Replacing Textbooks with MOOCs

John Hawks read the article that I discussed in an earlier post [On the High Price of Textbooks]. he outlines his solution to the high cost of textbooks [Textbook troubles].

I'm building the groundwork for a project that will do something about this, at least in the area of biological anthropology. I've been following stories like this for years. Developing the MOOC, I have the tremendous opportunity to make connections with people all over the world. Most of the people signed up are nowhere near the traditional U.S. college textbook market (MOOC international enrollment numbers). I face a problem that can't be solved by textbooks today, and limited-use "rental" text that will go away at the end of the course is not a valid solution.

So I'm doing something about it. The idea has many moving parts, but at its base is the need to supply quality educational content cheaply, with a way to get articles freely outside the usual college system. I'm going to be calling for help, so keep watching this space.

This is refreshingly honest. Of the many claims about MOOCs (Massive Open Online Course), the only one that makes sense to me is to use them as a possible replacement for textbooks. They can be used as a supplemental resources in a student-centered classroom.

MOOCs are good at delivering information—the sort of information you can get from a textbook.

Now I'm waiting to see if anyone creates a MOOC that comes close to the depth and quality of university science textbooks. I imagine that it can be done but it ain't going to be cheap.

John Hawks is an expert on anthropology but I find it difficult to imagine that he's going to be able to create drawings and figures of textbook quality for no cost. I don't see how he's going to ensure high quality editing and reviewing for free. I can't imagine how he's going to mount his course on servers and provide easy access for thousands of students without incurring some costs. He's going to have to pay for permissions to use photos and figures just like the textbooks do. Maybe he'll do all the administrative work himself or maybe somebody will work for him for no salary.

It's possible to overcome all these difficulties and provide free high quality MOOCs that will replace textbooks. So far, nobody has come close in any of the subjects that I'm interested in. Most existing biochemistry MOOCs are horrible.

Holding my breath ....

On the High Price of Textbooks

Once again we have a relatively uninformed journalist writing about the high cost of college textbooks ['Required reading': As textbook prices soar, students try to cope].

I am a textbook author so I'm not totally impartial. However, it's worth pointing out that I don't defend textbooks because I'm a textbook author. Instead, I became a textbook author because I value textbooks. I still have all my college textbooks and I still refer to them from time-to-time. The oldest ones were purchased 50 years ago.

Let's look at what Martha C. White has to say.

Already grappling with skyrocketing tuition and fees, college students also must contend with triple-digit inflation on the price of textbooks. With the average student shelling out $1,200 a year just on books, students, professors and policy groups are searching for ways to circumvent the high cost of traditional textbooks.

It may be true that the average student has to spend $1200 per year on required textbooks but the NBC News Business website didn't do themselves any favors by showing a photo of 21-year-old Priya Shivraj with a stack of textbooks that she presumably had to buy in a single year. She is supposed to be a combined major in biology, Spanish and pre-med and one would guess from her age that she's in her third or fourth year of university.

Here are some of the books in her stack: Introductory Biology, Introductory Chemistry, Organic Chemistry, Introductory Biochemistry, and Immunobiology. Is it possible that a student at NYU would take all those courses in a single year?

But let's not quibble. Many science textbooks cost about $150 and I can easily imagine that a student might have to purchase as many as six of them in a single year.

The College Board found that the average student at a four-year public college spends $1,200 on “books and supplies,” or nearly $1,250 if they go to a private school. On the public policy blog of the American Enterprise Institute, where he is a fellow, University of Michigan-Flint economics professor Mark J. Perry highlighted a chart showing an 812 percent increase in the cost of college textbooks since 1978, a jump even higher than the percentage growth in the cost of health care.

This paragraph says that the "average" includes supplies and it appears to cover four years. What does that mean?

Let's use our critical thinking skills to examine the claim that textbook prices have increased by 812% since 1978. According the the US Bureau of Labor Statistics CPI Inflation Counter there should be a 358% increase in price due to inflation alone. Thus, the real cost has about doubled in 35 years.

I addressed this issue a few years ago in: PZ Rants About Science Textbooks. Here's an updated version of what I said in 2007 ...

So let's understand and agree that the original price of a textbook is not unreasonable. My biochemistry textbook in 1965 was Conn & Stumpf and it cost $9.95. This works out to $73.79 in 2013 dollars using the handy-dandy inflation calculator on the US Dept. of Labor website. The 1965 textbook was much smaller, covered less material, and had no color figures. Modern biochemistry textbooks cost about $150 and they are very much better than the books published 50 years ago.

So the price of biochemistry textbooks has doubled in constant dollars but there's a huge increase in the amount and quality of the material in modern textbooks.

