数学开放性试题是相对于传统的条件完备、结论明确的封闭题型而言的,是指那些条件开放(条件不完备,存在多样化)、结论开放(无固定结论或结论较多的)、解题策略开放(可以采用多种思想方法和途径去解决)的问题,因能很好地考查学生的创新意识与创造能力而备受命题者的青睐.下面归类举例说明.一、结论开放结论开放性试题,是让解题者根据给出的问题条件,去探索相应结论的一类试题,一般来说,符合条件的结论往往存在较多.
The open question of mathematics is relative to the traditional closed-ended questions with complete conditions and definite conclusion. They are those with open conditions (incomplete conditions and diversified existence), open conclusions (no definite conclusions or conclusions) Problem-solving strategy open (you can use a variety of ways and means to solve the problem), because they can well examine the students' innovative awareness and creativity and much proponents of the favor. The following classification examples. First, the conclusion of open Conclusion Open questions, is to enable problem solvers according to the given conditions of the problem, to explore the corresponding conclusions of a class of questions, in general, meet the conditions of the conclusions tend to exist more.
