| Abstract | This study was carried out in the chemical teaching laboratory with new graduate students while they were guided to develop pedagogical content knowledge, PCK. PCK is expertise that demonstrates a combined knowledge of pedagogy and disciplinary subject matter; since chemistry is the discipline, the abbreviation, PChK, is used. Laboratory teaching functions for student learning entail guidance of chemical techniques, and abstract chemical concepts relevant to the lab experiment, that is, chemical explanations using concepts conceived by chemists rather than perceived, e.g., atoms and chemical bonds. Instruments were built with constructivist content and attained construct validity and internal consistency to measure teaching performance. A factor analysis reduced fifteen constructs to three forms of PChK, whose names reflect the level of chemical knowledge and pedagogical sophistication required. Mentoring activities were labeled as PChK-0. PChK-1 represents procedural knowledge to manage a chemistry laboratory. PChK-2 represents devising or generating transforming explanations connected to the students. knowledge and previous experiences. A .transforming explanation. is defined as a discipline-specific illustration of how people in that discipline think about a disciplinary process, which is linked by the explanation to students. thinking about that same disciplinary-related process. PChK-3 guides students in chemistry-specific reasoning and generating transforming explanations for themselves. Examples of PChK-2 and PChK-3, using two chemical topics, are provided. [Chem. Educ.

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.