Martha White continues ....

“Students are, in essence, a captive market,” said Ethan Senack, higher education associate at the U.S. Public Interest Research Group. “The publishing industry is dominated by five companies that dominate upwards of 85 percent of the market.”

“I think part of it is the consolidation… There’s less competition now,” Perry said.

This sort of complaint comes up quite often. It suggests that publishers are conspiring to keep the cost of textbooks at least twice as high as they were decades ago. It also assumes that publishers are making outrageous profits at the expense of university students. Let's use our critical thinking skills to ask whether large public companies in the publishing industry are making huge profits. Since these are public companies whose stock is trading on the stock market, it should be possible to test this idea. One of the quickest ways is to simply look at the stock prices, they should be going through the roof if the assumption is correct. They aren't. The textbook publishing industry is making a profit but it's not much different than the profits made by most other companies.

There may be lots of things wrong with making students buy textbooks but it's ridiculous to pretend that the major publishing companies are ripping off students. It's also ridiculous to pretend that the retail price paid by students at their bookstore goes directly to the publisher. The wholesale price of a $150 textbook may be only $100. The bookstores have to make money too. You can buy my book for about $110 on Amazon.

Monday's Molecule #215

Last week's molecule was malonate (propanedioic acid). A derivative of malonate called malonyl-CoA is a key intermediate in fatty acid synthesis. Bill Chaney was the first person to identify the molecule and describe its function [Monday's Molecule #214].

Recently I've been having a discussion with the Chair of my department about whether undergraduates in introductory biochemistry courses should memorize structures. He thinks they should. I wondered whether all the professors in my department could draw the structures of some important molecules. Here are a couple of molecules that you might be able to recognize. How many of you can identify them without checking a textbook?

How many of you can identify them even with a textbook? I'll need a fairly exact identification. Be sure to specify "top" and "bottom" molecules.

Email your answers to me at: Monday's Molecule #215. I'll hold off posting your answers for 24 hours. The first one with the correct answer wins. I will only post the names of people with mostly correct answers to avoid embarrassment. The winner will be treated to a free lunch.

There could be two winners. If the first correct answer isn't from an undergraduate student then I'll select a second winner from those undergraduates who post the correct answer. You will need to identify yourself as an undergraduate in order to win. (Put "undergraduate" at the bottom of your email message.)

Move This Book?

I noticed a couple of books in the Science section of my local bookstore. One was by a guy named Meyer (Stephan C. Meyer) and the other was by someone named Myers (PZ Myers). I bought the one by Myers because I already had the other one.

There are some people who get upset by seeing these books in the Science section. Some of these people even like to move them to other sections, such as religion and/or philosophy. I even did it myself on one or two occasions in the past. Lately, however, I've become somewhat less dogmatic about the creationist books. They are, after all, books about science even though they may try to bring religion into science. That does not mean their view are non-scientific. Many of those books are no worse than some of the other "science" books on the shelf that have nothing to do with religion.

What would you do? Here are the choices ...

1. Move the Meyer books to another section.
2. Move the Myers books to another section.
3. Move both books to other sections.
4. Leave both books in the Science section.

I'm especially interested in hearing from Jerry Coyne and his supporters who supported Diana MacPherson's successful attempt to get Amazon to reclassify Darwin's Doubt as a religious book [Reader gets ID book moved from science to religion section].

Amazon puts The Happy Atheist in the "Religion and Spirituality" category. Does it belong in the Science section of local bookstores?

Creationist Quotes

"Quote mining" can be fun. Here are some actual quotes taken from online forums. They are spoken by atheist actors.


Someone recently asked me why I mock creationists when I should be giving them more respect.

Sean Carroll: "What Is Science?"

I've been meaning to comment on Sean Carroll's post from last July (July 3, 2013) but there always seems to be something else that commands my attention. The issue is important, in fact I've just finished an entire book on the question (Philosophy of Pseudoscience: Reconsidering the Demarcation Problem edited by M. Pigliucci and M. Boudry).

Sean Carroll (the physicist)¹ has a view that's quite similar to my own. Read his post at: What Is Science?. Here are some key points.

Better Biochemistry: Teaching ATP Hydrolysis for the MCAT

I'm digesting the idea that many American biochemistry courses teach to the MCAT exam [see Better Biochemistry: Teaching to the MCAT?]. What this means is that the scientists who teach biochemistry are willing to let the curriculum be established by a group of American medical schools (AAMC). That organization has put up a website to guide faculty members and students in preparation for the 2015 MCAT exam [MCAT2015: Biological and Biochemical Foundations of Living Systems].

