数学教学特别强调练习的重要性。优秀的数学教师,都格外重视练习的质量,依托有效的练习,来提高学生的学业成绩。一般的数学授课中,几乎是堂堂练,天天练。练习可以有力地促进学生对数学知识的掌握,巩固对概念、法则、公式、定律、性质的理解,提高对数学知识的运用能力。那么,怎样设计练习题呢?一、相同条件,提出多个问题就相同的条件,提出多个问题,让学生解答,可以提高学生的发散能力和多渠道解决问题的能力,有利于学生智力的成长。一题多问可以采取正面求问,也可以逆向求问,还可以假设求问。在设计练习的时候,除了老师设问,还可以鼓励学生发问,针对一定条件,命出问题, Mathematics teaching places particular emphasis on the importance of practice. Outstanding math teachers all attach great importance to the quality of exercises and rely on effective exercises to improve students’ academic performance. The general mathematics teaching, practicing almost, practice every day. Practice can effectively promote students mastery of mathematical knowledge, consolidate the understanding of concepts, laws, formulas, laws and nature, improve the ability to use mathematical knowledge. So, how to design exercises? First, the same conditions, put forward the same conditions for multiple questions, put forward a number of questions for students to answer, can improve the ability of students to divergent and multi-channel problem solving, is conducive to student intelligence growing up. If you ask more questions, you can ask positive questions or you can reverse questions. You can also ask questions. In the design practice, in addition to the teacher asked questions, you can also encourage students to ask questions, for certain conditions,
