TL; DR - filmerna är otroligt opålitliga.
Processen att lära stava är mycket mer utdragen och svår än filmerna indikerar. Eftersom böckerna mer eller mindre svarar på denna fråga kommer jag inte göra mycket men ge offerter. Här är några från de första veckorna som Harry är på Hogwarts.
And then, once you had managed to find them, there were the classes themselves. There was a lot more to magic, as Harry quickly found out, than waving your wand and saying a few funny words.
They had to study the night skies through their telescopes every Wednesday at midnight and learn the names of different stars and the movements of the planets. Three times a week they went out to the greenhouses behind the castle to study Herbology, with a dumpy little witch called Professor Sprout, where they learned how to take care of all the strange plants and fungi, and found out what they were used for.
I McGonagalls klass ...
Then she changed her desk into a pig and back again. They were all very impressed and couldn't wait to get started, but soon realized they weren't going to be changing the furniture into animals for a long time. After taking a lot of complicated notes, they were each given a match and started trying to turn it into a needle. By the end of the lesson, only Hermione Granger had made any difference to her match; Professor McGonagall showed the class how it had gone all silver and pointy and gave Hermione a rare smile.
Flitwick och Wingardium Leviosa ...
"Now, don't forget that nice wrist movement we've been practicing!" squeaked Professor Flitwick, perched on top of his pile of books as usual. "Swish and flick, remember, swish and flick. And saying the magic words properly is very important, too -- never forget Wizard Baruffio, who said 's' instead of 'f' and found himself on the floor with a buffalo on his chest."
It was very difficult. Harry and Seamus swished and flicked, but the feather they were supposed to be sending skyward just lay on the desktop. Seamus got so impatient that he prodded it with his wand and set fire to it -- Harry had to put it out with his hat.

"You're saying it wrong," Harry heard Hermione snap. "It's Wing-gar-dium Levi-o-sa, make the 'gar' nice and long."
I duellerklubben i Secret Secrets, Lockhart (försök) för att ange hur man blockerar / pariserar (intressant ser vi aldrig hur detta verkligen görs, även om några av de vuxna gör det ibland).
He raised his own wand, attempted a complicated sort of wiggling action, and dropped it. Snape smirked as Lockhart quickly picked it up, saying, "Whoops -my wand is a little overexcited -"
Halvblodsprinsen tar oss genom att lära sig Apparate, vilket är ganska nära att lära sig att köra. Det tar minst flera veckor av lektioner, och du måste klara ett test eftersom det är extremt farligt. Harrys första försök ...
Harry spun on the spot, lost balance, and nearly fell over. He was not the only one. The whole Hall was suddenly full of staggering people; Neville was flat on his back; Ernie Macmillan, on the other hand, had done a kind of pirouetting leap into his hoop and looked momentarily thrilled, until he caught sight of Dean Thomas roaring with laughter at him.

The second attempt was no better than the first. The third was just as bad. Not until the fourth did anything exciting happen. There was a horrible screech of pain and everybody looked around, terrified, to see Susan Bones of Hufflepuff wobbling in her hoop with her left leg still standing five feet away where she had started.
Slutligen notera att det bara är en framgång att bara stava på jobbet - du måste behärska den. Här är en kommentar om den första års omvandlingsexamen -
Professor McGonagall watched them turn a mouse into a snuffbox - points were given for how pretty the snuffbox was, but taken away if it had whiskers.
Det här är ett kontinuerligt tema - karaktärer som spelar stavar att bara hälften arbetar, eller 80% arbetar, och en inriktning i undervisningen verkar vara att få detta upp till 100% -markeringen. Med andra ord handlar det inte bara om att få en stavning att fungera, det är att få det till jobbet rätt , på ett konsekvent sätt.
Jag kommer inte att inkludera några mer citat, eftersom det är mer om att stapla små saker än några stora förklaringar (måste behålla den magiska vaga).
