A study conducted by Lynn and Douglas Fuchs and colleagues looked at the effectiveness of interventions that combine training on working memory (WM) and word-problem solving (WPS). The four interventions were as follows:
- Intervention 1 – general training on WM
- Intervention 2 – training on WPS without WM training
- Intervention 3 – training on WPS with math-specific WM training
- Control group – no intervention
