学生学习新的数学知识,都是在原有学习的基础上进行的。数学知识前衔后接的严密系统性,使学生原有认知结构中的先知,“时刻准备着”去同化和接纳新知。充分利用学生先前认知结构中的相关知识对后继学习施以积极影响,常常能为新知学习提供同化点,使“新知的航帆停泊在已知的锚桩上”。所以,要想使学生真正理解和掌握新知,就得用鲜明的准备意识去认真再现和努力唤起学生认知结构中的相关旧知,让它们在学生脑中“活跃”起来,使学生
Students learn new mathematical knowledge, are based on the original study carried out. The tight system of mathematics before the title, so that the original cognitive structure of the students in the students, “always prepared” to assimilate and accept the new knowledge. Making good use of the relevant knowledge of previous cognitive structures of students to exert a positive influence on subsequent learning can often provide assimilation points for new learning so that the new informed sail is anchored to the known anchor pile. Therefore, in order for students to truly understand and grasp the new knowledge, they must use the clear preparation consciousness to seriously reproduce and strive to arouse the students' cognitive structure in the relevant old knowledge, let them “active” in the student brain so that students
