教科书提供教学素材瑕疵及矫正探析——透过学生阅读与教师施教的视点

An analysis of the flaw and rectify of teaching materials provided by textbooks: through the perspective of students’ reading and teachers’ teaching

编制数学教科书时,由于受到几个主要方面的限制,如进入公库的数学知识依据逻辑表述;体现时代数学教育教学理念,如强调生活化的数学情境等;教科书编制中的文字量的限制;编制专家亲身数学教学设计及其课堂实施的实践经验等.导致载入数学教科书中的少数教学素材不方便于教师施教,也不利于学生通过比较独立的阅读方式学习.数学教师必须处理好这些问题,才能提高数学教学的有效性.

When compiling mathematics textbooks, it is chiefly restrained by several major aspects, such as the logic expression of criteria for mathematical knowledge entering the public corpus;the reflection of the teaching concept of mathematics education of the times, such as the emphasis of the real life mathematical situation, etc.;the amount of words restraint in the compilation of textbooks;the in-person mathematical teaching design of textbook compiling experts and their practical experience in classroom implementation etc. As a result, some teaching materials adopted in mathematics textbooks are blamed for its inconvenience for teachers to teach, and brings inconvenience for students to learn by means of relatively independent reading methods. Maths teachers must handle these problems with care in order to improve the effectiveness of mathematics teaching.
