Abstract:
This study sought to determine disparities and associated factors in students’ performance in Physics and Chemistry at the Kenya Certificate of Secondary Education (KCSE) examination in Nandi North District. The research objectives included determining differences in students’ performance at KCSE in Physics and Chemistry, self-concept (perception) of, attitude toward, and perception of the usefulness of Physics and Chemistry as subjects. Students were classified according to gender, using a causal-comparative design. Majority of the students aged between 15 and 19 years. Three questionnaires were administered to the form four students, and KCSE results for the years 2000 – 2004 were obtained from the District Education Office. These were analyzed using descriptive and inferential statistics. We concluded that boys reflected better academic achievement as compared to the girls in both physics and chemistry. The boys and girls had comparable self-concept in physics. The girls had a higher self-concept in chemistry than the boys. This may suggest that self-concept does not influence performance in chemistry since boys still out-performed the girls in spite of the girls’ higher self-concept. With regard to attitude towards chemistry and physics, the boys and girls had the same attitude, mixed and single-sex school students had comparable attitude towards physics and chemistry. An intervention regarding the level of preparedness of primary school pupils in dealing with the challenges of learning Physics and Chemistry at secondary is recommended.
