Abstract 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.
