The Preliminary Study In Internet-based Machine Design Course Computer Aided Instruction

AbstractComPuter Aided InstrUction (CAI) is one of the most advanced.ways in modern education technology This paPer mainly discusses theaPplying of comPuter network technology research in machine designcourse insmiction. To introduce the adVanced netWork technology inCAI into machine design course insmiction is one of the imPortantreforms of our university in the 2l st centuryIn the intemet-based machine design course CAI, the leaming pallof the system mainly uses HTML static web pages for students'primarily leaming stage, and the practicing part uses web-basedcomPuterized adaPtive test, which is based on Item Response Theory fOrdynaAnc tests, through which students will effectively deepen theirimPressions on what they have leamed.Because machine design course always have a 1arge quantity ofsubjective questions with calculations and analyses, this paPer uses thebolt-verification problem as examPle and makes primary researches inthe distingUishing model of subective questions with the fuzzycomPrehensive aPpraisal theory and the concept of satisfaction degree infuzzy mathematics. It's satisfying in settling the bo1t-verificationproblem.In convenience to the discussion between students and teachers, thereal-time comrnnication module in the system provides BBS,Chartroom and web-based Email, which makes the communication more easily.
