First, apologies, this post turned into a huge essay, but perhaps you'll find it interesting to see what happens in another school on a different continent!
A great many kids seem to lose interest in Art once they reach 5th or 6th grade… Middle School in the US. Part of this seems to be due to greater interests in sports and streaming games, videos, and music on their phones. Thinking back to my time as a students I’ll admit that the number of students who remained passionate about making art was limited. By Middle School most students develop a preference for a degree of “photographic” realism… and lose interest in making Art when they cannot achieve this.
Yes, this indeed seems common across cultures: by around age ten, kids suddenly want their drawings to "look right", and then give up in frustration when they cannot manage. I have seen this over and over: kids seemingly literally terrified to just make a mark on paper. It's partly an ego thing: they worry what their friends will think.
Seems there should be ways around it. In the days before cameras, pretty much all educated people learned to draw decently, because it was the only way to record things. One often sees this: you look at sketches drawn by non-artists, and think, jeez, the average Joe in 19th century England could draw better than many a professional, working artist today!
I don't know how 19th century drawing masters did it. Maybe they just beat the kids until they focused!
Teaching methods - and perhaps more importantly, goals - seem to have changed. I once saw a handwritten essay, written by Paul McCartney when he was ten. What struck me the most was how beautiful his handwriting was. Apparently, in his day, at least in British schools, there was nothing exceptional about it at all; that was the standard.
Nowadays, schools often seem not to care at all anymore what things look like: you see exercise books falling apart, no assignment has a date written at the top, headings not underlined, or roughly underlined without a ruler, completely illegible handwriting etc. I constantly see kids who do not know how to hold a pen when writing, and remember how, during my own early primary school days, teachers would patiently (and sometimes not so patiently) demonstrate it over and over, and correct kids that got it wrong.
Now I don't want to sound like your typical old geezer complaining how things were different in my days. But they really were different: aesthetics has left the building. Every year I run into kids in grade 4 and above, who quite literally cannot draw a straight line, or do simple measurements, with a ruler. But they all want to be mangaka.
You are right that many kids are hooked on anime… or cartoon imagery such as Sponge Bob. But then again… during my years in Middle School (or Junior High) and High School A lot of what I drew were images drawn from comic books.
How to engage the students? I have them do a lot of projects rooted in pop culture: emojis, Angry Birds, pop musicians, Disney & comic book characters (a lot of the kids wear clothes with Elsa (Frozen), Ariel (The Little Mermaid), and other Disney Princesses, Batman, the Joker, Spider-Man, and the Hulk. You can always build lessons around these images that explore concepts such as primary/secondary or warm/cool colors, movement, space (overlapping/cropping), texture, etc…
I have tried some of this, and indeed, also used their favorite anime characters. There's nothing wrong with anime as such; those artists are hugely skilled, and the art is often beautiful (with producers like Studio Ghibli, the art can in fact be quite breathtaking). But same problem as with anything else: the kids' ambitions hugely outpace their ability, and they end up disappointed, drawing after drawing. I don't know if this doesn't end up actually putting them off art rather than motivating them.
But more fundamental skills they do not want to learn, because that's for little children (you will never convince them of the sad truth, namely that little children produce far better art than they do!). Another problem is something you may have noticed: there is often a sharp difference between the sexes. Girls tend to be far more cooperative, and do not mind trying to do 'beautiful' art, whereas with boys at that age, as Betty Edwards noted, "taste reaches an all-time low." It can be difficult to reconcile the half of the class that enjoys drawing flowers and pretty ponies with the half that wants to show werewolves ripping victims to shreds or some such.
Background: some years ago I visited local schools to ask whether I could put up an ad for art lessons at their school. A Montessori School ended up offering to pay me to come in once a week to teach everyone from grade 4 to 7. The advantage is that they are fairly open about what and how to teach. But there are some unique challenges.
For one thing, all the kids from grade 5 to 7 are in a single class. Also, here in South Africa lots of kids are severely developmentally challenged, and private schools are often used by rich but clueless parents as a convenient place to dump them. The result is that I often have, in the same class, kids whose mental and fine motor abilities range from grade 1 to grade 7, and I am expected to teach them all the same thing. Inevitably the more developed ones get bored, or the less developed ones get frustrated.
Some years ago the classes were still quite small, and I could pay more attention individually; those kids rapidly progressed remarkably well, and I could teach all manner of fun things. I based many lessons on the book
You Can Draw in 30 Days, by Mark Kistler, in which he starts out with simple geometric forms and progresses from there to show how those can be used to construct all manner of things. The kids mostly loved it, because even a simple 3D cube that looks realistic was more than they could do at the time. So I had a few kids in class who had almost no talent or initial ability, but who became quite motivated and made good progress:
Since then the school has become more successful - but that also means larger classes with a broader range of ability (or, alas, inability), and more behavioral issues. Also, even in the few years since then, the worldwide disaster called social media has tightened its grip here as well. Maybe it's just my imagination, but in under a decade I seem to have noticed a marked decline in attention spans and willingness to do anything at all that isn't instantly entertaining.
I'm always in two minds as to whether I should indulge their pop culture tastes, or simply ram something more traditional down their throats. Anecdote: when I was their age, like most boys, I did not enjoy poetry lessons. But there was no way out: poetry was rammed down our throats. Little snippets of those poems still sit in my head, and I am grateful that they rammed them in there, because which kid would ever read poetry voluntarily, or develop even the most rudimentary appreciation of it without it being forced on them? (Admittedly, to this day I struggle to understand or appreciate poetry, but without those lessons, I would hardly have known that such an art form even existed).
Kids don't know what they want or what is in their own interest, so one needs to find some balance between forcing them to learn stuff, but also trying to make it at least somewhat enjoyable. Well, you would know how it is: the challenge can be both fun and very frustrating.
