Noise, an important factor which impact on the performance of ultrasonic online testing system, has a direct influence on the signal-to-noise ratios level of ultrasonic signal acquisition. Noise problem of grain ultrasonic online testing system has been studied in this paper from two aspects, theoretical analysis and engineering practices. In this case, we can solve the noise interference problem in ultrasonic online testing system, and improve the performance of system and signal-to-noise ratio of signal acquisition.

Function Module

With rapid development of internet, various applications based on internet are increasingly highlighted. In the teaching of quality and technology supervision system, there are more and more businesses to use computer and the theory can be combined with practice to complete work with strong profession including inspection and enforcement. It requires staff in the system to learn theoretical knowledge and practice a lot to master knowledge really and play a role in practical application. In the current education and assessment mode, real level of staff cannot be assessed really. In terms of level in the practice aspect, it cannot guide staff to learn these courses with effective means. The online testing system based on Web comes into being under the circumstance. It gradually develops with network technology and database technology. It can test staff at any time with the network, stretching traditional testing room; in addition, network resources can be utilized effectively to service quality supervision cause in a better way.

This paper aimed at constructing a two-tier on-line testing system. Questions were designed based on integration of concept cartoons and multimedia in hopes that the unexplainable contents of an object can be appropriately represented and interpreted through the means of concept cartoons, and that student’s understanding of the questions and interests in test taking can be effectively enhanced through pictorial presentation of concept cartoons. This system was to construct a testing tool through which tests were conducted to explore third graders’ magnetism misconception. The outcomes indicated that incorporation of concept cartoons in multimedia on-line testing can improve accuracy than traditional written test on paper. During the study, 14 magnetism misconceptions entertained by the pupils were identified and classified. Further, the on-line testing tool can attain satisfactory results in system utilization, animation design, attracting students’ attention and enhancing their understanding of the questions. It demonstrated the fact that integration of concept cartoons with two-tier on-line testing can improve question comprehension and students’ attention.

The testing system designed by us aims at campus users. It can be considered as a subsystem inside the campus web, which not only can save papers to alleviate the schools expenses but also provide references for macro management of teaching for the administration with the help of analytical function of scores generated by the system.

Further Development

<span>An online testing system developed for entry-skills testing of first-year university students in algebra and calculus is described. The system combines the open-source computer algebra system </span><em>Maxima</em><span> with computer scripts to parse student answers, which are entered using standard mathematical notation and conventions. The answers can involve structures such as: lists, variable-precision-floating-point numbers, integers and algebra. This flexibility allows more sophisticated testing designs than the multiple choice, or exact match, paradigms common in other systems, and the implementation is entirely vendor neutral. Experience using the system and ideas for further development are discussed.</span>
