中学化学教学中渗透环保教育的实践与探讨

环境问题已成为当今社会四大危机之一,引起了世界范围的广泛关注。而化学与环境问题有着密切的联系。本文结合多年的教学实践,从课堂和非课堂两个层面,对如何利用初中化学教学平台来帮助学生提高环保意识进行了探讨。     

新课程背景下学生问题意识的培养

问题意识的淡薄是制约学生创新思维发展的重要因素.论述了新课程背景下学生的问题意识及其重要性,制约学生问题意识的重要因素,研究和探索如何培养学生＂问题意识＂的方式和方法,并为培养学生＂问题意识＂的教学研究提出见解和实施策略.     

高一化学教学策略初探

高一化学教学在高中化学教学中起着承上启下作用,是整个高中化学教学的关键。为使学生在高一打下坚实的基础,在教学中,培养学生学习化学的兴趣,认真贯彻“教师主导、学生主体”,及时解决学生学习中的盲点,并重视科学方法的训练。     

固相化学反应的热力学分析及其优势探讨

从热力学角度分析了固相反应的吉布斯自由能变,印证了固相反应一旦发生,便能进行到底的结论.并且,探讨了固相反应在化学合成和保护环境等方面较液相反应具有非常明显的优势.     

PBL 教学模式在中药化学教学改革中的实践与探 讨简

通过对目前中药化学课程教学情况的分析,结合我院自身特点,将PBL教学模式与传统教学方法有机结合,开展中药化学教学改革实践活动,旨在加强学生素质教育,提高教学质量,强化实践应用型中药学人才的培养质量．     

在化学实验探究中培养学生创新能力

在化学实验中通过教师演示实验、学生设计实验、学生探究实验等途径培养学生的创新能力和创新意识,进而提高学生化学实验的积极性和主动性。     

开设设计性化学实验的探索与实践

在无机化学实验课上开设了设计性实验.通过四个教学环节,不但提高了学生独立设计实验、独立进行实验的能力,而且还培养了学生的创新精神.     

The effects of science,technology, society and environment （STSE） education on students＇ career planning

The leakages in secondary level education brought forward the necessity to restructure the educational system so as to address the social and individual needs and meet the requirements of Turkey; therefore, a ＂reformation＂ study became an obligation. The formal education in Turkey starts at the age of 6, when the individual is shaped within the system. Determination of the characteristics of an ideal future citizen of a country should be apprehended at all levels of education and individuals should attain these appreciated characteristics. The reformed science education programs in Turkey aim to guide the individuals to be scientifically and technologically literate. Through enabling an individual, who is in a technological media, to attain the required knowledge, skills and attitudes, the individual should have the ＂science and technology literacy and creative thinking＂ skills. Individuals should recognize the technological environment they live in as well as the dimensions and facilities of technology, and should be aware of the fact that they could make use of these opportunities. In the light of this aim, this study involves the teaching of ＂separating mixtures＂ to 9th grade students in relation with science, technology, society and environment and the examination of its possible effects on students＇ achievement as well as their career choices. The Chemistry Achievement Test and the Career Choice Questionnaire were administered as pre- and post-test to serve as data collection tools. The study concluded that chemistry education in relation with science, technology, society and environment would lead students to choosing different fields for their future careers by changing their perspectives towards science. A significant increase in students＇ chemistry achievement levels was also observed.     

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。     

中西医结合治疗粘连性肠梗阻临床观察

观察中西医结合治疗粘连性肠梗阻的临床疗效。将127例粘连性肠梗阻病人随机分成二组:对照组采用单纯西医治疗;治疗组在西医治疗的基础上加用加味承气汤胃管注入及保留灌肠,同时配合针灸治疗。结果,治疗组治愈率明显优于对照组,两组比较有显著性差异(P<0.05)。结果表明,中西医结合治疗粘连性肠梗阻可显著提高疗效,值得推广。
