想象能力在空间认知现状以及教学策略研究.doc

摘　要 立体几何知识是高中阶段重要的内容，通过立体几何的学习提高学生的空间想象能力，同时想象能力又是学好立体几何的有力保障。想象能力是大纲中要求的七项能力之一，了运用空间向量法解决立体几何问题，所以学生的空间想象力只能在立体几何初步中，时间短，想达到更好的效果，对的空间想象力的认知现状以及采取的教学策略做深入的研究。笔者对空间想象能力进行了综述，了空间想象能力的概念、分类分层，同时对空间想象能力的研究现状做了梳理。 ，笔者所任教的两个班级进行了测试，以了解学生的空间想象能力的现状，对其中有代表性的个体进行了访谈，以精细的了解学生想法。随后进行了一次中的位置关系的测试访谈通过测试和访谈可以看出学生的空间想象能力的现状非常。对成因了分析成因寻求教学策略。 笔者学生空间想象能力的现状做出如下的教学策略：空间想象能力作用，其他研究者所研究的策略非常常规，也非常重要，笔者没有再。，此教学策略实时教学的班级与班级进行对比，教学策略学生空间想象能力有一定效果，希望这点肤浅的经验和研究结论能对大家有所裨益。数学能力 Abstract Solid geometry is an important component of high school math. Students can improve their spatial imagination ability in the process of learning solid geometry, while strong spatial imagination ability is the guarantee for students to master solid geometry. Spatial imagination ability is one of the seven skills required in outline of college entrance exam. Since the current textbook system introduces solving solid geometry problems using space vectors, students’ spatial imagination ability can only be cultivated in elementary solid geometry. Within such short period of teaching time, in order to get a better teaching outcome, deeper researches in the current situation of students’ spatial imagination skills and teaching strategies are needed. First of all, this paper presents an overview of spatial imagination ability, including the definition, diversity and stratification, as well as current research situation of spatial imagination ability. Next, based on exam scores of students in two classes, a better understanding of the current situation of students’ spatial imagination ability was gained. A more precise understanding of students’ thoughts was obtained by conducting interviews with representative students. Another exam was given in the same two classes of students and the results showed that the current situation of students’ spatial imagination ability was very far from ideal. This paper analyzes the reasons for the current situation and tries to explore a better teaching technique based on the propos
