People on imdb have a bad habit of giving movies they think are overrated 1s, or movies they think are underrated 10s. This movie is an example of the former.

I returned to another OER Learning Circle and wrote an ebook version of a Modern World History textbook. As I wrote this, I tested it out on my students. I taught them to use the annotation app, Hypothesis, and assigned them to highlight and comment on the chapters each week in preparation for class discussions. This had the dual benefits of engaging them with the content, and also indicating to me which parts of the text were working well and which needed improvement. Since I wasn't telling them what they had to highlight and respond to, I was able to see what elements caught students attention and interest. And possibly more important, I was able to "mind the gaps', and rework parts that were too confusing or too boring to get the attention I thought they deserved.

+1 to counter the drive-by downvote. I'd still use sed for this, unless you need the power of Perl regular expressions to select the delimiting lines
