Expert/novice studies of conceptually rich problem solving have demonstrated a relationship between the correctness of a solution and the extent and organization of the solver's conceptual knowledge. This study examines meaningful problem solving and the relationship between the correctness of a solution and the extent of the solver's scientific…

Starting from a situated cognition perspective, this paper reports on the activity of 9th grade students who are interpreting the shape of a graph arising from the motion of a bouncing ball. In an unfamiliar context, informed by previous knowledge of similar experiments, the obstacle of understanding why the graph does not start from the origin is…

The interpretation of data and construction and interpretation of graphs are central practices in science which, according to recent reform documents, science and mathematics teachers are expected to foster in their classrooms. However, are (preservice) science teachers prepared to teach inquiry with the purpose of transforming and analyzing data,…
