This article conceptualises a common approach to train teachers
and university lecturers in integrating the use of e-keys produced by the
EU-funded project KeyToNature in the design, development, and delivery
of e-learning modules within their school practice. The approach is based
on setting and administering learning scenarios developed around real
practice assignments that have at their core the identification of organisms
and end up with the creation of meaningful biodiversity information products,
rooted in concrete environmental contexts. The learning products may even
include the creation of specific sub-keys from the initially used e-keys. The
paper briefly describes the application and the real testing of the approach
in an experimental teacher training course conducted in Bulgaria within the
KeyToNature project.
