Fifty Years of Homework
Do students have too much homework? Do they have too little? Public opinion about homework has been contentious throughout the 20th century. However, the figure below, created by examining major national surveys over the past 50 years, shows there was no "golden age" when American students did massive amounts of homework. Except for a temporary spike in the amount of homework done during the post-Sputnik years, the trend has remained essentially flat. Today, only about one high school student in eight spends more than two hours per day on homework; that share was no higher in 1948 than it is today.
