ABSTRACT With wider application puter technologies in industries and increased popularization of office puter examinations puter knowledge and skills are hi曲ly regarded by the is a question requiring incessant researches and discussions that how to employ modem technologies to improve qualities and efficiency of regards way of testing administration, puter-based testing),wifla obvious advantages over PPT(paper pencil testing)in aspects of planning testing content,scoring,managing test—taking area, security and reusing items,is now gradually replacing PPT and ing the principal way of puter knowledge and ,auto scoring without manual es forth as a key technology for CBT. The author of this paper has been involved for several years in the development of CBT software of NCRE,all examination based on an open CBT system and advanced auto scoring technology for operation this paper,he chiefly investigates the technology Automation and its application in the auto scoring ofMS Office operation items in also invented the SAL using in the period ofcreating items, This paper firstly introduces the present situation of domestic and puter testing with a detailed classification parison of different types,and then reviews main scoring technologies for operation items employed in culTent the following,the author introduces the technology automation,the tree structure of Office documents,and than presents how tO realize the auto scoring of Office operations formulae are not tested in Word documents because they cannot be automatically scored by conventional scoring in this paper'the author investigates the XML-based Math Markup Language(MathML),analyzes the method of revealing and recognizing math formulae throu【gh MathML'and further introduces the construction of Mathematics Formulae Scoring System(MFSS).In Call transform math fonnutae into recognized code
