情境创设是为了有效教学活动的开展,而不只是为了课堂气氛的活跃,其首要任务是服务于数学的学习,应该让学生用数学的眼光关注情境,应该为数学知识和技能的学习提供支撑,为数学思维的发展提供土壤。如果教学情境妨碍了有效的教学,那么这样的教学情境就缺乏有效性。因此,要创设有效的教学情境,应注意到以下几个方面。 Situation creation is to carry out effective teaching activities, not just for the classroom atmosphere of activity, its primary task is to serve the mathematics learning, students should allow students to focus on the situation with a mathematical perspective, mathematics knowledge and skills should provide support, Provide the soil for the development of mathematical thinking. If teaching situations prevent effective teaching, then such teaching situations are not effective. Therefore, to create an effective teaching situation, we should note the following aspects.
