The Development Of The Internet Test System In Continuing Education

The mankind will enter the information society in 21st century, the knowledge becomes the key factor of the social productivity, economic competition; The knowledge renewal speed is so fast, the people should study hard and then can catch up with the social development .The experts predict that the stuff should be trained at least every 5 years . Therefore, the education and the training under this kind the of background is not only the need before employment but also the request of the social qualified labor force, the scale of continuing education is extending continuously, the continuing education college of the high school established so many stations everywhere, but it is limited by the place, space, the teaching resources, and bring many inconvenience for teaching and managements. Making the computers and the network techniques apply in continuing education and management system, it is the need of continuing education to develop and the demand of school , is necessary means of the reforming education mode, teaching research and management level. Examination is essential part of teaching process. Making a reasonable examination mechanism, exploring the student's interest in the study, improving students'abilities in analyzing and solving problem, realize the educating aim " knowledgeable, able, quality". The examination of the education reform, including setting question, investigating, grade examination papers etc.. Building a set of large-scale of database network examination system has great significance. At present, there are a lot of domestic examination system research to the network, but each kind of examination system still has its professional limit .there is not a set which is suited for the continuing education completely .Moreover, the network safety problem of each system is still very serious. The abroad also studies the network examination system broadly, the most important example is the ETS( the America education Test Center) which hold the examination GRE( American graduate student entrance examination) , it makes the examination so easily ,that means you can try it every day but not take examinations twice only in original every year . With the development of network, No paper transaction and no paper examination will be paid attention to by the people more and more .our country is developing the modern long range education strongly, making the teachers and students be able to break limit of time, space, region...etc. .So, it will be more and more high request of the examination, the traditional examination method also will change direction toward network gradually . The Web technical network examination system can based on the internet which spreads all over the world, so the examination can be held in native enter, also in the foreign land, expanded the region and adroitness of the examination , the test paper can be born according to computer immediately , can avoid the examination prediction; And can adopt standard test questions , thus use the calculator to judge them so efficiently ;Can also send to the result directly in the database, for the statistic and order. My object is to aim at all the problem , and create a method to conquer it and constitute a set of professional, training , study management sys tem .We adopted the system structure of the dynamic state, combine together traditional examination mode and the forerunner's network applications, set up the examination training terrace quickly, realize the management of the examination, training, study efficiently. The development of this system, considered the continuing education college well in teaching, the management process, to the special request that the students'examination, and try to consider both sides the procedure and expanding in the distance process, apply in the network examination with larger scope. The system adopts the mode of B/ S, is the abbreviation of the Browser/ Server, the browser/ server mode, is a kind of Web technique development to manage the mode of the software. All managements system procedures all carry in the server, need not to carry to install any procedure at the customer, the customer needs to pass the customer to carry the browser logging server only to carry out continuing education in the network examination system .Building up three layer system structures, including customer's browser, server, the database system, negotiate according to the HTTP, TCP/ IP, face to the Internet network service, synthesize several techniques of browser, network, database...etc.. The operating system of the network adopts the Windows 2000 Servers or the Windows NT servers, and installs the IIS( the Internet Information Server), using the ASP( the Active Server Pages, thedynamic state server web page) technique to carry out the data .ASP circulates to carry in the server, need not edit and translate, carrying the script language through a server engine of hermeneutic, the dynamic state produces the WWW page to deliver the customer to carry the browser also. With the development of the system, carrying out the following functions: 1, A database management system of the distributing type A management of the distributing type owns the very high price , teachers can use each machine to make out questions, work more efficiently; Strict legal power management, the different customer own to the category, a dissimilarity of legal power, the biggest limit guarantees the safety. A type is abundant, supporting the single-item choice, several choices and judging; 2, The intelligence of constitution The teachers need the simple strategy of constitution only, sampling a book to wrap from a database according to a strategy then, the examination is on the scene a book, the assurance equity of the examination, also can make use of a strategy automatic born several examination papers, try book to carry on the adjustment to each one, guarantee to examine science of the valuation, lower the teacher's a difficulty. Born calculation way of a database: Open a database first, then read the topic amount of data of request to save for the count in a database, then born a 1 to the count random few temp, this is the temp way, if we have never already picked out, it is chosen .Whether each topic was picked out by the current examination paper or not is in the mark word segment within the existence database. 3, Simple examination platform It can be competent and complicated examination environment, supporting the no dish to stand, computer terminal, changed the engine room of high installment, match actual circumstance of everyplace; Test the ex-preparation work is very simple, need to be wrap from the city area net or native ducting examinee and try book to wrap only, can start the examination immediately; Adopt various authorizations safety mechanism, various examination data...
