现行中学自然科学教学大纲指出:培养学生的实验技能是中学自然科学教学的目的之一。大纲还要求自然科学教学在理论和实际的结合中,注意培养学生的观察、实验能力。那么,如何能更好地培养和提高学生的实验操作能力呢?接下来我就结合自己的教学实践中的体会谈一些粗浅的看法。在中学阶段,学生应该掌握的基本实验技能,“主要是学会正确使用仪器进行观察、测量和读数,会分析实验数据并得出正确的结论,了解误差的概念,会写简要的实验报告”。而实验能力,一般是指独立进行实验
The existing syllabus for the natural sciences of middle school points out that developing students’ experimental skills is one of the purposes of teaching natural sciences in middle schools. Outline also requires natural science teaching in the combination of theory and practice, pay attention to develop students’ observation, experimental ability. So, how can we better cultivate and improve students’ ability of experimental operation? Then I will talk about some superficial opinions based on the experience of my teaching practice. In the secondary stage, students should master the basic experimental skills, mainly to learn the correct use of equipment for observation, measurement and reading, analysis of experimental data and draw the correct conclusion, understand the concept of error, will write a brief experimental report ". The experimental ability, generally refers to an independent experiment
