Shut up and listen to your students

Are conventional lectures the best method of teaching scientific concepts?

After all, we’ve been using the same lecture model for hundreds of years — since before books were invented. We have professors concoct their own explanations of scientific concepts, deliver them by lecture, create their own diagrams on the chalkboard, and answer student questions. Surely there must be some merit to this method, if we’ve used it for centuries.

Note that I say “scientific concepts”. I want to talk about lectures used to teach introductory physics or chemistry or mathematics, not lectures used to make people remember some facts.

The answer, of course, is “no”. Stop lecturing. Shut up and listen to your students.

Independence Day 2.0

SUPERBOWL SUNDAY, 22,000 MILES ABOVE THE EQUATOR Life as a satellite is disappointing. The first few hours are exhilarating, full of rocket blast, thrusters, and challenging equipment tests, but the average satellite soon settles into a dreary monotony. A well-designed satellite can hope for perhaps a few thruster firings or a large solar flare to


Gnome Physics

All subatomic particles — electrons, protons, neutrons and so on — are composed of extremely small gnomes. While relatively unknown, the gnome theory of matter can successfully explain many physical phenomena, including gravitation, electromagnetism, the photoelectric effect, and the wavelike properties of matter. Gravitation It is widely known that gnomes are a rambunctious species, preferring


Statistical Significance of Doom (part 2)

False positives are somewhat scarier than false negatives. What if my research claims a drug cures cancer, giving thousands of sufferers hope, but it turns out to be useless? (Before you go on, make sure you’ve read part 1 in my series on statistical significance, since it has some important detail.) If we followed the


Statistical Significance of Doom (part 1)

I was recently assigned to give a 25-minute presentation on a subject of my choice. After choosing “scientific dishonesty and fraud,” I happened upon a paper by John Ioannidis claiming that “Most Published Research Findings Are False.” After skimming through Ioannidis’ paper and reading some of the references, I quickly changed my presentation’s title to


Psychic Powers

Skeptics sometimes remark that if psychic powers were real, psychics would have a genuine evolutionary advantage, and so eventually everyone would evolve to be psychic. But we aren’t, they say, so psychic powers must not exist. It is a little-known fact that this evolution already happened. Many animals evolve mechanisms to show off to potential


Breaking News

ATLANTA — In a news conference Saturday, CNN president Ken Jautz announced that CNN’s hyperbole reserves will be empty by the end of next week. “Despite our best efforts, we have depleted our strategic hyperbole reserves and will be unable to continue news broadcasts until we can acquire further reserves,” said Jautz to gathered news


Releasing ipbLatex

At SFN, we use a custom LaTeX solution to render LaTeX equations in Invision’s IP.Board. The implementation is based on Dave’s vbLatex, which produces incredibly nice-looking equations so long as you have LaTeX installed. It also supports inline chemical equations using the mhchem package. Since we moved to IPB over vBulletin, I’ve adapted vbLatex to

I love my Kindle…

but I want a new version, with: Higher-resolution screen (200 DPI or more?) with greater contrast Full Unicode fonts (or at least handle the Euro symbol, Cyrillic and the Greek alphabet) Bigger, more responsive screen Better fonts and typography (proper small-caps, LaTeX-style justification and hyphenation algorithm, etc.) More attention paid to formatting in books and
