Constructing a closed-loop teaching model that supports each other between the two knowledge systems of “English language” and "professional technology" is one of the important means to improve the teaching quality and enhance the teaching level of English thesis writing courses for engineering graduate students in the era of “new engineering”. This article uses KPCA based technology text Chinese to English translation quality classification and evaluation method as the main tool, and designs a knowledge feedback loop that enables rational thinking of data mining to serve the emotional process of English writing. Based on the original "professional, interest and language" open-loop SPOC teaching model, a new closed-loop SPOC teaching model is created. At the same time, the main challenges faced by teachers in the new teaching model were discussed.
