1 试题的特点开放性问题中“开放性”是与传统问题中条件结论的“封闭性”相对而言的,其开放性主要体现在问题的答案不唯一,在知识结构方面要求学生有较全面、扎实的数学功底,在思维方式方面要求学生会自主地进行多层次、多角度的探索,其解答往往能很好地考查学生的基本数学素质,考查学生对所学知识是否具有变通的能力,是否具有知识迁移的能力,在具体情 1 Characteristics of Open Questions The “openness” of open issues is relative to the “closedness” of conditional conclusions in traditional issues. Its openness is mainly reflected in the fact that the answers to the questions are not unique, and they require knowledge structure. Students have a more comprehensive and solid mathematics foundation. In the way of thinking, students are required to independently conduct multi-level and multi-angle explorations. Their answers can often well examine the basic mathematics qualities of students and examine whether students have any knowledge of what they have learned. Ability, whether it has the ability to transfer knowledge, in the specific situation
