Introduzione o prefazione

This study reviews literature regarding the effectiveness of different methods for providing written feedback through a computer-based assessment for learning. In analysing the results, a distinction is made between lower-order and higherorder learning. What little high-quality research is available suggests that students could benefit from knowledge of correct response (KCR) to obtain lower-order learning outcomes. As well, elaborated feedback (EF) seems beneficial for gaining both lower-order and higher-order learning outcomes. Furthermore, this study shows that a number of variables should be taken into account when investigating the effects of feedback on learning outcomes. Implications for future research are discussed.
