循序渐进搞好研究性教学

研究性教学改变了传统的教学模式，它有利于培养学生的能力，但是学生的研究能力不是天生的，教师应该循序渐进地进行培养，将启发式、由浅入深、讨论式等传统的优秀教学方法与研究性教学有机地结合起来．

A virtual environment for process management. A step by step implementation

In this paper it is presented a virtual organizational environment, conceived with the integration of three computer programs: a manufacturing simulation package, an automation of businesses processes (workflows), and business intelligence (Balanced Scorecard) software. It was created as a supporting tool for teaching IE, its purpose is to give professors and alumni the possibility to practice and apply the concepts and knowledge of IE learned at school since the very beginning of the program. This environment allows perform many business processes functions of management; it is already running in both, Local Area Network and Internet. With this system running in a network, it is emulated the functioning of an organization, in which it is necessary a coordination of multiple actions for making decisions in a collaborative and integrated manner. The work developed in this virtual atmosphere permits the participants to face non structured problems, and also it is possible to develop their own skills and aptitudes for being a good professional. The Virtual Enterprise is managed by a Management Committee, formed by high level alumni and invited professors; they have the responsibility of achieving the productivity levels necessary to its own economic profit. The Intermediate courses alumni are in charge of the resources evaluation utilization. The lowest level alumni are in charge of Data Acquisition and feeding the Data Base. The Virtual Enterprise compromises the Industrial Engineering School as a whole, and all the students feel their belonging since the first courses, it motivates them to search for the knowledge and desire to be an Industrial Engineer.     

微格量化实验成绩，提高有机化学实验教学质量

从培养教师的角度看,化学实验教学应注重学生实验操作的规范性和培养动手能力。为此,我们在有机化学实验教学中进行了微格量化实验成绩的探索,取得了较好的效果。

SSTM:一种基于西部基础差学生的分步式教学方法

西部高校部分学生学习基础较差,针对这部分学生的课堂教学难以用常规的教学方法进行,作者旨在找到更适合的教学方法解决这一难题.主要工作包括:定义了难度系数(D(a))、正确率(R(n,m))等概念,提出了分步式教学法并证明了相关定理.对采用分步式教学法和未采用分步式教学法的学生进行了实验对比,实验表明:采用分步式教学法的学生中回答问题的正确率要高出33％,完成实验报告的正确率要高出29％,回答问题的准确率要高出50％.因此,分步式教学法是有效的教学方法.

The next step for literacy

The world community committed to support universal access to basic education in 1990. Since then, schools have been built and teachers hired and trained. Twenty years later, many more students were in primary school, but learning assessments showed that most were not learning how to read well enough to use reading to learn. The world community turned its attention to improving instruction. As instruction improved, more students could decode words and read with improved speed and accuracy. However, reading comprehension was still low. Now is the time for the world community to come together and make a commitment that all students will learn to read with sufficient comprehension to use reading to learn.

Establishing word-object relations: a first step

This work explores how infants in the early phases of acquiring language come to establish an initial mapping between objects and their labels. If infants are biased to attend more to objects in the presence of language, that could help them to note word-object object pairings. To test this, a first study compared how long 18 10-14-month-old infants looked at unfamiliar toys when labeling phrases accompanied their presentation, versus when no labeling phrases were provided. As predicted, labeling the toys increased infants' attention to them. A second study examined whether the presence of labeling phrases increased infants' attention to objects over and above what pointing, a powerful nonlinguistic method for directing infants' attention, could accomplish on its own. 22 infants from 2 age groups (10-14- and 17-20-month-olds) were shown pairs of unfamiliar toys in 2 situations: (a) in a pointing alone condition, where the experimenter pointed a number of times at one of the toys, and (b) in a labeling + pointing condition, where the experimenter labeled the target toy while pointing to it. While the pointing occurred, infants looked just as long at the target toy whether or not it was labeled. During a subsequent play period in which no labels were uttered, however, infants gazed longer at the target toys that had been labeled than at those that had not. Thus language can increase infants' attention to objects beyond the time that labeling actually occurs. These studies do not pinpoint which aspects of labeling behavior contribute to the attentional facilitation effect that was observed. In any case, however, this tendency for language to sustain infants' attention to objects may help them learn the mappings between words and objects.
