The twenty-first-century classroom comes with changes in instructional delivery. This has demanded a paradigm shift on pedagogical practices. In the Nigerian context, literature is scarce on the impact of two-dimensional (2D) animation on students' achievement. Thus, this study explored the impact of 2D animation technique on students' achievement in mathematical contents of Economics. Non-equivalent groups quasi-experimental design was adopted for the study with a sample size of 162 senior secondary 2 Economics students. The sample is made up of 80 male students and 82 female students drawn from four co-educational secondary schools in Enugu metropolis, Enugu State. Economics Achievement Test (EAT) was used for data collection. An internal consistency reliability coefficient of the items of the EAT was obtained to be 0.79 using Kudder-Richardson's formula 20. Data collected were analysed using mean and analysis of covariance. The results showed that students taught the mathematical contents of Economics with two-dimensional animation technique had significantly higher post-test and follow-up mean achievement scores than those exposed to the conventional method. Thus, the 2D animation technique impacted positively on students' achievement in mathematical contents of economics. This finding has implication for science teaching meaning that 2D can equally be applied in the teaching of mathematically related science subjects such as physics and chemistry. It was recommended among others that 2D animation technique should be used in teaching economics in secondary schools.
