To illustrate the different, let us compare the way two separate biology courses handle the same laboratory lesson-that of the classic microscopic examination of cork, first performed by Robert Hooke in 1665 and presented in Biology Investigations [12] and in Biological Science: An Inquiry Into Life [2]. While both presentations feature elements of inquiry to some degree, the first may be classified generally as a traditional approach, while the second is an example of the inquiry method.
