This booklet is the second in a series of publications written for the United Kingdom adult and community learning (ACL) sector to assist it in improving quality. An introduction covers the rationale for observing teaching and learning in a self-assessment context. Chapter 1 concentrates on the practicalities and processes of observing teaching and learning (OTL), including how OTL information might be fed into a self-assessment report. It suggests activities for "trainee observers" that can be followed or adapted to help carry out or revise processes for OTL. Chapter 2 examines how the introduction of a system of OTL might be managed with suggestions for implementing or adapting a system of observing teaching and learning. Chapter 3 applies theory to practice through a case study. It includes a checklist for change and a way of starting calculations to cost a new system and set targets. Appendixes include 21 references and example OTL forms and guidance, session plans, and pre-observation meeting form. (YLB)
