CAI auxiliary teachingEducation and calculator extended education of the calculator assistance are ones of calculator technique are count for muches of applied one of the realms, and because decade to tiny machine technique, network technique, multi-media technique with correspond of the software technical development, promoted CAI and CBE fly to develop soon more.CAI and CBE have already become a very important and valid means of modern teaching gradually currently 一、The CAI is abroad of development general situation:Have started ushering in the calculator technique to education realm at the beginning of 60s since the fertile graduate school of the IBM company of 1958 the United States designed the first calculator teaching system, people start the research which learns from the method developing to combine together with actual calculator system, aiming at a different academics on various calculator systems, developing a some calculator extended education softwares as a kind of assistance means that the student is self-educated and review respectively.In 70-80s, the CAI gets development and expansion gradually, and correspond of the tool be developed, producing more abundant support system.The more typical applied system contain IIS and IIAS of IBM company, this is one is more typical of the CAI of large machine S370 supported system at that time.The contents includes the teachers teaching material writing, the student studies, the entity manages and examines system.There are also the systems PLATO-4s of the United States moreover, Sophie system, the TUTOR of the CDC company and the NATAL system of Canada etc.The American teaching expresses after testing a service center to the overall valuation of systems PLATO-4s in five teaching categories, such as calculation and living creature, chemistry, English, mathematics.etc. to can replace the teachers function part ofly.Develop etc. modern calculator technical development and universality along with the calculator network, tiny machine, multimedia and the modern software after the beginning of 80s, promoted consumedly a CAI development, and because of voice, elephant etc. multi-media technical application, make him have already gone deep into teaching gradually of each link, it is concretely expressed as follows:1. International ascend many universities all have already started to build up a CAI research center and provided student CAI to start up a condition gradually.2. Try a database, the database manages system, taking intellective examination systems etc.s all developed.The student can listen to a teacher explain in detail in the CAI laboratory, can also use to try a database to carry on to wait from the check.3. A little bit foreign companies trainings to employee have already been gradually trained by original concentration, change in order to adopt a CAI technique, is carried on a study from the CD-ROM by the employee itself.Reduced the expense of the company consumedly4. On the international teaching annual convention, the special subject discusses CAI each kind of problem.二、The CAI is in the local development general situation： The our country opens exhibition CAI to begin from 60s.Because of technique and the foundation conditional margin, make the CAI of each university inside the country of actual use start slower.Our country CBE and CAI research get behind with a flourishing nation, starting from 80s, from parts of teachers in the Normal University from follow the abroad advanced technical angle, start understanding, research and study CAI technique, up to the mid 80s after, along with tiny machine technical development, the Chinese characters handles technical maturity, for our country of the CAI technical development beat to descend foundation, our country of CAI technique the industry develop rapidly.To the end of 80s, many high schools all established the CAI advanced technique, various practical system one after another.Start from 85 years, convened many CAI seminars, carry on a research study to the CAI from various angle, and CAI teaching the development of the software is included in high school teaching instruction the work plan of the committee, being included in teaching material construction a plan in the meantime in.Suggest each school also at condition maturity, the establishment CAI software develops development organization.The formation develops, develop, expand and applies a dragon system. Nations teaching 委 has already drawn up concerning the regulation, opening the exhibition to the CAI work is an index sign ofwith school evaluation, start 211 engineerings in, is an essential condition that the application gets into 211 engineerings the CAI construction in each school.Pushed CAI to work consumedly for this of open an exhibition.Each school throws in a great deal of funds to use to purchase an equipments, building up a CAi base, taking out to adjust a personnel CAI rese
