There are, however, at this stage more questions than answers. For example, is the inability
of some learners to engage in argumentation and move beyond level one linked to their
knowledge levels, or whether providing apparatus and allowing the learners to perform the
experiment themselves would have any impact on the argumentation process. But it seems
reasonable to suggest that the approach is worthy of further investigation in the context of the
South African curriculum (and most modern curricula) and may be important in terms of formulating
effective teacher development strategies to embed the approach within a culture of
scientific literacy.
