EFFECTS OF CONCEPT MAPPING STRATEGY ON SENIOR SECONDARY TWO STUDENTS’ ACHIEVEMENT IN REDOX REACTIONS IN JOS NORTH, PLATEAU STATE, NIGERIA

Abstract

This study investigated the effects of concept mapping strategy on senior secondary two students’ achievement in redox reaction in Jos North, plateau State, Nigeria. The study adopted Quasi-experimental design of the non-equivalent control; group design. The population of the study comprised 3088 students for 2022/2023 academic session studying Chemistry as a subject. The Choice of Jos North Local Government Area is as a result of under achievement’s of students in WAEC Chemistry Examinations. A sample of 167 consisting of 82 female and 85 male Chemistry students were drawn from two educational public senior secondary school. Purposive sampling technique was used to select two public senior secondary schools that are offering Chemistry at SSII and have similar characteristics. Redox Reaction Achievement Test (RRAT) was used to collect data. The instrument used for data collection was not developed by the researcher, it was adopted from the West African Examination Council past questions and Answers. The test consists of 25 objective items. Mean and SD was used to analyze the collected data to answer the research question. While (ANCOVA) was used to test the null hypothesis at 0.5 level of significance.  The findings of the study reveal that there is significant difference in the mean achievement scores of students taught redox reaction using concept mapping strategy and those taught using lecture method in favor of the student taught using concept mapping. It was therefore recommended that Chemistry teachers should be encouraged to use concept mapping in teaching and learning to improve student academic achievement in Redox reaction.
