新课程标准的一大特色是十分强调知识的应用．体现在2005年电功率部分的中考命题中,基本改变了过去以考查知识点掌握情况为目的闭门编题的陈旧出题思路,以工农业生产、日常生活的真实场景为背景的电功率题,如雨后春笋般涌现出来．这类题虽题干较长,但计算难度较小,只要耐心读上几遍,充分领会其精神实质,做起来正确率一般是很高的,下面跟同学们来领略一下其中的几种新题型．一、计算设计二合一过去中考,计算题就是纯粹的计算,设计只出现在实验题中,一般无需进行计算．计算、设计各自为政,井水不犯河水,显然这样的命题模
The major feature of the new curriculum standards is the emphasis on the application of knowledge. In the examination proposition of the electric power part of 2005, the old-fashioned problem-solving ideas for the purpose of examining knowledge points in the past have been fundamentally changed, and the electric power problems with industrial and agricultural production and real-life scenes of daily life as background have been changed. It springs up. Although such questions are longer, but they are less difficult to calculate, as long as you read them patiently and fully understand their spiritual essence, the correct rate is generally very high. Let’s take a look at some of the new ones with the students. Question type. First, the computational design of the two-in-one examination in the past, the calculation of the problem is a pure calculation, design only appears in the experiment, generally do not need to be calculated. Calculations and designs are individualized. Wells don’t commit river water. Obviously, such a propositional model
