The study deals with Activity-Based learning to improve students` outcomes in English language and Basic Science. The study examines how the use of the activity-based learning strategy enhances students` outcomes in the two core subjects taught in the upper basic levels in Nigeria. Quasi-experiment research design was used to conduct the study. The target group comprised six hundred and forty-three (643) Junior Secondary School Students (JSS II) in two selected schools. One Hundred and ten (110) were sampled using a stratified sampling technique. Self-developed instrument entitled `Basic Education Performance Scale` was deployed to assess the experimental and control groups` outcomes. The data collected were analysed using independent t-test. The study’s findings indicated that activity-based learning significantly affects the students` outcomes in English language and Basic science subjects. Therefore, it is recommended that teachers should promote active learning through the use of hands-on activities.
