教材建设历来是提高教学质单的根本，是师生在教和学过程中教学内容的依据。因此在成人教育各科专业培训或学历教学方面的用书都由全国性专业教材编审委员会领导组织编写，并专人主审送出版社出版。不论是试用或正式教材理应保证不能有概念性错误，这是最起码的前提。令人遗憾? Teaching materials has always been to improve the quality of teaching a single basic, teachers and students in the process of teaching and learning teaching content. Therefore, adult education subjects in various professional training or academic teaching books are written by the national professional teaching materials review committee leadership organization, and written by the trial press to Publishing House. Whether it is trial or formal teaching should ensure that there can be no conceptual error, this is the minimum prerequisite. Regrettable?
