A varied approach is one that tries different methods in order to get to what is best for the students. Lecture, demonstration, discussion and so forth are all good. But, be flexible.

Making a good first impression is important. But, it is also important to continue this good start in subsequent classes. Students will benefit from such an approach.

Even if the learning environment is not ideal, instructors need to be positive and persevere.

Some students have special problems in learning. Instructors need to be sensitive about such situations.
