Data were obtained through interviews and the administration of a questionnaire. The participants were four Biology teachers (two males and two females) and 15 male Biology students of the school under study. The findings indicated that teacher gender and teacher instructional style impacted the academic achievement of the male Biology students, but not their achievement motivation. The male students preferred to be taught by female Biology teachers and achieved higher test scores in comparison to students taught by male Biology teachers.Case studiesGender issuesMale studentsBiology studentsAcademic achievementStudent attitudesSecondary school studentsTeacher attitudesSecondary school teachersTrinidad and TobagoThesis
