Joint reasoning about gas solubility in water in modified versions of a virtual laboratory

Paper i proceeding, 2013

A virtual laboratory was designed to enable students to collaboratively discover the concept of gas solubility in water at different physiological conditions. The virtual laboratory was developed through a design experiment involving three successive versions with different guiding structures. Analysis of 13 dyads' reasoning about gas solubility in water revealed that the students' problem was to understand the concept of solubility of gases. It was also observed how the guiding structures within the three different versions influenced the students' reasoning about the concept.
