This study explores the gender-stereotyped beliefs and perception of secondary school teachersâ€™ in classroom practices. A total of 250 teachersâ€™ participated in this study. A self-administered questionnaire was used to generate responses from teachers on how gender-stereotypes are played out in their classroom practices. Data were analysed using descriptive statistics, one-way ANOVA and t-test. Results indicate that most of the teachers surveyed directly or indirectly promote gender-stereotypes. However, ANOVA test revealed no statistically significant difference between some demographic variables and the three aspects. From these findings, it is recommended that teacher education curricula for both pre-service and in-service must be permeated with opportunities to acquire gender sensitivity knowledge, skills and develop attitudes in classroom layout, use of resources, responsibilities for activities, discipline, classroom language and teacher-students interaction. In addition, Federal and States Ministries of Education need to develop textbooks and materials, establish mechanisms to monitor and evaluate education policy implementation from a gender equality perspective.
