• SOME MATHEMATICAL MISTAKES ON RATIO AND PROPORTION (ALGEBRAIC TREATMENT)

Dr. SK. SAMSUL ALAM*

Abstract


In this paper, four problems concerning conceptual and operational mistakes are generally done by the learners in dealing with ‘Ratio and Proportion (Algebraic Treatment)’ and their proofs/solutions & explanation of the proofs/solutions of mistakes have been presented. This study has been done through ‘text book scanning’, ‘class room interaction’, ‘answer scripts of achievement test’ and ‘experts’ opinions’. This study will help the learners to understand important mathematical concept of ‘Ratio and Proportion (Algebraic Treatment) as well as entire teaching learning process of mathematics.


Keywords
