从一般理论到具体实践的还原,和从具体实践到一般理论的升华一样,都是复杂和艰难的。对教师来说,更加重要的是实现还原。如何做才能实现从一般理论到具体实践的还原?实现这一还原,不仅涉及到步骤和模式问题还涉及到类型等问题,不仅要透彻把握和运用一般步骤和模式,还要准确把握 The reduction from general theory to concrete practice is as complex and difficult as the sublimation from the concrete practice to the general theory. For teachers, it is more important to achieve reduction. How can we achieve the reduction from the general theory to the specific practice? To achieve this reduction, not only involves the problems of steps and models but also involves types and other issues, not only to thoroughly grasp and use the general steps and modes, but also to accurately grasp
