数学的课堂教学,一定离不开教材中的例题.课堂上例题教学的成功与否,直接影响着课堂教学的成效.根据知识掌握的同化理论,一切新知识的掌握都是在原有知识的基础上展开的.在学习新知识时,若能准确地找到与之相对应的旧知识,及时为新知识的学习提供相对应的固定点,便能充分地理解和掌握知识的核心内容或主要部分,建立清晰的知识结构.若例题教学时注重新旧例题的联系,揭示知识领域里的内在联系,构建系统、清晰的知识结构,便能从中提高学生综合运用知识的能力.
The classroom teaching in mathematics must be inseparable from the examples in the textbook.The success or failure of the example teaching in the classroom directly affects the effectiveness of classroom teaching.According to the assimilation theory of knowledge grasping, all new knowledge is mastered based on the original knowledge In the study of new knowledge, if we can accurately find the corresponding old knowledge, new learning in time for the study to provide the corresponding fixed point, we can fully understand and grasp the core content of knowledge or the main part , To establish a clear knowledge structure.If the teaching of examples emphasizes the connection between the old and the new examples, revealing the internal relations in the field of knowledge, building a systematic and clear knowledge structure, we can improve the students’ abilities to use knowledge comprehensively.
