There is a moment in every act of teaching when something shifts—a threshold is crossed, a clearing emerges, a question unsettles, an insight lingers. These moments are rarely scripted. They defy method or reduction. Yet in their unfolding, they reveal something essential about the nature of thinking as it is lived, shared, and called into being. This chapter traces those moments, gathering the textures, tensions, and tacit structures that constitute the phenomenon of facilitating Higher-Order Thinking Skills (HOTS).
