The results of the study show that the implementation of regional language preservation and development programs in the city of Palu issued a number of regulations, namely in the primary school level curriculum the existence of subjects using language regions, naming street names with BDK and broadcasting tv shows using local languages, the proper implementation of a program is the result of commitment and understanding of the implementers of existing regulations / policies and being able to make local policies to strengthen the implementation of conservation and development of regional languages in the city of Palu.

Achievement goal setting and self-efficacy are two critical variables influencing learning achievements. Many scholars have studied the relationship between two variables by correlation analysis, regression analysis or path analysis. These methods, however, neglect the measurement error at all, which are inconsistent with the reality. Through a questionnaire survey among 266 first-year academic engineering graduate students, this study aims to clarify the relations among achievement goal setting, self-efficacy (SE) and English learning achievement (ELA) of engineering graduate students. Integrating the advantages of conventional statistical methods, Structural Equation Model (SEM) not only takes the measurement error into consideration, but also could study the structures of constructs and the relations among them at same time. The result shows that: 1)Achievement approach goal has a direct positive influence on English learning achievement, mastery approach goal and performance avoidance goal having direct negative influence, and mastery avoidance goal hasn’t obvious influence on English learning achievement; 2) Mastery approach goal has the best impact on self-efficacy, while performance avoidance goal has the worst impact on self-efficacy; 3) Self-efficacy, a mediating variable between achievement goal setting and English learning achievement, could improve English learning achievement efficiently.
