一、基本要求知识面同现行教材相比,基本不变,主要在深度方面降低要求:1.降低概念的抽象严谨程度。如力学中即时速度的概念不用极限来讲;能的概念从“能够做功的物体具有能”引入等等。2.降低规律的理论解释和推理论证水平。有些公式、定律(如向心力、向心加速公式、单摆周期公式等)在演示实验的基础上直接给出,不进行推导;有些降低了理论解释,如光的干涉只作定性的讨论等等。3.降低计算要求,如力学部分不要求用矢量式进行计算,不要求解连接体问题;电学部分,二年制高中不要求计算电势能、洛仑兹力、带电粒子在匀强电场中的加速、减速、偏转问题。有些只要
First, the basic requirements of knowledge compared with the existing textbooks, basically unchanged, mainly in depth to reduce the requirements: 1. To reduce the concept of abstract rigor. For example, the concept of real-time speed in mechanics is not limited; the concept of energy can be introduced from objects that can do work. 2. Reduce the theoretical interpretation of the law and infer theoretical level. Some formulas and laws (such as centripetal force, centripetal acceleration formula, single pendulum cycle formula, etc.) are directly given on the basis of demonstration experiments without derivation; some reduce theoretical explanations such as light interference only for qualitative discussions, etc. . 3. Reduce the calculation requirements, such as the mechanical part does not require the use of vectorial calculations, do not solve the connector problem; the electrical part, two-year high school does not require the calculation of potential energy, Lorentz force, charged particles in the uniform electric field acceleration , deceleration, deflection problems. Some as long as
