ATTENDANCE OF SEMINARS IN TRADITIONAL AND BLENDED FORMS OF EDUCATION by I. V. Kharlamenko

“…The author gained the data on attendance of seminars by the 4th-year students in the biological department ofMSU and applied mathematical methods to process the data. The attendance of seminars by students has been analyzed in two educational forms: traditional learning (face-to-face classroom seminars were accompanied by autonomous paper work) and blended learning (face-to-face classroom seminars were accompanied by autonomous work on a specially created educational wiki website). …”
