化学是一门以实验为基础的自然科学。实验以其生动、直观、新异有趣等特点,对学生具有极大的吸引力。它对巩固化学知识,获得化学实验技能、培养实事求是、严肃认真的科学态度和训练科学方法具有重要的意义,在培养学生观察能力和实验能力方面具有不可替代的作用。因此,在化学教学中我们应积极创设各种实验环境,让学生亲自动手操作实验,在实验中理解和掌握化学实验基本技能,养成求实务真的科学态度,提高他们实验的实际操作能力和分析能力,为培养创新实验操作能力打好基础。但据了解,在全国上下大力实施新课程,有效进行化学实验教学的今天,许多农村中学尤其是乡镇初中,在这方面做得还很不够。
Chemistry is a natural science based on experimentation. Experiments are very attractive to students because of their vivid, intuitive, new and interesting features. It plays an important role in consolidating chemical knowledge, acquiring chemical experiment skills, cultivating practical and realistic attitudes, serious scientific attitudes, and training scientific methods. It plays an irreplaceable role in cultivating students’ observation and experimental abilities. Therefore, in the teaching of chemistry, we should actively create a variety of experimental environments, allow students to personally operate experiments, understand and master the basic skills of chemical experiments in experiments, and develop a true scientific attitude to practical work, and improve the actual operational ability of their experiments. Analytical ability lays the foundation for cultivating innovative experimental operational capabilities. However, it is understood that the implementation of new curricula throughout the country and effective chemical experiment teaching today, many rural middle schools, especially junior middle schools in towns and villages, do not do enough in this regard.
