The future is bright for human performance technology

At the 1997 ISPI Conference in Anaheim, Dale Brethower, Don 1'osti, and Danny Langdon presented a dialogue on “Performance Technology: The Future of Technology and the Profession.” In the July issue of Performance Improvement, we heard Danny Langdon's thoughts on this topic. This article represents Dale Brethower's contribution to the dialogue. We will hear from Don Tosti in an upcoming issue.     

孩子太听话不一定是优点

在很多家长和教师的心目中,听话的孩子就是好孩子.我们经常听到这样的叮嘱: "你要听话,知道吗?""你真乖!"我们很习惯于下"定义"--不听话的孩子叫作顽童,听话的孩子就是乖孩子.我们培养了很多听话的孩子,但是孩子太听话却不一定是优点.     

"孝敬"不仅仅是词--《东京故事》观感

A poor lonely old couple sat side by side by the railway wondering where to go and where to sleep at night,eyes full of disappointment and sadness,and only had some biscuits to eat for supper, will their children burst into tears and thoroughly reform themselves to become filial?I don't know.But I cried when I watched the film Tokyo Story.I cried for the pitiful couple who have endured all kinds of hardships but were abandoned by their own blood relations,cried for the blameful children, cried for the soft-hearted but hard-lucky daughter-in-law…     

阿尔都塞的结构主义者性质质疑

通过考察阿尔都塞思想的三个渊源，发觉阿尔都塞不仅继承了结构主义的思想和方法，而且还吸收了巴歇拉尔历史认识论和斯宾诺莎唯理论的某些思想观点。与其说他是一个结构主义者，不如说他是一个“唯科学主义者”更为合适。     

A good sub is hard to find: Establishing a substitute referral system

Finding and keeping good substitute child care workers is a problem that touches everyone in the field: teachers, administrators, resource and referral workers, and of course, the subs themselves. This article is addressed to all these groups in the hope that coordinated efforts can lead to better practices and new solutions. Below, you will find information on what's causing the substitute crisis and how community agencies around the country are responding.This article is excerpted from the bookletA Good Sub is Hard to Find. To order copies please write: Child Care Employee Project, P.O. Box 5603, Berkeley, CA 94705.     

A hint is not always a help

This paper discusses the construction of hints for mathematical problems and their effectiveness. From a set of 15 non-standard problems on functions every problem was presented to a hundred ninth-grade students (age about 15). Hints might be used if necessary. Hint effectiveness was studied as a function of hint characteristics. The following results were obtained: Hints which stimulate concrete action are effective, if the action serves as a model for the required solution method. Hints which give only warnings against certain mistakes are ineffective. Hints which show a great part of the solution of a problem seem to be effective; however the solution was often reached with lack of understanding. The results are compared with results obtained by Trismen (1981, 1982).     

三星堆器物坑不是祭祀坑

三星堆发现的两个器物坑,长期被误为祭祀坑。限制了对三星堆文明的深入研究。近来发现了一号坑向外延伸的坑道的作用,彻底否定了祭祀坑说。从而使三星堆三期文化中器物形成的时间向早期推进,延伸出更大的研究空间。     

高等教育不仅仅是一门学科

高等教育学科理论建设具有极其重要的意义。但是,在群众性高等教育研究大发展的形势下,我们应该倡导高等教育研究的多元化发展;在高等教育研究制度化进程中,应突出高教研究的“知识转向”与知识生产属性,尊重、生产、传播或利用各种有价值的以各种形态存在的知识成果,通过建构包括学科知识在内的多元知识生态系统,共同促进高教改革、发展与学术领域的繁荣。     

岳州关不是“洋关”

自1899年11月13日岳州开埠、城陵矶设关、1901年城陵矶海关三座"美轮美奂"的关房建成后,民间便因海关税务司等是洋人,而称其为"洋关"。但岳州关并非"洋关"。因为湖南轮运为湖南人首开,岳州是自开口岸,城陵矶海关关房是中国人自己出资修建的,海关税务司由外人担任是历史造成的。     

由“韩寒现象”引发的思考———“韩寒现象”不只是文化现象

“韩寒现象”中的韩寒代表了现今一部分某一方面有特长的学生的另类式的发展模式。“韩寒现象”是一种多元化价值取向的文化现象, 同时也是一种教育现象和敢于反叛与创新的社会现象。

数字逻辑实验技术改革的研究

分析了传统的基于中小规模集成电路的实验技术的弊端;提出计算机专业的"数字逻辑"课程应该采用基于VLSI的EDA实验技术,并且用设计性实验取代验证性实验;开发了数字逻辑设计性实验课题;研究出了改革方案并在教学实践中取得好的效果;基于VLSI的"数字逻辑"实验技术用硬件描述语言进行逻辑设计,用软件仿真来检验逻辑设计是否正确。
