting thing – they’ve “given Lindens to students” in addition to the orientation matierals.
Once the patient lies on the table, the monitors turn on. Instructor and student have control over the system via the HUDs – patient/instructor and nurse/learner.
With the patient on the table, Jon increased the oxygen via the tank. In this simulation, the patient reported and pointed to chest pains; as the instructor, Jon changed the heart rhythm, and as the student, he started an IV, administered a lidocaine injection and started a lidocaine drip which was reported in the chat line. Jon then created a medical emergency via the instructor HUD: the blood pressure dropped, the pulse stopped, O2 levels dropped and the ECG rhythm changed dramatically. Jon demonstrated bagging the patient and turned up the O2 rate. CPR compressions were followed by defibrillation – for which specific settings were added (360 Joules). The patient returned to sinus rhythm.
The simulation – patient responses to learner/nurse actions – is mostly controlled by the instructor; at some later point, there will be scenarios scripted with automated responses. With the two HUDs controlling the simulation, it becomes possible to have roleplay as well. All chat and actions can/are recorded for review and study.

Dec 1st
In the YouTube video below,
Dr. Tony O’Driscoll describes the 7 Sensibilities that differentiate virtual social worlds from other interactive media and makes the argument that these sensibilities provide us with unprecedented freedom to create true experential learning opportunities.
I believe this ten minute video presents an excellent introduction to Second Life by focusing on the unique capabilities of the virtual environment.
To summarize briefly:
- Sense of Self is the unique capability of virtual worlds to enhance the development of salient identities, particularly in comparison to the 2D/textual web.
- Death of Distance. Virtual distance is only virtual; distance becomes conceptual only; it’s no longer real and no longer an impediment to interaction among individuals. Dr. O’Driscoll demonstrates the teleport capabilities.
- Power of Presence. With the Sense of Self and the Death of Distance, it becomes possible to project a distinctive presence within virtual space. A short video clip of an in world music concert highlights this sensibility.
- Sense of Space & Perception. Virtual worlds can be molded and created with much less limitation than the physical world. That allows a great deal of freedom. A short video clip of Joe Miller’s Molecule Maker demonstrates how virtual worlds can be used.
- Capability to Co-Create. Jimmy Wales of Wikipedia describes creative co-production, and 3D worlds take us to the next level of co-creation. Architectural students collaborate in a high speed video to co-create a dwelling in Second Life.
- Pervasiveness of Practice. Alluding to Jay Cross’ book, Dr. O’Driscoll paraphrases,“Avatars are free range learners and virtual social worlds are the learnscape in which they live.” The key to virtual environments is the pervasiveness of the phrase, “How do I . . .” In short, peer-to-peer learning is baked into the environment.
- Enrichment of Experience. Chris Davis’ Agora Ballroom demonstrates the enrichment of experience. Virtual worlds uniquely present the opportunity to augment or enrich real life experiences, and in some cases, to make experiences possible in the first place.

Dec 1st
I had the opportunity to watch a recorded archive of Dr. Lisa Dawley’s online presentation from Tuesday, November 27: Persistent Social Learning: An Emergent ID Model for Virtual World Design. Dr. Dawley (SL: Mali Young) is Chair & Associate Professor of the Department of Educational Technology at Boise State University and the designer of EDTECH Island in Second Life. The presentation focuses on what she believes is an emerging instructional design (ID) model for the development of virtual learning environments.
Initially, Dr. Dawley describes potential shortcomings of traditional ID models regarding the development of virtual learning environments and resources; specifically, the literature suggests the traditional models (e.g. Dick & Carey’s model and the more generic ADDIE model) are too process oriented, too static and too linear – leading to games or environments that don’t meet user expectations. I certainly understand the D&C model fitting into that category; I’ve always understood it to have more cognitivist, information processing philosophical underpinnings. The ADDIE model, as I understand it however, does not inherently have a cognitivist orientation; the instructional designer’s philosophy of teaching and learning influences specific strategies within the design phase, so the ADDIE model may be used to guide the development of more constructivist learning resources.
The challenge, according to Dr. Dawley, is to create a virtual environment that is engaging and draws learners in, and we can’t necessarily do that using traditional ID models. I agree entirely with that issue. I do believe there are two issues we, as an instructional design community, must address to meet that challenge. First, we must design and develop engaging virtual environments. Second, perhaps more importantly, we must design and develop engaging learning experiences within those virtual environments. I think the situation is somewhat analogous to an issue I’ve encountered recently regarding the use of iTunes: many colleges and universities are signing on with iTunes, but that’s only the delivery mechanism – the key to effective podcasting is the auditory content.
The presentation focuses on the first challenge: lessons learned while developing an effective and engaging virtual learning environment – specifically, Dawley’s work with EDTECH Island. For me, the first three phases of her research empirically corroborates the observational data published by Jennings & Collins (2007). For example, Jennings & Collins’ research compiled data regarding the educational institutions’ use of signage, pathways, maps and teleports on land parcels to facilitate visitor engagement and use of the space. Through the first phases of research, Dr. Dawley has collected empirical data validating the impact of those build design strategies; more importantly, her research also reveals the relative importance of building tutorials for learners, information sharing tools, meeting places, social/living areas, and group notices for increasing traffic and engaging visitors. As she summarizes, the evidence indicates navigational pathways and group notices have a definitive impact on engagement with social events and living spaces being less influential.
There were three other notable aspects of the presentation, in my opinion.
First, the data collection tools were new to me. I am familiar with visitor counters, but Maya Realities Second Life Traffic Analysis is quite impressive, to say the least. The metrics very easily evaluate the ROI of an institution’s SL space. I could try to explain it in detail, but it’s much easier to take a look at the presentation starting at the 25:30 mark (roughly halfway on the progress bar) and browse the Maya Realities website.
Second, one suggestion for increasing traffic to certain areas was to “put the milk in the back” – the grocery store notion of placing the highest volume product at the back of the store. That requires visitors to walk past everything else on the way to the high volume product. From a marketing perspective, that principle may work. From an instructional perspective, I believe it will be counterproductive. In any educational environment, we’re not trying to sell product; we’re trying to get learners to engage specific content in certain ways. Placing that content “behind” other interesting content which is ultimately a distractor is inconsistent with instructional and web design principles.
That leads to the third idea. An attendee suggested that we’re beginning to encounter and engage usability and design issues for virtual environments that are analogous to the earliest issues regarding the usability of web-based learning environments. Certainly, observing and participating in the convergence of architectural, game, instructional, and web design principles will influence the effectiveness of virtual learning environments.
