How Do You Teach Everything in IT?

At the lowest levels things are relatively unchanged. We are still using binary for computation. Most of the physical systems are, in essence, comparable to what was used 10, 20 years ago. But if you compare it to medicine for example the complexities seem larger in comparison. In medicine you constantly have to learn new drugs and techniques, but the thing you're working on remains unchanged. In addition, your day-to-day, entry level tools remain the same. In IT, aside from the most basic of diagnosis (ping, traceroute, nslookup, etc.) the tools change rapidly.
I'm not saying this isn't a worthy goal, and should not be attempted, just that it is daunting to contemplate.
But initially, what I would want to teach would be the theorisms behind the various IT disciplines -- the generalist level stuff. That really doesn't change at such a fast pace. Things like Binary, as you mentioned, or subnetting (even in IPv6, the math behind it doesn't change... there's just more digits, lol).
Even programming hasn't changed much. Sure, there's new languages, and the semantics are highly different between them, but the core of the code almost always looks similar in a lot of ways (at least to me). But the programming languages change relatively rapidly when compared with something like RAID, or the OSI model.

This is interesting as I've been wondering about this sort of thing.
Example, Scott has been discussing with me in another thread about thinking about a LANless setup. Question is how and where do I learn this sort of thinking from. I'm self taught in all areas of IT so I still think in terms of LAN/WAN as that's what I've been doing for 14+ years, but where do you get the ideas and guidance on new ways of thinking? Is it from attending things like Spiceworld or other conferences? Or are there good online resources to see what people are doing and how?

As iron sharpens iron, so does one person sharpen another.
I've learned more from folks like @scottalanmiller in the short time I have interacted with him on here and in Spiceworks than I have the last 10 years I've spent in IT.

I agree. I've learnt so much more in the last 2-3 years from just being on SW and here it's amazing.

The biggest issue with these communities is becoming a monoculture. If any one person or group of people dominates the discussion without room for new ideas and approaches a community becomes part of the problem. This is not a passive aggressive way for me to call someone out, just something for everyone here to be careful of.

That's what ML is!

This is definitely true. That is one of the reasons I have stuck with IT so long. It's that with every job or project that puts me in contact with other folks allows me to make room for new ideas or new ways of thinking.

This is a huge problem and one that sadly plagues both SW and ML, heavily because of me. In both cases I was foundational in the starting community conversations. So the people who got involved were often either there "because they agreed and wanted support in that direction" or "they disagreed and wanted to argue the other side." What grows up rather naturally is a culture not of a single opinion, but of two opinions that are both rather myopic. One is "I think SAM would say this, therefore I'll do that" and the other is "SAM is an idiot, so I'll avoid the solution I think he promotes."
What makes it harder is that as a community grows that skews away in odd ways. So many people who think that they are repeating me are actually saying something I would never say and have never said, but have become famous for even though it wasn't me. And so you get two groups often trying to follow advice or ideas that were never given or not in the way that it is assumed.

The monoculture or duoculture problem arises around all kinds of things from interest areas, to solution sets, to vendors and product choices. You see it in vendors who get lots and lots of attention in certain communities just because it is a vendor that is heavily used by one or two prominent people. Not that that is all bad, the IT world is chock full of pointless vendors with products that have no value or place in the market. Eliminating them from conversation is generally good. But this produces false positives with other vendors that no one knows or has experience with getting ignored unjustly.

This is why I think it is important to express personal opinions and state them as such. it doesn't matter if I think @scottalanmiller and @Kelly would hate it. I would say my piece and then tag you both on it.
The biggest problem that I see is that most folks once they have reached the @scottalanmiller would say... or @Kelly would say... stage is that they have given up thinking for themselves, in a lot of ways.

@dafyre and @scottalanmiller I agree with your statements regarding the fundamentals. The number of IT pros that I have encountered who do not understand subnetting is disappointing. That being said, I think that the problems start when you leave the basics. Using your example in the OP @scottalanmiller, you had never heard of a given tool that a customer considered normative. I'm running in to this on a nearly daily basis as I transition from Windows Admin to Linux Admin. I have no idea what is normative (other than what is mentioned here and elsewhere), and that is a moving target at best.

To give a concrete example.... I've done a lot of talking about RAID, mostly not here. What I think people miss is that the ideas I espouse are mostly just repeating really good information from Microsoft, Oracle and ZDNet (Robin Harris) who have done a lot of research in this area. I just talk about how their information applies to the modern landscape. I've done a lot of research on my own, of course, but nothing I have said ever disagrees with those three or, really, any RAID research I have ever seen.
But things that I say, like that RAID 5's place on Winchester drives is long gone given the factors affecting modern Winchester drives is often distilled to something quite different like RAID 10 is the only viable RAID level. That's very different. It's also often assumed that somehow that means that RAID 5 never made sense, which of course is nonsense. That would be like saying that gasoline was a dumb idea now that electric cars are available - how silly we were to buy gas cars all these years (but ignoring the fact that electric cars didn't exist yet.)
So there has become two cultures that I see - one that thinks I'm promoting RAID 10 as the one and only answer and repeats that rather strongly (I agree it is the most common answer, but just barely) and another that wants to spite me and basically says that all attempts to research RAID or business factors is dumb and you should always run RAID 5 and not consider cost or risk or performance just because "screw SAM" for caring.

That will always be a moving target, I think -- especially as new tools come and go, and you get experience with different OSes (Windows vs various Linux Distros / *BSD, etc). Customer A might use Robocopy... Customer B might use Free File Sync, and Customer C might use some variation of rsync on Windows. All 3 can accomplish the same task... but various customer mentalities will almost always challenge the perception of "normal".

I'll agree with that as a problem. I'm less concerned with figuring out how to teach what is normative in a specific area of specialization, however, as in doing so for the generalist as a base of shared knowledge. Specializations are much more of a moving target and once to that level, people have more responsibility to be more critical in their assessments of things, I think.
If you are a well educated, properly thinking generalist with a broad set of knowledge I think that your ability to avoid bad trends in specialist areas is much easier.
Sure you might miss big things and always use RPM manually and not realize that everyone uses YUM to make things easy, but that is easy to correct later on.
I had a long history of UNIX administration before I was introduced to automounting. Doesn't mean I was a crazy UNIX person before that, it was just one more skill I had to add on later on.

This is sadly super true. Although I think that it highlights an importance to producing a base for specializations as well... the ability to show potential employers more or less definitively that what they expect an outsider to be familiar with is common or niche.
Most of us have probably had interviews for a position that we felt that we were far too senior for and yet they felt we were unqualified idiots because their view of that job was totally different from ours. Sometimes with things that are completely unrelated. Like randomly assuming that all Windows Admins know Exchange. I was an MCSE+I, had used Windows in the enterprise for years and often was not even in an environment that used Exchange let alone was the admin for it. Only a small subset of Windows Admins will ever see Exchange, yet some shops just assume that they are one and the same.
And then people might randomly assume that you manage everything through VBScript, but you only know PowerShell or JScript. Randomly people might assume you can program or that you will never, ever use a command line.
I actually find the Red Hat certs hard because they assume lots of skills only entry level desktop admins would ever use or see and anyone at even an entry level server level would be unlikely to even know exists (GUIs for printers, for example.)

If someone could give me pointers to reinforce critical thinking skills with green IT Staff, I would be eternally grateful. Experience plays a large part in knowing which questions to ask during that process, but other parts are just "common sense" to some people while completely foreign to others. From reading error messages to services breaking, IT people need to dig deep sometimes to resolve an issue. When training staff, I usually ask them the same questions that I ask myself internally. Ex - "What is related to this process that could affect this failure" (Scope & Environment), "What does that error message mean? Break it apart and take it one part at a time"
I have a saying/theory/whatever: There is always a point where you look at technology and consider it a "magic black box". This is where your understanding ends and it "just works". IT people need to be many, many layers deeper than the average user.
The concern is how to prep IT People to push deeper when they hit the "magic black box" so that A ) They dont stop or get frustrated before they fix the problem & B ) Their understanding and knowledge improve which helps reduce the "magic black box" issues
Also I always stress consistent testing environments for new staff. Your hour of testing means little if important factors are not tracked that could influence this issue.
Feel free to improve my saying (or completely refute it if you disagree). Im always open to improving my management and training skills.

You've nicely summarized why I'm taking an old MacBookPro home tonight as well as fighting with linux to make it do my bidding in any of several flavors. My days of being a windoze only admin are drawing to a close.
Tangentially related: I need a better paying job really badly. I'm open to offers / ideas, please msg me or whatever.

That's a great perspective, I like that. At some level, everything because a magic black box to everyone; it's just different levels.
