数学开放性问题在开放的时代应运而生。近年来,数学开放性问题已成为数学教育中解决问题的重要工具,这类问题的引进使数学教育更加接近现实数学,使学生充分体验到数学问题与现实问题的密切相关性。开放型问题中的“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 The open question of mathematics came into being in the open era. In recent years, the problem of open mathematics has become an important tool for solving problems in mathematics education. The introduction of such problems brings mathematics education closer to real mathematics and enables students to fully experience the close correlation between mathematical problems and real problems. The “openness” of open-ended questions is relative to the “closedness” of the conditional conclusions in traditional problems. Its openness is mainly reflected in the fact that the answer to the question is not unique.
