Some truth here, but some of what she describes (e.g. no example problems with worked solutions to learn from) are not sensible if you want people to learn. Imagine if programmers had only the definition of what a function does, but example code using it was banned from all documentation (and no Stack Overflow). Especially in a math class intended for non-majors, it's an odd policy.
