In the paper we describe the part of the history of Olympiads in informatics in the Tatarstan Republic, Russia which connected with the Kazan Federal University. It began in the 80s of XX century and now there are several centres of Olympiads in informatics in Tatarstan and one of them is the Kazan Federal University. In the second part of the paper we describe the current approach to organize the lessons on informatics. The main idea is a seamless transition from "lessons 1.0"(teacher prepares all materials for students) to "lessons 2.0"(students prepare all materials for students), like the transition from Web 1.0 to Web 2.0.
