Your story matters Paola Uccelli studies socio-cultural and individual differences in early language development and in academic literacy. With a background in linguistics, she explores how different language skills (at the lexical, grammatical, and discourse levels) interact with each other to either promote or hinder advances in language expression and comprehension. She is particularly interested in the challenges and possibilities faced by struggling students as they try to learn the academic discourse valued at school. Her current research addresses questions such as how struggling students expand their academic vocabulary and how they learn to use a variety of discourse structures flexibly and conventionally for diverse communicative purposes.

LANGUAGE OF ACADEMIC WRITING 2
Abstract (144 words)Beyond mechanics and spelling conventions, academic writing requires progressive mastery of advanced language forms and functions. Pedagogically-useful tools to assess such language features in adolescents' writing, however, are not yet available. This study examines language predictors of writing quality in 51 persuasive essays produced by high school students attending a linguistically and ethnically diverse inner-city school in the Northeastern U.S. Essays were scored for writing quality by a group of teachers; transcribed and analyzed to generate automated lexical and grammatical measures; and coded for discourse-level elements by researchers who were blind to essays' writing quality scores. Regression analyses revealed that beyond the contribution of length and lexico-grammatical intricacy, the frequency of organizational markers and one particular type of epistemic stance marker, i.e., epistemic hedges, significantly predicted persuasive essays' writing quality. Findings shed light on discourse elements relevant for the design of pedagogically-informative assessment tools.
