练习是数学课堂教学活动的重要组成部分,是促进学生全面、持续、和谐发展的重要途径。教学实践证明:激发学生学习的兴趣是使学生真正成为课堂的主人,提高教学效率的重要途径。如果我们在平时的教学中能注重提高练习的有效性,让练习落在实处,而不是一味的高题海战,而是激活学习兴趣,彰显课堂实效。 Exercises are an important part of mathematics classroom teaching activities and an important way to promote students’ comprehensive, sustained and harmonious development. Teaching Practice proves: to stimulate students interest in learning is to make students truly become the masters of the classroom, an important way to improve teaching efficiency. If we can pay more attention to improving the effectiveness of exercises during normal teaching, we should make the practice a reality rather than a blind high-level naval battle. Instead, we should activate the interest in learning and demonstrate the effectiveness of the classroom.
