物理实验离不开实验设计,实验设计是培养学生大局观、提高学生综合分析能力、发展学生思维的重要平台。由于没有现成的实验方案,学生往往会面临许多问题和挫折,鉴于此,以“测量小灯泡的额定功率”为例,探讨如何进行实验方案的设计,并对实验方案是否具有可行性进行了具体的分析。
The experiment of physics can not be separated from the experimental design. Experimental design is an important platform to cultivate the overall situation of students, improve students ’comprehensive analysis ability and develop students’ thinking. In the absence of a ready-made experimental program, students often face many problems and setbacks. In view of this, taking “measuring the rated power of a small bulb” as an example, it discusses how to design the experimental scheme and whether the experimental scheme is feasible The specific analysis.
