| Abstract: | Recent research has to a limited extent explored the characteristics of students’ conceptual practices as sociocultural phenomena
in general and in science education in particular. I approach this issue by studying a group of students while solving a particular
scientific problem from A to Z, and as part of this analyse how different cultural means (the knowledge domain and the tools
in use) structure the students’ interactions and how their interpersonal relations change over this period of time. The aim
is to illustrate how these cultural means intersect in productive and less productive ways during the students’ conceptual
practices. The study has its point of departure in a design experiment where a group of four students, together with their
teacher, solve different problems related to the biological phenomenon of sequencing a DNA molecule (the insulin gene). Video-recordings
of the students’ interactions constitute the basis for this analysis. The cultural means strongly structure the students’
conceptual practices during their problem solving processes. Whereas the knowledge domain structured the whole process, the
significant roles of the website and the computer-based 3D model of the insulin gene were especially apparent during the second
part of the trajectory. The intersection of these cultural means appear productive in terms of disciplinary knowledge when
the students’ became aware of how to handle this relationship. The interpersonal relations between the students and their
teacher altered slightly in the beginning and became increasingly more fixed during the students’ progression. |
