Scientific enquiry is another construct that has been extensively used in didactics
of science. Flick and Lederman (2004), for instance, have been pointed out that
enquiry and NOS are intimately related, and yet conceptually separable. In the
nature of ‘whole science’ approach adopted here, scientific enquiry is used more or
less as a synonym of scientific investigation. In fact, enquiry, just as investigation,
can be suggestively conceptualised as an evidence-related construct; the noun
‘enquiry’ comes from the Latin verb ‘inquaerere’, with the meaning of seek or ask.
