prepared for discussion with one of my classes. On my later
examination of this problem I was much surprised, both at its
difficulty and scope, and also at the extent to which it had been
neglected by teachers. Ever since that time the two questions, How
adults should study, and How children should be taught to study, have
together been my chief hobby.

The following ideas are partly the result of reading; but since there
is a meagre quantity of literature bearing on this general theme, they
are largely the result of observation, experiment, and discussion with
my students. Many of the latter will recognize their own contributions
in these pages, for I have endeavored to preserve and use every good
suggestion that came from them; and I am glad to acknowledge here my
indebtedness to them.

In addition I must express my thanks for valuable criticisms to my
colleague, Dr. George D. Strayer, and also to Dr. Lida B. Earhart,
whose suggestive monograph on the same general subject has just
preceded this publication.
