1) The document discusses the teaching games for understanding (TGfU) model and how it can be applied to coaching field hockey. TGfU focuses on developing players' understanding of games through representative practice experiences rather than isolated skill drills.
2) It outlines four pedagogical principles of TGfU - sampling, tactical complexity, modification and exaggeration. These principles guide how coaches can design developmentally-appropriate small-sided and modified games to teach tactical concepts.
3) The document provides examples of how coaches can progressively increase tactical complexity across levels to develop principles of play like penetration, support and width in attack, as well as delay, depth and balance in defense.
