高等医学院校大型教学实验中心的管理实践

医学实验教学长期以来是依附于学科的单一模式，实验室是三级管理体制，已不适应现代医学模式转变对医学教育的要求。介绍该校于1997年成立东校区大型科学实验中心，通过改革体制、科学管理、深化改革、突出效益、服务育人等措施，经过3年的管理与实践取得了明显成效。     

高等师范院校计算机基础教育的现状与对策

从高校计算机基础教育的目的出发,结合笔者的教学实践,对高等师范院校计算机基础教育的现状进行了分析,在教学方法、教学内容、教学模式等方面提出了几点改革建议.     

Mastery,insight, and the teaching of chemistry

The learning of chemistry is described as a process analogous to the process of making chemical discoveries. Historical examples are given to show how chemists have used their insight to break out of a conceptual loop in order to advance the science. Having the insight to make the intuitive leap necessary to break a conceptual loop is as important as having the mastery of the pertinent facts. As in making chemical discoveries, learning elementary chemistry requires developing insight as well as acquiring mastery of the facts. However, current general chemistry teaching tends to teach facts first and insight later. Suggestions for improving this situation so that insight and facts are learned together are given. Finally, the nature of insight is probed more deeply and presented as a two-step process where the first step is an evaluation of the perceptions about science which are held. Once the student, teacher, or researcher has a clear evaluation of the validity of the perceptions that he or she holds, further significant progress toward understanding or scientific discovery is possible.     

注重共性中的个性教学

自然科学所遵循的基本规律是事物内在本质决定的。但任何规律也必须是辩证的。不能将其公式化。在化学教学中，要求学生掌握普遍规律的同时，注重普遍性中的特殊性同样重要。以初中化学中违背基本规律的几个典型问题为例，强调在突出共性教学的同时注重个性教学。     

化学教学中的环境教育

公众的环境保护意识的水平高低,直接关系到我国环境保护事业的成败,而提高公众环境意识、培养公民的环境道德,最主要的途径就是开展环境教育;阐释了环境教育的必要性,并就化学教学自身,分析如何结合教材内容进行环境教育、结合化学实验进行环境教育、在课外活动中进行环境教育,以培养学生的环保意识。     

Double Jeopardy: Testing the Effects of Multiple Basic Skill Deficiencies on Successful Remediation

Prior research has established that the depth and breadth of remedial need in basic skills (math and English) exhibited by a student at college entry are strongly and negatively associated with the likelihood of achieving college-level competency in those subjects (i.e., successful remediation). This well-documented finding is built upon a body of work employing either simple bivariate analyses or regression analyses that assume additive effects. Yet, there are reasons to suspect that multiple basic skill deficiencies, rather than exhibiting additive effects alone, may exhibit a negative multiplicative interaction effect on the likelihood of successful remediation. In this research, I test the hypothesis that the negative effect of math deficiency increases in magnitude with decreasing English competency. Although the data support this hypothesis, I find that this interaction does not have substantive importance in the face of the powerful direct effect of math deficiency on the likelihood of successful remediation in math.

I am indebted to Tim Brown, Willard Hom, Myrna Huffman, Tom Nobert, Mary Kay Patton, and Patrick Perry of the Chancellor’s Office of California Community Colleges for their assistance with the data employed in this study, and to Dr. John C.

试论课程三维目标

课程目标是当前基础教育课程改革中涉及的基本问题。课程三维目标的提出是现代社会发展的需要，也是人自身发展的需要。三维目标与双基目标既有区别，又有一定联系。课堂教学改革应围绕三维目标的落实而展开。     

新课程理念下实验在化学教学中的运用探讨

文章探讨新课程理念下实验在化学教学中的重要作用、发展现状以及有效应用策略,强调实验教学要激发学生兴趣、优化实验流程、鼓励小组合作、结合课内实验和课外活动。     

试论化学实验教学中引导学生进行探究性学习

化学实验是化学学科的重要组成部分,需要顺应新课改的要求,重视实验教学内容与教学方式的改革。针对化学实验教学存在的主要问题,文章研究化学实验教学中引导学生进行探究性学习的策略。要采用情境教学模式,激发学生探究兴趣;指导学生假设与猜想,深入探究事物的本质;引导学生合作交流,优化化学实验探究功能。
