The Design And Development Of Item Bank And Management System Of Occupational Safety And Health

In recent years, there have been a large number of occurrences of casualties in China, An important way of taking on a job by a certificate is considered to assure personnel's quality for the decreasing of casualties and a perfect credentials test system is required, while the present national credentials test system and method of the occupational safety and health is still undeveloped and the exam quality can't be assured. So the item bank and its management system of occupational safety and health (AQDB 1.0) were developed.This system mainly include: Reasonable national item bank and its management system of occupational safety and health were designed through researching the designing and construction of domestic and foreign item bank in safety and other courses. Management and maintenance function of item bank and its convenience. The adding, deleting, modifying of subjects, input of items and maintenance is very convenient. Items with pictures are available. Manually and automatically generating of paper and was provided. Practical and high-efficient algorithms of generating papers-genetic algorithms was developed. Management of item bank is multi-functional and convenient, new papers can be generated and current paper can be analyzed statistically and output at any time. Learning function was provided, the principle of memory curve was contained in the system and learning efficiency was improved for assisting the learning of learners. Realizing of test subsystem, learners can take a stimulated or formal exam.
