Learning Levels of Grade V Students in Environmental Studies

The Department of Educational Measurement and Evaluation of National Council of Educational Research and Training (NCERT) is an autonomous organisation under the Government of India. This department conducts the National Achievement Surveys (NAS) at different stages of school education under the Sarva Siksha Abhiyan (Educational for All), a flagship programme of Government of India.The purpose of the NAS is to know the learning levels of students in different subjects across the states in the country periodically and provide inputs to the policy makers, researchers and others for improving the system.The present study of grade V was initiated in 2009 and data was collected from 1, 22, 543 students and 6,602 schools covering 35 States and Union Territories. Sample was drawn from government and government aided schools by using Population Proportion Sampling (PPS) and Simple Random Sampling (SRS) methods. Using multiple choice items three forms of test booklets were developed in each subject i.e., Language, Mathematics and Environmental Studies (EVS) using Item Response Theory (IRT). Moving away from Classical Test Theory (CTT), Item Response Theory (IRT) is used to obtain scaled scores of students. Students’, scores were calibrated on a scale of 0-500. For knowing what students can do, students’, ability and items difficulty was computed. The research findings in ,Environmental Studies indicate that the average achievement across the states varies significantly.
