实验教学有利于提高学生的学习兴趣和学习的积极性、主动性,有利于学生对科学概念和规律有更深刻和持久的理解,是学好化学必不可少的重要前提。因此,加强实验教学是提高化学教学质量的重要环节,也是评价教学质量的一个重要方面。在教学过程中,如何提高学生的实验技能,培养学生的创新精神和实践能力,是提高化学教学质量的首要问题。一、做好演示实验,激发学生对实验技能的兴趣教师如何在开始上课时,就能激发学生的学习兴趣呢?首先,从认识化学仪器入手,把初中化学常用仪器一一拿给学生看,当看到试管、烧杯、长颈漏斗等大小不一、形状各异的仪器时,学生们的脸上露
Experimental teaching is conducive to improving students’ interest in learning and the enthusiasm and initiative of learning, which helps students to have a more profound and lasting understanding of the concepts and laws of science and is an essential prerequisite for learning chemistry well. Therefore, to strengthen experimental teaching is to improve the quality of chemistry teaching an important part, but also to evaluate the quality of teaching is an important aspect. In the process of teaching, how to improve students ’experimental skills and cultivate students’ innovative spirit and practical ability are the primary problems to improve the quality of chemistry teaching. First, to do a good demonstration experiment, to stimulate students interest in experimental skills Teachers how to start the class, you can stimulate students interest in learning? First of all, starting from the understanding of chemical equipment, chemical instruments commonly used in junior high school one by one to students, When you see the test tube, beaker, long neck funnel and other sizes, different shapes of instruments, the students face dew
