Within ACL 5.2, the person is able to complete three single cordovan stitches after two demonstrations. The retention of the new, third dimension information is slow.
We initially thought the copying activity did not have a good differential between ACL 5.0 and 5.2 until we realised we had introduced surface appearance in the colour of the tiles. The original recessed tile box had hand sanding and staining the wood as the distinguishing factor between the two modes, but boxes are not practical. Use the sketching or peanut butter activity instead to differentiate between the modes.
