TopHat, a Canada-based education-service company, has published the booklet “The Top Tactics for Creating a More Engaged Classroom” together with InsideHigherEd. It has gathered good practice from universities like Stanford, Purdue and Wellesley College with the respective university professors describing how to start their classroom interaction [e.g. by inviting the students to critique their syllabus], how they keep up the level of engagement [e.g. by running classes more like meetings], and how they improve the evaluative aspects of their class.
