新教材中有关"讨论"的思考 总被引:1,自引:0,他引:1
将“讨论”列为新编全日制普通高级中学化学教科书 (实验修订本·必修 )的构成成分 ,是中学教育教学中实施素质教育的重要举措之一 ,实施开放性化学教育教学 ,培养学生能力的重要方面。可见 ,只有领会“讨论”的编写意图 ,明确其功能 ,才能落实“讨论”这一重要环节。1 关于“讨论”的特点纵观新教材 (以第一册教科书中的内容举例说明 )中的“讨论”内容 ,其设置从总体上具有以下特点 :1 1 “新课引入型”讨论在第一节 :氧族元素 (p12 5 )中的“讨论” ,共设置3个小问题 :①根据图 6— 1和表 6— 1分析 ,氧族元素原子的核电荷数、电子层… 相似文献

本科化学教育新体系的研究与实践 总被引:3,自引:0,他引:3
1 把一个本科化学教育新体系带入 2 1世纪1 .1 办学经验与存在问题 从新中国成立算起 ,我校化学专业办学已超过 50年了。化学院继承和发扬了老中大的传统 ,历届院系领导重视基础教学 ,狠抓“三基”(基础理论、基础知识和基本技能 )教学的结果 ,使培养的学生基础扎实 ,适应性强 ,到了工作岗位显得有后劲。这是我们办学和培养人才的基本经验 ,从历次毕业生跟踪调查反馈回来的信息和许多学生出国留学国外同行反映的意见中可得到验证。然而我们在对学生的培养过程中 ,“三基”教学的内容大都是教师通过采用演绎法教学系统地传授给学生 ,这… 相似文献

Green chemistry is also called environment harmless or environment friendly chemistry.Green chemistry requires to use new synthetic methods, engineering technologies and processes to eliminate or reduce by-products, wastes or products that harmful to human health, community safety,and ecology environment. Green chemistry pursues to control the usage of the harmful and toxic materials, reduce waste emission, avoid necessity to treat the wastes; Green Chemistry advocates wastes management from the beginning, improving the efficiency of atoms, optimizing the use of resources and energy, lowering the cost of production. Green Chemistry technologies are the ultimate path to the clean chemical production in the future.Insight Co. takes "hospital of enterprises" and "bank of technologies" as our characteristics in business, and deems the development and spread of green chemistry as our mission. We developed an unique business model which combines education, research and production. In the past 8 years,we had applied and obtained more than 30 patents and received more than ten national and provincial awards in technology progress.We had made great progress in the manufacturing of organophosphorus pesticides, especially the production of omethoate, methamidophos, paraquat and glycyrrhizinic phosphor, etc., which made a stable foundation for INSIGHT's development. We had also achieved great success in the high efficiency low toxic pesticides, such as imidacloprid, etofenprox, metalaxyl and in the new synthetic methods in various amino acids as well as in the pharmaceutical intermediates. The new method of preparation indigo using N-phenylglycinonitrile is an advanced process in the world in terms of the clean production technology for Ferro cyanide and HCN's transformation rate improvement. We solved the pollution problem of the old route. The newly developed substituted product for indigo using a clean production technology which greatly reduced the material consumption and environmental pollution. Insight has facilities producing nearly 20 photo-initiators and developed the new technique for light-curing lubricity, water-born resin, the technique for water-bon coating and their associated applications. The successfully developed technology of new high performance emulsion will promote the technology advancement in the coating industry and the wide spread of new coating in China.Insight has developed a series of new technologies, including a novel reactor technology - using a newly designed patented blade, has been characterized as high efficiency & energy saving reactor.The novel technology research and development are widely applied in INSIGHT's ten-year practice.We studied and confirmed the non-thermal catalyzing effect of microwaves, proposed a "weak microwave" theory, and a chemical reaction rate equation. We proposed that in the existence of microwave magnesium ions and phosphate, amino acid can be activated to form peptide which maybe the path of the origin of life.A 3000mt/a pilot plant in Chongqing using carbon monoxide and hydrogen to produce dimethyl ether in a single step has been built via collaboration with the Dept. of Chemical Engineering at Tsinghua University. The large scale, low cost production of dimethyl ether may possible through comprehensive technology improvement. This technology will take full advantage of current ammonia production facilities, and try to solve the global fuel shortage problem. 相似文献
