This case study shows how students were taught the skills they need to find information relevant to their subject area. As groups of students are generally seen once only, measures to assess the effectiveness of teaching are needed, i.e. to determine the skills the students have acquired. Blogs were used as a tool for formative assessment and were used to measure student expectations before teaching, and their level of satisfaction with the session afterwards. The blog  helps the tutor to understand if learning outcomes have been achieved and whether the session has met student expectations. It also requires students to reflect on the skills that they have acquired.
