Do American children still learn handwriting in school? In the age of the keyboard, some people seem to think handwriting lessons are on the way out. 90% of teachers say they are required to teach handwriting.But studies have yet to answer the question of how well they are teaching it. One study published this year found that about three out of every four teachers say they are not prepared to teach handwriting. Some teachers are teaching handwriting by providing instruction for 10 15 minutes a day, and then other teachers who basically teach it for 60 to 70 minutes a day — which really for handwriting is pretty much.

Many adults remember learning that way — by copying letters over and over again. Today’ s thinking is that short periods of practice are better. Many experts also think handwriting should not be taught by itself.Instead, they say it should be used as a way to get students to express ideas. After all, that is why we write.

Handwriting involves two skills. One is legibility,_which means forming the letters so they can be read. The other is fluency — writing without having to think about it. Fluency continues to develop up until high school.

But not everyone masters these skills. Teachers commonly report that about onefourth of their kids have poor handwriting. Some people might think handwriting is not important any more because of computers and voice recognition programs.

But Steve Graham at Vanderbilt says word processing is rarely done in elementary school, especially in the early years. American children traditionally first learn to print, and then to write in cursive, which connects the letters. But guess what we learned from a spokeswoman for the College Board, which administers the SAT college admission test. More than 75 percent of students choose to print their essay on the test rather than write in cursive.
