| Abstract | In this work, we use a graph analysis tool to measure how student-created mind maps reflect learning. Mind maps consist of words and connections between words, and this visual tool helps illustrate how an individual understands how these words connect together in a field. From an analysis standpoint, mind maps are graphs consisting of nodes connected by edges. In the fall of 2011, students created three mind maps over the duration of a digital system design course, and at each of the three intervals, these mind maps were created with the same 20 terms that were introduced throughout the course. Each student's mind maps were then digitally encoded and analyzed using a modern graph analysis tool called GraphCrunch II. Our results show that a simple analysis of graph density is a poor indicator of learning since this metric does not capture a graph's structure, and it is this structure that reflects meaning and understanding by the learner. Instead, a metric called relative graphlet frequency distance (RGF-distance), which is calculated by comparing a golden mind map (expert created mind map) to each of the students mind maps, is used to analyze each students understanding of how these words relate. Our results show that learner's mind maps decrease in RGF-distance over the period of the course, and this means that the students are building graphs more similar to that of the golden model. We, also, see that the RGF-distance over the set of students compared to their grades on an exam or overall grade in the course has some correlation, meaning that these mind maps relate to grades in terms of the learners understanding of vocabulary, but the correlation is not strong. The ultimate goal of these tools is to provide the learners with a method of getting automatic feedback on their understanding as well as learning progress in particular topics. |

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.
