The middle of the semester is an excellent time to ask your students to think about, and comment on, their perspectives on the course and on your teaching. Unlike end-of-semester course evaluations, midterm evaluations offer you the opportunity not only to make adjustments in your teaching "mid-stream," but also to return to the class with thoughtful commentary on your students' feedback and suggestions. Asking students to provide feedback at mid-semester makes it clear that you take their ideas seriously and that you are dedicated to improving the course and their learning.
While you should always encourage students to talk with you if they have concerns about the course, students often need another, "low-stakes" means of communicating with you about those concerns. Moreover, providing students a chance to respond to the course, in an anonymous format, will encourage them to communicate responses that they may not feel comfortable providing in person--including positive comments.
Asking for student comments on midterm course evaluations may also help you to identify and address issues related to classroom dynamics that students might otherwise be reluctant to mention, such as issues that arise when other students are not fully participating in group work or are disrupting class by arriving late, talking to their peers, or surfing the internet on their laptops. Even when students do not address these issues themselves, midterm is an excellent time to reinforce course policies and expectations related to these issues--without "calling out" individual students.

Make a brief list of comments that you would like to respond to during the next class. Discussing your response to a few of the students' responses or suggestions will underscore to students that you do indeed take their comments seriously. For example, if students indicate that they find it hard to keep up with the pace of the lecture, you might tell them steps you are taking to adjust the pace (e.g. taking time to reinforce and review important points in the lecture, or using the chalkboard rather than PowerPoint slides to present visual information). You might also respond to student suggestions with an explanation of why you have decided NOT to make any adjustments. For example, a student in your discussion class might comment, "We should not have to raise our hands in a small class like this." You might want to mention this suggestion in class, and note that you can see some rationale for doing away with the practice of hand-raising, but then explain that you want to maintain this practice to ensure that everyone has a chance to participate (not just those students who are comfortable jumping into a discussion without raising their hands). Of course, how you respond is up to you. The important point is to make clear that you have read and devoted thought to the students' comments. Doing so will go a long way toward encouraging students to communicate with you, or your teaching assistants, about the course.
At the end of the semester, revisit the midterm evaluations, along with the end-of-semester course evaluations, to remind yourself of the feedback students provided at each stage. Then, write a few notes to yourself about specific aspects of the feedback that you will want to remember the next time that you teach.
