《数学课程标准(2011版)》指出:“数学活动经验的积累是提高学生数学素养的重要标志。帮助学生积累数学活动经验是数学教学的重要目标……数学活动经验需要在‘做’的过程和‘思考’的过程中积淀……”小学生由于其年龄和认知特点的限制,很多时候他们从观察、操作、猜测、推理、抽象等各种数学活动中获得的只是一种经历或体验,这种经历或体验往往只是教学的起点,还需要在教师指导中去伪存真、去粗取精,才能从现象走向本质、从肤浅走向深入,才能积淀
The Mathematical Curriculum Standard (2011 Edition) states: “The accumulation of experience in mathematical activities is an important indicator of improving students’ mathematical literacy and helping students to accumulate experience in mathematical activities is an important goal of mathematics teaching ... Experience in mathematical activities needs to be done Process, and thinking ... ”Pupils often find themselves in a variety of mathematical activities such as observation, manipulation, guessing, reasoning, abstraction, etc., because of their age and cognitive characteristics, or Experience, this experience or experience is often just the starting point for teaching, but also in the guidance of teachers to fake excesses, to crude and refined, in order to move from the phenomenon to the essence, from the superficial to the depth of accumulation

摘要:本文通过新疆石油产业的发展现状和石油产业对新疆区域经济的投入产出效应以及产业关联效应等影响力的分析，结果表明：新疆石油工业的投资对新疆固定资产投资的拉动力度较大；石油产业对区域GDP和工业总产值的直接拉动作用也比较明显；对其他行业的需求影响较大，但对地方工业辐射作用和拉动作用相对较弱；同时对区域经济增长的直接贡献及其通过外溢作用而产生的间接贡献不太显著。 关键词：石油产业；影响力；区域经济

《数学课程标准》指出:“数学教学是数学活动的教学,是师生之间、学生之间交往互动与共同发展的过程。”师生对话是课堂教学的主要的交流互动方式,但是,现实的课堂中,教师说
“角”的知识,对低年级小学生来说是一个很抽象的数学概念,如何让学生理解,并能掌握它的数学内涵,对教师是一个挑战。最近听的一节有关“认识角”的课中,发现一个现象值得思
