Analysis of questionnaires showed that the teachers were satisfied with the work with SSI. They found the
introductions and the contents interesting, and experienced that the students were engaged. The teachers found
the learning goals were appropriate in relation to the syllabus, but not as much to the students’ prior knowledge.
In general, they used between five and ten hours for each case. Forty percent of the teachers taught part of the
topic before introducing the case, and 60% of them introduced the learning goals early. The teachers used a
variety of work forms, and group work was frequently used. Only a few included lab work. The most common
resource was Internet. The teachers indicated that the students had learnt as much as they usually do in science.
The students learned critical thinking, to search information, apply scientific knowledge, scientific facts and
understand scientific facts and argumentation. The seven interviewed teachers appreciated getting a material
with new ideas and they saw benefits beyond the actual work, e.g., involvement from parents and a lasting
interest in the contents among the students. They gave several examples of how ideas emerged about the
development of science teaching in general.
