| Spatial imagination ability is one of the three "thinking abilities" in mathematics.Improving the spatial imagination ability of high school students is one of the requirements of high school curriculum standards for students’ thinking ability,which can promote the improvement of students’ mathematical literacy.Studing the cultivation of spatial imagination ability is the need to improve the quality of mathematics teaching in senior high school and to cultivate students’ mathematical thinking ability and application ability.Through literature research,we can understand the existing achievements of spatial imagination research at home and abroad.On the basis of defining relevant concepts,we establish the theoretical basis of the research as the theory of spatial imagination hierarchy.Through questionnaires and analysis,we can understand the current situation and differences of high school students’ spatial imagination ability.Then we can make textbook analysis and the analysis of college entrance examination questions;Based on the practical research,we put forward specific measures to improve the spatial imagination ability of high school students.The research holds that the following teaching strategies should be adopted in high school mathematics teaching: in terms of concepts,both teachers and students should attach importance to the role of spatial imagination ability,and teachers should examine the cultivation value of spatial imagination ability from the perspective of students;in terms of classroom teaching,teachers should guide the students to understand the chart,the drawing,and enhance their interest in learning;in terms of knowledge study,teachers should do well in the mutual transformation and transfer of plane geometry and solid geometry.At the same time,teachers also need to develop different teaching methods according to the collective or individual differences,which can help students to train their spatial imagination ability. |
