为探索小学高年级阅读和写作的教学方法和策略,根据建构主义中“任务驱动”理论,我们提出了“写读结合,单元整合”的教学理念,通过写的任务驱动,最大限度地激发学生的学习动机,让学生积极主动地建构知识,在教学中实现效率最大化。“写读结合,单元整合”教学以学生的元认知为基础,根据单元训练重点和单元习作,在充分了解学情的基础上引入待解决的问题或学习任务,以引发认知冲突,并通过单元整合和各种课型,分解问题和任务,让学生在解决和完成一个个的小问题或任务中自主建构知识, In order to explore the teaching methods and strategies of high school grade reading and writing in primary school, according to the “mission-driven” theory in constructivism, we put forward the teaching concept of “combination of writing and reading, unit integration” Limit the motivation of students to stimulate students to take the initiative to build knowledge, to achieve maximum efficiency in teaching. “Writing and Reading Integration, Unit Integration ” teaching is based on the students’ metacognition. Based on unit training focus and unit practice, students are required to introduce the problems or learning tasks to be solved on the basis of fully understanding the learning conditions so as to trigger cognitive conflicts , And through unit integration and a variety of coursework, decomposition of problems and tasks, so that students solve and complete a small problem or task to build their own knowledge,
