Streaming, bandwidth and the "YouTube effect"

This will not be a well thought-out post... more likely the general ramblings that were the basis of blogs, so let's dive in!

In K-12 technology, there's an ongoing and growing dichotomy (or it seems so) between those who want to be more open about Internet access and those who want to (choose your phrase) block, filter, lock it down, control, police access to the web. Both sides have valid points and I'll try to touch on them briefly:

Open it up, we filter too much as it is - Who are you, technician and non-educator, to say what is or is not relevant to my students' instruction? Do you not trust the teachers, degreed professionals, to properly manage their classrooms and the students' Internet browsing habits? Filters are notorious for blocking legitimate web content along with "bad sites". YouTube has tons of educational videos! I can use Pandora to teach about various cultures and their musical backgrounds! If the kids are spending their time on Facebook, why can't they use that environment in school? We can't ask them to unplug or turn off when they enter the school and expect to hold their interest! HELP!!!

Block those sites - I have a responsibility to manage the environment for everyone. Bandwidth is not unlimited. Do you know what happens when hundreds (or thousands) of simultaneous connections are made to streaming media sites? You're the ones complaining about slow Internet access and I'm trying to help. Have you seen your Internet logs? If I open up YouTube for students, bandwidth use will skyrocket and it will all be a bunch of YouTube usage! We have teachers that are not on task and that are allowing kids to play poker. Music? Let kids use their iPod because I can't have everyone streaming audio. HELP!!!

What we're talking about here are resources, utilities... and opportunities! As tech leaders, we need to run with the utility analogy and help educate our educators. As tech leaders, we need to wake up to the fact that there are TONS of educational resources on a site like YouTube. What is a flipped classroom? How do I tie a Windsor knot? How do I sharpen a lawn mower blade? Can the Oak Ridge Boys sing 'Seven Nation Army'? So, yeah... you can find pretty much anything on YouTube. It is a library. We don't keep our kids out of the library! Sure, not every book in the world in in our library and there's a time to be reading Shakespeare and a time to be reading Sports Illustrated.

As with any utility, though, there is a responsibility to promote proper use and there's a need to realize that the resource is limited. My good friend Marty has convinced me that kids can often focus better on tests with instrumental music playing. We might argue over whether hundreds of concurrent music streams or iPods are the better solution, and proper resource management is a factor. Hopefully, though, we can get past the fact that all [insert here: streaming media, social networking, etc] sites are bad. True, we have to manage utilities and everyone can't flush their toilet at the same time. Cutting peak demand can sometimes lower your electric bill.

Like your utility provider, IT staff DOES have a responsibility to help educate others and, yes, potentially help manage bandwidth as a resource. However, the school district or company as a whole needs to be involved in the conversation about the solution. The solution may be to restrict high-bandwidth content at times, and the solution may simply be to find more bandwidth for the benefit of your users. Educate and inform, but don't make that decision in a vacuum on behalf of your users.

Thoughts on TMG and Internet filtering in general

As many of our school districts are looking at implementing Microsoft's Threat Management Gateway, now is as good a time as any to put a few thoughts together:

With the penetration of 3G handheld devices in hands of many high school students and staff, some districts are rightly questioning the effectiveness of ANY content management solution in an environment where a personal device cannot be monitored. That said, school districts are obligated by CIPA and (in our case) state law to do something in an effort to prevent access to inappropriate material.

At this point, it gets difficult for many districts. Depending on the expectations that have been set over years of content filtering and management, classroom teachers and administrators often expect the technology department to stop any inappropriate access from occurring. Technology leaders know that this is not possible. With time, opportunity and motivation, virtually any filtering solution can be defeated or bypassed. If the expectation has been set from the beginning that these matters are handled in the classroom, then the changing landscape of devices and methods of access may not have a huge impact on the prevention of inappropriate access since it would still be attempted and dealt with at the classroom level.

As our districts are considering Threat Management Gateway, I've noticed a few things that are worthy of note. First, the URL filtering is a subscription-based add-on that is referred to as the "Web Protection Service." This service provides subscriptions not only to URL-based categories but also to malware filtering. Issues with malware have become very important to our technical staff due to time spent cleaning up infected devices.

Note also that SP1 enabled certain features such as URL override and reporting enhancements, including a detailed "user activity report." My first reaction is that these enhancements should have been in the native product rather than a Service Pack, but the fact remains that they are now included and that's a positive development.

In fact, I think that generally sums up my initial thoughts about TMG. If a school district is simply trying to meet the letter of the law and wants a solution that can filter URLs based on categories and can potentially help with malware, TMG might be a fine solution. Some districts have paid for much more expensive and elaborate solutions that allow for robust reporting and real-time monitoring of particular users. I'm not trying to slander the TMG product and imply that it cannot do these things, but there's a reason that these other companies charge a premium and I can only assume that it's due to some advanced features, perhaps ease of use, etc. If you desire some of these advanced features, other products may fit your specific needs.

I'm inclined to compare this market to the old debate of VMWare and Hyper-V in the virtualization market. VMWare was earlier to market and has a strong reputation in this market. Microsoft's Hyper-V offering was later to market and, at least initially, might not have had all of the features that the VMWare suite had. At the time, one could market higher cost for higher quality while the other marketed a lower-cost product that provided all of the features that many customers might want. I think this is how I would currently categorize TMG. It provides many of the features (if not all) that many customers in this market desire.

At any rate, all of this is subject to change but it's what was on my mind at the moment. This and 50 cents would have bought you a soft drink several years ago. :)

Latest on the "internet filtering" conversation

I probably write about this too much. I hear from multiple school districts about issues they're dealing with. Some district leaders are trying hard to filter as little as possible, believing that most of the underlying access issues are not related to technology. Other districts have been the victim of an unfortunate event that brings this topic to the forefront and inevitably leads to more focused filtering.

This is just a quick entry to "take the temperature" of what's out there. To get this information, I simply entered a very general phrase regarding internet filtering into a search engine and reviewed a few of the top results:

* Good blog entry by Wesley Fryer, who helps organize a free K-12 online conference. Lots of good comments and links in this blog entry. As he puts it, "...it's hard to learn to swim without getting wet." I got caught up in looking at links within links and ran across a reference to "The Death of Common Sense", which is a good book that looks at some examples of how the fear of litigation has altered our behavior.

* An EdWeek blog entry that mentions a North Dakota example where educators are pushing for less-restrictive filtering policies.

* A very telling quote/blog entry featured on Scott McLeod's "Dangerously Irrelevant" blog.

* A brief question (and lots of good discussion) on the Classroom 2.0 forum.

These were on the first page of my search. I feel like that many of my districts have learned that "the more you block, the more you will be asked to block." Some users have been conditioned to assume that the tech department is (or should be) the "Internet police." Lately, I've heard from a few who lament the number of sites they're asked to unblock.

It's interesting to see how this evolves, especially in a society where the pace of technological enhancements far exceeds that of internet filters, knowledge of users and educational policies in general.
