新课标下焦点弦的教与学

Teaching and Studying Focus Chord under New Course Standard

新的数学课程标准是在以学生发展为本的理念下,要求学生转变学习方式,教师积极探索要求师生转变教与学的观念,加深对课本内容的拓展理解和应用.所以,在数学教学中,教师要善于引领学生对课本的一些重要几何量进行探索与研究,以提高学生的数学素质和应试能力.

Based on the students＇ development, the new course standard requires both teachers and students transform their attitudes towards teaching and studying, that is, students are demanded to convert studying methods and teachers to explore actively new class teaching methods so as to deepen the understanding and application of what is studied. Therefore, teachers are suggested to guide students to explore and research important geometry concepts in the textbook with an aim to enrich their mathematic knowledge and enhance their examination performance.
