Research on extended education in Germany. A general model with all-day schooling and private tutoring as two examples

Although research on extended education is similar to school-focused research in some respects, in other respects it involves new research perspectives and questions. Our article presents an analytical model on extended education that is based on school-effectiveness research and the work of Fischer and Klieme (2013). We summarise selected research findings in two areas of extended education: all-day schooling and private tutoring. While much research has been done in the first area, there is a considerable lack in the second. Our model and the findings that we are reporting can be used to guide further research in the field of extended education. (DIPF/Orig.
