The study examined the Scientific literacy of students when taught Biology using 3-empirical lenses. This was with a view to determining the effectiveness of Problem-based Learning (PBL), Argumentation-based Learning (ABL), and Visualised-Case-based Learning (VCBL) instructional strategies in improving the Scientific literacy of secondary school students in Biology. The study adopted the non-equivalent pretest-posttest control group experimental design. The population of the study comprised all senior secondary school Biology students in Osun state, Nigeria. The sample consisted of Senior Secondary Three (SS3) Biology students in their intact classes selected using multistage sampling procedure. From the three senatorial districts of Osun State, two senatorial districts were randomly selected. Also, two Local Government Areas (LGA) were sampled randomly from each of the selected senatorial district. Furthermore, one school was randomly selected from each of the selected LGAs to make a total of four schools for the study. Scientific literacy Test (SLT) was used to collect data for the study. Data collected were analysed using Analysis of Covariance (ANCOVA). The results showed a significant difference in the scientific literacy of students taught Biology using PBL, ABL, and VCBL (F = 25.960 p < 0.05), as the marginal means of participants exposed to ABL, Conventional Learning (CL), PBL, and VCBL instructional strategies are 9.646, 8.479, 9.007 and 11.929 respectively. This study found that participants exposed to VCBL instructional strategy appears to be more scientifically literate than participants in other groups after treatment.
