Development of the flipped class.

In fall 2018, the course was structured as a lecture class. In fall 2019, the course was divided into two sections: a lecture class with review and a flipped class. Both class sections included the same review questions provided as: 1) open-ended review questions in the reading notes, 2) true-false questions in pre-quizzes, and 3) multiple-choice questions in post-quizzes. In fall 2020, the class was structured as a flipped class with additional review questions and new lecture recordings.
