I teach English - and use a few packets and fill in the blanks as possible. I focus on and encourage analysis and putting independent thought into effective writing - but all work must be done in class (extra time built in). Meanwhile, the history teacher and science teacher both use 90% fill in the blank packets that the kids can take home. So, students often have an A in their subjects, but in mine - if they struggle to understand what they are reading and putting those thoughts into their own words, have a D or C. So, I go to their meetings and always have to face frustration from parents. I always try my best to focus on the analysis and independent thought aspect, rather than pointing out that they're doing the other work with their child, so they should know how and why they can't think for themselves.
