How Much Assigned Reading is Too Much or Too Little?

This week’s tip focuses on the question of how much reading to assign. Is generally accepted that on average students should spend two hours out of class time engaging the course materials for every hour of in-class time.  For a student taking five classes that each meet three hours a week, this means that students would spend 30 hours each week outside of class engaged in course work, reading, reviewing, solving problems etc.  It is worth noting that this adds to 45 hours per weeks for university academic work, which is than more a full time job.  However, the reality is that university students spend on average 14 or 15 hours a week outside of class on academic work and often less especially if they are working part-time.  For effective teaching and learning, student and teacher expectations need to be in reasonable alignment.  Since one of the most common academic activities students do is assigned reading it is worthwhile to consider how much reading to assign. 

Recently the Center for Teaching Excellence at Rice University developed an interactive  website “How Much Should We Assign? Estimating Out of Class Workload”to assist faculty in estimating class workload.  They looked at both reading and writing. The reading workload estimator takes into account the words per page (wwp), the difficulty of the material, and the academic purpose.  Reading speed is a function wpp, the difficulty of the content, the academic purpose and the background knowledge of the reader.  Assigned readings can have different academic purposes from raising awareness (scanning), to increasing understanding, to critical engagement e.g. deep/critical reading. The purpose effects the number of pages per hour (pph) student reading speed.  The site does not take into consideration language ability, something that is critical for institutions where the lingua franca, language of instruction, is not students’ native language.  The site provides reading hour calculation guide lines based on published reading rates.  For example, the average adult reading rate is 30 pph and student reading rate is 20 pph for general reading materials such as a book or magazine article.  Of course individual reading rates vary and academics vary their reading rates both within a reading and the across reading types.  As seasoned readers we know what parts to skip, what can be skimmed, where to slow down and what to focus on.  Many undergraduate and beginning graduate student read assigned readings at the same pace irrespective of purpose or difficulty. 


The graphic below shows the estimated pph reading times for a typical monograph or book with 600 wpp.  As one can see if the reading purpose it to simply survey for key ideas then on average, students can survey/skim a 50-page article in an hour if there are no new words or concepts.  This drops to 25 pages per hour if there are many new words or concepts.  However, if the purpose is to critically read, question, reflect and analyze the pph rates drop to 13 hour if there are no new words of concepts and 7 or less if there are many new words or concepts.  If the reading is low word density text such as a 6X9 paperback then the pph rate increase by a factor of 1.3.  For example, if the assignment was as 100-page paperback with no new concepts or words with an estimated reading speed of 37 pph or the workload would be approximately 3 hrs. If the assignment was to read 40 pages of academic reading (600wwp) for understanding and the material contained some new concepts or words estimated reading speed is 18 pph and this would require approximately 2.2 hrs. of workload time.  If the assigned material is an academic journal article (750 wpp) and the purpose is to the engage material that includes some new concepts or words then the estimated reading workload time would be 1.4 hrs. for a 10-page article.  The Rice CTE site provides a convenient table and interactive tool for estimating reading workload time.

These rates are based on students reading material in their native language.  If they are reading material in a second language the rates will drop depending on their second language skill level.  For students who are at an intermediate level the rates will likely drop by 50 percent and for beginner level students even more and the workload times would increase accordingly.

 Of course these are at best soft estimates and different materials have different wpp and different levels of difficulty and individual students have different levels of reading and language ability.  None-the-less it is worthwhile to occasionally step back and estimate the assigned readings workload.  Is it too little?  Or so much that only the most dedicated students will do it?  For courses that use discussion pedagogy if students have not done the reading it makes for a frustrating and difficult class.  The adage “Less is More” may be useful in ensuring that students actually do the reading.  In the comment box can you share your expectations on what is reasonable assigned reading load for your class?
