关于中等职业技术学校开设环境教育课程的建议 总被引:1,自引:0,他引:1
在“环境保护,教育为本”的思想指导下,我国已把环境教育列入九年义务教育课程大纲,真正做到从娃娃抓起,极大的提高了全民族的环境意识。但是,中等职业学校的环境教育仍是一个薄弱环节。一方面每年少量的环保类专业毕业生尚不能满足环保岗位自身的需要 ,另一方面大多数中等职业学校非环保专业几乎没有开设有关环境教育的课程。据我们调查及反馈的信息表明:中专生非环保专业的学生对环境保护的认识大多数来自媒体,而且认识较为粗浅,对环境问题及可持续发展战略关系及环保法规政策没有一个比较系统、深刻的理解 。根据多年的教学实… 相似文献

目前,在各级各类的教育体系中,如小学、中学、中等职业教育及高等教育,都相应开展了环境教育工作。其中小学、中学及高等院校的环境教育,开展得比较普及,其教育也较系统与规范,国内外在这方面的报道也较多。但中等职业的环境教育还处于探索阶段,虽然取得了一些效果,但总体上没有形成一种系统的整体的成熟的教育系统。在这一次全国范围内的中等职业学校环境教育调查中,既有经济比较发达的沿海地区的城市,也有经济欠发达的内地城市,既考虑了现代化的大都市,也选择了一些中小城市,共对 50余所中等专业技术学校,将近 3000名学生进… 相似文献

自2000年召开“全国绿色学校表彰大会”以来,上海市环境教育工作继续坚持高标准、严要求,又新创建了50多所绿色学校,目前,上海市的绿色学校总数已超过200所,其中3所全国绿色学校,36所市级绿色学校和170所区、县级绿色学校。以“绿色学校”为抓手,进一步拓展环境教育课程建设上海在探索确立学校环境教育渠道的过程中,以“可持续发展”战略思想为教育目标定位,分主渠道、辅渠道两大块,分别包含必修、选修及活动若干科目或项目来进行。并注意几个要点:一是列入主渠道的学科教学目标要与环境教育目标有响应性;二是要通过课程的多领… 相似文献

丹东市农业学校是一所普通中专,原主要开设专业是种植业和养殖业。 1995年,根据环保事业发展的需要新开设了环保专业,并成立了环保专业科,旨在培养环保专门人才。笔者作为环保专业教师,在从事环保教学的同时,通过参加互动式环境教育培训班学习和培训,更加深了对非环保专业中专生环境教育的紧迫感。然而笔者注意到,在全国各地广泛兴起的创建绿色学校活动,参加者几乎全部是中小学校。而惟独少见中等职业教育学校。难道中等职业教育学校不需要环境教育吗 ?对此,本人认为中专学校环境教育滞后的原因可能是多方面的,各地、各校也不同… 相似文献

Trametes versicolor decolorized 2000 mg L(-1) of the mono-azo substituted naphthalenic dye Amaranth with no dye sorption observed visually. The changes in the toxicity were assessed over a period of 30 d for the dye-treated viable culture, control (no dye added), and a boiled culture treated with dye, using the Microtox Acute Toxicity assay. Before dye addition, the culture filtrate had some toxicity, which increased after the dye addition. The toxicity of the dye-treated culture decreased during the treatment. The loss of toxicity occurred at the same time, with the loss of color suggesting that detoxification is associated with decoloration. The change in pH was due to natural metabolic processes and had a small effect on detoxification. Because the toxicity of the treatment was similar to that of the control at the end of the treatment, the effluent seems to be safe for release into the environment, potentially rendering this treatment suitable for industrial application. 相似文献

ABSTRACT Estimation of State of Health (SoH) of Lithium-ion (Li-ion) battery is essential to predict the lifespan of batteries of an electric vehicle (EV). The efficient prediction of battery health indicates to the effective and safe operation of EV. However, delivering an effective and accurate method for the estimation of SoH in the real condition is truly a challenging task. The present study proposed a holistic procedure of combining both experimental and numerical investigations to conduct the fundamental study on coupled mechanical-electrochemical behavior of Li-ion battery. The proposed investigation highlighted the effect of stress on the capacity of the battery, considering capacity fade as an equivalent parameter to its health for real-time estimation of SoH. Finally, a simple model of Artificial Neural Network (ANN) is provided, which shows the linear dependency of stress with the SoH. The results obtained from the ANN model are validated with a Linear Regression (LR) model for a better understanding of the inspection. The predicted value of mean Square Error (MSE) and R square error in the ANN training model are found to be 0.000309 and 0.849687, respectively. Whereas for the test model, these predicted values are found to be 0.000438 and 0.819347, respectively. 相似文献

A previous study using respondents in a London regional audience appreciation diary panel showed that links existed between overall amounts of the viewing of television recorded across one week and levels of perception of risk of three hazards to life, namely lightning, flooding and terrorist bomb attacks. With a fourth hazard, cancer, there was an inverted U-shaped relationship between perceived risk level and amount of viewing. At the same time there were no relationships between amounts of viewing of news and documentary material and perceived risks of any of 12 hazards. Two new surveys were done, nearly three years after the previous one, asking people in widely different regions about their perceptions of nine various hazards, and linking these results with measures of attitudes towards certain adaptations of new technology (which could prove hazardous or beneficial according to points of view) and to patterns of television viewing. The two surveys agreed on a wide number of points with each other; they agreed with the previous study in finding no steady relationships between information programme viewing and hazard perception. Lightning and flooding were again related, this time more specifically with viewing of particular types of television programming. A new finding is that heavier viewing of television sport is associated with less perceived risk of cancer and of nuclear pollution. Interpretations are generally favoured along the lines of a selective process of viewers with certain predispositions choosing certain kinds of viewing patterns, rather than that programme contents provide an example for formulating perceptions and attitudes. 相似文献
