生命中的一课

<正>任何事情的发生都是有原因的,没有什么事是纯粹出于巧合或机会的好坏而发生。疾病,伤痛,爱情,曾经的荣耀和愚蠢的事,所有这一切的发生都是对你灵魂的考验。如果没有各种各样事情的发生,疾病或关系的考验,生活将会像一条已被铺就却没有目的地的平坦小路。如果有人伤害了你,欺骗了你,让你心碎,原谅他们吧!至少他们让你学会了如何信任他人,他们让你懂得当你敞开心扉与人交流时,谨慎是多么重要。     

把平凡的事做到最好

路遥是我所佩服的作家。他的小说犹如黄土地般厚重,他笔下的人物往往有一颗淳朴的心。《平凡的世界》是路遥最著名的长篇小说,曾经获得茅盾文学奖。作者以孙少安和孙少平两兄弟为中心,刻画了社会各阶层众多普通人的形象。他们的日

每当我遇到挫折时,母亲就会说:"一切都会好的。如果你坚持下去,总有一天会有好事发生。你会认识到,如果没有以前的挫折,就不会有现在的一切。"母亲是对的,发现这个时我刚大学毕业。我已决定试着在电台找个事儿做,然后争取做体育节目的播音员。我搭便车到了芝加哥,一家电台接一家     

塔德波尔——一个学生的第一课

意识到那一天将是多么重要,我简直无法入眠。昨天,妈妈在麦金利小学为我办理了入学注册。我的年龄终于够了,可以与所有其他的大孩子一起上学了。我自幼儿起就已经认识了字母表与数字,但我盼望着学会阅读,这样我就能独自看故事书。更重要的是将会与别的孩子在一起玩耍。我穿第一天上学时的衣服时,闻到了油煎熏猪肉的味道,就匆匆下楼了。

Problems, perseverance, and mathematical residue

This paper reports on a qualitative study in which three third grade students were presented with a mathematical challenge related to the volume of a cuboid. The task required the construction of containers and the enumeration of the multi-link cubes¹ held by each of the containers. The study videotaped and investigated the students working as a group through potentially seven different problem solving categories, and how they dealt with the student-generated mathematical dilemmas that surfaced during their exploration of the original problem. The tapes were examined for the problem solving actions that the students demonstrated, and an analysis of the students' counting strategies and solutions explored the connection between the children's spatial structuring and their use of numerical operations in enumerating 3-D rectangular arrays of cubes. The notions of perseverance and control are considered as they emerge during autonomous problem solving and the mathematical residue that results from the developing understanding of volume is discussed.This revised version was published online in October 2005 with corrections to the Cover Date.     

词义的坚守与游离 --语境与语义关系谈

词语之所以表情迭意,是和语境不相分离的。词义在一定的概念范围内游离,一旦它进入到某一特定的语境中,它的具体意义才能较为确定和清晰。因此,词义是游离的,只有在一定的语境制约下才能坚守。     

理想的大学英语课堂:“心流”体验课堂

心流是一种理想的体验状态,当心流出现时,身心会高度集中,行动与回馈将不断互流,乐趣则油然而生。心流体验对于学习者有积极的影响,可以全方位提升学习绩效。通过研究心流的含义、构成要素及模型,掌握心流产生的内在规律,对于现代课堂教学具有重要的意义。在设计大学英语课堂时,把这种心流状态考虑进去,构建适用于大学英语课堂的心流模型,便可以使教学效果达到最优化,打造理想的大学英语课堂:心流体验课堂。     

A study of emerging teacher practices in internet-based lesson plan development

In this paper we describe two aspects of an Internet-based lesson plan development project called Science On-Line-Earth and Space Science for the Classroom. First, we discuss the design of the Science On-Line (SOL) Project, which focuses on building a community of practice, appropriate task and setting, and contact with the scientific workplace. Second, we examine strategies teachers used as they approached the task of creating Internet-based science lesson plans for the World Wide Web. Based on the analysis of data gathered during the various project phases, results show that the teacher-developed strategies have varying degrees of effectiveness in facilitating Internet-based lesson plan design, information-gathering, and organization. We describe how the strategies began to evolve into formulated practices for Internet-based lesson development within the SOL teacher community. The SOL investigation develops a case study of the strategies and emerging practices in the context of the creation and pilot-testing of Internet-based lesson plans. This case study may serve as an exemplar of tested Internet-based lesson development strategies and practices for the educational community.     

一堂有趣的数学课

一天,美国斯坦福大学商学院的数学教授库珀让同学们把自己的生日写在小纸片上,然后把所有的小纸片都折起来放在讲台上。他拿出一张5美元的钞票,问:我用5美元打赌,你们中至少有两个人同月同日生,有人敢跟我赌吗?我赌!3个男同学举起手来,另外七八个同学也掏出5美元扔在桌子上。
