This research randomly choose a key high school , a common high school and a urban high school in guilin , and the purpose is to explore the influence of school in function concept learning and the processing mechanism of function concept schema 本实证研究随机选取桂林市重点中学、普通中学以及农村中学各一所,探究图式在函数概念学习中的影响以及函数概念图式的加工机制。主要结论: ( l )图式是一种高级的学习策略。
After teaching the chapter of function , we once did a questionaire to the first grade senior student in high school , the analysis result show that the student have n ' t had deep understand to the concept of function , in their mind , there exists prior knowledge , which keep them away from the practical - questions with function concept well , there is still some distance between their realization of concept and convey of the conceptual symbols 在学习函数这一章节后,我们曾对高一年级学生进行了一次问卷调查,调查结果发现,学生对函数概念理解不够深刻,明显存在“先验知识” ,不能很好地运用函数概念解决实际问题,在对概念的认识与概念符号表达上存在一定的距离。
The dynamic model of grey is comeing or bring into being the function concept with the grey serving as the foundation , and with the differential drawing up closing the pattern the building method for the nucleus , to build pattern thought is directly changing the time alignment to the differential equation grey system , thus builds that the development abstracting the system changes the dynamic model , and namely grey ' s dynamic ' s model , ' s brief note is for gm 灰色系统理论与方法的核心是灰色动态模型,其特点是生成函数和灰色微分方程。灰色动态模型是以灰色生成函数概念为基础,以微分拟合为核心的建模方法,灰色系统建模思想是直接将时间序列转化为微分方程,从而建立抽象系统的发展变化动态模型,即greydynamicmodel ,简记为gm 。
