Research Paper (undergraduate) from the year 2021 in the subject Didactics for the subject English - Grammar, Style, Working Technique, grade: 1, 0, University of Freiburg, course: Introduction to Literary Studies, language: English, abstract: When doing an internship at a German secondary school, I realised English teachers are pointing out many errors to their students. Whether it is grammar, wrong use of a vocabulary word or their pronunciation, no matter their age or grade, the students are corrected whenever they say something wrong, but not once did I notice a teacher point out any prepositional mistakes to their students. But prepositional mistakes seem to be very common, I heard them in loads of sentences students tried to form on their own. As a result of this observation, I want to conduct in this study how many and what kind of prepositional mistakes are being made in the English language acquisition of German native speakers.
