数学教学要关注三维目标,提倡学生自己探究学习、小组合作交流学习,让学生明白生活中有数学,数学中有生活。为此,教师要以生活情景为话题,激发学生兴趣;以具体事物为基础,具化抽象概念;以任务递进为手段,训练学生思维;以课堂生成为核心,发挥学生主体作用。 Mathematics teaching should pay attention to the three-dimensional goal, encourage students to explore their own learning, team cooperation and exchange of learning, so that students understand life in mathematics, mathematics in life. To this end, teachers should take life scenarios as a topic, to stimulate student interest; based on specific things, with abstract concepts; with task progression as a means to train students thinking; to classroom production as the core, to play the main role of students.
