Abstract
A qualitative study of academic engagement of five high school students labelled mentally retarded describes strategies of student participation and non-participation, and teacher perceptions. These students were non-verbal or inarticulate, and functioned in an environment of competing formal and informal assessments of their participation and understanding in the academic environment. Teachers' informal assessments of student participation revealed how the students challenged the conventional categories employed by teachers. The examples show the power of educators' perceptions to reveal or obscure student engagement.
