| Abstract | Traditional practices of spacing and expanding retrieval practices have typically fixed their spacing intervals to one or few predefined schedules [5, 7]. Few have explored the advantages of using personalized expanding intervals and scheduling systems to adapt to the knowledge levels and learning patterns of individual students. In this work, we are concerned with estimating the effects of personalized expanding intervals on improving students' long-term mastery level of skills. We developed a Personalized Adaptive Scheduling System (PASS) in ASSISTments' retention and relearning workflow. After implementing the PASS, we conducted a study to investigate the impact of personalized scheduling on long-term retention by comparing results from 97 classes in the summer of 2013 and 2014. We observed that students in PASS outperformed students in traditional scheduling systems on long-term retention performance (p = 0.0002), and that in particular, students with medium level of knowledge demonstrated reliable improvement (p = 0.0209) with an effect size of 0.27. In addition, the data we gathered from this study also helped to expose a few issues we have with the new system. These results suggest personalized knowledge retrieval schedules are more effective than fixed schedules and we should continue our future work on examining approaches to optimize PASS. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
