化学是以实验为基础的自然科学,在中学化学教学中,必须重视实验教学。化学教师要在每一节新课中设计、创新一些实验,可以吸引学生的学习兴趣、培养学生的观察能力、动手能力,在提高学生的核心素养方面有着不可代替的作用。中学化学教师必须知道化学实验在课堂教学中的意义及价值,以及现行教材中实验的作用,更要创新一些小实验,提高实验在新时期教育改革中化学教育的价值。
Chemistry is an experiment-based natural science. In middle school chemistry teaching, we must attach importance to experimental teaching. Chemistry teachers should design and innovate some experiments in each new lesson, which can attract students’ interest in learning, develop students’ observation ability and practical ability, and play an irreplaceable role in improving students’ core literacy. Chemistry teachers in secondary schools must know the significance and value of chemistry experiments in classroom teaching as well as the role of experiments in current textbooks. They also need to innovate some small experiments and enhance the value of chemistry education in experiments in the new era.
