FEASIBILITY OF TEACHING THE d-h THEOREM FOR FACTORIZATION OF QUADRATIC EXPRESSIONS IN SHS1
Journal Title: Educational Research International - Year 2013, Vol 2, Issue 3
Abstract
This paper examined the feasibility of teaching the d-h theorem in SHS1. The study tried to find out if there is a significant difference between the scores of students who used d-h theorem and those who used the conventional method. Also, if students who used d-h theorem can remember and applied it as those who used the conventional method. The reliability coefficients of the tests were determined by the Cronbach Alpha method and Wilcoxon Rank-Sum Test was also used to test if the performance between both groups were significantly different or not. From the results, the reliability coefficients for all tests were above 70 percent. The results of the performance of the experimental group were better than that of the control group in test III and VII. This showed that students in the experimental group learnt and remember the d-h theorem and applied it more than their counterpart in the control group. In conclusion, the d-h theorem has the power that overcomes the inherent problems of the conventional methods of factorising quadratic expressions. Therefore, the d-h theorem holds a promise for mathematics education as a result a nationwide study is recommended to verify on a large scale the feasibility of the d-h theorem and subsequent inclusion in the core mathematics curriculum to help solved the problem of factoring quadratic expression.
