Who was the first woman in U.S. Air Force to teach electronics?

You question is so broadly phrased that it would be difficult to answer.  If you mean any instruction by any female  employed by the Air Force having anything to do with electronics, trying to come up with an answer would involve looking through countless training records, many of which would no longer be around because they were not necessarily have all be scheduled for permanent retention.

If you mean something very specific, such as being an instructor at a particular institution such as the Air Force Academy, you may want to contact that organization.

You can also try contacting the Air Force Historical Research Agency.
