Students learning may be classified according to the sensory modalities using VARK instrument, which categorizes learning modes as visual (V), auditory (A), reading-writing (R), or kinesthetic (K). We administered the VARK questionnaire to our second-year medical students, and 98 of 133 students (74%) returned the completed questionnaire. Only 14.3% of the students preferred a single mode of information presentation. In contrast, most students (85.7%) preferred multiple modes of information presentation. Knowing the students preferred modes and using web-based learning system may help the instructors to tailor to the student's individual preference in the teaching of medical science.

During the operation of heated oil transportation pipeline, the shutdown is caused by some pipeline accidents or repairing. In order to ensure the safety operation of the pipeline, determine the temperature drop and restart pressure needed at different shutdown lasting time is important. This paper builds the heated oil pipeline shutdown and restart mathematic model based on heat transfer and fluid mechanics theory. The VB and MATLAB hybrid programming method which is on the basis of COM technical is utilized to develop heated oil pipeline shutdown and restart simulation software. The software application shows using of VB and MATLAB hybrid programming method can reduce the work of algorithm developing and enhance the reliability of heated oil pipeline shutdown and restart simulation software.

GML is the encoding specification of geospatial data, currently more and more geospatial data are represented in GML documents. In order to query GML data efficiently, appropriate index structure should be designed. As the application of XML in geospatial information field, the management of GML data can borrow ideas from the management technologies of XML data. Two types of existing XML path index technologies are analyzed, and a method to build path index for the GML document is proposed based on its storage schema. The path index records the sequences and levels of elements in the GML document. Tuples stored in tables can be quickly located for a query with the path index, and the structure information recorded in the path index can help to reconstruct the GML document.

In this paper, we present an improved particle swarm optimization (PSO) algorithm to solve constrained optimization problems. The proposed approach, called MPSO, employs a novel mutation operator to enhance the global search ability of PSO. In order to deal with constrains, MPSO uses mean violations mechanism and boundaries search. Simulation results on five famous benchmark problems show that MPSO achieves better results than standard PSO and another variant of PSO.

It is an inevitable choice for college and universities to foster an innovation talent through guiding students to conduct research-learning. In order to foster a “student-oriented” concept and try to bring up the students’ research capabilities in our whole process of teaching, teachers should improve their own teaching abilities and academic levels, carry out research-teaching actively, and make it align with students’ research-learning. It develops research quality and trains students to form an awareness of research so that teachers can promote research-learning in teaching of the basic theoretical courses. This article describes the effectiveness of pilot projects and pilot cases.

Undergraduate Tutorial System in University of Oxford can provide useful enlightenment for undergraduate teaching reform in the agricultural and forestry universities in China. As a new undergraduate training mechanism, we have found serious problems in implementation of Undergraduate Tutorial System, such as the insufficient of tutors, and infirmity of Undergraduate Tutorial System and so on. It is necessary to do some work to perfect Undergraduate Tutorial System. Through the investigation of Undergraduate Tutorial System implementation in College of Economic and Trade of Agricultural University of Hebei, Analysis the problems of the current tutorial system and propose coping measures.

The Course design for algorithm analysis is a compulsory course of practical teaching. From the theoretical study, experimental design , standard of evaluation and cultivation of innovation, it summarizes the effect that algorithm analysis has on improving students' Comprehensive ability.

Course project experiment plays a very important role in master student embedded system software education. The paper gives the design and implementation solution to a Chinese character text editor for embedded system, including requirement analysis, function design, task division, main process flow, Chinese character process, man-machine interface layout and test results. This course project can be used as a template for embedded system software experiment.

Teaching with the virtual network system is very important in modern teaching mode with its specialties of updating fast, high capacity and easy interaction. The virtual teaching network platform was constructed for the applied chemistry special English based on campus network in order to enhance students learning passion and initiative by the network. Through this virtual teaching system, it could answer online, deliver the newest chemical information, and help more students understand the applied chemistry special English knowledge. The system is characterized with easy used and management, extreme extensibility, stability, safety and so on.

A comprehensive questionnaire was taken in the faculties and students of engineering subjects. By analyzing the drawback of current engineering specialized course examination, a new pattern of examination is proposed related to contents of examination, methods of examination, types of examination questions and grading standards. The new pattern of examination was tested in typical courses. It is found that the all-process assessing system, open-book and half-open-book examination should be adopted. The scope of examination contents can be broadened. The examination questions should be comprehensive, practice-oriented and open-mind. The students’ practical ability can be checked by the questions of experiment, design and research. By using the new pattern of examination, the teachers and students would be guided to focus on the ability of comprehensively applying engineering knowledge and analyzing and solving specialized problems.

Compared with mechanical and electronic instrument, computer technology in psychological experiment teaching has obvious advantages. A variety of experimental software has been used for different types of psychological experiment teaching. Computer technology has improved the efficiency and quality of psychological experiment teaching obviously. At the same time, it has some shortcomings. The feasible way is to establish a teaching model of computer-based experiment complemented with instrument.

In the process of rapid development of the computer network, the network security has been paid more attention. The essential nature of network security is the information safety on the internet. Primary studies have been done in this paper on the aspects of information encryption technology and the network security strategy.
