When used thoughtfully, book logs can provide a window into the reading life of a kid. A book log can help make invisible qualities visible: a kids’ level of engagement, volume (amount) of reading, as well as the types of books the reader enjoys. Recording the time can reveal stamina (reading for extended periods of time), as well as home/school reading habits.
Book logs might only be used at pivotal points in the year, to get to know kids and help them build a reading life for themselves. Beyond that, book logs become a tool that some might find helpful, and others might not.
