The Effectiveness of "Nikilam Technique" in Subtraction of Numbers with Regrouping to Grades 5 and 6 Pupils

Abstract

INTRODUCTION

The study determined the Effectiveness of "Nikilam Technique" in the subtraction of numbers with regrouping to Grade 5 and 6 pupils in Lupi Central School, Lupi, Camarines Sur school year 2014-2015. Specifically, this research answered the following questions:1) What is the achievement level of pupils in Numeracy Test under Subtraction operation? 2) Is "Nikilam Technique" effective to enhance pupils' achievement level in the subtraction of numbers with regrouping? 3) What suggestions maybe recommended to improve the use of "Nikilam Technique" as a tool for Mathematics?

METHODS

The experimental research utilizing the one-group pre-test-post-test design was used in this study to determine the achievement level of pupils in subtraction fundamental operation by comparing the pre-test and post-test results of the pupils. A pre-test was conducted prior to the exposure of the pupils to "Nikilam Technique”. Afterward, pupils were measured through post-test and their score was compared.

RESULTS

The findings were as follows: 1) The achievement level of Grade 5 pupils prior to the exposure of the "Nikilam Technique" was 31.28% and the post-test was 84.72% with an increase of 53.44%. Grade 6 pupils obtained 90.72% over the pre-test which was 20.06% with an increase of 50.60%. Generally, the achievement level of pupils was increased. 2) Based on the result, the overall achievement level of pupils increased by 52.02% which was strongly related to the effectiveness of "Nikilam Technique" to pupils' achievement in subtraction operation with regrouping. 3) The following suggestions are recommended to improve the use of "Nikilan Technique: as a tool for Mathematics: a) Conduct LAC session to improve teachers' skills in using "Nikilam Technique" in teaching Mathematics; b) Start using "NIkilam Technique" in Grade I and continue up to higher grade; c) Practice the technique religiously in a day to day activity whenever applicable for mastery.

DISCUSSIONS

The results may serve as a solution to the teachers and pupils' difficulty in solving problems involving subtraction of numbers with regrouping. Once the teacher guides the pupils in using the technique properly, it would be a great advantage to both sides.
