为解决当前地方工科院校大学物理课程教学存在学生自主学习能力不强、缺乏物理学研究方法的教学内容、忽视过程性评价等普遍性和特殊性问题,此课程应基于"学生中心、产出导向、持续改进"的教育理念,围绕立德树人根本任务,从教学内容、过程方法和评价方式等方面进行多元化教学设计,重构"五结合四贯通两衔接"的教学内容,打造"三阶六环"督学、促学、导学模式,采用共性与个性相结合的多元化评价体系.这样,课堂气氛得到了激活,学生学习兴趣、思辨能力、学习成绩得到了有效提升,取得了令人满意的教学效果.

基于大学物理课程实行模块化教学的思考,将该课程分为基础模块和专业模块,基础模块包含大学物理课程中需要学生掌握的基本理论和基本知识的五个教学模块.专业模块是根据不同专业后续课程的需要所设置的模块.通过模块构建,既满足不同专业学生的需求,同时一定程度上实现教学内容的优化,还能很好激发学生学习的兴趣.

Fe3 O4 nanoparticles were prepared by co-precipitation and combustion method .X-ray diffraction instrument ,scanning electron microscopy ,transmission electron microscopy ,UV visible spectroscopy and vibrating sample magnetometer were used to study the physical properties of Fe 3 O4 nanopartides .The results show that Fe3 O4 has single magnetite mineral phases ,homogeneous distuibuted sizes ,and superaramagnetism .Under the normal temperature ,the saturation magnetization of Fe3 O4 nanoparticles is as high as 63 .5 emu/g .

This paper shows the problems of "Theoretical Mechanics" course survey, and then explores how to improve the teaching quality by using the diversified teaching-model.

This paper shows the numerical calculation and simulation of "mathematical physics equation" based on MATLAB software,then to improve the visual teaching through the physical meaning of equations by analyzing the resulting image.

从大学物理教学现状出发,把MATLAB应用到大学物理教学中,从而提高大学物理教学质量。

本文利用MATLAB软件对《电磁学》中经典实例模型进行可视化仿真，使得物理求解与物理模型得以清晰直观的呈现，从而提高电磁学教学质量。

From the emotional point of view, speech expressive lable has been studied , and the paper proposed a new speech expressive lable scale. Experiments show that, the speech expressive lable scale save time, the results could better reflect the expressiveness of speech, and consistency of test results have improved significantly.

Distribution of complex amplitudes of circular aperture and barrier sphere diffraction imaging is deduced by Fresnel diffraction theory.And imaging formula accordance with results of half-wave and vector method is obtained by their distribution of complex amplitudes.And the different of phenomenon of circular aperture and barrier sphere diffraction imaging is theoretically studied and Poisson's spot of causes is analyzed.So the method could help ones to understand diffraction imaging's process.

In this paper,the Generalized Dynamic Model of Low-Energy QCD was derived from the Spin-charge Separation Model and the Generalized Model which was introduced by Faddeev and Niemi in 2004,then we discussed the relation between the dynamic model and the Faddeev-Niemi model.
