Your question is a little unclear. What does "what happens with an education system" mean?

I've genuinely never seen this happen, maybe you should ask the people that you've seen doing this. But here's my best guesses:

1. In English, you capitalize letters of "words that carry meaning" (I don't know the correct term, but I mean nouns, verbs, adjectives and such, but not prepositions and such) in a title. For example you would write "The Lord of the Rings". The first "the" is capitalized, because it's the first word of the sentence, and "lord" and "ring" are capitalized because they are nouns.

2. In german, all nouns are capitalized, not just the first word in a sentence, so if you saw germans do it, it might be a that.
