Mobile APP for motivation to learning: an engineering case

Synthesis of Materials is regarded as an important core subject in engineering education. However, many concepts and knowledge in the material synthesis can be rather abstract and difficult to understand by the student learners. Experiments are limited in scope due to lack of equipment, control of toxic materials, and risks of chemical reactions, which often restricts student imagination and student involvement in practical training. These reasons often led to poor learning attitude and learning performance among the students. Rapid developments in Cloud technology and mobile devices have provided new opportunities for developing novel learning tools for material synthesis. This study aims to introduce interest factors as a strategy for promoting learning interest and practical skills among the students. Chemical symbols, experimental themes, texts, and interactive elements were utilized to develop a theme-based Mobile Learning APP for teaching the practical techniques of material synthesis. The Mobile Learning APP was then integrated into a problem-based learning activity. A quasi-experimental design was used to investigate the resulting learning effectiveness from using the developed Mobile Learning APP. Results show that the Mobile Learning APP provided a significant positive effect on learning performance and that most students showed favorable attitudes toward the usage of the mobile learning system.     

发展旅游循环经济的制度建设研究

旅游循环经济作为一种崭新的实施旅游可持续发展战略的最佳经济发展模式已经被世界各国普遍接受和重视。我国旅游业的快速增长给环境、经济、社会带来了不少问题，影响了旅游业可持续发展的顺利开展。我们应根据中国具体国情，积极借鉴和汲取国外的先进经验，构建和完善具有中国特色的旅游循环经济制度体系，包括政策机制体系、法律法规体系、科技研发体系、社会宣传体系等，使旅游循环经济法制化、社会化。     

高师院校代数与几何课程改革的探索与实践

随着高师院校课程与教学改革的不断深入,代数与几何合并设课已成为高师院校课程与教学改革的选择方案之一.将两门课程整合起来合并设课,不仅能够体现高等代数作为解析几何的工具作用,而且能极大地丰富高等代数的几何背景和几何解释,关注代数思维,突出几何直观.

论人民币汇率制度与汇率机制

人民币汇率问题的焦点是人民币的合理估价,而人民币合理估价的形成取决于我国的汇率制度及相应机制。各国汇率制度的选择是基于国情以及经济发展的需要,中国人民币汇率制度的形成正是中国特色的市场经济发展的必然结果。理论和现实已证明中国的人民币汇率制度是符合中国国情、科学合理的,只是随着国际、国内形式的变化和体制改革的深化,其实现形式人民币汇率机制,渐露不足,需要调整。因此,在保持汇率基本稳定的前提下,改革和完善人民币汇率机制是解决人民币汇率问题的根本途径。     

Educational Assessment in China: Lessons from history and future prospects

Imperial China is widely regarded as having introduced the first systematic assessment system for civil service appointments. This paper briefly reviews this history and then discusses the evolution of assessment during the twentieth century, especially the period of the People's Republic from 1949. It explores the highly centralised nature of the resulting system, which changed as political and economic circumstances dictated.
