This paper deals with possibilities of usage of language corpus SCHOLA 2010 for research of school communication. Language corpus SCHOLA 2010 is introduced and some possible ways of its usage are demonstrated on instances of research of utterances with expressive communicative function (expressive illocutionary force).
Author concludes that this corpus is useful for research communicative functions indicated in direct way, but users should be careful when they want to use it for researching indirect ways of accomplishing to communicative functions and author means that another instruments (on basis of linear text - for example rewriting of audio or video records of communiation in school classes) may be more suitable for these goals.
