The 'summer learning effect' (SLE) is described as a stall or drop in achievement over summer, especially in schools serving poor or 'minority' communities. There has been little research in Europe on the effect, and research internationally has primarily focused on the effect in reading, with minimal focus on writing. This paper describes the extent and nature of the SLE in reading comprehension and writing in second grade classrooms in Germany. The SLE was evident in both subject areas with all students experiencing lower progress rates over summer. In reading, students attending the high-income school progressed significantly more over summer than their low-income peers, while there was no significant difference in writing progress over summer. Literacy logbooks over summer and interviews with a subset of students provided information on how home literacy practices influenced the effect.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
