很多学生在进行初中几何学习的时候,都反映几何学习比较困难,老师在进行几何教学的时候,也比较容易感到无所是从,因为几何本身是比较抽象的,学生在理解的时候比较困难,提高几何教学的教学效率是很多老师在教学的时候都面临的一个重要问题。而想要保证几何教学的有效性,让学生更加容易理解几何需重视例题的设计,保证例题设计的有效性,让学生更好地进行几何的学习。 Many students in the geometric study of junior high school, reflect the geometric learning more difficult, teachers in the geometric teaching, it is also easier to feel nothing, because the geometry itself is more abstract, the students are more difficult to understand, Improving the teaching efficiency of geometry teaching is an important issue many teachers face when teaching. And want to ensure the effectiveness of geometry teaching, make students more easy to understand the geometry need to pay attention to the design of examples, to ensure the validity of the example design, to enable students to better geometric learning.
