Deficit theory - Language Across the Curriculum

The deficit theory suggests that students from lower socioeconomic environments enter school without the necessary linguistic resources for success. It explains that disadvantaged students often show high failure rates because they come from homes lacking verbal stimulation. The deficit theory is problematic because teachers' expectations, which can be influenced by this theory, have a large impact on how students perform. If teachers believe only certain types of students can succeed, they will teach in a way that self-fulfills that belief. Believing in the deficit theory can lead to poor student performance, increased delinquency, feelings of helplessness, and lack of interest in school.
