课堂教学是预设性与生成性相统一的师生互动活动。预设性与生成性是课堂教学活动的双重本质,把二者割裂开来并使之对立,是一种形而上学“独断论”的思维。采用问题教学法,教师将体现教学目标要求的问题贯穿于教学过程,学生在设问和释疑的过程中自主生成知识和能力,这种课堂教学模式才能实现预设性与生成性的融合一致,体现教师主导作用与学生主体地位的和谐统一。 Classroom teaching is the interaction between teachers and students, which is a combination of prescriptiveness and generativeness. Pre-setting and generativeness are the dual essences of classroom teaching activities. It is a kind of metaphysics “doctrine ” thinking that the two are separated and opposed.
