This chapter provides an overview of usability and reflects on a number of years of experience in a usability lab. Over this time, an approach to usability testing called situated co-inquiry was developed. Situated co-inquiry also became a very useful way to structure the teaching of usability. This chapter illustrates this teaching and some of the ways an experiential learning approach has been used in a group setting. I hope that some of this will be new and appealing to you and so assist you to generate fresh ideas in your teaching of the different areas of information systems (IS).
