Abstract: 

We present an instructional sequence on analyzing one- and two-dimensional data sets. This instructional sequence is based on teaching experiments in a 7th-, and 8th-grade classroom in Nashville, TN. The sequence we present here, however is not just a smooth version of the sequence that we have tried out. What we learned during these teaching experiments made us reconsider a lot of the original instructional activities. The aim of this paper is not to present the result of these considerations as a ready-made instructional sequence. Instread, out min objective is to offer a rationale for a revised instructional sequence. This rationale is construed from the following ingredients: original considerations that formed the point of departure for our teaching experiment, experiences in the classroom, re-considerations, and new insights.
