Each dot in the following graph represents a single content resource produced using the Book module. The book resources are organised by the year in which the relevant course was offered. The following includes data for all courses that used the Book at this university. Other pages show similar data for "unusual" courses and for a single course in which the Book resources were a core part of the learning design.
The y-axis represents the percentage of students enrolled in the course for which the book resource was produced, that read each of the chapters (pages) in the resource. This means they either visited each chapter in the resource, or they printed out the resource (the assumption being that they then read each chapter).
Roll your mouse over the box plots to see the relevant numbers.
From the graph the following can be seen:
i.e. half of the books in 2012 were completely read by less than 46.2% of the enrolled students, while half of the books in 2012 were completely read by more than 46.2% of the enrolled students.
Half of the 2015 books were completely read by less than 2% of the enrolled studnets.
