This study examined the extent of perspective taking and language features represented in secondary students' text-based analytical writing. We investigated: (1) whether perspective taking is related to writing quality, accounting for language features in writing; (2) whether students' English learner status is related to perspectives represented in their writing; and (3) whether the relation between perspective taking and writing quality differs by the level of language features (e.g., syntactic diversity, appropriate word usage, and tone). Secondary students' text-based analytical essays (N= 195, Grades 7-12) were coded for perspective taking and language features and analyzed using multiple regression. There was a higher frequency of own-side perspectives than dual perspectives. Dual perspective was related to writing quality after accounting for student demographics and grade levels. However, the relation was no longer statistically significant when language features were accounted for. English learners exhibited significantly less own-side perspectives compared to their English-only counterparts, but there was no difference in dual perspectives, which might be due to overall low frequency of dual perspectives represented in students' text-based analytical writing. The findings suggest the roles of both perspective taking and language features in quality writing. [For the corresponding grantee submission, see ED623455.]
