The Design And Implementation Of Intelligente Computer Aided Teaching System Based On C/S Pattern

In the present era, the science and technology obtains the more and more widespread application in society's aspects, simultaneously also in promotion entire society's progress and development.Along with our country higher education scale daily expansion, regarding undertakes the education and the scientific research duty university, the science and technology regarding raises the university teaching level, the rich university teaching method, raises the teachers level and so on each links and so on teaching and scientific research all has the vital significance.Then in now in university's teaching method and the method, computer aided teaching (CAI) already became an extremely important part.At present, in the nationwide scale university, most all already started the multimedia teaching, but uses the computer aided teaching system was not truly very many.But my school computer aided teaching start quite is late, but also is merely draws support the multimedia coursewares even is the PPT draft form carries on the assistance teaching, this and in the true sense computer aided teaching is far from.I want to do for my school computer aided teaching have the significance attempt, simultaneously also wants me in graduate student study period studies the knowledge can apply in truly the practice, therefore had the development to design this system the tentative plan.This system uses is the C/S pattern design, the database server end uses Microsoft Corporation SQL Server 2000 to take the database end, the client side uses Visual the Basic achievement to develop the language.The computer aided teaching system main function includes:1. User module this system has established three kind of users, respectively is the manager, the student and the teacher.The user module to the student, the teacher information carries on the maintenance, in which student and the teacher user only can examine and revise its myself information, the manager user may carry on the overall to these three kind of users the maintenance.If first uses this system, may when registering uses myself student number to carry on registers, after carries on the system, revises its myself information in this module, specially registers the password.2. Study module this module mainly aims at the student user establishment.Initial registers when the study may the free choice study content.After the study, after the choice practice or the test module test determined student's cognition model, then the choice correspondence study content continues to study.3. Test module this module mainly also aims at the student user establishment.After the student studies some unit content, may choose corresponding the unit to carry on the test.The system can act according to the test result, gives the next step study suggestion.4. Q/A module this module mainly is aims at, uses in explaining the student who student's question establishes to study the question.The student may propose own question, the system can establish some explanation content.If had not found the answer, then the student may the question through the E_mail form transmission for the teacher, the teacher be able to make as soon as possible the explanation, plays role which interacts to one kind of teachers and students.5. Teacher module this module mainly is aims at the teacher user to establish.In this module, the teacher must aim at the different cognition type hypothesis different course content.The hypothesis test topic, and gives the answer.Also wants the regular non-periodical renewal course content and the test content.This system design characteristic:1. Carries on the cognition ability the quantification, gives the study suggestion.But this system comparison stresses the student from the study process.Therefore, in the system rests on teaches the curriculum the program of instruction and the test program request, has established the student cognition ability quantification weight, according to student's after study test result, the system can give the study suggestion.This kind of study suggestion structural style for branched structure IF ...... THEN .......2. Uses in the teacher hand fully the existing resources, links teacher's PPT draft and the system.Namely:ShellExecute Me.hwnd,"open","POWERPNT.EXE","PPT filename", "", SW_SHOWThis sample system if changes into other curricula extremely to be also convenient, so long as will teach the curriculum the PPT draft link to come in, certainly will test the content and the cognition ability quantification weight will also need to make the corresponding adjustment.3. Uses Visual the Basic language development kit design take Visual Basic this curriculum as the example computer aided teaching system.Because this system has only made the small scope test in my professor's class and grade, and but this system particularity lies in using Visual the Basic development teaches VB this curriculum.I thought this also can enhance student's study interest to a certain extent, the student in the gradually study process can realize after I learn this curriculum I also have the possibility to design such system, but the teacher also can seep the system design gradually in the teaching process the thought, the method, this has also been manifesting our quality high special colleges and universities educational model--------Instantiation teaching.
