制作CAI课件时,要明确制作目的,做好选题策略,规范课件的制作程序.     

工科数学课件制作与教学实践初探

教育技术的多媒体化与网络化,及其在教学上应用与研究是当前教学改革的热点.利用先进的软件工具,制作实用的课件并应用于教学是改变教学面貌,加大课堂信息量,发挥学生主体作用,提高教学质量的有效手段.本文从自制工科数学教学软件、课堂教学受益及使用启示三个方面进行初步探索.     

When Routines are Not Enough

Interest in crisis management among journalism scholars grew in the wake of the terror attacks of September 11, 2001. Yet, few studies explore journalists and their organizations from a newsroom and organizational crisis management perspective. In this study, we study journalists’ ability to conduct news work when faced with a frame-breaking news event—in this case, the July 22, 2011 attacks in Norway. Dividing the journalistic response to these events into three stages, each with its own particular challenges, we have been able to unpack how these Norwegian journalists were capable of reporting on the events despite the chaos and uncertainty that followed in their wake, including the fact that the newsroom itself suffered severe damage from the bomb blast. This study shows that coping mechanisms in times of organizational stress will range from the expected (routine, habit) to the unexpected (improvisation, bricolage). The individual must pick up where the organization leaves off, relying upon experience and professionalism as well as face-to-face interaction and the assistance of whatever technology survives.

讲解与示范在体育教学中的应用

在体育教学中,为使学生尽快建立正确的技术动作的表象和形成的思维概念,教师在教学实践中如何应用讲解与示范是完成教学任务的关键.     

体育教学过程中的语言形式

体育教学与其它教学一样是教与学的双边活动,但它又有不同于其它学科的特点,具有特殊的认识过程,体育语言是体育教师组织教学的桥梁,它直接影响着教学的效果,对完成教学任务有着重要作用.     

论20世纪中国文学中的畸人形象

《庄子》中塑造了大量的畸人形象,可分为两类：一类是身体上的残疾人;一类是心理变形的疯子。20世纪中国文学中也有这两类畸人形象,可看作是对《庄子》中畸人形象所表达的主题思想、文化意义等的继承和发展。     

The effects of background television on the toy play behavior of very young children

This experiment tests the hypothesis that background, adult television is a disruptive influence on very young children's behavior. Fifty 12-, 24-, and 36-month-olds played with a variety of toys for 1 hr. For half of the hour, a game show played in the background on a monaural TV set. During the other half hour, the TV was off. The children looked at the TV for only a few seconds at a time and less than once per minute. Nevertheless, background TV significantly reduced toy play episode length as well as focused attention during play. Thus, background television disrupts very young children's play behavior even when they pay little overt attention to it. These findings have implications for subsequent cognitive development.
