摘要：This study investigated and compared the scientific concepts of hearing and deaf students of grade VIII. For this purpose a curriculum based test of scientific concepts was developed. Pilot study was conducted on 15 hearing and 15 deaf students in order to select the items on the basis of item analysis. Initially 70 items were developed. After item analysis 32 items were selected. These items were administered on 50 hearing and 50 deaf students in final study. The data analysis showed that hearing students are more proficient in scientific concepts as compared to their deaf counterparts. No difference was located in the scientific concepts of the participants on the basis of their schools. The possible causes of poor performance on the behalf of students with deafness are poor facilities such as science labs and traditional teaching methods.
