Abstract

Stochastic prognoses are assumed to be a key concept for elementary school stochastics. They may be characterized by the following structural components: focus, evaluation and justification. A qualitative research project with third graders (age 8-9) was conducted in the frame of epistemological interaction research (Steinbring, 2009). The aim of the study was to learn about elementary school students understanding of stochastic prognoses. The study encompassed pre- interviews, a series of lessons and post- interviews. The contribution aims at analyzing and comparing one student’s understanding in the pre- and post-interview. The data used for analysis are transcribed episodes from the pre- and post-interview. The analysis and comparison gives insights in the students developing understanding of stochastic prognoses.
