一、课本为什么要改编全日制十年制学校高中化学课本第一册(试用本)自1979年出版以来,已经使用了将近四个学年了。这四年来,全国教育情况有了发展变化,教师对使用教材也积累了不少经验并提出了许多改进建议。因此,有必要结合我国教育实际情况,吸取教师们的经验和建议对课本进行改编。 I. Why textbooks need to be rewritten in full-time, 10-year schools. The first volume of chemistry textbooks for senior high school (trial version) has been in use for nearly four academic years since its publication in 1979. In the past four years, the national education situation has undergone development and changes. Teachers have also accumulated a lot of experience in using teaching materials and made many suggestions for improvement. Therefore, it is necessary to combine the actual situation of education in China and draw on teachers’ experience and suggestions to adapt textbooks.
