《数学课程标准(实验稿)》在教学建议中指出:“要创设与学生生活环境、知识背景相关的、学生感兴趣的学习环境,让学生在观察、操作、猜测、交流、反思等活动中逐渐体会数学知识的产生、形成与发展。”从这段话中,我们可以明确关于创设教学情境的三 “Mathematics Curriculum Standards (Experimental Draft)” pointed out in teaching suggestions: “We must create learning environments that are relevant to the students’ living environment and knowledge background and are of interest to students so that they can observe, manipulate, guess, communicate, reflect, and other activities.” Gradually learned the emergence, formation and development of mathematics knowledge." From this passage, we can clearly identify three ways to create teaching situations.
