纵观2004年中考,出现了不少探索开放型试题,这类试题指缺少一定的题设和结论,需要通过分析、推理、补充一定的条件和结论,使之成为一个完整的数学问题.由于这类考题形式新颖、思考方向不确定,因此综合性和逻辑性较强,它着力考查学生观察、分析、比较、归纳、推理等方面能力,对提高学生的思维品质,培养学生独立发现问题和解决问题的能力大有益处.
Looking at the 2004 mid-term exam, there have been many open-ended exam questions. These exam questions refer to the lack of certain questions and conclusions, and need to be analyzed, reasoned, and supplemented with certain conditions and conclusions to make it a complete mathematical problem. This type of exam questions is novel in form and its direction of thinking is uncertain. Therefore, it is comprehensive and logical. It focuses on the ability of students to observe, analyze, compare, generalize, reason, and other aspects, to improve students’ thinking quality, and to cultivate students’ independent discovery problems. The ability to solve problems is of great benefit.
