In The Times this week: A video about why McDonald's, Burger King and Wendy's are facing slow growth and disgruntled employees. Note: Our Summer Reading Contest is in its ninth week, and we've been thrilled by the thousands of responses we've received since it began in June. Though we originally said that the feature would end on Aug. 16, we know that there are many students who are participating as a school assignment. For that reason, we're extending it another week, until Aug. 23 at 7 a.m. Eastern. That means that next Friday you'll be able to find one more post asking "What Interested You Most in The Times This Week?" Please note, however, that that final week will not be formally judged and no winners will be chosen, though we will choose favorites to post to our "comments of the moment" section. To participate this week, write in below. Whether it was the troubles of Alex Rodriguez, a marine mystery in Florida, the test-score declines in New York, "Burgernomics" or a unique idea for getting dog owners to clean up after their pets, tell us what you found most compelling in The Times this week, and why. Judges from Flocabulary, which is an online library of songs, videos and lessons to engage and teach students (and with whom we collaborate annually for our Year in Rap contest), will choose this week's winner (s). They will be published on Monday, Aug. 26. Michael Blankenburg is Curriculum Developer at Flocabulary Kat Lee does a little of everything at Flocabulary, and calls her role "The Wildcard."
