| Abstract | Data Structures and Algorithms (DSA) courses are considered critical in any computer science curriculum. DSA courses emphasize topics related to procedural dynamics (how an algorithm works) and algorithm analysis (the algorithm's efficiency). Historically, algorithm visualizations (AVs) have dealt almost exclusively with portraying algorithm dynamics, and there are few examples of visualizations related to algorithm analysis topics. We have developed a new generation of visualizations that we term Algorithm Analysis Visualizations (AAVs) to convey algorithm analysis concepts. We present the motivation behind AAVs, and outlines a methodology for their evaluation. We present results from student surveys and the analysis of student interaction logs from the OpenDSA eTextbook used by several CS3-level classes during the period of Fall 2014 through Fall 2015. Initial results from Fall 2014 revealed that students were not spending enough time reading the algorithm analysis material presented as textual content. Our results from a preliminary deployment of AAVs in Spring 2015 showed that students interacted with AAVs for significantly longer than the control group spent reading the previous text-based algorithm analysis material. We will present additional results from our ongoing experiment in Fall2015 (control group without AAVs) and Spring2016 (test group with additional AAVs). |

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.
