The amount that students read for enjoyment and for school is a major contr
ibutor to students' reading achievement and knowledge of the world. Consequ
ently, it is important to identify the factors that predict amount of readi
ng. A literature review revealed that motivation, strategy-use, and past re
ading achievement all may be expected to predict reading amount. To examine
these variables, a total of 251 students in Grades 3 and 5 was administere
d questionnaires of these constructs and a reading test. Results showed tha
t amount of reading for enjoyment was predicted most highly by motivation,
when all other variables were controlled statistically in multiple-regressi
on analyses. In contrast, amount of reading for school was predicted most h
ighly by strategy use, when all other variables were controlled. However, t
hese predictions were different for students in Grades 3 and 5. Findings of
the study indicate that amount of reading is multiply determined by cognit
ive and motivational constructs, which is consistent with an engagement per
spective on reading development. (C) 2001 Academic Press.
