Three dimensions of PLC which comprehension, readiness and strategies in PLC were analyzed by using SPSS and AMOS. Three hundred sixty students and five lecturers involved as respondents. Correlation analysis and structured equation modeling were used to answer the research objectives. Qualitative data as the predictive model achieved a good fit value of RMSEA=.055, GFI=.980, CFI=.981, TLI=.983 and Chisq/df=2.164. Interview data of 5 educators showed that decency was the main key theme in improving student language learning achievement. The implementation of PLC that related to language as well decency learning had given a new approach in teaching, particularly for educators and students in a language course.

Results showed that there were significant values derived from the relationship between comprehension and language learning (r=.401, p=.000), the relationship between readiness and language learning (r=.541, p=.000), and the relationship between strategy and language learning (r=.891, p=.000).
