西部农村学校化学实验教学现状调查分析——兼谈教研方式的转变

在对巫山县农村学校化学实验教学现状深入调研的基础上，针对新课程实验教学中的主要问题进行分析，提出了加大经费投入，改善实验条件；强化专业培训，提升队伍素质；加强制度建设，规范实验管理；转变教研方式，提高教学效率等改进农村学校化学实验教学的可行建议。

对化学实验工作的思考

高中必修化学教材中增加了大量的课堂探究实验,这将使教学模式发生改变,对学校的实验工作也提出了更高的要求。因此,强化实验工作意识,加强对学校实验工作的管理,特别是教师观念的转变、实验员的培训是亟须解决的问题。

Waste Minimization Practices at the National University of Costa Rica

In order to determine the quantity of laboratories doing waste minimization practice related with the USEPA （United State Environmental Protection Agency） pollution hierarchy, an initial diagnostic about waste management at laboratories was conducted. The data gathered were used to start a training to laboratory personnel training about EPA-PH （Environmental Protection Agency-Pollution Hierarchy）. After training new diagnostics were performed. The applications of waste minimization practices in the laboratories were analyzed before and after the training. The most poorly practices performed year by year during the study period were ＂substitute nonhazardous materials＂, ＂chemical treatment＂ and ＂distillation＂. ＂Redistribute surplus chemical＂ was performed in 22 labs, 30 labs and 48 labs during years 2010, 2011 and 2013 respectively as the most common practice. This study showed that training about pollution prevention hierarchy increased the number of laboratories doing waste minimization practices, prioritizing reduction and prevention from the source.
