I have always maintained an open door policy with all of my students. They feel that I am accessible to them and they feel more secure in their surroundings. I am big with using clean concise Lesson Objectives before each section and it helps to maintain focus on the lesson being taught. I keep the Objective short and to the point so it is easy to retain. I tell them if they cannot mark off the objective to see me and get tutoring. I was able to have my students retain at least most of the information presented to them. They took something with them and didn't just pass a course.
