Abstract
This work was conducted to determine the impact of class-size and field trip on academic performance of biology students in senior secondary schools in Oke-Ero Local Government Area, Kwara State, Nigeria. The study raised two (2) research questions and three hypotheses to guide the study. A survey descriptive research method was adopted for this study. The population for the study was all the biology students in secondary schools in Oke-Ero Local Government Area, Kwara State, Nigeria. A sample of 480 SSS II biology students was selected using simple random sampling technique. The data was gathered with the use of structured questionnaires and proforma. The findings of the study revealed a significant impact of class size on academic performance of biology students in senior secondary schools. It also found a significant impact of field trips on academic performance of biology students in senior secondary schools. Furthermore, the study found a significant relative impact of class size and field trips experiences on students’ academic performance in biology. From the finding of the study it was recommended among others that school authority and teachers should ensure that the number of students in a class should not exceed 35 and encourage field trip activities for students’ learning. Also, School administrators must decongest the overcrowded classes in the school so that the students can learn better and ensure that the students go on a field trip at least once in a term and the school authority should encourage and support both parents and teachers.
