Most U.S. colleges and universities expect students to improve their writing ability by taking first-year composition (FYC) courses. In such courses, non-native English (L2) writers with diverse language backgrounds study alongside their native English (L1) speaking peers. However, it is not clear how different these populations are in terms of their language development over time, leaving questions unanswered about whether L2 writers develop more or less than L1 writers in an FYC curriculum. To investigate, we compared 75 L1 and L2 students’ written accuracy, fluency, and lexical and syntactic complexity over the semester of an FYC course. Data showed that L2 students had significantly higher rates of language error and less fluent and lexically complex writing compared to L1 writers. Moreover, L2 student writing became less grammatically accurate over 14 weeks despite showing greater fluency and syntactic complexity. These results suggest a need for plurilingual pedagogies in FYC that embrace diversity and inclusion while also providing L2 writers with instruction on socially powerful and dominant linguistic forms.

Students in first-year composition (FYC) courses are expected to control the mechanics, vocabulary, style, and grammatical accuracy of their writing. Yet language development support, particularly that of grammar instruction in US FYC courses, has largely disappeared in recent decades, due in part to suppositions that students implicitly know grammar. This assumption is problematic given the increasing number of multilingual writers enrolling in US schools with observed needs for explicit language instruction. The present study explores whether first- and second-language writers of English perceived a need for language instruction and whether they wanted or expected it. Students from 12 sections of FYC were asked in surveys and interviews about their prior language learning experiences and current self-perceived language needs and then were asked to complete one of two self-directed language development projects (LDPs): an online, self-selected grammar and usage study project or journal entries focusing on vocabulary/style in texts they had read. Student work was collected, analyzed, and supplemented with students’ end-of-term observations and preferences about self-directed LDPs. Our findings reveal that students overwhelmingly wanted and expected language instruction and were largely positive about both types of LDPs, but they felt that language instruction should be offered in multiple delivery methods beyond just self-study. With these findings in mind, we offer pedagogical suggestions for addressing the perceived and real needs for language development of linguistically diverse FYC students.
