情境创设理论的倡导者布鲁纳认为,能否使学习取得最佳的效果取决于学习者是否能够创设一定的问题情境,对学习材料进行亲身体验。如果学习者能够做到这一点,把自己的学习与“情境”很好地结合,就能够学得最有价值的东西。问题情境的设置则是数学教学中的常用手段和方法。笔者在多年的教学实践中总结出,数学教学中“问题情境”的设置要注意如下两大方面:一、是否在课堂教学的始终贯穿情境创设意识在数学课堂教学中应该始终贯彻情境教学,不管是课堂教学开始和过渡阶段,还是课堂教学的主体或后期。教师应努力在全 Bruner, an advocator of context creation theory, believes that the best effect of learning depends on whether learners can create certain problem situations and experience the learning materials firsthand. If learners can do this and combine their learning well with “context”, they can learn the most valuable things. The setting of problem situation is a common method and method in mathematics teaching. The author summarizes many years of teaching practice, mathematics teaching “problem situation ” setting should pay attention to the following two aspects: First, whether in the classroom teaching has always been through the context of creating awareness in the mathematics classroom teaching should always implement situational teaching , Whether it is the beginning of the classroom teaching and the transitional stage, or the main body of the classroom teaching or later. Teachers should work hard in the whole
