人的学习是选择性学习的过程。人对外界事物的感受由于本身所具有的主客观条件的不同而不同,对事物的好恶、对错等有着自己的选择和判断。因此,学生的内在需要、期望、任务和以往的经验是决定选择性注意的重要因素。在课堂教学过程中,充分开发和利用这些因素,有利于催生课堂教学中动态生成的资源。 Human learning is a selective learning process. People’s perception of things outside the world because of their own subjective and objective conditions vary, the likes and dislikes, wrong things have their own choices and judgments. Therefore, the intrinsic needs, expectations, tasks and past experience of students are important determinants of selective attention. In the process of classroom teaching, full development and utilization of these factors is conducive to the birth of the resources dynamically generated in classroom teaching.
