56. Question 1 demonstrates how the 2015 framework largely maps onto the same categories as
the 2006 framework, using the same competency and context categorisations. The 2006
framework included two categorisations of scientific knowledge; knowledge
of
science (referring to
knowledge of the natural world across the major fields of science) and knowledge
about
science
(referring to the means and goals of science). The 2015 framework elaborates on these two
aspects, subdividing knowledge
about
science into procedural and epistemic knowledge. Question
1 requires students to understand not only how the data is represented in the two graphs, but also
to consider whether this evidence scientifically justifies a given conclusion. This is one of the
features of epistemic knowledge in the 2015 framework. The context categorisation is
Environmental
– global. A new feature of the 2015 framework is consideration of cognitive demand
(see figure 23). This question requires an interpretation of graphs involving a few linked steps, and
is therefore, using the descriptors from the framework, categorised as medium cognitive demand.
