Connecting Teacher Beliefs to the Use of Children’s Literature in the Teaching of Mathematics

This article presents examples that illustrate how teachers use childrens literature in the teaching of mathematics. The examples are related to four curriculum ideologies that have influenced mathematics education in the USA for the last 75 years. It discusses why it is relevant to help teachers understand the ideological positions that influence their use of childrens literature during mathematics instruction, summarizes the four ideological positions, and presents results of a study of how teachers ideological positions relate to their use of childrens literature in the teaching of mathematics. The study examines two research questionsCan an instructional tool be developed that will highlight for teachers the different ways in which they and others use childrens literature to teach mathematics? and Can that instructional tool stimulate teacher discussion and reflection about their own beliefs and the ideological nature of the instructional environment in which they learned (as students) and teach (as teachers)? Study results indicate that both questions can be answered in the affirmative.

从知识多维性看高职课程体系的维度缺失

知识的构成可从知识点、知识线、知识面、知识体和知识势几个方面来分析。教育手段在时间顺序上的一维性和教育内容在知识构成上的多维性之间的矛盾是知识传授的主要矛盾。由于高职课程体系组建尚不成熟,学科与学科之间、理论与实践之间、教学内容与行业发展之间都存在严重的维度缺失。当前的对策是:以教育大纲替代教学大纲,以知识线密度评价体系替代知识点评价体系,以改造各科教师的知识结构。
