Blacklist vs. “Walled Garden”
Schools have different ways to give kids access to information.
They can use books, curated digital tools, or more open internet environments managed with filters and blacklists. It is their choice, but regardless of what they choose, schools have a duty of care to our children.
Each choice above has a different set of benefits, costs, and challenges. They are not the same.
Blacklists are most popular, and it basically means the school issued device starts off with full internet access, and the school or their IT or district “block” places that are not appropriate for kids. This is the system that likely has the “most” amount of information available to a student.
Whitelists (Walled-Gardens) on the other hand, start off with everything blocked, and the school or IT person “adds in” what is safe and allowed. The amount of information here is typically less than in a blacklisted environment, but more than a “school book” environment. Many sites a school may want are built off an open internet model and certain functions may not work or work well.
Books - well, they are books. They can be previewed in advance, the material doesn’t change outside of the school’s control at any given time, they don’t generate new ideas spontaneously, but they are limited in the amount of information available. An example of why books may be a very complete way to educate kids are 1.) no one ever complained that a school library didn’t contain “all the information in the world”, or that children were limited academically because their school library was too limited. And never forget, parents always had the opportunity to expand information for their child by taking the to a town or county library, or buying them more books. That being said, it would be easy to show any one website and claim it’s value to kids to have access to.
The issue schools need to manage are:
Who controls the information that kids can access through school? (The school, or people outside of the school).
Who is liable for what kids can access?
Many parents do not allow their children access to the open internet, they have no access or basically a whitelist environment and are against schools allowing access to information that is not directly tied to their school work.
Schools have invested a lot of time and money into devices and switching to things like Google classrooms.
Blacklists were built on one basic assumption: that risk lives at specific websites or apps you can block. Even though that was hard to keep up with, it was still bounded.
But generative AI changes that.
Now, the risk isn’t just where a child goes, it’s in what the system generates in real time, inside the interaction itself.
That means you can’t pre-review it, and you can’t fully control it with a blacklist.
So when schools say they’re “managing access,” that no longer answers the real question:
Who is responsible for what the system is saying to a child?
Because when risk moves inside the interaction, filtering alone isn’t governance anymore.
And with kids, we don’t rely on partial control — we rely on accountable adults managing the environment.
Start with: “All information in the world”
Before the internet & 1:1 devices for kids: We had libraries in schools. They were curated, they were limited in scope. No one complained “this library doesn’t contain all the information in the world”. Teachers, students, families accepted that even if it wasn’t perfect, even if something may have been missing, it contained alot of useful information for students. There were heated debates over “book bans” - should a specific book be included and made available to a student or not. But regardless of what the school decided, parents ultimately had final authority. Parents could give additional access to their children by taking them to the town or county library or buying books for them. School gave limited, approved information. Parents could give more.
When the internet and 1:1 devices came into schools, parents were told “technology is the future” and “your child has access to the information of the world”. The assumption = more information is beneficial to children. (And you can argue any single case to prove this is true (child “A” was positively affected from getting access to information “Y”, but it became harder to track or measure if child “B” was negatively affected by having access to information “Z”). Regardless of what is true, we didn’t have the governance to properly measure this. It’s easy to tell a story about Child A, it’s hard to get the data to tell an accurate story about Child B. So it’s easier to speak about the benefits, but much harder to articulate or show data to discuss Child B.
Governance Issues:
As Kids were given full access, and as Schools are not Tech Professionals, they took on the job of trying to “reduce” the open internet into something reasonable for kids to interact in. If you have ever tried to do this yourself for your children, especially as they get older, you will see how impossible it gets. Parents often give up, or just keep it away as long as possible, but it’s not reasonably managable, in part because everything digitally is constantly changing with no change control abilities for schools or parents. So it’s a never ending job where you are always on the defense.
Can a responsible adult or institution define, verify, and enforce the boundary of a child’s digital environment?
There was a time they likely could do this in a reasonable way. It is now out of control and nearly impossible to manage.
Blacklist
“Block what you don’t want”
Boundary = undefined
Control = reactive
Verification = not possible in advance
Default state = accessible unless blocked
Typical School Library “Limited information, curated for children”
Whitelist
“Add what you want”
Boundary = explicitly defined
Control = proactive
Verification = possible before exposure
Default state = blocked unless approved
Observability: You can enumerate all allowed environments
Responsible Party Defines
