The first third of Harvard's Math 23a includes finite fields in Linear Algebra. It is available as an online class. https://www.extension.harvard.edu/academics/courses/linear-algebra-real-analysis-i/15176 https://www.extension.harvard.edu/academics/courses/linear-a... For example, see https://youtu.be/c194lY79jOM https://youtu.be/c194lY79jOM minute 16:30 The course makes no specifics for finite fields but does illustrate that linear algebra works for any field, finite or not.
