摘　　要：针对当前高三化学实验常态复习难以适应"素养为本"的实验试题考查要求的现状,提出了以深度学习指引高三化学实验有效复习的设计思路:精选学习主题、设计学习任务、进行实时评价,并以"七水合硫酸锌的制备、葡萄糖酸锌的制备、葡萄糖酸锌的纯度测定、构建认知模型"为主线,设计了"葡萄糖酸锌的制备及纯度测定"一课,为高三化学实验的深度复习提供了可资借鉴的设计思路和教学案例。In order to improve the current situation that the normal review of chemistry experiments in Senior 3 is difficult to meet the literacy-based requirements about additional test questions of chemistry experiments, this paper proposes a deep learning idea to guide the effective review of chemistry in senior 3,which contains selecting learning themes, designing learning tasks and conducting real-time evaluations. Taking preparation of zinc sulfate heptahydrate, preparation of zinc gluconate, purity determination of zinc gluconate, and construction of cognitive model as the main line, this paper designs a lesson on the preparation and purity determination of zinc gluconate, which provides a design idea and a teaching case for the in-depth review of the chemistry experiments in senior 3.
