一堂堂数学课好比一次次思维的远足,在这个长途跋涉的旅途中,沿途便会不时地出现“阴错阳差”“节外生枝”“灵光一闪”的“意外风景”。这些动态生成的资源常常是在不经意间触发的“教学意外”。在中学数学课堂教学中要鼓励学生勇于质疑、做生成性资源的发现者;善待学生的错误,做生成性资源的策划者;把握教学中的意外,做生成性资源的运用者。从一节课的精致走向每节课的精彩,让数学课堂因生成而呈现出生机勃勃、精彩纷呈的动态变化。
A math class is better than time and again thinking of hiking in this long journey, there will be from time to time along the way there are “Unexpected landscape ” “exogenous” “” “unexpected scenery ”. These dynamically generated resources are often “inadvertently triggered” inadvertently. In middle school mathematics classroom teaching, students should be encouraged to be courageous to question and be the discoverer of generative resources; to treat the mistakes of students and to be the mastermind of generative resources; to grasp the surprises in teaching and to be the users of generative resources. From the exquisiteness of a class to the wonderful of each class, the mathematics class presents a dynamic and colorful dynamic due to its generation.