One of the links takes you to a chemwiki at the University of California, Davis: Biological Chemistry. From there you can click on several topics. I picked ATP/ADP to see what kind of information the MCAT thinks is appropriate. The information on the ATP website is provided by Tiffany Lui of the University of California, Davis so it's not something that AAMC created. Nevertheless, it is presumably indicative of the sort of thing that might appear on the MCAT exam.

Humans Are Still Evolving

Sir David Attenborough said something stupid the other day [Sir David Attenborough: Humans have stopped evolving]. (Not for the first time.) He said ...

Because if natural selection, as proposed by Darwin, is the main mechanism of evolution – there may be other things, but it does look as though that’s the case – then we’ve stopped natural selection.

We stopped natural selection as soon as we started being able to rear 95–99 per cent of our babies that are born.

We are the only species to have put a halt to natural selection, of its own free will, as it were.

The headline says that humans have stopped evolving. If that's what he really said then it's easy to prove him wrong by showing that there's a lot more to evolution than natural selection [Have Humans Stopped Evolving?].

But what about his specific claim that natural selection doesn't work on humans any more? I covered that in earlier posts but John Hawks has corrected him today [Humans are still evolving, and soon we'll know a lot more about it]. I love it when I agree with John Hawks! (That's me, visiting him in his lab in Madison, Wisconsin.)

Better Biochemistry: Teaching to the MCAT?

Theme

Better BiochemistryI view science education as a way of teaching students how to think critically. In that sense, it's not any different than education in the arts and humanities. In my opinion, biochemistry should be taught as a bunch of fundamental concepts and principles that will help students understand the basics of life at the molecular level. The course will demonstrate how to think critically and how we come to know what we know—if we teach it correctly. I believe that biochemistry should be taught from an evolutionary perspective since that's the best way to achieve fundamental understanding.

The last thing we should be doing in an undergraduate biochemistry course is to ask students to memorize enzymes, structures, and pathways and regurgitate them on an exam. We should not just be teaching the biochemistry of humans since that does not provide students with a broad view of life and where humans came from. Such an approach also makes biochemistry seem like it's only important because it can contribute to health. We have plenty of evidence that this is the wrong way to teach.

The Happiest Countries

Why do the people of these countries think they are happy? Why isn't the USA in the top ten? [World’s Happiest Countries In 2013, According To The UN]

I recently visited #1, #2, #5, #7 and #9 and I can confirm that the citizens of those countries do, indeed, think they are happy. I also visited #17 a few months ago and the citizens of that country do not seem happy. It's probably worse today than it was a few months ago.

Science and Mystery

One of the criticisms of science (narrow definition) is that its reductionist approach is simplistic and materialistic. Here's how Jesus and Mo dealt with that issue last month.

What Is "Science" According to George Orwell?

I'm about to start teaching my course on "Scientific Misconceptions" and one of the most important issues is defining science and dealing with the demarcation problem. Vincent Joseph Torley is also interested in this question—for a different reason—and he discovered an 1945 essay by George Orwell (Eric Arthur Blair (1903-1950)).

It's worth quoting the relevant passages.
Doublethink means the power of holding two contradictory beliefs in one's mind simultaneously and accepting both of them.

George Orwell

In last week’s Tribune, there was an interesting letter from Mr. J. Stewart Cook, in which he suggested that the best way of avoiding the danger of a “scientific hierarchy” would be to see to it that every member of the general public was, as far as possible, scientifically educated. At the same time, scientists should be brought out of their isolation and encouraged to take a greater part in politics and administration.

As a general statement, I think most of us would agree with this, but I notice that, as usual, Mr. Cook does not define Science, and merely implies in passing that it means certain exact sciences whose experiments can be made under laboratory conditions. Thus, adult education tends “to neglect scientific studies in favour of literary, economic and social subjects”, economics and sociology not being regarded as branches of Science, apparently. This point is of great importance. For the word Science is at present used in at least two meanings, and the whole question of scientific education is obscured by the current tendency to dodge from one meaning to the other.

Science is generally taken as meaning either (a) the exact sciences, such as chemistry, physics, etc., or (b) a method of thought which obtains verifiable results by reasoning logically from observed fact.

If you ask any scientist, or indeed almost any educated person, “What is Science?” you are likely to get an answer approximating to (b). In everyday life, however, both in speaking and in writing, when people say “Science” they mean (a). Science means something that happens in a laboratory: the very word calls up a picture of graphs, test-tubes, balances, Bunsen burners, microscopes. A biologist, and astronomer, perhaps a psychologist or a mathematician is described as a “man of Science”: no one would think of applying this term to a statesman, a poet, a journalist or even a philosopher. And those who tell us that the young must be scientifically educated mean, almost invariably, that they should be taught more about radioactivity, or the stars, or the physiology or their own bodies, rather than that they should be taught to think more exactly.

