This paper describes the following technological aspects of blended learning of mathematics: effective preparation of electronic teaching materials suited for different students' needs, videotaping of mathematics lectures, automated (self)testing of subjects taught using the computer algebra system Maple and preparation of interactive teaching materials with the MapleNet technology. Authors describe results achieved during preparation and implementation of these challenges in a Calculus course taught at the Faculty of Science, Masaryk University in Brno, in Autumn 2006.
