Effect of Infographs on Secondary School Biology Students’ Academic Achievement in Ecology in South-East, Nigeria

Abstract
The study investigated the effect of infographs on secondary school Biology students’ academic achievement in Ecology in South-East, Nigeria. The need for the study arose from concerns expressed by stakeholders, committed scholars and researchers on the poor academic achievement of students in Biology. The study adopted quasi experimental design. One research question and one hypothesis guided the study. The population of the study comprised 251, 755 senior secondary two (SS 11) students in South-East, Nigerian public secondary schools in the 2024/2025 academic session. The sample size of 228 SS2 students were used. The instrument for data collection is a 50 item multiple choice Ecology Achievement Test (EAT) with options A-D adopted from past West African Examination Council (WAEC) and Joint Admission Matriculation Board (JAMB) questions. Kudder-Richardson (K-R20) was used to determine the reliability of the instrument. Reliability index of 0.77 was established for Ecology Achievement Test. Mean and standard deviation scores was used to answer the research question while the Analysis of Covariance (ANCOVA) was used in testing the hypotheses at .05 level of significance. Result showed that students taught Ecology using infographs achieved higher than students taught with lecture method and it was statistically significant. The educational implication of the findings is that poor academic achievement of students in Biology can be improved with the use of infographs which enhances students’ academic achievement in learning Ecology. It is recommended that Biology teachers should use infographs to enhance students’ academic achievement in learning Ecology, especially where they cannot learn Ecological concepts in the field.
