Research On Contextual Assessment Of Lexical Pragmatic Competence In Computer Environment

Language ability is a basic ability of people in modern society.The language test has developed continuously.There are more and more researchers paying their attention to language ability in communication.The present research was aimed at forming the evaluation scheme of Lexical Pragmatic Ability,and then realized the system of situational test to optimize the present Lexical Pragmatic ability test,contributing to setting up the standard of the test of Lexical Pragmatic Ability test in computer environment.This study set up situational evaluation method of computer from the linguistic context and the construction of interactive design test project.Then,we used computer situational evaluation methods,combined with the construction of situational evaluation environment of computer interactive technology,and improved the design of computer situational assessment program of Lexical Pragmatic Ability.In the evaluation of the implementation phase,we used speech recognition,speech synthesis and handwriting recognition technology,and used Visual Studio tool to develop Lexical Pragmatic Competence situational evaluation web program,constructed with role selection module,web test system module,feedback module and database module.We chose a part of the college entrance examination as a part of vocabulary test paper test and the other part of the college entrance examination test as the environment of computer system.After the trial and the interview,we found that compared with the traditional test,the Lexical Pragmatic Competence situational test was much more loved.At last,this study compared the paper test and Lexical Pragmatic Competence situational test after optimization.The results come out that Lexical Pragmatic Competence situational evaluation system under the environment of computer also has high reliability and validity.Not only could the system maintain the effectiveness of the original item,but also it could improve the situational level test and application level.
