The application of knowledge to new contexts (i.e., transfer) is a central aim of learning processes and has become a new focus of testing effect research. In a quasi-experimental design, we investigated the transfer of retrieval practice effects on English vocabulary learning on eighth-grade students (N = 182) by applying a typical testing effect…

Laboratory studies have routinely demonstrated that testing often leads to greater learning and retention than repeated studying. In the classroom, this effect has been replicated with memory and application tasks. However, studies of classrooms involving mathematical problem solving are sparse and have had mixed results. This paper presents the…
