This paper evaluates the effect of constructivist approach on the achievement of Class VII students in the subject of Mathematics. Experimental research design was employed in the study. A sample of 189 students of Standard VII were divided into experimental and control groups. Percentage analysis, arithmetic mean and standard deviation were computed to know the nature of distribution. ANCOVA was used to find the influence of different approaches on the achievement in mathematics by considering pre-achievement in mathematics and intelligence as a covariate. Significant difference was found in the achievement level of students taught through constructivist approach in Mathematics. The study concluded that constructivist approach is largely helpful in enhancing the achievement level in the subject of Mathematics.
