WTCD

WTCD is a flexible, multi-functional vocabulary teaching system. It provides material that teachers can either use as-is (i.e. ready prepared) or adapt to supplement their own teaching materials.
WTCD contains prepared vocabulary lessons based on the vocabulary from mainstream course books, like Cutting Edge, New Headway, Lifelines, Project Oxford, Opportunities and Streamline English, as well as other sources, like books and novels.
