Course: Introduction to Forensic Science (8 weeks)
School: Nanyang Technological University, Singapore via Coursera (free)
Instructors: Roderick Bates, Associate Professor of Chemistry
Quote:This course aims to help everyone understand more on how basic scientific principles underpin Forensic Science and can contribute to solving criminal cases.
Some questions which we will attempt to address include:
• How did forensics come about? What is the role of forensics in police work? Can these methods be used in non-criminal areas?
• Blood. What is it? How can traces of blood be found and used in evidence?
• Is DNA chemistry really so powerful?
• What happens (biologically and chemically) if someone tries to poison me? What happens if I try to poison myself?
• How can we tell how long someone has been dead? What if they have been dead for a really long time?
• Can a little piece of a carpet fluff, or a single hair, convict someone?
• Was Emperor Napoleon murdered by the perfidious British, or killed by his wallpaper?
[addendum: Coursera has converted this course to their new platform; content may have changed, and the experience may be very different]
Have you read the collected works of Kathy Reichs and Patricia Cornwell? Know every episode of CSI, L&O, and Quincy by heart? (Ok, I’m really dating myself with that last one) Do you have Halpern’s 1979 primer on the New York City OCME, or a complete set of Baden’s publishings? If so, you might find yourself overprepared for most of this class, but the analytical chemistry in the second week might make it worth your while anyway.
A look at the topics might give you some idea of just how superficially they were covered: fingerprinting, fibers, and firearms appeared in a single week (a little more than an hour in lectures, plus some short case overviews), as did time of death calculations and everything you wanted to know about blood, from typing to spatter patterns. It is of course an introductory course of only eight weeks duration, so only so much depth and detail can be expected.
Lectures on weekly topics were punctuated with several abbreviated descriptions of actual cases of forensic science at work: the unearthing of King Richard III, the murder of JonBenét Ramsey, Wayne Williams’ capture, and Alexander Litvinenko’s bizarre assassination, as well as a host of lesser-known victims and assailants. Again, I found these quite superficial, but I’m weird.
Assignments that counted towards the final grade had a varied format. Most weeks included a one-question “opinion poll” intended to be completed before viewing the lectures, as a way of priming the material. Three multiple-choice quizzes appeared at intervals, about 20 questions in length with two tries allowed. And then there was the dreaded Peer Assessment: two case analyses. I was impressed that the first of these was more of a practice run, as it counted very little towards the final grade but gave us a chance to see what was expected. A weightier case analysis served as a sort of final exam, though some technical issues raised concerns (as usual, I’m writing this before I have any idea what my grade is; I expect to “pass” but who knows with peer assessment).
Considering the drama of the video graphics – imagine that bloody handprint punctuated by pounding bass and drums – it was a remarkably bland class. There were some attempts at humor, but most of them fell rather flat. As always, I criticize reluctantly, since it’s a course offered for free, and I’m sure there are students for whom it’s the perfect class. I just can’t work up a lot of enthusiasm. Yet, I completed the course, and considering I drop courses pretty easily these days, that says something.
