谈有机化学实验中的开放实验模式 总被引:12,自引:0,他引:12
化学是一门以实验为手段 ,以应用性、创造性为特征的学科 ,因此化学实验是大学化学教学中极其重要的一部分 ,也是培养学生创新意识、创新能力的重要途径。但是原有的实验教学模式存在许多缺点与不足 ,培养的学生越来越不适应社会的要求 ,突出表现在以下几方面 : (1 )原有的实验教学体系采用的是单一验证式知识型的教学模式。大部分化学实验是起验证作用 ,学生学习兴趣低 ,对所面对的实验只是粗略了解 ,无法深刻地理解实验的设计思想。学生的观察能力弱 ,从观察事物现象中获得的东西甚少 ,久而久之对观察不感兴趣 ,缺乏应有的求知欲。 … 相似文献

Natural product chemistry experiments, which train the students to master the basic skills for extraction, separation and identification of the active components of natural products, and acquaint with the research methods of natural product chemistry, are an important part of organic chemistry laboratory. This paper analyzes the common problems related to the current natural products chemistry laboratories in domestic universities. In recent years, we carried out the reforms of the teaching contents, teaching conditions, and teaching methods. The teaching practices show that the students' learning interest and efficiency, the abilities to analyze and solve problems, and the scientific research abilities have been trained and strengthened. The teachers' experimental teaching level and teaching quality have been greatly improved. 相似文献

The ability of scientific inquiry is one of the important abilities of undergraduate students. We have been thinking and exploring to cultivate students' scientific research ability in the course of laboratory teaching. In recent years, we had carried out persistently reform and practice to the laboratory teaching content and the teaching method in organic chemistry, for example, introduction to the frontier of scientific research, exploring the abnormal phenomena of the experiment, organization of experiment discussion, and carrying out the extracurricular research experiments. The above measures can greatly stimulate the students' interest in learning. Their abilities to think, observe, analyze and solve problems were fully developed. The students' ability of scientific inquiry had been cultivated in multiple aspects. The above measures have effectively promoted the improvement of teaching quality of organic chemistry laboratory course, and also supported the training objectives of high-quality innovative talents in chemistry. 相似文献
