无机及分析化学实验是汉江师范学院生物科学专业在大一开设的首门必修实验课程,其教学质量对后续专业课程的学习、学生学术研究能力和创新性思维的培养等具有重要意义。然而,汉江师范学院无机及分析化学实验教学过程中存在理论课程与实验课程教学进度不匹配、学生课前预习不充分以及课程期末考核方式单一等问题。笔者通过课件推送、问题收集、能力提升的“三维”教学模式,突出学生的主体地位,将实验课程的考核机制落实到课程学习的各个环节,旨在提高学生的学习动力和激发学生的求知欲。该“三维”教学模式的实施对提高无机及分析化学实验课程的教学质量具有重要意义。 相似文献

分析化学实验是一门兼具理论性、实践性和应用性的课程,主要训练学生规范操作并培养学生运用分析化学理论知识解决实际问题的能力。目前普遍存在着分析化学实验课程教学与理论教学严重脱节的问题,学生习惯“照方抓药”。本文将问题导向学习法应用于分析化学实验教学,通过改进教学模式、完善课程内容和优化考核方式开展教学改革,促进实验与理论教学的有效融合,充分调动学生的学习自主性,培养学生观察、思考、分析和解决问题的能力,有效提高实验课的教学效果。 相似文献

Stimulated by the rapid growth of analytical chemistry in research and development, a discussion on the past, present and future role of analytical chemistry as part of the chemistry curricula at European universities is presented in this article. The present status of analytical chemistry curricula is described, based on a recent investigation of the Working Party on Analytical Chemistry (WPAC) of the Federation of European Chemical Societies (FECS) at 229 European universities. The evaluation of the questionnaires has been done for all institutions together, as well as for the 119 institutions with a separate chair or department of analytical chemistry and the 110 institutions without such a separate chair. The distribution of teaching hours between the classical and modern fields is generally significantly better and more flexible to new developments (like chemometrics, environmental and material sciences) at institutions with an own chair of analytical chemistry. This survey is also a key to earlier reviews on education in analytical chemistry stimulated and published by WPAC-members. 相似文献

通过对目前分析化学教学中存在问题的分析,探究了新工科背景下分析化学专业中关于质量保证和质量控制方面的教学改革,提出了增设“分析化学中的质量保证和质量控制”或者类似的课程的建议,指出分析化学的教学应该围绕整个分析过程展开,并将分析化学中的质量保证和质量控制知识融入分析全过程中,注重理论课程与实践课程相互结合的同时更加强调应用性,增强学生的实践能力和分析问题、解决问题的能力。此外,分析化学教学重在“分析”,要与分析实验室/检测机构保持紧密联系,应建立以市场为导向、以技术为核心的教学活动,从而实现为社会不断培养与时俱进的分析人才的教育目标。 相似文献

Summary Analytical chemistry is a discipline which has a large impact in other fields of chemistry and natural sciences as well as in technology and society. Traditionally, analytical chemistry has been grouped together with inorganic chemistry to such an extent that they are often viewed as a single discipline. While this has been beneficial for the development of both inorganic and analytical chemistry, it is increasingly important that the need of analytical education by the organic and biochemists as well as by chemical engineers is clearly recognized. The tightening environmental protection requires the analyst to be conversant with more sensitive, more accurate, and more reliable techniques in novel chemical surroundings, but at the same time he has to have as thorough knowledge in every field of chemistry as possible. 相似文献

简述了分析化学的发展历史。分析化学的"昨天",从基于物理化学的溶液理论,以目视可见为工具的"化学分析",进入以物理方法为基础的仪器分析,因此有人提出"化学正在走出分析化学";分析化学的"今天",因为它的主体任务是解决物质的分子原子结构和成分,所以又回归化学领域;对分析化学的"明天"寄厚望,分析化学走出历来仅仅以"为他人报告提供数据"的技术支持者的角色,成为"实际问题解决者",利用分析化学中综合分析的"剖析技术",为新产品开发创制的"反工艺研究"做出独特的贡献。 相似文献

Analytical chemistry is consolidating an important position within the framework of our modern industrial community; the frontiers of trace (and ultra-trace) analysis have expanded into new territories, thus demanding a constant change in our mode of thinking in a substance-related manner in analytical chemistry. An outline of the development of analytical chemistry during this century reveals a period of underdeveloped research and education followed by a current phase of impetuous advancement. However, as a result of increasingly antagonistic sectional convictions in the public mind concerning reservations against, as well as efforts towards, efficient technological progress, this advancement evokes new existential risks for analytical chemistry—viz. either to be used in an uncritical way or to fall into discredit following slogans like ‘high-performance analytical chemistry is to blame for it all!’ A much more constructive consideration says that risks can be estimated and evaluated solely by means of a highly efficient analytical chemistry, when used with a sense of responsibility. Analysts may help to clarify and to cope with the increasing fear of decreasingly smaller amounts of trace elements—in both adverse groups in our community. Strategies necessary to gain this end are outlined with regard to a methodological as well as a political platform. 相似文献

Several important aspects are considered: the definition of analytical chemistry, the intercorrelation of this field and other sciences, the content of the theory of the discipline, and the internal structure of analytical chemistry. Attention is paid to the incentive for the development of analytical chemistry as a science. The ratio of basic and applied aspects is discussed. Finally the name of this branch of science is considered. 相似文献

作者首先叙述了分析化学的源起,认为这门科学与人类文明文化,如青铜、黄铜冶炼、酿酒等大有关系。继出现东、西方的丹金术、欧洲中世纪的大试金术。后者可称为现代分析化学的前驱。适十七八世纪现代化学之兴起,分析化学起了主要作用。嗣后重量法、容量法、比色法、分光光度法、发射光谱法、极谱法、质谱法、层析法等等相继出现。这些方法可分为两大类——即化学法和仪器法。二者各有其优缺点;需要相辅相成,而决不是对立、排挤。另一方面,常量法之后又出现微量法和痕量分析。最后为分析化学在我国健康成长提出一些看法和意见。 相似文献
