The site www.ePrayogLekha.org 'Undergraduate Courses' deals with a paperless practical manual cum notebook in which the students of Undergraduate Level B.Sc (Hons) Chemistry and B.Sc (Hons) Physics of Delhi University and BS(research) of Indian Institute of Sciences Bangalore can feed their real time observations electronically after performing experiments in the laboratory. The classroom version of this site has the theory and procedure of all the experiments reported in the DU Chemistry Hons and Physics Hons Syllabus based on Choice Based Credit System (CBCS) as well as IISc BS programme.
The students can register themselves for the courses they are studying in a particular semester. They will be provided with user id as well as password. The students come prepare in their regular practical class for a specific experiment to be done on a specific day. They will be given with some quick instructions by the teachers, if needed. The students will perform experiment in the laboratory and start feeding the observations in the ELMN in place of the present auxiliary note book. The students can perform calculations online through this ELMN and plot graphs, if required. The students can take pictures of the compounds they prepared in the laboratory and paste it in the notebook. They can also paste photographs, etc of TLC or paper chromatographs,etc online. The students can submit their results once they are satisfied with calculations, plotting, etc online.
The teachers can also register themselves. They will be provided with a user name and password through their emails after proper verifications. The teachers can interact with students for some kind of viva voce questions for all the students of their class. They can evaluate the experimental results 24x7 online and give credits to the students for different experimental results.
The present portal of Paperless ELMN can be used by the students and teachers of different institutions; schools, colleges, universities, etc after getting a verification message from the co ordinator. Therefore the first stage will be the registration of a particular institution co ordinator. Then the students and teachers of that institution will be able to register themselves.
