在小学一年级语文识字教学中开辟“纠错板”的实践研究

众所周知,汉字是我们开展认知活动、学习活动的基础,也是我们获取知识的重要载体。因此,汉字教学是最基本也最重要的一个教学板块。为了让学生们的基本素质、基础素质更为坚固,老师就需要给予识字教学足够的重视与关注。而“纠错板”作为一种有效的识字教学工具,它能够让识字教学活动的开展过程更加顺利。

在语文识字教学中开辟“纠错板”的实践研究

在小学语文课堂中,语文教师在课堂中最重要的授课重点是对识字的学习与传授。然而,由于一年级小学生在学习识字上存在着外在与内在因素的影响,造成课堂上的知识掌握不牢靠。主要原因是学生不能记住汉字,混淆汉字。对于这个问题我们选择了"纠错板"的方法。本文对小学一年级语文教学中开设"纠错板"的实践进行研究与分析。

Determining the approach speed envelope of carrier aircraft

Many factors,such as deck motion and air wave,influence the determination of the approach speed which has an important effect on landing safety. Until recently,there are no design criteria about approach speed of carrier aircraft in the current standards and available publications. Therefore,the requirements of stall margin, longitudinal acceleration ability,altitude correction and field-of-view on approach speed were researched. Based on the flight dynamics model,the flight simulations were conducted to study the effect of the response time of engine,wave off requirements,elevator efficiency and deflection rate on the approach speed. The results presented that the approach longitudinal acceleration and altitude correction ability had crucial influence on the approach speed envelope of the aircraft. The limitations of the control requirements,field- of- view requirements and gear were also given through the simulation and analysis. Based on the above results,the approach speed envelope were determined.
