| Abstract | Understanding learner differences with sensors is increasingly important for effective learner modeling. Learner models based on a student's problem-solving actions and the automated interpretation of those actions have successfully advanced computer tutoring services. However, such transaction level actions provide insufficient detail about higher-rate cognitive variations, which may hold key information about individual differences in cognition and learning, and about factors that differentiate attention-switching strategies and instructional effects between individuals. To fill this gap, we have conducted a user study to investigate causal relationships between learners' expertise levels and patterns of interaction and attention during learning tasks by using an eye tracker and physiological sensors. In this paper, we validate our experimental test-bed built for inferring learners' cognitive processing states and diagnosing learning phases with sensors, and present initial results about expert-novice differences revealed in transaction level samples and sensor data streams. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
