一、提出问题近年来,各地的高考数学试题呈现出“规避特殊技巧,凸显数学本质,强调过程性评价,引导研究性学习”等特色,对中学数学教学起到良好的导向作用,推动着数学改革的深化.同时作为选拨性考试,试题必须兼顾基础性和发展性,具备应有的信度、效度、难度和区分度.各类压轴题自然担当起改革和创新试验田重任,试题的解决情况是学生分数高低的分水岭,关乎学生的“命运”.一般说来,客观题“压轴题”具有内隐性、创新性、综合性等特点,难度往往超过解答题第
First, the question raised In recent years, the math test questions around the college presents a “special skills to avoid, highlighting the nature of mathematics, emphasizing the process of evaluation, to guide research learning” and other characteristics of mathematics teaching in secondary schools play a good role in guiding and promoting At the same time as a selective examination, the test questions must take into account the basic and development, with due reliability, validity, difficulty and distinction.All finale questions naturally assume the task of reform and innovation test field, Generally speaking, objective questions “finale questions ” have the characteristics of implicitness, innovation and comprehensiveness, and the difficulty is often more than the solution to the problem No.
