化学实验是化学教学的灵魂,是学生认识化学的窗口和激发学生学习兴趣的主要源泉,更是培养和发展学生思维能力和创新能力的重要方法和手段。通过化学实验教学可以使学生获得生动的感性知识,从而更好地理解、巩固化学知识。为此,笔者根据自身教学实践经验,通过提取生活素材、进行演示实验及微型实验、多媒实验来增加学生实验的机会,帮助学生认识化学物质及其变化的本质和规律。 Chemistry experiment is the soul of chemistry teaching. It is the main source for students to understand chemistry and stimulate students’ interest in learning. It is also an important method and means for cultivating and developing students’ thinking ability and creative ability. Through chemical experiment teaching, students can acquire vivid emotional knowledge so as to better understand and consolidate chemical knowledge. For this reason, according to their own teaching experience, the author increases the opportunity of student experiments by extracting living materials, conducting demonstration experiments, and micro experiments and multi-media experiments to help students understand the nature and laws of chemical substances and their changes.
