新课改下的数学教材改变了传统教材中单一、机械的例题呈现形式,把侧重点放在从学生熟悉的童话世界、学校生活、家庭生活当中,以主题图的方式呈现在学生面前。主题图的有效应用对于提高课堂教学质量起着不可替代的作用,在小学数学的教学过程中,其重要地位不可言喻。 Under the new curriculum reform, the mathematics textbooks have changed the single and mechanical examples presented in the traditional textbooks. The emphasis is put on students’ fairy tales, school life and family life. The effective application of thematic maps plays an irreplaceable role in improving the quality of classroom teaching. In the teaching process of elementary mathematics, its important position is ineffable.
