OER report 2023
Get PDFThe course for which I am developing OERs is BIOL 3425 Functional Anatomy, a large lecture and lab course (~70 students). The expensive cost of the textbook I previously used (Kardong (2018) Vertebrates: Comparative Anatomy, Function, Evolution, 8th Edition. McGraw Hill) seemed to preclude some students from purchasing it and preparing adequately to succeed in class. The cost of a new hardcover textbook is 10,850 by using an OER as a substitute. There are four OER components to the course I have developed

Get PDFModule 13: Improving Short-Term Memory
It should be clear that short-term memory has limits, but those limits are flexible. This has been demonstrated in the studies described earlier in the chapter, but there are also more concrete examples of how the boundaries of memory can be pushed.
In 2013, Simon Reinhard sat in front of 60 people in a room at Washington University, where he memorized an increasingly long series of digits. On the first round, a computer generated 10 random digits—6 1 9 4 8 5 6 3 7 1—on a screen for 10 seconds. After the series disappeared, Simon typed them into his computer. His recollection was perfect. In the next phase, 20 digits appeared on the screen for 20 seconds. Again, Simon got them all correct. No one in the audience (mostly professors, graduate students, and undergraduate students) could recall the 20 digits perfectly. Then came 30 digits, studied for 30 seconds; once again, Simon didn’t misplace even a single digit. For a final trial, 50 digits appeared on the screen for 50 seconds, and again, Simon got them all right. In fact, Simon would have been happy to keep going. His record in this task—called “forward digit span”—is 240 digits!
When most of us witness a performance like that of Simon Reinhard, we think one of two things: First, maybe he’s cheating somehow (he is not, by the way). Second, Simon must have abilities more advanced than the rest of humankind. After all, psychologists established many years ago that the normal memory span for adults is about 7 digits, with some of us able to recall a few more and others a few less (Miller, 1956). That is why the first phone numbers were limited to 7 digits—psychologists determined that many errors occurred (costing the phone company money) when the number was increased to even 8 digits. But in normal testing, no one gets 50 digits correct in a row, much less 240. So, does Simon Reinhard simply have a photographic memory? He does not. Instead, Simon has taught himself simple strategies for remembering that have greatly increased his capacity for remembering virtually any type of material—digits, words, faces and names, poetry, historical dates, and so on. Twelve years earlier, before he started training his memory abilities, he had a digit span of 7, just like most of us. Simon has been training his abilities for about 10 years as of this writing and has risen to be in the top two of “memory athletes.” In 2012, he came in second place in the World Memory Championships (composed of 11 tasks), held in London. He currently ranks second in the world, behind another German competitor, Johannes Mallow
