Getting students to do their assigned reading is a struggle. Most teachers don't need anyone to tell them what the research pretty consistently reports. On any given day, only 20 to 30 percent of the students arrive at class having done the reading. Faculty are using a variety of approaches to up that percentage: quizzes (announced, unannounced, online), assignments that require some sort of written response to the reading, reading journals, a variety of optional reading support materials, and calling on students to answer questions about the reading. Which of these approaches work best?
