The present study provides an analytical overview of the effectiveness of modular package in learning Science. Educational technology offers solutions to tackle the problems of modern educational system. The paucity of challenging educational material, which will not stifle the creativity of the learner, is better met within modular scheduling. Yet the use of modular package have not found their place in the present day schooling in India, especially in learning Science for middle and high school’s students. So the modular package on a concerned topic of Science i.e Air has been developed and tested for effectiveness in an experimental set up of 60 students using control-experimental two group design. by the investigator. It has been found while the low achievers can attain improvement in learning, the high achievers can develop competency through this approach. While the educational wastage could be eliminated, the productivity and accountability of educational system could be maximized through modular scheduling
