In the recent years, students' engagement has been the focus of concern in the US. Various studies have found that students' academic performances were directly affected by students' engagement. In Hong Kong, research on this topic has not yet been found. This research aimed to find out how the behaviors of three primary school English teachers' affect their students' engagements.

Ways of data collection included: lesson observation, video-taping of classroom teaching, in-class tape-recording of the sample students, and interviewing the teachers and sample students.

It was also found that students' engagement is influenced by the following psychological factors: (1) autonomy, competence and relatedness of the Self Determination Theory, (2) self-efficacy, and (3) students' learning goal orientation.
