TK/PPD: Theory of Knowledge Presentation Planning Document: Download this PDF, save it in a safe place, and, as you make decisions about your presentation, record important information in the TK/PPD. This document is AS IMPORTANT as the Presentation, in that it is an audit trail of your thinking and a report of the knowledge questions, real-life situation, knowledge claims, counterclaims, perspectives, and implications in your discussion. If these things are not outlined in the TK/PPD, it is not the teacher's responsiblity to offer the IB scorers a book report of your presentation, and you may be moderated down.
