1、CAI auxiliary teaching Education 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 t
2、echnical 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 th
3、e 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 var
4、ious 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 sup
5、port 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
6、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
7、 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 consume
8、dly 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 cen
9、ter 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
10、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 consumedly 4. On the intern
11、ational 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 insi
12、de 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 80
13、s 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 C
14、AI 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,
15、 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 co
16、ncerning 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 exhibi
17、tion.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 research center.Open the exhibition CAI related and technical research in order to, the development of construction and CAI software and lesson piece of sup
18、port environment.The importance which makes the CAI become the school daily teaching to work gradually constitutes part. 三、The CAI is in the important meaning in the modern teaching: The CAI is people to make use of a calculator technique to develop the whole study resourceses, passing it, making ca
19、lculator and the persons hand over to work with each other way, attain a study new information to know, review old knowledge, control the purpose ofwith knowledge completely.The CAI machine can be used to replace a teacher to carry on each study of course, can be a normal regulations course the comp
20、lement means of the teaching.So, the CAI is an one of the very important meanses which opens an exhibition reform in education at present, convening for 92 years of national and high school working conference up, the nation teaches directors to open 轩 a comrade to point out while speaking of deeply
21、way of thinking of turning the reform in education with main target:Total of to say, is want according toface to a modernization, face to world and face to future of request, carry through education policy of carrying out the party completely, enlargement content of course, the strength ofwith teach
22、ing method reform, push forward the application of modern teaching means strongly.The application ofwith reform and modernization teaching means of content of course, teaching method is closely related. Use modern means well in the teaching, study especially and strongly with one of the important as
23、pects of expansion CAI reform in education.It will promote emolliently the strength of content of course, teaching method reform, push forward the application of modern teaching means strongly, push forward teaching method innovation consumedly, and even change existing teaching mode to a large exte
24、nt the change.The American technique assessed office to do to evaluate as follows to the CAI: 1. Face teaching a personnel to reduce at school, under class scale and then bigger circumstance, CAI may be use to come to cloth to control the most viable path in teaching ability. 2. Distributed to provi
25、de a kind of means with training for the teaching from the geography and the top of the fulfillment. 3. Allow learner at their convenient time study, and do to visit patients at home to break to their studies strategy and in time of reflection. 4. It can teach to suit an information more to the stud
26、ent for ages new thinking with new of problem-solving of way.Can see, support in the new calculator technique under of the CAI give the study this very big independent power, regardless in time, location, and the choices of study contents all provide utmost convenience.This rightness of currently ou
27、r country part of high schools provided one toward the conversion of credit system gradually viable and the condition of essential to have. 四、And the CAI related modern calculator technique： 1, Tiny machine technique.From 80s early and tiny machine development, the development speed of the calculato
28、r technique compares before sooner.Positive because the tiny machine flies to develop soon, making calculator the equipments head for a society very quickly from the laboratory appropriation, heading for every trade, heading for a family.At the flourishing nation, the each university students hand i
29、s one set tiny machine, also starting heading for a family in the domestic tiny machine.A great deal of CAI systems builds up on the tiny machine system.It is the hardware foundation ofwith CAI application. 2, The Chinese characters handles a technique.The word processings technique of the calculato
30、r is also CAI one of the foundation, the Chinese characters that is in China processing technique, and here on of word processing and various chart handle a technique, is also one of the CAI important foundations.The technical development of the Chinese characters processing was the calculator appli
31、cation of our country to lay foundation. 3, Multi-media and super medium technique.Super text should be the TEdNelson puts forward coming in 60s.The language righteousness network constituted tofrom the network of the traditional crunode and the point of contact namely.Can used for meaning the not-
32、line similar mankind associate memory structure.In recent years because of multimedia namely writing and voice, picture technique combine, can use to mean to live a new life to move, each kind of more complicated comprehensive information.The H.Maurer teaches to as follows of formula:The super text
33、is originally(Hypertext) multi-media(Multimedia)=super medium(Hypermedia) modern multi-media and super medium technique is develop high performance CAI it is thus clear that of one of the important foundation techniques. 4, The technique education of the calculator network and training are the impac
34、ts that the modern and new technique flies to develop soon bottom, face a new challenge.To everybody, studying will carry through life long.So, the obviously original classroom teaching mode goes impassability.But modern technique and information superhighway of the calculator network make the teach
35、ing process come out classroom, each learner can according to its time up, the possibility of geography, Be studying the contents needed anyplace.This is long-distance to leave teaching.The network technique provided very ideal technique support for CAI. 5, Artificial intelligence.The persons cognit
36、ion process is the learning process that the mankind know to the new information.Obviously, artificial intelligences research to CAI has a very important push function.Start in 70s, make the artificial intelligence academics, cognition academics and the thinking academics as theories foundation, stu
37、dy mankind to study and thinking process and characteristic with look for study cognition model so, the artificial intelligence is a CAI one of the theories foundations of research. 6, Other tools and technique.Study related tool and technique with CAI to still include(1) the development technique o
38、f the software of facing to the object namely O-O technique.(2)Each kind of word processing, picture and form processing, picture processing under the WINDOWS environment etc. tool and technique. 五、Establish the main thought of this system: Traditional teaching mode is a teacher, a chalk beats world
39、.The teacher teaches knowledge on the classroom, the student accepts knowledge on the classroom, and the different student accepts an ability also different, have of the student can listen to understand, have of know only superficially, but have of a little bit more possible then didnt listen to und
40、erstand, teacher to same knowledge point generally is will not repeat to explain in detail, for those students who dont understand but speech there is no way re- listenning to lesson, master knowledge, in the meantime because of only have book teaching material, teacher at the time of explaining in
41、detail knowledge can depend on a chalk to write down a related contents, wiping in addition to a little bit another contentses, this kind of writes to wipe, the process which wipes to write will give the student listen to lesson to result in to disorder, with go to make the study result give discoun
42、t greatly.Along with the fast development of the calculator and the calculator network, the reform which makes use of a calculator technique to carry on teaching resources and teaching means is certainly Be going necessarily of, the new teaching means will improve above-mentioned many irregularities
43、 consumedly necessarily, as a result produce development teaching lesson the viewpoint of the piece, usesyllabus for line, lesson originally is foundation, the teaching important point explains in detail right, applied simple, expand sex strong, easy maintenance as system the instruction thought of
44、the development while developing it.Word processing:Dont shine on to move book, writings describing is to the utmost simple and direct, increasing literalness layer feeling, is controled literalness manifestation process by user. Picture processing:Lesson piece beauty for making, adopted a great dea
45、l of small picture, these pictures werent big, cant presumptive guest usurps the role host, also handling for the picture form to some special form of writtens, the in order to prevent cant show in having no the machine of that form of written.The chain connects a processing:It established a great d
46、eal of chain to connect in the lesson piece, established particularly valid for forever withdraw a chain to connect, this can make the user can connect a be over study through that chain no matter in what circumstance.Animation processing:For heavy, crux, disadvantage in the calculate way adoption o
47、f the comprehension example analysis, the animation form play to show.The adoption grasps diagram software HyperCam to record animation an AVI document, making use of the COOLEDIT of the recording software will explain in detail process to record a WAV document, again the exploitation synthesize sof
48、tware TMPGEnc to synthesize it for the MPG document, making use of DirectMediaXtra software to load animation finally into the system.System design:Make use of the software AUTHORWARE of the multimedia development, designing can the convenient teachers and the students use of data structure CAI lesson piece.Attain result:The data structure CAI lesson piece, complete is in line with originally with lesson, and use in brief, convenience.Teachers and the students passing a CD can immediately use that.
