The handwriting teacher who arrives in a classroom with a box of sharpened pencils is making, among other things, a statement about what kind of learning she believes will happen in her classroom that day. The pencil — its particular resistance, the way it requires periodic sharpening, the faint ghost of its mark that persists on the page below when you erase it — produces a different cognitive and physical relationship with writing than a keyboard does.

The debate about handwriting's place in contemporary education has been sharpened by neuroscience research showing that the physical act of forming letters activates broader neural networks than typing the same letters on a keyboard. Students who take notes by hand remember the material better than those who type the same notes, an effect attributed partly to the slower pace of handwriting forcing a processing and compression of information that typing — which can be fast enough to transcribe almost verbatim — does not require.

The standardized test context that the "2B or not 2B" question implicitly invokes is where pencil instruction remains most practically consequential. The standardized testing infrastructure of most countries' educational systems — where millions of answer sheets are machine-read from pencil marks — creates a technical requirement for pencil skills that might otherwise feel anachronistic. The child who cannot fill a bubble correctly, who bears down too hard or not hard enough, who marks outside the designated space, is disadvantaged by a gap in her education that has nothing to do with her knowledge of the subject being tested.

The broader question of whether teaching handwriting is worth the instructional time it requires in a world where most writing will be done on keyboards has genuine complexity. The answer probably varies by age, by what the handwriting is being used for, and by the extent to which fine motor skills developed through handwriting contribute to other cognitive capabilities.
