Most of us develop a sort of intuitive logic about how the natural world works. Unfortunately, a lot of that informal reasoning turns out to be wrong, which complicates scientific education. But as students make their way through the science education pipeline, they should gradually start moving beyond the informal reasoning of their earlier years. Or at least that's what we'd like to think; instead, a new survey of college students, some in advanced biology classes, indicates that most end up with a confused mix of formal and informal reasoning. ...
The end result, the authors conclude, is that "faculty are unknowingly speaking a different language from their students." They think that when they mention lost energy, the students know what they're talking about, or that their students' poor choice of wording doesn't represent a failure of logic. As a result, they see little reason to speak more carefully or devote instructional time to clearing up misconceptions. And, even if they wanted to, most biology textbooks consider principle-based reasoning beyond their scope.

Please pick a handle or moniker for your comment. It's much easier to address someone by a name or pseudonym than simply "hey you". I have the option of requiring a "hard" identity, but I don't want to turn that on... yet.
With few exceptions, I will not respond or reply to anonymous comments, and I may delete them. I keep a copy of all comments; if you want the text of your comment to repost with something vaguely resembling an identity, email me.
No spam, pr0n, commercial advertising, insanity, lies, repetition or off-topic comments. Creationists, Global Warming deniers, anti-vaxers, Randians, and Libertarians are automatically presumed to be idiots; Christians and Muslims might get the benefit of the doubt, if I'm in a good mood.
See the Debate Flowchart for some basic rules.
Sourced factual corrections are always published and acknowledged.
I will respond or not respond to comments as the mood takes me. See my latest comment policy for details. I am not a pseudonomous-American: my real name is Larry.
Comments may be moderated from time to time. When I do moderate comments, anonymous comments are far more likely to be rejected.
I've already answered some typical comments.
I have jqMath enabled for the blog. If you have a dollar sign (\$) in your comment, put a \\ in front of it: \\\$, unless you want to include a formula in your comment.
