学习设计再生器的研究

RESEARCH ON LEARNING DESIGN REGENERATOR

为了提高LD(Learning Design)文件的制作效率和保证其顺利执行,在分析LD文件及其制作规律的基础上,开发了一个由LD搜索器和LD装配器两部份构成的LD再生器,其工作原理:首先,由LD搜索器搜索符合设计者要求的已有LD文件和部件,为设计者推荐最佳的可利用方案;其次,由LD装配器引导设计者对LD部件进行修改、验证;最后,LD再生器自动生成新的LD文件。实践表明:利用LD再生器制作LD文件,不仅降低了设计LD文件的复杂性,还减少了大量的重复性工作。

To advance the efficiency of LD （ Learning design） file＇ s facture and ensure LD file＇ s smooth execution, an LD Regenerator comprising the LD Searcher ＆ the LD Assembler is developed based on a study of LD file format and its facture rules. Its principles are： Firstly,the existing LD file and the LD component meeting designer＇s requirements are searched by LD Searcher, and the best reusable scheme for designer is recommended;Secondly,designer is guided by LD Assembler to modify the LD component and validate it;Finally,new LD file is automatic generated by LD Regenerator. Practice shows that the LD files made by LD Regenerator can reduce the complexity of LD file design and can reduce a great deal of repeated work when designing.
