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.
