Nigerian Science Teachers’ Perceptions of Effective Science Teaching and their Classroom Teaching Practices in Junior Secondary Schools in Lagos State, Nigeria

This study explores science teachers’ perceptions of effective science teaching and their classroom teaching practices. The study was carried out from a population of junior secondary schools in Lagos State, Nigeria. A purposive sample of 78 basic science teachers selected from 61 junior secondary schools from three Education Districts of the state was used for the study. A research instrument tagged effective teaching characteristics questionnaire (ETCQ) was used to elicit information from the teachers. The questionnaire has a test-retest reliability coefficient of 0.83. Data collected were analyzed using frequency counts and simple percentage. The findings indicated that the science curriculum used in schools was overloaded with content to be memorized by learners for examination purposes and that most science teachers engaged students mostly in explanation and demonstration, whole class discussion and note copying. The findings further showed that effective science teaching is characterized by student-centered activities associated with students being attentive, reading notes, doing homework, asking and responding to questions and engaging in regular hands-on practical inquiry-based activity and carrying out their own observations among others. Finally, recommendations for improving science teaching for junior secondary schools in Lagos State were proffered.
