一、完成“系统工程”之时在小学数学学习过程中,遇到相对简单的学习内容,学生可以通过自学掌握大部分知识点,但教学难点则需要通过小组交流的方式进行学习。这类知识点在设计教案时,教师往往会通过出示学习提纲,先由学生自主学习,然后小组讨论、交流反馈后,由教师引导梳理的方式来解决,我把这样的设计称之为“系统工程”。例如在教学三年级下册“年、月、目”一课时,在创设情境引出课题之后,教师就可以为学生提供不同年份的日历,相机出示学习提纲:
First, the completion of “system engineering ” At the primary school mathematics learning process, encountered a relatively simple learning content, students can learn most of the knowledge points by self-learning, but the teaching difficulties need to learn through the group exchange. Such knowledge points in the design of lesson plans, teachers often through the production of syllabus, first by the students to learn, and then group discussions, exchange feedback, instructed by teachers to sort out ways to solve, I call this design System Engineering ". For example, in teaching the third grade under the book year, month, head of a class, the creation of the situation leads to the subject, the teacher can provide students with different years of the calendar, the camera shows a syllabus:
