Research Design
Word Family Knowledge is studied in how it
relates to Overall Word Knowledge.
 Overall word knowledge is addressed with a
scale approach (Test of Academic Lexicon: TAL)
 Word Family Knowledge is addressed with a
productive derivative test (Later referred to as
Test of English Derivatives: TED)

Conclusion
• So the jump from receptive to productive
knowledge is reflected in better mastery of
productive derivative forms in each of the 4
word classes.
But
• The assumption that learners automatically
pick up the various derivative forms is
probably incorrect.
Bottom Line
To Know a Word means
to know
a great deal about it.
Derivative knowledge
cannot be taken
for granted.
