核心问题是指课堂教学中“牵一发而动全身”的问题,具有直指教学目标、揭示数学本质、覆盖课堂全局、激发数学思考、推进自主学习的特点,对于促进学生主动建构、深入探究、提升思维,培养数学核心素养具有重要的意义。核心问题的提出要从数学思想的高度去追问,从利于深度探究的角度去挖掘,从培养思维素养的深度去设计,更加突出学生主体,更加突出学科本质,更加突出数学思考,从而真正达到提升学生数学核心素养,促进课堂高效的教学目的。
The core issue refers to the problem of classroom teaching, “lead one move”, has the characteristics of pointing to the teaching goal, revealing the nature of mathematics, covering the whole classroom, stimulating mathematical thinking and promoting self-learning, It is of great significance to further explore, improve thinking and cultivate the core qualities of mathematics. The core question should be queried from the perspective of mathematical thought, from the point of view of the benefit of in-depth exploration, from the perspective of cultivating the quality of thinking and accomplishment, to emphasize the subject of students more, to emphasize the nature of the subject more and to highlight the mathematical thinking so as to achieve the real promotion Student mathematics core literacy, to promote efficient classroom teaching purposes.
