在数学教学实践中,部分教师重知识传授轻学生探究、重学生掌握知识轻思想渗透、重教材知识轻生活资源的问题。《中考改革指导意见》明确指出“:理科在试卷上适当增加开放性试题,以培养学生的创新能力和实践能力,初步体现素质教育的要求。”数学开放性问题,指答案不确定或条件不完备、结论不确定的数学问题。数学开放题教学,能改变封闭题一统天下的现状,有利于培养学生的创新意识和创造能力,促进学生的全面发展。我们数学教师应学会编制数学开放题,笔者结合自身教学实践,谈谈开放性试题编制的几点思考。
In the practice of mathematics teaching, some teachers emphasize the importance of knowledge to explore the light students, focusing on the students to grasp the light of thinking, infiltration, teaching material knowledge of light living resources. The Guiding Opinions on the Reform of Senior High School Entrance Examination clearly states that science appropriately increases the number of open exams on test papers so as to cultivate students’ innovative ability and practical ability, and initially embodies the requirements of quality education. "The problem of open mathematics means that the answer to the question is uncertain or Incomplete conditions, the conclusion of mathematical problems of uncertainty. Teaching mathematics open questions, can change the status of the closed questions dominate the world, is conducive to cultivating students’ innovative awareness and creativity, and promote the all-round development of students. We mathematics teachers should learn to compile mathematics open questions, the author combined with their own teaching practice, talk about the preparation of open questions questions.
