@ Debra, the challenge was since the learners are left-handed, they find it difficult rendering the serifs to the correct direction. For instance, instead of a serif going the left direction, they rather send it to the right.
I understand your sentiments since calligraphy is penned at angle 45 degrees. Left handed students must be assisted by tilting the support (paper) to an angle of 30 degrees. For some students, they need to position the support upside down. Your left handed students need to experiment with different writing postures before knowing what may be appropriate for them.
I agree with the recommendations of Mr. Ian;however, I would like to ask two questions:
1. How many students are collected in your class?
2. Lefthanded people are not so popular. It is unlikely to find many of them in one class. Was there a discrimination criterion for collecting them together in your class? Why?
Finally, I guess that the challenge is your capability to understand their movements. I am semi-lefthanded i.e. my default hand is the left, except in eating and writing (most of the time) due to religious traditions. Sometimes, this characteristics confuse other, while I don't suffer in understanding the actions of either lefthanded or righthanded people. My advice is to not care so much about the lefthanded students in your class, but you need to improve your eyes perception for understanding them,and don't think about the left hand issue. Good luck
