Development Of The Test Item Bank System For The CAD Skill Level Of Industrial Products

In 2008,to service the society preferably,and carry out the training and checking work of "CAD skill rank" deeply,China Engineering Graphics Society(CEGS)together with the International Society of Geometry and Graphics(ISGG)organized experts at home and abroad,decided "The Program of Exam for CAD Skill Rank" which is scientific and standard.It divides CAD skills into 2 parts and 3 ranks.The 2 parts mean "industrial products" and "civil and building".The 3 ranks mean: 2D computer graphics on the 1st rank;3D geometrical modeling on the 2nd rank;complex 3D model and processing on the3 rd rank.Although now we have already had the program as the reference,the relevant question bank is not be provided.So it is difficult to carry out the coming tests roundly.There are little data and papers to refer to on the internet and in the books,but they are not specific and general enough.And besides corresponding the measure points,to exploit the question bank we must find,norm,design and make many models,exploit each system in many different elements,same difficulty level and different contents.The workload is very heavy.It is obvious that this work has a very important meaning.It asks us do the research carefully and do the work deeper and deeper.In such a background,we put forward this research subject: The Analysis of CAD Skill Rank Testing Program in Industrial Products and the Exploitation of Its Question Bank.This article labors all the items' points in the program.We designed corresponding question types,and exploit "The Question Bank System of CAD skill Rank Testing in Industrial Products," on the foundation of VB High-level Programming Language.The system includes 3 ranks and 18 elements in 18 question types,exploiting 540 questions gathering into a question bank system.The system has the function of browse,adding and deleting,search,modification,test paper composition,and so on.It builds a good foundation for the effective linking up of doing the testing largely,quickly and expediently,for the testing's quick,expedience,objections,justice and equity.In the meanwhile,dramatically promotes the testing's network,electronic,paperless,standardization and automation.
