The Strength and Evidence for FVR - Krashen
"The most important question one can ask about any reading activitiy is whether it helps create a lifelong reader (Calkins, 2004). Results from SSR are encouraging!"
Stephen Krashen makes a series of statements about FVR that are are supported by research evidence. (Those that are supported only in anecdotal reports are marked with an asterisk *.) This list begins with research on free voluntary reading done in a school setting, aka Sustained Silent Reading (SSR). In SSR, time is set aside for recreational reading; students read whatever they like (within reason), and are not tested on what they read.
