With a teachable agent system and a set of linguistically diverse comparison prototypes, we explore questions of proficiency with and preference for local language agents in two sites in the Philippines. We found that students in a higher-performing school produce more English-language math explanations at a faster rate than students in a lower-performing school, who were more proficient in their local language. However, these students preferred the English-language agent, while students in the higher-performing school had equal preference for agents who communicates in the local language. These findings demonstrate the complex interactions between language and engagement in AIED systems.
