“模型思想”是《义务教育数学课程标准(2011版)》十大核心词之一,也是当下引领有效教学、拓展学生思维的核心指导思想。然而,“模型思想”如何培养?成为困扰一线教师的一大难题。教学实践证明,第二学段从“创设情境,为建模作准备”、“充实题材,丰富建模途径”、“多维尝试,感悟模型求解”和“回归生活,体悟模型优势”这四个方面建构“模型思想”的教学策略,对发展学生的学习兴趣、提升学生的数学素养、内化学生的数学思维至关重要。
“Model Thought ” is one of the ten core words in the Compulsory Education Mathematics Curriculum Standard (2011 Edition), and it is also the core guiding ideology that leads effective teaching and expand students’ thinking. However, how to cultivate the “model thinking” has become a major challenge to front-line teachers. The teaching practice proves that the second semester returns from “creating situations and preparing for modeling”, “enriching the theme and enriching the modeling approach”, “multidimensional attempts, sentiment model solving” and “return to life, Comprehend the advantages of the model ”The four aspects of building “ model thinking ”teaching strategy, the development of students’ interest in learning to enhance students’ mathematical accomplishment, internalization of students’ mathematical thinking is essential.
