Somewhat surprisingly, there is very little research about the amount of time it takes the average college student to complete common academic tasks. We have self-reported estimates of how much total time they spend on academic work outside of class (12-15 hours), but we don’t know much about the quality and quantity of the work that is produced in that time frame (let alone how the time is allocated to different tasks). We also know quite a bit about how students tackle common academic tasks, but those studies rarely ask students to report on how long it takes them to complete the task (whether reading a book, writing a paper, or studying for an exam). The testing literature provides some clues (because valid instrument design depends on data about the average speed of test takers), but it’s tough to generalize from the experience of taking high-stakes, timed tests to the experience of working on an assignment in the comfort of your dorm. And while there is a sizable literature on reading, the nature and purpose of the reading tasks in these experiments are also quite different from what students typically encounter in college.
All of which is to say the estimates above are just that: estimates.
To arrive at our estimates, we began with what we knew from the literature and then filled in the gaps by making a few key assumptions. The details of our calculations are below. If you still find our assumptions unreasonable, however, the estimator allows you to manually adjust our estimated rates. We also welcome those who have knowledge of research about which we are unaware to suggest improvements.
Of all the work students might do outside of class, we know the most about their reading. Educators, cognitive psychologists, and linguists have been studying how human beings read for more than a century. One of the best summaries of this extensive literature is the the late Keith Rayner’s recently published “So Much to Read, So Little Time: How Do We Read, and Can Speed Reading Help?” A central insight of this piece (along with the literature it summarizes) is that none of us read at a constant rate. Instead, we use varying rates that depend on the difficulty and purpose of the reading task (Rayner et al., 2016; Love, 2012; Aronson, 1983; Carver, 1983, 1992; Jay and Dahl, 1975; Parker, 1962; Carrillo and Sheldon, 1952; Robinson, 1941). Another obvious (but rarely acknowledged) insight is that a page-based reading rate is going to vary by the number of words on the page. As a result, our estimator assumes that reading rate will be a function of three factors: 1) page density, 2) text difficulty, and 3) reading purpose. For the sake of simplicity, we limited the variation within each factor to three levels.
*estimates were determined by direct sampling of texts in our personal collection
What we know from the research:
What we don’t know, but deduce and/or stipulate:
Sadly, we know much less about student writing rates than we do about reading rates. This is no doubt because writing rates vary even more widely than reading rates. Nevertheless, we’ve found at least one study that can give us a place to begin. In “Individual Differences in Undergraduate Essay-Writing Strategies,” Mark Torrance and his colleagues find (among other things) that 493 students reported spending anywhere between 9 to 15 hours on 1500-word essays. In these essays, students were asked to produce a “critical description and discussion of psychological themes” using at least one outside source. Torrance and his colleagues also show that students who spent the least time reported no drafting, while those who spent the most time reported multiple drafts, along with detailed outlining and planning. And the students who spent the most time received higher marks than those who spent the least (Torrance et al., 2000).
Although the sample of this study is sizable, we should not read too much into a single result of student self-reports about a single assignment from a single institution. But to arrive at our estimates, we must. Users should simply be aware that the table below is far more speculative than our reading rate estimates. And that the time your students spend on these tasks is likely to vary from these estimates in significant ways.
As with reading rates, we assume that writing rates will be a function of a variety of factors. The three we take into account are 1) page density, 2) text genre, 3) degree of drafting and revision.