Every war when it comes, or before it comes, is represented not as a war but as an act of self-defense against a homicidal maniac.

George OrwellI agree with Orwell when he prefers the broad definition of science. I see it as a way of knowing that can be applied to any discipline. I think that everyone should become more scientifically literate but by that I don't mean they should lean more about metabolic pathways or quantum chromodynamics. I mean that they should become more familiar with the scientific approach to acquiring knowledge. That's the fundamental skill that we need to learn.

Clearly, scientific education ought to mean the implanting of a rational, sceptical, experimental habit of mind. It ought to mean acquiring a method – a method that can be used on any problem that one meets – and not simply piling up a lot of facts. Put it in those words, and the apologist of scientific education will usually agree. Press him further, ask him to particularise, and somehow it always turns out that scientific education means more attention to the sciences, in other words – more facts. The idea that Science means a way of looking at the world, and not simply a body of knowledge, is in practice strongly resisted. I think sheer professional jealousy is part of the reason for this. For if Science is simply a method or an attitude, so that anyone whose thought-processes are sufficiently rational can in some sense be described as a scientist – what then becomes of the enormous prestige now enjoyed by the chemist, the physicist, etc. and his claim to be somehow wiser than the rest of us?

A hundred years ago, Charles Kingsley described Science as “making nasty smells in a laboratory”. A year or two ago a young industrial chemist informed me, smugly, that he “could not see what was the use of poetry”. So the pendulum swings to and fro, but it does not seem to me that one attitude is any better than the other. At the moment, Science is on the upgrade, and so we hear, quite rightly, the claim that the masses should be scientifically educated: we do not hear, as we ought, the counter-claim that the scientists themselves would benefit by a little education. Just before writing this, I saw in an American magazine the statement that a number of British and American physicists refused from the start to do research on the atomic bomb, well knowing what use would be made of it. Here you have a group of sane men in the middle of a world of lunatics. And though no names were published, I think it would be a safe guess that all of them were people with some kind of general cultural background, some acquaintance with history or literature or the arts – in short, people whose interests were not, in the current sense of the word, purely scientific.

Where did the George Orwells of this world go? Why don't we have more people like him today? Have they just been drowned out by idiots with access to a microphone?

Irony Upon Irony

For those (few) of you who are interested in the pathology of IDiots, you have to read Irony of the Day. It's posted on Uncommon Descent and the author is Barry Arrington.

This is a satirical summary of his point.

Many skeptics say that the Flying Spaghetti Monster is imaginary. However, it's impossible to prove that the Flying Spaghetti Monster doesn't exist. Even Richard Dawkins says that you can't prove a negative.

Therefore, when you say that the Flying Spaghetti Monster is imaginary, you aren't being a true skeptic. Instead, you are expressing "uncritical arrogant dogmatism that would make the most committed fundamentalist blush. And that, my friends, is the irony of the day."

You can't make this stuff up.

Reviews of Darwin's Doubt: Keeping Score

Several scientists have reviewed Stephen Meyer's latest attack on science [see Slaying Meyer’s Hopeless Monster]. Don't think the IDiots haven't noticed ... they've responded to several specific criticisms (and ignored others).

I know it's hard to keep score so David Klinghoffer has done it for us in: More Evidence of Darwinian Short-Term Memory Loss.

As far as I'm aware, no reviewer has yet genuinely laid a hand on "Darwin's Doubt," not for lack of trying. Well, there's always tomorrow.

The IDiots are learning to master the basic skills of propaganda and they're doing a pretty good job. For example, here's a video promotion of Darwin's Doubt. See if you can recognize the lies, the tricks and the deceptions.

Monday's Molecule #214

Last week's molecule was 6-phosphogluconate, the second intermediate in the pentose phosphate pathway. Nobody got the right answer! [Monday's Molecule #213].

Classes have now started at most universities in North America so let's celebrate by picking a very simple molecule—one that most undergraduates should recognize if they've taken a biochemistry course. Derivatives of this molecule are essential components of several fundamental pathways; which ones? Give me the common name and the official IUPAC name.

Email your answers to me at: Monday's Molecule #214. I'll hold off posting your answers for 24 hours. The first one with the correct answer wins. I will only post the names of people with mostly correct answers to avoid embarrassment. The winner will be treated to a free lunch.

There could be two winners. If the first correct answer isn't from an undergraduate student then I'll select a second winner from those undergraduates who post the correct answer. You will need to identify yourself as an undergraduate in order to win. (Put "undergraduate" at the bottom of your email message.)
