| Abstract | Cognitive efficiency describes how individuals optimize limited mental resources to achieve improvements in learning and problem-solving. Research on expert performance and expertise has shown that expert designers structure the organization of cognitive actions more efficiently than novices. However, cognitive efficiency in engineering design processes has not been well studied because of technical limitations at the neurological level and lack of quantitative methods for analyzing information contained in designers’ cognitive processes at the performance level. The purpose of this study is to introduce Kolmogorov complexity to measure information contained in the changes of sketches generated by designers. The Kolmogorov complexity of each design move is calculated by the number of cognitive actions and transitions between different levels of information processing. In this study, sketches and verbal protocols generated by 15 participants were analyzed. Cognitive efficiency was determined by the quality of design outcomes and the expenditure of mental effort. The results indicate that Kolmogorov complexity is negatively related to cognitive efficiency; the higher the Kolmogorov complexity, the lower the cognitive efficiency. |

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.
