Ookie-dokie, I might be an old fart what is not in the know how kids this days study at школа (btw romanisation of this word is like 15 kinds of wrong on different levels, as this will sound weird af and not at all like russian sounds, but I digress). Long ago kids never ever do anything economy wise in elementary (grades 1 to 4, ages 7 to 10, after that is middle school grades 5 to 9, or up to 11 depending on what type of education student wants, also elementary school and middle school will usually be the same school facility), as it's a bit too heavy for kids of a young age, smthng like this usually was along the themes "where your parents work", and it was essentially the essay to teach the kids to write essays, as it is much easier to write about smthng the kid knows or won't be too awkward to ask. There is no group assignments in elementary at all, kids of young age are lil rascals and it's a recipe for disaster. Earliest group assignments became a thing is in grade 5 and it's less of a group activity and more of a we have a limited equipment for this physics or chemistry class, so kids go in groups of four. Also this assignments done in class.
Now what Alisa done in class was стенгазета (stengeta, literally "journal that goes on the wall") this was a thing in schools for grades 2 to 4, and it was usually a big class project on doing something big as a big collective. Usually on themes of nature, history or holidays, and in a playful way with a lot of drawings and some written text. This days (in 2000's and later when Alisa was a kid) that is a rarity as kids are all kinds of different today. But that was a common thing in soviet times and up till 90's.
Pretty much the only thing in this chapter done right is the looks of an inside of a school (but not architecture, it is clearly a bit more modern than at the proposed time Alisa was in a school and Vladivostok did not had it's revival yet), author got some nice refs.
edit: Oh, yeah, I forgot, anything Alisa wrote in her stengazeta is a lot weird, author clearly used a google translate. (and the theme as a whole is like 7 levels of weirdness)
