Knowing the parts of a neuron isn't really that important
I recently had the conversation below with a high school science teacher (and, yes, I did it respectfully for those of you who are wondering)...
I want my students to learn the parts of a neuron.
In an era of near-instant Internet search, it's possible that knowing the parts of a neuron isn't really that important. For example, if I don't know what the parts of a neuron are, I probably can find a couple dozen images of neurons - with parts labeled - in about 5 seconds using an online image search engine. It seems to me that what's more important is generally knowing what neurons are, how they work, why I should care about them, how they impact my health and well-being, how current cutting-edge neurological research may impact me in the future, and so on.
Will I need to learn the parts of a neuron in the short term so that I can understand these bigger issues? Yes, most likely. Six weeks from now, will it be important if I still remember the parts of a neuron? Probably not, because I always can look it up again. But the bigger-picture understandings about neurons and how they impact me? That's what I need to remember six weeks from now - and six years from now. That's the stuff that's important. Assess on what's important.
What do you think? Would you have responded differently than I did?

You can say 'no' to things, and you should. Do it like this.
- Give yourself permission to say "no" to things. Saying yes to everything is a fast way to burn out.
- Learn to say no in a way that keeps the door of opportunity open: No should never be a one-word answer. Say "No, but I could do this instead," or, "No, but let me connect you to someone who can help."
- If you really want to say yes but can't manage another commitment, try qualifiers like "yes, if," or "yes, after."
Three scientists publish a paper proving that Mercury, not Venus, is the closest planet to Earth.
- Earth is the third planet from the Sun, so our closest neighbor must be planet two or four, right?
- Wrong! Neither Venus nor Mars is the right answer.
- Three scientists ran the numbers. In this YouTube video, one of them explains why our nearest neighbor is... Mercury!
Neuroscience research suggests it might be time to rethink our ideas about when exactly a child becomes an adult.
- Research suggests that most human brains take about 25 years to develop, though these rates can vary among men and women, and among individuals.
- Although the human brain matures in size during adolescence, important developments within the prefrontal cortex and other regions still take pace well into one's 20s.
- The findings raise complex ethical questions about the way our criminal justice systems punishes criminals in their late teens and early 20s.
