优化课堂教学,提高教学质量,培养学生的思维能力,是当前素质教育的重要课题。在数学教学中,“练”是掌握知识和应用知识的关键。通过“练”将知识、能力,情感、态度、价值观等内化,再通过“练”将这些经过加工锤炼提升后的数学素养外化。在练习中学生可以通过动脑,动手以及动口来进一步理解和巩固所学知识,并转化为技能、技巧,从而促进学生智力,特别是思维能力的发展。只有提高了数学课堂练习的有效性,才能保证提高数学课堂教学的有效性。 Optimize classroom teaching, improve teaching quality, develop students’ thinking ability, is an important issue of current quality education. In mathematics teaching, “practice” is the key to mastering knowledge and applying knowledge. By “training” to internalize the knowledge, abilities, emotions, attitudes, values, etc., and then through the “training” to improve the mathematical qualifications after the training to externalize. During the exercise, students can further understand and consolidate what they have learned through their brains, hands-on exercises and conversations, and translate them into skills and skills to promote the development of students’ intelligence, especially their thinking ability. Only by improving the effectiveness of the practice of mathematics classroom can we improve the effectiveness of mathematics classroom teaching.
