Revisiting Why Johnny Can't Code: Have We "Made the Print Too Small"?
theodp writes: In What is Computer Science?, the kickoff video for Facebook's new TechPrep diversity initiative, FB product manager Adriel Frederick explains how he was hooked-on-coding after seeing the magic of a BASIC PRINT statement. His simple BASIC example is a nice contrast to the more complicated JavaScript and Ruby examples that were chosen to illustrate Mark Zuckerberg's what-is-coding video for schoolkids. In How to Teach Your Baby to Read, the authors explain, "It is safe to say that in particular very young children can read, provided that, in the beginning, you make the print very big." So, is introducing coding to schoolkids with modern programming languages instead of something like BASIC (2006) or even (gasp!) spreadsheets (2002) the coding equivalent of "making the print too small" for a child to see and understand?
Please stop shilling for Facebook. You do it endlessly. No one likes Facebook or its douchebag in chief.
The statements are too long.
Writing a working program should be as easy as:
LOL
LMFAO
ROFL
Therefore I suggest we teach beginners assembly language and exchange the mnemonics for common texting short forms.
"It is practically impossible to teach good programming to students that have had a prior exposure to BASIC: as potential programmers they are mentally mutilated beyond hope of regeneration."
-- Edsger W. Dijkstra
Kids should be introduced to programming using marble runs and physical switches or conditionals. Get them interested in the toy aspect, introduce rewards for working out how to achieve goals, and gradually introduce virtual modelling of the physical layout as complexity increases - they will gradually move completely to the virtual model, and then you can introduce the next stage of exposing the code when managing click and drag objects becomes a hassle.
Baby steps. Literally.
Maybe Johnny wants to choose his own fucking interests, instead of having them imposed by a corporate oligarchy only interested in cheap labor.
SJW's don't eliminate discrimination. They just expropriate it for themselves.
I have seen a lot of programmers who are totally dependent on the IDE to develop the code. They have no idea how it works or where it runs from once it deploys.
The need to solve a problem, being presented with a tool simple enough to understand and some help to get started seems to me to be the true trigger that can start someone off down the programming track.
Of course we have made the print too small. I recall attempting to 'grok' Fortran and Algol as a teenager and having difficulty understanding the difference between reserved words and variables and so forth.
BASIC is a brilliantly-designed language for the beginner because the concepts you need to understand are so simple. Even the much-maligned line numbers are important in the learning curve. When you start, a variable, a reserved word and a label are all concepts you have real difficulty separating. BASIC line numbers, though, you can immediately map to the idea of a sequence of control. Once you have mastered this you can then absorb the more advanced concepts gradually.
For those who take a snobbish attitude to BASIC I still feel that Kemeny and Kurtz understood absolutely how to create a language that simplified programming to its essence. As such, it really should be the starting point - it's easy to teach students better techniques once they have written some simple BASIC programs and hit issues like running out of places to insert a line, etc, because they can SEE why better techniques make their lives easier.
I think there's something to be said for learning programming on a very simple machine.
First, you need to keep in mind that kids have absolutely no idea how a computer works, at even the most basic of levels. It's a box with a keyboard and stuff happens on the screen. You need to cement the idea that you have to tell the computer to do stuff, and link the idea of coding to that stuff.
This is much easier to do when you have a computer that does pretty much nothing when you turn it on. A flashing cursor comes up and it's waiting for you to tell it what to do. 10 PRINT "HELLO" RUN and it does something. 20 GOTO 10 RUN and it does something else. You get the link between what you're telling the computer to do and what the computer is actually doing pretty quickly.
Compare that with booting up Windows/MacOSX/Linux, getting into your desktop environment, loading up a browser or IDE, creating a new project, explaining the UI of the IDE, making sure you have the right includes to do IO, directing your output to console or a UI object, etc...

