It is important to understand how the models you use can affect pupil understanding, practice and application, of the fluent type of movement. Look again at the words written with inconsistent rhythm. The numbers roughly indicate a count of separate movements. Look at each of the words as a series of movements. Try to decide where the movements used for each of the letters begins and ends.
Fluent movement requires knowledge of start and stop points in order to preplan the movement.
If you are having a little trouble with the decision, don't feel bad. Part of the reason is rooted in the fact that the measures show no clear indication of end points inside the word. There is considerable evidence that this fact relates directly to teaching methods and learning models which provide few clues for rhythmic interpretation or practice. The following samples could have been taken from handwriting workbooks found in many classrooms. Let's use them for a simple exercise aimed at perceiving the movements.
