The Eduwebinar site has published a page of tools to support Inquiry Based Learning. These are organised by the steps of the Guided Inquiry process as set out in Guided Inquiry Design: A Framework for Inquiry in Your School by Carol C Kuhlthau, Leslie K Maniotes and Anne K Caspari.
For each step there are tools listed and linked to support learning – organising search strategies, organising information, presenting conclusions and supporting the evaluation of Inquiry Learning.
