建构主义理论倡导以学生为核心,运用多样化的教学策略激发学生的知识自主建构与深刻理解。该研究选取“对数函数的图象和性质”为例,构建了基于建构主义理论的高中数学教学设计,通过反思和总结,旨在协助学生牢固掌握核心知识点,并锻炼其数学逻辑思维与问题解决技巧。Constructivist theory advocates for a student-centered approach, employing a variety of teaching strategies to stimulate students’ autonomous construction of knowledge and profound understanding. This study selects “the graph and characteristics of logarithmic functions” as an example, constructing a high school mathematics teaching design based on constructivist theory. Through reflection and summary, the aim is to assist students in firmly grasping core knowledge points and to exercise their mathematical logical thinking and problem-solving skills.

针对灰狼优化(grey wolf optimization,GWO)算法在求解复杂高维优化问题时存在解精度低、易陷入局部最优等缺点,提出一种基于对数函数描述收敛因子的改进GWO算法。采用佳点集方法初始化种群以保证个体尽可能均匀地分布在搜索空间中;提出一种基于对数函数描述的非线性收敛因子替代线性递减收敛因子,以协调算法的勘探和开采能力;对当前最优的3个个体执行改进的精英反向学习策略产生精英反向个体,以避免算法出现早熟收敛。研究结果表明改进算法具有较好的寻优性能。
