Effectiveness of Manipulative Materials in Teaching Mensuration

Abstract

This study entitled “Effectiveness of manipulative materials in teaching mensuration”. The main aims of this study were to compare the achievement of students taught by using instructional materials and without instructional materials and to find out the effectiveness of instructional physical materials on teaching mensuration. The research is based on constructivist view of learning and the design of this study was experimental research design under quantitative approach. Researcher used purposive sampling and selected sample schools from the Bardiya district. For the research purpose, researcher constructed a pre-test for measuring the knowledge level of 60 students of sample schools. Researcher constructed a pre-test on the basis of curriculum prescribed by CDC and administrated it and developed two groups as experimental group and controlled group. After fifteen days teaching and learning process on fifteen lesson plans, researcher had taken post-test on both experimental and controlled group. The collected data were analyzed by statistical method such as mean, standard deviation and t-test and came in conclusions. The finding of this research revealed that there was no significance difference between both experimental and controlled groups before conducting any treatment while teaching mensuration. But there is significance difference between the achievements of students taught by manipulation of instructional materials and achievement of controlled group who were taught by without using manipulation of teaching materials on mensuration at secondary level. Manipulative materials motivate the students for the mathematics learning. Researcher found that manipulation of materials is very essential for conceptual and meaningful learning.
