These patterns are bottom up rather than top down.
The pattern of our language is top down.
The early childhood tendency to start close and move away frequently leads to one of these approaches when a little one invents his or her own way to create the letter. Lefties tend to move counter clockwise, righties clockwise. Either way, the bottom-to-top process is a reversal of our top-down language pattern.
There is another consideration. These patterns will not correlate with cursive production. Virtually all first grade pupils are experimenting with cursive before the end of the school year. A correct print pattern makes the cursive process easier to understand and learn. Thousands of digital samples reveal these reversals to be common. Do these poor patterns contribute to the fact that so many intermediate pupils are not able to take advantage of cursive for fluent word processing?
Our digitizer has measured the difference between fluent, automatic movement and the alternative. If you must work carefully to produce legible results, you are quickly frustrated with writing. The frustration leads too many to avoid the use of writing as a tool for learning and communication. The need for automation and fluency leads a majority of our students in intermediate grades to revert to printwriting.
Our digitizer has allowed measurement of movement in thousands of samples. We now know the reason for all of the requests to print. Please read "John and Jane are bright. Why can't they write?" You will find a link to the paper on our welcome page. It will help you to give the gift of fluency to your students.
