Project Report from the year 2018 in the subject Didactics - English - Pedagogy, Literature Studies, grade: 1,3, University of Bonn (Anglistik, Amerikanistik und Keltologie), language: English, abstract: The present study was realised during the first phase of teachers' vocational training in Germany and seeks to observe the effects of morphological instruction in a class of the qualification level. A diagnostic test that was carried out based on some spelling mistakes in writing tasks during the first month of the training, suggested that learners lacked knowledge in some basic spelling changes in the area of derivational morphology. Also, when they were asked to draw lines between morphemes in some words, in order to control to what extent they can identify word components the degree of uncertainty was high. Given the fact that no explicit instruction on morphology ever took place in the class, it was decided to observe whether learners of higher classes can benefit from a morphological instruction and what conclusions can be drawn from the results.
