按照时间脉络将我国中学化学实验教学发展历程划分为4个主要阶段。第1个阶段是借鉴前苏联、摸索前进期,伴随着新中国的诞生,我国新的教育体系逐步建立。从教育部颁布的第1部《大纲》起,中学化学实验教学的地位就被确立下来并一直延续至今。这一历史时期的中学化学实验教学对学生掌握“双基”发挥了比较重要的作用。第2个阶段是遭遇“文革”、破坏倒退期,中学化学实验教学受到多次“运动”的冲击,一度停滞。 相似文献

合班授课教学模式下最大的问题在于难以兼顾各专业实施教学,导致难以激发学员的学习兴趣,定制与专业相关的教学案例恰好能够解决上述问题。本文精选骨质疏松症及新生儿黄疸这两个医学案例,重点探讨了如何贴近护理和生物医学工程专业的需求,定制化设计这两个医学案例,并在医学化学绪论课中实施;实施后通过平时的访谈和期末考试医学应用题的得分统计情况发现,这种定制化的案例教学能够从本质上激发学员的学习热情,也能达到合班教学中兼顾各专业的目的。 相似文献

In this paper, 15 years of the experiences acquired concerning the teaching of chemical metrology in Latin America are presented.
These include postgraduate and undergraduate activities developed in eight countries. The combination of theoretic and practical
activities and the sequence of learning from metrological, statistical, and chemometrical backgrounds up to practical activities
in personal computers are basic and motivate the learning process. Care is taken to promote the metrological approach and
thinking in analytical chemistry. The learning of computing techniques plays an important role, combining graphic and numerical
techniques for data analysis. The role of examples during the teaching process is analyzed and recognized. The introduction
of a general model of errors permits one to approach different topics on a metrological basis. The metrological approach of
uncertainty based on the theory of errors permits one to develop the topic. Undergraduate students acquire a basic metrological
knowledge and other experiences are also presented. Recommendations for undergraduate and postgraduate programs are pointed
out. 相似文献

The imbalance between teaching and learning, because of individual difference and the simplicity of teaching, can lead to interest losing on study, which will hinder the further learning. Here, based on the course content, certain scientific software are introduced in chemical laboratory lesson before and after class, thus, students can understand the experimental phenomena with the assistant of this teaching approach. Then laboratory lesson is connected with theory lessons to demonstrate the compounds they synthesized during experiment through a scientific software. The design helps the students understand the role of the software in judging and solving scientific issues. At last, the teaching practice is summarized and reconsidered to point out the essentials in the designing process. 相似文献
