The running stitch is still included in the ACLS-6, but the motion goes up and down in a vertical plane and the tip gets hidden underneath the backing. The truth is that the running stitch is not a very good evaluation of linear information. Colouring is better, and the back and forth motion is easy to observe. They colour on the page ignoring the line.
To Verify
Greater confidence in evaluating a pattern of performance is developed by observing different actions with different objects. Washing their hands and applying hand lotion adds practical meaning to the assessment. Polishing the silver and dusting the furniture gives the person a reason to get dressed.
To Rule Out
If the person does not colour roughly within the line. The concept of a line is not fully formed within ACL 3.2. The back and forth motion seems to drive the person toward discovering what a line is but they are not able to use the concept spontaneously. ACL 3.2 is confirmed when the back and forth motion is done in a random location. ACL 3.4 uses the concept of a line to place objects in a row or stack them up.
