Study on the design and analysis methods of orthogonal experiment
Liu Ruijiang,Zhang Yewang,Wen Chongwei,Tang Jian(School of Pharmaceutics,Jiangsu University,Zhenjiang 212013,China)The importance of orthogonal experimental design and analysis is introduced briefly.The principle and characteristic are expounded.The design methods of orthogonal experiment and analysis methods of orthogonal experimental results are analyzed in detail,which afford fully systemic methods for orthogonal experimental design and analysis.Problems in orthogonal experimental design and analysis and development of software for orthogonal experimental design and analysis are also pointed out in the end.
Research on statistical analyses and countermeasures of 100 laboratory accidents
Li Zhihong;Training Department,Kunming Fire Command School;This paper summarizes 100typical cases of laboratory accidents from 2001and analyzes the cases in fields of accident type,accident link,accident cause,dangerous substance category,etc.The result shows as follows:the fire disasters and explosive accidents are the main types of laboratory accidents;the dangerous chemicals,instruments and equipment,and pressure vessels are main dangerous substances;the instruments and equipment and reagent application processes are the main links of accidents;the violation of rules,improper operation,carelessness,wire short circuit and aging are the main reasons of accidents.It also puts forward the countermeasures and suggestions for the prevention and control of laboratory accidents in the following aspects:establishing complete safety management system,actively promoting standard construction of laboratory safety,strengthening laboratory safety education and training,and formulating and improving emergency plans for laboratory accidents.
Promotion of reform and innovation on integration of theory teaching and experimental teaching by virtual simulation experiment teaching
XIONG Hongqi;Based on the concept of experimental teaching and its importance, the connotation of virtual simulation experimental teaching is expounded upon. On this basis, this paper puts forward six balance principles that virtual simulation experimental teaching should follow to promote the upgrading and reconstruction of traditional experimental teaching and elaborates the reform idea of virtual simulation experiment teaching for the overall optimization and innovation of theory teaching. The brief analysis is carried out on that the introduction of virtual simulation experimental teaching is conducive to promoting innovation and entrepreneurship education into the whole process of professional education.
The application of studying fluorescence spectroscopy on protein
Yin Yanxia,Xiang Benqiong,Tong Li(College of Life Science,Beijing Normal University,Beijing 100875,China)Fluorescence spectroscopy is very important for studying protein structure and conformation changes.The concept and principle of fluorescence spectroscopy are introduced at first,then the application of studying fluorescence spectroscopy on protein is explained.
Research and application of BOPPPS teaching method in MOOC teaching design
WU Changdong;JIANG Hua;CHEN Yongqiang;School of Electrical Engineering and Electronic Information,Xihua University;School of Information Science and Technology,Southwest Jiaotong University;On the basis of introducing the connotation of BOPPPS(bridge-in,objective,pre-assessment,participatory learning,post-assessment and summary)model,this paper explores upon the guiding role of the BOPPPS teaching model in MOOC teaching design.Based on the BOPPPS model,MOOC teaching design of"Series feedback voltage stabilization circuit"is carried out.This provides some reference for improving the quality of MOOC teaching design,stimulating students' learning interest and motivation,and promoting teachers' reform of teaching content design.
Constructing practice teaching system focusing on ability training
Zhang Zhongfu(Zengcheng College,South China Normal University,Guangzhou 511363,China)The economic and social development has given rise to an increasing demand for applied talents,and people have attached more and more importance to practice teaching.The practice teaching system should focus on ability training,build practice teaching system,adjust the practice teaching contents,reform practicing teaching pattern,coordinate practicing teaching administrating system,and constructing a scientific and reasonable quality ensuring system and a practicing teaching evaluation system.
Safety education being the key to keep the laboratories safe in universities
ZHAO Qing-shuang,LI Ming,WEN Xing-huo(Office of Laboratories and Facilities,Tsinghua University,Beijing 100084,China)Safety education is one of the most important contents in safety management.It is the key measure of keeping the laboratories safe in universities.The significance of strengthening laboratory safety education for undergraduates and graduates was discussed.The function of safety education was expound.The methods of valid safety education were put forward,and the practice and effect of safety education were summarized recently in Tsinghua Univer-sity.
Exploration on construction idea and development mode of virtual simulation experimental teaching center
Liu Yafeng;Yu Longjiang;College of Life Science and Technology,Huazhong University of Science and Technology;The virtual simulation experimental teaching center is an important platform to cultivate students' ability of innovation and practice.Its careful planning will affect the teaching effect and the sustainable development.The practical teaching system with the combination of virtual and real experiments is suggested.The real teaching experiments should be the primary teaching mode and the virtual one is its important supplementary.These ideas will promote the rapid and orderly construction and development of virtual simulation experimental center.
Study on innovative ability cultivation mode of undergraduates based on subject competition
Li Guofeng,Zhang Shiying,Li Bin (Educational Administration Deptartment Changsha University,Changsha 410003,China)Subject competition is correlative with the innovative ability for the undergraduates.The innovative ability cultivation mode for undergraduates based on subject competition is the "Trinity" mode with the foundation of curriculum teaching,the carrier of competition items and the means of technical training.To establish the innovative ability cultivation mode for undergraduates based on subject competition,following some of principles is very necessary.The teaching and training plan must be made accordingly,and the operation security system,the incentive system,performance evaluation system and quality feedback system for this mode should be establised.Obvious effect has been obtained by using this mode to cultivate undergraduates' practical ability and innovative ability.
