Design And Implementation Of An Micro Dictionary And An Micro Test Database For The Operating System Course

In order to assist the operating system course teaching reform and examination reform,introducing flipped classroom teaching and implementing fragmentation learning strategy,this paper designs and implements a micro dictionary which consists of knowledge points of the course of Operating System, and a micro test database which consists of test items of the course. A prototype website has been developed and used in the process of teaching and exams.The main contributions and innovation points are:(1) completed the construction of courses on operating system micro dictionary;(2) design and implementation of courses on operating system micro test database;(3) the development of the operating system programs and micro test database dictionary website.Hand-built operating system knowledge vocabularies, design and implement a thesaurus automatic construction algorithm, test the effectiveness of the algorithm. The design uses a micro dictionary Promise hierarchical coding, it is beneficial for a variety of knowledge granularity control. Design of the relationship between words, including hierarchical relationships, synonymous relations, an integral part of the relationship, the other relationship. Given the knowledge necessary for management of the function.Micro test database design using open classification methods, currently designed and implemented multiple-choice questions and algorithms class two top-class category, the algorithm class design and implementation of process scheduling algorithm, page replacement algorithms, and disk arm scheduling algorithms incorporated in the teaching process The actual use of these algorithms, on the one hand is to assist the teaching of knowledge in the classroom, on the other hand the use of these algorithms in periodic assessment exam, have achieved good results.Based on the above work and practical application on the further opening of the courses on operating system micro dictionaries and micro test database website, using free landing approach for teachers and students who use.
