发现问题是思维的逻辑起点,问题意识是学生主动探索的动力和源泉。教学中适时的提问,能激发学生的学习兴趣,促使学生思考和探索。中学数学教学中,预设情境,有意识地引领学生质疑、思考和探索,培养学生的问题意识,对理解和把握教学内容,培养创新精神具有重要作用。在教学实践中,有关学生问题意识的培养,笔者主要从以下几方面入手。1从数学教材中发现问题有关观察、思考、讨论、操作、练习、探索的练习和要求在中学数学课程中多有体现,教授这些内容时,笔者积极引领学生开动脑筋,动手动脑,发现问题,进而寻找解决问题的途径和方法。例如,“等腰三角形
Found that the problem is the logical starting point of thinking, problem awareness is the driving force and source of student exploration. Timely questions in teaching can stimulate students' interest in learning and encourage students to think and explore. Middle school mathematics teaching, the default situation, consciously lead the students to question, think and explore, cultivate students' awareness of the problem, to understand and grasp the teaching content, to cultivate innovative spirit plays an important role. In teaching practice, regarding the cultivation of student's problem consciousness, the author mainly starts from the following aspects. 1 problems found in mathematics textbooks The practice and requirements of observation, thinking, discussion, operation, practice and exploration are often reflected in the mathematics curriculum of middle school. When teaching these contents, I actively lead students to use their brains, Then find ways and means to solve the problem. For example, ”isosceles triangle
