我们师范学校的教师常常深入小学了解一些情况。有一个现象引起教师们的普遍关注:不少在小学数学成绩不错的学生,升入初中后成绩急剧下降。这一现象的产生与学生的心理特点,思维方法,环境变化等因素有关。要改变这种状况我认为除了教师要注意初一学生的心理特点,改革教法,教师在代数起步教学中注意中、小学教材在知识上的衔接,使学生顺利地从小学过渡到中学学习外,教村能巧妙地为学生“搭桥”也是十分重要的。最近阅读了九年制义务教育教材(内地版)代数第一册(上)(以下简称(内地版)),感觉此书比以前的传统教材,更注重了这种“搭桥”的作用,下面略呈浅见。一搭由数→式的“桥”学生在小学算术中接触的是具体的,确定 Teachers in our normal school often go to elementary schools to learn about some situations. There is a phenomenon that has aroused widespread concern among teachers: Many students who have achieved good grades in primary school mathematics have experienced a sharp drop in their grades after entering junior high school. This phenomenon is related to the students’ psychological characteristics, thinking methods, environmental changes and other factors. To change this situation, I think that in addition to the teachers’ need to pay attention to the psychological characteristics of the first-year students and reform teaching methods, teachers should pay attention to the convergence of primary and secondary school textbooks in the teaching of algebraic initiation, so that students can smoothly transition from primary school to secondary school. It is also very important to teach villages how to “bridge” students skillfully. Recently I read the nine-year compulsory education textbook (Mainland Edition) Algebra 1 (above) (hereinafter referred to as (the Mainland Edition)). I feel that this book is more focused on the role of this “bridge” than the previous traditional textbooks. Slightly shallow. The use of the “bridge” students’ number-type formula in elementary mathematics is specific.
