应用文写作是很多院校开设的一门公共基础课或者选修课,但教学效果却普遍欠佳。本文根据自己的教学实践及写作经验,得出如下观点:正面案例教学作为目前普遍采用的一种行之有效的方法,无疑是正确的,但仅注重这一方面是不够的。反面案例教学作为与之相对的一种案例教学法,具有正面案例教学所不可替代的作用,与正面案例教学占有同等重要的地位。 Applied Writing is a public basic course or elective course offered by many institutions, but the teaching effect is generally poor. Based on my own teaching practice and writing experience, this article draws the following viewpoints: Positive case teaching as an effective method commonly used today is undoubtedly correct, but focusing on this aspect is not enough. Opposite case teaching, as a kind of case teaching method, has the irreplaceable role of positive case teaching and occupies an equally important position as positive case teaching.
