在高校课程教学改革中,随着信息技术的发展,混合学习模式的研究成为新的研究方向。实施混合教学有助于改善医药类专业无机化学实验教学现状。以医学院校无机化学实验教学为例,以混合学习为导向,构建了实验混合学习教学模式。教学形式包括微课、PBL、仿真实验、实验考核等,传播方式包括Blackboard平台和QQ群信息平台。通过课堂教学和课下在线自主学习方式进行教学,可以培养学生自主创新和动手能力,提高教学质量。 相似文献

化学实验是化学科学的基础,化学教学向来都十分重视化学实验的教学,本轮教育改革更是专门设置了实验化学模块,是唯一独立设置的实验课程。实验课程是对传统化学实验教学观念和方式的洗礼。下面仅以新课标《实验化学》教材实验3.1为例来谈谈如何搞好实验教学。按照教材要求,提供含有 Fe~(3+)、Al~(3+)、Ag~+、Ba~(2+)中三种或 相似文献

农学专业作物生产类实验课程群建设的探索 总被引：1，自引：0，他引：1
针对农学专业作物生产类课程实验内容重复、实验类型比例不当,教学效果不好等一系列问题。以课程群建设的思路,提出以编写作物生产类实验课程群配套教材建设为突破口,打破传统以实验论实验,以课程为单元的教学运行机制,形成与理论教学体系相对独立的实验课程群,为提升学生综合能力的实验教学运行模式奠定基础。 相似文献

关于高师院校化学专业实验课程体系改革的思考 总被引：1，自引：1，他引：1
推进高师院校化学专业实验课程体系的改革,打破"四大化学"的界线,以实验基本操作技术为主线,在4年中分别开设化学实验基本技术、化学中级实验技术、综合性实验和设计性实验4门课程,使实验课程教学具有独立的课程体系,既体现了实验教学和理论教学的等同地位,也强化了综合性、设计性实验的开设过程,充分发挥了实验教学对学生综合实验能力、创新意识的培养功能. 相似文献

汉字的六书,《说文》对“转注”一类,语焉不详。后世学者提及转注,也仅限于许慎所举出的例字。《汉字例说》一文,作者从转注的角度综合考虑,对部分现代常用字作了分析,跟传统的解释有所不同。希望能抛砖引玉,互相切磋,以推进学术研究。 相似文献

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love. 相似文献

The problem on the geometrc inequalities involving an n-dimensional simplex and its inscribed simplex is studied. Aninequality is established, which reveals that the difference between the squared circumradius of the n-dimensional simplex andthe squared distance between its circumcenter and barycenter times the squared circumradius of its inscribed simplex is not lessthan the 2(n-1)th power of n times its squared inradius, and is equal to when the simplex is regular and its inscribed siplex is atangent point one. Deduction from this inequality reaches a generalization of n-dimensional Euler inequality indicating that thecircumradius of the simplex is not less than the n-fold inradius. Another inequality is derived to present the relationship betweenthe circumradius of the n-dimensional simplex and the circumradius and inradius of its pedal simplex. 相似文献

Migration occurs behind a variety of reasons and has a great effect on the whole world. People may migrate in order to improve their economic situation, or in order to escape civil strife, persecution, and environmental disasters. The impact of migration is complex, bringing both benefits anddisadvantages. This paper briefly talks about the causes of migration, the allocation of benefits, and the ways in which individual countries and the international community deal with this important subject. 相似文献

Using virtual reality for interactive design gives a designer an intuitive vision of a design and allows the designer to achieve a viable, optimal solution in a timely manner. The article discusses the process of making the Virtual Reality System of the Humble Administrator＇s Garden. Translating building data to the Virtual Reality Modeling Language （VRML） is by far unsatisfactory. This creates a challenge for computer designers to do optimization to meet requirements. Five different approaches to optimize models have been presented in this paper. The other methods are to optimize VRML and to reduce the file size. This is done by keeping polygon counts to a minimum and by applying such techniques as object culling and level-ofdetail switching. 相似文献

The awareness of individualism can be traced back to the period of American Revolution when the Declaration of Independence was produced.It expressed basic beliefs concerning freedom,equality,democracy,privacy and the relationship between people and government,which were exactly what the philosophy of individualism mostly dealt with at that time.This paper is to exploit the essence of individualism by analyzing the Declaration .The analysis enables us to reconsider its significance to the issue of America human rights and foreign policies. 相似文献

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities. 相似文献
