The methods of vocabulary learning in teaching and the modes of vocabulary learning in teaching have diversified Aiming at the main links of vocabulary learning in college classroom teaching, this paper puts forward the design idea of a practical computer-aided system TCAS for vocabulary learning in college teaching, and uses vfp9 0 to reduce teachers’ repeated work and improve the quality of vocabulary learning in teaching. The database design adopts the classic case tool set Sybase PowerDesigner, and gives the main data table structure The experimental results show that when TCAS is used in the actual teaching of operating system and other courses, only a small amount of key information needs to be input or imported into each teaching link of vocabulary learning; At the same time, TCAS has a convenient user interface. In terms of the relationship between vocabulary richness and writing quality, vocabulary variability, vocabulary complexity and vocabulary density are significantly positively correlated with writing quality, and vocabulary errors are significantly negatively correlated with writing quality.
