现代教育技术的应用,不仅为教师提供了多样化的教学方案,而且为学生提供了多样化的外部刺激和多种认知途径。现代教育技术在化学教学中的应用以多媒体技术为主。多媒体技术与化学课程的有机结合,不仅有效地充实了化学课堂容量,降低了化学学习难度,而且提高了学生的化学学习兴趣,活跃了课堂气氛,为高效课堂的构建发挥着越来越重要的作用。一、微观现象形象化在化学教学中,学生只能观察到物质变化的宏观现象,而观察不到物质的微观变化, The application of modern educational technology not only provides teachers with diversified teaching programs, but also provides students with diversified external stimuli and multiple cognitive approaches. The application of modern educational technology in chemistry teaching is dominated by multimedia technology. The organic combination of multimedia technology and chemistry curriculum not only effectively enriches the chemistry classroom capacity, reduces the chemistry learning difficulty, but also enhances students’ interest in chemistry learning and activates the classroom atmosphere, playing an increasingly important role in the efficient classroom construction effect. First, the visualization of microscopic phenomena In chemistry teaching, students can only observe the macro phenomenon of material changes, but can not observe the microscopic changes of matter,
