The design of a Mathematica-based learning environment for ordinary differential equations (ODE) is discussed. The ODE package consists of hypermedia-based
information about differential equations and a collection of different kinds of exercises. The purpose is also to collect
data about the student's work and behavior during the computer sessions using a recording system created as a part of the
package. The data is used to analyze the learning process. The final goal is to get more knowledge about appropriate ways
to use computer algebra systems like Mathematica in mathematics studies.
