教学的一个主要目标是促进习得长期的保持和迁移。就策略迁移而言,即使形式、情境发生一点小的变化都会导致迁移的产生~([1])。笔者在设计电场和磁场组合题的过程中,有意将涉及的运动形式和运动场景进行归纳比较,力求在习题中体现运动形式的递进和运动情境的变化,尽可能让习题的每个细节都成为迁移的可能条件。高中阶段常见的运动形式有匀速直线运动、匀变
One of the main goals of teaching is to promote the long-term preservation and transfer of learning. In the case of strategic migration, even small changes in the situation can lead to migration even in the form of ~ ([1]). In the process of designing the electric field and magnetic field combinatorial questions, the author intends to summarize and compare the sports forms and sports scenes involved, and strive to reflect progressive changes of sports forms and sports situations in the exercises so as to make every detail of the exercises Become a possible condition for migration. High school stage common forms of motion are uniform linear motion, uniform
