“学用结合”在这里指的是学生在课堂中学习数学基础知识和在生活实践中应用数学基础知识,并使之相互促进的一种学习形式。这种形式功效的大小,在一定程度上取决于教师对数学内容的驾驭能力和对现实生活素材的留心观察。 “Combination of learning and learning” refers here to a learning form in which students learn the basic knowledge of mathematics in the classroom and apply the basic knowledge of mathematics in their daily life and promote each other. The size of this form of efficacy depends to some extent on teachers’ mastery of math content and careful observation of material in the real world.
