数学教师是数学课堂的主导者,是学生数学学习的引导者、帮助者,如果教师缺少正确的数学认识,缺少恰当的教学加工能力和指导能力,就很难保证课堂教学与数学的恰当对应,因此数学教师是保证“教与数学对应”的最主要因素。根据数学教育的双逻辑模型,数学教师可以从以下四个方面提高课堂教学的学科性。 As a leader of maths class, maths teachers are the leaders and helping helpers of maths learning. If teachers lack correct understanding of maths and lack proper teaching ability and instruction ability, it is difficult to ensure proper correspondence between class teaching and maths, Therefore, math teacher is the most important factor to ensure that “teaching and mathematics correspondence”. According to the double logic model of mathematics education, mathematics teachers can improve the discipline of classroom teaching from the following four aspects.
