Review your syllabus* (also make sure to have a copy electronically available for students to access)
Consider a mini-lesson on some of the more intriguing parts of the course and content you will cover over the semester to increase student interest and enthusiasm for content
*Don't assume students will remember everything in your syllabus going over it once on the first day. Go back, pull up the syllabus, and refer to the content throughout the class. Encourage students to consult the syllabus often.

An important element of student-centered, more engaged, learning is collaboration. When students interact and work with each other, they take a more active role in the classroom, which increases the potential to deepen and strengthen learning.
