Research And Realization Of Coursewares' Colour Consulting System

Along with the wide application of computer network education, courseware universally spread to class teaching. Exquisite page designing and reasonable colors' matching can change the abstract, boring teaching contents of courseware into vivid, rich and artistic appeal ones, so as to create a relaxed learning environment. Color is an important part of courseware interface. It can be used to express theme and feelings, spread teaching content, attract students'attention, foil and render teaching atmosphere.Based on the investigation and analysis of relative literatures, this paper firstly analyzes the situation of the courseware using in class. From students'perspectives, it exist the following problems:lack of courseware color contrast and color coordination; lack of color used to highlight subjects; difficult coordination between courseware contents and feelings expressing through colors, etc. From the teachers'perspectives, there exist the following doubts:how to fully get courseware color knowledge; How to quickly get the color with tie-in principles; How to make use of color factors to make good courseware. Based on the situation talking about, this paper puts forward a courseware color consulting system solution to explore the establishment of the system model, the realization of the related technologies, the matching algorithm, the detailed design and implementation of each function. Finally through teachers'trial investigation and analysis of the system, this paper completes the assessment of the system.The courseware color consulting system uses SQL Server as its back-end database, chooses Delphi as its development tool. After detailed analysis of the relating data, we built a courseware table, a user table and an exercises table etc. Based on the establishment of the database,we built Windows visualization interface, write the Lord code and use ADO through the SQL language finally achieved various data updating operation.The main feature of the system embodied in two aspects as following:(1)It's mainly for specific practice, with teaching courseware as its center, using multilayer structure to make many function placed in middle business logic layer, in which realized the main functions of the system and the operation of connection pool of system database, operation and releasing attachment.(2)The system makes the various interactive widgets needed in general courseware and the frame structure of the whole courseware fixed in the development system. It separates the content of the courseware from the structure of the courseware, and makes the courseware structure intelligent and universal, which can generate the material contents prepared by teachers into courseware automatically, making the material reusability and sharing,so as to improve efficiency for developing courseware greatly.
