近年来,教育改革如火如荼地开展起来,新课改要求提高课堂效率,全面推进素质教育,在保证教学质量的基础上减轻学生的学习负担,实现师生的共同发展。化学是实践性和专业性很强的学科,教师要改变传统的教学模式,将教师被动的教学转变成学生的主动学习,提高化学课堂的有效教学。 In recent years, education reforms have been carried out in full swing. The new curriculum reforms require the improvement of classroom efficiency, the promotion of quality education in an all-round way, and the reduction of students’ learning burden on the basis of guaranteeing the quality of teaching, and the common development of teachers and students. Chemistry is a discipline that is practical and professional. Teachers need to change the traditional teaching model, transform the passive teaching of teachers into active learning for students, and improve the effective teaching of chemistry classes.
