This study examines physics teachers' views on factors that contribute to the declining interest in physics among school students. A total of 190 physics teachers from 91 secondary schools and nine junior colleges in Singapore participated in this study, which used a survey instrument to seek their views. Rasch analysis was used to analyze the data. The findings showed that teachers are uncertain about the career prospects of physics graduates and are not very optimistic about the market demand for physics graduates. They feel that physics seems to be difficult and abstract to students. The perception that physics is for boys seems to be rooted in society. The teachers emphasized the importance of co-curricular activities and laboratory work to enhance interest of students in learning physics. We provide several recommendations to arrest the declining interest in physics at the school level. (Contains 4 tables and 1 figure.)
