Is ‘more’ really more?: Results of a study on extended German grammar teaching

Abstract Starting from general problems of teaching grammar in the subject of German language as well as from basic assumptions of so-called ‘more-is-more’ didactics, we discuss demands to continue teaching grammar after the eighth grade (in Germany, that is the eighth year of school). We then present a quasi-experimental study which was carried out in grades 8 to 12 with the same participants for the purpose of finding out whether providing additional and repeated grammar teaching in the subject of German language even after the eighth grade results in improved and explicit long-term German grammar knowledge. At least at one measurement time point during the study, N = 821 students from six different schools were participating. As a crucial result it turned out that additional and repeated grammar teaching resulted in an improvement in explicit grammar knowledge both during individual grades and across grades. These study results support the demands of ‘more-is-more’ didactics, they however require long-term assessment concerning a number of problems, which are discussed.
