系统论告诉我们,一个系统只有开放,不断地和外界进行物质、能量、信息的交换,才能从无序到有序,从低级走向高级。小学语文教学,应当是一个开放系统,而不能局限在课堂里,自我封闭。遗憾的是,过去由于我们过分看重考试和分数,过分强调“以（课）本为本”,只让学生在课堂里读书、? Systematic theory tells us that only when a system is open and constantly exchanges material, energy and information with the outside world can it move from disorder to order and from low to advanced. Primary language teaching, should be an open system, but not confined to the classroom, self-enclosed. Unfortunately, in the past, due to our over-emphasis on exams and scores, we placed too much emphasis on “taking this as a basis” and only allowed students to study in the classroom.