When I was a kid getting into programming, I constantly ran into a wall. The basics, like hello world, and command line input->output programs that can do an enormous variety of calculations, background work, execute even big and fun commands were always easy, instructions prevalent, how to's everywhere and easy to understand.
Then you want to actually move from moderately complicated programs that are useless to real ones that do something, and I hit a wall. How to make a GUI work, how to make graphics appear, how to do anything useful at all in any kind of app, desktop program, etc, and the tutorials jumped from 5 easy to understand lines to 50 page books on how to get a single line to appear, much less do anything else.
Excessively complicated syntax, and extremely difficult, complicated programming required for even simple programs in a useable context make it opaque, that is the small print. The resources are plentiful for the most basic coding, plentiful on algorithms and how they work, but the second you get to a moderately complex topic of actually making applications you can double click and use, I might as well be trying to learn how to do complex multivariable calculus in a non-euclidean geometry based on a few comments on a thread on a help page that was posted and died 8 years ago.
I never hear of it. What's it? I even try go there today, but website is down. Maybe I tomorrow try again if it is good site.

Here in Australia, a TV show called "Good Game SP" (which does gaming news, game reviews and other gaming related stuff aimed at kids) did a series of segments using the Scratch environment to build a game. I thought it was a great way to introduce kids to programming in a simple way (with things like if statements, loops etc) but without (as far as I can tell) teaching any of the bad habits you might get from something like BASIC.
The LEGO Mindstorms robotics kit also seems like a great way to teach the simpler programming concepts without teaching bad habits (coincidentally both LEGO Mindstorms and Scratch came out of the MIT Media Lab)
for decades. I learned it when I was 7, learned basic when I was 9 and was using proper programming languages within 2 years of that.
Give them LOGO and turtle graphics.
It was the best tool for the job in 1967. It's still the best tool for the job today.
The reason is because nobody has tried to build a better one. You don't teach 7 year olds ruby or javascript or python but FFS you don't teach them BASIC either - give them LOGO, and when they mastered that, they will be able to grasp any modern language you throw at them.
And if you want something new and shiny, then design that something FOR CHILDREN. That's why LOGO remains the best for the job - because it was designed specifically for children by a team that included a behavioral child psychologist.

Johnny can't cook a souffle, Johnny can't make a dove joint, Johnny, can't fix a car, Johnny can't set a broken arm, Johnny can't balance and income statement, etc.
But there is at least SOME people that can do it. These are all disciplines/careers that people elect to pursue. Not everyone needs to know how to code. That's stupid. Does everyone need to know how to design, cut, and sew together a pair of pants?
Does knowing how to code make it any better when Windows or Windows apps go toe up? Really? Are you going to debug Windows or Mathematica because you took a coding class?

As the parent of a 12 year old girl, I can assure you all, kids today are not having trouble learning to code. They have resources today that I couldn't have dreamed of when I was their age, and they are using them. There are two major problems that I see happening: there are too many languages out there and no one works in text/console mode anymore.
Computers were text based when I was learning basic 3 decades ago. As such, BASIC made a perfectly sensible starting point. Instead, today, a web or mobile app requires knowledge of HTML, JavaScript, CSS, some backend language such as C# or Java, SQL, and probably some other things AI haven't thought of.
Really, if you want to bring back a version of BASIC that was reasonably accessible but could still write something resembling a modern app, bring back Visual BASIC 6.
But like I said, kids today aren't really having much of a problem. My kid and her friends are learning JavaScript and C# and C++ and I have no idea what else. There are lots of resources out there and kids are taking advantage of them.
Johnny (and Jane) can code. They just don't want to. Back in the 80s and 90s, computers were new and cool and if you could code, you could even make the computer do what you wanted it to do. Back then coding was freedom. It's like hot rods in the 50s. If you could soup up a car and make it run fast, others looked up to you. Now, fast cars, like computers, are common place and the "skill" isn't needed or valued like it was.
In the future, today's hot fields will be asking the same question. Once the newness and prestige wear off, the Johnny's and Jane's of the world move on to something else.
The reason Johnny (and Jenny) can't code is simple: coding is not easy. Most kids hate math word problems. Yet, that's what coding is. You're given a math word problem with all these variables and facts and rules, and you have to come up with a solution, that is translated into a foreign language of simple instructions for a very dumb machine that is fussy about how you talk to it. If you can't stand problems that start out, "A train leaves Chicago traveling 42 miles per hour...", then you are not ever going to like coding, and you most likely will never be very good at it.
