What Dick Hake's thorough investigations have shown is that k ispretty well
a constant for all levels of teacher enthusiasm. This is almostcertainly a
blow for the many of us who have approached teaching with enthusiasm andteaching. dick
have won high student evaluations and even awards for good
has provided the figures that show that all that enthusiasm, allthe spent
energy counts for very little, if for anything.
So, it seems we can drop the k from the relation. All is not lost. What
Hake has shown is that we can write.
V = scdA,
where
s = a measure of the student involvement in the learning process
c = a measure of the curriculum material used (or, the way the student's
are involved in their learning).

Thanks to the two Brians, Whatcott and McInnes, for their
thoughtful replies.
Let me comment on one aspect of Brian M's new model for the volume,
V, of student understanding. The "involvement in the learning
process" variable, s, depends heavily on HOMEWORK. Any student who
spends time at home trying to understand a text and wrestling with
interesting and challenging problems is doing true "active physics."
I'm persuaded that quality homework -- taken seriously (i.e. graded,
alas) -- may surpass even the finest lab in generating "student
involvement in the learning process."
