美国约翰霍普金斯大学化学系教学实验室访学见闻

介绍了对美国约翰霍普金斯大学化学系教学实验室访问学习见闻。通过访问学习,发现其系统全面的实验室安全教育方式、行之有效的实验室安全管理措施、实验室垃圾与生活垃圾的分类处理办法及网络辅助实验教学模式、注重学生课堂实验笔记的实验课成绩评定方式等方面,都值得我们学习和借鉴。     

化学课堂探究教学“制订计划”的评价

为了解化学课堂探究教学“制订计划”的有效性,在课堂观察与分析的基础上,提出化学课堂探究教学“制订计划”系统分析量表,并结合具体化学课堂探究教学,从计划制订的主体、计划制订的过程、计划内容本身等3个方面解析了“制订计划”环节。结果启示：化学课堂探究教学“制订计划”系统分析量表能科学有效地指导化学课堂探究教学,特别是其“制订计划”的设计、实施与评价。     

高中生盐类水解心智模型的研究

采用二段式测试与半结构化访谈法对学生关于“盐类水解”内容的学习进行探查,了解学生盐类水解的定义与本质、水解反应方程式的书写、盐溶液的酸碱性的判断、盐类水解的影响因素、盐类水解中3大守恒定律的应用、盐类水解的应用等6个主题的心智模型,包括样例依存模型、概念混淆模型、思维定式模型、宏-微-符认知偏差模型等,并给出了相关的教学建议。     

The EcoScale as a framework for undergraduate green chemistry teaching and assessment

An upper-year undergraduate practical examination is presented that utilizes the EcoScale (a semi-quantitative tool) and several established mass metrics to assess student understanding of green chemistry principles. This activity focuses on the straightforward preparation of a benzodiazepine via three different catalytic methods, and the analysis of individual experimental data during laboratory time. Students learn about the structure of the EcoScale, apply it as a simplistic life cycle assessment, and critique it as a scientific model. The examination complements more traditional expository and self-design experiments within a synthetic course where green chemistry and sustainability are central themes.

机械采油实验室测控系统的实现

运用液压技术、传感器技术和计算机测量控制技术建成的“机械采油实验室”,能模拟石油开采过程中的井下环境,通过对模拟机械抽油机运动的控制以及对井下各种环境的控制过程,测量出抽油机的运动规律和机械出油量,以期研究机械采油环境和采油效率。该技术在石油工业应用中有着优良的前景;运用在线(on-line)方式修正控制参数,具有一定的准实时性,控制效果良好。通过比较几种运动规律下的采油效率,给提高实际采油效率提供参考方法。     

我院学报论文的引文统计与分析

本文以引文率作为测度的标准,对1986～1990年期间我院教师、科技人员发表在《洛阳工学院学报》上的论文的引文进行一次初步的统计,分析其数量、类型、语种、时序等的分布,较为准确地反映了我院教师、科技人员利用文献资料的情况。     

Air handling in clean laboratory environments: the reason for anomalously high boron background levels

The isotopic analysis of boron from material that carries only trace amounts of boron requires low boron blank levels. Large efforts are taken to keep blank levels low by purifying reagents. We performed exposure experiments and determined procedure blanks before and after the air-handling system was modified from silicate glass filters to polyethylene/polystyrole and active carbon filters. Our investigations demonstrate that the air-handling system may be the major source of boron blank in many laboratories, as the widely used silicate glass filters, which contain boron as a major component, in the form of borax and boric acid, release significant amounts of boron to the air.     

Regulatory compliance vs. NEXUS quality for laboratory tests

In the U.S., all clinical laboratory testing is regulated by the Clinical Laboratory Improvement Amendments (CLIA) (). The CLIA link test quality and adherence to a body of testing regulations intended to ensure accurate, reliable, and timely patient test results. The goal of the CLIA legislation was to ensure a minimum, fundamental level of quality. In the context of “NEXUS,” quality must “go beyond getting the ‘right’ answer on the ‘right’ patient that can be interpreted against ‘right’ reference values. CLIA regulations with specific minimum, performance requirements, or safeguards, are designed to prevent testing errors. The US Institute of Medicine found that testing processes fail as a result of human error, lack of documentation, and lack of test management. In the latest (2004) interpretations of CLIA regulations, the minimum quality control requirement continues to be analyzing at least two external, liquid quality control materials per test per day. In 1995, we proposed that the responsibility for achieving quality test results shifts from the sole purview of the laboratory director to an “alliance” of laboratory professionals, manufacturers, and regulators. The EQC (equivalent quality control) concept as proposed is a positive step in achieving this alliance. With the obvious lack of scientific and statistical robustness, EQC falls far short of ensuring quality. Achieving the “NEXUS Vision” for quality laboratory testing will not come solely from laboratory professionals. The NEXUS is about how to ensure the full-quality assessment of the testing process – pre-analytical, analytical, and post-analytical.Presented at the 10th Conference Quality in the Spotlight, March 2005, Antwerp, Belgium.
