多媒体技术作为一种有效的辅助教学手段,已在不少学科的教学中产生了积极的作用。信息技术与化学课堂的整合,为学生的自主学习提供了一个良好的学习环境,降低了学习难度,开阔了学生的知识视野,丰富了课余知识,提供了生生、师生合作交流的天地。因而怎样提高化学课堂的有效性,是一个值得研究的课题。 As an effective auxiliary teaching method, multimedia technology has played an active role in teaching many subjects. The integration of information technology and chemistry classrooms provides a good learning environment for students 'autonomous learning, reduces the difficulty of learning, broadens students' field of vision, enriches after-class knowledge and provides a world where students and students can exchange and exchange ideas with teachers and students. Therefore, how to improve the effectiveness of chemistry class is a subject worth studying.
