关键词： 化工专业   分析化学   实验   教学改革  

摘要： 分析化学实验是研究物质的组成、含量、结构和形态的分析方法及理论的一门科学,是化工专业一门重要的课程。现有的分析化学实验课程的项目设置比较突出基础理论,教学模式比较陈旧,没有突出化工专业特色,培养学生的教学效果不够理想,难以适应新时期企业对化工人才的需要。因此有必要进行分析化学实验的教学改革。本课程的教学改革主要分为5个方面,包括设置专业特色的实验、专业教师辅助实验教师授课、双语教学、使用英文实验教材以及使用新的教学模式。

摘要： Over the last several decades, science has benefited tremendously by the implementation of digital electronic components for analytical instrumentation. A pioneer in this area of scientific inquiry was Howard Malmstadt. Frequently, such revolutions in scientific history can be viewed as a series of discoveries without a great deal of attention as to how mentorship shapes the careers and methodologies of those who made great strides forward for science. This paper focuses on the verifiable relationships of those who are connected through the academic tree of Malmstadt and how their experiences and the context of world events influenced their scientific pursuits. Particular attention is dedicated to the development of American chemistry departments and the critical role played by many of the individuals in the tree in this process.

摘要： GEOKhI was the initiator of the LunaGlob and PhobosGrunt projects (Galimov et al., 1998). The main objectives of the LunaGlob project were exploration of the Moons interior structure and searching evidence for the presence of water in the lunar polar craters. The main objective of the PhobosGrunt project was the return of soil samples from the surface of Phobos (Fig.1). GEOKhI proposed a proprietary analytical scheme for studying soil samples, which became the basis for the project and involved isotopic, geochemical and mineralogical analyses. The three-oxygen isotope data (16 1718) from this study could be used to clarify whether Phobos is captured or formed in situ. The study of organic compounds from Phobos was essential for the evaluation of the probability of the origin of life on Mars. The proposed analytical scheme involved isotopic, geochemical and mineralogical analyses. Work on these projects began in 1997. If these projects had been implemented, Russia would have recaptured global leadership in space research. This however did not happen (Galimov, 2015). I will not go into details about many interesting solutions that have been developed under these projects over almost 20 years, yet I will give a brief sketch of the scientific payload mounted on the PhobosGrunt spacecraft, which failed to complete its mission in 2011.

关键词： Interdisciplinary character   Method validation   Graduate education   Curricular implications  

摘要： Students not familiar with chemistry tend to misinterpret analytical chemistry as some kind of the sorcery where analytical chemists working as modern wizards handle magical black boxes able to provide fascinating results. However, this approach is evidently improper and misleading. Therefore, the position of modern analytical chemistry among sciences and in the contemporary world is discussed. Its interdisciplinary character and the necessity of the collaboration between analytical chemists and other experts in order to effectively solve the actual problems of the human society and the environment are emphasized. The importance of the analytical method validation in order to obtain the accurate and precise results is highlighted. The invalid results are not only useless;they can often be even fatal (e.g., in clinical laboratories). The curriculum of analytical chemistry at schools and universities is discussed. It is referred to be much broader than traditional equilibrium chemistry coupled with a simple description of individual analytical methods. Actually, the schooling of analytical chemistry should closely connect theory and practice.

摘要： 目的探索以团队为基础的学习(TBL)教学法在药学专业分析化学仪器分析部分的教学成效。方法将TBL教学法引入药学专业分析化学课程中高效液相色谱法(HPLC)原理一节的教学,在本校药学系2015级三年制药学专业专科生中根据年龄、成绩等采用区组随机化分组法随机选取1班(研究组)和2班(对照组)学生70名,每组35名。研究组采取TBL教学法,对照组采取传统讲授法。比较两组学生学习成绩、研究组学生对TBL教学法喜欢的程度和2种教学法的优缺点。并进行统计比较。结果研究组学生学习成绩[(80.08±5.64)分]明显高于对照组[(68.47±5.69)分],差异有统计学意义(t=3.376,P<0.05)。且TBL教学法能有效提高学生自主学习能力、提高独立分析问题和解决问题能力、提高团队协作及人际沟通能力等。结论在分析化学仪器分析部分教学中采用TBL教学法有助于提高学生学习成绩、培养学生多种能力,具有可行性。
