化学是一门以实验为基础的自然科学,化学实验现象丰富多彩,千变万化,实验不仅为学生学习化学知识提供直观手段,实验教学还具备激发学生学习化学兴趣、培养学生解决问题能力、学习实验技能和一些科学方法、培养学生的科学品质和科学思维能力等多种教育功效。课堂上,运用恰当的实验,能使课堂的有效性获得较大提高。下面就运用化学实验提高教学有效性谈谈自己粗浅的认识。 Chemistry is an experiment-based natural science. The phenomena of chemistry experiments are colorful and ever-changing. Experiments not only provide students with intuitive knowledge of chemistry, but also stimulate students to learn chemistry, cultivate students’ ability to solve problems and learn experimental skills And some scientific methods to cultivate students’ scientific quality and scientific thinking ability and other educational effects. In the classroom, the use of appropriate experiments can make the effectiveness of the classroom to be greatly improved. Here to use chemical experiments to improve the effectiveness of teaching to talk about their superficial understanding.
