Daphne Hewson and Michael Carroll
The book Reflective Practice in Supervision provides ideas on how to create safe reflective space (reflective space is one of the six rooms of supervision), how to give and receive reflective feedback, and how to invite the practitioner to explore their actions and beliefs using mini-tools within the three stances of reflective practice: the Mindful Stance, the Consideration Stance and the Consolidation Stance.
The companion volume, The Reflective Supervision Toolkit, provides forms, tools and mini-tools for reflective supervision. Click here for a free sample
The book and toolkit are available from Amazon and many other online bookstores. In Australia, you'll find the best prices (and a spiral bound version of the toolkit) from PsychOz (psychotherapy.com.au)
