Late Night Cramming is Harmful

July 9, 2019

This post is motivated by programs showing students cramming for tests. The scenario is that such demands are being placed on these students for success that they are working extremely hard. Should these stories be true, then not only are these students risking their health, but there is a limit on how much study can been done effectively. Beyond this, they are spinning their wheels, not enhancing their knowledge, and risking their health.

Consider placement tests like the ACT and the SAT. There has been some research showing some benefits of preparing for these tests. What is needed is further research in which the students log not only the time studying was done, but also the time of day the studying was done. HM would predict that there is some benefit, but this benefit would max out and additional time might even be harmful (scores would decline). The time at which the studying was done should also be studied. HM predicts that little would be gained for studying at late hours and that there even might be some decrement. After all, presumably these tests are supposed to measure aptitude. If this is true, there should be limits on the amount of benefit.

These programs also portray students at prestigious universities cramming and putting in late hours preparing for tests. HM attended state universities and saw this same phenomena. The reason these students were cramming and pulling late or all-nighters was that they did not keep up with the work. They were cramming in an attempt to catch up.

HM strongly suspects that this is also the case at prestigious universities. If these universities do require excessive workloads, then prestigious university or not, students should withdraw from the school and their parents should encourage them to withdraw, because the instruction is harming, not benefiting, the students.

Learning requires cognitive effort, which can be exhausted. When this cognitive effort is exhausted little learning takes place. Sleep is also essential. Memories are consolidated during sleep. So studies pulling all nighters are cheating themselves of their memories consolidating. In other words, the all-nighter is harmful, not beneficial.

In the military sometimes military personnel must push themselves to operate long hours with little or no sleep. Unfortunately, this is a reality of military operations and requires training to be prepared for these operations. However, for normal instruction to be effective, students need their sleep. There have been studies on trainees that have shown when trainees are allowed to get their necessary sleep, their learning and performance on tests improve. So for regular training, planning should include regular sleep, but there will need to be training for prolonged operations that should be done separately. Actually, what is being learned during training for these prolonged operations is how to compensate for degraded performance when the body is fatigued and crying for sleep.

Goodbye SAT

April 8, 2015

“Goodbye SAT:  How online courses will change college admissions,” is an opinion piece by Kevin Carey in the March 19th Washington Post.  He makes a good case for the SAT either becoming absolute or a rather minor factor in college admissions decisions.  He cites research by economist Jesse Rothstein who found that, after controlling for student’s background characteristics, SAT scores predict only 2.7 percent of the variation in students’ college grades.

Through a nonprofit consortium called edX, Harvard, MIT, the University of Texas, the University of California at Berkeley, Columbia, Dartmouth, Cornell, Caltech, the Sorbonne and dozens of other elite universities offer complete online versions of their classes, free, to anyone with an Internet connection.  Topics include computer science, matrix algebra, poetry and Chinese History from Harvard; engineering, mathematics and jazz appreciation from UT;principles of economics and data analysis from Caltech.  edX is  not alone, there are other online education platforms such as Coursera, that offer thousands of additional courses from elite universities, free.  These can be the same courses offered in college courses, to include lectures, homework assignments, midterms and final exams.  Although the courses are free, the degrees are not, but more about that later.

Prospective students can build an impressive transcript before they formally enter college  This also provides a good opportunity to learn how much they like and how well they fit into different subjects.  Success in these Massive Online Open Courses (MOOCs) are much more likely to predict success in college classes than SAT scores, because they are courses in college.

Here are some outstanding examples cited in Carey’s article.  In 2012 when he was 15, living in Bator, Mongolia taking online course from MIT was one of only 340 students out of 150,000 worldwide to earn a perfect score in a rigorous online Circuits and Electronics course.  He’s currently enrolled at MIT.  Another student from the same class, Amol Bhave from Jabalpur, India, enjoyed the class so much that he created his own online follow-up course in signals and systems.  He was also admitted to the 2013 MIT freshman class.

If they are not already, colleges are likely to charge for certificates of completion as well as transcripts.  And it is likely that universities will recognize these courses in satisfying the requirements ford different degrees.  It is also likely that some residency requirement will be required by many schools.  Nevertheless, MOOCS offer welcome degrees of freedom in earning degrees.  And this definitely should have a positive impact on reducing the current ridiculous costs of degrees.

MOOCS are already ideal for autodidacts.  They are also ideal for older individuals who want to keep sharp and grow cognitively.  sYou can become an expert in a field, start on the road to fulfillment  and simply bypass formal degrees.  In my personal experience, I’ve found degrees to be an unreliable indication of a knowledgeable individual.  I remain incredulous that many people I know who have college degrees actually have college degrees.  I know of people with graduate degrees who don’t seem to be able to write coherently.  Seeing a transcript with courses and grades would be much more informative than a degree.
