Assess students' ability to design and carry out a corpus-based study comparing register features of academic research articles and popular science articles; tasks include constructing balanced corpora, preprocessing and annotating texts (tokenization, POS-tagging, lemmatization), selecting and applying analyses (keyword and frequency lists, collocation, n-grams, lexical density, nominalization, hedging, passive constructions, readability measures), using appropriate statistical tests and effect-size metrics, interpreting quantitative and qualitative results to identify register differences, and discussing methodological limitations and pedagogical implications.
