Ali taught human physiology and anatomy (skeletal, circulatory, digestive, etc.), environmental sciences, renewable and non-renewable resources, fossils and overall chemistry. She found it hard to teach topics she was unfamiliar with, so she had to teach myself a lot of the time and pre-prepping for classes, because if one of her lessons went really fast then she had to teach on the fly. Her recipe for success involved pre-prepping lessons and clearly communicating with the teachers.
The most valuable things Ali taught her students/teachers were “how” to learn. In Italy, they mostly learned and taught straight from a textbook, so she introduced a ton of new technology with PowerPoint alone.
