The present paper describes an attempt to alleviate some of the difficulties and misconceptions about the concept of function, by integrating a computer implemented learning environment with specifically designed activities in a curriculum covering functions. This curriculum-the TRM curriculum integrates open-ended activities with a "conventional" approach to the concept of function, and "computer" sessions with normal classroom activities. Typical problems and comments on student activities are given. Comparative investigations led to a cognitive classification of functional reasoning. Some practical issues arising from teaching about functions and pedagogical engineering are described at the end of the paper.
