Abstract
The study investigated the effect of infographics model on Senior Secondary School Students' achievement in Geography in Akwanga Local Government Area, Nasarawa State, Nigeria. Two research questions and two hypotheses guided the study. The study employed quasi–experimental research design involving non randomized pre-test, posttest and control group design. The population of the study consisted of 4556 (3223 male and 1333 female) SS II Geography students from 26 Senior Secondary Schools in Akwanga Local Government Area of Nasarawa State, Nigeria for 2022/2023 academic session. A sample of 125 (45 male and 30 female) SS II students from two Senior Secondary Schools in Akwanga, Nasarawa State, out of 127 students sampled, 75 (45 male and 30 female) are in experimental group and 50 (35 male and 20 female) are in control group through simple random sampling
technique. 50 multiple choice items with of 4 options Geography Achievement Test (GAT) was for data collection which was validated and established a logical and content index of 0.75 of expert and reliability of 0.86 for GAT using Kuder-Richardson method was used for the study. Descriptive statistics (mean and standard deviation) was used to analyze and answer the research questions while Analysis of Covariance (ANCOVA) was used to test the hypotheses at 0.05 level of significance. Finding from the study showed that the students taught using infographics model had higher achievement mean scores than those taught using conventional method, whilemale and female students in experimental group had similar achievement mean scores in posttest. The study concluded that infographics model is an effective method of teaching Geography in senior secondary schools in Akwanga, Nasarawa
State. The study therefore recommended that teachers and others relevant authority in field of teaching and learning should encourage the use of infographics model instructional approach, and teachers of Geography should be encouraged to usemore infographics model in teaching to improve the performance of students in the subject, regardless of gender of students.
