| Abstract | Compiler design is an important subject in the computer science curriculum for undergraduates. In a typical Compiler's course, about 15%-22% of the total time is spent on syntax analysis phase (also called parsing techniques). A number of concepts are introduced to explain the internals of parsers, for example first set, follow set, item set, goto and closure set, parse tables and the parsing algorithms, making the understanding difficult. While parser generators (YACC and its variants) allow the students to experiment with grammars, the working of the parser generated by the tools is still opaque. We present ParseIT, a web based tool to help students understand the concept of parsing in an undergraduate Compiler Design course. Given a grammar, the tool generates multiple choice questions for concepts related to parsing. The tool evaluates students' attempts and provide hints for incorrect attempts. The hints are also generated in the form of specific questions about any correct choice that is missed or any incorrect choice that is selected. For grammars that can be parsed through the textbook LL or LR algorithms, an interesting form of hint generated is an input string that helps student identify incorrectly filled cells of a parsing table. The tool enables interactive and active learning of parsing concepts, resulting in a better understanding. |

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.
