Abstract
|
In the high school three-dimensional geometry teaching, our goal is to let the students systematically grasp the nature of spatial image, some simple polyhedron drawing skills and two volume formulas, so as to develop the students’spatial imagination ability and logical thinking ability. We are aiming at training the students to apply these knowledge further to finding, analyzing, and solving the problem. Because the power of thought and cognition is the ultimate objective of teaching.But for many years, what has mostly affected the three-dimensional geometry teaching is exactly that the students lacking in sense of space develop spatial imagination ability slowly, some even unable to form it.So the students feel terrible when someone mentions the three-dimensional geometry. We can say the student’s spatial imagination ability is very important and at the same time it determines the three-dimensional geometry teaching. This thesis is for the purpose of solving the above problems. On the foundations of consulting the massive literature and investigating the students, I attempt to train the students to draw and distinguish the figures, strengthen the position relations between points, lines and sides in common geometric figures and dig into basic concept. Combined with teaching practice, I unceasingly improve the teaching strategy and method. Finally, I come up with several inspiration and thoughts about how to improve the students’space imagination ability by comparing, analyzing and studying the experimental data.
