This book contains three modules, each arranged into six units of work. The units of work may also be used separately, as stand-alone teaching activities. The modules are: 'what is truth?'; the theory of knowledge; and, arguing effectively. The book includes: introduction, clear teacher's notes on suggested teaching activities, background information for teachers on religious and philosophical ideas encountered, assessment examples, differentiated activities, photocopiable worksheets, and a CD-ROM containing all the worksheets. Although developed for Key Stage 3, the differentiated activities mean that this resource can also be used through GCSE, and as an introduction to AS work in religious studies, philosophy and ethics and critical thinking.
