In a first step, this report describes the increasing importance of writing skills for modern engineering careers/professions. The authors show that cooperative interdisciplinary writing is particularly relevant in this field since, in the course of project communication, multiple occasions to write arise that eventually lead the project members to negotiate what should constitute the final project document’s contents, style and form. However, as most curricula for engineering studies at German universities neither include the teaching nor the facilitation of such writing skills these must consequently be acquired in extracurricular courses. The project TextING addresses this desideratum in that it introduces students to central aspects of academic and professional writing at an individual level which is then complemented by cooperative writing tasks so that students eventually compose their own e-portfolio, assisted by online-counseling. The project’s main objective is to better equip the students for their professional and academic career.
