物理概念和物理规律是人们通过对大量实验、客观实体等进行高度抽象和概括的基础上而形成的,它反映了事物的本质和事物之间变化发展的必然规律.如何在教学中把抽象的概念和规律具体化、形象化一直是物理教育研究的重要课题.本人结合多年教学经验概括总结出以下几点心得. 相似文献

In view of the complex knowledge points and some abstract theories of pharmaceutical chemistry courses, the application of visualized teaching methods to present important knowledge points in a vivid way can enhance the teaching effect and stimulate students' interest in learning. Based on the authors' teaching and research work, this article summarizes the application of figurative teaching methods such as metaphor and analogy in inorganic chemistry and medicinal chemistry courses. 相似文献

A reliable validation based on the optical flow visualization for numerical simulations of complex flowfields is addressed
in this paper. Several test cases, including two-dimensional, axisymmetric and three-dimensional flowfields, were presented
to demonstrate the effectiveness of the validation and gain credibility of numerical solutions of complex flowfields. In the
validation, images of these flowfields were constructed from numerical results based on the principle of the optical flow
visualization, and compared directly with experimental interferograms. Because both experimental and numerical results are
of identical physical representation, the agreement between them can be evaluated effectively by examining flow structures
as well as checking discrepancies in density. The study shows that the reliable validation can be achieved by using the direct
comparison between numerical and experiment results without any loss of accuracy in either of them. 相似文献

"形象化教学"在光学课中的尝试 总被引:1,自引:0,他引:1
“光学”是一门重要的物理基础课.为改善学生的学习效果,加深学生对光学理论的掌握,我们在教学工作中尝试了一种新的教学方法——“形象化教学”.通过使用幻灯片、计算机仿真和光学演示实验等手段,提高学生对光学的学习兴趣,并加强学生对光学理论知识的形象化理解,提高学生对光学知识的利用能力。 相似文献
