摘要学生的创新思维是研究性的学习,是对现有知识的批判、继承、重置和发展,是多种思维方式互相渗透的心理活动过程。教学改革的亮点就是在全学科引导学生的创新思维。虽然没有统一的模式和办法用于执教,但是只要任课教师有胆识、多留意、多尝试,步步围绕这一教学的深度、高度和广度,总可能达到“瓜熟蒂落、水到渠成”的状态。本文以工程有限元课程的教学情况为例证,结合ANSYS计算仿真软件的教学过程,从课程教学目标的角度分析启发学生创新思维的意义,阐述强化学生创新思维的特点,提出抓好学生创新思维的策略和措施。

AbstractStudents’ innovative thinking is a research-oriented learning, a process of criticizing, inheriting, resetting and developing the existing knowledge, and a psychological activity in which various ways of thinking permeate each other. The highlight of teaching reform is to guide students’ innovative thinking in the whole discipline. Although there is no unifiedmode and method forteaching, as long as the teachers have thecourageto paymoreattention and totrymore,step by step around the depth, height and breadth of this teaching, it is always possible to achieve the state of "mature and natural".ThispapertakestheteachingsituationofEngineeringFiniteElementCourseasanexample,throughtheteaching process of ANSYS computational simulation software, from the perspective of teaching objectives,analyzes the significance of inspiring students’ innovative thinking, expounds the characteristics of strengthening students’ innovative thinking, and puts forward the strategies and measures of grasping students’ innovative thinking.

工程有限元课程是为机械设计制造及其自动化、过程装备与控制工程和材料科学与工程等专业开设的一门重要的专业拓展课。[1]它属于“三位一体”的知识结构,将数学力学基础、计算机应用和工程中的应用有机组合在一起。[2]在工程有限元课程教学中,教师在教学设计方案中纳入强化学生创新思维的元素并付诸实施,显然是明智、可行和上乘的选择。
1启发学生创新思维的意义
从总体目标看:有限元方法是指利用数学离散的方法对真实物理连续系统进行模拟,利用简单而又相互作用的单元,用有限数量的未知量去逼近无限未知量的真实系统的方法。[3]本学科教学的核心是培养学生的创新精神和实践能力,也就是使学生会用有限元知识分析和解決一般的工程问题。……
