“测量小灯泡电功率”的实验涉及到各种电学仪器的使用,如电流表、电压表、滑动变阻器等,同时还考查了画电路图和根据电路图连接实物图的能力。在近年来中考中,以“测量小灯泡的电功率”的实验为素材命题的实验探究题,始终将实验探究能力作为重要能力进行考查。实验探究能力既包括实验操作能力,也包括实验方案设计、实验数据分析处理等方面的能力。探究能力包括严谨的科学态度、对未知事物的探究意识等方面。下面就2008年部分省市“测量小灯泡的电功率”中考实验探究题进行分类说明:
The experiment “Measuring Light Bulb Power” involved the use of various electrical instruments such as ammeters, voltmeters, and sliding rheostats. It also examined the ability to draw circuit diagrams and connect physical diagrams based on circuit diagrams. In the middle school entrance exams in recent years, experiments using “measurement of electric power of small light bulbs” as material propositions have always used experimental inquiry ability as an important ability. The ability of experimental exploration includes not only the ability of experimental operation, but also the ability of experimental design, experimental data analysis and processing. Inquiry capabilities include rigorous scientific attitudes, awareness of unknown things, and so on. The following is a classification description of the “Examination of the electric power of small bulbs” in some provinces and cities in 2008.
